How Does A Power Inverter Work
How Does A Power Inverter Work
People always ask us “exactly how does a power inverter work?” The answer to this question often surprises our customers. Car power inverters work much more simply than mysteriously, and the learning curve required to understand them requires no more than a very basic knowledge of electricity. Essentially, there are two forms of electrical power in the Universe: Direct Current (DC) and Alternating Current (AC). Direct current flows continuously from the positive electrical pole to the negative electrical pole. Alternating current flows back and forth between the two poles.
DC current occurs in Nature and batteries, while AC current is man-made and supplies power through the public utility grid that supports human industry and infrastructure. Car batteries presented a problem in the past when people realized they needed to operate traditionally AC-powered devices in their cars but could not do so because of incompatible current requirements. Manufacturers like Vector stepped up to solve this dilemma by working to design car power inverters that would safely and efficiently convert DC to AC. Their successful engineering has resulted in a wide range of compact, rectangular devices that connect to batteries and output the resulting alternating current safely through one or more standard electrical plugs.
Two factors determine how a power inverter works: wave output and wattage output. Wave output describes the physical appearance of electrical signals as they move across an oscilloscope. Square waves appear exactly as their name specifies: like squares on a grid. Pure sine waves, also called true sine waves, appear as visible waves on the screen. Sine wave car power inverters work better than square wave power inverters when uninterrupted power flow is a critical issue.
In fact, true sine output is sometimes slightly superior to that of public utility power grids! Because of this, they are also the most expensive devices of their kind on the market. Recent advances in technology have accommodated users on a budget with a hybrid design generally referred to as either a modified square or modified sine wave power inverter. The technical differences that determine how a true sine car power inverter works and how a modified sine power inverter works are too minor to produce any noticehttp://www.carspa.cn/

Countertop Materials, Ranked by Stain-Resistance
Countertop Materials, Ranked by Stain-Resistance

Most countertop manufacturers market their products as stain-resistant or stain-proof, but there is often a major caveat. Many countertop materials resist stains only if maintained properly — and even with sealing and care, they aren’t always 100-percent stain-proof. Here is a list of the 16 most popular countertop options, in rough order from the most stain-resistant to least stain-resistant.

Quartz countertops are really an engineered stone surface made primarily of quartz crystals with some additives. They are very resistant to stains and heat, and are anti-bacterial. If durability and ease of maintenance are more important than cost, quartz is certainly a good option.

Traditional stone products like Granite and Quartz also offer a staggering range of colors, edge options, and even a few different finishes on the surface. The most common finish is glossy; however, "leather" (matte) finishes are becoming more popular. Some stone countertop manufacturers are also capable of applying a variety of other finishes to the surface of stone.

Solid-surface countertops, better known as Corian or Wilsonart, are also among the lowest-maintenance options available, and is typically a little cheaper than quartz. They will resist most stains, and the rare stain is easily repaired with an abrasive cleaner and scrubber or, in extreme cases, some fine sandpaper.

Glass countertops also are very stain-resistant, but they require more maintenance and care than solid-surface. While wine or mustard may not mar glass, simple fingerprints and watermarks are quite visible.

Stainless steel and copper countertops are similar to glass in their stain-resistance. They are technically stainproof, but watermarks, fingerprints and grease marks can be obvious and ugly.

Richlite is a paper-based fiber composite that looks like real wood but is more stain-resistant and requires less maintenance. Like many other countertops, it can be sealed to resist most stains.

Slate is stain-resistant and doesn’t need to be sealed, but it scratches easily.

Granite is rarely this far down any list of countertop options. To be sure, some high-end granite is quite stain-resistant and may not even require sealing. However, most granite on the market must be sealed, and is not stain-proof.

Porcelain tile resists stains. Unfortunately, the same cannot be said of most tile grout. Grout can be difficult to clean, and must be sealed regularly to resist stains.

Ceramic tile, particularly glazed tiles, also resist stains. But grout presents the same problem as with porcelain tiles.

Natural stone tile is a cheaper way to get natural stone onto your kitchen or bathroom countertop, but it is also a more stain-prone. Both the stone and the grout can stain, though grout lines are typically thinner than on other tile surfaces.

Soapstone can take on surface stains, but they are typically scrubbed or sanded away with relative ease. http://www.modernday-kitchen-cabinets.com/

Reducing Overall Supply Chain Costs Top Priority Among Manufacturers
Reducing Overall Supply Chain Costs Top Priority Among Manufacturers

When IDC Manufacturing Insights announced the results of the 2012 U.S. Supply Chain Survey, analysts were surprised by some of the findings.

The survey which examines the state of the industry, and how kitchen cabinets manufacturers are adapting and improving their supply chains, also explores and how technology plays a role in enabling kitchen cabinets manufacturers to be more successful.

“We were expecting respondents to say they were continuing to invest in technology,” said IDC Manufacturing Insights Practice Director, Kimberly Knickle, “but we were pleasantly surprised that product quality was also ranked high on their list of priorities.”

“Business Strategy: 2012 Supply Chain Survey-Manufacturing Priorities and New Technology Adoption” is based on feedback from 350 U.S. kitchen cabinets manufacturers. It found more than despite being product-centric organizations, 80 percent of respondents rate reducing overall supply chain costs as the number one supply chain priority in the coming year. Nearly 55 percent suggest supply chain agility is second and 52 percent suggest improving product quality and safety is the third most important priority.

When asked to rate the level of importance of new technology areas, big data/analytics came out on top, followed by mobility, cloud computing/software as a service and social business tools.

In an interview, Knickle said “reverse logistics” represented a large piece of the puzzle.

While kitchen cabinets manufacturers face increasing complexity as customer demand diversifies and supply globalizes, supply chain organizations are adapting to respond to requirements such as:

? Complex and extended global supply networks

? Volatile demand

? Growing regulation, particularly in the area of traceability

? Pressure to be more agile and increase the clock speed of the supply chain

? The “rise” of the savvy consumer

To address these challenges, IDC Manufacturing Insights has found:

? kitchen cabinets manufacturers continue to increase the amount of low-cost country sourcing. IDC Manufacturing Insights recommends revisiting the profitable proximity sourcing approach and how that concept, supported by IT, can ensure sourcing decisions to create a competitive edge.

? Most kitchen cabinets manufacturers view their supply chains as focused primarily on product quality, yet their supply chain priorities usually start with reducing costs, followed by responding to supply or demand changes, ahead of product quality and customer service.

? With IT-based solutions for demand planning and forecasting and production scheduling viewed as key to kitchen cabinets manufacturers’ business performance over the next year, this could signal a genuine shift to a more holistic approach to truly integrated business planning, inclusive of fulfillment excellence.

? Big data and mobility are the most important new technologies for kitchen cabinets manufacturers’ supply chains. IDC Manufacturing Insights believes there is substantial value to how kitchen cabinets manufacturers can use these to improve their agility and customer service. http://www.modernday-kitchen-cabinets.com/

Electric Fuel Pump For Optimum Function
Electric Fuel Pump For Optimum Function

Accuracy and precision play vital role in management of fuel efficiency. Fuel being an exhaustive input resource, it is mandatory to ensure its efficient and effective utilization to ensure optimum outputs. With effective utilization of electric fuel pump, oil transfer pumps and diesel fuel meters, it is possible to ensure fuel efficiency as well as monitoring of fuel consumption. These factors not only improve the output but also help keep a watch on the efficiency and working condition of the engine driven machinery.

electric fuel pump are available for private use of fuel dispenser. These are easy to install and provide precision and accuracy in function. With the incorporation of security software to eliminate unauthorized usage, these electronic fuel pumps ensure a convenient and effective solution for fuel dispensers. The electronic unit can control up to 50 users by the utilization of magnetic keys or access codes. These can also mounted on walls and thus offer convenient usage. These pumps can be supervised by connection to a computer unit and provide information about every dispersion. There fore monitoring of all the activities becomes convenient. Backed with sufficient memory to store data along with precise functioning and ease of monitoring, these electric fuel pump surely have an edge over the conventional pumps.

Oil transfer pumps are an important component of mechanized devices running on oil as fuel. These pumps transfer the oil from the fuel tank to the through a tube. Carburetted engines use low pressure mechanical oil transfer pumps which are mounted outside the fuel tank, whereas fuel injected engines use electric fuel pump which are mounted inside the fuel tank. These pumps are especially of great utility in engines where gravity does not facilitate fuel flow. These permit accurate and smooth fuel movement. A disruption in the pathway of fuel can cause damage to the engine apart from extensive inconvenience to the operator. Incorporation of air bubbles can jeopardize the engine thus oil transfer pumps play a vital role in engine functioning as well as its maintenance.

Diesel fuel meter is able to measure very low flow rates of liquids and thus give an accurate impression of the fluid utilization. Flow meters of various kinds are available depending on the kind of fluid being monitored. While magnetic flow meters are used for water applications, electronic and DEA micro flow meters are available for a wide variety of applications. Micro flow meter is a reliable product. It is based on the principle of physics which states that the amount of liquid displaced is equal to the difference in volume of the chambers and volume of pistons. The process completes in a continuous flow at a rate of 1 to 210 cycles per second. To displace one gallon of liquid approximately 200,000 cycles will work. Light interruptions of a detector device are used for recording flow at a particular instance. With ease of operation and low cost, these fuel meters are an effective tool for monitoring diesel usage and thus can be used to interpret the efficiency of the engine. http://www.chinadkk.com/

Symptoms of a Faulty Lambda Sensor
Symptoms of a Faulty Lambda Sensor

A Lambda sensor measures the amount of unburned oxygen in a vehicle s fuel exhaust. If the oxygen level is too high or too low, the Lambda sensor sends a signal back to the vehicle s computer that tells it to adjust the air/fuel mixture so that the vehicle can perform optimally and within emission control standards.A Lambda sensor may become damaged, sluggish or completely fail. If any of these symptoms occur, a vehicle owner should address them soon, as waiting may cause further complications.

Poor Mileage

If a driver were to notice that he is not getting usual miles per gallon numbers, it may be the fault of the Lambda sensor because the vehicle s computer is not receiving notifications to change the air/fuel ratio, and the mixture might be too rich, consuming unnecessary fuel amounts. According to Fueleconomy.gov, the repair of a faulty sensor may increase mileage by as much as 40 percent.

Unusual Lurching Or Hesitation

An early warning signal of lambda sensor failure in the form of an uneven idle can be noticed by a driver who feels the vehicle wanting to surge ahead when at a red light or stop sign. Or, conversely, when it is time to go, the driver feels the vehicle hesitating after the accelerator is applied.

Smell

A cold engine with a faulty Lambda sensor that has unburned oxygen in the catalytic converter may emit a "rotten egg" smell.

Decreasing Engine Power at Cruising Speed

A malfunctioning Lambda sensor may send an erroneous signal that the air/fuel mixture is too rich. The vehicle s computer will make the correction according to the signal that the Lambda sensor sent, decreasing the amount of fuel in the ratio, causing the spark plugs to misfire.

Emissions Test Failure

A malfunctioning Lambda Sensor may cause a vehicle s exhaust to be too rich in unacceptable emissions (unused hydrocarbons and carbon monoxide). http://www.chinadkk.com/companyInfo.html

Symptoms Of Defective Oxygen Sensor
Symptoms Of Defective Oxygen Sensor

The oxygen sensor eventually needs to be replaced in all vehicles. But how would you know if the oxygen sensor has gone bad? There are signs you should look for to diagnose a faulty sensor.

The oxygen sensor or O2 sensor as it is commonly called plays an important role in monitoring the oxygen content of the car s exhaust system. It determines the optimal mixture of air to fuel ratio needed to run the vehicle. A defective sensor can greatly affect your vehicle s fuel consumption because it allows the vehicle to use more fuel than what it should. Hence faulty sensors need to be diagnosed and replaced promptly.

But determining if the O2 sensor is really defective will need accurate diagnosis. Let s see what are the symptoms of a faulty O2 sensor:

1] The symptoms of a faulty O2 sensor starts with sudden decrease in vehicle s gas mileage (the vehicle starts consuming more gas than usual). A defective sensor makes the air-fuel mixture to run too rich or too lean resulting in poor fuel economy.

2] The defective oxygen sensor also shows up as a check engine light or malfunction indicator lamp illuminating in the vehicle s dash board. But this can happen due to many other reasons (defective oxygen sensor being one of them).

3] Perhaps the most accurate diagnosis of a defective oxygen sensor can be done using an OBDII code checker. The OBDII code checker is capable to identifying the defects in the exhaust system of the car including identify a fault oxygen sensor. Please note that only cars made in 1996 and after are equipped with OBDII interface. OBDII code reader will generate a diagnostic trouble code that can indicate with specific oxygen sensor has gone bad.

4] Smog test failures can also be an indication of a failed oxygen sensor. EPA (Environmental Protection Agency) and CARB (California Air Resource Board) 50 to 60% of all smog test / emission test related failures are attributed to the defective oxygen sensor. Faulty O2 sensor leads to either low or high CO emissions in the smog tests.

Since proper functioning oxygen sensors are vital for the optimal fuel consumption in the car, its best to replace the faulty sensor when in doubt.

Following are the guidelines you can use for replacing the oxygen sensors in your vehicle:

A] The unheated 1 or 2 wire O2 sensors, used in vehicles from mid-1970s through early 1990s should be replaced every 40,000 to 50,000 miles.

B] Heated 3 and 4 wire O2 sensors, used in the vehicles from mid-1980s through mid-1990s should be replaced every 60,000 to 70,000 miles.

C] Newer vehicles made in mid-1990s and later, recommend replacing the oxygen sensors every 100,000 miles. http://www.chinadkk.com/products/oxygen-sensor.html
