A true maintenance-free battery does not exist. Even with sealed batteries that do not require water, the terminals should be checked periodically and cleaned, and tightened if necessary. For open cells, the main maintenance requirement is the regular addition of distilled or demineralized water. All battery periodic maintenance procedures should attempt to identify faulty cells or blocks. This can be done with specific gravity measurements (not possible with sealed batteries), voltage checks...

Metal stamping involves placing a sheet or coil of metal into a press and forming it into the desired shape on a die or die. This can be done in one stage or in multiple stages, depending on the complexity of the desired end product. Stamping technology allows the manufacture of many different stamping automotive parts, which are used in vehicle bodies and frames, as well as electrical, steering, alternator, and fuel systems. These components play a vital role in ensuring optimum safety and f...

Typically, manufacturers of sealed gel batteries specify a float service life of 3-5 years, depending on the depth of discharge, over 1000 discharge and charge cycles can be expected. High temperatures are the real killer of batteries. When a system is designed for an internal battery, it is best to keep as much space as possible between the battery and heat sources such as transformers and power transistor heat sinks. While this is usually not practical or even possible, battery life will be ma...

The most efficient solar panels on the market today have efficiency ratings of up to 26%, and they are both monocrystalline and polycrystalline, while most panels are between 11% and 17% efficient. PV module efficiency refers to the ability of a solar panel to convert sunlight into electricity. Given the same amount of sunlight shining on two solar panels with different efficiency ratings for the same duration, the more efficient panel will generate more electricity than the less efficient panel...

The tensioner, idler, and damper are three very important engine components. Your car cannot run without them. The tensioner adds to pressure from an adjustable pivot point or spring mechanism to keep the serpentine belt taut as it circulates around the engine. ...

Generally, synthetic leather other than genuine leather such as PVC and PU leather are collectively referred to as artificial leather or imitation leather. Both PVC and PU are polyvinyl chloride (a type of plastic), but the manufacturing processes of these two products are different. In the manufacturing process of PVC leather, the plastic particles should be hot-melted and stirred into a paste, uniformly coated on the T/C knitted fabric base according to the specified thickness, and then ent...

The clutch cover is cold-formed from a 2.5-4mm thick steel sheet. It is then aligned relative to the flywheel axis with the aid of dowels, collars, or bolts. The clutch pressure plate is also made of cast iron. The clutch plates, as well as all other rotating parts of the clutch, have a flywheel effect. The plate becomes stiffer to distribute the pressure more evenly. Provides more heat capacity and heat dissipation surface. The pressure plate must be driven from the flywheel by a number o...

Lead-acid batteries come in a variety of designs and sizes. Available with vented or valve-regulated batteries. Products range from small sealed batteries around 5 Ah (e.g. for motorcycles) to large ventilated industrial battery systems up to 500 Ah for traction applications. What situations can cause battery safety accidents? Mechanical Abuse: Mechanical mishaps or mechanical misuse of LA batteries can result in hazards of varying severity, depending on the circumstances. Simple mechanical d...

MPP was prepared by supercritical carbon dioxide technology. Carbon dioxide gas was introduced into the polypropylene material matrix under high temperature and high pressure, and its nucleation and foaming were induced to form a microcellular foamed material containing a large number of micron-scale cells. The foaming process is clean and pollution-free, and the foamed products are hygienic and environmentally friendly. The PP material is not cross-linked during the foaming process, so it can b...

As a kind of safety glass, when the laminated glass is impacted and broken, due to the bonding effect of the two ordinary glass interlayer films, it will not produce sharp fragments like ordinary glass when it is broken, which will hurt people. At the same time, the sound insulation and sunlight control properties of the laminated film make it a new type of building material with energy-saving and environmental protection functions: the use of laminated glass can not only isolate the penetrable ...
