A water pump is a machine that transports or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid energy, and is mainly used to transport liquids including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures and liquids with suspended solids can also be transported. The technical parameters of pump performance include flow, suction, head, shaft power, water power, efficiency, etc.

Electro-chlorination system is the syetem of producing hypochlorite by passing electric current through salt water. This disinfects the water and makes it safe for human use, such as for drinking water or swimming pools. The process of electrochlorination is simple. It is the electrolysis of saltwater to produce a chlorinated solution. The first step is removing any solids from the saltwater. Next, the saltwater streams through an electrolyzer cell's channel of decreasing thickness.

Barbecue is a term used with significant regional and national variations to describe various cooking methods which use live fire and smoke to cook the food. The term is also generally applied to the devices associated with those methods, the broader cuisines that these methods produce, and the meals or gatherings at which this style of food is cooked and served. What is different from general cooking is that most people will choose outdoor BBQ.

An air source heat pump (ASHP) is a type of heat pump that can absorb heat from outside a structure and release it inside using the same vapor-compression refrigeration process and much the same equipment as air conditioners but used in the opposite direction. Unlike an air conditioning unit, most ASHPs are reversible and are able to either warm or cool buildings and in some cases also provide domestic hot water.

The intake air pressure sensor is connected to the intake manifold by a vacuum tube. With the different speed loads of the engine, it senses the vacuum change in the intake manifold, and then converts the change of the internal resistance of the sensor is converted into a voltage signal for the ECU to correct the fuel injection amount and ignition timing angle. In the EFI engine, the intake pressure sensor is used to detect the intake air amount, which is called D-type injection system (speed density type).
