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. http://www.zlocomotive.com/water-pump/

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. http://www.ouyalibbq.com/outdoor-bbq/

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). http://www.keditesensor.com/intake-air-pressure-sensor/

Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels. The electricity is stored on board in a rechargeable battery, which drives one or more electric motors. Electric scooters (as distinct from motorcycles) have a step-through frame. Electric vehicles are far quieter than gasoline powered ones, so silent they may sneak up on unwary pedestrians. Some are equipped to emit artificial noise. http://www.isooyuelectricbike.com/electric-motorcycle/

A toilet is a piece of sanitary hardware that collects human urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia. In urban areas, flush toilets are usually connected to a sewer system that leads to septic tanks in Isolated areas. http://www.fabiaosanitary.com/toilet/

A picture frame is a protective and decorative edging for a picture, such as a painting or photograph. It makes displaying the work safer and easier and both sets the picture apart from its surroundings and aesthetically integrates it with them. A picture frame is a container that borders the perimeter of a picture, and is used for the protection, display, and visual appreciation of objects and imagery such as photographs, canvas paintings, drawings and prints, posters, mirrors, shadow box memorabilia, and textiles. http://www.dugaohouse.com/picture-frame/

Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges. A manometer is a good example, as it uses the surface area and weight of a column of liquid to both measure and indicate pressure. http://www.brgsensor.com/pressure-measurement/
