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/

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. http://www.outesgroup.com/air-source-heat-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/

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. http://www.sunruimarketing.com/electro-chlorination-system/

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/

Baby feeding supplies are designed for feeding babies and young children with food and liquids. It includes feeding bottles, training cups, baby cutlery (spoons and forks), milk and formula storage bags and bottles, sippy cups, snack bowls and bibs, sterilizers, breast pumps and accessories, baby food, feeding bottles Cleaning supplies, pacifiers, bottle warmers, bottle coolers, high chairs, etc. A breast pump is a tool used to express breast milk that has accumulated in the breasts. http://www.babygear.com.cn/baby-feeding-supplies/

Casters are a general term, including movable casters, fixed casters and movable casters with brakes. The movable caster is also called the universal wheel, its structure allows 360-degree rotation; the fixed caster is also called the directional caster, it has no rotating structure and cannot be rotated. Usually two kinds of casters are used in combination. For example, the structure of the trolley is two directional wheels in the front, and two universal wheels in the back near the push armrest. http://www.blyshares.com/casters/

The development trend of thin and light consumer electronic products such as smartphones and wearable devices is accelerating, and the core components of such products are also becoming more sophisticated and complex. In this context, the application prospects of the MIM process are becoming increasingly clear. At present, the process has been widely used in the manufacture of MIM communication parts such as card trays, camera rings, buttons, connector joints, built-in structural parts, watch cases, and buckles. http://www.chinamim.com/mim-communication-parts/

A steel can, tin can, steel packaging, or can is a container for the distribution or storage of goods, made of thin metal. Many cans require opening by cutting the "end" open; others have removable covers. They can store a broad variety of contents: food, beverages, oil, chemicals, etc. Steel cans are made of tinplate (tin-coated steel) or of tin-free steel. In some dialects, even aluminium cans are called "tin cans". Most cans are right circular cylinders with identical and parallel round tops and bottoms with vertical sides. http://www.gscustomize.com/tin-cans/

Drying machines can be divided into two types: industrial and civilian. Industrial dryers are also called drying equipment or dryers. Civilian dryers are a type of washing machine. They are generally used to remove clothing and other textiles after washing with water. of moisture. The dryer has several modes such as belt drying, tumble drying, box drying, tower drying, etc. The heat source includes coal, electricity, gas, etc.; the material has hot air flow type and radiation type in the drying process. http://www.lffoodmachine.com/fruit-vegetable-processing-machine/drying-machine/
