Vortex pump has a long history of development, and trace back, the original prototype is still in China, and the real centrifugal pump was invented by the United Kingdom. Zhenjiang air pump is an air pump powered by electricity, which compresses air continuously and produces air pressure. Mainly used in pneumatic gluing, car inflatability and so on. At that time, the equipment (shbi), impeller (referring to the wheel with movable blades) and chassis were concentric circles, and the material was relatively common. The chassis was made of bricks, and the impeller (referring to the wheel with movable blades) was made of wood impeller (referring to the wheel with movable blades), so the efficiency of work was very effective.
After continuous practice and improvement, a relatively perfect air pump has been developed, and widely used in chemical industry, petroleum, machinery and other fields. This kind of device mainly plays a huge role in ventilation and dust removal devices to ensure Jieneng environmental protection. In addition to the type of air pump itself, the most important thing is to adjust the air pump reasonably, because the actual working state is constantly changing, and the air pump should adjust the flow rate according to the main engine conformity (unit: cubic meters per second).
At present, the commonly used way is throttle adjustment, that is, the use of regulating valves (using materials: cast iron, cast steel, stainless steel, etc.) door or throttle baffle (Tailgate) to regulate, but found that the energy waste is very serious. Carbon refined sheet is also called vacuum pump carbon sheet. The vacuum pump carbon sheet is made of graphite material and carbon particles. Vacuum pump carbon sheet is self-lubricating carbon sheet, which has strong wear resistance. Zhenjiang air pump, or "air pump", is a device that removes air from a closed space or adds air from a closed space. Air pumps are mainly divided into electric and manual air pumps, foot air pumps. Electric air pump. If the operating speed of the air pump is adjusted, the throttling loss can be eliminated and the stable operation of the equipment (shbi) can be guaranteed, so as to reduce the consumption of energy.
