There are usually five materials: plastic, aluminum alloy, cast iron, stainless steel, and Teflon.. The transmission part is a driving mechanism that drives the diaphragm to agitate back and forth. The transmission part and the diaphragm cylinder head are composed of two parts. The common ones are steam jet pump, air jet pump and water jet pump.

Although both diaphragm pumps and jet pumps belong to the category of pumps, their functions are quite different. The jet pump and the pneumatic diaphragm pump are completely two items, and the jet pump is a fluid power pump. Rongpeng pneumatic diaphragm pumps are widely used in painting and ceramic industries. Today we are mainly talking about pneumatic diaphragm pumps.

There is also a jet pump that uses oil as a medium, namely oil China drainage pumps manufacturers diffusion pump and oil booster pump, which are the main equipment used to obtain high vacuum or ultra-high vacuum. It uses compressed air as the power source. Diaphragm pumps are distinguished between pneumatic and electric. It mainly uses the energy of another working fluid as a power source to transport low-energy liquids to suck inflammable and explosive materials. The working fluid of the jet pump can be gas (air or steam) and liquid. Its transmission forms include mechanical transmission, hydraulic transmission and pneumatic transmission

The key technical point of the dry gas seal is the groove. Nowadays, there are many domestic seal manufacturers. The seal of this structure is actually in a state of slight leakage, and the approximate design value is not more than 5ml/h (considered according to the shaft diameter and speed), it is basically in the naked eye The state of the leak is not visible. Therefore, it is incorrect to say that Gao Fei said that the device that seals the liquid in the pump cavity of the centrifugal pump by using the mechanical force of the centrifugal pump is incorrect. The hot sleeve static ring and the hot sleeve moving ring The end faces fit together for relative movement under the action of spring force
