Piston Vacuum Pump of sale
Piston vacuum pump is a kind of variable capacity gas transmission pump as well as rotary vane pump, but compared with 2X rotary vane vacuum pump, the durability is several times higher. Its scope and conditions of use are basically the same as those of rotary vane pumps. The Shanghai EVP spool vacuum pump is divided into two types: single stage H and bipolar 2H. Piston vacuum pump sale two hot products.
Piston vacuum pump structure
Piston vacuum pump is composed of pump body and eccentrically rotating sliding valve parts, semi-circular sliding valve guide rail, exhaust valve, shaft, etc.

Piston vacuum pump principle
The shape and structure of various vacuum pumps of the piston vacuum pump are basically the same. The pump is driven by the motor through the triangle belt to the pump rotor. The motor is fixed on the pump body by a motor plate.
There is a slide valve sleeve in the pump body of the piston vacuum pump. The eccentric wheel is fixed on the shaft. A rectangular slide valve plate is installed on the slide valve sleeve. During the operation of the pump, the volume of A and B two chambers change periodically, thus completing the inspiratory and exhausting process.
Piston vacuum pump features
The main parts, such as the piston vacuum pump body, are made of wear-resistant and high-silicon baking vacuum casting, and are finished by surface treatment and one-time clamping in the machining center. It has the characteristics of high precision, low wear and less maintenance.
Piston vacuum pump application
Piston vacuum pump can be used alone, also can be used as diffusion pump, oil booster pump, roots pump and other high vacuum pump front pump, relative to rotary vane vacuum pump, H type sliding valve pump is more durable, piston vacuum pump service life is long. piston vacuum pump is widely used in vacuum coating, vacuum heat treatment, vacuum sintering, molecular distillation, aviation simulation test.
