Vacuum pump stator curve is how requirements of _

vacuum pump is the use of machinery, physics, chemistry or physical chemistry method emptying device for vacuum pump container. Usually, the vacuum pump is a kind of use various methods to improve, to create and maintain the vacuum equipment in enclosed Spaces. Today we will discuss the stator curve of vacuum water pump requirements.

a, the appropriate distance between two points: because the blade is a whole solution, thus improves the rigidity, and the end of the elastic must form the other end of the corresponding elastic. Therefore, whether the rotor to a certain Angle. Must ensure that the ends of the curve and the rotor contact together. Adhere to the reasonable open space. Avoid even the appearance of pores and increase ventilation.

two, leaves no shock oscillation, super excited: can't have too much noise in the smooth stator curve of acceleration, speed up the assembly rotary vane pumps will lead to a end to increase pressure on the surface of the stator curve, increase the wear and sound. However, suppose that the radial velocity 4) At a point on the stator curve changes, the point of the radial acceleration will increase. In theory, equal to infinity. If a is infinite. When the blade seems to have been separated, and will make a big impact. It forms a lot of buzz and serious friction. In order to eliminate this kind of phenomenon, need to repeatedly lubrication of stator curve.

3, the rotation of the rotating parts is wonderful: the point of the stator curve curve and the point of the point of the Angle between the normals of stator curve of pressure Angle. The increase of the pressure Angle will increase on the rotor blades of the Angle between the direction of the force of the stator and the rotor blades, this would increase the lateral force of the rotor blades, increase the conflict between the rotor blades and rotor, and the pressure of the blade. Affect the service life of the water pump and the overall power.

4, large pumping speed: vacuum water pump don't increase the pump body size, increase the volume of rotary vane pump element area as far as possible, in order to obtain higher pumping speed of the string.

new stator curve, and increase the pumping speed, also should have the velocity and acceleration characteristics of existing curve. Now, the vacuum pump stator curve is mainly controlled by the ideal of circular curve. Is the main factor is return curve has good speed and acceleration characteristics, thus reducing the vacuum pump noise and impact during operation.
