The application of vacuum pump unit _

Vacuum pump unit has been widely used in many fields:

1. The semiconductor industry: film making equipment, semiconductor device packaging equipment;

2。 Scientific instruments industry: synchrotron radiation beam line machine, electron microscope, vacuum pump unit aurora test equipment, analysis of test equipment;

3。 Machinery industry: material preparation equipment, testing equipment, vacuum vacuum filtration equipment, material purification equipment, ultra-high vacuum exhaust equipment;

4。 For medical devices industry: dental equipment, dialysis machine;

5。 Biological products: purification and drug preparation;

6。 The packaging industry, food, medicine, biological products and other packaging equipment;

7。 Vacuum metallurgical industry, vacuum furnace, nanomaterials preparation equipment, vacuum detection equipment, and other fields.

is a vacuum pump oil free vacuum system as molecular pump and the backing pump of small cryogenic pump configuration. The main moving parts only a vortex, simple, so the power of small movement radius under the same size, small parts, simple and compact structure, the machine size, between mobile and stationary vortex, the moving plate and the clearance between the pump chamber is small, the moving parts of pump and water pump cavity without friction, so almost no wear and tear, stable operation, low power consumption, small air flow loss, high working reliability, long service life, easy maintenance, low maintenance cost, high volume efficiency. High. Air, without water.

vacuum pump in a wide range of pressure pumping speed with high compression ratio and stable. As a result of the compression chamber volume change is continuous, so the drive torque changes little, changes in small power, low vibration noise. Do not provide the type of dry vacuum water pump. In order to achieve effective operation of the vortex pump, the rolling tube must be firmly meshing in each of the vacuum chamber, in order to avoid because of the vacuum chamber, the pressure difference between the thermal deformation and parts and led to the deterioration of vortex wall force. Exhaust chamber. High pressure gas reserves and reduce the vacuum pump efficiency. So we must ensure that accurate hold between vortex contours and mesh, to control the leakage of the working medium, and achieve the purpose of pumping. This is the important foundation of vacuum pump structure design. In pumping air flow path, do not need to use any oil and sealing liquid as the medium, and the mobile and stationary vortex relative rotation in order to form the suction chamber and the compression chamber to be pumping gas discharge, and suction, compression and exhaust process is completed. Therefore, how to prevent leak sealing solution is particularly important. Vacuum pump seals including axial meshing clearance of radial sealing and radial meshing clearance of tangential sealing, the side seal.
