Part of high-viscosity rotor pump parts 1. High-viscosity rotor pump shaft in the front end with a stuffing box, the sealing performance is more reliable, 2. High-viscosity rotor pump bearing set with mechanical seal and packing seal, so a lot of liquid Leakage can not occur, and a small number of leaks can be discharged through the leak nozzle to receive a small amount of leakage in the early start of the run is normal, after a certain period of running on the seal surface leakage will be reduced or stopped. The suction pipe diameter of the pump is generally large, and sometimes the use of diffusion-type suction port to expand the volume of low-pressure zone to reduce the flow rate of the inlet liquid to reduce the pump suction resistance.This structure can also reduce the role of the shaft The radial force on the neck and the bearing prolongs the service life of the high-viscosity gear pump 4. The outlet pipe of the high-viscosity rotor pump is also provided with safety valves and other protective devices so that once the pump outlet passage is blocked, the safety valve can be opened Pressure relief. Safety valve can be cast with the pump body or pump cover can also be a separate assembly, installation of safety pump and motor play a protective role. 5. High-viscosity rotor pump in the pump plus insulation sleeve, you can do insulation pump use, insulation jacket overall casting, insulation effect, zero leakage.
