中文Rotary pump: disassembly and assembly of cam rotor pump
2020-10-15
Cam rotor pumps are suitable for transportation with low viscosity between 0.02 and 100 Pa Heavy oil, petroleum, raw material oil, Huai grease, vulcanized rubber, fiberglass, and asphalt with a temperature below 200 ℃. All the physical properties of whitening toothpaste, skincare products, viscous food products, ointments, vegetable oils, printing inks, and chemical fiber slurries ensure that the original quality is not harmed in the slightest, and are also suitable for transporting various corrosive liquids containing solid particles.
Disassembly and assembly of cam rotor pump:
When disassembling and assembling a cam rotor pump, the first thing to do is to carefully read the instructions or consult with the staff to master the internal structure and disassembly process, production process, and operating conditions; Be cautious when disassembling and assembling cam rotor pumps to avoid damaging machine equipment components.
Carefully inspect the disassembled cam rotor pump and check if there are cracks on the motor rotor; The taper of the motor shaft meets the standard, and there should be no scratches on the surface. The maximum allowable value of surface roughness Ra is 1.6 μ m; Is there any damage to the internal components
The cam rotor pump should be repaired, and the severely damaged parts should be replaced. For the parts that need to be repaired, they should be adjusted to meet the standards.
The pressure test of the cam rotor pump is 1.5 times the pressure, and there is no leakage after persisting for 30 minutes. The trial operation time is without any leakage, and the operating sound is normal without any abnormal vibration. The working pressure at the inlet and outlet meets the requirements to meet the standard.
After the cam rotor pump is in normal operation, it is necessary to carefully observe the load bearing condition of the motor. If the motor does not generate heat and lasts for thirty minutes, everything is normal, which can ensure that the cam pump is in normal operation.
