Ten tips for disassembling and assembling the vacuum oil pump of the vacuum plasma surface treatment machine cannot be ignored:
The vacuum system of the vacuum plasma surface treatment machine is composed of connecting pipes such as a vacuum pump, a vacuum reaction chamber, a vacuum gauge, a baffle valve, an intake pipe, and a flange. As an important part of the vacuum system, how should the vacuum pump be disassembled and assembled? What else needs attention? Chengfeng Zhizao will give you a detailed explanation.

If there is no special requirement for the vacuum pump in the vacuum plasma surface treatment machine, most of the rotary vane oil pumps can be used. The working principle of the rotary vane oil pump is to mechanically pump the vacuum reaction chamber. When the vacuum degree can satisfy the plasma discharge, the process gas is kept in and the plasma reaction by-products are removed to ensure the stability of the plasma discharge. After grasping the correct method, the maintenance of the vacuum plasma surface treatment oil-type vacuum pump is actually very simple. Chengfeng Zhizao organized the disassembly and assembly steps of the vacuum plasma surface treatment oil pump.
Disassembly and assembly of the vacuum pump oil storage tank:
1. Before disassembling the oil tank of the vacuum pump, discharge the vacuum pump oil first, and tighten the oil drain screw with an Allen wrench to discharge the vacuum oil in the vacuum pump;
2. Use an Allen wrench to remove the fastening screws of the vacuum pump oil tank;
3. When disassembling the fuel tank, be careful not to damage the gasket of the fuel tank;
Gloves, masks and bags containing waste oil are the three necessary small items for vacuum pump maintenance. Various industries and products, the waste gas produced by plasma cleaning and various dirt produced by the reaction of vacuum pump oil, pay special attention to whether there are corrosive and toxic gases and liquids that harm the human body.
Disassemble the exhaust valve of the vacuum pump of the vacuum plasma surface treatment machine:
1. Remove the protective cover of the exhaust valve plate, fold off the sturdy protective cover screw, and remove the protective cover, taking care not to damage the sealing ring;
2. Disassemble the pressure plate of the exhaust valve plate.
3. Remove the exhaust valve piece.
Disassemble the vacuum pump rotor of the vacuum plasma surface treatment machine:
1. Remove the fastening screws of the rotor;
2. Remove the small screw cap and check the wear of the small screw cap at the same time;
3. Disassemble the cylinder cavity of the second-stage rotor, check the wear of the second-stage rotor, and check whether the oil circuit is blocked.
Remove the check valve of the vacuum pump of the vacuum plasma surface treatment machine:
1. Remove the fastening screw of the air inlet of the vacuum pump, take out the air inlet, and be careful not to damage the sealing ring;
2. Take out the limit circlip of the check valve, take out the check valve, check whether the air passage and oil passage are blocked, check whether the check valve has excessive resistance and whether there is any damage; if the check valve is stuck, when it is removed Be careful not to damage the pump body.
The assembly of the vacuum pump:
After the internal cleaning of the vacuum pump is completed, install the parts one by one in the reverse order of disassembly and assembly. Pay attention to inspection during assembly to avoid missing small parts and ensure that each part is installed in place.
Have you learned how to disassemble and assemble the oil-type vacuum pump for vacuum plasma surface treatment? It should be noted that you must not miss during assembly, please check repeatedly to ensure that every working part is installed in place.
