The rotary vane vacuum pump has brought convenience to people’s work and is deeply loved by people. How much do you understand about the knowledge of vacuum pump’s oil discharge? The following is the introduction of the imported vacuum pump oil drainage method, I hope you useful!
Method of oil displacement of rotary vane vacuum pump:
1. If all the vacuum pump oil in the box body of the rotary vane vacuum pump is to be discharged, the oil drain plug at the bottom of the box body can be screwed off to drain the oil.
2. Vacuum pump oil discharge of oil, liquid level interval tank roof height don’t exceed 30 mm, in order to ensure the smooth and cooling of each bearing in the pump, when jack working chamber volume is too large, need to pay up fuel tank, ensure that the discharge of oil liquid level after the minimum height not less than 100 mm in order to avoid empty absorption.
3. After the first 500h operation of speed-regulating vacuum pump, the oil tank and filter should be replaced and cleaned. Use visual and laboratory tests to test the oil and replace it when the oil deteriorates. The oil tank and filter must be cleaned simultaneously when changing oil. If there is metal chip or water in the oil, should look for the reason side by side the problem.
4.The liquid level lower bearing in a short time by oil splashing of oil and plunger spring to be smooth, about the oil tank and pump the oil filter is 230 mesh/inch copper wire mesh, oil screen should often clean to prevent infarction, when using the oil tank temperature should not exceed 60 ℃, take appropriate measures when necessary to cool.
