Oil leakage from the lubricant after major compressor repair

I don’t know what the original poster means?

After a major overhaul of the press, the lubricating oil tank must be thoroughly cleaned, and strict inspection is required for acceptance. The refueling process also needs to be carefully controlled. 1. Is it running with the fuel station filter in place? At the gas station, filters are used in a tandem configuration, with one filter in operation and another as a backup. The cleaner filter element can be kept, as it provides effective filtration against oil leakage and helps to shorten the interval between such leaks; the dirty filter element is simply removed. 2. How long should the pump run before it is stopped to clean the filter screen? Depending on the cleanliness of the filter used, if it’s dirtier, clean it every 2 hours; if it’s cleaner, then every 4 hours. If the crew isn’t in a hurry to depart, it’s fine to fly a bit longer. 3. What are some good practices? There is an oil dehydration system that can be considered for use; it comes with a filter and is very effective at preventing oil leakage. Pay attention to keeping the oil temperature at 40°C (a slightly higher temperature than normal operation, which improves the filtering effect). When the filter screen is dirty, it may be necessary to replace it. 4. I hope experts can give some advice; I’m waiting for their guidance to learn more*

Just add a filter to the return oil main pipe; there’s no need to disassemble the oil pump inlet

It is recommended to express the issue in detail to facilitate discussion.

Installing a filter on the return oil main pipe is not appropriate, as it can easily lead to poor oil return flow and a filled oil pipe. It is recommended to install a filter at the inlet of the bearing bush; an alarm will be triggered when the oil pressure rises, which facilitates monitoring and cleaning, and also ensures that the incoming oil is clean!

What type of engine unit is the poster talking about? Oil leakage usually occurs along with the use of filter elements; it is best to install 100-mesh or 120-mesh oil leakage filters at each oil inlet flange of the unit. At first, inspections should be carried out every half hour, and if there are few impurities present, inspections can be done every two hours. Generally, the system becomes cleaner after 24 hours. If oil leakage continues, it is possible to determine whether the filters need to be cleaned by checking the pressure difference in the oil system. After the oil leakage stops, it is essential to ensure that all oil leakage filters have been removed and replaced.

Install a filter at the main pipe to prevent oil leakage; the connection via hoses should be severed at the point where it enters the bearing shells. If the connection cannot be severed, then a filter element must be installed at that entry point. In any case, it is essential to prevent impurities from reaching the bearing shells and gearbox.

What compressor? Screw, piston, or centrifugal – what type of evaporator? The most basic things weren’t even mentioned; there’s nothing to answer

The poster probably means oil washing after a major repair. The method I use here is for reference only. 1. Install a temporary filter with a mesh size of 100-120 on the return oil main pipe; assign 2 personnel, one to start and stop the pump and the other to monitor the site, especially the return oil sight glass at the lowest liquid level. The station filter was taken away along with it, as was the filter at the oil pump inlet. 2. Start the pump; once the fluid level in the return oil sight glass at the lowest position is almost full, stop the pump immediately to clean the temporary filter screen. 3. Repeat step 2; initially, the liquid level will be full in 10 minutes, but this time will gradually increase over time. 4. If the time required for the return oil line to become filled with liquid increases, a hammer can be used to strike the return oil pipe in order to shake out the impurities. 5. It is qualified when there are no hard impurities on the temporary filter screen. Then replace the lubricating oil filter element.

It’s not right to bring all the dirty stuff back into the fuel tank either; as for whether the fuel return is smooth or not, there’s a fuel return sight glass available for monitoring that
