Whether it is to buy imported vacuum pump or domestic vacuum pump, after using for a period of time, there will always be oil leakage of vacuum pump. What is the cause of this? The problem of oil leakage is very troublesome, because the oil leakage first pollutes the use environment, the second is the waste of vacuum pump oil, which needs to be continuously added with new oil; third, it is likely to cause problems with the vacuum pump. If the oil leakage is not found in time, resulting in no vacuum pump oil in the vacuum pump (less than the oil required for normal operation), this is very easy to cause failure It will increase the economic cost. In fact, for this problem, let's take a look at the solution of vacuum pump oil leakage!

1. When used in the environment with high temperature conditions, oil leakage may occur at the interface of vacuum pump oil circuit. This phenomenon is actually the simplest and best treatment problem. We can re glue and seal the oil pipe after shutdown and find out the location of oil leakage.

2. If you can't find any oil leakage, it will be very troublesome. Because there are many places for vacuum pump to be sealed, there may be oil leakage in every place. We only see oil leakage on the ground every time, but we can't see oil leakage on the surface. At this time, we need to thoroughly check the oil path outside the vacuum pump, because sometimes there is oil leakage When there are small cracks and holes on the pipe, it is very difficult for us to find out when the vacuum pump is not running. Because the internal pressure and external pressure of the vacuum pump are different during the operation, the pressure difference causes the vacuum pump oil to leak. However, when the vacuum pump is not running, there is no problem. This is the most common problem. (this phenomenon is to observe when switching on / off the machine.)

3. Sometimes the oil we see doesn't leak out, but it comes out from the exhaust port. At this time, we have to watch whether there is any future or smoke when we start the engine. This situation may occur after adding new oil, because most of the time, the customer does not know the amount of oil to be filled, and they always pour oil into it, thinking that there is no overflow, so there is no problem In fact, it's not. When we add new oil, we need to look at the position of the oil sight glass. Generally, when we add new oil, we can not pour oil into the oil. However, the customer asks the oil to pass through the oil sight glass. In this way, when the vacuum pump oil is too full, it will eject or flow out from the exhaust port, because the oil mist separator recovers the oil from the vacuum pump Limited, it is impossible to fully absorb in use, so in this case, it is necessary to open the oil port to drain part of the oil, so that no oil can be seen on the ground.

4. The most troublesome problem is the vacuum pump internal problems. For example, if the oil seal or check valve is broken, the vacuum pump will also have the phenomenon of oil injection and oil return. Due to the return of oil, the vacuum pump oil will return through the suction port, which will pollute the gas we pump or other things at the suction port, causing unnecessary economic losses. At this time, we need to dismantle the machine for replacement, if you can do it yourself Replacement is the best, if not, please ask the manufacturer to replace.

These are the most common problems of oil leakage. Sometimes, problems such as fuel injection and oil leakage may occur due to our use environment and other parts of the vacuum pump. When you are unable to determine the problems and solutions by yourself, it is your best choice to find a professional vacuum pump maintenance manufacturer.
