In order to ensure the safety of the biogas generator set, we will analyze the specific situation of the oil leakage of the biogas generator supercharger:

      1. The pressure at the compressor end of the pressure shell is caused by the accumulation of oil and gas. Check the supercharger and check that the supercharger is a good product. Generally, it can be analyzed from the use of the supercharger. Causing the air filter to block the negative pressure up to 5.5kPa, which will cause the compressor to leak at the compressor end; the car is in the mountainous area, the biogas generator set does not add the throttle at low speed for more than 15 minutes, the supercharger medium pressure impeller The establishment of a vacuum on the back side of the air seal can also cause oil leakage at the compressor end of the supercharger. As long as the air filter is frequently maintained, the idling time of the biogas generator set should not be too long, and this false oil leakage phenomenon can be eliminated.

      2. If the oil pressure is too high, it will cause oil leakage of the supercharger: the high oil pressure of the biogas generator supercharger is also one of the causes of the oil leakage of the supercharger. When we check that the supercharger is a good product and find that the oil pressure of the biogas generator set is much higher than the specification, we must check the lubrication system of the biogas generator set, whether the pressure regulating valve is stuck or malfunctioning, and the biogas power generation The oil pressure of the unit is normal, and the oil leakage of the supercharger can be eliminated.

      3, poor oil return will cause the supercharger oil leakage: the return of the biogas generator supercharger is returned from the supercharger return pipe to the biogas generator set by the self-weight of the oil, if the return pipe appears to be constricted and blocked, The oil return of the supercharger is not smooth, and the supercharger will leak oil at both ends. It should be ruled out that the oil return is not smooth, and the fault is eliminated when the supercharger is in good condition.

       4. The biogas generator set is frequently parked and started during construction: the biogas generator set frequently stops and starts during construction, which will cause the turbine end of the turbocharger intermediate case to coke; at the same time, it will cause the intermediate casing to return to the oil chamber for coking, so that the supercharger return oil chamber is reduced. If the oil return is not smooth, oil leakage will occur. Check whether the consumables are intact and remove the coking.

       5, the biogas generator set suffocation will cause the oil return of the supercharger is not smooth, the supercharger leaks oil: some superchargers found oil leakage or even oil leakage at both ends, after checking the supercharger is a qualified product, oil return The oil is also normal. After dismantling, it is found that there is a thick oil stain in the middle section of the supercharger main shaft. Some of them are hard. After cleaning, the middle section of the main shaft becomes yellowish and the oil in the supercharger return pipe is also oily. From the above phenomenon, it can be judged as The helium gas of the biogas generator set caused the oil return of the supercharger to be poor. Replace the biogas generator set four to eliminate the helium gas from the biogas generator set, and clean the supercharger and return oil pipe, and the fault can be eliminated.
