Why does the hydraulic pump station rise to the top position, the engine is loaded, and black smoke comes out from the exhaust pipe of the pump station? What is the situation? In the case of this phenomenon, the first step is to determine whether the overflow valve is installed or not, and whether the system pressure can be automatically reduced.
In this case, the pressure of the hydraulic pumping station system is too high, there is no overflow valve installed, or it has been damaged, resulting in the pressure drop of the hydraulic pumping station system. Otherwise, this situation will not occur. Serious problems will lead to hidden dangers of explosion in the hydraulic pump station system. Therefore, the hydraulic pump station system must be maintained regularly.
If the electro-hydraulic servo valve and the washboard of the servo valve are used in the ultra-high pressure hydraulic pumping station, the oil should flow from the oil supply pipeline to the collector and return directly to the oil tank, so that the oil can be circulated repeatedly to flush the system, so that the solid particles can be filtered out by the oil. During the flushing process, the oil filter should be checked every 1-2 hours at Huibo ultra-high pressure hydraulic pumping station in Henan Province. In order to prevent the oil filter from being blocked by pollutants, the bypass should not be opened at this time. If it is found that the oil filter is blocked, the oil filter should be changed immediately and carefully maintained.
