Information

  There are many ship accessories manufacturers on the market. Nanjing Jingyun ship accessories Co., Ltd. is a professional manufacturer of ship accessories. Recently, many consumers have asked about hand pump. Next Nanjing Jingyun ship accessories Co., Ltd. will introduce the method of breaking up the oil pump in detail.

Because there are many kinds of ship accessories manufacturers, sometimes consumers fail to break up the quality of the oil pump. But as long as we master the following three points, it is easy to make a judgment.
1. Check the technical condition between the oil transfer pump, primary filter and oil tank. When continuously lifting the hand pump to spray the pump oil, the first thing to feel is that the handle has a downward vacuum suction. If it doesn't, but the handle is lifted up, it will feel empty and light. At this time, it is easy to determine that there is a fault, because the fault of the oil circuit is reflected in the oil tank of the reverse transfer pump.
2. Check the technical status of hand oil pump, secondary filter and injection chamber. When continuously pressing the handle of the hand pump to pump oil, you should feel more and more power. On the contrary, if you feel that the handle is pressed down lightly, the fault should be between the oil chamber of the hand pump, the fine filter and the injection pump. If there is no overflow of fuel oil at each pipeline joint, it must be that the pressure limiting ball is worn or the spring of the pressure limiting valve is in the open state, and the fuel oil from the pump returns to the tank through the return pipe.
3. If the hand pump is used continuously for many times, the engine can run, but when the fuel in the oil pump cavity is used up, the engine suddenly stalls again. At this time, we can determine the fault
The focus is on the mechanical oil transfer pump itself. It is necessary to check whether the wear of the piston of the mechanical pump has exceeded the limit, and then check whether the combined wear of the push rod or the push rod roller is very serious. The most important point is to check whether the main spring of the oil transfer pump has broken.
