1、重慶升降機液壓泵站吸入量不足，原因是吸油管路上的流量阻力過大或補油量不足。如泵的轉向，油箱中液面過低，油溫過箍，進油管漏氣、濾油器堵塞等。
Zhejiang Lifts inadequate intake volume of the hydraulic pump station, because the flow resistance of suction piping is too large or fill fuel shortage. Steering pump, tank liquid level is too low, the oil temperature is too hoop, into the pipeline leak, oil filter blockage.

2、液壓泵站泄漏量過大，原因是間隙過大，密封不良造成。如配油盤被金屬碎片、鐵屑等劃傷，端面漏油大大增加，變量機構中單向閥密封面配合不好，泵體和配油盤的支承面有砂眼或裂痕等。這可以檢查泵體內液壓油中混雜的異物，未判斷泵中被損壞的部位。
Zhejiang Lifts pump station leak is excessive, because the gap is too large, resulting in poor sealing. As with the oil pan is metal fragments, iron and other scratches, end leakage greatly increased variable mechanism with the bad check valve sealing surface, the bearing surface of the pump and oil pan with trachoma or cracks and the like. You can check the hydraulic oil in the pump body mixed foreign matter, did not determine the damaged parts of the pump.

3、當液壓泵站配油盤與泵體之間沒有貼緊而造成大量泄漏，則應拆開液壓泵重新組裝，如油液粘度過低，使各部分泄漏增加，要更換液壓油。
When there is no snapping Zhejiang freight between the oil pan and pump station pump and cause a lot of leakage, you should re-open the hydraulic pump assembly, such as the oil viscosity is too low, so that all parts increased leakage,to replace the hydraulic oil.

4、液壓泵站傾斜盤實際傾角太小，使泵的排量小，這需要控制操縱桿，增加斜盤傾角。 
Zhejiang Lifts actual angle swashplate pump station is too small, the pump displacement is small, it is necessary to control the joystick, the swash plate angle increases.

5、液壓泵站壓盤損壞，當柱塞泵處于自吸狀態下工作時，壓盤損壞，泵無法自吸，沒有流量輸出，應更換壓盤。
Zhejiang Lifts pump station platen damage, when the self-priming piston pump in working condition, the pressure plate is damaged, the pump can not self-priming, no flow output, replace the platen.
