1、重庆升降机液压泵站吸入量不足，原因是吸油管路上的流量阻力过大或补油量不足。如泵的转向，油箱中液面过低，油温过箍，进油管漏气、滤油器堵塞等。
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、液压泵站泄漏量过大，原因是间隙过大，密封不良造成。如配油盘被金属碎片、铁屑等划伤，端面漏油大大增加，变量机构中单向阀密封面配合不好，泵体和配油盘的支承面有砂眼或裂痕等。这可以检查泵体内液压油中混杂的异物，未判断泵中被损坏的部位。
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、当液压泵站配油盘与泵体之间没有贴紧而造成大量泄漏，则应拆开液压泵重新组装，如油液粘度过低，使各部分泄漏增加，要更换液压油。
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、液压泵站倾斜盘实际倾角太小，使泵的排量小，这需要控制操纵杆，增加斜盘倾角。 
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、液压泵站压盘损坏，当柱塞泵处于自吸状态下工作时，压盘损坏，泵无法自吸，没有流量输出，应更换压盘。
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.
