1、检查液压升降平台http://www.rgsjpt.com/油箱液面是否达标准值，进油管口是否始终低于液面，解决方法向油箱加油。
Check the hydraulic lift platform tank level is reached the standard value, inlet pipe mouth is always lower than the level, the solution to the fuel tank.
　　
2、液压升降平台齿轮泵噪声过大，首先要从外部检查，检查油管、泵的安装架，机架是否松动，若有松动，必须固紧，否则将产生共振。
Hydraulic lifting platform gear pump noise is too large, from the first external examination, checking the tubing, pump mounting brackets, the rack is loose, if loose, must be tightened, otherwise it will resonate.
　　
3、检查液压升降平台齿轮泵进油管路的过滤器上是否有脏物，堵塞而产生气穴，排除方法是用油冲洗脏物。
Check the hydraulic lifting platform if there is dirt on the gear pump inlet line filter clogging cavitation, Remedy is flush with oil dirt.
　　
4、从液压升降平台泵轴密封处或泵体泵盖接合处渗入空气，解决方法更换油封或纸垫。
From hydraulic lifting platform or pump shaft seal joints penetrate air pump cover, Solution Replace seals or paper pad.
　　
5、液压升降平台http://www.rgsjpt.com/齿轮泵进油管中有无空气，可通过仔细听运转部分的声音来鉴别，在结合部加一点油，若声音变小，说明此处密封不好，漏气，解决方法拧紧接头或更换衬垫，密封圈和接头等部件。
Hydraulic lifting platform gear pump inlet pipe in the presence or absence of air, can be identified by carefully listening to the sound of moving parts, add a little oil in a combined unit, if the sound becomes smaller, indicating where the seal is not good, leakage, tighten the fitting or workaround replace gaskets, seals and fittings and other components.
