引起重慶升降平臺油溫過高的原因很多，歸納起來主要有以下兩點。There are many reasons causing high temperature Chongqing lifting platform, summed up in the following two points.

1.設計不當。包括重慶升降平臺系統中沒有卸荷回路；油箱儲油量太小，致使油液循環太快，冷卻器冷卻作用差，且高負荷 長時工作；液壓元件選用不當、管路設計不合理及運動元件機械摩擦產生的熱量等。Improper design. Including Chongqing lifting platform in the system without unloading circuit; the oil tank is too small, resulting in oil cycle too fast, the cooler cooling effect is poor, and the high load working for long time; the improper selection of hydraulic components, piping design unreasonable and mechanical motion components of friction heat.

2.使用不當。包括誤用粘度太大的油液，引起液壓損失過大；液壓系統混入空氣，磨粒、雜質等被吸附在過濾器的濾芯上；液壓油箱內油位過低；重慶升降平臺液壓油冷卻循環系統工作環境溫度過高等。Improper use. Including the misuse of oil viscosity is too large, causing the hydraulic loss is too large; the air mixed with the hydraulic system, abrasive and other impurities are adsorbed on the filter cartridge; the hydraulic oil in the oil level is too low; Chongqing lifting platform hydraulic oil cooling system working environment temperature is too high.
