重慶升降機液壓油流經各類液壓閥時不可避免的存在著壓力損失和流量損失，這一部分的能量損失在全部能量損失中占有較大的比重。因此，合理選擇液壓器，調整壓力閥的壓力也是降低功率損失的一個重要方面。流量閥按系統中流量調節范圍選取并保證其最小穩定流量能滿足使用要求，壓力閥的壓力在滿足液壓設備正常工作的情況下，盡量取較低的壓力。
Ningbo lifting platform inevitably exist when the lifting platform hydraulic oil flows through the various types of hydraulic valve pressure loss and flow losses, the loss of energy in this part of the large proportion in the total energy loss. Therefore, a reasonable choice of a hydraulic device, the pressure adjusting valve is also an important aspect of power loss reduction. Flow valve flow adjustment range by selecting the system and ensure steady flow to meet the minimum requirements, the pressure valve in case of hydraulic equipment to meet the work, and try to get a lower pressure.

升降平臺液壓油在管路中流動時，將呈現出黏性，而黏性過高時，將產生較大的內摩擦力，造成油液發熱，同時增加油液流動時的阻力。當黏性過低時，易造成泄漏，將降低系統容積效率，因此，一般選擇黏度適宜且黏溫特性比較好的油液。
Ningbo lifting platform hydraulic oil flow in the pipeline, will appear in viscosity, while viscosity is too high, will have a greater internal friction, resulting in heating oil, while increasing the resistance to fluid flow in. When the viscosity is too low, could easily lead to leaks, will reduce the volumetric efficiency of the system, therefore, generally select the appropriate viscosity and good viscosity-temperature characteristics of the oil.

升降平臺當油液在管路中流動時，還存在著沿程壓力損失和局部壓力損失，因此設計管路時盡量縮短管道，同時減少彎管。電壓不穩定會燒壞操作箱里面的各類電器元件，是升降平臺設備無法收到控制，其次是頻繁的電壓不穩定會直接燒壞動力單元中的電機，電機燒毀導致的后果是非常嚴重的，會導致壓力瞬間降低，如果升降設備沒有安裝溢流閥或者防爆閥等安全設備，會導致升降設備下墜，導致事故的發生。
Ningbo lifting platform when the oil flow in the pipeline, there is also pressure loss along the way, and local pressure loss, so try to shorten the pipeline when the pipeline design, while reducing elbow. Operating voltage instability will burn all kinds of electrical components inside the box, the device can not receive control lifting platform, followed by frequent voltage instability will directly burn the motor power unit, the motor burned consequences are very serious cause will lead to reduced pressure moment, if there is no lifting equipment explosion relief valve or other safety equipment installation can cause lifting equipment to fall, resulting in accidents.
