When hydraulic oil flows through various hydraulic valves, pressure loss and flow loss are inevitable This part of the loss accounts for a large part of the total loss Therefore, reasonable selection of hydraulic valve is also an important aspect of reducing power loss The range of flow control valve is selected according to the system and the stability of small flow can meet the use requirements. When the pressure valve of hydraulic lifting platform works normally, try to obtain a lower pressure value

 

在選擇電梯平臺調速回路時,需要滿足調速要求,降低功率損耗.常見的調速回路主要包括:運行調速電路、容積調速回路、容積節(jié)流調速電路.節(jié)流調速電路功率損耗大,低速穩(wěn)定性好.容積調速電路無溢流損耗、無節(jié)流損耗、效率高、低速穩(wěn)定性好.

 

When selecting the elevator platform speed regulation circuit, it is necessary to meet the speed regulation requirements and reduce power loss Common speed regulating circuits mainly include: operation speed regulating circuit, volume speed regulating circuit and volume throttling speed regulating circuit The throttle speed regulation circuit has large power loss and good low-speed stability The volume speed regulation circuit has no overflow loss, no throttling loss, high efficiency and good low-speed stability

 

如果要同時滿足雙方的要求,強冠電梯提示你可以使用變量泵和節(jié)流閥的容積節(jié)流調速回路的壓差式,使節(jié)流閥兩全壓差小,盡量減少壓力損失.

 

If you want to meet the requirements of both sides at the same time, qiangguan elevator suggests that you can use the differential pressure type of volume throttling speed regulating circuit of variable displacement pump and throttle valve to reduce the total differential pressure between the two throttle valves and minimize the pressure loss

 

舉升平臺液壓油在管路中,會呈現(xiàn)粘性,且粘度過高,會產(chǎn)生較大的內力,引起電梯油發(fā)熱,同時增加機油阻力活動.當粘度過低時,容易產(chǎn)生泄漏,降低系統(tǒng)容積效率.因此,一般認為粘度適宜,粘度溫度較好.此外,當油液在管道中活動時,管道也會受到沿程壓力損失和局部壓力損失的影響,使管道在減少管道的同時,盡可能地縮短管道.

 

The hydraulic oil of the lifting platform will show viscosity in the pipeline, and the viscosity is too high, which will produce large internal force, cause the elevator oil to heat, and increase the resistance activity of the oil at the same time When the viscosity is too low, it is easy to produce leakage and reduce the volumetric efficiency of the system Therefore, it is generally considered that the viscosity is appropriate and the viscosity temperature is better In addition, when the oil moves in the pipeline, the pipeline will also be affected by the pressure loss along the way and local pressure loss, so as to shorten the pipeline as much as possible while reducing the pipeline

 

考慮到平臺執(zhí)行機構工作條件的多樣性,有時需要大流量、低壓力.有時你需要小流量,高壓力.因此,選擇壓力限制型變量泵是因為這種泵的流量隨系統(tǒng)壓力的變化而變化.

 

Considering the diversity of working conditions of platform actuator, large flow and low pressure are sometimes required Sometimes you need small flow and high pressure Therefore, the pressure limited variable displacement pump is selected because the flow of this pump changes with the change of system pressure

 

當系統(tǒng)壓力降低時,流量較大,可以滿足執(zhí)行機構的快速行程.當系統(tǒng)壓力上升時,流量減小,可以滿足執(zhí)行機構的工作計劃.這可以滿足執(zhí)行機構的工作要求,功耗更合理.

 

When the system pressure decreases, the flow is large, which can meet the fast stroke of the actuator When the system pressure rises, the flow decreases, which can meet the work plan of the actuator This can meet the working requirements of the actuator, and the power consumption is more reasonable

 

在使用升降電梯時,有時不能貪圖省超負荷運行設備,這樣只會降低操作速度和損壞設備,增加排放,影響下一次,縮短電梯平臺的使用壽命.

 

When using the elevator, sometimes we can't save the overload operation equipment, which will only reduce the operation speed and damage the equipment, increase the emission, affect the next time and shorten the service life of the elevator platform
