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

 

在选择电梯平台调速回路时,需要满足调速要求,降低功率损耗.常见的调速回路主要包括:运行调速电路、容积调速回路、容积节流调速电路.节流调速电路功率损耗大,低速稳定性好.容积调速电路无溢流损耗、无节流损耗、效率高、低速稳定性好.

 

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

 

如果要同时满足双方的要求,强冠电梯提示你可以使用变量泵和节流阀的容积节流调速回路的压差式,使节流阀两全压差小,尽量减少压力损失.

 

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

 

举升平台液压油在管路中,会呈现粘性,且粘度过高,会产生较大的内力,引起电梯油发热,同时增加机油阻力活动.当粘度过低时,容易产生泄漏,降低系统容积效率.因此,一般认为粘度适宜,粘度温度较好.此外,当油液在管道中活动时,管道也会受到沿程压力损失和局部压力损失的影响,使管道在减少管道的同时,尽可能地缩短管道.

 

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

 

考虑到平台执行机构工作条件的多样性,有时需要大流量、低压力.有时你需要小流量,高压力.因此,选择压力限制型变量泵是因为这种泵的流量随系统压力的变化而变化.

 

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

 

当系统压力降低时,流量较大,可以满足执行机构的快速行程.当系统压力上升时,流量减小,可以满足执行机构的工作计划.这可以满足执行机构的工作要求,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

 

在使用升降电梯时,有时不能贪图省超负荷运行设备,这样只会降低操作速度和损坏设备,增加排放,影响下一次,缩短电梯平台的使用寿命.

 

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
