回油节流调速回路的优点

1、节流阀装在回油路上，回油路上有较大的背压，因此在外界负载变化时酸冲作用，升降机运动的平稳性比进油节流调速回路要好。
Speaking throttle lift factory installed oil back on the road, on the way back to the oil has a larger back pressure, so when the external load changes acid thrusting, smooth movement than lift oil into better control Circuits.

2、回油节流调速回路中，经升降机节流阀后压力损耗而发热，导致温度升高的油融流回油箱，容易散热。
Lift manufacturers introduce meter-speed circuit, after the lift throttle pressure loss and fever, leading to melting temperature of the oil back into the tank, easy to heat.

3、回油节流调速回路广泛应用于功率不大、负载变化较大或运动平稳性融高的液压系统中。
Lift manufacturers remind meter-speed circuits are widely used in power little bigger load changes or movement of the hydraulic system of high melt stability.
