1、節(jié)流閥裝在回油路上，回油路上有較大的背壓，因此在外界負(fù)載變化時酸沖作用，升降機(jī)運(yùn)動的平穩(wěn)性比進(jìn)油節(jié)流調(diào)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、回油節(jié)流調(diào)速回路中，經(jīng)升降機(jī)節(jié)流閥后壓力損耗而發(fā)熱，導(dǎo)致溫度升高的油融流回油箱，容易散熱。
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、回油節(jié)流調(diào)速回路廣泛應(yīng)用于功率不大、負(fù)載變化較大或運(yùn)動平穩(wěn)性融高的液壓系統(tǒng)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.
