Hydraulic system widely applies to double chuck lathe, which consists of oil pump, hydraulic cylinder, hydraulic valve, attachment and hydraulic oil.
The oil country lathe is centralized controlled by hydraulic station, which is also called hydraulic pump. The form of hydraulic pump is variable pump.
The variable pump is with distinct advantages.
a) It discharges large quantity of oil and consumes little at the same time.
b) It emits such little heat when in working condition that prolongs the service life of equipment parts.
c) It is environment friendly.
Lubrication equipment of pipe threading lathe is cyclonic pump, which is with high stability and low cost.
Spindle of screw machining lathe is lubricated by hydraulic oil, which assembles the features of anti-abrasion, anti corrosion and cooling down.
Overflow valve is the protective device of screw cutting lathe, which is for stabilizing voltage, prevent overflow and protect the whole system
Two reversing valves: WE-3C4-02-G-D2-30, WE-3C4-02-G-D2-30, which are for linking, cutting off, reversing of hydraulic oil, are with
