Hydraulic components such as pump motor can be used for -60 degree
You can. 60 degrees below zero at low temperatures using hydraulic equipment, hydraulic equipment need to preheat, bare of hydraulic equipment can't work in such a low temperature, the hydraulic workspace, for heat insulation equipment, to meet minimum working temperature operation equipment, can be considered here is applied to the hydraulic equipment itself will generate heat, this feature. Reduce the cost of heating equipment. First under low temperature, the hydraulic oil as working medium were tested first, commonly used hydraulic oil, temperature - 10-90 ℃ with L - HH, L, L - HM HL hydraulic oil, common market models of gear pump, vane pump, plunger pump, the working oil temperature generally 15 to 60 ℃, common types of hydraulic motor market, working oil temperature is generally 10-80 ℃.
How much below zero depends on what type of hydraulic oil, the engine, and the motor can work.
The pump can only be used for the plunger pump, and the gear pump can't be so low. Slide valve type commutator valve is also not available, the valve body and the valve core are different, and the clearance will vary, not reliably, and should be used with the electromagnetic ball valve. The hydraulic oil must be heated, otherwise the viscosity will be too high and the pump will be empty. The military standard is minus 40 degrees, and the 60-degree requirement is relatively rare.
First of all, at low temperature, the hydraulic oil is the first test of the medium, Commonly used hydraulic oil, temperature - 10-90 ℃ with L - HH, L, L - HM HL hydraulic oil, Common market models of gear pump, vane pump, plunger pump, working oil temperature 15 to 60 ℃ in general Common types of hydraulic motor market, working oil temperature generally 10-80 ℃, If you need to 60 degrees below zero at low temperatures using hydraulic equipment, the need for hydraulic equipment preheating, bare of hydraulic equipment can't work in such a low temperature, the hydraulic workspace, for heat insulation equipment, to meet minimum working temperature operation equipment, can be considered here applied to the hydraulic equipment itself will generate heat, this feature.

Hydraulic component: a complete hydraulic system consists of five parts: the power component, the actuator, the control element, the auxiliary element and the hydraulic oil. A complete hydraulic system consists of five parts: the power component, the actuator, the control component, the auxiliary element and the hydraulic oil. The role of the hydraulic element: the element is the prime mover can convert the mechanical energy of liquid pressure, refers to the oil pump in the hydraulic system, it supplies power to the entire hydraulic system. "Motor" : for the transliteration of English motor, namely motor, engine. The principle of work is to turn the rotor of the rotor with the electromagnetism, and the small gear on the rotor wheels the engine flywheel.
