facade embossing machineIs to rely on hydraulic oil to transfer kinetic energy, hydraulic oil selection is correct or not directly related to the performance of the facade embossing machine play.
Select hydraulic oil, accordingsteel wooden door embossing machineThe system pressure, the working environment of the facade embossing machine, the temperature, the choice of different types of hydraulic oil.
Hydraulic oil is divided into different components of additives added in the base oil.General purpose hydraulic oil，antiwear hydraulic oil，Guide rail hydraulic oil，low temperature hydraulic oilWait. If the system pressure in the hydraulic press is less than 7Mpa, HL type general hydraulic oil is generally selected. if the hydraulic press uses plunger pump or vane pump as the power source, and the pressure of the system is medium, high pressure and heavy load, the hydraulic oil selected in the system should be HM type anti-wear hydraulic oil, so as to ensure the normal operation of fine parts in the nutrition system, if the ambient temperature is below zero low temperature occasions should choose HS type low temperature hydraulic oil. HV type low temperature hydraulic oil is used in lower environmental occasions than HS type low temperature hydraulic oil.
Even the same type of hydraulic oil, steel wooden door embossing machine in different ambient temperature, should also choose different viscosity of hydraulic oil. Dynamic viscosity is an indicator of the fluidity of hydraulic oil. Dynamic viscosity: is the force required to produce a unit flow rate using a unit area of liquid layer per unit distance. Unit: pa.s (pa per second). Kinematic viscosity: that is, the ratio of dynamic viscosity to density, the customary unit is: centistokes. The smaller the dynamic viscosity, the better the low-temperature fluidity. L-HM32, L-HM46, L-HM68 these three kinds of anti-wear hydraulic oil is more commonly used models.
The suitable working temperature of hydraulic oil is 20-60 degrees. The steel wooden door embossing machine produced by Baixing in Tengzhou is equipped with a water-cooled cooler device in the oil tank. When the hydraulic machine works, the cooling device is automatically turned on by the temperature measuring device so as to achieve the function of automatic control of oil temperature. Therefore, Baixing hydraulic press generally uses L-HM46 anti-wear hydraulic oil as the four seasons hydraulic oil.
