How can prolong the service life of hydraulic shearing machine

(1) hydraulic shearing machine to maintain proper viscosity. Viscosity is the Intermolecular friction resistance when the size of the oil flow. Stick spent big Shi will increased pipeline in the of conveying resistance, work process in the energy loss increased, host no-load loss increased, temperature rose fast and work temperature high, in main pump sucking oil end may appeared "hole" phenomenon; cut Board machine hydraulic oil stick spent hours is cannot guarantee cut Board machine good of lubrication conditions, increased cut Board machine hydraulic system parts of wear and system leak increased, caused pump volume efficiency declined. Specific time of shearing machine hydraulic system pressure, operating temperature and actuator velocity may be. Suitable for high viscosity of high pressure, high temperature, low viscosity high speed should be chosen.

(2) hydraulic shears, hydraulic oil has good abrasion resistance and lubricity. To reduce mechanical friction, ensuring the life of shearing machine hydraulic system.

(3) good viscosity-temperature hydraulic oil for hydraulic shears. Viscosity-temperature means lifting oil viscosity changes with the temperature level, usually represented by a viscosity index. Viscosity index greater shearing machine hydraulic system oil viscosity with temperature rising in the smaller, so that the leakage of the hydraulic system is not too large. ) Job of shearing machine hydraulic system conditions are generally more severe, jobs such as hydraulic oil temperature changes with the load and the ambient temperature, viscosity index not lower than 90.

(4) good oxidation stability of hydraulic shear engine oil. Oxidation stability means oil temperature is low ability to react with oxygen. Practice shows that a rise in oil temperature 10 ℃, the rate increases by about 1 time a chemical reaction times. Good oxidation stability of shearing machine hydraulic oil used for a long time is not easy to oxidation, can ensure normal circulation of hydraulic oil.
