When buy, a lot of people care the price only, and the service that ignores product quality and service life and product later period, because of incorrect understanding, and him short of of hydraulic pressure plane shear that buys likely use requirement and fixed number of year, when buying so, should have done the following these maintaining: (1) the viscosity that hydraulic pressure plane shear should maintain proper. Viscosity is the size of obstruction of the attrition between the element when stating oily current is moved. The meeting when viscosity is too big increases pipeline to carry instruction mediumly, loss of the energy in working process increases, lead plane sky carries a loss to increase, temperature rise is sharp and working temperature is high, in advocate end of pump oil absorption may appear phenomenon of " cavity " ; Oily viscosity of plane shear hydraulic pressure passes the lubricant requirement with hour of unwarrantable good plane shear, of component of system of hydraulic pressure of aggravate plane shear wear away and systematic leak raises, cause efficiency of oil pump cubage to drop. Specific actuating pressure of system of plane shear hydraulic pressure is inspected when using, working temperature is decided with speed of executive component motion. The appropriate of high pressure, high temperature chooses tall viscosity, the appropriate that high speed moves chooses low viscosity. (2) oil of hydraulic pressure of hydraulic pressure plane shear should have good anti-wear properties and lubricity. The purpose depends on reducing mechanical attrition, assure the service life of system of plane shear hydraulic pressure. (3) oil of hydraulic pressure of hydraulic pressure plane shear sticks lukewarm sex goodly. Sticking lukewarm sex is to show oily fluid viscosity raises the rate that falls to follow temperature and change, express with viscosity index normally. Viscosity index is older, oily fluid viscosity lifts along with temperature in work of system of plane shear hydraulic pressure drop smaller, make thereby of hydraulic pressure system inside leak has not been sent big. ) the exercise operating mode of system of plane shear hydraulic pressure is general relatively abominable, oily temperature of the hydraulic pressure in exercise process changes along with load and environmental temperature, viscosity index is not gotten commonly under 90. (4) oil fights hydraulic pressure plane shear goodly oxidation invariability. Fighting oxidation invariability is temperature pointing to oil when lifting low fight the ability that reacts with the chemistry since the content that contain oxygen. Practice makes clear, oily Wen Meisheng is tall 10 ℃ , its chemistry reacts rate rises about one times. Fight the oil of plane shear hydraulic pressure with oxidation good invariability to use metamorphism of not easy oxidation for long, can assure the normal circulation of hydraulic pressure oil. Hydraulic pressure plane shear often must keep clean, the part that did not paint is antirust grease, do plane shear of good hydraulic pressure maintain the job just can prolong service life so.
