The Elevators Used In Many Places Are Hydraulic Systems, So A Friend Has To Ask Why They All Use Hydraulic Systems? In Fact, The Big Reason Is That He Is Very Environmentally Friendly And Will Not Pollute. Of Course, His Other Characteristic Is That He Has A Large Load And Relatively High Stability. For Example, The Cranes And Excavators We Use Now Have The Application Of Hydraulic System. But We Can't Ignore The Hydraulic System Of The Elevator. He Has Something To Fear. Huake Mechanical Equipment Will Come To Discuss With Us. The Hydraulic System Should Have Good Sealing Performance So As To Prevent The Invasion Of Air And Water, Because The Air Will Oxidize The Hydraulic Oil. If There Is Too Much Air, The Hydraulic System Cannot Operate. Water Will Make The Hydraulic Oil Emulsified, And Then Make The Hydraulic Oil Lose The Ability Of Lubrication, Which Also Makes The Hydraulic Cylinder Wear To A Large Extent, Which Also Reminds Us That If The Hydraulic Oil Emulsified, We Should Replace It In Time. In Fact, Through The Above Introduction, You Should Know That The Lift's Hydraulic System Is Afraid Of Air And Water. If Our Lift Is Used Many Times, Then We Need To See If The Temperature Of The Hydraulic System Will Be Too High, Which Will Also Make The Huake Mechanical Equipment Elevator Unable To Carry Out Normal Operation.
