Single Post Car Lifts Good Technical Condition

Single Post Car Lifts Good technical condition

For mechanized construction enterprises, the good condition of engineering machinery is the direct factor for the normal production of enterprises. The normal operation of hydraulic system is a key symbol of its good technical condition. Qualified hydraulic oil is the guarantee of reliable operation of hydraulic system, and proper maintenance is the basic of reliable operation of hydraulic system. In this paper, the maintenance of hydraulic system of engineering machinery in general operation environment is discussed.

Select suitable hydraulic oil

Hydraulic oil is used in hydraulic system to transfer pressure, lubrication, cooling and sealing, and the selection of hydraulic oil is the main reason for the early failure and durability of hydraulic system. The hydraulic oil should be selected according to the number specified in the "instruction manual". In particular, the performance should be the same as that of the original brand. The hydraulic oil of different brand number can not be mixed to use, in case the hydraulic oil produces chemical reaction, the property changes. Dark brown, milky white, smelly hydraulic oil is bad oil, cannot be used.

Prevent solid impurities from mixing into hydraulic systems

Clean hydraulic oil is the life of hydraulic system. The hydraulic system has many precision occasionally, some have damping holes, some have gaps and so on. If the solid impurity intrusion will cause the precision coupling strain, the hair card, the oil channel blockage etc., endanger the safe operation of the hydraulic system. The way of the solid impurities to invade the hydraulic system is: hydraulic oil is impure; The tools are not clean. Refueling and maintenance; Hydraulic element debits and so on. The solid impurity intrusion system can be prevented from the following aspects:

Come on in

Hydraulic oil must be filtered and filled, and the tools should be reliable and clean. You can't remove the filter from the fuel tank to improve the speed of the fuel. Refueling personnel should use clean gloves and overalls to prevent solid impurities and fiber impurities from falling into the oil. When the maintenance

Remove the oil tank cover, filter cover, test hole, hydraulic tubing and other parts, so as to avoid the dust when the system oil channel is exposed, the parts should be cleaned thoroughly before opening. Such as removing the hydraulic tank of fuel cap, remove the cap around the soil, loosen the cap, remove residual impurities in the joint area (not rinse in order to avoid water seeping into the tank), confirmed after cleaning to open the cap. When wiping material and hammer should be used, it should choose not to remove the fiber impurities and hit the special hammer with rubber. Hydraulic components, hydraulic hose should be cleaned carefully, with high pressure wind blow dry and assembly. Choose a well-packed genuine filter element (internal packing is damaged, although the filter element is in good condition, it may not be clean). Clean the filter at the same time when changing the oil and apply the wiping material before installing the filter to carefully clean the bottom of the filter shell.
