In this paper the commonly used mechanical and hydraulic system for the maintenance of undeserved cause harm, the paper discusses how to properly maintained hydraulic system.
The mechanical engineering hydraulics is concerned, the normal operation of the hydraulic system is one of the main technical conditions. The hydraulic oil is qualified to ensure reliable operation of the hydraulic system, correct and reliable operation of the hydraulic system maintenance is the fundamental. Therefore, I generally work practice, according to the working environment of the hydraulic system of engineering machinery maintenance a rough.
1 choice for the hydraulic oil
The hydraulic oil in hydraulic system plays a relay pressure, lubrication and cooling, sealing, hydraulic oil is not appropriate selection of hydraulic system failure and the durability of the early decline. According to the instructions of random selection of brand stipulated in the hydraulic oil, special circumstances to use for fuel, should strive to its performance with the same grade performance. Different type of hydraulic oil mixed use, can prevent the hydraulic oil chemistry, performance change. Brown, ivory, smell of hydraulic oil is metamorphic oil, cannot use.
5.31000 h examination maintenance
Cleaning, cleaning cartridge filter, replace hydraulic pressure tank, replace hydraulic oil. Long time to replace the oil temperature homework properly in advance. Of course, if can be analyzed by oil testing to guide in oil is the most economic,
But want to notice extended use of oil, should be inspected once every 100h, in order to find out and replace metamorphic oil.
5.47000 h and 10000h examination maintenance
Hydraulic system by professionals, to make necessary adjustment and maintenance. According to the practice of imported hydraulic pump and hydraulic pressure motor, 10000h after work, or to overhaul repair for pump and motor can damage, for hydraulic system of life is to destroy.
