Pressure tank in the work at any time to pay attention to the pressure of the tank, the pressure must be maintained in the random “operation manual” within the scope of the provisions. Insufficient pressure is too low, the oil pump oil absorption is easy damaged, pressure is too high, can make the hydraulic system leak, easy to cause low pressure oil pipe, on the equipment after maintenance and oil change, after all systems in the air, according to the operation instruction handbook “random check the oil level prescribed by the state, the machine stops in the flat place, 15 min after the engine flameout to check the oil level, shall be added if necessary.
Other considerations for hydraulic lifts
In operation to prevent flying stones hit the hydraulic cylinder, piston rod, hydraulic tubing and other parts. If there is a small point on the piston rod, it is necessary to promptly use a stone to grind the edge around the small point, in order to prevent damage to the piston rod sealing device, in the case of no oil leakage can continue to use. Continuous stop in more than 24 hours of equipment, again understand, to the hydraulic pump oil, to prevent the hydraulic pump dry wear and damage. Notes for regular maintenance of hydraulic lift.
At present, some construction machinery hydraulic system can only set the device, the device on the hydraulic system some hidden danger warning function, but the scope and extent of its monitoring has certain limitations, so the hydraulic system inspection and maintenance should be only device monitoring results combined with regular inspection and maintenance.
