Hydraulic Jacks Lifting operation, we should choose the appropriate tonnage of hydraulic jack: load-bearing capacity can not be overloaded, the choice of hydraulic jack load-bearing capacity needs to be greater than 1.2 times the weight of gravity; the minimum height of hydraulic jack is appropriate, in order to facilitate removal, the minimum height of hydraulic [...]
How to operate the hydraulic jack correctly when adjusting the speed? Hydraulic Jack must adjust its speed correctly in application. Only in this way can its performance be fully embodied. Then how should we operate correctly? The following points are elaborated in detail for you: In the process of debugging, the buffer device should be [...]
In engineering operation, engineering hydraulic jack is a kind of lifting equipment, unlike electric hoist, which lifts all kinds of materials by tension, while electric hoist lifts all kinds of materials. Take hydraulic jack as an example, before using, we must check whether the reserved hole is unblocked, whether the steel strand is rusted or [...]
Fault Diagnosis of Hydraulic Cylinder : the causes and treatment methods of hydraulic cylinder misoperation or malfunction are as follows: (1) The spool is stuck or the valve hole is blocked. When the flow valve or directional valve spool is stuck or the valve hole is blocked, the hydraulic cylinder is prone to malfunction or [...]
The structure of hydraulic cylinders are various, and their classification methods are also various: according to the movement mode, it can be divided into linear reciprocating motion and rotary swing hydraulic cylinder; according to the action of hydraulic pressure, it can be divided into single-acting hydraulic cylinder and double-acting hydraulic cylinder; according to the structure [...]
Classification of Hydraulic Jacks Hydraulic jacks are divided into: general hydraulic jacks and special hydraulic jacks. The universal hydraulic jack is suitable for all kinds of lifting operations with low lifting height. It consists of oil chamber, oil pump, oil storage chamber, piston, rocker, oil valve and other major parts. When working, as long as [...]
Maintenance of Hydraulic Cylinders When the hydraulic jack is used, the bottom should be flat and tough. Oil-free wood panels to expand the pressure surface for safety. It is not possible to replace the board with iron plates to prevent slipping. It is required to be stable when lifting, and it is necessary to check [...]
Precautions for Hydraulic Jack If there is a gap in the use, you can loosen the oil drain screw on the pump body, and then open the pump body vertically down a few times, then tighten the oil drain screw to continue using. When using hydraulic jacks, no eccentric load or overload shall be added [...]
Before use, it is necessary to check whether the parts are normal. Check whether the piston, joint, high-pressure hose, etc. are leaking oil. When using, the provisions of the main parameters should be strictly observed. Avoid excessive overload. Otherwise, when the lifting height or lifting tonnage exceeds the specified level, serious oil leakage will occur [...]
