What is the performance and special use of hydraulic jack self locking device? Under what working condition is hydraulic jack self-locking device used? The self-locking jack is used for the place where the heavy object needs to be maintained for a long time. It can still support the heavy object on the ground after the [...]
How to maintain the hydraulic jack? The hydraulic jack usually needs to use anti-wear hydraulic oil when working, and the hydraulic oil filled into the oil tank must be filtered. Usually, it is filtered once a month when it is used. The oil tank should be washed regularly. The oil level in the oil tank [...]
Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized, otherwise, when the oil pipe joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be ejected rapidly. When the hydraulic circuit is depressurized, first loosen the hand wheel or high-pressure screw at the overflow valve to unload the pressure [...]
The hydraulic cylinder plays an important role in lifting, pushing and supporting objects. The precautions for using the hydraulic cylinder are listed as follows: 1. During the use of the hydraulic cylinder, the hydraulic oil shall be replaced regularly, and the filter screen of the system shall be cleaned to ensure its cleanness, so as [...]
In the working process of hydraulic cylinder, in order to prevent the two pairs of pistons from squeezing the cylinder head, causing noise, affecting the accuracy of the workpiece and even damaging the parts, buffer devices are often equipped at both ends of the cylinder in the system of hydraulic pump station. Its function is [...]
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 [...]
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 [...]
