Electro-hydraulic jacks feature large output, light weight, and long-range operation. Various types of operations such as top, push, pull, and squeeze can be realized. Electro-hydraulic jacks are widely used in various industries such as transportation, railways, bridges, shipbuilding, etc. In recent years, they have been obtained in foundation settlement tests and static pressure piles. Wide range of applications. Today Xiao Bian will introduce to you the use of electric hydraulic jacks, troubleshooting methods and precautions.
Electric hydraulic jack method of use
1. If the pump has insufficient oil, it is necessary to add working oil (10# oil) to the pump before it can work.
2, estimate the weight, avoid overloaded use.
3. Determine the center of gravity of the lifting gear, select the jack to focus on, and at the same time must consider whether the floor is soft and hard and whether it is cushioned with tough wood, so as to avoid the danger of dumping when lifting.
4. After the jack has lifted the heavy object, the heavy object shall be firmly supported by the tough wood in time, and the jack shall not be used as a support to avoid unbalanced load and danger of dumping.
5. When using, firstly connect the quick joint of the hand pump to the top, then select the position, and screw the oil drain screw on the oil pump to work. Loosen the drain screw and unload the cylinder.
6, electric pump, please refer to the electric manual.

Electric hydraulic jack precautions
1. When emptying the oil drain screw on the pump body, you can relax. Empty the pump vertically and raise it with your head down. Then tighten the drain screw and you can continue to use it.
2. Remove the quick connector at the load and avoid to avoid accidents and mechanical damage.
3. The media for oil and maintenance equipment must be prepared for the electrohydraulic jacks to avoid the consequences of clogging or spillage.
4, new or long home storage hydraulic jack, due to the beginning of more air in the fuel tank, the piston rod may appear a slight and sudden jump, oil jack airborne reciprocating 2-3 times to eliminate air in the cavity room. The long idle socket makes the hardened seal, because the seal does not work for a long time, thus affecting the service life of the hydraulic jack, so when the electric hydraulic jack is not in use, the monthly hydraulic jack unloads and reciprocates 2-3 times.
The above is the entire contents of the use of electro-hydraulic jacks, troubleshooting methods and precautions that Xiaobian introduced to everyone. Electro-hydraulic jacks are widely used in construction, shipbuilding, metallurgy, mining, petrochemical, railway engineering, and other industries. Jacking, stretching, squeezing and other operations.
