When the cylindrical type two directional hydraulic jack is working, the hydraulic pressure retracts, and the overflow function limits the stroke. There is a special safety pressure holding device to prevent sudden over pressure. The special structure plays a multiple protective role for the jack. Cylindrical type two directional hydraulic jack has the characteristics of large output power, light weight, and long-distance operation in any space position. Equipped with an electric hydraulic pump station, two directional hydraulic jack for sale can realize various types of jacking, pushing, pulling, squeezing, and pressing. The two directional hydraulic jack is widely used in equipment installation and maintenance of transportation, railways, bridges, shipbuilding, construction, factories and mining enterprises.

Different types of hydraulic jacks have different working principles. Cylindrical type two directional hydraulic jack plays an important role in the industrial field. Using the principle of hydraulic oil transmission, in each passage, the conventional problems encountered by hydraulic jacks, compared with its many advantages, or slightly less. When the oil pump continuously presses oil into the oil cylinder, the oil pressure in the oil cylinder increases continuously, so it will force the piston and the weight on the piston to move upward together. When the piston reaches its stroke, it will not continue to move upward. By working the pumping station in the opposite direction, the oil circuit is promoted to flow in the opposite direction, and the piston of the oil cylinder is driven to retract.

Precautions when using the cylindrical type two directional hydraulic jack:

1. If there is a runaway phenomenon during use, you can first loosen the oil drain screw on the pump body, lift the pump body vertically and run it downwards, and then tighten the drain screw to continue using.

2. When using, do not add partial load or overload to avoid the danger of jack damage. When there is a load, do not remove the quick coupling to avoid accidents and damage to the parts.

3. This cylindrical type two directional hydraulic jack uses oil as the medium, so the oil and the machine must be well maintained to avoid blockage or oil leakage, which will affect the use effect

4. Strictly abide by the technical specifications during operation, and the user should check and maintain it regularly according to the conditions of use.

We should pay attention to the following matters when buying two directional hydraulic jack for sale:

1. Tonnage: The first thing to choose a hydraulic jack is the tonnage of the hydraulic jack. It is recommended that the hydraulic jack has a higher tonnage than the load.

2. Determine the height and stroke of the body: According to the actual requirements, select the appropriate body height and the required stroke. The height of the body of the hydraulic jack is greater than the stroke. This is the most basic common sense.

3. Frequency of use: According to the requirements of the working conditions, the maintenance level and the industrial level are distinguished. If the hydraulic jack is used for production or particularly high frequency use, please specify.
