Application of the hollow jack
What common sense do you need to know before applying the process of hollow jacks?
In the process of using hollow jacks, if there is a hollow phenomenon, you can first relax the oil screw on the pump body, the pump body is vertical up head down empty play a few times, and then tighten the oil screw, you can continue to use, there are a lot of common sense need to understand it, and only after in-depth understanding can make its effect play better, what is the knowledge? The following is a small series to give you a brief introduction to its relevant knowledge points.
In general, it can be understood that in the specific operation application of the hollow jack, the relevant personnel start the motor switch or lift the manual pump handle up and down, and then tighten the manual pump or electric pump stop valve clockwise, at this time the oil pump supplies oil to the hollow jack, and the hollow jack piston slowly rises under the action of pressure. At the same time, the wire rope or mandrel of the center hole rises, thus pulling the weight or mandrel under the wire rope.
When the weight rises to the specified position, if the next round of work is needed, the stop valve can be loosened counterclockwise, and the piston is quickly returned under the action of the spring force. Follow the above operation method, and repeat to complete the entire cycle action.
