In the process of using the center hollow hydraulic jack, if empty pumping occurs, you can first loosen the oil drain screw on the pump body, turn the pump body vertically and pump it downward for a few times, then tighten the oil drain screw. Continue to use, there is a lot of common sense that needs to be understood, and only after an in-depth understanding can its effect be exerted better, so what kind of knowledge do you have? Let me give you a brief introduction to the relevant knowledge points.
Under normal circumstances, it can be learned that in the specific operation and application of the center hollow hydraulic jack, the relevant personnel start the motor switch or tilt the handle of the manual pump up and down, and then tighten the shut-off valve of the manual pump or electric pump clockwise.
At this time, the oil pump oil is supplied to the center hollow hydraulic jack, and the center hollow hydraulic jack piston rises slowly under pressure, while the wire rope or mandrel in the center hole rises at the same time, thereby pulling the weight or mandrel under the wire rope to be stretched.
When the weight rises to the specified position, if the next round of work is required, the stop valve can be unscrewed counterclockwise, and the piston will return quickly under the action of the spring force. According to the above operation method, so repeatedly, in order to complete the entire cycle action.
The above are the relevant knowledge points that you need to know when using the center hollow hydraulic jack. If you want to get more information, quotations or videos about the center hollow hydraulic jack, please contact us directly: sales1@leadcrete.com.
