How to eliminate the blocking phenomenon of single-column hydraulic oil cylinder

The hydraulic cylinder of the single-column hydraulic press is insensitive and different from the crawling state of the hydraulic cylinder. This situation is manifested in the fact that the hydraulic cylinder cannot move immediately after the command to work the hydraulic cylinder of the single-column hydraulic press is sent out. It takes a short time before it moves, or it moves for a while and then stops moving, which mainly shows that the operation is very irregular. .
The reasons for this common fault and how to clear it are as follows:
1. There is gas in the hydraulic cylinder of the single-arm hydraulic press.
Clearing method: According to the automatic exhaust valve exhaust pipe. Check whether there is gas inhaled at the sealing ring at the position where the hydraulic cylinder moves repeatedly, and if so, replace the sealing ring.
2. The hydraulic oil pump of the single-column hydraulic press has irregular operation, and the pump rotation is hindered or slightly seized.
Removal method: According to the type of hydraulic oil pump and the reasons for its common faults, they should be solved individually. For specific methods, please refer to the relevant materials.
3. When the hydraulic cylinder of the single-column hydraulic press with buffer equipment is started in the opposite direction, the temporary stop or reverse of the piston rod often occurs.
Clearing method: The nozzle of the one-way valve of the single-column hydraulic press is very small, so that the remaining oil entering the buffer chamber is too small, and even a vacuum pump occurs, so the common fault will occur at the moment when the buffer plunger pump leaves the bearing end cover In this case, the nozzle of this product should be increased.
4. When the reciprocating speed of the single-column hydraulic press is high, the bearing steel balls flow with the oil, even blocking the valve hole, resulting in irregular movement of the hydraulic cylinder.
Cleaning method: Replace the bearing steel ball with a poppet valve or valve core with a guided shoulder.
5. The inner layer of the high-pressure hose of the hydraulic system of the single-column hydraulic press is detached, so that the fuel pipe is connected and disconnected from time to time, resulting in irregular posture of the hydraulic cylinder.
Removal method: Remove and replace the high-pressure hose.
6. The hydraulic cylinder bears a certain multidirectional load.
Removal method: Make the load borne by the hydraulic cylinder as far as possible according to the center line of the cylinder to prevent the axial force.
