200 tons of single arm hydraulic press power blocked what are the reasons?

200 tonssingle-arm hydraulic pressReasons for power obstruction:
The possible reason is that the plunger head of the single-arm hydraulic machine is broken or the bearing in the pump falls into the pump. Although the plunger head is made of metal, the phenomenon of fracture under the huge pressure in the pump of the single-arm hydraulic machine is inevitable, and it is normal for the bearing to slip off after long-term use. In addition, the single-arm hydraulic press is used in places with serious pollution, and it is also possible that the dust and impurities in the air will eventually be stuck in the cylinder through long-term accumulation! For either reason, if the plunger pump is stuck, please close it immediately.200 tonsSingle arm hydraulic press.
