活塞端面与缸筒端面紧贴在一起。启动时，活塞承力面积不够，故不能推动负载

The end face of the piston and the end face of the cylinder are closely attached to each other. <br>When starting, the bearing area of ​​the piston is not enough, so the load cannot be pushed. As a result, the speed of the cylinder of the plate bending machine is slowed down when it moves. <br>It is worth mentioning that this situation is often caused by the lack of meticulous preparatory work before starting. <br>We should not neglect the overhaul of machinery and equipment under any circumstances to avoid accidents.

The piston end face is close to the cylinder barrel end face.<br>At start-up, the piston load area is not enough, so it cannot push the load. As a result, the coil oil cylinder slows down when moving.<br>It is worth mentioning that this situation often occurs due to the lack of detailed pre-start preparation.<br>Under no circumstances should we neglect to repair machinery and equipment to avoid accidents.
