Various hydraulic components can be added, which are small in size, light in weight, compact in structure, easy to operate, ultra-high pressure and low flow rate, and low-pressure pumps can be used to improve production efficiency. On the basis of crude oil. Such as electromagnetic directional valves, pressure relays, remote switches, hydraulic locks, etc., can be used at any rated pressure.

Equipped with a special tool for various operations such as lifting, bending, straightening, squeezing, shearing, riveting, self lifting, stretching, dismantling, punching, construction steel squeezing, bridges, engineering machinery, etc. This product can be directly used for pressure testing of pressure vessels.

1. Wear on the inside and outside of the sealed lip.

2. Production of oil spills.

1. Two lip prints, internal and external, form two circular contact surfaces. In fact, the contact force between the two circles is uneven, and the oil will experience zero point force.

2. If the piston rod is defeated, the lips are compressed and the troops are reduced to 0, while producing oil on the other hand.

3. The surface of the groove is too rough, and the sealing material and groove between the finished oil products can generate oil due to piston movement.
