Double acting hollow cylinder for sale combines all the design features of single-acting and the superiority of double-acting design, thereby improving the operation and use speed, especially in the relatively long stroke operation. The double acting hollow cylinder has a through hole in the piston center, which is widely used in nuclear power plants, tunnel engineering, underground engineering, construction and other occasions to realize the pre-tightening process, and can also be used in other similar needs.

The double acting hollow cylinder for sale can be equipped with a two-way manual oil pump or a two-way electric oil pump. Because of the through hole in the middle, the hollow jack not only has the lifting capacity of a general hydraulic jack, but also has the stretching and tensioning functions that the ordinary jack does not have. The through hole allows cables, steel ropes and other shafts to pass through. The hollow roof has double functions and hydraulic retraction. The double acting hollow cylinder is the first choice for various large-scale projects. It has the characteristics of convenient operation and control. The new technology and structure make the hollow roof Jacks are safer and last longer.

Double acting hollow cylinder for sale has the following features:

1. The design is exquisite, compact, light in weight and easy to carry.

2. It is used to stretch cables, steel locks, bolts and bars through hollow penetration holes. It is widely used in the disassembly and assembly of main shaft and tail shaft of various shipyards.

3. If the sliding part of the piston and steel alloy are made of wear-resistant materials, the surface of the piston rod is plated with hard chrome, which is wear-resistant and rigid.

When using the double acting hollow cylinder, we should remember the following things:

a). If there is a runaway phenomenon during use, you can first loosen the drain screw on the pump body, then lift the pump body vertically and run it downwards, then tighten the drain screw, and wait for a sense of force. continue to use.

b). When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.

c). This machine uses oil as the medium, so the oil and the machine must be well maintained to avoid clogging or oil leakage, which will affect the effect of use.

d). For new or long-placed hydraulic jacks, because there is more air in the cylinder, the piston rod may suddenly jump slightly when you start to use it. The hydraulic jack can be inverted and reciprocated 2-3 times without load. Eliminate the air in the cavity.
