Gaodetec Equipment is 100 150 200 250 300 500 1000 ton double acting hydraulic cylinder with electric pump for sale manufacturers and supplier made in China.

Double acting hollow prestressed post tensioning jack is a double acting hydraulic cylinde with convenient operation and control, which is especially suitable for large-scale projects. In order to protect the safe operation of the jack, the jack has a built-in pressure relief valve to prevent overload, and a safety device is designed. The cylinder joint adopts high-pressure rubber hose and threaded joint, which has the advantages of fast operation and overcomes the disadvantage of oil leakage of traditional joint. China's Prestressed double acting hydraulic cylinder with electric pump is mainly used for concrete post tensioning prestress and tensioning steel strand.

The high pressure 50 100 150 200 250 300 500 1000 ton double acting hydraulic cylinder with electric pump is powered by ZB series high-pressure electric oil pump, which has the functions of oil pressure rebound and overflow. The safety protection booster is designed to protect the emergency overpressure, and the special structure can protect the oil cylinder. The double acting hydraulic cylinder with electric pump can withstand the eccentric load of 5% of the rated pressure. High pressure hydraulic cylinder is very durable, especially in large projects, it is easy to operate and control. It can be used for hoisting heavy machinery, bridge engineering, water conservancy engineering, port construction and other equipment. It has the advantages of large output, light weight and remote control. It can be matched with our high-pressure oil pump, and can achieve a variety of operation modes such as Jack, push, pull and extrusion.

The 50 100 150 200 250 300 500 1000 ton double acting hydraulic jack with electric pump can be used for the maintenance of large machinery, the overall hoisting of bridges, the maintenance of hydropower station gates, the hoisting of steel structures and the installation of supporting equipment.

Double acting hollow hydraulic cylinder combines all the design features of single acting and the advantages of double acting design, so as to improve the operation and use speed, especially in the operation of relatively long stroke. The piston center of double acting hollow cylinder has a through hole, which is widely used in nuclear power plants, tunnel engineering, underground engineering, buildings and other occasions to realize the preloading process, and can also be used for other similar needs

The double acting hydraulic cylinder sold can be equipped with two-way manual oil pump or two-way electric oil pump. Due to the through hole in the middle, the hollow jack not only has the lifting capacity of the general hydraulic jack, but also has the stretching and tensioning functions that the general Jack does not have. Through holes allow cables, wire ropes and other shafts to pass through. The hollow roof has dual functions and hydraulic retraction function. Double acting hollow cylinder is the first choice for various large projects. It has the characteristics of convenient operation and control. The new technology and structure make the hollow ceiling Jack safer and longer service life.

The 50 100 150 200 250 300 500 1000 ton double acting hydraulic cylinder with electric pump has the following characteristics:

1. Exquisite design, small size, light weight and easy to carry.

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

3. If the sliding part and steel alloy of the piston are made of wear-resistant materials, the surface of the piston rod is plated with hard chromium, with good wear resistance and rigidity.

When using hydraulic cylinder with electric pump, the following points should be kept in mind:

a). In case of out of control during use, loosen the drainage screw on the pump body first, then lift the pump body vertically and run down, and then tighten the drainage screw to wait for a sense of stress. Continue to use.

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

c). The machine takes oil as the medium, and the oil and machine must be well maintained to avoid blockage or oil leakage and affect the use effect.

d). For new or long-term placed hydraulic jacks, due to more air in the oil cylinder, the piston rod may suddenly jump slightly at the beginning of use. The hydraulic jack can stand upside down and reciprocate 2-3 times without load. Remove air from the cavity.
