Double-acting hydraulic jack with oil pump is a lifting device that integrates oil pump and hydraulic cylinder. It uses oil pump to convert mechanical energy into hydraulic energy, realizes reciprocating motion through hydraulic cylinder, thus generating thrust in two directions to complete lifting or lowering action.

Double-acting hydraulic cylinders have significant advantages in lifting applications, providing large output force, precise control, strong adaptability and high efficiency and energy saving.
Advantages in lifting applications
Large output force: Double-acting hydraulic cylinders can provide large output force and are suitable for lifting heavy equipment or objects. For example, some double-acting hydraulic cylinders have a capacity of up to 200 tons, which can easily cope with the lifting needs of high-tonnage equipment.
Precise control: By adjusting the pressure and flow of the hydraulic system, the movement speed and position of the double-acting hydraulic cylinder can be precisely controlled to achieve smooth and accurate lifting operations.
Strong adaptability: Double-acting hydraulic cylinders have a compact structure, occupy a small space, and can be customized according to different working environments and requirements. This allows them to adapt to various complex lifting scenarios.
High efficiency and energy saving: Compared with traditional mechanical lifting methods, double-acting hydraulic cylinders have higher energy conversion efficiency. At the same time, by recycling and utilizing hydraulic energy, energy saving and consumption reduction can also be achieved.

The 700bar Hydraulic Jack Pump is a high pressure hydraulic pump specifically designed to drive hydraulic jacks, providing working pressures up to 700 bar (approximately 10,000 psi).

A single acting hydraulic cylinder has only one working chamber, meaning oil can only enter from one port and exit from the other. Therefore, it can only achieve unidirectional movement with the help of a one-way hydraulic control valve. The pump for a single acting hydraulic cylinder is responsible for supplying pressurized oil to this chamber, driving the piston to move in one direction. In the return stroke, the piston is usually pushed back by external forces such as a spring, gravity, or load.

Electric Oil Pumps for Hydraulic Jacks are widely used in various construction scenarios, particularly in pre-tension or post-tension applications for concrete constructions, such as:
Bridge construction
Railway and highway construction
Underground structures
Buildings
Channel construction

The working principle of the prestressed concrete oil pump is mainly based on the principle of hydraulic transmission. The oil pump is driven by an electric motor or an internal combustion engine to suck the hydraulic oil from the oil tank, and then pressurizes it through a high-pressure pump and delivers it to the hydraulic jack. Under the action of the hydraulic jack, the prestressed steel bars or steel strands are gradually tensioned to the tensioning force required by the design and anchored by anchors. During the whole process, the oil pump needs to maintain a stable pressure and flow to ensure the smooth progress of the tensioning process.

The working principle of the high-voltage double acting hydraulic jack for building is based on Pascal’s law, that is, the pressure on a confined liquid can be transmitted in all directions without changing its magnitude. When an external force is applied, the force will be evenly transmitted to all parts of the container by the liquid. The mechanical energy is converted into the pressure energy of the liquid through the hydraulic pump, and then the pressure energy of the liquid is converted into mechanical energy through the hydraulic cylinder, thereby realizing the transmission and amplification of force.

It has large output, light weight, remote control and other advantages, it can match with our high pressure oil pump, it can reach jack, push, pull and extrusion and kinds of working.
