Hydraulic jack with hydraulic oil pump manufacturer
The working principle of hydraulic jack: The basic principle of hydraulic transmission is Pascal's principle, that is, the pressure of the liquid is the same everywhere, so that in a balanced system, the pressure exerted on the smaller piston is smaller, and The pressure exerted on the large piston is also relatively large, which can keep the liquid still. Therefore, through the transfer of liquid, different pressures on different ends can be achieved, so that a transformation can be achieved. Commonly used hydraulic jacks use this principle to achieve force transmission.
Application of hydraulic jacks: Hydraulic jacks are compact in structure, stable in work, and self-locking, so they are widely used and are mainly used in factories, mines, transportation and other departments as vehicle maintenance, lifting, and support. Its structure is light and fixed, flexible and reliable, and can be carried and operated by one person.
Classification of hydraulic jacks: General hydraulic jacks are suitable for various lifting operations with small lifting heights. It consists of: oil chamber, oil pump, oil storage cavity, piston, crank, oil valve and other main parts. When working, as long as the crank handle is reciprocated, the manual oil pump will keep pressing oil in the oil cylinder. Due to the continuous increase of oil pressure in the oil cylinder, the piston and the heavy objects on the piston will move upward together. When the oil return valve is opened, the high-pressure oil in the oil cylinder flows back to the oil storage cavity, so the heavy object and the piston also fall together. The hydraulic jack is a special tensioning machine that applies tension to the prestressed steel bars when making prestressed concrete components. The special hydraulic jacks are mostly double-acting. There are two commonly used penetrating type and cone anchor type. The penetrating jack is suitable for tensioning steel bars or wire bundles, and is mainly composed of a tensioning cylinder, a pressing cylinder, a pressing piston and a spring. Its characteristics are: there is a through hole along the axis of the stretching machine, and the steel bar (or steel wire) is inserted and anchored by the tool at the tail.
Electric hydraulic oil pump is a hydraulic component that provides pressurized liquid for hydraulic transmission, and is a kind of pump. Its function is to convert the mechanical energy of the power machine into the pressure energy of the liquid. The output flow can be adjusted according to needs is called a variable pump, and the flow cannot be adjusted is called a quantitative pump.
