A hydraulic pump is a power component of a hydraulic system. It is driven by an engine or an electric motor. It sucks oil from a hydraulic oil tank, forms pressure oil, and sends it to an actuator. Hydraulic pump is divided into gear pump, plunger pump, vane pump and screw pump according to structure.
As a leading global supplier of drive and control technology, Rexroth has extensive project experience and product advantages in the field of mechanical applications and engineering, as well as factory automation.
Rexroth hydraulic component that provides pressurized liquid for hydraulic transmission is a type of pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into pressure energy of liquids. There are many factors that affect the service life of hydraulic pumps, in addition to the pump's own design and manufacturing factors, and the selection of some components related to the use of the pump (such as couplings, oil filters, etc.), and operations during commissioning.
Made of aluminum alloy, high strength, corrosion resistance, light weight, suitable for operation in various environments. The two-speed feature reduces the number of pressures, quickly enters the load power state in the low-pressure room, and immediately switches to high pressure, shortening each cycle. Equipped with a pressure regulating valve, which can adjust the control and set the working pressure.
The working principle of a hydraulic pump is that the movement causes a change in the volume of the pump cavity, thereby compressing the fluid so that the fluid has pressure energy. A condition that must be present is a change in the sealed volume of the pump cavity.
It is a hydraulic component that provides pressurized liquid for hydraulic transmission. It is a kind of pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into pressure energy of liquids. The figure shows the working principle of a single plunger pump. The cam is rotated by a motor. When the cam pushes the plunger to move upward, the seal volume formed by the plunger and the cylinder body is reduced, and the oil is squeezed out of the seal volume and discharged to the required place through the check valve. When the cam rotates to the lower part of the curve, the spring forces the plunger downward to form a certain degree of vacuum, and the oil in the tank enters the sealed volume under the effect of atmospheric pressure. The cam continuously raises and lowers the plunger, and the sealing volume decreases and increases periodically, and the pump continuously sucks and discharges oil.
