Description

Technical Field

[0001] The present application relates to the technical field of hydraulic pumps, and in particular to a hydraulic pump shock-absorbing base. Background Art

[0002] A hydraulic pump is a type of hydraulic pump. There are single-circuit and double-circuit hydraulic pumps. The function of a hydraulic pump is to convert the mechanical energy of a power machine (such as an electric motor and an internal combustion engine) into the pressure energy of a liquid. The operation process is: the cam is driven to rotate by the electric motor. When the cam pushes the plunger upward, the sealed volume formed by the plunger and the cylinder body decreases, and the oil is squeezed out of the sealed volume and discharged to where it is needed through a one-way valve. When the cam rotates to the descending part of the curve, the spring forces the plunger downward to form a certain vacuum. The oil in the oil tank enters the sealed volume under the action of atmospheric pressure. The cam causes the plunger to rise and fall continuously, and the sealed volume decreases and increases periodically, so the pump continuously absorbs and discharges oil.

[0003] Hydraulic pumps are widely used in industries such as electricity and construction. Hydraulic pumps will generate large vibrations when working. The current hydraulic pump base has a poor shock absorption effect. When the hydraulic pump is running, it is easy to cause large vibrations. Severe vibrations will cause damage to the hydraulic pump. Therefore, in order to solve the above problems, we provide a hydraulic pump shock absorption base. Utility Model Content
