Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing and sound-absorbing equipment, in particular to a shock-absorbing and sound-absorbing device for an oil pump. Background Art

[0002] The oil pump will vibrate during the actual operation, and it will also be accompanied by noise. This will affect the working environment, and even affect the working status of the staff and the quality of life of the surrounding people. At the same time, if the oil pump vibrates for a long time during the actual operation, it will also have a certain impact on the working performance of the oil pump itself, thereby reducing the service life and quality of the oil pump.

[0003] In the prior art, in order to reduce the vibration and noise of the oil pump, most of them install rubber foot pads under the oil pump, or place the oil pump on a platform, and install steel wire shock absorbers under the platform to reduce the shock of the entire oil pump. Both of the above shock absorption methods can play a role in shock absorption and noise reduction to a certain extent, but the effect is not significant, and can even only ensure the normal operation of the oil pump. Although installing a steel wire spring can reduce the vibration effect of the oil pump vibration on the connected objects, the steel wire spring directly connects the oil pump that generates vibration with the fixed object. The vibration will still have a vibration effect on the fixed object, and the noise generated by the oil pump itself cannot be blocked.

[0004] Therefore, in response to the current problems, how to provide a shock-absorbing and silencing device for an oil pump that can ensure that the impact of the vibration and noise of the oil pump on the contact object is effectively reduced is an issue that technical personnel in this field urgently need to solve.

[0014] Preferably, in the above-mentioned vibration-absorbing and noise-reducing device for an oil pump, the number of the cooling fans is multiple, and each cooling fan is fixed on the side wall abutting against the side wall where the through hole is located or on the same side wall. The cooling fan cooperates with the vent to suck cold air into the box body and discharge hot air, so that the heat dissipation of the oil pump can be achieved.

[0015] Preferably, in the above-mentioned vibration-absorbing and noise-reducing device for an oil pump, the box body includes a box body and a cover body, the bottom end of the cover body is hinged to the top end of the box body; the fixing bracket is located in the box body; the bottom wall of the box body is provided with a vent, and the through holes and the cooling fan are arranged on two groups of corresponding side walls. Thus, the oil pump can be placed in the box body, and the oil pump can be replaced and adjusted.

[0016] Preferably, in the above-mentioned vibration-absorbing and noise-reducing device for an oil pump, a plurality of vibration-absorbing air bags are fixed to the outer bottom wall of the box body to eliminate the remaining vibration.

[0017] Preferably, in the above-mentioned vibration-absorbing and noise-reducing device for an oil pump, the elastic vibration-absorbing member is a tension spring. The oil pump is suspended on a fixed bracket to block the vibration of the oil pump to the base surface of the fixed object.
