The difference with the embodiment 1-5 lies in that a damping module 8 is arranged between the pump module 2 and the oil delivery pipe 3 and the pump 202, two ends of the damping module 8 are provided with telescopic springs 801, the inner side of the telescopic springs 801 is provided with a corrugated pipe 802, an interlayer is arranged inside the corrugated pipe 802, a stainless steel wire mesh is arranged at the interlayer, and the damping module 8 is arranged at two ends of the telescopic springs 801 and is provided with fixing clamping plates 803.
As shown in fig. 7, due to the property principle of the thin oil material, the formed fluidity is poor, and therefore, the pressure at the position of the pump 202 and in the oil delivery pipe 3 is high, and the surface vibration of the pump module 2 can be caused under the flow along with opening and closing, so that the vibration damping module 8 can well reduce the transverse vibration efficiency of the pump module 2, the set expansion spring 801 is fixed left and right based on the fixing splint 803 structures at the two ends, the rigidity and elasticity of the pipe body are increased according to the corrugated pipe 802 with the stainless steel wire mesh in the middle, and the integral vibration damping structure forms three-point vertical vibration damping, so that when the start-stop state occurs, the generated vibration is mainly absorbed by the vibration damping module 8, so as to reduce the left-right shake of the pump module 2, and avoid the loss of the internal gear set of the speed reducer caused by the shake of the start-stop of the pump module 2.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
