A leak-proof hydraulic oil pump

Abstract

The invention discloses an anti-leakage hydraulic oil pump. The anti-leakage hydraulic oil pump comprises an outer pump body and an inner pump body, wherein the outer walls of the left side and the right side of the outer pump body are both provided with ring grooves, clamping rods are installed in the ring grooves, transverse rods are fixed on the bottom surfaces of the clamping rods, telescopicrods are arranged on the inner sides of the clamping rods, oil ports are formed in the left and right sides on the inner pump body, and the inner pump body is positioned in the outer pump body. According to the anti-leakage hydraulic oil pump with a buffer structure, through the arrangement of the outer pump body, a traditional hydraulic oil pump in a single pump body structure is improved into adouble pump body nested structure, so that a main hydraulic power structure in the hydraulic oil pump is well protected; the clamping rods can slide in the ring grooves, in combination with elastic telescopic rod pieces formed by combining the telescopic rods and telescopic springs, the distance between the two transverse rods can be changed while moving the position of the transverse rods relative to the outer pump body, it is ensured that the outer pump body can be placed stably, and an elastic unloading force buffer structure exists in a damping tailstock.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil pumps, in particular to a leakage-proof hydraulic oil pump. Background technique [0002] Hydraulic oil pumps include vane pumps, gear pumps, plunger pumps and screw pumps. Vane pumps, gear pumps and plunger pumps are generally used in the market, and vane pumps can be divided into variable vane pumps, heat dissipation variable vane pumps, Variable vane pump with cooling pump and quantitative vane pump, etc. The hydraulic oil pump is composed of four parts: pump body, rectangular oil tank, pressure handle, and ultra-high pressure steel wire braided rubber hose. The power element of the hydraulic system is used to convert the mechanical energy of the prime mover. It is the pressure energy that can be converted into liquid, which provides power to the entire hydraulic system and is widely used in various mechanical equipment. [0003] Modern hydraulic oil pumps have weak external protection s...

Problems solved by technology

[0004] The purpose of the present invention is to provide a leak-proof hydraulic oil pump to solve the problem that the external protection structure of the modern hydraulic oil pump proposed in the above-mentioned background technology is weak, and it is easy to be subject to the vibration of the equipment or its own hydraulic work to produce combined vibration. There is a very big impact on the service life and installation. At the same time, in the hydraulic oil pump structure, judging whether the oil leaks is often assisted by the change of the hydraulic pressure. However, for trace or weak oil seepage, due to the leakage The process of oil generation is slow, and the change of hydraulic pressure may not be obvious enough. At the same time, oil seepage is sometimes invisible, and it is difficult for operators to find it in time. The problem of equipment power problem
