Abstract

The utility model discloses an integrated high pressure hand operate pump which consists of three independent components, i.e. the utility model is formed by transversely integrating a hand pump (20), integrated blocks (10) and a distributing valve (12) through bolt connection, wherein, the hand pump (20) comprises a plunger pump, a transmission part and an oil tank body (1); the plunger pump (7) is arranged inside the oil tank body (1); the oil tank body (1) is simultaneously used as the support part of the plunger pump (7) and the transmission part; the integrated blocks (10) are all drilling oil circuit channels, which are both the connecting plates of a safety valve (19), a pressure gauge (11) as well as oil outlets (18) and the working face of the distributing valve (12). The utility model is simple in structure, small in volume, light in weight and low in cost, is formed by integrating a plurality of hydraulic components, has no external oil pipe, and is low in pressure loss as well as applicable to the occasions without power supply. The utility model is an ideal manual high-pressure hydraulic power component which has no internal and external leakage and is suitable for double-acting oil cylinders.

Description

The integrated form high-pressure hand pump

Affiliated technical field

The utility model relates to pump, is specifically related to pump, commutation such as cuts down at the high pressure hand-operated pump structure of a kind of integrated form.

Background technique

Modal in the market hand pump is that the plunger type hand pump combines with stop valve, it is only applicable to use the occasion of single-action hydraulic cylinder, oil hydraulic cylinder return outer action of gravity, and the hydraulic system of using two-way cylinder just can only be assembled with hydraulic element independently, thereby the hydraulic system of being formed is bulky, point of attachment is many, leaks easily, and this sometimes traditional structural design can't be installed on machine simultaneously.

Summary of the invention

The purpose of this utility model is: design a kind of integrated form high-pressure hand pump, hydraulic element, the integrated realization of auxiliary are not had the compact overall structure of external oil pipe, be miniaturization, integrated design, form the general hydraulic unit that is applicable to two-way cylinder.

Technical solution of the present utility model is: this hand pump is made up of three stand-alone assemblies, promptly be connected laterally integrated with bolt by hand pump, integrated package and distributing valve, wherein, described hand pump includes plunger pump, driving component and fuel tank, plunger pump is loaded in the fuel tank, and as the supporting member of plunger pump and driving component, described integrated package all is the boring asphalt channel to fuel tank simultaneously, being the connecting plate of safety valve, pressure gauge and oil outlet, is again the working surface of distributing valve.

The utility model is simple in structure, volume is little, in light weight, integrated by a plurality of hydraulic element, it is little not have the loss of external tubing pressure, be a kind of desirable manually, high pressure, no internal and outernal leakage, be applicable to the hydraulic power parts of two-way cylinder.
