Abstract

The utility model discloses a hydraulic manual pump, including piston rod, cylinder cap, cylinder, piston, the ring sum alarm wear -resistants, the piston rod is located the cylinder, still sets up the cylinder cap between the entrance of cylinder and piston rod, on the piston rod still in proper order the cover have cushion collar, piston and nut, the nut is located the afterbody of piston rod, still sets up the ring that wear -resistants on the piston, still set up the alarm on the inner wall of cylinder, the alarm is adjacent with the ring that wear -resistants. By adopting the above structure, the utility model, piston setting on this hydraulic manual pump is used for the ring and damage the alarm of reminding of wear -resistanting of protection, has improved the life of piston, avoid since piston work unusually to the damage of other mechanical devices.

Description

Hydraulic hand pump

Technical field

This utility model relates to mechanical field, is specifically related to hydraulic hand pump。

Background technology

The operation principle of hydraulic hand pump be people do work produce the pressure energy that changes mechanical energy is liquid。It is little that hydraulic hand pump has volume, is beneficial to the advantage carried, so the application of hydraulic hand pump is more and more extensive。In hydraulic system, hydraulic actuator is opened it by pressure oil or closes。Pressure oil is provided by all kinds of hydraulic pumps, current all kinds of hydraulic pump includes hydraulic hand pump and hydraulic electric pump station, need between hydraulic actuator with hydraulic pump to adopt pipeline to be connected, especially when distant, the hydraulic tube and the conduit fittings matched that connect in the middle of both will increase, thus pressure oil leakage etc. occurs, cause that hydraulic actuator action is malfunctioning。Playing an important role in this course, what prevent leakage of oil is then piston, and the piston in existing manual pump lacks protects part accordingly, it is easy to damages and can not find in time after Remedy for Piston Damage, causing the generation of final leakage of oil situation。

Utility model content

This utility model overcomes the deficiencies in the prior art; hydraulic hand pump is provided; piston on this hydraulic hand pump is arranged to the wearing ring of protection and damages the alarm reminded, and improves the service life of piston, it is to avoid due to the abnormal damage to other mechanical devices of pistons work。

For solving above-mentioned technical problem, this utility model is by the following technical solutions: hydraulic hand pump, including piston rod, cylinder cap, cylinder barrel, piston, wearing ring and alarm, described piston rod is positioned at cylinder barrel, cylinder cap is also set up between the porch and piston rod of cylinder barrel, also being cased with cushion collar, piston and nut on the piston rod successively, nut is positioned at the afterbody of piston rod, and piston also sets up wearing ring；Also setting up alarm on the inwall of described cylinder barrel, alarm is adjacent with wearing ring。Piston rod is subject to acting on to seesaw in cylinder barrel and making that cylinder barrel is inside and outside produces pressure differential by oil by then again fluid being forced into operating mechanism in cylinder body entrance press-in cylinder body of external force in use, completes one action。The wearing ring arranged on piston can reduce the friction between piston and inner wall of cylinder, improves the service life of piston。Also setting up alarm in inner wall of cylinder, when damaging occurs in piston, alarm then can send chimes of doom and remind operator, changes piston in time, it is to avoid use problematic manual pump, causes the damage to other mechanical part simultaneously。

Described piston also sets up piston primary seal。Arranging of primary seal ensures fitting tightly between piston and piston rod, it is ensured that the normal table work of piston rod。

Described piston also sets up antifouling ring。Avoid the contaminants piston in fluid, cause that piston cannot normal operation。

Dust ring and piston rod primary seal is also set up between described piston rod and cylinder cap。Above-mentioned setting ensure that what connect between piston rod and cylinder cap consolidates。

Compared with prior art, the beneficial effects of the utility model are:

1, the wearing ring arranged on piston can reduce the friction between piston and inner wall of cylinder, improves the service life of piston。

2, also setting up alarm in inner wall of cylinder, when damaging occurs in piston, alarm then can send chimes of doom and remind operator, changes piston in time, it is to avoid use problematic manual pump, causes the damage to other mechanical part。

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model。

In figure, accompanying drawing labelling is expressed as: 1, piston rod；2, cylinder cap；3, cylinder barrel；4, cushion collar；5, piston；6, nut；7, piston primary seal；8, wearing ring；9, antifouling ring；10, alarm。

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model being further elaborated, embodiment of the present utility model is not limited to this。

Embodiment 1:

As shown in Figure 1, this utility model includes piston rod 1, cylinder cap 2, cylinder barrel 3, piston 5, wearing ring 8 and alarm 10, described piston rod 1 is positioned at cylinder barrel 3, cylinder cap 2 is also set up between the porch of cylinder barrel 3 and piston rod 1, piston rod 1 is also cased with cushion collar 4, piston 5 and nut 6 successively, nut 6 is positioned at the afterbody of piston rod 1, and piston 5 also sets up wearing ring 8；Also setting up alarm 10 on the inwall of described cylinder barrel 3, alarm 10 is adjacent with wearing ring 8。

Piston rod is subject to acting on to seesaw in cylinder barrel and making that cylinder barrel is inside and outside produces pressure differential by oil by then again fluid being forced into operating mechanism in cylinder body entrance press-in cylinder body of external force in use, completes one action。The wearing ring arranged on piston can reduce the friction between piston and inner wall of cylinder, improves the service life of piston。Also setting up alarm in inner wall of cylinder, when damaging occurs in piston, alarm then can send chimes of doom and remind operator, changes piston in time, it is to avoid use problematic manual pump, causes the damage to other mechanical part simultaneously。

Embodiment 2:

The present embodiment is preferably as follows on the basis of embodiment 1: also set up piston primary seal 7 on described piston 5。Arranging of primary seal ensures fitting tightly between piston and piston rod, it is ensured that the normal table work of piston rod。

Described piston 5 also sets up antifouling ring 9。Avoid the contaminants piston in fluid, cause that piston cannot normal operation。

Dust ring and piston rod primary seal is also set up between described piston rod 1 and cylinder cap 2。Above-mentioned setting ensure that what connect between piston rod and cylinder cap consolidates。

Just this utility model can be realized as mentioned above。
