Abstract
The utility model relates to an automatic unloading mechanism for a cleaning machine, comprising a pump body (13) and an unloading body (9). The utility model is characterized in that the unloading body whose lower end is provided with an unloading opening (11) is positioned in the pump body; the unloading opening is communicated with a water inlet pipe (12) of the pump body; the unloading body is provided with a plurality of high pressure water inlet holes (10) communicated with a water outlet of a high pressure pump of a cleaning machine, and water drainage holes (7) communicated with a water outlet (8) of the pump body; the upper end of the unloading body is provided with a check valve (6) which is positioned by a positioning spring (5) whose upper end contacts a screw cap (4) which is screwed on the unloading body; the upper part of the screw cap is provided with a reset spring (2) which is fixed by a pressure adjusting nut (1). The automatic unloading mechanism has the advantages of reasonable structure, convenient usage, long service life, small volume, etc.
Description
The utility model relates to a kind of cleaning machine automatic deloading mechanism.
The off-load of cleaning machine at present has two kinds of modes: a kind of is to take back pond with return pipe when cleaning machine after hydraulic giant cuts out, and the water in the pump housing is flow to the pond, and its shortcoming is need set up water pipe to lead to the pond.Another kind of unloading mechanism is to receive water inlet pipe with leather hose, forms circulation, and its shortcoming is the production cost height, and product is relatively heavier.
The utility model purpose be to provide a kind of can automatic deloading, easy to use, the life-span is long, volume is little cleaning machine automatic deloading mechanism.
The utility model technology contents in conjunction with the embodiments and accompanying drawing give to describe in detail.
Accompanying drawing is the utility model cleaning machine automatic deloading mechanism for implementing example structural representation.
This cleaning machine automatic deloading mechanism comprises the pump housing 13 and off-load body 9, off-load body 9 is arranged in the pump housing, off-load body 9 lower ends are provided with off-load mouth 11, off-load mouth 11 communicates with the water inlet pipe 12 of the pump housing 13, several high pressure inlet openings 10 and osculum 7 are arranged on the off-load body, and present embodiment is provided with four high pressure inlet openings and four osculums, and the high pressure inlet opening communicates with cleaning machine high-pressure pump delivery port, osculum communicates with the delivery port 8 of the pump housing, the delivery port water receiving rifle of pump housing during use.The upper end of off-load body is provided with a check-valves 6, and check-valves is by retainer spring 5 location, end in contact nut 4 on the retainer spring 5; Nut 4 is screwed on the off-load body, and a back-moving spring 2 is arranged above the nut, and back-moving spring 2 is fixing by pressure regulation nut 1.3 is screw among the figure, and 14 is pump body top cover, and pump body top cover 14 usefulness screws 3 are fixed on the pump housing.
This cleaning machine automatic deloading mechanism course of work is summarized as follows: when hydraulic giant closed group, delivery port 8 was closed, and pressure is higher than back-moving spring 2 pressure in the pump housing 13, off-load body 9 rises, off-load mouth 11 is opened, and water is discharged from the off-load mouth in the pump, the inlet pipeline that leads to pump housing bottom, this moment is owing to end pressure under the pump is lower than off-load body apopore pressure, closure of check ring is kept off-load body upper pressure and is higher than the back-moving spring holding capacity, and the off-load body is closed, the off-load mouth is unimpeded, automatic deloading.When hydraulic giant was opened, delivery port 8 was opened, and pump housing pressure descends, and back-moving spring 2 presses down off-load body 9, closes off-load mouth 11, cleaning machine work.
In sum, this cleaning machine automatic unloading mechanism have rational in infrastructure, easy to use, the life-span is long, volume is little etc. Advantage is the stronger cleaning machine automatic unloading mechanism of a kind of practicality.
Claims (1)
- A kind of cleaning machine automatic deloading mechanism, comprise the pump housing (13) and off-load body (9), it is characterized in that the off-load body is arranged in the pump housing, there is off-load mouth (11) its lower end, the off-load mouth communicates with the water inlet pipe (12) of the pump housing, several high pressure inlet openings (10) and osculum (7) are arranged on the off-load body, high pressure inlet opening (10) communicates with cleaning machine high-pressure pump delivery port, osculum (7) communicates with the delivery port (8) of the pump housing, the upper end of off-load body is provided with a check-valves (6), check-valves is located by retainer spring (5), end in contact nut (4) on the retainer spring, nut is screwed on the off-load body, and back-moving spring (2) is arranged above the nut, and back-moving spring is fixing by look nut (1).
