The utility model compared with prior art has many advantages and good effect:
In the carwash process, need to suspend clean and needn't close main power switch artificially when turn-offing current, avoided frequent unlatching cleaning machine high-pressure hydraulic pump, accomplished that really the time spent promptly opens, use up a period of time promptly to close automatically.Easy for operation, time saving and energy saving, both improved operating efficiency, energy efficient reduces unnecessary wearing and tearing again, improves the service life of machine.And control circuit is simple, practical, and cost is lower.
Description of drawings
Fig. 1 is the control circuit figure of a kind of automatic close-type high pressure washer of cutting off the water supply of the utility model.
The specific embodiment
A kind of automatic close-type high pressure washer embodiment that cuts off the water supply, mainly by giant, by water tank and the high-pressure hydraulic pump that pipeline links to each other with giant, the high-pressure hydraulic pump electromotor control circuit is formed.Referring to Fig. 1, a water flow switch K is arranged in the high-pressure hydraulic pump electromotor control circuit
1Open K with a hydraulic pressure
2Be arranged in the pipeline that giant is connected to water tank water flow switch K
1With a hydraulic pressure switch K
2The contact parallel connection after be serially connected in the current supply circuit of a power-off delay relay JS.The normally opened contact JS-1 of power-off delay relay JS is serially connected in the current supply circuit of an auxiliary reclay J1, and the normally opened contact J1-1 of auxiliary reclay J1 is serially connected in the current supply circuit of high-pressure hydraulic pump motor M.Hydraulic pressure switch K wherein
2Be normally closed type, its contacting when promptly the hydraulic pressure in the pipeline is normal pressure, the contact disconnected when pressure was higher than normal pressure.Water flow switch K
1Be often-cutting type, the contact disconnects when its contacting when promptly in the pipeline current being arranged, no current.
The course of work of automatic close-type high pressure washer of cutting off the water supply is as follows:
Connect power switch K, open giant, the interior hydraulic pressure of water pipe this moment is normal pressure, hydraulic pressure switch K
2The closing of contact, power-off delay relay JS work, its contact JS-1 closure, auxiliary reclay J1 action, its contact J1-1 closure, the high-pressure hydraulic pump motor M work of switching on.There is water to flow water flow switch K in the water pipe
1The closing of contact; When hydraulic pressure is upgraded to high pressure in the water pipe, hydraulic pressure switch K
2The contact disconnect because water flow switch K
1Contact and hydraulic pressure switch K
2The contact be in parallel, the high-pressure hydraulic pump motor M work of still switching on, giant ejection water under high pressure enters conventional cleaning state.
When closing hydraulic giant when the cleaning of needs time-out, water is no longer mobile in the water pipe, water flow switch K
1The contact disconnect, have hydraulic pressure in the water pipe this moment, hydraulic pressure switch is in off-state, time-delay relay JS outage, pick up counting, at this moment, contact JS-1 is still closed, after delay time reaches setting value, contact JS-1 disconnects, auxiliary reclay J1 dead electricity, and its contact J1-1 disconnects, high-pressure hydraulic pump motor M dead electricity quits work.
When opening giant once more, the pressure in the water pipe returns to conventional pressure, hydraulic pressure switch K
2Connect, power-off delay relay JS work, its contact JS-1 closure, auxiliary reclay J1 action, its contact J1-1 closure, the high-pressure hydraulic pump motor M work of switch on has water mobile, water flow switch K in the water pipe
1Closure enters conventional cleaning state.
The effect of power-off delay relay JS mainly is to prevent frequent shut-off nozzle in the short time and the high-pressure hydraulic pump motor M frequent starting that causes, as hydraulic pressure switch K
2With water flow switch K
1Time-delay relay J S work when any one is connected, relay J 1 action, high-pressure hydraulic pump motor M work is as hydraulic pressure switch K
2With water flow switch K
1When all disconnecting, time-delay relay JS quits work high-pressure hydraulic pump motor M after time-delay a period of time.Time-delay relay JS delay time length can freely be set according to actual needs.
Auxiliary reclay J1 is the relay (as JTX-2Z) that a normally opened contact was powered, had to common alternating current 220V among Fig. 1, and JS is the adjustable power-off delay relay that a normally opened contact was powered, had to common alternating current 220V.
Be convenient to move and work alone for making the automatic close-type high pressure washer of cutting off the water supply, water tank that will link to each other with giant by pipeline and high-pressure hydraulic pump all are arranged on one movably in the cabinet, and a dust suction water scooping machine and a generator or a batteries to the high-pressure hydraulic pump power supply also are set in the cabinet.The cabinet bottom surface is provided with wheel, and cabinet one sidewall connects a go-cart handrail.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example.Those skilled in the art, in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
