Description
Technical field
The invention belongs to cleaning equipment technical field, relate to a kind of high pressure water cleaning device, relate in particular to a kind of giant pumping plant with gunlock interlock.
Background technology
In actual life, the giant that carwash or cleaning equipment are used is configured to: high-pressure hydraulic pump, water pipe, hydraulic giant.Be that water pump is directly connected with hydraulic giant, open after water pump the effect of hydraulic giant competence exertion.People in actual use, need to first open water pump, and then go to the position that need to clean and carry out operation, after cleaning, need again to walk to return to switch off the pump, very inconvenient.In addition, also have the problem of security, in the time of people's operation, because contingency causes hydraulic giant, slip out of the hand, hydraulic giant cuts out, and water pump can not be closed down in time, likely causes danger.Therefore, poor by the mode operability of pump control hydraulic giant.
People are through constantly exploring, various solutions have been proposed, as Chinese patent literature discloses a kind of supply-water pump control device [notification number: CN203061526U] of lathe hydraulic giant, comprise water pump, ball valve, check valve, minute water piece, pressure switch, water pipe and hydraulic giant; Described water pump is connected with the left end of described ball valve; The right-hand member of described ball valve is connected with the left end of described check valve; The right-hand member of described check valve is connected with described minute water piece; Described pressure switch is connected with described minute water piece; Described water pipe is connected with described minute water piece; Described hydraulic giant is arranged on described water pipe.
Such scheme water pump can open, stop automatically according to the open and close state of hydraulic giant reality, without Artificial Control, and handled easily; In addition, water pump, without long-play, has not only extended the service life of water pump, and has saved in a large number electric power resource, reduces cost of use.But such scheme is only provided with a pressure switch, in actual use, security performance is not good enough and need to change different nozzles and could realize different working pressures, and the applicability of equipment is poor.
Conventionally, single pressure switch has two kinds of mounting means, a kind of being contained in before unloader, and a kind of is to be contained in after pressure regulator valve (unloader and pressure regulator valve difference: unloader can only off-load, during off-load, keep setting pressure, pressure regulator valve can electrodeless adjusting pressure and pressure trend 0 during full off-load).
Be contained in before unloader: as set relief valve off-load value, be 10MPa, pressure switch preset value is 9MPa (preset value of pressure switch does not allow operation change after dispatching from the factory).While requiring pressure to be 5MPa, will use 1# nozzle, closing the pressure in pipeline after spray gun will raise suddenly, and when rising to 9MPa, machine just can stop.While requiring pressure to be 2MPa, will change 2# nozzle, it is also same when rising to 9MPa closing after spray gun, and machine just can stop; Need nozzle that multiple pressure will standby a lot of models in order to changing, obviously not too convenient, that is to say that to join adaptive poor.
And in real process, close suddenly spray gun, will produce compression shock, instantaneously have 1.5 times of above preset pressure or higher, pressure can not discharge rapidly danger such as will causing booster, leakage.Because this mode has a lasting back pressure in the time of can determining pipeline off-load, its danger is higher.
Be contained in after pressure regulator valve: the force value while setting full off-load, when pressure switch detects full off-load, equipment stops.This pressure switch is generally diaphragm type structure, facts have proved that its reliability is very poor at present, be difficult to this unexpected compression shock of tolerance, so the reliability of equipment is poor.
Summary of the invention
The object of the invention is for the problems referred to above, the good reliability of a kind of good stability, equipment, the controlled giant pumping plant preferably with gunlock interlock are provided.
