Abstract
The invention discloses a switch control system for a high-pressure cleaning machine. The switch control system comprises a high-pressure pump, a drive motor and a power source for providing power to the drive motor. A water inlet of the high-pressure pump is connected with a water source. A water outlet is connected with a high-pressure water gun. The switch control system further comprises a motor controller and a signal switch box. The power source is connected with the drive motor thorough the motor controller. The motor controller controls the drive motor to operate at a constant rotating speed. The drive motor drives the high-pressure pump to operate, and the water pressure of the water outlet of the high-pressure pump is kept constant. According to the switch control system, even under the condition that electric energy transmitted to the drive motor decreases gradually, the pressure generated by the high-pressure pump is high enough to jack and open a safety valve, it is guaranteed that the safety valve cannot fail, high-pressure water in the pump overflows into the water inlet end of the pump, the pressure in the pump cannot rise, and the protection function is played.

Technical field
The present invention relates to a kind of cleaning means, particularly relate to a kind of jetting machine.
Background technology
Jetting machine, is to make high-pressure plunger pump produce water under high pressure by power set to rinse the machine of body surface.
Dirt can be peeled off by it, washes away, and reaches the purpose on cleaning of objects surface.Because be to use water jets under high pressure cleaning dirt, so high
It is also one of the cleaning mode of universally acknowledged most scientific, economy, environmental protection that pressure is cleaned.
By driving engine to divide, motor drives jetting machine, gasoline engine to drive jetting machine and diesel driven to clean
Machine three major types.As its name suggests, these three cleaning machine is equipped with high-pressure pump, and except for the difference that they are respectively adopted and motor, gasoline engine
Or diesel engine is connected, thus drive high-pressure pump running.
General domestic jetting machine uses motor to drive, mainly by control system, circuit, gas circuit, water route and machine mostly
Tool structure is constituted.Work process is: battery is powered to motor, and motor drives high-pressure pump work, and current are entered by the import of high-pressure pump
Enter in pump, high-pressure pump supercharging become water under high pressure, and discharged by high pressure delivery side of pump, enter giant, giant spray
Go out, reach to remove the effect of pollution.The technological difficulties that current motor-driven jetting machine exists are: when whole system exists
During continuous firing, the energy content of battery is being also gradually to reduce, and controller flows to the electric energy of motor and also reducing, and causes turning of motor
Speed is slack-off, and the hydraulic pressure that pump produces in decline, after High Pressure Gun is closed, does not has the water under high pressure of enough energy to drive yet inside pump
The relief valve 7 of pump works, so arranged at safety valve is in the state lost efficacy, because not having signal to send cut-out motor power to controller
Instruction, motor operates in high capacity always, and electric current is very big, and whole system is burnt soon.
Summary of the invention
Goal of the invention: present invention aim at for the deficiencies in the prior art, it is provided that a kind of protection jetting machine safety
The on-off control system of work.

The power supply of described driving motor supplies power, the water inlet of described high-pressure pump is connected with water source, and outlet is connected with giant,
Also including electric machine controller and signaling switch box, described power supply is connected with described driving motor by described electric machine controller, institute
Stating driving motor at constant rotating speed running described in motor controller controls, described driving motor drives the work of described high-pressure pump, and keeps
The outlet water pressure invariableness of described high-pressure pump；
Described signaling switch box is connected with the relief valve of described high-pressure pump, and described relief valve opens, when closing, described relief valve band
Dynamic described signaling switch box is closed, is connected, and described signaling switch box is connected with described electric machine controller, to described electric machine controller
Send closedown, enabling signal, described in described motor controller controls, drive motor to stop, starting working.
The present invention further preferably technical scheme is, described signaling switch box is arranged on the side of described high-pressure pump, institute
The overhead height stating signaling switch box is consistent with the overhead height of described relief valve, described signaling switch box and described relief valve it
Between connected by connecting rod, one end of described connecting rod is fixed on the top of described relief valve, the other end and described signaling switch
Box contacts, and connects described signaling switch box；When described relief valve is opened, described connecting rod is followed described relief valve and is moved upward,
Disconnecting described signaling switch box to connect, during described relief valve Guan Bi, drive described connecting rod to reset, described connecting rod is connected described
Signaling switch box.
Preferably, described power supply is vehicle power, battery one of which.
Preferably, described driving motor is outer rotor brushless motor.
Preferably, described high-pressure pump is high-pressure plunger pump.
Beneficial effect: the on-off control system mesohigh pump of (1) present invention is by driving motor drive operational, and drives motor
Working further through motor controller controls, motor controller controls drives the constant speed operating of motor, owing to the rotating speed of motor is constant,
Ensure that the hydraulic pressure that high-pressure pump produces will not change, though situation about being gradually reduced at the electric energy flowing to driving motor
Under, the pressure that high-pressure pump produces also be enough to back down relief valve, it is ensured that relief valve will not lose efficacy, and the water under high pressure in pump is overflowed to pump
Water inlet end, make the pressure in pump no longer raise, play the effect of protection；It addition, the relief valve of the present invention and signaling switch box
Connecting, relief valve becomes linkage status with signaling switch box-like, and when relief valve is opened, signaling switch box sends to electric machine controller
Shutdown signal, motor controller controls drives motor to quit work, it is to avoid motor is continuously in high capacity operating condition, burns whole
Individual system；
(2) power supply of the present invention is vehicle power, battery one of which, can meet whole demands of domestic, accessible civil power, vapour
Car power taking, it is also possible to by battery, outwork, easy to use, there is good versatility；
(3) motor in the present invention is brushless electric machine, compares common electric machine due to the efficiency of brushless electric machine and wants high by 20%, Ke Yi great
The big use time extending cleaning machine.
