Description
Technical field
The utility model relates to a kind of cleaning equipment protective device, is a kind of jetting machine intelligence overpressure protection apparatus specifically.
Background technology
Current jetting machine is divided into cold-water high-pressure cleaning machine and hot-water jetting machine.All that hot-water jetting machine uses boiler to heat by power set make high-pressure pump produce water under high pressure carries out cleaning etc. aspect process a kind of equipment to body surface.Jetting machine is extensive in sector applications such as industry cleaning link, environmental sanitation cleaning, construction, stone material process, timber processing.
At present, because of mechanical disorder or artificial being heightened by pressure, rated pressure is exceeded to jetting machine and damages the protection of high-pressure wash or generation security incident, general use safety valve is as protector, and safety valve setting pressure just can normally must use higher than jetting machine rated pressure 10%, and it is easy to wear to there is mechanical part in safety valve, fault rate is high, service life is short, the setting of safe pressure value is inaccurate, job insecurity, partial pressure can only be laid down, jetting machine can not be closed with problems such as cutoff high generations, can not effectively protect jetting machine superpressure phenomenon.
Utility model content
The utility model provides a kind of jetting machine intelligence overpressure protection apparatus, exceedes rated pressure work and the security incident that produces, effectively to protect high-pressure wash safety and operating personnel's personal safety in order to solve jetting machine.
Described a kind of jetting machine intelligence overpressure protection apparatus, comprise high-pressure pump, drive high pressure pump drive motor and the control circuit of dynamic high-pressure pump, it is characterized in that: in described high-pressure pump high-pressure outlet water route, a pressure sensor is housed, high-pressure pump water outlet is provided with a pressure regulator valve, in pressure sensor lead-out wire connecting system control circuit, be made up of Programmable Logic Controller and Electric Machine Control ac contactor coil in control circuit, pressure sensor lead-out wire is connected with the signal input port of Programmable Logic Controller, in order to detect the discharge pressure parameter of jetting machine in real time, the signal output part of Programmable Logic Controller is connected with high pressure pump drive motor through contactor coil, and when monitoring superpressure, the power supply of cutoff high cleaning machine control ac contactor coil makes the power-off of high pressure pump drive motor.
The utility model provides a kind of jetting machine intelligence overpressure protection apparatus; this integration of equipments parts such as pressure sensor, Programmable Logic Controller; jetting machine can be solved and exceed rated pressure work and the security incident produced, effectively can protect high-pressure wash safety and operating personnel's personal safety.
The utility model has the following advantages:
1, the setting of safe pressure value accurately;
2, owing to there is no mechanical wear, working stability, failure rate is low, long service life;
3, protective reaction speed is fast;
4, superpressure stoppage protection can be realized;
5, cost price is cheap.
Accompanying drawing explanation
Fig. 1 is a kind of jetting machine intelligence of the utility model overpressure protection apparatus schematic diagram;
Fig. 2 is a kind of jetting machine intelligence of the utility model overpressure protection apparatus circuit diagram.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described below by specific embodiment.
A kind of jetting machine intelligence overpressure protection apparatus described in the utility model, comprise high-pressure pump 2, drive high pressure pump drive motor 1 and the control circuit of dynamic high-pressure pump 2, it is characterized in that: in described high-pressure pump 2 high-pressure outlet water route, a pressure sensor 5 is housed, high-pressure pump water outlet is provided with a pressure regulator valve 3, in pressure sensor lead-out wire 4 connecting system control circuit, be made up of Programmable Logic Controller 7 and Electric Machine Control ac contactor coil 8 in control circuit, pressure sensor lead-out wire 4 is connected with the signal input port of Programmable Logic Controller 7, in order to detect the discharge pressure parameter of jetting machine in real time, the signal output part of Programmable Logic Controller 7 is connected with high pressure pump drive motor 1 through contactor coil 8, and when monitoring superpressure, the power supply of cutoff high cleaning machine control ac contactor coil 8 makes high pressure pump drive motor 1 power-off.
During use, adopt pressure sensor 5, respond to the pressure of jetting machine high pressure water circuit system at any time, to provide real-time pressure sensing, real-time guard.
Adopt Programmable Logic Controller 7 as master controller; the signal imitation of pressure sensor 5 is converted to data signal; by software programming control to the analysis of data signal and setting value contrast; if real-time pressure exceedes setting value; Programmable Logic Controller 7 sends instruction, and jetting machine is shut down, thus cutoff high source; play the effect of protection, also can prevent from artificially adjusting jetting machine pressure and the security incident occurred.
The foregoing is only the detailed description of specific embodiments of the present utility model; the utility model is not limited with this; all do in mentality of designing of the present utility model any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
