A cleaning machine using an intelligent wired controller

Abstract

The invention discloses a cleaning machine with an intelligent wired controller. The cleaning machine comprises a three-phase motor (22), a plunger pump (19) and a high-pressure spray lance (1), wherein the high-pressure spray lance (1) is connected with the water outlet end of the plunger pump (19) by use of a water outlet pipe (23), while the water inlet end of the plunger pump (19) is connected with a water inlet pipe (24); the power input of the plunger pump (19) is connected with the power output of the three-phase motor (22); a control switch H (5) is arranged in the high-pressure spray lance (1); the water outlet pipe (23) comprises a water outlet pipe core (15) and a water outlet pipe lead (13); the spray lance water inlet connection (4) of the high-pressure spray lance (1) is connected with the water outlet end of the plunger pump (19) by use of the water outlet pipe core (15); the control switch H (5) is connected with the power input end of the three-phase motor (22) by use of the water outlet pipe lead (13) and is used for controlling start and stop of the three-phase motor (22). The cleaning machine with the intelligent wired controller is improved in reliability and stability of cleaning machine control operations, and convenient to operate.

Description

technical field [0001] The invention relates to the field of high-pressure cleaning machines, in particular to a cleaning machine using an intelligent wired controller. Background technique [0002] The cleaning machine includes a spray gun, a frame, a motor, a plunger pump, a water inlet pipe and a high-pressure outlet pipe. Both the motor and the high-pressure plunger pump are installed on the frame. The outlet pipes are respectively connected to the water inlet and outlet of the plunger pump, the outlet pipe is connected to the spray gun, and the spray gun is equipped with a nozzle. When in use, the motor is started, and the motor drives the high-pressure plunger pump to work. The water enters the plunger pump through the water inlet pipe, and the water After being pressurized by the plunger pump, it enters the spray gun through the water outlet, and finally sprays out through the nozzle to form a high pressure, and the dirt is peeled off and washed away to achieve the pu...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many washing machines in the market. The operator needs to turn off and start the motor frequently during the cleaning operation, and sometimes the high-pressure water gun being used is very far away from the washing machine. During this process, the cleaning machine is always in working condition, which not only wastes water, but also wastes power consumption, which is very uneconomical

At the same time, it brings difficulties to the operation of workers

[0004] Although there are gun-stop cleaning machines on the market, this kind of cleaning machine controls the micro switch by maintaining the pressure to raise the valve stem to control the motor input circuit, so as to realize the state of closing the gun and stopping the gun, and firing the gun. This is mostly used in low-pressure households. On the washing machine, its disadvantage is that the water outlet end of the washing machine and the valve section of the spray gun are in a high pressure-holding state after the gun is turned off and shut down. When leakage occurs in the pressure-maintaining section, the washing machine will be turned on and off frequently, and then the plunger pump, motor, micro-motion The failure rate of switches and other components, while maintaining high pressure for a long time has a great impact on high-pressure pipes, gun valves, etc.

In addition, there are occasional washing machines with remote control on the market. When using the spray gun with one hand and the remote control with the other hand, it is extremely inconvenient and there is a risk of loss of control.
