Description

Technical Field

[0001] The invention belongs to the technical field of high-pressure cleaning equipment, and in particular relates to a switch control system for a high-pressure cleaning machine. Background Art

[0002] In the field of high-pressure cleaning equipment technology, traditional high-pressure cleaning machines have always faced many challenges in terms of switch control. These challenges mainly stem from the inaccuracy of the control system, slow response speed, and insufficient safety. In particular, in the pressure control of the high-pressure pump and the speed regulation of the motor, the traditional system is difficult to achieve precise matching and dynamic adjustment, resulting in unstable cleaning effects and prone to equipment failure.

[0003] Specifically, traditional high-pressure cleaners often use simple mechanical or electronic switches, which have limited control accuracy and cannot accurately adjust the output pressure of the high-pressure pump and the speed of the motor. This results in a significant impact on the cleaning effect during the actual cleaning process, and the expected cleanliness cannot be achieved. At the same time, due to the inaccuracy of the control system, the energy consumption of the equipment is also relatively high, resulting in energy waste.

[0004] In addition, the safety of traditional high-pressure cleaners is also a big problem. Due to the lack of effective safety protection devices, the equipment often cannot respond in time when abnormal conditions such as overload, short circuit or overheating occur, which can easily lead to safety accidents and cause damage to operators and the equipment itself.

[0005] Therefore, in order to solve the problems existing in the switch control of traditional high-pressure cleaning machines, improve the cleaning effect and work efficiency, and ensure the safety of the equipment, the present invention proposes a new type of switch control system for high-pressure cleaning machines.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] The following is a specific implementation of a high-pressure cleaning machine switch control system. This implementation is based on the aforementioned technical background and design ideas, and aims to achieve precise control and safety protection of the high-pressure cleaning machine through detailed steps and component configurations.

[0030] The high pressure cleaning machine switch control system of this embodiment mainly includes the following parts: a power module, a control unit, a motor controller, a sensor module, an actuator and a safety protection device.

[0031] Power module: This module is responsible for providing a stable DC voltage for the entire control system. It is usually composed of a power transformer, a rectifier circuit, and a filter circuit. It can convert the mains power (such as 220V or 380V) into the DC voltage required by the control system and ensure the stability of the voltage and current.

[0032] Control unit: As the core of the system, the control unit includes a main controller (such as a PLC or a single-chip microcomputer), an input interface, and an output interface. The main controller is responsible for executing the preset control logic and algorithm, receiving instructions from the input interface (such as the start / stop signal input by the user through the control panel) and feedback signals from the sensor module (such as pressure, flow, temperature and other parameters), and sending control signals to the actuator through the output interface.

[0033] Motor controller: Connected to the control unit, the motor controller is used to control the start, stop and speed regulation of the drive motor. It usually includes components such as a frequency converter, which can achieve precise control of the motor speed to match the output pressure requirements of the high-pressure pump.

[0034] Sensor module: This module includes at least one pressure sensor, at least one flow sensor and at least one temperature sensor. These sensors monitor the various working parameters of the cleaning machine in real time and feed the data back to the control unit. In addition, according to actual needs, the sensor module may also include other types of sensors such as liquid level sensors and current sensors.

[0035] Actuator: The actuator performs corresponding actions according to the instructions of the control unit. In this embodiment, the actuator mainly includes a solenoid valve and a pressure regulating valve. The solenoid valve is used to control the on and off of the high-pressure water flow, and the pressure regulating valve is used to adjust the output pressure of the high-pressure pump. In addition, according to actual needs, the actuator may also include other devices such as a drain valve and a safety valve.

[0036] Safety protection device: In order to ensure the safety of the cleaning machine during operation, the switch control system of the high-pressure cleaning machine in this embodiment also includes safety protection devices such as an overload protector, a short-circuit protector, at least one temperature sensor for safety protection, and an emergency stop button. These devices can respond in time when the equipment has abnormal conditions such as overload, short circuit or overheating, cut off the power supply or take other measures to prevent the accident from expanding.

[0037] 2. Workflow

[0038] The following is the working process of the high pressure cleaning machine switch control system of this embodiment:

[0039] Start-up preparation: The user should first check whether all parts of the cleaning machine are intact, and confirm that the water inlet pipe is connected correctly and without leakage. Then, switch the main switch of the control unit to the "on" position and turn on the power.

[0040] Start the cleaning machine: The user inputs the start signal through the control panel. After receiving the signal, the control unit sends a start command to the motor controller. The motor controller starts the drive motor and drives the high-pressure pump to start working. At the same time, the control unit adjusts the motor speed and the opening of the pressure regulating valve according to the preset control logic and algorithm to make the output pressure of the high-pressure pump reach the preset value.

[0041] Cleaning operation: During the cleaning process, the sensor module monitors the various working parameters of the cleaning machine (such as pressure, flow, temperature, etc.) in real time and feeds the data back to the control unit. The control unit dynamically adjusts the actuator according to the feedback signal to ensure the cleaning effect and work efficiency. For example, when it is detected that the output pressure is lower than the preset value, the control unit will send an adjustment instruction to the pressure regulating valve to increase the output pressure; when it is detected that the temperature is too high, the cooling device will be started to cool down.

[0042] Stop the cleaning machine: After the cleaning operation is completed, the user inputs a stop signal through the control panel. After receiving the signal, the control unit sends a stop command to the motor controller. The motor controller stops driving the motor and the high-pressure pump stops working. At the same time, the control unit closes the solenoid valve to cut off the water flow channel and starts the drainage device to empty the accumulated water in the high-pressure pipeline to prevent freezing or corrosion.

[0043] Shutdown and maintenance: After confirming that the cleaning machine has completely stopped working, the user switches the main switch of the control unit to the "off" position to cut off the power supply. Then, perform daily maintenance and care on the cleaning machine according to the requirements of the maintenance manual, such as checking the lubricating oil level, cleaning the filter, etc. to ensure the long-term stable operation of the equipment.

[0044] It can be seen from the above specific implementation methods that the high-pressure cleaning machine switch control system of this implementation method has the advantages of compact structure, precise control, safety and reliability, etc., which can effectively improve the cleaning effect and work efficiency and reduce energy consumption and maintenance costs.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
