  as everyone knows, High pressure cleaning machine With its advantages of environmental protection, high efficiency and cost saving, the equipment has been widely used in chemical equipment, boilers, buildings, highways, locomotives and other fields. For example, it takes only a few minutes for the high-temperature cleaning machine to remove the asphalt, and it does not need to be manually removed; the high-pressure cleaning machine for removing the oil dirt, rust layer and paint of the equipment has an immediate effect; building roughing, roughing and cutting The efficiency of high-pressure cleaning is dozens of times higher than that of manual and traditional tools, and it will not affect the environment.
At present, the structure of domestic high-pressure cleaning machine is roughly divided into three parts: high-pressure pump, driving power and cleaning device. Its core is high pressure pump.

    
General industrial high-pressure cleaning machine is equipped with three plunger high-pressure pump. The plunger and crankshaft of high pressure pump are the key parts with high machining accuracy. The crankshaft is used to transmit driving force to push the plunger stroke to high pressure, which enters into the nozzle of cleaning device through high-pressure rubber hose to form high-pressure jet to act on the cleaning object. There are a series of sealing rings on the plunger of the pump. The machining accuracy of these rings is high, which plays an important role in maintaining stable pressure. The flow controller in the pump assembly is composed of a spring loaded permanent-magnet piston and a reed tube. When the water through the pump pipe is insufficient, the water magnetic piston drops and the contact of the reed tube is disconnected to avoid overheating of the pipeline. When using the high-pressure cleaning machine, it should be very careful to adjust the different pressure and flow, according to the direction marked on the high-pressure pump. Generally, turning the adjustment knob clockwise will increase the pressure and increase the flow rate. When adjusting the pressure anticlockwise, the pressure will decrease and the flow rate will decrease. Generally, the nozzles with different apertures will also affect the pressure and flow. Generally, the small aperture will be selected for high pressure and low flow On the contrary, the nozzle with large aperture is selected.
  
High pressure pump is the key component of high-pressure cleaning machine. It should be maintained regularly in strict accordance with the operation and maintenance instructions, so as to prolong the service life of the high-pressure cleaning machine and not delay the construction period.
1. The lubricating oil of the corresponding model should be replaced in the oil tank of the pump body according to the instructions. After the oil tank is cleaned, the new oil is injected.
2. The joint of crankshaft and plunger connecting rod is often damaged in high-pressure pump. Most of the reasons are that the oil is not pure, there are impurities mixed into the bearing bush, and the bearing bush bolt falls off, causing the bearing bush to wear
3. The lubricating oil should be replaced and checked regularly to avoid the oil quality being too dirty or the oil level too low
4. If the red plunger is worn and the plating surface is damaged during high-pressure cleaning, it should be re polished.
5. In the process of use, the regulating parts and electrical components of the high-pressure pump should be carefully protected to ensure the normal operation of the production. The high-pressure pump body should be disassembled and inspected regularly to remove the remaining impurities in the box to avoid damage to the plunger and sealing ring.
Therefore, in the purchase of industrial high-pressure cleaning machine to recognize the brand and parameters of high-pressure pump.
