    Hot water high pressure cleaning machine As a new and advanced cleaning tool, it plays an increasingly important role in all walks of life. It is widely used in many industrial sectors and service industries. It brings great convenience to our production and life, improves the production efficiency and improves the quality of life. But in the use process, if the use method is improper, may waste a part of energy, can not give full play to its great efficiency. We should study and take appropriate measures to improve its cleaning effect and give full play to its great efficiency.
    
We should take such measures to make full use of the pressure and flow of the cleaning machine. When the high-pressure water jet is a stable and continuous water flow, the pressure acting on the cleaned object is called impact pressure. From the point of view of mathematics and physics, the impact force is directly proportional to the square of water jet velocity, so we should try our best to improve the water jet velocity at the nozzle outlet, which can effectively improve the cleaning efficiency. To make full use of the water jet velocity, we should try our best to reduce the resistance loss, winding loss, joint loss and nozzle resistance loss of the high-pressure hose. In other words, we should try our best to reduce the pressure loss in the transmission process from the high-pressure pump to the nozzle. It is necessary to make full use of water jet power, that is, the total working capacity of water jet, which is directly proportional to the pressure and flow rate of water jet. It can be seen from this that the power of water jet can be improved by increasing the pressure and flow rate of water jet. The pressure of the cleaning machine is calculated and designed according to the strength of the dirt caking. When the pressure of the hot water high-pressure cleaning machine is sufficient, we should try to improve the flow rate of high-pressure water jet, so as to increase the cleaning effect. Is to design a suitable nozzle diameter, to make the high-pressure nozzle aperture is very good, to ensure the full play of the pressure and flow of the cleaning machine, that is, the high-pressure pump of the cleaning machine can always work under the rated pressure and rated flow conditions, and play a great efficiency.
 
The spray gun of hot water high-pressure cleaning machine does not spray water. The possible reason is that the water inlet and water inlet filter are blocked. The nozzle is blocked and the heating spiral tube is blocked. If necessary, remove the scale. The outlet pressure is unstable and the water supply is insufficient. The air suction pipeline is caused by pipeline rupture and the detergent nozzle is not inserted into the cleaner. Nozzle wear, high pressure water pump seal leakage. The burner does not ignite and burn, the air inlet is insufficient, and white smoke is emitted. The fuel filter, fuel pump and fuel nozzle are dirty and blocked. The solenoid valve is damaged, the position of ignition electrode is changed, and the spark is too weak. The high pressure ignition coil is damaged and the pressure switch is damaged.
    
Hot water high-pressure cleaning machine has the above problems, the user can find out the causes and eliminate the fault. However, if the pump body leakage, crankcase oil leakage and other serious faults occur in the hot water high-pressure cleaning machine, the cleaning machine should be sent to the professional maintenance department with complete accessories and strong technical force for repair, so as to avoid unnecessary economic losses.
    
  The cleaning method of using hot water high-pressure cleaning machine to clean the heat exchanger is as follows: first, remove the head and tail of the heat exchanger to expose all the tubes, then insert the rigid spray gun or flexible high-pressure spray gun into the pipe hole 200-300 mm away, open the spray gun control valve to pressurize the high-pressure water until it reaches the rated pressure. Then, in the cleaning process, gradually make the spray gun deep into the pipe Push until the high-pressure water jet ejects from the other end of the heat exchanger. After that, the operator slowly draws back the spray gun in the working state, and the scale continues to be broken until the spray gun is pulled back to the nozzle when it is sent in, and then the scale is gradually discharged from the pipe. After that, the same method is used to clean the tubes one by one until the tube side of the whole heat exchanger is cleaned.
   
When using hot water high-pressure cleaning machine for operation, the important parts include pipe cleaning nozzle. The jet generated by the back jet nozzle peels off the dirt on the pipe wall and generates forward thrust and backward return to push the nozzle forward for cleaning. In the cleaning process, we need to pay special attention to the normal work of the nozzle, so as not to cause damage to personnel or machines. First of all: before construction, the nozzle should be carefully checked whether there is blockage, if found, it should be treated in time. Secondly, the nozzle for pipeline cleaning should be carefully designed and manufactured. The nozzle should be evenly distributed on the circumference of the nozzle, and the aperture and inclination angle are completely equal. The main function is to realize the reaction force of balance. Each time we use the hot water high-pressure cleaning machine, we need to put the nozzle into the pipe about 30cm, and then pressurize the nozzle to make it enter the pipeline. When the nozzle is pulled out of the pipeline after cleaning, we need to adjust the pressure of the high-pressure pump to zero, so as to avoid the situation that the sprinkler head forms a water hose and injures the operators.
