The selection method and function of automobile high pressure cleaning machine
For car lovers, the car is clean and without stains, so many car owners will have a car special cleaning machine in the trunk. With the increasing number of vehicles in the city, the parking lot is divided into ground and underground, single and double floors; Let the pressure washer into the home, become the basic household cleaning tools. But many people have doubts about the use and purchase of high pressure washing machine, especially the female comrades who have less contact with mechanical equipment. They think that the pressure of high pressure washing machine is too high, and the penetration is strong, so it is impossible to wash the car. Unclear cognition is the constraint of the development of high pressure car cleaning machine. Today, Cadbury is going to tell you about the automotive pressure washer. Car cleaning machine pressure size choice Although the car looks hard, but also can not small water force, dripping water wears through a stone is not a white word. So when choosing a car cleaning machine, the choice of pressure is very important. It is too big to scratch the paint, and too small to clean up the stains and dirt on the car. So choose the right model, experts believe that the equipment used to clean the vehicle is about 40-70 kg, the range of car cleaning function will clean the vehicle very well. Now there are some household cleaning machine pressure value in the market between 120-160 kg, during the period can also be used to clean the vehicle, but in use to regulate the size of the water pressure and water spray nozzle according to the actual situation.

Municipal sanitation and engineering with high pressure cleaning machine to do
Many people do not understand the high pressure water jet cleaning machine, there is a big misunderstanding of its ability. Some people think that the high pressure washer is just the equipment for the renovation of machinery in the factory, and some people think that the washer is just the tool for washing the car at home, and often ignore the ability of the high pressure washer. High pressure cleaning machine is divided into cold water and hot water two kinds. Life is commonly used in cold water cleaning machine, hot water cleaning machine is only used in some occasions with demand, such as restaurant pipeline oil cleaning, petrochemical plant pipeline cleaning, etc. In these areas, using a hot water high-pressure washer is far more effective than using cold water, but using a cold water high-pressure device can also be easily removed. At present, it is still cold water high-pressure cleaning. Cold water high pressure cleaning machine is subdivided into household single-phase cleaning machine and industrial and commercial dual-purpose 380V high pressure cleaning machine. These two different places and voltage equipment can be divided into convenient fuel oil cleaning machine and cleaning machine with line. These different types of high-pressure water cleaning equipment can provide cleaning and derusting services for different environments or places. Urban construction is inseparable from the green and clean environment and image. Every city attaches great importance to the sanitation of streets and public places. Basically, every area is equipped with corresponding cleaners, and strive to have no obvious paper scraps, leaves, garbage, etc. These surface garbage rely on manual or sweeper and other tools can be easily completed. More difficult dirt, manual, sweeper temporarily can not clean up.

Application of high pressure cleaner in cleaning polyester melt filter element
In the process of polyester production, the filtration accuracy of stainless steel sintered felt filter core used for polyester melt filtration is mostly in the range of 10 ~ 25 μm. The filter core is in the shape of candle, with large filtration area, high filtration accuracy, strong pollution resistance, suitable for high temperature, high pressure, high viscosity environment and other characteristics. It should be noted that the candle-shaped filter element has high cleaning requirements and is difficult to clean. In the cleaning process, alkali washing can remove organic matter, and ultrasonic cleaning can remove inorganic matter. The high pressure cleaning machine is mainly responsible for washing the inorganic residue, titanium dioxide (TiO2) and carbon black attached to the surface of the filter element, which can effectively reduce the cleaning time and improve the cleaning efficiency. In addition, improper high pressure water washing can lead to dirt washing into blocks, but reduces the cleaning effect, if the water pressure is too high, it will even break through the filter material and damage the filter element.

Application of high pressure washer in heat pipe network heat exchanger cleaning in heating industry
Scaling of heat exchanger is a common phenomenon in the thermal network system of heating enterprises. When the equipment runs for a period of time, the heat transfer surface of the heat exchanger will form scale, resulting in small thermal conductivity, thermal resistance increase, resulting in heat exchange deterioration, heat exchanger heat exchange rate is reduced, heating temperature drop, serious or even shut down cleaning, to the residential heating quality has a serious impact. Therefore, regular cleaning of heat exchanger is very necessary. The main reasons for scaling of heat exchanger in heat network are as follows: because the heat network system uses mostly tap water or groundwater, and groundwater, as the medium and long term water source of pipe network, contains a large number of inorganic salts such as bicarbonate, carbonate, sulfate, chloride, silicate, phosphate, sediment and organic matter. Bring to the production fouling, energy consumption, corrosion perforation and other hazards. Scale composition is mainly calcium hydrochloric acid and calcium phosphate, when the water contains calcium sulfate, calcium silicate, magnesium silicate, ion concentration exceeds the solubility product will also occur precipitation, deposition on the heat exchanger sheet. In order to solve this problem, most heating enterprises use chemical and manual methods to clean heat exchangers. Although the effect of chemical cleaning is good, but to consider the corrosion rate of heat exchanger control within the allowable range, in the chemical cleaning liquid to add the right amount of corrosion inhibitor and activation, infiltration, wetting additives. The operation is complicated and the cost is high. And after cleaning the chemical waste liquid is not easy to deal with, will also have an impact on the environment. And manual cleaning has low efficiency, poor effect, labor intensity and other shortcomings.
