Selection and Lifespan of Spray Nozzles for High-Pressure Cleaning Machines

　　Nowadays, high-pressure cleaning machines have been widely used in many manufacturing industries, and their development trend in China is rapidly strengthening. With their high efficiency, low project investment, and minimal environmental pollution, they have gained recognition in every manufacturing industry. In oil and gas storage and transportation manufacturing industry, the explosion-proof feature of high-pressure cleaning machine seems to be crucial. What are the actual advantages of explosion-proof high-pressure cleaning machine of SINPO machinery in this regard?

No pollution to the environment

　　After long-term application of oil and gas storage and transportation systems, such as cargo ship holds, railway freight cars, highway freight trucks, and oil tanks, they must be cleaned. However, the explosion-proof high-pressure cleaning machine does not require other organic chemical preservatives, using only cold water for cleaning. With the ideal cleaning effect achieved by ultra-high-pressure cleaning machine, it is less likely to cause other adverse effects on the natural environment. At the same time, it has the characteristic of low noise, which also reduces the risk of flames that could cause discomfort and pollution.

Reliable

　　During the traditional cleaning process, it is necessary to clean with fire or electricity. However, the risk factor is very high, and there is a possibility of accidents even with slightly less strict adherence to safety and reliability standards. In contrast, explosion-proof high-pressure cleaning machine is less likely to cause other flames during the entire cleaning process, ensuring safety and reliability throughout the stable process.

High cleaning efficiency

　　Many people feel that cleaning effect of high-pressure cleaning machine is not ideal because it does not use other organic chemical cleaning equipment. In fact, high-pressure cleaning machine uses the basic principle of high pressure, and can work in multiple directions with automated technology. Critical areas can be cleaned thoroughly, resulting in a highly efficient cleaning effect.

　　Nozzles for high-pressure cleaning machines are the components that directly convert high-pressure water jet energy, and therefore, they are the most vulnerable parts of high-pressure cleaning machine. Each cleaning department of machine hopes that nozzle has a longer lifespan to reduce cleaning costs and frequency of nozzle replacement. The lifespan of spray nozzle mainly depends on material selection, processing quality, and hardness treatment.

　　Material selection. The choice of material is directly related to the pressure of high-pressure water pump. For low-pressure cleaning machines below 10MPa, brass or bronze can be used as materials, while stainless steel or carbon steel is usually chosen for medium and high-pressure cleaning machines from 15-100MPa. For ultra-high-pressure cleaning machines above 100MPa, hard alloys, synthetic gemstones, and diamonds are commonly used as nozzle materials.

　　Hardness improvement. When making nozzles with stainless steel and other steel materials, steel materials above medium carbon should be selected, and their surface hardness and wear resistance should be improved by quenching and tempering, thereby increasing their lifespan.
