Congratulations! Hongxing series high-pressure water cleaning machine system applied for the Provincial Science and Technology Achievement Award

High-pressure water jet cleaning technology is a high-tech cleaning technology emerging internationally in recent years. High-pressure water jet cleaning has the characteristics of low cleaning cost, fast speed, high cleaning rate, no damage to the object to be cleaned, wide application range, and no environmental pollution. Since it was introduced into our country in the mid-1980s, it has gradually gained the general recognition and attention of the industry.

There are dozens of cleaning technologies used in traditional cleaning operations, including mechanical drilling cleaning, steam cleaning, chemical cleaning, ultrasonic cleaning, and water jet cleaning. Western developed countries such as Japan, Europe and the United States mainly used chemical cleaning methods before the 1970s, and began to develop high-pressure water jet cleaning technology since the end of the 1970s. So far, high-pressure water jet cleaning has become the mainstream cleaning technology in western developed countries, accounting for more than 80% of the cleaning industry market share. In the United States, high-pressure water jet cleaning has accounted for 90% of the cleaning industry.

The cleaning industry in my country has been in the backward state of chemical and manual cleaning for many years. It is estimated that 80% of the industrial cleaning of high-pressure cleaners in my country is currently done by chemical methods. Whether it is chemical cleaning or manual cleaning, there are problems such as high cleaning cost, low efficiency, and environmental pollution, which are far from meeting the growing industrial and civil cleaning requirements of modern society.

After the high-pressure water jet cleaning technology was introduced into my country in the mid-1980s, it was rapidly popularized in the mid-1990s. At present, high-pressure pump water jet cleaning has exceeded 10% of my country's industrial cleaning, and it is growing rapidly. With the continuous improvement of the efficiency, cleanliness rate and environmental protection requirements of the cleaning industry in modern society, the popularization and application of high-pressure water jet cleaning technology in our country is an inevitable trend.

1. Characteristics of high-pressure water jet cleaning technology

"High-pressure water jet" refers to pressurizing water to hundreds of atmospheric pressures through a high-pressure water generating device, and then converting it into a high-speed fine "water jet" through a spray device with a small aperture. The speed of this "water jet" is generally more than twice the Mach number, has huge striking energy, and can complete different types of tasks. The technology of using this highly concentrated water jet to complete various cleaning operations is called "high-pressure water jet cleaning technology".

High-pressure water jet cleaning is a physical cleaning method. Compared with traditional manual, mechanical cleaning and chemical cleaning, it has the following advantages:

①The pressure and flow rate of the water jet can be adjusted conveniently, so that the substrate of the object to be cleaned will not be damaged.

②High-pressure water jet cleaning will not cause secondary pollution. If there is no special requirement after cleaning, no cleaning treatment is required.

③ Wash objects with complex shapes and structures, and can perform cleaning operations in places with narrow spaces or harsh environments.

④ High-pressure water jet cleaning is fast and thorough. For example: the cleaning rate of the sewer pipe is 100%, and the cleaning rate is over 90%; the cleaning rate of the heat exchanger is over 95%; 3 minutes.

⑤The cleaning cost is low, only about 1/3 of the chemical cleaning, that is, the high-pressure water jet cleaning of the plunger pump is a fine jet. In the case of continuous and uninterrupted, the water consumption is 1.8-4.5m3/h, and the power is 35-90KW Left and right, belong to energy-saving equipment.

⑥ High-pressure water jet cleaning is widely used. Wherever the water jet can directly hit, no matter it is the inner cavity of pipes and containers, or the surface of equipment, no matter it is hard scale or solid blockage, it can be quickly separated from the bonding matrix and cleaned thoroughly. High-pressure water jet cleaning has no special requirements on the equipment material, characteristics, shape and type of dirt, only that the water jet can achieve it.

⑦Different from chemical cleaning, high-pressure water jet cleaning has no harmful substance discharge and environmental pollution problems. After the water jet is materialized, it can also reduce the air dust concentration in the work area and protect the environment.

The cleaning industry has always been an indispensable part of industry and civil use. Compared with other cleaning methods, high-pressure water jet cleaning has incomparable advantages in cleaning effect and efficiency, cleaning cost, and environmental protection, and its popularization and application is an inevitable trend.

2. Cleaning of large diameter pipes

For pipes with a diameter of ≤Φ800mm, ordinary spraying devices, such as self-propelled nozzles, can be used to dredge and clean manually. For pipelines above Φ800mm, due to the limitation of spraying distance, it is necessary to develop a special cleaning mechanism and slag discharge mechanism according to its diameter specifications. The key technologies are:

①For pipelines of Φ800mm-Φ2000mm, the key technology is the development of two-dimensional rotary cleaning device and traveling mechanism, and its traction power is generally steel wire rope traction.

②For pipelines above Φ2000mm, such as large reinforced concrete pipelines with a diameter of 7.3m, it is generally necessary to develop a self-propelled mechanism for a two-dimensional rotary cleaning device.

This research will use the Hongxing series high-pressure water jet cleaning system as a platform. In addition to completing general cleaning tasks, it will also complete the mechanized and semi-automatic cleaning of super-large diameter straight pipes and curved pipes.
