The comparison with similar products is as follows

The heart of high-pressure water cleaning machine - pump

Our company uses a crankshaft driven three cylinder ceramic plunger pump produced by the Italian Aino Group, which differs from some pumps used by other companies in that:

1.1Power end: Compared with the unstable performance of domestic pumps, the power end of Aino pumps is maintenance free and does not require frequent replacement of important components such as crankshafts, bearing shells, and bearings;

1.2Plunger: The important component of a plunger pump is the plunger. Compared with domestically produced stainless steel plungers that are not wear-resistant, the Aino pump uses ceramic plungers with good wear resistance and excellent straightness.

2Filtering system

The filtration system is a very important factor affecting the performance and service life of high-pressure water machines. Through market research and years of understanding of the domestic and international cleaning machine industry, we have learned that the high failure rate of many high-pressure water machines is caused by the "unsuitable environment" and easy damage characteristics of the filtration system. Our company has specially developed a stainless steel filter to address the differences in water quality between China and foreign countries. It uses original foreign filter materials and is equipped with a stainless steel structural cover, greatly reducing the high cost of completely importing filter bags. At the same time, it effectively reduces the failure rate of high-pressure water cleaning machines. This product has been widely used in our company's products.

3Shutdown protectionTSsystem

In our investigation of the usage of many cleaning machine users, we found that some operators often only release the trigger of the high-pressure gun they are using and do other things while using the cleaning machine. The cleaning machine that is not turned off runs for a long time without human supervision, providing conditions for untrained personnel to come into contact with high-pressure cleaning machines and creating potential accidents; At the same time, prolonged air operation also increases the temperature of residual water inside the water machine, which has a negative impact on the sealing life of various components.

Our company has introduced and absorbed foreign shutdown protection technology, and installed shutdown protection devices in the equipment. After releasing the trigger for a period of time, the equipment automatically starts the shutdown protection function. After the operator returns, the switch is activated for operation.

The general setting time is2-10minute.

4Protection settings for unloading pressure regulating valves and safety valves

The unloading pressure regulating valve itself has the function of a pressure regulating valve, which is to regulate the pressure of the water system; At the same time, it can also relieve the pressure on the pump head when turning off the gun, greatly extending the service life of the pump. The setting of a safety valve is the safety protection and barrier of a high-pressure cleaning machine. When the pressure in the water system exceeds the set value, it will automatically trip and quickly release pressure, causing the pressure in the water system to quickly drop to zero, effectively protecting the personal safety of the operator. At present, some imported equipment in China is not equipped with safety valves, which poses a hidden danger to safety production.

5High pressure hose

At present, our company adopts multi-layer mixed weaving technology for steel wire pipes. We cooperate with professional pressure hose manufacturers and combine the advantages of high-pressure hoses at home and abroad to develop products for high-pressure and ultra-high pressure cleaning. These products have the characteristics of high safety, strong professionalism, and long service life.

6Electrical protection

Our high-pressure water cleaning machine has relatively complete electrical protection. This includes: overload protection, short circuit protection, phase loss protection, leakage protection, protection against excessive start-up time and stalling time24VSafety control voltage.

7. Water shortage protection

From the perspective of ergonomics, this product fully considers that when the equipment is short of water, the high-pressure pump will be in idle operation, which will greatly shorten the service life of the high-pressure pump. In response to the above phenomenon, a water tank has been installed on this machine, and a water shortage protection system has been set up to effectively prevent the aggravation of wear caused by dry wear due to water shortage. Many imported devices are not equipped with water tanks and do not have water shortage protection functions.
