Description

Technical Field

[0002] Pneumatic pump pressurized water-gas dual-purpose cleaning machine is a highly efficient and multifunctional cleaning equipment. It combines pneumatic pump pressurization technology and water-gas two-phase cleaning method. It is widely used in cleaning work such as industrial pipelines and equipment surfaces. The working principle of pneumatic pump pressurized water-gas dual-purpose cleaning machine is mainly based on pneumatic pump pressurization technology and water-gas two-phase cleaning method. The pneumatic pump is driven by compressed air to generate high-pressure water flow. At the same time, it is combined with a gas pulse generating device to make the air act on the water flow in the form of pulses of a certain frequency to form a water-gas two-phase mixture. This mixture produces a strong scouring effect on the surface of the pipeline or equipment, effectively removing dirt, grease and other impurities.

[0003] Currently, cleaning machines on the market are divided into two types: electric and fuel-powered. Electric cleaning machines, if the circuit insulation is poor or the sealing is not tight during use, will cause the circuit to come into contact with water vapor, there is a risk of equipment short circuit and electric shock to personnel; fuel-powered cleaning machines are subject to the risk of mechanical injury when in use, and the internal combustion engine may cause sparks to come out of the exhaust pipe due to mechanical failure during the working process, which is not conducive to the special use environment of fire prevention and explosion prevention.
