1. The whole machine is a dry pump type, the motor adopts the oil chamber sealing method, and there is a mechanical seal inside, which can effectively prevent high-pressure water and impurities from entering the motor cavity.
2. In addition to the main impeller, there is also a stirring impeller, which can stir the sludge deposited on the bottom of the water into a turbulent flow and then extract it.
3. The impeller and stirring impeller and other over-current components are made of high-hardness high-chromium cast steel, which is wear-resistant, corrosion-resistant, and has strong sewage discharge capacity, and can pass through larger solid particles.
4. The motor is submerged underwater, not limited by the suction stroke, with high slag suction rate and more thorough dredging.
5. The overall equipment is simplified, no auxiliary stirring device or spray device is allowed to operate, and the total investment of the unit is reduced.
6. The stirring impeller is directly close to the deposition surface, and the concentration is controlled by the diving depth. In the case of a large proportion of the medium, the concentration of the medium can be increased by adding auxiliary devices.

1. The power supply is 50Hz/380V three-phase AC power supply, and the capacity of the distribution transformer is 2-3 times the rated capacity of the motor.
2. The temperature of the medium should not exceed 60°C, and it does not contain flammable and explosive gases.
3. Large weight concentration of solid particles in the medium: 45% for ash and 60% for slag.
4. The diving depth of the unit: no more than 40 meters, and the small diving depth is subject to submerged motors.
5. The working position of the unit in the medium is vertical, and the upper part is suspended and positioned.
6. The maximum diving depth of the crew is not more than 20 meters, and the minimum diving depth is not less than 1 meter.
