The QSZ submersible slurry pump is a hydraulic machinery designed, researched and developed by our factory's technical personnel to absorb advanced technologies from both domestic and foreign sources, combined with the actual situation of a large number of users. The motor and water pump are coaxially integrated and work in the medium. This product has excellent material selection, advanced structure, wide flow channel, and strong passing capacity. It is used by enterprises such as metallurgy, chemical industry, mining, and thermal power plants to transport liquids containing solid particles such as sand and gravel, coal slag, and tailings. It is an ideal alternative to traditional slurry pumps.

In addition to the main wheel, this product also adds a set of stirring impellers at the bottom, which can spray the settled slag into a mixed liquid of water and solid particles. Enable the water pump to achieve high concentration transportation without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, ensuring that the pressure at both ends of the mechanical seal remains balanced, maximizing the reliable operation of the mechanical seal and greatly extending its service life. The motor can add multiple protection devices such as water inlet detection and overheating according to user requirements, enabling the product to operate safely for a long time under harsh working conditions.

2、 Structural features and working principle

The QSZ submersible slurry pump is a coaxial combination of a water pump and a motor. During operation, the motor shaft drives the impeller of the water pump to rotate, transferring energy to the slurry medium to generate a certain flow rate, which drives the solid flow and achieves the transportation of the slurry.

Its main characteristics are as follows:

1. The whole machine is a dry motor pump type structure. The motor adopts mechanical seal protection, 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 that can stir the sediment at the bottom of the water into turbulence and extract it.

3. The main flow components such as impellers and mixing impellers are made of highly wear-resistant materials, which are wear-resistant, corrosion-resistant, unobstructed, and have strong drainage capabilities. They can effectively pass through larger solid particles.

4. Unrestricted by suction distance, high slag suction efficiency, and more thorough dredging.

5. No need to equip an auxiliary vacuum pump, lower investment.

6. No need for auxiliary mixing or spraying devices, making operation easier.

7. The motor can be submerged underwater without the need for complex ground protection and fixed devices, making management easier.

8. The stirring impeller directly contacts the sedimentation surface and controls the concentration by diving depth, making concentration control more flexible.

9. The equipment operates directly underwater without noise or vibration, making the site cleaner.
