ZJQ High chrome alloy vertical slurry pump

ZJQ High-chrome alloy submersible slag slurry

ZJQ submersible slurry pump is the hydraulic machinery with coaxial motor and water pump and submerged in the medium for work. The pump has advanced structure, wide flow channel, strong discharge capacity, excellent material and strong corrosion resistance.

ZJQ submersible slag slurry pump is suitable for conveying the liquid with sandstone, coal cinder, tailings and other solid particles. It is mainly used for cleaning and conveying of the slurry liquid of metallurgy, mine, iron and steel works, thermal power plant and other enterprises and is the ideal substitute pump of the traditional slurry pump.

ZJQ Submersible slag slurry pump is designed and manufactured by absorbing the foreign advanced technology. The wear-resistant material (high-chrome alloy) with high technology is adopted, so as to greatly improve pump life and reduce the repair frequency. A set of mixing impeller is added at the bottom at the water pump except for the primary impeller, which can stir the sediment sludge to eddy flow, so that high concentration convey can be realized when water pump has no auxiliary device. The unique sealing device can effectively balance the pressure inside and outside the oil chamber. So, the pressure at both ends of the mechanical seal is maintained balanced. It guarantees operation reliability of mechanical seal to the maximum limit and greatly extends the service life. If necessary, overheat protection, inlet water detection and protection and other protection measures shall be adopted for the motor, which can be in long-term safe operation at harsh conditions. Meanwhile anti-condensation, bearing temperature measurement and other preventive measures can also be added according to user’s requirements, so as to satisfy use in different occasions.

Compared with the common slurry pump, ZJQ submersible slag slurry has the following features:

1.       It is not restricted by suction lift; the slag suction efficiency is high and dredging is more thorough.

2.       It is not required to equip the auxiliary vacuum pump and the investment is more economic.

3.       It is not required to equip the auxiliary mixing device and operation is simpler.

4.       It is not required to build the complicated ground protection and fixing device when the motor is inserted under water, which is simple and convenient.

5.       The mixing /stirring impeller directly contacts the deposition surface, and the depth is controlled through the submerged depth. Therefore, concentration control more fee.

6.       The pump is directly submerged into the water for work. There is no noise or vibration and site is more tidy.

1. The power supply is 50Hz, 380V three-phase AC power supply.

2. The maximum temperature of the medium shall not be higher than 40℃, and the medium does not contain flammable and explosive gases.

3. The maximum weight concentration of solid particles in the medium: ash slag is 45%, slag is 60%.

4. The maximum submerged depth shall not be more than 20m, and the minimum submersible depth shall not be less than 1m.

5. It is better for the unit to work vertically in the medium, and the operation mode is continuous operation.

Range of performance parameters:

Flow: 30 to 1450m3/h head: 15 to 95m, the maximum particle size :92mm.
