Submersible slurry pump

Submersible slurry pumps can be widely used in mines, electric power, metallurgy, coal, environmental protection and other industries to transport slurry with abrasive solid particles. Such as slurry transportation in metallurgical concentrators, hydraulic ash removal in thermal power plants, coal slurry and heavy medium transportation in coal washing plants, river dredging, river dredging, etc. In the chemical industry, some corrosive slurry containing crystals can also be transported.

Details description

purpose

In the application range of slurry pumps, about 80% are used in concentrators in the mining industry. Due to the harsh working conditions of the ore primary selection, the service life of the slurry pump is generally low in this section. Of course, different ores have different abrasive properties.

Structure Description

I. Overview

In addition to the main wheel, a set of stirring impellers is added at the bottom of the product, which can spray the precipitated slag into a mixed liquid of water and solid particles. The pump can realize high-concentration delivery without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal is balanced, which ensures the reliable operation of the mechanical seal to the greatest extent, and greatly prolongs its service life. The motor can increase various protection devices such as water inlet detection and overheating according to user requirements, so that the product can operate safely for a long time under harsh working conditions.

Structural characteristics and working principle

ZJQ type submersible slag slurry pump is a coaxial integration of the water pump and the motor. When working, the motor shaft drives the impeller of the water pump to rotate, and transmits the energy to the slurry medium, so that it produces a certain flow rate, drives the flow of solids, and realizes the transportation of the slurry.

Its main features are as follows:

The complete-built unit is a dry motor down-pump structure. The motor is protected by a mechanical seal, which can effectively prevent high-pressure water and impurities from entering the inner cavity of the motor. In addition to the main impeller, a stirring impeller is also provided, which can stir the slag precipitated at the bottom of the water into turbulent flow and then pump it out. The main overcurrent components such as the impeller and the stirring impeller are made of high wear-resistant materials, which are wear-resistant, corrosion-resistant, non-clogging, and have strong sewage discharge capacity, which can effectively pass through larger solid particles. Not limited by the suction range, the slag absorption efficiency is high, and the dredging is cleaner. No auxiliary vacuum pump is required, and the investment is lower. There is no need to equip auxiliary stirring or spraying devices, and the operation is easier. The motor is submerged underwater, and there is no need to build complex ground protection and fixing devices, which is easier to manage. The stirring impeller directly contacts the deposition surface and controls the concentration through the diving depth, so the concentration control is more comfortable. The equipment is directly submerged into the water to work, without noise and vibration, and the site is cleaner.
