China Slurry Pump - introduction of submersible slurry pump
It can be widely used in mining, power, metallurgy, coal, environmental protection and other industries to transport abrasive slurry containing solid particles. Such as metallurgical beneficiation plant slurry transportation, thermal power plant hydraulic ash removal, coal washing plant coal slurry and heavy medium transportation, dredging rivers, river dredging, etc. In the chemical industry, some corrosive slurries containing crystals can also be transported.

China Slurry Pump - introduction of submersible slurry pump
About 80% of the application range of slurry pumps is used in mineral processing plants in the mining industry. Due to the poor primary ore selection conditions, the service life of the slurry pump is generally low in this section. Of course, different ores have different abrasive properties.

Although the use of submersible slurry pumps is extensive, the correct application is very important. Due to the limitations of the name of the slurry pump, some people in this industry have misunderstood this. In fact, the impurity pump, dredging pump, dredging pump, etc. are all in the application range of slurry pump. In the application process of slurry pump, it is necessary to pay attention to reasonable design, correct calculation, and proper selection. These points are very important.
I. Overview
In addition to the home wheel, this product adds a set of impellers at the bottom, 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, ensuring the reliable operation of the mechanical seal to the greatest extent, and greatly extending its service life. The motor can increase water detection according to user requirements. Various protection devices such as overheating enable the product to operate safely for a long time under harsh working conditions.

2. Structural characteristics and working principle
The China submersible slurry pump is a coaxial pump and motor. During operation, the motor shaft drives the pump impeller to rotate, transferring energy to the slurry medium, causing it to produce a certain flow rate, driving solids to flow, and achieving slurry transport.
Its main features are as follows:
The whole machine is a dry-type motor under pump structure. The motor is protected by a mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, there is also a stirring impeller, which can agitate the slag deposited on the bottom of the water to extract it after turbulent flow. The main flow components such as impeller and mixing impeller are made of highly wear-resistant materials, which are resistant to wear, corrosion, non-clogging, and have a strong sewage discharge capability, and can effectively pass larger solid particles. It is not limited by the suction stroke, the slag suction efficiency is high, and the dredging is more thorough. No auxiliary vacuum pump is needed, and the investment is cheaper. No auxiliary stirring or spraying device is needed, and the operation is simpler. The motor dives into the water without the need to construct complex ground protection and fixing devices, making management easier. The stirring impeller directly contacts the deposition surface, and the concentration is controlled by the dive depth, so the concentration control is more free. The equipment works directly under water without noise and vibration, and the site is cleaner.
When the slurry pump is working, the pump needs to be placed on the land, the suction pipe is placed in the water, and the irrigation pump needs to be started. Due to structural constraints, the mud pump and submerged slurry pump need to be placed above the water surface during operation. The pump must be placed in the water, so it must be fixed. Otherwise, the motor will fall into the water and the motor will be scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is cumbersome, and the application occasions are subject to many restrictions.
If there are spare pumps, it is best to use the two pumps alternately. If the stuck pump only needs to repair the pump, you can add a net at the water inlet to prevent too many impurities from entering the pump, so the chance of stuck pump will be much smaller!
The pump should be divided into two aspects: electricity and machine. For the machine, the previous maintenance records are mainly transferred out and compared to know. The second is the electrical aspect. It is necessary to understand the power of each pump motor and have a certain understanding of his control system. Slurry pumps with mechanical seals must ensure the supply of shaft seal water. It is strictly forbidden to run without water, otherwise the mechanical seal will burn out.
Selection design editor
The selection design of the submersible slurry pump has a great influence on the service life and operating stability of the slurry pump. A scientific and reasonable selection design will affect whether your slurry pump can achieve the best and efficient operation.
The slurry pump with high efficiency has three characteristics:
1, the operating efficiency of the slurry pump is very high and the loss is low.
2, the over-current components of the pump have a relatively long service life, saving production costs.
3, the entire industrial and mining system operates stably, and will not affect the work of the entire industrial and mining system because of pump operation problems.
4, the selection parameters: water outlet diameter, flow rate, dust, motor power, impeller speed, pumping rate, maximum particles, weight.
