Detailed Introduction to ZQR Series Electric Submersible Slurry Pumps
The ZQR series of electric submersible slurry pumps is an advanced water conservancy equipment. Its motor and water pump are integrated coaxially and can work directly when submerged in the medium. The design of this series of pumps incorporates advanced international technologies and has many excellent characteristics, enabling it to play a key role in a variety of industrial fields.
I. Product Structure and Design Features
- Unique Stirring Impeller Design: In addition to the main impeller, the ZQR series pumps are equipped with a set of stirring impellers at the bottom. This innovative design can jet the sediment at the bottom into a turbulent state. In this way, even without auxiliary devices, the water pump can transport high-concentration liquid with solid particles, greatly improving the working ability of the pump under complex working conditions.
- Wide Flow Passage: The pump has a wide flow passage, which allows liquids containing solid particles such as sand, coal cinder, and tailings to pass smoothly, reducing the risk of blockage and improving the transportation efficiency.
- Compact Coaxial Structure: The coaxial integration design of the motor and water pump makes the entire pump body structure compact. It not only reduces the floor area but also reduces the difficulty of installation and maintenance. This structure can also effectively improve the transmission efficiency between the motor and the water pump, ensuring the stable operation of the pump.
II. Material Selection
- High-Wear-Resistant Materials: In order to deal with the wear of solid particles in the transported medium, the flow-through parts of the ZQR series pumps, such as impellers and stirring impellers, are all made of high-hardness high-chromium wear-resistant alloys. This material has excellent wear resistance, which can effectively extend the service life of the pump and reduce maintenance costs.
- Corrosion-Resistant Materials: Under some special working conditions, the transported medium may be corrosive. In response to this situation, corrosion-resistant materials are selected for the pump body and related components to ensure that the pump can work normally in harsh chemical environments and improve the adaptability of the pump.
III. Performance Advantages
- Powerful Sewage Discharge Capacity: With its unique structural design and wide flow passage, the pump can easily handle liquids containing a large number of solid particles. It has a strong sewage discharge capacity and can meet the needs of various complex working conditions.
- High-Concentration Transportation Capacity: The presence of the bottom stirring impeller allows the precipitated sediment to be stirred up again, achieving high-concentration transportation and improving work efficiency.
- High Operational Reliability: The unique sealing device can effectively balance the pressure inside and outside the oil chamber, maintain the pressure balance at both ends of the mechanical seal, and greatly improve the reliability of the mechanical seal, thus extending the service life of the pump. At the same time, the motor is equipped with overheat protection, and various protection devices such as water proximity detection can be added according to user requirements to ensure that the pump can operate safely for a long time under harsh working conditions.
IV. Application Fields
- Metallurgical Industry: It can be used for the removal and transportation of slurry-like liquids in metallurgical plants, such as the treatment of slag slurry.
- Mining: In mines, it can efficiently transport liquids containing solid particles such as sand, tailings, etc., meeting the drainage and slag discharge needs in mine production.
- Thermal Power Plants: It is used to treat the wastewater containing solid particles such as coal cinder generated by power plants, ensuring the normal operation of the power plants.
- River Dredging: It can be used for river dredging work, transporting the sludge, sand, and other solid particles at the bottom of the river to the designated location to improve the river environment.
- Other Fields: It is also widely used in industries such as coal, petrochemical, building materials, and municipal environmental protection to transport abrasive solid particle liquids.
