Spiral pump, spiral mud pump, spiral activated sludge pump
1Spiral activated sludge conveying mud pumpProduct Overview
1957In the year, the screw pump was born in South America, realizing the dream of non-destructive and fully automatic transportation of live fish. As a result, the screw pump became20The great invention in the field of century water pumps.At present, it is widely used for conveying activated sludge, so we call it a spiral activated sludge conveying pump. Boyu water pumpLong term commitment to the research of spiral pumps has successfully solved the problem of traditional spiral pumps losing balance due to relatively fast wear of the centrifugal part, greatly extending the service life of the water pump and expanding the application fields of the product.BoyuSpiral pumps have become a performance indicator in difficult conveying fieldsRelatively goodThe water pump is widely used in municipal sewage treatment engineering, food processing industry, chemical industry, paper industry and other fields.Boyu Pump relies on professional pump manufacturing technology and in-depth research and development investment, as well as long-term accumulation of various screw pump engineering experience, to provide users with excellentThe engineering solution.
IICharacteristics of Spiral Activated Sludge Transport Mud Pump
Spiral mud pump and traditionalslurry pumpCompared with activated sludge conveying slurry pumps, the structural characteristics of activated sludge conveying slurry pumps determine their performance advantages as follows:
1. Large solid diameter
spiralformulaThe rotation of the impeller forms a large channel that can transport liquids containing large particles. Compared with traditional centrifugal impellers with similar outer diameters, the diameter can be greatly increased. The imported diameter is100mmThe pump can be operated with a diameter of75mmSolid particles.
2. Spiral pumps have good non clogging performance and can truly transport fiber materials without clogging
The impeller of the activated sludge conveying mud pump has a large diameter, coupled with guiding and spiral propulsion effects, making it highly capable of conveying liquids containing large particles and fibrous substances, as well as high viscosity and high concentration liquids. Especially long fiber objects can pass smoothly.
3. Spiral pump with low turbulence and flexible conveying, good non-destructive performance
The solid-liquid two-phase flow gradually advances, with no sudden change in flow direction and smooth flow. The screw pump has little damage to the transported objects and can transport live fish, vegetables, fruits, etc. Especially recently, it is particularly suitable for transporting activated sludge and can maintain the characteristics of activated sludge.
4. Energy loss and impeller wear are caused by turbulent water flow, rapid changes in flow direction, and local high flow velocity, while the impeller of the activated sludge conveying pump does not exhibit these phenomena. Therefore, it is possible to:
(1)Spiral pumps save energy and can save compared to single channel impeller pumps5%-20%Compared to vortex pumps, spiral pumps can save energy50%-60%The energy can greatly reduce operating costs;(2)Reduce pump wear, lower maintenance and repair costs, and minimize downtime.
5. Steeply slopingQ—Hperformance curve
The curve of the spiral pump is steep and inclined, and the flow rate changes very little relative to the head variation, ensuring stable operation. A typical centrifugal pump,Q—HThe curve is relatively gentle, especially for low specific speed pumps, it is difficult to achieve a steep slope in the curve.
6. No overload power curve
The power curve of the screw pump is flat, and the back of the curve sinks. During normal operation, there will be no motor overload; However, the power curve of traditional centrifugal pumps tends to rise at the back, requiring valve closure to start, and there may be motor overload issues.
7. Spiral pump high efficiency
Spiral pumps are higher than swirl pumps10%~20%, higher than ordinary impurity pumps5%~10%The efficiency is not much different from that of a typical centrifugal water pump (approximately lower)5%The efficiency of small spiral centrifugal pumps, especially on the left and right sides, can reach60%~70%Generally, small centrifugal pumps only have40%.
The hydraulic flow channel of the spiral mud pump is very smooth and the diameter is large, which reduces the recirculation of liquid in the pump. Therefore, the efficiency of the spiral pump is high, the motor power is small, the energy consumption is low, and the maintenance cost is greatly reduced.
8. The required cavitation allowance for the screw pump is low
The shutdown water level of the spiral mud pump is low, and the newly introduced pre rotation system can even extract water from the bottom of the suction tank. Even if local cavitation occurs, the pump can still work normally and can pump liquids containing gas. Spiral sludge pumps have better self-priming performance than centrifugal pumps, so they also have self-priming performance as self-priming pumps.
