Advantages of rotor lobe pump used in mine well point drainage system
When mining a mine, the groundwater in the mine needs to be discharged in time by pumping equipment. The well-point drainage method is a construction method that can continuously pump and drain groundwater. The well point construction method is a construction method in which a series of well points are buried below the groundwater surface at intervals of 1 to 2 m, and the groundwater is forcibly sucked by using self-priming pumps or vacuum pumps. The sucked water is collected from the suction pipe through the rotary joint in the well point main pipe for drainage. The traditional well point drainage system mostly uses vacuum pumps, but after the vacuum pump satisfies the suction function, there are also many drawbacks, and the speed of vacuum formation is slow; working noise Large; In addition, when the vacuum pump is working, it needs to be fitted with one or more vacuum tanks. The complicated system and large space occupation are very unsuitable for non-stationary construction sites such as mining.
As a kind of pump equipment with strong self-priming and low noise, the rotor pump is mostly used in the well point drainage system. Its specific advantages are as follows:

Strong self-priming ability
In terms of self-priming performance, thanks to the ingenious design principle (the medium is filled in the sealed space in the pump cavity and pumped along with the movement of the sealed space), the lobe rotor pump can form a vacuum in a short time without requiring With the vacuum tank, there is no need to inject liquid into the pump cavity during the start-up time; the self-priming height can reach 9 meters water column.
Portable or mobile
In terms of portability, the lobe rotor pump can be driven by a diesel engine, eliminating the driving obstacles of outdoor operation without power supply: At the same time, Saiken Pump also designed a semi-mobile well point drainage pump system, after the pump is connected to the drive system They are installed together on an integral base with pulleys under the base and a lifting frame at the top to facilitate the transfer of pump equipment to different places of use.
Strong wear resistance
The lobe rotor pump can handle up to 85% solid content grinding mud, and can replace centrifugal slurry pumps, hose pumps, diaphragm pumps, etc. Compared with hoses and diaphragm pumps, the lobe rotor pump has a large flow range and a high pressure level, and Ensure stable transportation without pulsation.

Advantages of lobe rotor pump

Comparison of lobe rotor pump and centrifugal pump
1. The pump cavity of the rotor lobe pump is large in volume, which is suitable for conveying the medium with high viscosity and high solid content. The centrifugal pump transports the medium. Once the medium becomes viscous, the flow or pressure will drop sharply.
2. The lobe rotor pump is an elastomer rotor, which has good flexibility and wear resistance, can achieve mixed gas-liquid-solid transportation and is resistant to cavitation. The centrifugal pump is a metal impeller, which can only transport relatively clean and fluid materials, and cannot mix gas, liquid and solid.
3. The lobe rotor pump adopts a three-lobe rotor with a spiral line, with small pulsation, low shear, and stable delivery. The speed of centrifugal pumps is generally very high, up to thousands of revolutions per minute, which is very shearing to the medium.
4. The lobe rotor pump is easy to maintain and can be repaired online. In addition, the back cover of the lobe rotor pump can be repaired without disassembling the pump body and pipeline. The centrifugal pump needs to be disassembled and repaired.
5. Comparison of lobe rotor pump and screw pump
6. Conveying directionThe conveying direction of the lobe rotor pump can be reversed, and the pump has a completely symmetrical structure; The screw pump cannot be reversed, and the seal is under pressure when it is conveyed in the reverse direction.
1. Service lifeThe wear parts of the lobe rotor pump have a long service life, and the wear on the flow parts mainly comes from the abrasive and corrosive components in the medium. The service life of the screw pump is low. The friction between the rotor and the stator, the particulate matter in the medium, etc., simultaneously affect the service life of the wearing parts. The stress generated by the eccentric rotating rotor is all borne by the stator, which intensifies the wear between the parts, even if it is When transporting media without any particulate matter, the stator of the pump will gradually wear out.
1. Spare parts costThe cost of spare parts for the lobe rotor pump is very low. The patented adjustable rotor and replaceable rotor tip of the lobe rotor pump minimize the cost of spare parts. The cost of replaceable liners and mechanical seals is also very low. The cost of accessories only accounts for 10% of the whole pump~ Around 15%. The cost of spare parts for screw pumps is very high. Due to the fierce price war between screw pump manufacturers, it is not profitable to sell the whole pump. Now the profits of screw pump manufacturers mainly come from the sales of accessories. An extreme example is the price of a set of accessories. Higher than the price of the whole pump.
1. Maintenance The maintenance of the lobe rotor pump is very easy, no need to disassemble the pipeline, few special tools, small space, and small manpower. It is not easy to repair the screw pump. Every maintenance needs to be disassembled and removed. The universal joint, stator, rotor and other parts must be disassembled with special tools. The repair work requires a large space to complete, and more than 2 people can complete the maintenance. Work.

What are the differences between lobe rotor pumps and gear oil pumps

The difference in working principle 　　

lobe rotor pump

The work of the rotor lobe pump relies on two synchronized rotors, and even a synchronized rotor rotates in the opposite direction. Because the two rotors are synchronized and rotate in the opposite direction, a strong force will be generated at the inlet and outlet of the cam rotor pump. Suction force sucks in the material to be conveyed.

gear pumps

The gear oil pump relies on a pair of identical gears in the pump body to operate, and the gears stand side by side in the pump. The two gears will generate negative pressure on the suction surface of the operation. This negative pressure will suck the liquid into the pump body. The inhaled liquid gradually increases and the discharge surface generates high pressure, and the liquid will be ejected out of the pump body.
