Working principle of NM090BY01L06B screw pump

Based on the rotation of the screw and the movement of the helix. When the main screw rotates, it draws the liquid from the inlet into the pump body, compresses the liquid, and pushes it to the outlet along the helix. As the screw rotates, the liquid is compressed, resulting in high pressure at the pump outlet. Since the bulge of the screw pushes the liquid along the helix, a continuous closed space is formed inside the rotor, and the liquid is continuously compressed and discharged in this space.

Advantages of NM090BY01L06B

Transmitting difficult-to-transmit liquids
Can transmit high-viscosity liquids, liquids containing solids or bubbles, high-concentration mud, and other liquids that cannot be smoothly transmitted by previous pump products.

Ensure that the liquid does not deteriorate during the transmission process
Can transmit highly perishable substances such as whipped cream, polymer coagulants, and cake materials.

Pulsation-free quantitative transmission
There is no pulsation during discharge, so quantitative transmission can be achieved according to the set value. And the discharge volume can be freely controlled by adjusting the rotation speed.

Control the rotation speed and change the discharge volume instantly
Since a fixed amount of the transmission material will be discharged every time the rotor rotates once, the discharge volume can be changed instantly by changing the motor rotation speed.

Energy-saving and silent technology is used to reduce noise and odor
Since no other driving sounds are emitted when the transmission object moves in the pipe except the sound of the motor running, it can ensure that there is basically no noise and no odor.

Wide range of applications, not affected by capacity, pressure, and liquid quality
The material has characteristics such as wear resistance and drug resistance. Therefore, it can transmit drugs such as sulfuric acid and sodium hypochlorite.

Check the oil level and oil condition (if the pump is oil-lubricated) and change the oil as needed. Clean the pump and its components regularly. Inspect the seals, gaskets, and bearings for wear and replace them as needed. Check the alignment of the pump and its coupling and adjust if necessary.

A screw pump is self-priming, meaning this process doesn’t need to take place. This is because of the vacuum that is created within the pump. If a screw pump does become dry and continues to be used, it will cause damage. Eventually, dry running a screw pump will leave it irreparable.

Smooth flow and low turbulence produced by the centrifugal screw impeller keep hydraulic losses to a minimum. The pump is able to handle large soft solids with efficiencies of more than 80%, whereas standard solid handling pumps normally run around 35%-50% efficiency.
