Simple and compact structure: the screw pump adopts single-head threaded design without axial force, so its external dimensions are small and lightweight, which can be applied to a variety of harsh working conditions and environmental requirements. In addition, its transmission mode is a continuous rotary movement of the meshing rotary type, without the need for couplings and other auxiliary devices to support the entire rotor parts, easy to operate and maintain.
High efficiency: under the same pressure, the screw pump has higher working efficiency than piston reciprocating and plunger hydraulic motor. At the same time, due to its special structure and design, the screw pump is particularly advantageous in conveying high-viscosity substances, effectively avoiding cavitation, backflow and other problems in the process of fluid pumping, so that the flow rate and pressure are stable.
Small internal cavity flow loss: compared with other types of pumps such as centrifugal pumps and gear pumps, screw pumps have smaller internal cavity flow loss, which means less energy waste and more efficient work.
Smooth operation: Screw pumps operate through internally ground gears and operate incredibly smoothly, with virtually no vibration.
Low noise: the noise generated when the screw pump is running is very low compared to other pumps, especially compared to gear pumps, its operation is softer, less pulsation, less noise, less vibration, which helps to extend the service life of the equipment.
strong adaptability of the medium: screw pumps are adaptable to the medium, not easy to produce clogging abnormalities, suitable for a variety of high viscosity, high temperature, easy to crystallise, corrosive liquid transport. It can transport all kinds of chemical substances, crude oil, petroleum, detergent, paint, pigment, synthetic resin, etc., as well as all kinds of acid, alkali, salt, organic solvents and other corrosive liquids.
Strong suction capacity: screw pump has better suction capacity, so it works better in longer pipelines, higher viscosity oil and when there is air in the fluid.
Ⅴ. Long service life
Long service life: Because screw pumps operate with less friction and have a simple internal structure, they are less susceptible to wear and tear, so they have a long service life. Regular maintenance of the pump and replacement of worn parts can further extend the life of the screw pump and keep it running efficiently.
