Universal three-screw pump with wide application
1.The screw units is rotating along with the external prime mover.
2.The spiral groove of the screw opens periodically,and the volume of suction cavity increases,resulting into a vacuum.
3.The medium is absorbed into the spiral groove and sealed in the spiral groove.
4.Along with the rotation of screw,the medium moves toward the outlet along the axial line of the screw.
5.The medium is pumped out.This is the operating principle of screw pump.
Petrochemical industry is the blood of national economy. RSP participates in the system industry of petrochemical industry with screw pump products that meet advanced standards. In the upstream mining stage of large equipment lubrication, crude oil transportation, sewage treatment system, the upstream storage and transportation stage of cargo oil loading and unloading, pressurization system, downstream smelting stage of industrial processes, oil handling, sewage treatment system, RSP continues to provide oil industry customers with ideal pumping solutions.
At present, RSP has established long-term and stable cooperative relations with large petroleum companies such as PetroChina and Sinopec, and has actively cooperated with some internationally renowned oil mainframe equipment manufacturers to participate in the design of their major projects, including Atlas Copco, Burckhardt Compression and so on.

Ensure that the impurities do not enter the pump body, the solid impurities mixed in the wet sludge will cause damage to the rubber stator of the screw pump, so it is very important to ensure that the impurities do not enter the pump chamber. Many sewage plants install crushers before the pump, and some install grille devices or filters to prevent impurities from entering the screw pump, so the grille should be removed in time to avoid blockage.
To maintain a constant outlet pressure, screw pump is a kind of volumetric rotary pump. When the outlet is blocked, the pressure will gradually increase, so that it exceeds the predetermined pressure value. At this time, the motor load increases sharply. The load of the related parts of transmission machinery will also exceed the design value. In serious cases, the motor will be burnt down and the transmission parts will be broken. In order to avoid screw pump damage, bypass relief valves are usually installed at the outlet of the triple screw pump to stabilize the outlet pressure and maintain the normal operation of the pump.
