Product Overview
Three-screw pump is a positive displacement pump, and has the remarkable advantages such as simple structure, small volume, being allowed to rotate at high speed, stability and reliability, small pressure pulsation, stable flow rate, low noise, high efficiency, etc.. By using the principle of screw meshing and relying on the mutual meshing of rotating screws in pump block, the three-screw pump sucks the medium conveyed and seals it in the meshing cavity, then pushes it to the discharge port along the axial direction of screws at uniform speed, and forms stable pressure at the discharge port.
Three-screw pump is only applicable to conveying lubricating fluids not containing solid particles at normal temperature. It may be used as a common delivery pump, and a pressure supply pump in hydraulic drive device. The 3QGB series heat-preservation high-viscosity three-screw pumps developed by the Company after many years of research optimize the cooperation between screws and pump block, and between driving screw and driven screw based on three-screw pump, in order to realize the delivery of high-temperature and high-viscosity media.
The 3QGB series heat-preservation high-viscosity three-screw pumps are mainly used to convey high-viscosity lubricating fluids. They are usually used as the delivery pumps of asphalt, heavy fuel oil, heavy gear oil, and heavy diesel fuel. Inside the pumps, heat preservation chamber and channel are set up, gas or liquid could be used as heat-carrier, and their maximum working temperature is equal to or lower than 350℃. High-viscosity media are generally conveyed after cooling down and viscosity reduction, and the conveying viscosity is generally 3.0~760mm²/s.
The Company’s 3QGB series heat-preservation high-viscosity three-screw pumps include various models with inlet and outlet diameter of from DN40 to DN300 and flow rate of from 2.8m³/h to 300 m³/h, and could meet different customers’ demands.
