 1. Overview of three screw pumps:
 The three-screw pump is a rotor-type positive displacement pump. It uses the principle of screw meshing and relies on rotating screws to mesh with each other in the pump sleeve to transport the medium.
 Enclosed in the meshing chamber, it is continuously pushed to the discharge port at a uniform speed along the axial direction of the screw to provide a stable pressure for the system. 
 It is suitable for all kinds of non-corrosive oils and similar oils and lubricating liquids. The viscosity range of the conveying liquid is generally 3.0-760mm2/s (1.2-100oE), and the high-viscosity medium can be transported after heating and viscosity reduction. Its temperature does not exceed 350℃. 
   The LQ3G thermal insulation screw pump (thermal insulation type asphalt pump) produced by our company is mainly used to transport high-viscosity and high-temperature lubricating liquids. It is commonly used in the transportation of media such as asphalt, heavy fuel oil, and heavy gear oil. The heat carrier can be steam, hot oil and hot water, and the cold carrier can be gas and liquid. 
 
the characteristics of thermal insulation screw pump:
 The distinctive features are simple structure, low pressure pulsation, stable flow, reliable working balance, high allowable speed, low noise and high efficiency.、
 Long life span and self-priming ability.

Brief technical data:
  • Capacity: 4.5m3 /h ~ 252m3 /h
  • Head: 60m ~ 250m
  • Viscosity: 3.0 ~ 760 mm2 /s
  • Medium temperature:
Screw LQ3G Three screws The pumps are used for pumps of various substances with a temperature of 350 degrees Celsius and a high viscosity of 30-760 mm2 /s.
LQ3G type horizontal Pump 3 screws
Wide use:
  • Pump fuel oil, crude oil, heavy oil, asphalt, rubber, resin, such various kinds of oil fluid lubrication in petroleum industries
  • Chemical fiber, metallurgy, road construction, electricity, mining, shipbuilding, glass, etc.
  • The cast double jacket allows the heat storage fluid to pass through to maintain or cool the heat of the pumped medium.
