3QGB screw pump is a positive displacement pump with the advantages of simple structure, small volume, stable and reliable high-speed operation, low pressure pulsation, stable flow rate, and low noise. It is mainly suitable for transporting various non corrosive oils and liquids similar to oils, with a viscosity range of 3.0-760mm2/s (1.2-1000oE) for the transported liquids. High viscosity media can be transported by heating to reduce viscosity, and their temperature generally does not exceed 350 ℃. The 3QGB screw pump is made of cast steel and comes in two types: insulated and non insulated. It is recommended to use insulated screw pumps for high viscosity media. twelve
The spiral sealing wire in contact between the stator and rotor of the pump completely separates the inlet chamber from the outlet chamber, giving the pump a valve blocking effect. It can achieve multiphase mixed transportation of liquid, gas, and solid. When the fluid flows inside the pump, the volume does not change, and there is no turbulence or pulsation caused by turbulent flow. The volume cavity formed by the elastic stator can effectively reduce the wear during the transportation of media containing solid particles. The viscosity of the input medium can reach 50000 Mpa · s, and the solid content can reach 50%. The flow rate is proportional to the speed, and automatic adjustment of the quantity can be achieved with the help of a speed regulator.
The 3QGB screw pump has a wide range of applications, including being used as a fuel injection pump, fuel supply and delivery pump in heating equipment; Used in the mechanical industry as hydraulic, lubrication, and remote control motor pumps; Used as loading, conveying, and liquid supply pumps in chemical, petrochemical, and food industries; Used on ships for conveying, boosting, fuel injection, lubrication oil pumps, as well as ship hydraulic device pumps.
In addition, the technical parameters of the 3QGB screw pump include a flow range of 0.2-600m3/h and a working pressure of up to 6.3MPa. The pump has good sealing performance and adopts mechanical seals. Different materials are selected for the friction parts of the mechanical seal according to the user's different media. For high viscosity media, hard alloy materials with high mechanical strength and good wear resistance are selected to ensure sealing performance at high temperatures.
