The working principle of one and three screw pumps
The screw pump transports liquid by virtue of the change in volume of the screw intermeshing space. When the screw rotates, the sealing line at one end of the suction chamber continuously moves axially to one end of the discharge chamber, so that the volume of the suction chamber increases, the pressure decreases, and the liquid enters the suction chamber along the suction pipe under pressure differential action. With the rotation of the screw, the liquid in the sealing chamber is continuously and uniformly moved in the axial direction to the discharge chamber, and the liquid is discharged as the volume of one end of the discharge chamber is gradually reduced.
The screw pump is a positive displacement pump and its pressure is determined by the total resistance of the piping system to which it is connected.
Second, the characteristics of the screw pump:
1 excellent self-priming performance.
2 The flow rate is almost zero.
3 simple and compact structure.
4 Extremely simple maintenance requirements.
5 Let your satisfaction service life.
6 The conveying medium is free from foam and eddy currents.
Third, the type of transmission medium:
1. Lubricity liquids, such as mechanical oils, spindle oils, transformer oils, heavy oils, and residual oils;
2. Low-lubricity liquids, such as wax oil, light diesel oil, heavy diesel oil, high temperature asphalt, coal Tar, etc.
3, viscous liquids, such as grease, viscose, asphalt, etc.
Four and three screw pump selection instructions
Although the three-screw pump has many advantages, if it is improperly selected, it will not only not achieve satisfactory operation results, but will also cause noise and vibration of the pump, and even seriously damage the internal parts of the pump, making the pump system unable to work properly. Selection personnel should consider carefully and rationally select models. If necessary, consult the technical department of our factory.
When selecting a three-screw pump, it is necessary to understand the operating conditions of the pump as thoroughly as possible. In addition to the operating parameters such as the flow rate and the pressure need to be clearly defined, the characteristics of the medium to be transported such as the corrosiveness of the medium, the amount of steam, and the ratio of the solid solution. And the size of the solid particles, as well as the working temperature, viscosity, specific gravity of the medium, corrosivity of the material, suction conditions of the pump device, and installation conditions are all to be understood. According to our experience, the following should be noted when selecting the triple screw pump. Points:
1. Select the pump speed
to determine the speed range with the viscosity of the pump and the pump's specifications:
1.1 When pumping high-viscosity media, the pump should be selected for low speed. If the viscosity is low, the corresponding high speed can be selected:
medium viscosity > 150cst. For large size pumps (outer diameter 60mm or more), the rotation speed is 970rpm or 720rpm. If the viscosity is higher (viscosity) 600cst), for example, viscose liquid, it can reduce the speed. 200-500rpm is recommended;
for small size Pump, medium viscosity> 150cst, rotation speed to 1450rpm or 970rpm is appropriate, if the viscosity is higher (viscosity) 600cst), can reduce the use of speed, recommended 300-600rpm;
1.2 The higher the pump speed, the smaller the pump's volume under the same performance parameters. However, due to the high speed and high friction power, the pump wear is large and the service life is short. If the transmission medium has poor lubricity or contains For trace impurities, lower speeds should be selected so that the pump maintains a longer life, recommended below 1450 rpm.
2. The structure can be selected according to the installation and use conditions of the pump with reference to the series and type of the three-screw pump. In principle:
2.1 Lubricant oils are transported, and the pump with the built-in bearing structure is selected below 80°C;
2.2 The temperature is exceeded When the lubricity of the medium is poor at 80°C or when the medium is poor, the pump with external bearing structure is selected.
2.3 The pump with poor fluidity and high viscosity, or the pump with the double-layer heat pump structure when the medium to be heated or heat-retained is required;
2.4 High temperature When transporting, pumps made of high temperature resistant materials should be selected. Please contact our factory.
3. Selection of pump material combinations:
Different media types are required to deliver different combinations of materials.
1. The three-screw pump is divided into body and body sets and body sets.
The material combination of the body-in-one pump is as follows:

Low pressure fluids with good viscosity, such as heavy fuel oils, can be delivered at low pressure.
At higher pressures, poorly lubricated liquids with lower viscosity, such as heavy oil and fuel oil, are delivered.
It can deliver low viscosity and poor lubricity media such as diesel fuel and light fuel oil.
It can deliver low lubricity liquids with suitable viscosity.
Low-viscosity liquids with poor viscosity, such as crude oil and fuel oil, can be delivered at low pressure.

For special occasions (such as water pump), the medium with good viscosity and good viscosity is conveyed under higher pressure. Poorly lubricating medium such as heavy oil, fuel oil, light diesel oil, etc. can also be delivered under slightly lower pressure.

4. Refer to the sample supplied NPSHR for pump suction capacity.
5.
After selecting the matching pump for the matching motor, the shaft power N of the pump can be found according to the sample data. After the shaft power plus a certain power reserve, the motor power Nm should be used as the basis for selecting the matching motor. Not less than the value obtained by multiplying the power of the pump shaft N by the power reserve coefficient K, the K value can be referenced

Generally, the following principles can be used to make a rough estimate. If more accurate data are required, consult a professional.
· The flow rate and pressure of the three-screw pump are approximately linear in the same rotation speed and viscosity. The higher the pressure, the smaller the flow rate.
· With the same viscosity and pressure, the pump flow rate is approximately proportional to the speed.
At the same speed and viscosity, the shaft power is approximately proportional to the pressure.
· Under the same viscosity and pressure, the shaft power is approximately proportional to the speed.
· When the viscosity increases, the flow rate and shaft power increase, but due to the more complex relationship, consult a professional when necessary.
As long as the type is properly selected and the maintenance is reasonable, the triple screw pump can achieve satisfactory operation.
