Selection and configuration of the screw pump and the use of the boot note

1. Is strictly prohibited without the medium idle, please be sure to start before driving into lubricating medium or medium.

2. All the debris into the pump cavity is prohibited, be sure to keep the pump cavity and the cleanliness of the inside of the pipe.

3. Prohibited the use of pipe filter or Y filter device, filter, please ensure that the filter area is 20-40 times the size of the pump inlet. According to the cleanness of the filter medium the correct configuration of the mesh.

4. Is strictly prohibited import and export of the pump pipe and pump does not match the import and export pipeline, pipe diameter configuration must be consistent with the import and export of the pump. In order to avoid the occurrence of cavitation or can not self absorption. Meticulous pipeline is bound to lead to cavitation, so that the pump work in hungry condition, leading to the three screw pump flow pressure decline or even abnormal vibration and noise, long operation time will also lead to serious damage to the pump and screw pump card

5. Three screw pump installation height must be fully considered pump cavitation conditions and the pump's self absorption capacity (cavitation margin and the viscosity of the medium and the screw guide)

6. Due to packaging lifting transportation loading and unloading and pipe fastening bolt effect may be easy to pump the original factory location change even serious dislocation, so three screw pump group tube system configuration fixed end, must be in start the car before the re examination of the three screw pump and motor coaxial degree.

7. Is strictly prohibited back pressure to start the boot and close the case of the import export valve boot boot.

8. Is strictly prohibited does not meet the direction of rotation of the pump to start rotating.

9. The two pumps must be in parallel in the export and import plus one-way valve to prevent the media back to drive the three screw pump.
