What are the precautions for installing a thermal oil pump?
The installation of the heat transfer oil pump has a significant impact on the smooth operation and service life of the pump, so the installation work needs to be carried out carefully and should not be done hastily.
The installation height, length, and diameter of the suction pipe of the heat transfer oil pump should meet the calculated values, striving for simplicity and reducing unnecessary losses (such as bends).
3. The suction and discharge pipelines of the heat transfer oil pump should have pipe racks, and the pump is not allowed to bear the load of the pipeline.
4. The installation location of the heat transfer oil pump should be wide enough to facilitate maintenance work and good heat dissipation.
5. Installation sequence:
1) Place the unit on a foundation with embedded anchor bolts, and place a pair of pads between the base and the foundation for reference.
2) Loosen the coupling and place a spirit level on the pump shaft and base respectively. Adjust the wedge pad to make the unit level. After aligning, tighten the anchor bolts appropriately to prevent movement.
3) Pour concrete into the base and anchor bolt holes.
4) After the concrete has dried and solidified, check the base and anchor bolts for any defects or looseness. After passing the inspection, tighten the anchor bolts and recheck the levelness of the pump.
5) Correct the coaxiality of the pump shaft and motor shaft. The deviation on the outer circle of the coupling is allowed to be 0.1 millimeters, and the gap between the two coupling planes should be protected by 2-3 millimeters. The difference between the larger and smaller gaps around the end faces of the two couplings should not exceed 0.3 millimeters.
6) After connecting the pipeline and determining the direction of rotation of the prime mover, connect the coupling again and verify the coaxiality of the coupling.
7) After 3-4 hours of actual trial operation of the unit, conduct a post installation inspection. If there are no defects, the installation is considered qualified.
8) To prevent debris from falling into the machine during installation, all holes in the unit should be covered.
When cleaning the inlet and outlet pipelines before starting the pump, a filter should be added to the inlet section of the pump to prevent debris from entering the pump.
