RY air-cooled high-temperature heat pump installation
RY air-cooled high-temperature heat-conducting oil pump unit installation and use: 1, the pump installation is good or bad pump smooth operation and service life has a very important impact, so the installation must be carefully carried out, not sloppy. 2, pump suction pipe installation height, length and diameter should meet the calculated value, and strive to short, reduce unnecessary losses (such as elbows, etc.). 3, suction and discharge pipe should be pipe rack, the pump is not allowed to withstand the load of the pipeline. 4, the installation site should be wide enough to facilitate the maintenance work and good heat dissipation. 5, the installation sequence: (1) the unit on the foundation of the buried anchor bolts, put a pair of pads between the base and the foundation, to find positive use. (2) Loosen the coupling and place the level gauge on the pump shaft and the base separately. Adjust the wedge pad to make the unit horizontal. After adjusting, properly tighten the anchor bolt to avoid walking. (3) Concrete pouring base and anchor bolt hole. (4) After the concrete is dry-solid, check whether there is any defect or looseness of the base and anchor bolts. Tighten the anchor bolts after the inspection and check the level of the pump again. (5) To adjust the concentricity between the pump shaft and the motor shaft, the deviation on the outer circle of the coupling allows 0.1 mm. The clearance between the two coupling planes should be 2 to 3 mm. , The maximum and minimum gap difference shall not exceed 0.3 mm. (6) After connecting the pipeline and determining the direction of prime mover rotation, connect the coupling again and check the concentricity of the circle again. (7) After the actual commissioning of the unit for 3 to 4 hours for the final inspection, if there is no adverse phenomena that the installation of qualified. (8) During the installation to prevent debris falling into the machine, all the holes should be covered unit. (9) Before the pump clears the inlet and outlet lines before the pump is turned on, a filter must be added to the inlet section of the pump to prevent debris from entering the pump.
