RY-type air-cooled heat pump installation quality is related to the life of the pump, then install the pump, you need to pay attention to what matters? With this question, the following is about RY-type air-cooled Hot oil pump installation notes introduced. RY-type air-cooled heat pump installation precautions 1. Air-cooled heat transfer oil pump installed before installation should check the oil seal is good, and check whether the damage in transit, the hand rotation of the coupling if there is Karman phenomenon. 2. If the air-cooled heat pump is a single machine and the motor pump, the pump head keys and keyway should be stabbed, repaired, pouring machine oil, and then install the pump shaft pump shaft, Machine seal rupture. 3. Install the pump suction and discharge pipelines, the diameter of not less than the suction pump and oil drain port diameter, suction pipe must not be too long, elbow not too much, otherwise it will affect the pump's working condition. 4. All pipelines, gate valves, valves, etc. should be rinsed clean before installation, otherwise the residues in the installation: such as welding slag, steel balls, nuts, screws, etc. will damage the internal parts of the pump and affect the pump operation Therefore, the filter should be installed on the suction pipe. The size of the mesh of the filter can be determined according to the working conditions and the viscosity of the medium. Generally 40 to 80 meshes are available. The filtration area should not be less than 20 times of the oil absorption cross-sectional area. For the poor transmission medium clean residue or heavy oil, the best three-tier filter, the filter should be cleaned regularly, in order to ensure adequate supply of oil. 5 hot oil pump foot must be placed on the foundation smooth, ground screw must be tightened. 6. The coupling of coaxiality, straightness must be used steel ruler, feeler to check from four directions. 7. After assembly should be able to easily rotate the main hand. 8. The suction and discharge lines must be properly connected to the pump body flange. Never screw the pump body with the suction and discharge lines in place, and do not forget to place shims or "O" rings. 9. If possible, the nominal size of the suction and discharge pipes of the pump shall be such that the flow velocity of the suction pipe is not more than 1m / s and the flow velocity of the discharge pipe is not more than 3m / s. 10. When two or more pumps are installed on the same main line, In order to facilitate pump pressure start, near the pump drain pipe must be installed check valve. 11. Connect the vacuum gauge and pressure gauge to the threaded holes in the suction and discharge ports of the pump to observe the operating status of the pump.
