Haina centrifugal pump inspection and acceptance methods

Haina centrifugal pump inspection and acceptance methods Hetan pump inspection methods: Haina centrifugal pump equipment shipped to the site, the supervision of the organization of the relevant personnel on the equipment according to the equipment arrival list for inspection, inspection equipment specifications, quantity and quality and various Technical documents and information. For a factory acceptance certificate, packaging integrity, visual inspection found no abnormalities, transport custody in line with technical requirements, may not be disintegrated. If the quality of the production of doubt or due to improper storage and other reasons affect the quality of equipment, they should be disintegrated. To ensure the quality of the installation, the main dimensions related to the assembly and the tolerances should be checked, including the following. 1, Haydn multistage centrifugal pump and motor combination of the joint inspection should meet the following requirements. (1) Check the gap with a 0.05mm feeler gauge and the feeler gauge can not pass through the gap. (2) When a partial clearance is allowed, check with a feeler gauge not more than 0.10mm in depth not to exceed 1/3 of the width of the combined surface and not to exceed 20% of the total circumference. (3) Combination of joints at the installation surface height should not exceed 0.10mm. 2, impeller roundness, height, center, seal leakage, blade adjustment structure. 3, the length of the pump shaft, only the mouth, journal and bearing with the gap. 4, impeller and shell gap. 5, the top of the tubing and regulator copper sleeve with the size. 6, motor rotor shaft length, pole roundness, stator diameter. 7, Thrust head and motor shaft with the gap and the key to connect with the keyway. 8, snap ring and snap ring groove with the gap and the key to connect with the keyway. 9, snap ring and snap ring groove with the gap and mirror inspection. After inspection and acceptance, according to their purpose, structure, weight, size and use of successively, combined with on-site conditions to determine the place of custody and storage. Centrifugal pump related products: SFB stainless steel corrosion-resistant centrifugal pumps, ISG vertical pipe centrifugal pump, ISW horizontal pipe centrifugal pump.
