Acceptance method of self-priming sewage pump
The inspection standards for self-priming sewage pumps are mainly introduced in detail:
1. Parts of self-priming sewage pump.
2. The working function of the self-priming sewage pump.
3. Technical data of self-priming sewage pump.
4. Equipment and environment.
1. Parts of the self-priming sewage pump: the body and all parts and components of the self-priming sewage pump are complete and complete. The connection bolts of all parts are thorough, the connection is tight, and there is no rust. Complete and stable safety protection equipment. Pressure gauges, ammeters and other surfaces are thorough and flexible, and the ranges meet the regulations and are regularly calibrated. The inlet and outlet valves and the lubrication and cooling system pipelines are neatly installed, with obvious signs, and the oil standard and oil cup are completely easy to use. The cooperation of all devices is in compliance with the regulations. The self-priming sewage pump body, pump seat and auxiliary pipelines and fittings are completely painted. The foundation and base are complete and solid.
2. The working function of the self-priming sewage pump: the oil circuit is dredged, the lubrication is good, and the "five set" and "three-stage filtration" are implemented. The operation is stable, and there are no abnormal phenomena such as abnormal vibration and noise. The pressure and flow are stable, the temperature of each part is normal, and the current is stable. The capacity can reach the nameplate output or verification capacity.
3. Technical data of self-priming sewage pump. There is a certificate of quality for the product quality certificate with the instruction manual. The self-priming sewage pump produced by our company has guaranteed quality, perfect after-sales service and obvious price advantage! The operation procedures and maintenance and repair procedures are thorough. There are general assembly drawings or structural drawings of the self-priming sewage pump, and drawings of vulnerable parts. The equipment file is complete and the data is accurate, including: installation and commissioning inspection data; equipment operation records; previous maintenance and inspection records; equipment defects and accident status records.
4. Equipment and environment. There is no leakage at the inlet and outlet valves, flange interfaces and joints of each section of the pump body. The equipment is clean, and the surface is free of dust, dust and grease. The foundation is clean, the surface is free of stagnant water and debris, and the environment is neat and clean. The leakage at the shaft seal should not be greater than: packing seal, no more than 20 drops per minute in the initial stage, no more than 40 drops per minute in the late stage; mechanical seal, there should be no leakage in the initial stage, and no more than 5 drops per minute in the late stage.
