7.4.2 During factory inspection, the various indicators of the pump shall comply with the provisions of Articles 5.5, 5.6 and 5.11. If all the indicators of the pump meet the above provisions, it is a qualified product. If one of the indicators in the above provisions is not met, it is a non-conforming product. 8
Marking, packaging and storage
The nameplate of the pump should be fixed on a conspicuous part of the pump, and the size and technical requirements of the nameplate should comply with the provisions of GB/T13306. The nameplate should include the following contents:
Manufacturer name;
Pump model and name;
Main technical specifications: rated flow, m/h; rated discharge pressure, MPa; rated boost pressure, MPa; pump speed, min-1: prime mover c.
Power, kW; weight, kg;
Factory number;
Year and month of production.
The pump should be marked with the registered trademark.
Important externally purchased supporting equipment of the pump should also have a nameplate. The transmission housing of the pump should have an indication of the direction of rotation of the crankshaft. Other important equipment that is only allowed to rotate in one direction should have an indication of the direction of rotation. The pump should be treated with rust prevention or paint. All passages to the atmosphere should be sealed. Flanges and welding grooves should be covered, and auxiliary pipelines with smaller diameters should be removed or temporarily supported.
8.6 The accompanying documents of the pump should include installation drawings, drawings of wearing parts, product instructions, packing lists, and product certificates. The documents should be wrapped in watertight plastic bags and placed in packaging boxes.
JB/T6538-92
The packaging of the pump should comply with the provisions of GB/T13384 and should be closed. 8.7
Under normal storage conditions, the manufacturer should ensure that the pump will not rust within six months from the date of shipment. Metering device
