the right way to buy pumps

there are a lot of manufacturers on the market main problems of the quality of the water water pump is a grounding device, grounding line and logo and electric pump efficiency, flow, lift, unqualified product nameplate, etc. Grounding device, grounding line and the logo is an important indicator of pumps electrical safety performance, no grounding device or online logo is not clear, fixed, can bring potential safety hazard to consumers. Electric pump efficiency, capacity and head on the low side, directly affect the overall performance of the unit. Unqualified product nameplate sign not express product main performance, no guidance for users to buy the product even mislead consumers.

Nameplates shall be fixed at the site of the pump is obvious, and indicate the factory name, address, name and model number of submersible pump, flow, head, pipe diameter, rated power, rated frequency, rated voltage, current and synchronous speed, the number of phase, the insulation class, factory number or production date, electric pump weight, product standard number, product license number, etc. There should be marked on the electric pump. If the project should be no label or mark on product label is not complete, the pump should not buy. 4. Check to see if the factory has obtained the production license.

According to the head choose submersible pump. According to the height of the water level above the ground to determine and choose the submersible pump head. The standard provisions of the state, the use of submersible water pump safety head should be between the head of 83% ~ 140%. For example, specifications for QS25 - 24/2 - 3 a fountain of submersible pump, its flow is 25 cubic meters per hour, head of 24 meters, the water level high from the ground in 24 & times; （ 83% ~ 140%) 19. 9 ~ 33. 6 m range is relatively appropriate. 6. Carefully check grounding mark and ground wire. Stainless steel submersible pump should be reliable grounding device and ground wire, it raises cable grounding line should have obvious signs, grounding line should be yellow green double color line, and ensure the mark in the using period, indelible. 7. Check which leads to the cable. Large submersible pump cable should be used in derivation of the medium-sized rubber sets of cables, select cable length is close to the lift pump, when used to prevent leakage caused by careless wiring. 8. Check whether there is certificate and operation instruction. 9. Test run to see if normal. Connected to the power supply should be running freely, smooth, without the phenomenon such as binding, no scratches.
