Pump troubleshooting eleven tips

【Start pump does not turn】

-------------------------------------------------- ------------------------------
Reason: packing is too tight or clogged with debris between the impeller and the pump body; pump shaft, bearings , leak ring rust live; serious axis pump.
Remedy: Loose packing, clear the diversion channel: open the pump body to remove debris or rust; to correct the curved shaft or a new pump shaft.

【Start pump does not water】

-------------------------------------------------- ------------------------------
Reason: pump air or gas intake manifold; the bottom valve is not strict irrigation water is not satisfied, a serious vacuum pump packing leaks; gate valve or beat the door closed lax.
Remedy: remove debris, replace the damaged rubber mat, change the direction of the valve; press or replace the new packing, close the gate valve or the door; increase the amount of irrigation until the deflation plug does not bubble; replace with Cracked tube water; reduce head, the pump nozzle pressed into the water 0.5 meters.

【Insufficient traffic】

-------------------------------------------------- ------------------------------
Reason: The actual head of the pump exceeds the allowable head; speed does not match or belt slippage, low speed; axial pump blade mounting angle is too small; suction stroke is too high; end valve, pipe and impeller partial plug or impeller defect; serious.
Remedy: Reduce the lift, restore the rated speed, remove the belt dirt and adjust the belt tightness; adjust the blade angle, reduce the pump installation position; tighten the gland, seal the pump leakage, compression packing or replacement packing; clear the blockage, Replace the impeller; replace the leak ring, plug the leak.

Flow from smaller to smaller

-------------------------------------------------- ------------------------------
Reason: the filter or the bell is gradually blocked by debris; dynamic water level decreases, the water inlet submerged depth of water is not enough.
Remedy: Remove debris, increase the depth of the bottom valve into the water.

【Outlet interruption in operation】

-------------------------------------------------- ------------------------------
No water or intermittent broken water, less water.
â‘  motor is not started, eliminate circuit failure;
â‘¡ pipeline blockage, remove blockage;
â‘¢ pipeline rupture, repair welding or for praise;
â‘£ filter plugged, remove clogs;
⑤ water inlet exposed water, if the next discharge pump is still invalid, it is recommended to change the pump;
â‘¥ electric pump reversal, replace the power line phase sequence;
⑦ pump housing seal ring, impeller damage, replacement of new parts.

【Motor can not be started, accompanied by hum】

-------------------------------------------------- ------------------------------
â‘  If one phase opens, repair the line;
â‘¡ bearing axle, repair or replacement;
â‘¢ impeller with foreign body and pump stuck, remove foreign body;
â‘£ low voltage, adjust the voltage.

【Current is too large, ammeter pointer swinging】

-------------------------------------------------- ------------------------------
â‘  rotor sweep chamber, replace the guide bearing;
â‘¡ shaft and bearing relative rotation is not flexible, replacement or repair bearings;
â‘¢ due to severe thrust bearing wear, leaf rotation and seal ring phase, replace the thrust bearing or thrust plate;
â‘£ axis bending, bearing different heart, to send crampons plant repair.

【Insulation resistance of motor winding to ground low】

-------------------------------------------------- ------------------------------
Motor windings and cable connectors or cables are damaged, replace windings, repair connectors or cables.

【Vibration of the unit during operation】

-------------------------------------------------- ------------------------------
â‘  motor rotor imbalance, in addition to loose bolts can be fastened, the rest of the fault sent to the manufacturer;
â‘¡ pump impeller imbalance;
â‘¢ motor or pump shaft bending.

Loose connection bolt

-------------------------------------------------- ------------------------------
Cause: There is blockage of debris in the pipeline or water inlet. The packing is worn and loose, the blockage of the water seal tube. The impeller is broken or loosened.
Remedy: remove clogs, replace the filler, clear the guide pipe groove, correct installation of water seal; fasten or replace the impeller; reduce the pump installation location, or until the water level rise and then boot.

【Power consumption is too large】

-------------------------------------------------- ------------------------------
Reason: high speed; pump shaft bending; leaves around a debris; head is too high.
Remedy: Adjust the appropriate speed; correct pump shaft.

Steel Stamping Parts

Stamping is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene.

Stamping is usually done on cold metal sheet. See Forging for hot metal forming operations.

Equipment for stamping: Stamping machines, Hydraulic press machines, Auto-Turning machines, CNC-Turning machines, Milling machines, Precision wire cutting machines, more than 160 sets in total.

Steel Stamping Parts are very popular in forging process. We can supply big range of such steel stamping parts.
