Stainless steel self-priming pump troubleshooting
Stainless steel self-priming pump motor part [Symptom] 1, no response after turning on the power. 2, difficult to start or can not start, and accompanied by "buzzing" sound. 3, the motor can run, but the speed is slow, and the chassis overheating, burnt smell. 4, running noise, vibration. [Remedy] 1, most of the power plug, power leads and motor windings due to short circuit. 2, overhaul small bamboo can be used to quickly move the direction according to the operating fan, if the motor is running quickly, indicating that the start capacitor or winding damage, should replace the same capacity capacitor or repair winding; if the motor card, mostly motor and Pump head mechanical failure, such as bearing damage, impeller stuck. 3, most of the motor windings caused by short circuit, the motor should be opened, depending on the damage were welding, jumper, isolation, rewinding and other measures to repair. 4, the majority of bearing damage or improper bearing with the chassis, the need to open the motor check, if the bearing damage should be replaced; if the bearing run outside the circle, the casing can be used with the handle face 錾 flower treatment; if the bearing run inside the circle , Wear parts of the motor shaft can be used Kui Hua treatment, serious wear and tear, the use of the first method of surfacing surfacing repair. Stainless steel self-priming pump head part ã€Symptom】 1, the normal operation of the motor but the water is less or no water. 2, the shell charged. [Remedy] 1, this situation should first check the pump seal, check the power plug should be unplugged, hand plugging the suction port, the pump filled with water, stuck in the mouth outlet forced inward blow, observe Pump head is leaking, where the leak is the seal damage. Common parts of the faulty suction pad, outlet mat, impeller pad, maintenance should be replaced. If there is no full water phenomenon, mostly impeller damage, between the water chamber and the water chamber between the water within the septum wear, pump head water separated by grinding flat, the impeller and the pump housing to increase the gap should be replaced impeller and pump housing . Replace the impeller should pay attention to the complete removal of the remaining copper pump blades, so as not to damage the new impeller again. 2, the majority of water seal damage, water penetration into the motor shaft through the motor so that the deterioration of motor insulation performance can be replaced by water seal, drying motor and other methods of repair. It should be noted that, because the pump long-term contact with water and open-air work, easily damp caused insulation performance deterioration, in order to ensure personal safety, electric stainless steel self-priming pump should be grounded.
Nano is an innovative technology that can deposit very fine and thin metal films on products. Applied to stainless steel sinks, this technology ensures the durability and longevity of the product's color and helps maintain its beauty. Nano-coating makes the sink antibacterial, waterproof and oil resistant.
