The use of stainless steel submersible pumps cannot be separated from the maintenance and upkeep of the equipment by the staff, but many customers often overlook this, resulting in common machine malfunctions that often occur and ultimately lead to small losses. In order to make the use of stainless steel submersible pumps smoother for everyone in the future, it is necessary to check the cables, power switches, electric shock protectors, etc. before using them. Household appliances such as power switches should be running normally, and the cables should be undamaged. At the same time, it is important to carefully identify the cables, as the yellow and green dual color wires are wire connectors, to avoid electrical accidents.
Every once in a while, check the grounding resistance of the submersible pump before use, which should not be less than 0.5M Ω. If it does not meet the requirements, it needs to be dried. Regularly maintain the water inlet and oil inlet, and tighten them if no abnormalities are found.
After 300 hours of operation, the stainless steel submersible pump needs to be checked for water addition. If the discharged or oil-water mixture is less than 25mL, it can continue to be used. Otherwise, the hood and silicone seal ring need to be checked for damage.
Due to the fact that stainless steel submersible pumps are usually used underwater, if they need to be debugged outside the water, they should not exceed 5 minutes to avoid the motor overheating and burning out. Carrying out maintenance and upkeep on stainless steel submersible pumps can not only ensure the operation of the machinery and equipment, but also increase the service life of the machines and reduce the operating costs of the enterprise. Why not do it.
Various models and specifications of submersible pumps require regular inspection and maintenance of the submersible pump and automatic control system, which must be done annually Secondary protective maintenance, basic content: whether there are any abnormal vibrations, sounds, current and voltage after starting up, whether there are any problems with the starter during operation, whether there is an alarm for overheating and water leakage, whether the maintenance of the control system is frequent, whether the main cable and variable frequency cable are aging and cracked, whether the main contactor is stuck to air oxidation or burrs, whether the thermal relay is set correctly, whether there are signs of aging in the winding insulation layer, whether the ground insulation resistance is too low, whether the three-phase winding resistance value is balanced, whether there are cylinder jamming or scratches in the stator and rotor, whether the automatic control system liquid level transmitter is accurate, whether the upper and lower limit exports are reliable, whether the float switch posture is reliable, whether the environmental temperature detection components are aging and malfunctioning, Is there any emulsion in the oil product, and is the machine seal intact Whether the rolling bearings are damaged, whether the centrifugal impeller is damaged or corroded, whether the shaft is corroded, deformed or damaged, whether the fastening screws inside and outside the motor are loose, whether there are dirt in the refrigeration jacket and circulating water pipe, etc.
