Any equipment has a service life. The length of service life is not only related to the quality and performance of the equipment itself, but also related to people's use specifications. If we do not use the equipment according to the conventional requirements, the service life of the equipment will be shortened. Today, Xiaobian will introduce you to the three taboos of submersible pump. I hope all readers in front of the screen can cheer up and have a good understanding of this content.Do not rotate in the opposite directionSubmersible pumps are divided into single-stage pumps and multi-stage pumps. According to common sense, the single-stage pump with lower head and the multi-stage pump with higher head. In the process of using single-stage pump, it is recommended to distinguish the direction. Although the submersible pump can discharge water whether it is positive or negative, it is recommended that you turn forward rather than reverse. In case of reverse rotation, the motor winding may be damaged. And to be honest, when the single-stage pump of submersible pump is in the reverse state, the water output is still relatively small, so it is better to turn forward. In addition, a warm reminder. I hope you can check carefully before pumping the single-stage submersible pump into the water to see if the rotation direction of the single-stage submersible pump is abnormal. If it is abnormal, it should be adjusted in time. After it is normal, it can be put into the water.Do not overload operationWhether it is people or equipment, as long as they work overload, it will cause certain damage to themselves, and so will the stainless steel submersible pump. Xiaobian told you above that the head of single-stage submersible pump is generally small, so for those work fields that need high head submersible pump, single-stage submersible pump can not be used. If you have to use a single-stage submersible pump, you should pay attention to it in the process of use, so as to prevent the current value from exceeding the normal range and burning the equipment.High frequency startYou know what? When the single-stage pump of the submersible pump is closed, the submersible pump will produce backflow. At this time, if you press the start button to make the submersible pump work, it may cause damage to the motor and make the motor load start. After the motor load starts, the starting current will become large. To a certain extent, it will inevitably cause various problems in the equipment. At the same time, shorten the service life of the equipment. Therefore, when using submersible pumps, we must not make taboos in this regard. According to common sense, if you want to start the submersible pump and single-stage pump again, it should be at least five minutes apart.
