Submersible pump is a very professional product, non-professional understanding of its very little. Submarine pump how safe and reliable use is the majority of users are very concerned about, but also troubled users of an important issue. Below the submersible pump suppliers!
1, submersible pump power must be grounded and reliable, the installation of leakage protection;
2, the outlet pipe as much as possible not to bend, timely detection and repair of the rupture of the water pipe to reduce power loss;
3, the debris more water pumping when adding filter;
4, before and after the correction of positive and negative power supply, so as not to reverse the pump, no water;
5, the use of submersible pumps found abnormal circumstances, the timely cut off the power to identify the situation after the resumption of work to continue.
According to the relative position of the pump and the motor is different from the submersible pump can be divided into the pump and the next pump. On the pump submersible pump pump on the top, the motor in the following, this structure greatly reduces the radial size of the pump, so it is used for submersible pumps and small operation submersible pumps. Under the pump submersible pump motor in the above, the pump below, it is divided into both built-in and exterior type. The liquid pumped by the pump submersible pump is first passed through the annular flow path that surrounds the motor so that it cools the motor and then flows out of the pump outlet.
This pump is even in the case of close to the drainage sink, do not have to worry about the motor temperature, so the scope of application is growing. Outside the pump under the submersible pump directly from the impeller after the pressure chamber or guide leaf outlet at the exit of the liquid, the motor is also pumping the liquid cooling. As the lower pump structure can work in the lighter liquid, it is often used in the operating surface submersible pump, especially it is the main structure of large diameter submersible pump type. The mechanical seal of the submersible submersible pump is located in the high pressure zone of the outlet water. The higher the head is, the higher the water pressure here, so the performance of the mechanical seal is controlled by the head.
