Parameters required for selection of corrosion-resistant sewage pump
Corrosion-resistant sewage pumps are more and more widely used. The representative product is WQ stainless steel submersible sewage pumps. Corrosion-resistant sewage pumps are becoming more and more subdivided, and many customers do not know how to choose their own corrosion-resistant sewage pumps. In fact, the selection of corrosion-resistant sewage pump can only be selected by mastering the basic parameters, such as caliber, flow, head, power, voltage and liquid.
WQ stainless steel submersible sewage pump
First of all, choose a suitable corrosion-resistant sewage pump according to the discharge flow rate and the size and height of the head.
The second is to choose a corrosion-resistant sewage pump based on different applications. For example, when sending sewage with high sand content, choose a corrosion-resistant sewage pump with good wear resistance. Choose corrosion-resistant pump: When transporting fiber materials, consider the corrosion-resistant sewage pump with cutting mechanism.
Three, choose single-phase or three-phase corrosion-resistant sewage pumps according to different power sources.
Fourth, according to the requirements of use, no matter whether the liquid needs to be completely emptied or not, the upper pump type or the lower pump type must be selected.
Fifth: According to factors such as price, quality status, operating cost, installation and maintenance convenience of corrosion-resistant sewage pump, the appropriate pump is selected.
Sixth: On the premise of energy saving and meeting the requirements of use, a corrosion-resistant sewage pump with higher efficiency is selected, and the parameters of the selected corrosion-resistant sewage pump are operated within the range of 0.7-1.2 times the rated flow
Seventh: Check whether the corrosion-resistant sewage pump has a reliable grounding device and safety protection device, so as not to affect the safe use of the corrosion-resistant sewage pump.
Eighth: When choosing, pay attention to check the appearance of the pump, check whether the corrosion-resistant sewage pump body, pump cover is damaged, whether the cable is damaged, whether there is corrosive agent on the surface of the pump, whether the bolts are loose, whether there are traces of electrical leakage or water leakage, and there should be Megger measurement-cold insulation resistance, the installation standard stipulates that the cold insulation resistance is above 50 megohms.
