If errors occur during the installation of a chemical dosing pump, it may prevent the entire system from functioning properly. Therefore, it is essential to read the instructions carefully when installing such a pump. So what kinds of errors can occur during installation? If the length of the inlet pipeline of the chemical dosing pump is too long, it will increase the pressure loss in the inlet line, thereby leading to cavitation. In this case, it is necessary to adjust the installation position of the metering pump, increase the length of the outlet pipeline, and shorten the length of the inlet pipeline. Alternatively, increase the diameter of the inlet pipe of the metering pump to reduce the pressure losses in that pipe and prevent cavitation from occurring. The bend at the top of the inlet pipeline of the chemical dosing pump – this incorrect installation method leads to gas buildup in the bend, preventing proper absorption of liquid. At this point, it is necessary to change the location of the inlet pipeline of the metering pump, leading it out from the bottom of the solution tank. Alternatively, an elevated installation method can be adopted by adding a foot valve at the bottom of the inlet pipeline of the metering pump. Siphoning occurs during the installation of the dosing metering pump. This condition results in insufficient pressure difference between the outlet and inlet of the metering pump, allowing the solution to flow from the inlet to the outlet when the pump is not in operation. The standard procedure in this case is to install a back pressure valve in the pipeline at the outlet of the metering pump, thereby creating a pressure difference in that pipeline and preventing siphoning from occurring. The installation position of the pulsation damper on the chemical dosing pump is incorrect; this prevents the buffer from functioning properly and prevents the elimination of pulses in the pipeline. At this point, it is necessary to swap the installation positions of the pulse damper and the backpressure valve, installing the pulse damper between the backpressure valve and the outlet of the metering pump.
