Dosing metering pump does not water how to do?

Dosing metering pump is a measure of the liquid transport machinery, often used to add all types of pharmaceuticals complete sets of equipment, it is also called dosing pump. When the inlet pipe and the pump body air, it will lead to dosing metering pump without water. What should we do now? Here we talk about dosing dosing pumps do not water how to do? (1) The dosing pump has not been filled with enough water before it starts. Sometimes it appears that the water has been spilled from the bleed hole, but the air is not completely discharged by the pump shaft, causing a little air to remain in the inlet pipe or the pump body. (2) The dosing pipe should contact the dosing pump at a level of 0.5% or more of the descending slope in the direction opposite to the water flow. Connect the dosing pump at the inlet end with the highest level, not the full level. If you tilt up, there will be trapped air intake pipe, reducing the vacuum pipe and dosing metering pump, affecting water absorption. (3) Dosing dosing pump due to wear or long-term use of packing has been too loose, resulting in a lot of water from the gap between the filler and the pump shaft sleeve ejected, the result is that the external air from these gaps into Canada Medicine metering pump internal, affecting the water. (4) Inlet pipe Due to long-term potential underwater, pipe wall corrosion holes, dosing metering pump water surface after work continues to decline, when these holes exposed water, the air from the hole into the civilian into the water pipe. (5) There is a crack in the inlet pipe bend, there is a slight gap between the inlet pipe and the dosing pump connection, which may make the air enter the inlet pipe. The above is when the inlet pipe and the pump body air, dosing pumps do not water how to analyze and hope that we can give you some help!
