Micro peristaltic pump is used for the selection of cement grinding aid

Cement grinding aid is a kind of chemical additive which can improve the grinding effect and performance of cement.Common cement grinding AIDS are liquid and powder two kinds,of which solid grinding AIDS in the early application of more,due to dust pollution,solid cement grinding AIDS will gradually transition to liquid grinding AIDS.

The advantage of micro peristaltic pump is that the liquid itself does not contact the pump body,easy to clean.However,the micro peristaltic pump needs to replace the hose regularly.In order to improve the working efficiency,reduce the cost of consumables and reduce the frequency of tube change.The life of the micro peristaltic pump hose has become a major consideration in the selection of peristaltic pump.

The peristaltic pump tube for the transmission of cement grinding aid can meet the demand with silica gel tube,without import and export pipe,but the majority of users may have such a question:the hose material is the same,the same specifications,the same life must be the same?The answer is no,in addition to the material of the hose itself,another very important factor is the performance of the pump head and speed.

Micro peristaltic pump is to work by squeezing the hose,and the hose to reach the life is often extrusion fatigue damage,that is,the hose is squeezed limit number of certain,so the higher the speed,the shorter the life will be.This theory tells us that when choosing peristaltic pump,if there is no special requirement,the thicker pipe should be selected as far as possible,so that the flow rate can be met at a lower speed.Thus to achieve the purpose of improving the hose life.

Another factor that needs to be considered is the performance of the pump head itself,whether the pressure can be adjusted,whether the pressure tube gap is uniform.The pressure adjustment prevents the hose from being overpressurized and unable to release,or the pressure is not enough to prevent transmission.When the hose is overpressurized,the life will be shortened exponentially,seriously affecting the normal work,and in the case of negative tolerance of the hose,or working for a period of time,the pipe wall becomes thin,it may lead to insufficient pressure,or even no water.

The uniformity of the pressure tube clearance is also a factor to consider,due to the principle of micro peristaltic pump decision in the process of work to ensure the whole sealing,so will be adjusted based on low pressure not leak pressure,if uneven pressure tube clearance will lead to high and low pressure difference is big,the hose will be part of the overvoltage,then this part of the hose will be reached first life.
