Installation b is different, vertical pump for the overall connection, installation is easier, and horizontal pump after installation needs to be adjusted for precision. Maintenance difficulty is different, vertical pump maintenance is difficult, such as maintenance impeller need to remove all the upper part can be carried out, and horizontal pump is relatively easy. In the process of opening the pump in use, sometimes it will appear blockage phenomenon, then how should we solve it? Here's a specific introduction for you. To ensure the safe operation of critical equipment in the pump is mainly used for catalyst injection, to promote the polymerization in the pre-condensation kettle, the final condensation tank in the condensation reb. Polyester process requires that the catalyst must be in a certain proportion of people, and the stop time can not exceed 15rain, otherwise the melt viscosity will be reduced, product quality and so on. In order to ensure the smooth operation of the catalyst pump, some guarantee measures must be taken. Regular replacement of lubricating oil and wear parts pump internal main moving parts have worm, worm wheel, slider, fixed new piston and so on. Wear of these components will directly result in reduced pump flow or no amount at all.
