How to install fluorine plastic self-priming pump, should pay attention to what?

Fluorine plastic self-priming pump is lined with fluorine plastic ( F46） Outside the cast steel after high temperature casting and become, has the very good corrosion resistance, applicable to arbitrary concentrations of acid, alkali, salt and other corrosive liquid fluorine plastic pump. So how to install? Pay attention to what? 1, when installing fluorine plastic self-priming pump should strictly check the pump shell and pipe in the presence of stones, iron ore and other sundry. Should keep pumps and piping electrostatic grounding resistance to achieve the requirements of the regulations. 2, fluorine plastic self-priming pump coupling must use nut good solid, and lock nut, watch the nut loose, otherwise easy to cause impeller channeling, cause mechanical failure. 3, in the self-priming pump and motor to drive straight league, alignment of pump shaft and motor output should be paid attention to; Accuracy for water pump pump installation and service life of the running smoothness of conveyor chains have great influence, so we must carefully install correction. Correction self-priming pump coupling and electric motor coupling installation clearance and alignment, it does not allow axiality deviation is 0. 1mm。 The height of the pump shaft and motor shaft general on foot pad copper or iron. To make the self-priming pump body can maintain a certain liquid storage, in order to achieve good self-priming ability and prevent dry friction of mechanical seal, must make the water pump inlet is higher than the pump shaft centerline. 5, self-priming pump bearing body every room is equipped with cooling device of the cooling water joint distribution of inner hole for 12 hose or plastic pipe, the thread sizes for M12x1. 75. 6, on the road at the outlet pipe of self-priming pump, such as a one-way valve and in the process of imbibition cannot make pump discharge gas smoothly, should be added at the exit of the pump exhaust pipes and valves. 7, the suction pipe installation should be paid attention to: A, suction installation height can't more than 5 meters, when conditions permit, suction installation height should be below the lowest water pool plane as much as possible, and try to shorten the length of the suction pipe, short-ship elbow, it is beneficial to shorten the self-priming time, improve the function of self-priming. B, in the suction pipe valves, flange, etc. Shall be protected from leakage or leakage of liquid in the suction line does not allow to have the air leakage phenomenon exists. C, should prevent the inhalation of solid in the pump body and other sundry, for this suction filter should be set up on the road. The area of effective water filter should be 2 - suction pipe section Three times, the filter should be check regularly. D, suction pipe and spit out line should have their own support, pump body itself is not allowed to bear load of pipeline. 8, in the actual operation 3 - unit 4 hours after the check, if there is no negative phenomenon, the main for the installation has been completed, check the shaft in the test run.
