Analysis of the associated maintenance of a self-priming stainless steel pump

Made of stainless steel, the self-priming pump features simple and reliable structure and is durable. Under normal conditions, the pump generally does not require frequent disassembly and maintenance. LN0Textile Testing Instruments, Testing Equipment Manufacturer


If an error is detected, it can be fixed at any time. LN0Textile Testing Instruments, Testing Equipment Manufacturer


1. There are several main parts to consider when servicing the pump: LN0Textile Testing Instruments, Testing Equipment Manufacturer


a. Roller bearing: LN0Textile Testing Instruments, Testing Equipment Manufacturer


After the pump has been in operation for a long time, the bearing must be replaced if it is worn to a certain extent. LN0Textile Testing Instruments, Testing Equipment Manufacturer


b. Front O-ring, Rear O-ring: LN0Textile Testing Instruments, Testing Equipment Manufacturer


When the O-ring wears to a certain extent, it must be replaced. LN0Textile Testing Instruments, Testing Equipment Manufacturer


c. Mechanical seal: LN0Textile Testing Instruments, Testing Equipment Manufacturer


If the mechanical seal is not leaking, should it generally not be dismantled?LN0Textile Testing Instruments, Testing Equipment Manufacturer


Check. If severe leakage occurs at the leakage port at the bottom of the bearing body, the mechanical seal should be inspectedtion to be disassembled. LN0Textile Testing Instruments, Testing Equipment Manufacturer


When assembling and disassembling the mechanical seal, be careful with it, pay attention to cleaning the mating surface, protect the mirror surface of the static ring and moving ring, and strictly prohibit shock and collision. LN0Textile Testing Instruments, Testing Equipment Manufacturer


The main reason for the mechanical seal leaking is the brushing of the mirror surface due to friction. LN0Textile Testing Instruments, Testing Equipment Manufacturer


The repair method is to grind the friction end face to restore the mirror surface. LN0Textile Testing Instruments, Testing Equipment Manufacturer


Another reason for the mechanical seal to leak is that the “O” shaped rubber sealing ring (or cushion) is improperly installed or has become deformed and aged. At this point, the reassembly o-ring must be adjusted or replaced.LN0Textile Testing Instruments, Testing Equipment Manufacturer


2. Sequence of disassembling the pump: LN0Textile Testing Instruments, Testing Equipment Manufacturer


a. Remove the motor or detach the clutch.LN0Textile Testing Instruments, Testing Equipment Manufacturer


b. Remove Sie the bearing body assembly, check the radial clearance between the impeller and the front mouth ring and check if the impeller nut is loose.LN0Textile Testing Instruments, Testing Equipment Manufacturer


c. Remove the impeller nut, pull the impeller out and in Check the impeller and rear O-ring. LN0Textile Testing Instruments, Testing Equipment Manufacturer


d. Loosen the mechanical seal fixing nail, pull out the moving ring portion of the mechanical seal, check the seating of the end faces of the moving and static rings, and check the sealing condition of the “O” ring (or cushion).LN0Textile Testing Instruments, Testing Equipment Manufacturer


e. Unscrew the coupling retaining nut and pull out the coupling.LN0Textile Testing Instruments, Testing Equipment Manufacturer


f. Remove the bearing cover and remove the pump shaft and bearing.LN0Textile Testing Instruments, Testing Equipment Manufacturer
