Technical essentials for the installation and use of pumps.
1.During installation, a layer of clean mechanical oil should be applied to the surface in contact with the mechanical seal, so that the installation can be smoother2.The sealing cavity part of the equipment should be kept clean during installation, and the sealing parts should be cleaned to keep the sealing end face intact and prevent impurities and dust from being brought into the sealing part3.During the installation process, it is strictly forbidden to knock and bump to avoid seal failure caused by mechanical seal breakage;4.The stiff runout of the rotating shaft of the equipment should be less than or equal to 004 mm, axial channeling momentum is not allowed to be greater than 01 mm;5.When installing the static ring gland, the tightening screw must be evenly stressed to ensure that the end face of the static ring is perpendicular to the shaft6.After installation, push the moving ring by hand, so that the moving ring can move flexibly on the shaft, and have a certain elasticity;7.After installation, use the hand to move the hinge, the hinge should not feel light and heavy;8.Before operation, the equipment must be filled with media to prevent dry friction that could cause the seal to fail
9.For the easily crystallized and granular media used in the non-clogging sewage pump, when the temperature of the medium is greater than 80, corresponding washing, filtration and cooling measures should be taken. For all kinds of auxiliary devices, please refer to the relevant standards of centrifugal pump mechanical seals.
10.During operation, if there is any abnormal situation, it should be stopped immediately to check and troubleshoot;
11.During operation, the friction surface of the mechanical seal should be checked frequently to see if it is clean, whether there is wear and crack, and whether the sealing fluid is normal
12.In the event of a shutdown, the discharge valve of the pump should be closed first, and then the power supply should be cut off
13.After the shutdown, the pump should be checked frequently to see if all parts of the pump are in good working order and kept clean;
14.In the process of use, if the performance of the pump is abnormal, it should be stopped immediately for inspection, and the fault can be eliminated before it can be used again
15.During use, attention should be paid to the maintenance and upkeep of the pump to ensure its normal operation.
