Ensure good lubrication and maintenance of wearing parts when maintaining wear and acid resistant pumps
Wear and acid resistant pump maintenance must ensure good lubrication
Whether the wear-resistant and acid-resistant pump adopts rolling bearings or sliding bearings, good lubrication is required, and the contact parts of the bearings must be coated with oil film at all times. First of all, choose the lubricants required by the equipment manufacturer. Secondly, it is necessary to prevent the lubricating oil from being contaminated by water. Studies have shown that as long as the water content in pure mineral oil is 10-20%, the fatigue life of bearing races and rolling elements will be shortened by 48%, so once the bearing parts are found to be corroded or The lubricating oil has emulsified and should be replaced with new oil as soon as possible. Finally, it should be noted that in the maintenance, the rolling bearing should be prevented from adding excessive lubricating grease. Excessive grease will cause the bearing's heat dissipation performance to deteriorate, which may eventually lead to bearing failure. Some sliding bearings have installation requirements for the direction of rotation. It should be confirmed that the direction of rotation must be consistent with the direction of rotation of the rotor. The wrong installation direction will cause the bearing to fail to establish a stable oil film, deteriorate the lubrication state, and shorten the operating life of the bearing.
Wear-resistant and acid-resistant pump
Wear and acid resistant pump maintenance should strengthen the maintenance of wearing parts
The wearing parts of wear-resistant and acid-resistant pumps include sealing rings, oil cups, gaskets everywhere, etc. We must not only pay attention to the maintenance and replacement of important spare parts, but ignore the inspection and replacement of wearing parts. A wear-resistant and acid-resistant pump of a certain company was put into operation without carefully checking whether the sealing gasket of the oil cup interface was intact after being overhauled. As a result, the lubricating oil of the pump gradually leaked through the aging oil cup gasket, which eventually caused the lubricating oil Light leakage causes bearing seizure.
