The Slurry pump would be work long time if they are assembled reasonable and maintenance in time
1, Slurry Pump Shaft Seal Maintenance
Packing seal pumps should regularly check the seal water and pressure, and always maintain a small amount of clean water flow through the shaft. To make this, you have to adjust the packing gland on a regular basis,. if the filler cannot be re-used, should be replace all.
Expeller sealed pumps use oil cup, more economical, but need to regularly lubricate sealed chamber, rubber expeller ring need not lubrication(some pumps exceptions).
2, Impeller Adjustment
The pump performance becomes deterioration as the open impeller and the suction side of the plate gap increasing. This impact for closed impeller pump is not obvious, but there are exceptions.
Due to wear flow, the gap increases and pump efficiency is reduced. In order to maintain the high efficiency of the pump, impeller must be timely moved forward, this adjustment just a few minutes and without disassembly any parts.
After adjusted, it need to check the impeller rotation before start the pump,and also check the bearing housing fastening bolts are tightened.
3, Bearing Lubrication
Bearing components properly assembled and pre-grease lubrication, after shaft-mounted to the bearing housing. If there is no water of other sundries intrusion and timely maintenance, the hearing components are not only reliable but also long life.
Maintenance technician must check the bearing box to observe the bearing and grease regularly.
The number of regular lubrication and the injection of grease depends on many factors and the interaction of them. They are include speed, bearing specifications, continuous working hours, the pump stop and work time ratio, the working environment. For example, cycle and operation temperature, splash, contamination of the presence of impurities.
Most of the pump hearings run low speed, but there is the risk of damage, mainly due to excessive lubrication of bearings, but preventive measures of avoiding excessive lubrication cannot completely guarantee the maintenance of bearings, the ultimate deciding factors are lubrication experience and judgment to determine the lubrication program, the better approach is to persistent observation the early stages of bearings operation, carefully recorded the unusual circumstances, for example, temperature and purity.
For continuous operation, the bearing operating temperature shall not exceed the grease to lose its sealing ability.
4, Replacement of Wearing Parts
The slurry pump bearing wear rate is a function of abrasive characteristics and materials of pump and working conditions. The life of wearing parts such as impeller, volute liner, frame plate liner, throat bush are different.
When the pump performance cannot meet the requirements, the wearing parts must be replaced.
When the pump is first to be used for specific conditions, accident may happened especially during this operation cause of bearing parts losing effectiveness, you should regularly check the pump and bearing wear, to estimate the degree of wear in order to estimate its useful life.
5, Standby Pump Maintenance
The standby pump should be turned 1/4 rotation a week, in this way, all bearing rotation under static and external vibration.
