The Maintenance Of The Wearing Parts Is Good, Which Can Save A Lot Of Trouble For The Maintenance Of

In order to extend the service life of the slurry pump, we need to strengthen its daily maintenance.Since some of its parts are consumable parts, the wear of the consumable parts must be carefully observed during use and repair or replace them in time.The consumable parts are maintained, and the pump body is really worry-free.  1. The pump shell is generally cast iron, which is susceptible to mechanical or thermal stress and is not easy to break. When the mud pump freezes due to cavitation during work or the water from the pump shell is not released in winter, it is also easy to break. If the damage is too large and cannot be repaired, a new pump shell should be replaced.2. The pump shaft is usually made of carbon steel, but it is easily damaged due to the quality of manufacturing, use or installation.The pump shaft may have cracks, bends, wear of the journal, and damage to the threads. It may also cause a fracture accident. In case of serious damage, do not replace the shaft.3. The impeller of the slurry pump is an important working part and is made of cast iron.It is also easy to damage due to manufacturing quality and use reasons, the impeller may have cracks, and due to cavitation, the surface of the impeller may appear dents or perforations, and the blades will become thinner or eccentricly worn for a long time, or even be damaged by debris. Some defects can be repaired, and some defects cannot be repaired, that is, a new impeller should be replaced.4. The bearing bushing of the sliding bearing is made of copper-tin alloy, with poor wear resistance and is one of the easily wearable parts that are easy to wear and flammable.Usually, bearing bushings can be repaired or replaced with new ones, and the average service life of rolling bearings is 5000 hours, but they are prone to wear or damage due to improper installation, long service life or poor maintenance.In addition to replacing the parts of the rolling bearing with new parts, the overall parts usually need to be replaced.5. The oral ring is also called a ring that reduces leakage or wear. It is one of the components that are prone to wear.Wear can be repaired or replaced with a new one. After replacing the new leakage reduction ring, its inner diameter should be configured according to the outer diameter of the impeller inlet.If the outer diameter of the impeller inlet is worn, it can be rotated to eliminate groove marks and ovals, and then a leak reduction ring with reduced inner diameter is configured.6. When using filler sealing gasket, the filler will harden for a long time and lose elasticity, which will cause the slurry pump to leak air and water.Usually, new packaging should be replaced.7. Oil seals are rubber products that are prone to wear and aging, and generally require new parts to be replaced.

Horizontal Slurry Pumps: Principles & Application
Because they offer longevity, efficiency, and adaptability, horizontal slurry pumps are crucial for sectors handling abrasive slurries. Knowing their values, applications, and maintenance needs allows businesses to maximize performance and reduce expenses.
Commissioning of Slurry pumps
Slurry pump commissioning must be strictly conducted in accordance with established procedures: Prior to startup, first activate the shaft seal water and adjust it to the specified pressure. Fully open the inlet valve. For non-backflow pumps, water must be injected. After opening the outlet valve to one-quarter, initiate startup; During operation, monitor flow rate, head, current, vibration, and bearing temperature (temperature rise ≤35°C, maximum ≤75°C). Mechanical seal leakage should be ≤3-5 ml/h. Before stopping the pump, flush with clean water for 30 minutes, close the outlet valve first, then shut down the pump, and finally close the shaft seal water and inlet valve. It is strictly prohibited to fully open the outlet valve when stopping the pump to prevent water hammer. Throughout the entire trial operation process, ensure that parameters remain stable, avoid cavitation and overload conditions, to ensure safe operation of the equipment.
Common Problems During Feeding of Slurry Pumps
When a slurry pump malfunctions during operation, the first step is to identify the cause of the failure. Corresponding repair measures should be taken based on the characteristics of the failure and maintenance experience.
Aspects to Pay Attention to for Slurry Pumps to Run Stably and Efficiently in Series

The advantage of slurry pumps in series is that multiple pumps are arranged in one pump station, which is convenient for installation, maintenance, operation and management, with a total low cost, it can realize overall automatic management. The following aspects should be noted when selecting slurry pumps in series:
The Hazards to Slurry Pumps if Running in a Low Flow Area for a Long Time
The slurry pumps we often use are a type of centrifugal pump. It mainly drives the slurry mixture to rotate through the high-speed rotating impeller blades, and throws out the slurry to achieve the purpose of transportation.
The methods for adjustment the flowrate of slurry pumps
The flowrate adjustment method of slurry pump can be selected in various ways according to different needs and occasions. The following are some common flowrate adjustment methods:
Five Main Reasons for the Blockage of Slurry Pumps
Uneven medium density is one of the reasons for the blockage of slurry pumps. When the medium density is uneven, the pump may vibrate at the beginning of the startup, but this vibration usually disappears when the pump starts normally.
