Whether you're a seasoned professional or just starting out in the world of slurry pumping, this article is sure to provide valuable insights and information. Dive in and learn all about positive displacement slurry pumps!Positive Displacement Slurry Pump: A Comprehensive Guide by CNSME PUMP to Positive Displacement Slurry Pump In the world of industrial pumping, the positive displacement slurry pump is a crucial piece of equipment that is responsible for handling abrasive and viscous fluids. These pumps are designed to efficiently transport slurry, which is a mixture of solid particles and liquid, in various industries including mining, construction, and wastewater treatment. At CNSME PUMP, we specialize in manufacturing high-quality positive displacement slurry pumps that are known for their reliability and durability. Understanding How Positive Displacement Slurry Pumps Work Unlike centrifugal pumps that rely on kinetic energy to move fluids, positive displacement pumps work by trapping a fixed amount of fluid and then displacing it into a discharge pipe. This results in a constant flow rate regardless of changes in pressure or viscosity. In the case of slurry pumps, the abrasive nature of the slurry can cause wear and tear on the pump components. However, at CNSME PUMP, our pumps are designed to withstand the harsh conditions of slurry pumping and deliver superior performance.

Horizontal slurry pump is a commonly used equipment in ore dressing process and is mainly used for ore slurry transportation.If the improper use of horizontal slurry pumps is likely to affect their normal operation and their production capacity.So what should we do when there is a problem with the horizontal slurry pump? Let’s take a look at it with the editor: 1. The lubricant is not clean, causing problems such as bearing friction, wear, heating, vibration, etc. You can lubricate various parts of the bearing to reduce friction and wear. The quality of the lubricant must be checked regularly to enter dust or oil aging and deterioration.The lubricating oil should be adjusted strictly in accordance with the pump instruction manual. It should not be too much or too little. If there is too much oil, most of the friction heat inside the bearing cannot be taken away, which will not play an effective role in heat dissipation, and will also increase the temperature rise of the bearing; if there is less oil, it will cause the bearing oil film to rupture and dry friction, burn the bearing.2. During the use of the horizontal slurry pump, the seal failed due to packing wear, and the slurry leaked along the shaft seal. The slurry instantly filled the semicircular positioning hole curved surface of the bracket and the rear pump shell. The slurry discharged from the discharge port could not be sealed into the oil pool through the water barrier plate, causing bearing damage.During daily maintenance, attention should be paid to regularly detecting the leakage of shaft seal water. When the leakage amount increases, the bolts of the filler gland should be adjusted, and the packing and failed O-rings should be replaced in time to prevent leakage slurry from leaking from the waterproofing plate sealing into the bracket oil tank along the shaft.3. Long-term use of horizontal slurry pump causes scaling on the surface of the cooler pipe wall, resulting in poor heat transfer; the cooling water volume is small or no cooling water is added.Therefore, it is necessary to check whether the bearing cooling water pressure and flow rate are suitable. Generally, the cooling water pressure of the horizontal slurry pump is 0.05~0.2MPa, and the cooling water flow rate is 1~3m3/h. Change the scaling cooler in time, turn on the cooling water before the pump starts to adjust the pressure to the specified value, check the bearing temperature rise (35℃) regularly, and the highest temperature shall not be greater than 75℃.The minor problems with these horizontal slurry pumps will have a great impact over time and should be inspected in time and repaired in time to ensure their normal use.1. During use, the slurry pump fails due to packing wear, and the slurry leaks along the shaft seal. The slurry instantly fills the semicircular positioning hole curve of the bracket and the rear pump shell. The slurry discharged from the discharge port can not have time to seal into the oil pool through the water barrier plate, or the cooler welding joint is not welded, and water enters the oil pool, contaminating the working oil in the bracket oil pool, causing bearing damage.During daily maintenance, attention should be paid to regularly detecting the leakage of shaft seal water. When the leakage amount increases, the bolts of the filler gland should be adjusted, and the packing and failed O-rings should be replaced in time to prevent leakage slurry from seeping into the bracket oil pool from the waterproofing plate seal along the shaft, and the cooler joints should be replaced or re-welded.2. If a foreign object is blocked in a single-bore channel of the pump, the impeller will lose balance, which increases the thrust to one side, or the base bolt of the pump is loose, causing the pump to vibrate and even damage the pump's bearing. If the above problems occur, the blockages in the impeller bolts should be cleaned in time; check the tightening of the pump on the basis of the pump, and the anchor bolts should be firm and reliable.3. Generally, the bearings of the slurry pump are lubricated and cooled by a dilute oil, and the oil is also cooled by a built-in surface cooler. The cooler material is pure copper tube, and the cooling medium is circulating water.When the surface of the cooler pipe wall is fouled, it will cause poor heat transfer and lead to poor cooling effect.Therefore, it is necessary to check whether the bearing cooling water pressure and flow rate are suitable. Generally, the cooling water pressure of the slurry pump is 0.05-0.2MPa and the cooling water flow rate is 1-3m/h. Change the scaling cooler in time, turn on the cooling water before the pump starts to adjust the pressure to the specified value, check the bearing temperature rise (35%) regularly, and the high temperature shall not be greater than 75%.4. Lubrication has an important impact on the fatigue life of rolling bearings and friction, wear, temperature rise, vibration, etc.By lubrication of various parts of the bearing, friction and wear can be reduced.When the lubricant oil is not clean, too much oil or too little oil, and the oil ages and deteriorates, the bearing heat will be greater than before during operation. Too much oil is prone to leakage. At the same time, too much lubricant cannot take away most of the friction heat inside the bearing, and it will not play an effective role in heat dissipation, causing the bearing temperature to increase; too little oil will cause the bearing oil film to rupture and dry friction, burning the bearing.The oil volume should be adjusted strictly in accordance with the pump instruction manual, and regularly check whether the oil level in the bracket is suitable. The correct oil level should not exceed 2mm near the oil level line. If the oil seal fails or oil leakage occurs, the oil volume should be replenished in time.
