A collection of common problems with slurry pumps for customers to read. CNSME Slurry Pump Company has received feedback from customers before asking our technicians what issues should be paid attention to when using slurry pumps?In fact, slurry pumps are suitable for a variety of complex working conditions. The working characteristics of slurry pumps are that the slurry processed mostly contains various solid particles, which requires us to know more about the precautions for use in daily operations. Today we will talk about the precautions for use of slurry pump ore dressing.1. Maintenance of shaft seals for slurry pump ore dressing. The shaft seal pump should regularly check the seal water pressure and water volume when dressing the slurry pump, and always keep a small amount of clean water flowing along the axis. Regularly adjust the filler gland, check the filler and replace the filler regularly. The shaft seal water pressure and the shaft seal water volume should meet the above requirements (shaft seal inspection).For secondary impeller shaft sealing pumps equipped with oil cups, oil should be regularly filled with oil cups to lubricate the internal filler or lip sealing ring.2. Adjustment of impeller for slurry pump ore dressing　In order to ensure the pump operation, the gap between the impeller and the front guard plate must be adjusted in time. The gap between the metal-lined pump impeller and the front guard plate is between 0.5-1mm, and the gap between the rubber-lined pump impeller and the front and rear sheath must be equal.3. Use bearing lubrication when slurry pump ore dressing. When slurry pump ore dressing, the operating life will be longer if the assembly is correct, the lubricating oil is appropriate, and the maintenance is timely. Maintenance personnel should regularly inspect the bearing components and check the conditions of bearings and greases. The maintenance interval generally does not exceed 12 months.Slurry pumps are widely used in important basic departments such as mining, metallurgy, coal, hydraulics and transportation. During the process of transporting solid-liquid mixtures such as slurry, cinders and mud, they are impacted by solid particles, and their overflow parts cause severe wear, resulting in a shortening of the service life of the slurry pump and affecting the normal operation of the equipment.Therefore, reducing the wear of the slurry pump overflow parts is the key in actual production.Generally, in practical applications, the main measures to reduce the wear of the slurry pump overflow parts are as follows: 1) Use reasonable impeller geometric parameters: In order to meet the required head and reduce wear, a larger blade inlet diameter and outlet width are selected, which reduces the relative speed at the inlet of the impeller, reduces the wear of the impeller, and prevents blockage.2) Reasonable matching of volute shell and impeller: If the shape of the slurry pump volute shell is unreasonable, it will accelerate wear. When designing, you should consider matching with the impeller. While meeting the pump performance, try to keep the liquid flow rate in the volute as small as possible, otherwise the wear will be very serious.3) Reasonable selection of materials for considering the characteristics of the medium: The service life of the slurry pump is largely related to whether the selected material is appropriate.During the material selection process, the geometry and particle size of the solid particles in the slurry should be fully considered. If the solid particles are small and have regular shapes, the particles are evenly distributed and there are no sharp sharp objects, non-metallic materials such as rubber and engineering plastics can be selected to ensure good wear resistance while also reducing costs.When the geometry of solid particles in the slurry is extremely irregular and the particle size composition is widely distributed, materials with high hardness and good wear resistance should be selected, such as hard nickel and high chromium cast iron materials, because such materials have certain advantages in resisting the wear of solid particles in the slurry.4) Adopting a reasonable anti-wear structure: Adopting a reasonable structure is an effective way to slow down the wear of the slurry pump.For example, setting up linings, thickening bushings and impellers, setting up secondary blades and secondary impellers can also reduce wear.There are three functions of cooling water in the slurry pump, namely cooling, cleaning, and lubrication and maintenance.So how to grasp the cooling water usage in the slurry pump?The cooling water usage of slurry pump is affected by the machine seal type, pump type, and pump pressure factors. Let’s talk about the rules and reasons of the influence of these three factors: 1. Mechanical seal of slurry pump. There is a mechanical seal of slurry pump. In this case, there is no need to add cooling water.Both internal flushing mechanical seals and external flushing machine seals require cooling water with a slurry pump.2. Slurry pump type factors The amount of cooling water for the slurry pump gradually increases as the pump type increases, that is, the larger the pump type, the greater the cooling water for the slurry pump.3. Slurry pump pressure factors The greater the pump pressure, the greater the cooling water used in the slurry pump, which is proportional to the pressure.In view of the above three situations, the cooling water consumption of the slurry pump is affected by the pump parameters. The specific usage reference table is too complicated and will not be listed one by one here. If you have any specific questions, please contact our customer service for you. Of course, if there are other knowledge that slurry pumps want to know, you are welcome to call and we will answer them one by one!

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.

When using a slurry pump, you should pay attention to maintaining its good sealing effect. There are two types of sealing components of the pump: pump housing seal and shaft seal.The pump housing seal uses a front and rear guard plate \"0\" ring seal, and the shaft seal uses an auxiliary impeller mechanical seal.The pump housing seal should be tightly pressed on the \"0\" ring in the front and rear guard grooves to achieve the effect of the pump housing seal. The shaft seal is a mechanical seal that connects the auxiliary impeller to achieve the shaft seal effect.　　So why should we pay attention to keeping the slurry pump sealed?This is because the operation, leakage, dripping and leakage caused by poor sealing of pumps, serious consequences include: after fluid enters the pump bearing, it will dilute and change the quality of the lubricant, aggravate bearing wear, cause vibration, and shorten life.So we must keep it in good sealing condition when using it!In our industrial production process, such as centrifugal slurry pumps, the sealing effect of the pump should be well completed.The packaging of the filler box should be sealed, and the packaging of the filler box should be replaced and the cap should be pressed regularly. If mechanical seal is used, more attention should be paid to prevent vibration of the pump and pipes, and the sealing water should be carefully checked to prevent overheating and damage to the mechanical seal.The problem that still needs to be paid attention to is to choose a mechanical seal installation and consider the material of the dynamic and static ring to resist the corrosion of the working medium.
