1,Horizontal slurry pump accessories can be roughly divided into: slurry pump flow parts (namely, the part of the slurry pump contact liquid), slurry pump bracket part (also known as suspension), slurry pump base and slurry pump pump body pump cover, etc.

The slurry pump bracket part: The bracket body (suspension) is made of gray iron, belongs to the non-wearing parts, technical requirements are not high, and some parts of the general accessories, such as bearings, screws, bolts, oil plug, ring, oil mirror, belt, pulley, coupling, flange, washer, O-ring, mechanical seal, filler, nozzle and so on, generally do not need the slurry pump manufacturers own production.

Generally, the base of slurry pump can be welded and cut with iron plate according to the slurry pump with power motor, or cast according to the drawings.

Slurry pump pump body pump cover generally plays the role of protecting the slurry pump flow parts in the double pump shell slurry pump, which does not belong to the wearing parts.

So most of our customers and end users mouth mentioned slurry pump accessories in fact mainly refers to the slurry pump flow parts is usually called the four big parts: volute, impeller, front guard plate, rear guard plate, in addition to the slurry pump packing box and slurry pump auxiliary impeller is often replaced.

Slurry pump through the flow component is the core part of the slurry pump, is the slurry pump working operation and direct contact with the transmission medium of the accessories, so wear is the largest is the fastest replacement is the most frequent

When the rolling bearing is working, the inner seat ring is matched with the journal, and the outer seat is matched with the bearing seat, and the inner seat can be rotated during the work, but the rotation of the outer seat ring has a more serious impact on the bearing life, so the inner seat ring should be rotated as much as possible during the design.

In the rolling bearing with the inner seat rotating, the inner seat and the journal, the outer seat and the bearing seat must be over-matched, but the inner seat should be tighter than the outer seat, so that when the shaft is stretched due to the temperature increase in the work, it can have an adjustment effect. The bearing seat has enough steel to prevent the working life of the bearing from being affected by the deformation of the support.

When there are rolling bearings at both ends of the shaft, one end of the bearing can be fixed on the bearing seat, and the other end must have an axial clearance, which can produce axial movement in order to eliminate the influence of the change in the length of the shaft on the bearing.

After the desulfurization pump bearing seat ring is matched, the bearing cover is added outside, and the embedded flange is just against the bearing outer seat ring, and then the bearing cover is fixed on the bearing seat with screws. If the bearing is required to have the possibility of axial movement, there can be a gap between the bearing outer seat ring and the bearing cover, or a soft gasket can be added between the bearing cover and the bearing seat to adjust.

China's slurry pump suppliers will participate in MiningWorld Russia, a mining and mining machinery and equipment exhibition held in Russia from April 23 to April 25,Our booth number is C5021.

First, the selection method of slurry pump

The selection method of slurry pump is relatively simple, mainly according to the characteristics of the material to be transported and the transportation requirements. The following aspects need to be considered when selecting:

1. Material characteristics: mainly includes particle size, content, concentration, temperature, etc. Some materials with large particles or high concentration need to choose a large diameter slurry pump with large flow and high conveying pressure; Some materials with small particles or low concentration can choose a small diameter slurry pump with small flow and low conveying pressure.

2. Conveying distance and head: conveying distance and head determine the conveying capacity and working capacity of the pump, the farther the distance, the higher the head, the need to choose a large slurry pump with large power and large flow.

3. Output flow and transmission efficiency: the larger the output flow, the higher the transmission efficiency, but it also means that the energy consumption is higher. It needs to be selected according to the specific situation.

Two, the main parameters of the slurry pump

1. Flow rate: refers to the volume of liquid transported by the pump per unit time, the unit is m³/h or L/s, which is one of the important parameters of the slurry pump. According to the different conveying materials, the flow is also different, it is recommended to choose the flow that meets the actual needs.

2. Head: refers to the ability to overcome resistance to improve the liquid level height when transporting liquid, the unit is m or kPa. The larger the head, the more it can overcome the transmission resistance, but the more powerful the motor drive is required.

3. Speed: refers to the speed of the pump shaft rotation, the unit is r/min. In general, the higher the speed, the greater the flow of the pump, but the energy efficiency and service life will also be reduced.

4. Efficiency: refers to the proportion of the pump to convert the mechanical energy of the fluid. Efficient pumps reduce fuel consumption, noise and vibration when operating for long periods of time.

5. Sound level: also one of the important parameters. The lower the sound level, the smaller the noise, which is an important indicator of the safe and reliable operation of the slurry pump.

Third, the characteristics of different types of slurry pumps

1. Vertical slurry pump: suitable for conveying materials with higher concentration and larger particles, low noise, high pressure, and good wear resistance.

2. Horizontal slurry pump: suitable for conveying materials with low content and small particles, strengthening liquid flow power and increasing conveying capacity. At the same time, it is also widely used in seabed sediment extraction, artificial sand and pebble transportation and ordinary sand and pebble transportation.

3. High pressure slurry pump: suitable for conveying long distance, high head, high conveying pressure of large engineering occasions, is an indispensable important equipment in petroleum, chemical, mining, metallurgy and other industries.

Four, slurry pump maintenance and maintenance

1. Clean the liquid pipeline and the inside of the pump body to ensure that there is no caking, sediment and water accumulation.

2. Replace the liquid pipeline frequently to avoid long-term load transportation.

3. Regular maintenance and inspection of the rotor, bearing, seal, mechanical seal and other parts of the slurry pump, timely replacement of damaged parts.

4. Keep the pump body clean and check regularly to avoid damage and failure.

5. Prevent slurry pump overload and media backfilling, adjust pump output parameters in time to prevent performance degradation and failure.

The above is about the selection method of slurry pump, parameters, characteristics and maintenance and other aspects of the introduction, hope to be able to buy or use slurry pump users to provide a certain reference.
