[0040] High chromium wear-resistant white cast iron A05:

[0041] The material has high hardness, and the hardness after heat treatment is ≥HRC58. The high wear resistance of A05 alloy is due to the presence of hard chromium carbides in its structure.

[0042] A05 has good hardenability, good corrosion resistance and high temperature oxidation resistance, can withstand abrasive wear with large impact loads, and is suitable for heavy abrasive conditions with a pH value of 5 to 12.

[0044] Elastic materials have excellent anti-abrasion ability in fine-particle slurries. Rubber has great elasticity and can deform under external pressure. After releasing the load, it can return to its original state. It is suitable for conveying fine particles without sharp corners. Natural rubber is the most commonly used rubber wear-resistant and corrosion-resistant material. It is suitable for conveying dilute acidic and alkaline abrasive and corrosive slurries. The temperature generally does not exceed 70°C.

[0045] How to make the pump run efficiently:

[0046] 1. Select the pump reasonably according to the actual working conditions to make the pump work in the high efficiency range.

[0047] 2. Various impeller types. For low-abrasion working conditions, comprehensive consideration is given to adopting efficient pump types or impellers.

[0048] 3. Timely maintenance. The pump performance deteriorates and the efficiency decreases as the gap between the impeller and the guard plate increases. Therefore, the impeller should be adjusted forward in time to maintain a certain gap so that the pump can continue to work at high efficiency. When the pump wears out and cannot meet the system requirements, the wearing parts should be replaced.

[0049] The gap between the impeller and the front guard plate of the metal liner pump is between 0.5 and 1 mm. When adjusting the impeller clearance, first stop the pump, loosen the bolts that tighten the bearing assembly, tighten the nut on the adjusting bolt, move the oil bearing assembly forward, and at the same time turn the shaft by hand in the direction of pump rotation until the impeller and the front guard plate rub against each other. At this time, there is no gap between the impeller and the front guard plate, and then adjust it backward so that the gap between the impeller and the front guard plate is between 0.5 and 1 mm.

[0050] When the pulley slips, the operator can turn the limit handle 62 to drive the adjusting rod 61 to rotate. As the adjusting rod 61 rotates (because the upper half of the adjusting rod 61 is threadedly connected to the transmission box 53 through the threaded section), the adjusting rod 61 moves up or down. At this time, the adjusting rod 61 idles in the adjusting seat 60 and drives the adjusting seat 60 to move up and down, thereby driving the output pulley 57 to move up and down, so as to adjust the distance between the output pulley 57 and the input pulley 52. ​​During adjustment, the motor 59 moves up and down. After the adjustment is completed, the locking screw is set The nut 63 is used for positioning. As a further preference, locking nuts 63 are provided at the upper and lower ends of the top plate 53a of the transmission box body 53, so as to further improve the stability. As a preference, a guide column 73 can also be provided to further enhance the stability of the up and down movement of the motor 59. After the adjustment is completed, it can also be positioned by the limit nut 99, and according to the actual situation, gaskets of different thicknesses can be placed between the motor fixing seat 72 and the lifting frame 78 (placed according to the adjustment spacing), so as to further extend the stability and avoid the loosening of the transmission belt 58 due to the sliding of the motor.

[0051] As a further preference, when the transmission belt 58 needs to be replaced or overhauled and needs to be adjusted significantly, the screws used to fix the adjustment seat 60 and the mounting seat 56 are removed. At this time, the adjustment seat 60 is no longer in contact with the mounting seat 56, nor will they limit each other. Subsequently, the height of the lifting frame 78 can be adjusted by loosening each positioning nut 79 and then sliding the lifting frame 78 on the positioning screw 77. By adjusting the height of the lifting frame 78, the distance between the output pulley 57 and the input pulley 52 can be shortened, thereby facilitating the replacement of the transmission belt 58.

[0052] AH pump is a heavy-duty slurry pump. As this type of pump has thicker wear parts and is equipped with a heavy-duty bracket, it is suitable for conveying highly abrasive, high-concentration slurry or low-concentration high-lift slurry. Within the maximum allowable working pressure range of the pump, it can be used in multiple stages in series. This series of pumps can also be used for slurry with a certain degree of corrosiveness. The flow-through parts of AHR pump are made of rubber. Its pump body, pump cover and transmission parts are common to AH pumps. It is suitable for conveying fine particles and corrosive and abrasive slurry.

[0053] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
