diesel engine driven centrifugal pump

Product introduction

The 2 / 1.5 B - AH Heavy Duty Centrifugal Slurry Pump High Chrome Metal Slurry Pump is a horizontal, vertical open, double pump housing construction with a replaceable metal lining or rubber lining for the pump body and pump cover. The lining can be used for wear through. Up to now, there is no need to replace, extend the maintenance cycle and reduce operating costs.

The 2 / 1.5 B - AH Heavy Duty Centrifugal Slurry Pump High Chrome Metal Slurry Pump is suitable for the transport of abrasive or corrosive slurries and is widely used in metallurgy, mining, petroleum, chemical, coal, electricity, transportation, river dredging, building materials and municipal engineering.

Specifications

Centrifugal slurry pump working principle:

1. Before the pump works, the staff must first inject the liquid used for conveying into the pipeline and the pump casing, and fill the two;

2. When the slurry pump is started, the liquid in the impeller will be rotated by the blades of the impeller;

3. Under the action of centrifugal force, the liquid rotates forward and then flows out of the impeller;

4. During the process of flowing the liquid from the impeller inlet to the impeller outlet, the velocity energy and the pressure energy are increased due to the energy conversion, and the liquid flowing out from the impeller is discharged through the pump casing flow passage and then discharged from the discharge pipe;

5. At this time, the impeller inlet is formed by the discharge of water, and the liquid in the suction surface is pressed into the water inlet of the impeller under the action of atmospheric pressure;

6. The rotating impeller continuously draws in and drains water to form a continuous stream of water.

AH slurry pump start: Check the entire unit as follows before starting.

(1) The pump should be placed on a firm foundation to withstand the full weight of the pump to eliminate vibration and tighten all anchor bolts.

(2) Pipes and valves should be supported separately. There should be a gasket at the pump flange. When tightening the coupling bolt, please pay attention to the metal lining of the pump is higher than the flange. At this time, the bolt should not be tightened too much to avoid damage to the gasket.

(3) Rotate the shaft by hand according to the direction of rotation of the pump. The shaft should be able to drive the impeller to rotate and there should be no friction. Otherwise, the impeller clearance should be adjusted.

(4) Check the steering of the motor. Make sure that the pump rotates in the direction of the arrow marked on the pump body. Note that the pump is not allowed to rotate in the opposite direction, otherwise the impeller thread will trip, causing damage to the pump.

(5) When the transmission is directly connected, the pump shaft and the motor shaft should be accurately centered. When the belt is driven, the pump shaft and the motor shaft should be parallel, and the position of the sheave should be adjusted so as to be perpendicular to the groove to avoid severe vibration and wear.

(6) A detachable short pipe shall be installed at the suction pipe of the pump. The length shall be sufficient to disassemble the pump cover and replace the consumable parts, so as to facilitate the inspection of the pump. The length of each pump is shown in the external dimensions of each pump.

(7) Shaft seal inspection: The pump of the auxiliary impeller shaft seal has different sealing structure. Therefore, when the oil pressure cup is equipped with oil cup, it is necessary to add grease through the oil cup. The grease is recommended to be lubricated with calcium and sodium. fat.
