Feature
Type AH,HH,M Pump are cantilevered, horizontal, centrifugal slurry pump. They are made for the handing large density slurries in the metallurgical, mining , coal, power, building substance and other industrial section and so forth.
The body plates liner and impeller for variety AH,HH,M pumps have replaceable wear-resistant metallic liners or rubber liners.
The shaft seals for type AH,M, and HH Pump could be adoptable of gland seal , expeller seal or Mechanical seal .
The discharge branch can be positioned at intervals of forty five levels by ask for and oriented to any 8 positions to fit installations and programs.
CZPT assembly use cylindrical composition, which helps adjust the room in between impeller and protect plate liner very easily, and getting taken out entirely when being repaired. CZPTs use grease lubrication. Below are the push types, this kind of as V belt generate, gear reducer push, fluid coupling generate, and frequency conversion drive devices.
Wide functionality, great NPSH and large performance, the pump of this type may possibly be set up in multistage collection to meet the delivery for lengthy length.
Application
AH,HH,M pumps are using for handing powerful abrasive, high density slurries and reduced density, high head slurries in the metallurgical, mining, coal, electricity, creating material and other industrial departments etc.
For illustration: Coal washery processing, managing with the good ore and tailings in metal mine, handing merged bottom and fly ash in a thermal electricity station.

Possible Faults and Settlements
| Faults | Reason | Settlement |
| 1.Pump fails to discharge any h2o,The hand of strain gauge defeat violently | one.Suction pipe don’t have ample drinking water. 2.Suction pipe blocked or the valve is locked. |
one. Inject ample h2o 2.unlock the inlet valve,clear the blocks three.Exclude the air leakage |
| 2.The pump can not discharge water,the hand of vacuum meter conquer seriously. | one.The inlet valve is unlocked or silted up. 2.The resistance of suction pipe is also big or silted up. three.The top of suction is way too high. |
one.Unlock the valve or desilting two.boost the style of suction pipe or desilt three.Lower the top of the installation. |
| 3.The pump can not discharge h2o,strain gauge shows large strain. | one.The resistance of the discharge pipe is also large. 2.The impeller blocked three.The speed is gradual. |
1.Check out and alter the outlet pipe. 2.Obvious the impeller three. Improve the velocity. |
| four.The pump doesn’t rotate | The volute is silted up by the blocks. | Very clear the blocks |
| five.The potential is not enough | one.The blocks of the impeller or the inlet or outlet pipe. 2.The abrasion of the impeller is heavily. three.The pace is reduced to normal 4.Pump is mounted unreasonably or the leakage of the inlet pipe. 5.The transporting peak is also high,the loss of the resistance of the inside of pipe are way too massive. 6.The inlet valve not open adequate or blocked 7.The packing seal leaks |
1.Very clear the impeller or pipe. 2.Modify the impeller 3.Alter the velocity
|
| six.The motor of the pump is overloaded | one.The head of the pump exceeds the head of the doing work problem. 2.Not consider the slurry density when picking the pump. three.The packing press tightly |
one.Turn down the outlet valve,minimize the impeller or reduce the velocity. 2.Select the motor once again. 3.Alter the the screw of the packing gland |
| seven.Abnormal sound in the pump, and no water out | one.The resistance of the inlet pipe is also massive. two.The peak of the suction is way too higher. three.Cavitation occurred
|
|
| eight.pump vibrates | one.pump cavitate 2.The block of the impeller single vane 3.The no concentricity between the pump shaft and motor shaft four.Fasteners or foundation free |
1.Modify the h2o valve ,lower the top of the installation,reduce the resistance of the inlet. two.Clear the impeller 3.Alignment once again 4.Fasten the screw,and strengthen the basis. |
| 9.CZPT is overheat | 1.lock the cooling water 2.lubrication is not good. 3.the lubrication oil is not very clear four.the wrong path of the thrust bearing. 5.there is some thing improper with the bearing. |
|
| ten.Packing short life | The content of packing is not good | Adjust the packing |
| eleven.pump leak oil | 1.High oil stage 2.The rubber components invalid three.Assembly dilemma |
one.Reduce the oil amount two.Alter rubber spares three.Change the assembly |
| 12 Pump head leaking | one.The rubber parts not press properly | Assembly once more or press tightly |
