High head high chrome slurry pumps

High head high chrome Wet End Parts slurry pumps made in Shijiazhuang Naipu Pump Co.,ltd

High head slurry pumps is one type of centrifugal slurry pumps, which is used for copper mining, silver mining,gold mining, coal mining ect. 

High head centrifugal slurry pumps is horizontal type, drived by motor or diesel engine.

AH, HH Pump for cantilever, horizontal Centrifugal Slurry Pump.It is suitable for conveying strong abrasion and high concentration slag slurry to metallurgy, mining, coal, electric power, building materials and other industrial sectors.This type of pump can also be used in series.

AH, HH type pump shaft seal can be used packing seal or centrifugal seal.The outlet position of the pump can be installed and used by rotating eight different angles according to the need according to the 45 degree Angle interval.

Model meaning:

For example: 10/8st -- AH (or HH)

10 -- pump inlet diameter

8 -- diameter of pump outlet

HH -- high lift Slurry Pump

AH - the slurry pump

ST -- bracket type

Repair and maintenance of AH type slurry pump

Ding yi pump is durable, as long as the assembly and installation is reasonable, hebei ding yi pump manufacturing co., LTD. Ah Slurry Pump can show the advantages of reliability, long life and less maintenance.

(a) shaft seal maintenance

Packing seal pump to regularly test the seal water flow and pressure, to always keep a small amount of clean water along the shaft flow, the method is to regularly adjust the packing gland, if the packing can no longer be used, should be all replaced.

The impeller seal pump USES the oil cup to fill oil, is more economical, but must lubricate the seal chamber regularly, the rubber relief cover does not need lubrication (some pumps exception).

(b) the performance of the regulating impeller deteriorates with the increase of the clearance between the open impeller and the suction side guard plate. This effect is not significant for the enclosed impeller pump, but there are exceptions.

As a result of wear, clearance increases, the efficiency of the pump decreases, so, in order to maintain the pump rotation, the impeller must be timely to move forward (see pump assembly: impeller clearance adjustment) this adjustment takes only a few minutes and does not need to remove any parts.

After adjustment, before starting again, check whether the impeller rotates normally and whether the bearing box fastening bolts are tightened.

(c) bearing lubrication

When the Bearing Assembly is properly assembled and lubricated with grease in advance (see bearing assembly), and the shaft is installed into the bearing box, the bearing assembly is not only reliable in use but also has a long life, as long as there is no water or other external intrusion and timely maintenance.

Maintenance personnel shall regularly (not more than 12 months apart) disassemble the bearing box, observe the bearing and grease, and then determine the time for the next inspection.

The number of times regularly lubricated and the amount of grease injected depend on a number of factors and their interactions, including speed, bearing specifications, continuous operating time, ratio of pump stop-start time, operating environment such as cycle and operating temperature, spatter, contamination or the presence of impurities.

Most bearing pump running speed is low, but also has the risk of damage, ding yi pump manufacturing co., LTD. In hebei AH type slurry pump its reason mainly is the excessive lubrication bearing, but avoid excessive lubrication precautions and not to the bearing maintenance, so lubrication experience and judge ability is determine the determinants of lubrication program, the better way is in the early stages of the operation, constantly observe bearing, carefully record unusual situation, for example, the temperature and purity.
