[Customer's Problem] Selection method and precautions for gear pump?
[Technical Solution] First, gear pump selection must be based on customer specific requirements.
Second, we must find out what the medium and viscosity of the gear pump are.
Third, how high is the temperature of the gear pump actually used.
Fourth, when the gear pump is actually used, it requires high working pressure, how long the actual pipeline is, how high the highest point is, and how many elbows are in the middle of the pipeline.
Fifth, according to the customer's actual pipeline conditions, a reasonable calculation of the actual pump resistance in the pipeline, the pipeline loss.
Sixth, the actual pumping medium of the gear pump has no corrosiveness, and the specific medium's PH value, and in actual use, the corrosiveness of the medium has no change with the temperature change.
Seventh, the medium pumped by the gear pump has no lubrication, contains particles or is easy to crystallize.
Eighth, whether the positive and negative phenomena exist in the use of the gear pump. If reverse oil pumping is sometimes used during use, it should be noted when ordering. Because the gear pump is equipped with a mechanical seal, it is forbidden to reverse the rotation, and if the conventional gear pump is used in reverse, the gear pump gear will fall off.
Ninth, when gear pumps need to work under high temperature conditions, they should be noted when ordering.
The above contents are all based on the problems encountered by customers in their actual work, for reference, if any problems, please communicate and correct.
