Question

1. Describe the general characteristic of this pump series including pumpingmechanism type, housing material, bearing type, etc..

Answer 1

ANSWER:

the given pump information represents to the displacement pumps.

for this kind of pump the stream is around steady with expanding pressure yet lessens somewhat because of higher leakages at higher pressures

the stream rate is roughly proportional to rotational speed and relocation (in^3 or cc/rev)

commonly the pumping mechanism can be one of the accompanying.

1) swash plate pumps with hub cylinders

2) twisted hub cylinder pumps

3) internal gear pumps

4) spiral cylinder pumps with erratic cam ring

5) spiral cylinder pumps with flighty shaft

6) outer apparatus pumps

7) screw pumps

8) vane pumps

9) others

Normally the housing materials are   

1) throwing combination/treated steel

2) shaft-combination/treated steel

3) interenals (gears,pistons,etc) combination/treated steel

regularly bearing composes are

1) for bent axis and axial piston pumps, taper rolling bearings

2) pivotal roller push(thrust) bearings for swash plate pumps with axial cylinders.

etc.
