Gear again on crankshaft large ring gear meshing band dynamic crankshaft rotate.This power transmission mode is essentially two-stage transmission, function
Rate loss is bigger than normal, structure also slightly complicated.
For three cylinder single-action reciprocating piston pumps, since there is 120 ° of phase angles between three cranks, therefore
There is relatively large vibrations during operation for this slush pump.Further, since the limitation of separate unit mud pumpage, in drilling well
When need 2 pump even 3 pump parallel operations.

The two sides main wall plate of slush pump host is stretched out in shaft end respectively, is connected with the axle sleeve of permanent magnet machine rotor；The two of slush pump host
It is respectively welded a flange outside the main wall plate of side, permanent magnet motor stator is mounted on flange.
Preferably, the crankshaft includes three cranks for being mutually 120 °, and each crank passes through connecting rod bottom-end bearing and connecting rod
One end be connected, two connecting rods are connected on each crank, the other end of connecting rod is matched with the outer ring of small end bearing,
The inner ring of small end bearing is mounted in the inner cavity of crosshead by crosshead pin shaft, and the two sides up and down of crosshead are respectively set
There are upper guide plate and bottom guide, crosshead is connected with the piston cylinder in fluid end.
It preferably, include at least three piston cylinders in every group of fluid end of the slush pump host.
The working process of the utility model is as follows:
Start magneto, the rotor of magneto drives crank rotation, is mounted on the connecting rod on crankshaft crank by ten
Prefix moves reciprocatingly between upper guide plate and bottom guide, and then drives the piston action in fluid end, and slush pump starts drilling
Operation.
The utility model has the following beneficial effects:
Permanent magnet machine rotor is connected to the shaft end of crankshaft in slush pump host by the utility model, and permanent magnet motor stator is led to
It crosses flange to be fixed on the outside of the two sides main wall plate of slush pump host, magneto directly drives crank rotation, simplifies transmission knot
