Further, the rotary spool is equipped with spool bore, and the spool guide sleeve is equipped with guide hole, the quantitative spool
Rotary spool is connect with spool guide sleeve after insertion guide hole and spool bore.
Further, one end of the shaft coupling has a convex block, and one end of the rotary spool is with one for convex block card
The card slot for entering and matching with convex block shape size.
Further, the pump housing is equipped with a groove far from that one end of rotation motor, and the guide sleeve limited block is caught in recessed
In slot, and the mode being connected by screw to fixes guide sleeve limited block with the pump housing；The rotary spool limited block is connected by screw
The mode and the pump housing connect is fixed far from that one end of rotation motor, and guide sleeve limited block is located at the inside of rotary spool limited block.
Using constant displacement pump provided by the present invention, the beneficial effect is that: in use, lubricating grease is injected from greasing head, rotation
Motor operations, shaft drives rotary spool rotation, because rotary spool is connect by a certain amount of spool with spool guide sleeve, energy
The output that lubricating grease is enough controlled by the rotation of rotary spool, so that lubricating grease can quantitatively flow into connector, then
It is quantitatively flowed into bearing by connector, it is quantitative accurate, be not in the situation that injection is excessive or injection is very few, improve note profit
The efficiency of consistent lubricant.

Specific embodiment
For it is relatively intuitive, be fully understood by technical solution of the present invention, now just combine attached drawing of the present invention to carry out non-limiting
Feature description it is as follows:
As shown in Figure 1-Figure 3, constant displacement pump, including the pump housing 1, the top and bottom of the pump housing 1 are respectively equipped with 2 He of fixing blocks for joints
Greasing head 3, fixing blocks for joints 2 are equipped with connector 4, and the pump housing 1 has mounting hole 1.1, has been caught in spool guide sleeve 5 in mounting hole 1.1,
Inserted with rotary spool 6 in spool guide sleeve 5, and rotary spool 6 is connect by a certain amount of spool 7 with spool guide sleeve 5, it further includes
One rotation motor 8, rotation motor 8 are fixedly connected with the cylinder body fixed block 18 that 1 one end of the pump housing is arranged in, the shaft of rotation motor 8
81 are connected with a shaft coupling 9, and one end of shaft coupling 9 is connect with one end of rotary spool 6；The other end of the pump housing 1 is equipped with guide sleeve
Limited block 10 and rotary spool limited block 11.
The pump housing 1 is equipped with a metering orifice 12, which extends to 1 bottom of the pump housing at the top of the pump housing 1, on greasing head 3
