Grease Lubrication Pump DDB-18

Grease lubrication pump with 18 ports named DDB-18, grease dispensing pump, it is the grease feeding source providing grease to each transportation piping to lubrication required points, the main parts of grease lubrication pump DDB-18 is electric motor, speed reducer, eccentric shaft , grease pressure parts.

Parts description of grease lubrication pump DDB-18:


The electric motor part. 1 drives the inner worn par. 2 by a rigid coupling in the drive gearbox, the worm drives the worm gear and worm shaft parts. 3 to rotate, and then the gear part. 4 and the gear part. 5 rotates accordingly by a rigid coupling connection and makes the gear part.6 to work as well.

Because the gear part. 6 and the eccentric shaft part.7 is coupled together by a pin part.8, so that the eccentric shaft part. 7 also rotate together along with gear part. 6. The eccentric disc part. 9 in addition to the rotation , but it also moves in planar motion , the inner piston of grease driven plate and driven disk is hinged together, therefore, the radial movement occurs periodically, so that the low-speed rotation of the motor is converted into reciprocation of the pistons radially. The connection of grease driven plate part. 11, grease stirring rod part. 12 and eccentric shaft part. 7 together and rotated with the eccentric shaft generates pressure to press grease to each injector.
