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.

Note Of Grease Pump DDB-18 Before Operation:

  1. The multi-point lubrication grease pump DDB-18 should be installed in a place where the ambient temperature is suitable for working operation and small dust, which is convenient for oil or grease filling, adjustment, inspection and maintenance.
  2. The HL-20 gear oil must be added to the gear box to the oil level specified level.
  3. To add grease to pump reservoir the of the DDB-18 grease pump, the SJB-D60 manual fuel pump or the DJB-200 electric grease filling pump must be used to fill the grease to the pump reservoir of the DDB-18 grease pump. It is strictly forbidden to start the motor when there is no grease or oil in the reservoir.
  4. According to the arrow direction of rotation on the cover of the electric motor, the motor should be connected with stable wire and not reversed.
  5. The accuracy of the filter screen is not less than 0.2mm and should be cleaned regularly.
  6. The grease pump DDB-18 should be kept clean at all times. It is strictly forbidden to remove the reservoir cover, to prevent dirt from entering the pump chamber and affecting normal work.
