ABSTRACT:
A cooling device for interior and exterior surfaces of a mud pump liner, in which one end of the suction tube3is connected to the water tank2, with the other end of the suction tube3connecting to the intake port of the spray pump4, and an end of the discharge pipe5is connected to the outlet port of the spray pump, with another end thereof connecting to the interior cooling nozzle1; and said another end of the discharge pipe5is also connected with a exterior cooling nozzle6, the spray port of the interior cooling nozzle1is placed inside the liner7, and the spray hole of the exterior cooling nozzle6is placed outside the liner7. The present invention additionally performs spraying against the outer surface of the liner and cooling it so as to sufficiently cool the liner/piston. In this way, the working temperature of the liner/piston is decreased and the service life thereof is extended. Experiments show that the working temperature of the liner/piston is decreased by at least 16° C., and service life thereof is at least doubled.
