Metallographic phase polishing solution automatic feeding machine
2013
The invention provides a metallographic phase polishing solution automatic feeding machine which is used for grinding and polishing of metallographic specimens. The metallographic phase polishing solution automatic feeding machine is formed by a stirring motor, a liquid storage cylinder, a stirring shaft, blades, a liquid pump motor, a plunger liquid pump, check valves, connecting ducts, a nozzle and a single-chip microcomputer. The metallographic phase polishing solution automatic feeding machine is characterized in that the stirring motor is installed on the upper portion of the liquid storage cylinder, the output end of the stirring motor is connected with the stirring shaft, the blades are installed at the lower end of the stirring shaft, the output end of the liquid pump motor is connected with a cam, the cam is connected with the piston of the plunger liquid pump, the cylinder block of the plunger liquid pump is connected with the liquid storage cylinder and a liquid outlet end nozzle respectively through the ducts, and check valves are respectively arranged on the ducts at two ends of the plunger liquid pump to control liquid to flow only along a single direction. The metallographic phase polishing solution automatic feeding machine has the advantages of being accurate in liquid outlet quantity, capable of setting liquid outlet time intervals, high in degree of automation, and capable of achieving the switching usage between an automatic function and a manual function according to different operation requirements.
