Claims

[Scope of utility model registration request]

(1) In a testing machine that measures corrosive wear when a material to be tested, such as metal, is subjected to friction in a corrosive atmosphere, the material to be tested is placed in a sealed insulated container with a corrosive gas inlet and outlet. Test conditions in which a testing machine is constructed by attaching a sliding motor for sliding contact and wear on the surface, and heating means equipped with a heating heater, and the number of tests is set in the front stage of the power supply circuit as the circuit means of the testing machine. A temperature control circuit that provides a setting circuit and independently controls multiple heaters at a later stage;
A control circuit for a sliding motor constituted by an induction motor whose speed can be variably adjusted by a speed adjustment means is provided, and an abnormality detection circuit is further provided for detecting an abnormality based on detected values from the heater and the sliding motor. ,
A control device for a corrosion and wear tester, characterized in that a cutoff circuit is provided to cut off a power supply circuit based on the output of the abnormality detection circuit.

(2) The control device for a corrosion and wear tester according to claim 1, wherein the test condition setting circuit is a counter that allows the number of tests to be set externally.

(3) The abnormality detection circuit includes an overload detector that detects an overload state of the induction motor, and an overheat detector that detects an overheating state of the temperature atmosphere via a thermocouple. Featured utility model registration claim No. (1)
A control device for a corrosion abrasion tester according to item (2) or item (2).
