Embodiment
Below in conjunction with accompanying drawing, structural principle of the present invention and principle of work are described in further detail.
For a cooling means for fatigue tester, comprise the following steps:
1) tap water is input in water tank by the water inlet pipe of water tank bottom, detect the water temperature of low-temperature space in water tank by attemperating unit, when water temperature that attemperating unit detects low-temperature space lower than established temperature under in limited time, attemperating unit is closed water inlet pipe water inlet, when water temperature that attemperating unit detects low-temperature space higher than established temperature in limited time, attemperating unit is opened water inlet pipe water inlet;
2) water tank is connected with fatigue tester with circulation water inlet pipe by recycling outlet, with pump by the water input fatigue tester of water tank low-temperature space, to its cooling, high-temperature water enters water tank from recycling outlet, and the superfluous water in water tank enters water tank from the drainpipe of tank top;
Referring to Fig. 1,2,3, a kind of cooling device for fatigue tester, include water tank 2, the water inlet pipe 1 that passes through of water tank 2 is connected with water source, between water inlet pipe and water tank, be provided with attemperating unit 14, the temperature detector 6 of attemperating unit 14 is connected with water tank, the outer end of temperature detector 6 is connected with the magnetic material N utmost point 7, the N utmost point 7 is connected with the S utmost point 9 of magnet by spring 8, the S utmost point 9 of magnet is connected with water inlet pipe by connecting rod 10, connecting rod 10 is provided with water hole 12, and the sidewall of water tank 2 is also connected with fatigue tester 15 by recycling outlet 3, circulation water inlet pipe 4.
