Laboratory quenching tank

Abstract

The invention discloses a laboratory quenching tank. The laboratory quenching tank comprises a control cabinet and a quenching tank welded by a steel plate, wherein a water drainage pump is arranged in the quenching tank, a water drainage pipe is arranged in an outlet of the water drainage pump, a water inlet is formed in the side wall of the quenching tank, a water inlet pipe is arranged at the water inlet, an electromagnetic valve is arranged on the water inlet pipe, a water level upper limit detection probe and a water level lower limit detection probe are arranged on the side wall of the quenching tank, a temperature probe is arranged in the quenching tank, the water drainage pump is electrically connected with the control cabinet, the temperature probe, the water level upper limit detection probe and the water level lower limit detection probe are in signal connection with the control cabinet, and the water drainage pump, the temperature probe, the water level upper limit detection probe, the water level lower limit detection probe (11) and the electromagnetic valve form a temperature and water level automatic control loop. Compared with the prior art, a quenching liquid valveis automatically opened to add an external storage medium to regulate the temperature in the preferential scheme, and the quenching uniformity of a workpiece is guaranteed.

Description

technical field [0001] The invention relates to a quenching tank, in particular to a laboratory quenching tank, which can meet the requirements of workpieces for different quenching media and quenching temperatures. Background technique [0002] At present, laboratories use simple quenching tanks to do quenching tests. It is relatively easy to do when the workpiece is small, and it becomes more troublesome with the prolongation of quenching time for slightly larger workpieces. Either the medium temperature is not easy to control or it cannot be uniformly quenched; It is difficult to achieve the purpose of quenching experiment. Therefore, designing a laboratory quenching tank that can meet the requirements of workpieces for different quenching media and quenching temperatures is a technical problem that needs to be solved at present. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a laboratory quenching tank that can mee...
