The Fully automatic small mobile quenching water tank,water quenching tank,quenching tank,water hardening tank,automatic water quenching tank is made of thick steel plate or stainless steel with a square structure. The quenching water tank is equipped with an electric heating tube, and the quenching water tank is equipped with a high-power circulation pump, air-cooled heat exchanger, automatic liquid level control and automatic constant temperature Control cabinet. Its working principle is: when the workpiece enters the water and is quenched, when the water temperature rises to the set temperature, the circulation pump starts to work, the heat is removed by the heat fins of the heat exchanger to achieve mutual heat exchange, and then return to the water in the quenching tank The temperature decreases, and after circulating heat exchange, the water temperature in the quenching tank will be significantly reduced. When the water temperature is lower than the set heating temperature, the automatic constant temperature control cabinet will control the heating tube to heat the quenching water medium in the quenching water tank, so that the quenching water temperature is constant within the process quenching temperature. You can set automatic water intake, make up water, limit the water level, safe and convenient. When the weight of the quenched workpiece is large, an automatic lifting mechanism is selected to reduce labor intensity and provide work efficiency.
