In many current chemical experiments, the vacuum coating high and low temperature circulation system can be used, making the high and low temperature refrigeration heating system supporting the vacuum coating system, and the operation is more efficient.

The vacuum coating high and low temperature circulation system has a plurality of electric heating sleeves and a stove opening, and a plurality of heating control buttons are respectively arranged on the casing, and one heating temperature sensor is arranged on one side of each cooking stove, and each heating temperature sensor is combined with one The heating temperature display device is electrically connected, and the heating temperature display device is disposed on the housing. Vacuum coating high and low temperature circulation system The bottom of the electric heating sleeve is provided with a spring that can be extended up and down. The bottom end of the spring is fixed to a horizontal plate in the housing, and the spring is provided with a guiding cylinder, and the guiding cylinder is fixed in the housing, and is reflowed. Corresponding to the upper part of the bottle, an end point sensor for detecting the liquid level in the reflow bottle is arranged on the casing, and the end point sensor is connected with the main control circuit through the end point automatic control switch of the reflow bottle to control the electric heating sleeve.

The main control circuit includes a timing unit that controls shutdown by a preset working time, and a time display is set on the housing. A cooling pipe is arranged in the cold water tank, and the cooling pipe is connected with the compressor, and a water level gauge corresponding to the cold water tank is arranged on one side of the casing. A cooling temperature sensor is disposed in the cold water tank, and the cooling temperature sensor is electrically connected to the cooling temperature display device, and the cooling temperature display device is disposed on the casing. The water inlet of the condensing bottle is arranged in the upper part of the bottle body, the water outlet is arranged in the lower part of the bottle body, the condensation tube is spirally shaped; the bottom of the bottle body is provided with a bottle mouth, and a vacuum is provided between the bottle mouth and the inner cavity of the bottle body. a chamber; the mouth of the bottle is in sealing communication with the mouth of the retort, and the mouth of the condensing bottle is connected with a steam pipe; the inlet of the condensing pipe is located at the upper part of the bottle of the condensing bottle and extends out of the body of the bottle; The mouth is connected to the upper part of the steam pipe. A gas supply pipe is arranged in the steam pipe, and the bottom end of the liquid pipe is connected with the bottle mouth of the condensing bottle, the port of the liquid pipe extends out of the steam pipe, and a sealing plug is arranged on the pipe mouth; the port of the steam pipe is added The outer wall of the liquid pipe is sealed.

The setting of the vacuum coating high and low temperature circulation system is set by the professional technicians of Wuxi Guanya LNEYA. If you have any questions, you can contact the relevant technical personnel.
