A kind of using method of electric heating constant temperature water bath with good stability

Abstract

The invention discloses an electric heating constant temperature water bath pot with good stability, which comprises a water bath box, a lifting mechanism, a water delivery mechanism and a cleaning mechanism; The bottom of the liner is connected with a drain pipe, an electric heating pipe is arranged between the left and right inner walls, a liquid level sensor and a temperature sensor are installed on the right inner wall, and the end of the drain pipe extends to the outside of the water bath tank. Solenoid valves are installed on the side, support bases are installed on the bottom array of the water bath box, fixed plates are fixed on the inner walls of the front and rear sides respectively, and the top of the fixed plates are connected with punching mesh plates by bolts, and the punching meshes The plate is located above the electric heating tube, and the water bath box is located on the right side of the installation groove. There is an electrical room; the electric heating constant temperature water bath has good stability, and can automatically remove the scale attached to the outer wall of the electric heating tube, improving the electric heating tube. heating efficiency.

Description

technical field [0001] The invention relates to the technical field of water baths, in particular to a method for using an electric heating constant temperature water bath with good stability.

[0002] The water bath is mainly used for distillation, drying, concentration, and warming of chemicals or biological products in the laboratory. It can also be used for constant temperature heating and other temperature experiments. , analysis room, an essential tool for education and scientific research, modern electric heating constant temperature water bath generally adopts a sink-type structure, which is a rectangular structure, the inner tank is made of high-quality stainless steel, and the outer shell is made of high-quality cold-rolled plate sprayed. The interlayer is insulated with glass wool, which can heat quickly and save electricity. There are electric heating tubes and brackets at the bottom of the inner tank, which are generally used to heat the liquid in test tubes and beakers at a constant temperature. Affected by dust and other factors, a layer of scale will adhere to the surface of the electric heating tube, resulting in low heating efficiency of the electric heating tube, which will lead to unstable temperature regulation function of the water bath, affecting the accuracy of the experimental results
