AI Technical Summary

Technical Problem

The push rod of the mechanical temperature controller in the prior art is not pushed evenly by the liquid, which causes the transformer pointer to display inaccurately.

Method used

A mechanical driving structure of the temperature controller is designed, including a driving cylinder, a bellows, a driving assembly and an expansion medium. Through the thermal expansion and contraction principle of the expansion medium, combined with elastic parts and limit holes, the driving rod is ensured to move linearly in a fixed direction to push the pointer structure.

Benefits of technology

The uniform movement of the push rod is achieved, the accuracy of the pointer display is ensured, the problem of non-linear and non-uniform liquid pushing of the push rod in the mechanical temperature controller is solved, and the accuracy of transformer temperature control is improved.

Abstract

The mechanical pushing structure of the temperature controller comprises a pushing cylinder body and a cylinder cover, one end of the pushing cylinder body is sealed, the other end of the pushing cylinder body is open, a liquid injection hole is formed in the end face of the sealed end of the pushing cylinder body, and the cylinder cover seals and covers the open end of the pushing cylinder body. A limiting through hole is formed in the cylinder cover; the corrugated pipe is arranged in the pushing cylinder body, and one end of the corrugated pipe is connected with the cylinder cover; the pushing assembly comprises a base, an elastic part and a pushing rod, the base is connected with the other end of the corrugated pipe, a closed cavity is defined by the base, the corrugated pipe, the cylinder cover and the pushing cylinder body, one end of the pushing rod is fixed to the base, and the other end of the pushing rod penetrates through the limiting through hole; the expansion medium is injected into the closed cavity through the liquid injection hole; according to the utility model, the problem of inaccurate display of the pointer of the transformer caused by non-linear and non-uniform hydraulic pushing of the push rod of the mechanical temperature controller in the prior art is solved.
