Description

Solar thermal insulation bucket liner CNC testing machine

technical field

The utility model relates to a pressure test device for the inner tank of a solar thermal insulation bucket, in particular to a numerically controlled pressure test machine for the inner tank of a solar thermal insulation bucket.

technical background

At present, the air tightness test of the inner tank of the solar thermal insulation barrel basically implements the traditional pressure test air pump pressure test, and the work of the pressure test air pump is controlled by manually operating the power switch of the air pump. Due to manual operation, the pressure value is difficult to accurately control, resulting in detection performance. Unstable, there is often a certain error between the set pressure value and the product quality is likely to be unstable, causing serious quality defects; and the manual connection of the pressure test air plug to tighten and disassemble is time-consuming and laborious, and the production efficiency is low. Strong.

Contents of the invention

The purpose of this utility model is to provide a fully automatic solar heat preservation barrel inner tank numerical control pressure test machine with reasonable design, compact structure, high test accuracy, convenient use and stable performance in view of the above shortcomings and deficiencies.

The technical scheme adopted by the utility model to solve the technical problem is: a kind of solar thermal insulation bucket liner numerical control pressure test machine, which consists of a metal bracket, a water tank, a fixed bracket for the movable water tank liner, a cylinder, an electric contact pressure gauge, a time relay, A system composed of digital display time relay, intake pipe, air plug, pressure gauge and switch. Fix the water tank on the lower part of the metal bracket and fill water to the scale line, set the pressure and time parameters required for the pressure test on the electric contact pressure gauge, time relay, and digital display time relay respectively, and fix the inner tank of the heat preservation bucket in the middle. On the bracket, a group of cylinders press the air plug into the heat collecting pipe hole of the water tank liner to make the water tank liner completely sealed, the air intake pipe is connected to the water inlet and outlet pipes of the water tank liner, and when the switch is turned on, the air is automatically inflated to the pressure value. Another group of cylinders automatically presses the fixed bracket of the movable water tank liner into the water tank to check the air tightness of the water tank liner. After the test, the system will automatically exhaust and return to its original position.

Compared with the existing pressure testing technology, the numerical control pressure test machine for the inner tank of the solar thermal insulation barrel of the utility model has the characteristics of reasonable design, simple structure and convenient use. Efficiency, reduce labor intensity and other advantages. At the same time, because the pressure and time of the air tightness test are completely controlled by digital, it avoids the difficulty of accurately controlling the pressure value, resulting in unstable detection performance, and the error between the set pressure value, which ensures the stable quality of the product and makes the product The qualified rate reaches 99.99%.
