Engine cold and hot impact equipment

Abstract

The invention discloses engine cold and hot impact equipment, which comprises a heat preservation box body, a heating box body and an industrial refrigerating machine, wherein a stand column is installed at the bottom in the heat preservation box body through a bearing, a containing plate is fixed to the top of the stand column through bolts, and a driving motor is installed on one side of the stand column through an installation frame; an air inlet groove is formed in one end of the inner top of the heat preservation box body, a small suction fan is installed in the air inlet groove through the installation frame, an air outlet groove is formed in the other end of the inner top of the heat preservation box body, and a small air outlet fan is installed in the air outlet groove through theinstallation frame. Cold air is provided for the interior of the heat preservation box body through the industrial refrigerating machine, the temperature heated by the electric heating pipe is blown into the heat preservation box body through the fan, the cold air or hot air can circulate in the heat preservation box body, the engine can rotate during testing, the temperature rising and falling speed is high, the engine is heated and cooled evenly, and the equipment is suitable for being widely used and popularized.

Description

technical field [0001] The invention relates to the technical field of engine production, in particular to an engine cold and heat shock equipment. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc., such as internal combustion engines. Chemical energy is converted into mechanical energy. The engine is not only suitable for power generating devices, but also refers to the entire machine including the power device. The engine needs to undergo various tests during the production process, and the use of cold and heat shock equipment for cold resistance and high temperature resistance testing. An important part is to check whether the engine can work normally in a relatively cold or high temperature environment. [0003] Patent No. CN201820997...

AI Technical Summary

Problems solved by technology

[0004]The disadvantages of the above-mentioned thermal shock equipment are: 1. The overall structure is simple, the heating and cooling efficiency is low, and the engine cannot be effectively tested; The airflow and cold airflow are relatively calm after entering the insulation box, and the temperature cannot be quickly transferred to the engine, which reduces the test efficiency. Therefore, we propose a thermal shock equipment for the engine
