The high and low temperature feeding room can be used to assess and determine the adaptability of electrical, electronic products or materials for storage and use in the environment where the product surface is subject to high temperature or low temperature. Widely used in aerospace products, information electronic instruments, materials, electrical, electronic products and other industries.
High and low temperature laboratory design standards:
<High and low temperature impact test chamber GB10592-89 standard>
<Constant temperature and humidity laboratory GB10586-89 standard>
<GB/T2423.1-2008 Environmental test of electrical and electronic products)
{GB/T2423.1-2001 High temperature test method)
(GB/ 2423.3-93 Test method for alternating damp heat)
Description of the overall structure of the high and low temperature laboratory:
Materials used: high-quality carbon steel plate for outer box, carbonized electrostatic spray
Union processing, inner box material SUS304 stainless steel high-quality light board
Insulation material: polyurethane rigid foam
We are sealed with double-chamber silicone rubber sealing material
Paper viewing window: It is a tempered insulating glass with conductive film of Mingyuan. In order to prevent the glass from frosting at low temperature, it is surrounded by a built-in special heating wire. It is also equipped with a lighting lamp for lighting for the current observation.
Box structure: There is a medium 50rm test hole with a dew on the back of the box. The plug material is a low-foaming silicone rubber strand, which can withstand high and low temperatures and has both thermal insulation performance.
Large-scale out-of-the-box test box control system for home use; imported programmable touch-change liquid product Chinese dialogue display, rice computer integrated controller.
Chamber body base: the beam is welded with 8# bad steel into a mesh frame, so that it can withstand the relocation of the chamber body and the personnel specimen under the horizontal system, without causing the bottom surface of the chamber body to be convex and uneven.
Pro, love 200kg/per square meter.
Chamber body: (The main body of the test honey (old body) is divided into six chambers and a double-opening chamber door, with a size of 1800 x 2000 mam, and the chamber body is made of high-quality stainless steel for the inner tank {to prevent prolonged exposure to humidity The inner wall is rusted in autumn), the outer tank is made of high-quality color steel plate, and the thermal insulation medium is polyurethane rigid foam insulation, which is light in weight and resistant to impact, and has good thermal insulation performance.
The door handle is open inside and outside, so that the test people can open the door freely from the closed room.
Protection system: the overall equipment is over-temperature, the overall equipment is under-phase/reverse-phase; the refrigeration system is overloaded, and the refrigeration system is over-pressured. The overall equipment is timed; it also has protections such as leakage, water shortage, running instructions, and automatic shutdown after fault alarm;
