IEC60335砂尘试验箱

使用

This test chamber adopts artificial simulated dust environment, 测试设备测试样品防尘能力, 这里主要用在汽车低压电器上, 电气, 仪器, 米, 灯具粉尘模拟测试, 本设备的基本结构、原理及性能应满足低压电气保护国家标准GB4208-93关于砂尘试验技术要求.

结构特点

The outer shell of the equipment is made of cold-rolled steel plate with electrostatic spraying, and the inner shell is made of high-quality stainless steel plate. The overall appearance is beautiful and generous.There is a large area observation window and manual wiper device in the middle of the box door, which can facilitate to see the test condition of the specimen clearly during the test.The main control instrument of the equipment USES intelligent digital display control instrument, the main control instrument of the equipment USES intelligent digital display temperature control instrument, humanized design operation method, easy to learn and use, and different functional levels of instrument operation compatible with each other.Input using digital correction system, built-in common thermocouple and thermal resistance nonlinear correction table, accurate and stable measurement.Equipped with bit adjustment and AI artificial intelligence adjustment functions, 等级 0.2 准确性, a variety of alarm modes.The device has timing function.Heating equipment adopts stainless steel finned heating tube.The dust blowing cycle and vibration cycle of the whole equipment are adjustable and equipped with the timer of the general test.

A insulation layer is added between the stainless steel inner tank and the shell. The door of the test box is attached with an observation window. The lower part of the door is an electrical control area, and talc powder simulating sand and dust is placed in the hopper at the bottom of the test box.The talc powder is blown into the upper part of the work room through a net with 75 micron square holes by using a circulating fan and an automatic jarring device, so as to form a high-density dust fog in the test space for the test products.
