Introduction to structural design
●This high and low temperature damp and heat test equipment uses high-quality materials and uses advanced processing equipment to process and shape the surface of the shell, which is then spray-coated to make it beautiful and smooth. The colors are coordinated and the lines are smooth and natural. The inner tank is designed as a closed space and is made of high-quality stainless steel plates.
The equipment shell is made of high-quality steel plate CNC machine tool processing. The surface of the shell is spray-painted to make it more smooth and beautiful
The inner tank is made of high-quality stainless steel plate
The insulation material is high-density glass fiber cotton to ensure thermal insulation performance and maintain indoor balance. Stable temperature
The observation window is made of multi-layer hollow tempered glass. The inner side of the glued sheet conductive film has the advantages of transparent heat insulation and is not prone to steam frosting.
The mixing system uses a long-axis fan motor with stainless steel multi-wings that is resistant to high and low temperatures. Type impeller to achieve strong convection and vertical diffusion circulation to make the temperature and humidity in the laboratory uniform and stable
Double-layer high-temperature-resistant high-tensile sealing strips are used between the door and the box of the equipment to ensure testing The area is sealed. The inner panel of the door is made of stainless steel and adopts a non-reaction door
The handle is easier to operate
The box is equipped with a sample display rack for customers to place test items
The test hole can Use external test power cord or signal line
The refrigeration system of the equipment is installed at the bottom. The compressor adopts Taikang brand imported from France to ensure the refrigeration effect and reliability
●High-quality fixed movable wheels installed at the bottom of the machine can be easily Conveniently move the machine to the designated position and finally fix the casters
The control part of the equipment is designed to be distributed on the right side of the equipment. There are temperature controller control switches, etc. It is easy to operate, simple and easy to maintain
●Humidification system Designed at the rear of the box to ensure reliable humidification effect.
Control system
Temperature and humidity controller adopts digital display instrument imported from South Korea
Direct digital display of temperature and humidity values and easy operation via key input
Accuracy and resolution
Temperature sensor platinum resistor Temperature and humidity sensor
Control method Thermal balance temperature and humidity adjustment method
Temperature and humidity control adopts system co-channel coordination control instrument
It has an automatic calculation function that can immediately correct the temperature and humidity changing conditions to make the temperature and humidity The control is more precise and stable
The return air outlet of this test chamber has an automatic defrosting device.
Heating and humidification system
●The heater uses a porcelain frame nickel-chromium wire electric heater. This heater has small thermal inertia
and has a long life. The controllable pulse duty cycle signal output by the instrument is controlled by the solid state relay to control smoothly and reliably.
●High-temperature completely independent system does not affect low-temperature damp heat test porcelain frame nickel-chromium wire electric heater
●Steam boiler electric heating and humidification method armored electric heating tube control method uses non-contact periodic pulse width modulation control device There is a water level control device and a heater anti-dry device
The temperature and humidity control adopts coordinated control of the same channel in the system
The output power of the temperature and humidity control is calculated by a microcomputer to achieve high-precision and high-efficiency power consumption.
In order to ensure the safe operation of the system, a protection system such as high-voltage control, overvoltage and overload must be installed in the system. At the same time, in order to monitor the operation of the system, a high-voltage meter must be installed at the high-voltage end to monitor the operation of the system.
