Introduction to structural design
● This high and low temperature The test equipment uses high-quality materials and uses advanced processing equipment to process and shape the surface of the shell, which is spray-painted 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 and molding. The surface of the shell is spray-painted to make it smoother and more beautiful;
&#;The inner tank is made of high-quality stainless steel plate;
&#;Insulation Material: High-density fiberglass cotton ensures thermal insulation performance and maintains a balanced and stable indoor temperature;
&#; The observation window is made of multi-layer hollow tempered glass with a glued sheet-type conductive film on the inside, which is transparent, heat-insulating, and not prone to steam frosting, etc. Advantages;
&#;The stirring system uses a long-axis fan motor and a stainless steel multi-wing impeller that is resistant to high and low temperatures to achieve strong convection and vertical diffusion circulation to make the temperature in the laboratory uniform and stable
&#;Equipment Double-layer high-temperature-resistant high-tensile sealing strips are used between the door and the box to ensure the sealing of the test area. 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 silicone rubber seal Layer
&#;The test hole (left side of the machine) can be used for external test power cords or signal lines
(the hole diameter or number of holes can be according to customer instructions);
&#;Refrigeration of the equipment The system is installed at the bottom of the compressor and adopts Taikang brand imported from France to ensure refrigeration effect and reliability
&#;High-quality fixed movable wheels are installed at the bottom of the machine
The machine can be easily moved Go to the designated position and finally fix the casters to the test holes
&#;The control part of the equipment is designed to be distributed on the right side of the equipment with temperature controllers, control switches, etc., which are convenient to operate, simple and easy to maintain;
Control system
&#;The temperature controller adopts Fuji digital display temperature control instrument imported from Japan
Touch button. The system coordinates control with the same channel;
&#;Accuracy: .℃ (display range);
& #;Resolution: &;.℃;
&#;Temperature sensor: Platinum resistance tester
&#;Control method: Thermal balance temperature regulation method Japanese Fuji digital display temperature controller
&#;The automatic calculation function can reduce the inconvenience caused by manual setting.
The temperature control part of the equipment adopts intelligent high-precision digital display microcomputer control instrument for control. The membrane button touch setting, digital and direct display temperature control output power are all calculated by the microcomputer to achieve high precision and efficiency. Electricity benefits. Temperature control adopts . + . The coordinated control of the system on the same channel can improve the stability and life of the control components and interfaces. It has the function of automatic calculation to reduce the inconvenience caused by manual setting. If an error occurs during operation or setting of the device, a warning signal will be provided.
The time controller of the equipment controls the time required for the test and is easy to operate. When the equipment reaches the set time, it automatically stops the test and automatically enters the temperature equilibrium state.
Heating and humidification system
● The heater adopts porcelain frame nickel-chromium wire electric heater. This heater has small thermal inertia
and long life. The controllable pulse duty cycle signal output by the instrument is controlled smoothly and reliably through the porcelain frame nickel-chromium wire electric heater
solid-state relay.
&#;The high-temperature completely independent system does not affect the low-temperature test
&#;The temperature control adopts . Achieve high precision and high efficiency in electricity consumption.
&#;In order to ensure the safe operation of the system, high-voltage control, overpressure, overload and other protection systems need to 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.
Refrigeration system
&#;Compressor: fully enclosed French Taikang refrigeration compressor (group);
&#;Refrigeration method: mechanical refrigeration;
&#;Condensation method: Forced air cooling
&#;Refrigerant: R/R (environmentally friendly)
&#;All system pipelines are subject to ventilation and pressure leak detection tests
