Ventilation aging testing machine

1
Execution standards:
This instrument is designed to meet the requirements of test standards.
Second purpose
Usage:
This machine is suitable for changing the characteristics of wires, leather, plastics, rubber and cloth before and after heating. In order to maintain fresh air in the box when wires are heated, the ventilation volume is specially adjusted. This testing machine is equipped with a precision-designed air displacement adjustment device and a digital voltmeter, ammeter, and watt-hour timer, which can be used to measure the air displacement rate. The horizontal forced air circulation system and the air flow adjustment plates on both sides of the interior ensure uniform and stable temperature inside the testing machine. This machine has passed the institutional inspection, and our company has become a qualified production factory

a set of rotary disk and rotary motor. (Detachable rotation speed of the rotary table~r)
The third layer is a high-temperature resistant electrolytic plate, the fourth layer is an air ventilation layer and a heating tube layer, and the fifth layer is a stainless steel plate.
Auxiliary equipment
Fuseless switch
Over-temperature protection
Indicator lights for various actions
A set of air ventilation volume measuring device. (Measure the air exchange rate of the aging furnace based on the power consumption, with a digital wattmeter and digital R attached)
A set of air exchange volume adjustment devices. The air exchange rate is adjustable from times to times/hour, measured at ℃.
Wide angle projection lighting equipment.
Equipped with a set of timers: used for aging timing and ventilation volume measurement timing.
Multi-layer vacuum glass windows.
A shelf for storage in the laboratory.
A watt hour watch made in Taiwan.
Equipped with four locking casters.
Air supply circulation system:
Use multi-wing centrifugal circulation fan: one air blower
Use forced air ventilation, the air exchange volume can be up to times/hour, measured at a temperature of ℃.
Circuit control system:
The temperature controller adopts microcomputer electronic setting and digital display (made in Taiwan)
This system adopts RR+RR+R+R control
(i.e. Proportional integral differential + R), which can improve the service life and stability of the control component interface.
With automatic calculation function, no manual setting is required.
Using high-precision filament sensors.
The relay is a Japanese R brand
The timer is a Taiwanese brand
The two motors are made in Taiwan
The air exchange rate is obtained by using the Japanese standard formula
Equivalent to the number of air exchanges per hour. : Power consumption during ventilation.
: No power consumption during ventilation.
: The total volume inside the aging furnace
: The density of the air around the aging furnace (/): The temperature difference between the inside and outside of the aging furnace.
The whole machine runs an aging test on an hourly basis before leaving the factory
