Ventilation regulated hot air supplied constant temperature oven |
摘要 |
A ventilation regulated hot air supplied constant temperature oven used for heat aging testing. Heated air of a predetermined temperature is supplied to a test oven body through an air supply port. Ventilation of the test oven is carried out through the air discharge port at a predetermined rate at predetermined time intervals. A discharge cylinder is provided at the discharge port, a blower is connected to the air supply port, a differential pressure detector is connected to the discharge cylinder and adapted to detect a differential pressure corresponding to the air flow rate on the basis of the data obtained in advance on the relation between a difference between the pressure at an outlet port of the blower and that at the discharge cylinder and the air flow rate, and a blower speed regulator is provided between the blower and the differential pressure detector and adapted to control the speed of the blower in accordance with an output level of a signal corresponding to a differential pressure measured by the differential pressure detector.
