BN-040 Lubricating Oil Foam Characteristics Tester

Applicable standards: GB/T 12579 ASTM D892

The instrument consists of a high temperature bath (93.5 ° C), a low temperature bath (24 ° C) and a control device.

The high temperature bath (93.5 ° C) and the low temperature bath (24 ° C) main structure are basically the same, the cylinder bracket, heater, etc. are installed on the bath cover, and the installation is extremely convenient. High temperature bath

There is a heater and a heat shield (plexiglass). The low temperature bath is equipped with a cooling water pipe and a cold air pipe.

The controller uses the intelligent digital temperature display table PID parameter to control the bath temperature, and the control precision is high. Equipped with a constant temperature heater and an auxiliary heater for fast heating.

Gas flow control system: consists of gas filter dryer, steady pressure gas cylinder, rotor flow meter and so on. The desiccant is filled with a desiccant, and the change in color is observed to determine whether it is invalid. The gas is filtered and dried, and then divided into four channels by the gas cylinder, which are respectively connected to the flow nozzle of the flow meter, and are connected to the foam head connecting rod after being controlled by the flow meter.
