test method
The ability of turbine oil, hydraulic oil, or lubricating oil to separate the air carried in is a key characteristic of its ability to stir and cause the diffusion of bubbles in the oil. To determine the performance of air release, the sample was heated to a specified test temperature and blown with compressed air. The time required for bubble separation is from the moment the airflow stops blowing until the volume of air sample carried into the oil decreases by 0.2%.
Complies with ASTM D3427, IP 313 and related standards
High precision temperature controller with digital settings and display digital control to guide users throughout the entire process
Automatically calculate the final sample density to determine the air release value. The overheat protection system ensures safe operation
Koehler's air release meter consists of a test container and an airflow control device, which is used to blow heating gas into a lubricating oil sample in a constant temperature state at a specified flow rate. The microprocessor control board guides users from beginning to end to perform density calculations and timed operations to measure the air release values of test samples. This system includes a drying oven for testing oil samples, with a temperature adjustable to 100 ℃; A circulating bath with a digital temperature controller and a hammer air bath; Air pump; Pressure gauge; thermometer. Heat resistant sample sleeves and baffles need to be selected. Windows software can be selected for automatic measurement.
