walk-in cooler filter oil separator.
The following describes the structure of a filter oil separator in the walk-in cooler. At present, this kind of oil separator is often used in Freon walk-in cooler refrigeration system. When working, the high-pressure steam enters from the upper part of the air inlet, and is decelerated and filtered by the filter, and then discharged from the side air outlet. Part of the lubricating oil carried in the steam is separated and falls into the lower part of the cylinder. The oil return pipe of this oil separator is connected to the crankcase of the compressor. When the lubricating oil accumulated in the oil separator is enough to open the float valve, the lubricating oil is pressed into the crankcase of the compressor. When the oil level gradually drops to make the float drop to a certain position, the float valve closes. During normal operation, due to the intermittent operation of the float valve, the oil return pipe is cold and hot (the pipe is hot when the oil is returned, and the pipe is cold when the oil is stopped). If the oil return pipe has been cold or hot, it means that the float valve has failed and must be repaired. Manual oil return valve can be used for oil return operation during maintenance.
walk-in cooler oil collector
oil collector is a lubricating oil collection device, only used in ammonia walk-in cooler refrigeration system. Because ammonia and lubricating oil are incompatible, and lubricating oil is heavier than ammonia, it is easy to accumulate at the bottom of the container. In order not to affect the heat exchange effect of the heat exchanger, the lubricating oil must be regularly discharged from the oil separator, condenser, liquid reservoir and other containers. The function of the oil collector is to release the lubricating oil from the system under low pressure, which is safe and reliable without causing loss of refrigerant. In the system, the lubricating oil is separated and discharged most frequently, so the walk-in cooler oil collector is generally arranged near the oil separator.
