Why is the oil inlet pipe of the compressor bearing thin, while the oil outlet pipe is thick?
Since there is pressure in the oil inlet pipe, as long as there is enough oil, using a too large diameter would be wasteful; the oil return line operates at atmospheric pressure, and to ensure smooth oil return, it is necessary for its diameter to be larger than that of the oil inlet pipe. :lol
The flow rate of the oil is very slow; if the pipes are of the same diameter, oil leakage is likely to occur, which will cause chaos at the site. Not only will cleaning be necessary, but a fine will also have to be paid
Agree with the view from the 2nd floor; the return oil is at atmospheric pressure
