), and from the clean tank (7), centrifuge afi (6
), a circuit consisting of a heater (8), a pump (9), and a filtration device (1o) is formed to remove sludge, and the lubricating oil in the clean tank (7) is transferred to the supply tank (3).
). Such two processes of centrifugation and filtration
Although we were able to clean the lubricating oil to a considerable extent by using two methods, there were only three slags that could be removed by the darning method.
The size of the sludge is limited to ~5μ, and sludge finer than this cannot be removed, so it has not been possible to keep the content of insoluble matter in the oil low. In addition, if the lubricating oil in the supply tank is poured directly into the filtration device without using a clean tank separate from the supply tank, the filtration device will quickly become clogged with coarse sludge, so a separate clean tank is required. was required to be used.

A cleaning circuit consisting of a heater, a three-way switching valve, a sludge accumulation device, and a centrifugal separator is installed. First, the sludge accumulation device is bypassed by switching the three-way switching valve, and coarse sludge in the oil is centrifuged using only the centrifuge. By switching the three-way switching valve, the fine colloidal sludge in the oil is collected and coarsened by the sludge accumulator, which is then separated and removed by the centrifuge, and at the same time, the pressure regulating valve is used to collect 0.5 kg/kg of sludge in the circuit.
It is characterized by being maintained at a low pressure of about cx2.
