With the temperature of reduction lubricating oil.
The operation principle of a kind of engine lubricating oil supply pressure regulation and attemperating unit is as follows：
Engine lubricating oil after the extraction of circulating pump 1, it is pressurized after be supplied to the oil-in of oil water heat exchange device 8, lubricating oil
After flowing out from the oil export of oil water heat exchange device 8, the entrance (i.e. A mouths in Fig. 5) of the second ratio adjusting valve 5 is flow to, and from the second ratio
The first outlet (i.e. B mouths in Fig. 5) of example regulating valve 5, second outlet (i.e. C mouths in Fig. 5) flow out；The lubricating oil that first outlet flows out
When flowing through pressure sensor 6, pressure sensor 6 will detect that the pressure of current lubricating oil；When the pressure that pressure sensor 6 is detected
When power is higher than engine desirable pressure, the aperture of the proportion adjustment first outlet of the second ratio adjusting valve 5 and second outlet so that the
One outlet aperture ratio reduces, the aperture ratio increase of second outlet, realizes that the lubricating oil ratio flowed through at pressure sensor 6 subtracts
It is little, until dropping to the pressure needed for engine；When the pressure that pressure sensor 6 is detected is less than engine desirable pressure,
The aperture of the proportion adjustment first outlet of the second ratio adjusting valve 5 and second outlet so that first outlet aperture ratio increases, second
The aperture ratio of outlet reduces, and realization flows through the lubricating oil ratio increase at pressure sensor 6, until rising to needed for engine
Pressure；When lubricating oil flows through temperature sensor 7, temperature sensor 7 will detect that the temperature of current lubricating oil；Work as TEMP
The temperature that device 7 is detected higher than engine it is temperature required when, the first ratio adjusting valve 9 adjust in the presence of controller its first
Outlet (i.e. M mouths in Fig. 5) and the aperture of second outlet (i.e. N mouths in Fig. 5) so that first outlet aperture ratio increases, and second goes out
The opening ratio of mouth reduces, and now, the cooling water of testing equipment is flowed through by the entrance (i.e. L mouths in Fig. 5) of the first ratio adjusting valve 9
The flow meeting ratio increase of first outlet, meanwhile, cooling water is flowed at the water inlet of oil water heat exchange device 8 after first outlet
Flow can ratio increase, oil water heat exchange device 8 exchanged heat ratio increase so that the temperature drop of lubricating oil, until
Drop to the temperature needed for engine；When the temperature that temperature sensor 7 is detected is temperature required less than engine, the first ratio
The aperture of the proportion adjustment first outlet of regulating valve 9 and second outlet so that first outlet aperture ratio reduces, second outlet is opened
Than increase, now, the cooling water of testing equipment can be compared degree by the flow that the entrance of the first ratio adjusting valve 9 flows through first outlet
Example reduces, meanwhile, cooling water is flowed into the flow meeting ratio at the water side-entrance of oil water heat exchange device 8 and is reduced after first outlet,
The heat ratio for being exchanged of oil water heat exchange device 8 reduces so that the temperature of lubricating oil is raised, until rising to needed for engine
Temperature；Finally, the lubricating oil for regulating pressure and temperature is delivered to engine by this device by pipeline road, realizes that circulation makes
