Auxiliary oil pump is connected with oil strainer；Lubricating oil is filtered by oil strainer.
The temperature-sensing valve connected between the oil strainer, the oil inlet of air blower gear-box and oil cooler three.The temperature control
Valve is three-way temperature control valve；The arrival end of oil strainer is connected with temperature-sensing valve A mouths；Temperature-sensing valve B mouths and air blower gear-box oil-feed port
Connection；The oil inlet of temperature-sensing valve C mouths and oil cooler connects, and oil-out and the air blower gear-box oil-feed port of oil cooler connect
Connect.
Thus, according to current lubricating oil temperature, its stream is controlled to flow to by temperature-sensing valve；When lubricating oil temperature is not higher than using temperature
When spending, lubricating oil is controlled to flow directly into air blower gear-box oil-feed port by temperature-sensing valve；Otherwise, lubrication oil is controlled by temperature-sensing valve
Stream, is partly into air blower gear-box oil-feed port；Another part enters drum after the C mouths of temperature-sensing valve enter oil cooler cooling
Gear case of blower oil-feed port.
The utility model has the advantage of：
(1) the utility model unit high-speed centrifugal blower lubricating oil temperature control system, simple in construction, control is accurate,
Cost is relatively low.
(2) the utility model unit high-speed centrifugal blower lubricating oil temperature control system, using temperature control valve arrangement, machine is belonged to
Tool structure, it is more stable compared to electric-control system, reliable.
(3) the utility model unit high-speed centrifugal blower lubricating oil temperature control system, automatically controlled system is avoided in principle
The component loss of the switch valve repeatedly of system, oil temperature is controlled using the principle of shunting cooling.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The utility model unit high-speed centrifugal blower lubricating oil temperature control system, as shown in figure 1, including main oil pump 1,
Oil cooler 2, auxiliary oil pump 3, oil strainer 4 and temperature-sensing valve 5, as shown in Figure 1.
The main oil pump 1 is main engine driven pump, is installed on the output shaft of air blower gear-box 7, by air blower gear-box 7
Gear transmission power, it is the fuel feeding of air blower gear-box 7 in the continuous service of air blower 6.The auxiliary oil pump 2 is electrodynamic pump, installation
In in air blower petrol station 8, it is connected between air blower petrol station 8 by flange, for before starting shooting and before initial, shutdown of starting shooting and shutting down
The fuel feeding of middle air blower gear-box 7 afterwards.Oil strainer 4 is installed in the mounting bracket of the side of air blower petrol station 8, for filtering
Lubricate well cuts.Main oil pump 1 is connected with the port of export of auxiliary oil pump 4 by steel pipe with the arrival end of oil strainer 5.
The temperature-sensing valve 5 is three-way temperature control valve, makes A, B, C mouth that its three ports are respectively temperature-sensing valve 5；Then oil strainer
4 port of export is connected by steel pipe with the A mouths of temperature-sensing valve 5；The B mouths of temperature-sensing valve 5 pass through steel pipe and air blower gear-box oil-feed port
10 connections；The C mouths of temperature-sensing valve 5 are connected by steel pipe with the oil inlet of oil cooler 2；The oil-out of oil cooler 2 passes through steel pipe
It is connected with air blower gear-box oil-feed port 10.The oil cooler 2 is used for, to cutting oil, reducing lubricating oil temperature.
Thus, when oil temperature supplying is less than the minimum of temperature in use, the A mouths of temperature-sensing valve 5 are connected with B mouths, A mouths with
C mouths are disconnected, and lubricating oil is directly entered air blower gear-box oil-feed port 10 without subcooler, by the electrical heating of blast blower oil tank
The work heating lubricating oil of device 9.When oil temperature supplying is in the scope of temperature in use, and needs cooling, A mouths and the B mouths of temperature-sensing valve 5
Connect, A mouths disconnect with C mouths, lubricating oil is directly entered air blower gear-box oil-feed port 10, air blast machine oil without subcooler
The electric heater 9 of case does not work.When oil temperature supplying is higher than the minimum of temperature in use but is still not required to cooling, the A mouths of temperature-sensing valve 5
Connected with B mouths, A mouths and C mouths connect, lubricating oil is punished in temperature-sensing valve 5 to flow, and a part of B mouths through temperature-sensing valve 5 are directly entered drum
Gear case of blower oil-feed port 10, another part enter after oil cooler 2 cools down through the C mouths of temperature-sensing valve 5 and enter air blower gear-box
Oil-feed port 10, the electric heater 9 of blast blower oil tank do not work；Height-lubricating oil temperature that shunting is measured absolutely in lubricating oil temperature is high
When, the flow of lubrication of the C mouths through temperature-sensing valve 5 is big, otherwise the flow of lubrication of the B mouths through temperature-sensing valve 5 is big.When lubricating oil temperature height
When temperature in use, A mouths and the B mouths of temperature-sensing valve 5 are disconnected, and A mouths are connected with C mouths, and lubricating oil all cools down by oil cooler 2
Enter air blower gear-box oil-feed port 10 afterwards, the electric heater 9 of blast blower oil tank does not work.
