Description
Technical field
The utility model is related to centrifugal fan field, more particularly to a kind of centrifugal fan to lubricate the fuel feeding system of bearing
System.
Background technology
Centrifugal fan obtains extensively should due to efficiency high, stable performance in fields such as steel, metallurgy, electric power, chemical industry
With.The oil supply system of conventional centrifugal fan sliding bearing generally uses Lubricating-oil Station --- using electric oil pump to centrifugation
Ventilation blower sliding bearing conveys lubricating oil.But when the emergency cases such as device systems emergency power off occur, electric oil pump can wink
Between fuel cut-off, and blower fan still can carry out running down due to inertia, and in the state of the supply of no lubricating oil, what is run at high speed sets
It is standby to cause to damage.
The method for solving the problem in the prior art is by the way of Lubricating-oil Station plus top petrol tank, to stop in electric oil pump
In the case of fuel feeding, supplemented to centrifugal fan sliding bearing by top petrol tank and send oil, this kind of mode has structure type and answers
The shortcomings of miscellaneous, big and fluctuation of service that takes up room.
Utility model content
The purpose of this utility model is to provide a kind of oil supply system of centrifugal fan sliding bearing, the purpose is to electronic
Auxiliary oil pump adds the form of spindle nose pump to replace Lubricating-oil Station and top petrol tank, improves the safety and stability of fan operation.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of centrifugal fan lubricates the oil supply system of bearing, including electronic auxiliary oil pump, fuel tank, main oil pump, centrifugation are logical
Blower fan, filter, cooler, main oil pump are arranged on the lengthening spindle nose of centrifugal fan main shaft, electronic auxiliary oil pump and main oil
On oil line pipe between fuel tank and cooler, the output end of cooler connects centrifugal fan and slides by oil circuit for parallel connection of pumps
Bearing, filter is installed on the oil line pipe between cooler output end and centrifugal fan sliding bearing.
Compared with prior art, the beneficial effects of the utility model are：
A kind of centrifugal fan lubricates the oil supply system of bearing, under ensure that the system fuel feeding of normal operation, urgent
When the emergency cases such as power-off occur, main oil pump is driven by the running down of blower fan, can equally continue fuel feeding, it is ensured that fan safe, stabilization
Operation.The utility model structure type is simple, occupies little space, stable.
Brief description of the drawings
Fig. 1 is process chart of the present utility model.
Fig. 2 is the schematic view of the mounting position of main oil pump.
In figure：The electronic auxiliary oil pump of 1- fuel tanks, 2-, 3- main oil pumps, 4- centrifugal fans, 5- motors, 6- filters, 7- are cold
But device.
Specific embodiment
Implementation method of the present utility model is further illustrated below in conjunction with the accompanying drawings：
See Fig. 1-Fig. 2, a kind of centrifugal fan lubricates the oil supply system of bearing, including electronic auxiliary oil pump 2, fuel tank 1, master
Oil pump 3, centrifugal fan 4, filter 6, cooler 7, main oil pump 3 are arranged on the lengthening spindle nose of the main shaft of centrifugal fan 4, electricity
Dynamic auxiliary oil pump 2 and main oil pump 3 are connected in parallel on the oil line pipe between fuel tank 1 and cooler 7, and the output end of cooler 7 passes through
Oil circuit connects the sliding bearing of centrifugal fan 4, the oil-way pipe between the output end of cooler 7 and the sliding bearing of centrifugal fan 4
Filter 6 is installed on road.
The utility model is that the main-shaft spindle head of centrifugal fan 4 has been carried out into lengthening treatment, and main oil is mounted with spindle nose
Pump 3, main oil pump 3 uses gear pump in embodiment.Main oil pump 3 is connected in parallel in oil circuit with electronic auxiliary oil pump 2, and input is by oil
Pipe connects fuel tank 1, and output end connects cooler 7 by oil pipe.
When using, start electronic auxiliary oil pump 2 first before centrifugal fan 4 starts, lubricating oil is through subcooler 7, mistake
Filter 6 is the sliding bearing fuel feeding of centrifugal fan 4, and the motor 5 that power is provided for the main shaft of centrifugal fan 4 is started afterwards, is driven
Centrifugal fan 4 and the synchronous averaging of main oil pump 3, the start completion of motor 5 close electronic auxiliary oil pump 2 after reaching requirement rotating speed, this
When lubricating oil by main oil pump 3 through subcooler 7, filter 6 be the sliding bearing fuel feeding of centrifugal fan 4, realize steady running.
When the emergency cases such as emergency power off occur, main oil pump 3 continues as centrifugation in the case where the running down of centrifugal fan 4 drives
Ventilation blower sliding bearing fuel feeding, until entirely off, it is ensured that equipment safety.
The lubricating oil of the sliding bearing of centrifugal fan 4 is circulated in eventually returning to fuel tank by oil pipe.
