Abstract
The utility model proposes a kind of steam turbine generator lubrication system for subsequent use, comprise main oil pump, main fuel tank, main oil pump is connected by oil pipe with main fuel tank, main oil pump oil outlet is connected with oily device by fuel supply line, describedly to be connected with main fuel tank by return tube with oily device, also comprise a top petrol tank, the position of described top petrol tank is higher than the position with oily device, described top petrol tank top is communicated with main fuel tank, be communicated with fuel supply line bottom top petrol tank and be serially connected with safety check on the fuel supply line of upstream, joint, the normally closed solenoid valve linked with main oil pump is serially connected with between described top petrol tank and fuel supply line.When factory's electricity power-off, when main oil pump can not work, top petrol tank can be utilized and by the height difference between oily device to Turbo-generator Set fuel feeding, avoiding set main shaft and bearing to burn because lacking lubricant oil, ensureing the safe operation of Turbo-generator Set when power-off.
Description
Technical field
The utility model relates to friction test apparatus field, a kind of steam turbine generator of specific design lubrication system for subsequent use.
Background technique
At present, steam turbine of thermal power plant is in actual motion, and the macro-axis of turbine LP rotors, bearing need with oil lubrication and cooling.If the power-off suddenly of factory's electricity, main oil pump power-off, lubricating oil cycle interruption, macro-axis and bearing can not get lubrication and cooling, will cause tile kilning, ruin the heavy losses of axle.
Model utility content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of steam turbine generator lubrication system for subsequent use that also lubricating oil can be provided to supply to generator set after a loss of power.
For achieving the above object, the utility model adopts following technical proposals: a kind of steam turbine generator lubrication system for subsequent use, comprise main oil pump, main fuel tank, main oil pump is connected by oil pipe with main fuel tank, main oil pump oil outlet is connected with oily device by fuel supply line, describedly to be connected with main fuel tank by return tube with oily device, also comprise a top petrol tank, the position of described top petrol tank is higher than the position with oily device, described top petrol tank top is communicated with main fuel tank, be communicated with fuel supply line bottom top petrol tank and be serially connected with safety check on the fuel supply line of upstream, joint, the normally closed solenoid valve linked with main oil pump is serially connected with between described top petrol tank and fuel supply line.When running well, top petrol tank is full of lubricant oil by manually opened normally closed solenoid valve, when after factory's electricity power-off, normally closed solenoid valve is opened while main oil pump power-off, lubricant oil enters fuel supply line to oily device fuel feeding from top petrol tank, the normally closed closed electromagnetic valve when main oil pump energising recovers, recovers normal fuel injection.
Be serially connected with spill valve between described top petrol tank and main fuel tank, between described top petrol tank and normally closed solenoid valve, be serially connected with manually operated valve.
Oil cooler is serially connected with between described main oil pump and safety check.The cooling that oil cooler can accelerate lubricant oil is set.
The beneficial effects of the utility model are: when factory's electricity power-off, when main oil pump can not work, top petrol tank can be utilized and by the height difference between oily device to Turbo-generator Set fuel feeding, avoiding set main shaft and bearing to burn because lacking lubricant oil, ensureing the safe operation of Turbo-generator Set when power-off.
