Whether inlet pressure, apical axis oil pressure, lubricating oil pressure and interlocking the correlated condition such as put into is discriminated whether normally to carry out start and stop
Relevant device.
The 1# jacking(oil) pumps allow the entry condition to include that 1# jacking(oil) pump thermocouples are not operating with 1# jacking(oil) pump entrance pressures
Power is normal, and 1# jacking(oil) pumps allow to start.
The 2# jacking(oil) pumps allow the entry condition to include that 2# jacking(oil) pump thermocouples are not operating with 2# jacking(oil) pump entrance pressures
Power is normal, and 2# jacking(oil) pumps allow to start.
The pump interlocking switch entry condition is included in the case of interlocking switch puts into has low pressure to believe in apical axis oil pressure switch
Number or work pump inlet pressure is low or working barrel tripping operation.
The jiggering allows conditions permit of the entry condition including 1# jacking(oil) pumps or 2# jacking(oil) pumps and enters work shape
State and turbo-engine lube positive pressure are often and steam turbine watt apical axis oil pressure is normal.
The jiggering trip condition includes that claim 1# jacking(oil) pumps enabled condition or 2# jacking(oil) pumps allow trip bar
Part is unsatisfactory for or steam-turbine lubrication oil pressure is abnormal or steam turbine watt apical axis oil pressure is abnormal.
The beneficial effects of the present invention are：PLC is allowed to jacking(oil) pump inlet pressure, apical axis oil pressure, lubricating oil pressure and
Whether interlocking the correlated condition such as puts into is discriminated whether normally to carry out start and stop relevant device, and meeting emergency can also be opened by pressure
Stop carrying out control device.Ensure the safe and stable operation of main equipment to greatest extent, optimize logic processed and control loop, allow protection
The related protection of turbine bearing pad can be played a role truly, and the optimization in loop is convenient to be understood, beneficial to the behaviour of operations staff
Make.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Specific embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
A kind of generator jiggering and jacking(oil) pump system, it is characterised in that：
Including drive generator amature rotation jiggering and for feed tray Chinese herbaceous peony forced feed lubrication 1# jacking(oil) pumps and
Standby 2# jacking(oil) pumps chain with 1# jacking(oil) pumps.
A kind of generator jiggering and jacking(oil) pump control method；Entry condition, 2# jacking oils are allowed including 1# jacking(oil) pumps
Pump allows entry condition, pump interlocked startup condition, jiggering permission entry condition, jiggering trip condition, by PLC to jacking(oil) pump
Whether inlet pressure, apical axis oil pressure, lubricating oil pressure and interlocking the correlated condition such as put into is discriminated whether normally to carry out start and stop
Relevant device.
The 1# jacking(oil) pumps allow the entry condition to include that 1# jacking(oil) pump thermocouples are not operating with 1# jacking(oil) pump entrance pressures
Power is more than 0.03MPa, and 1# jacking(oil) pumps allow to start.
The 2# jacking(oil) pumps allow the entry condition to include that 2# jacking(oil) pump thermocouples are not operating with 2# jacking(oil) pump entrance pressures
Power is more than 0.03MPa, and 2# jacking(oil) pumps allow to start.
The pump interlocking switch entry condition is included in the case of interlocking switch puts into has low pressure to believe in apical axis oil pressure switch
Number or work pump inlet pressure tripped less than 0.03MPa or working barrel.
The jiggering allows conditions permit of the entry condition including 1# jacking(oil) pumps or 2# jacking(oil) pumps and enters work shape
State and steam-turbine lubrication oil pressure are more than 0.07MPa and steam turbine watt apical axis oil pressure is more than 3.43MPa.
