Abstract
The invention provides an electric lubricating oil scavenging pump of a combustion gas turbine. A motor is connected with a shaft through a coupler, wherein the shaft is connected with a pump shell through a sliding bearing; a flat key on the shaft is connected with four groups of gear banks: a gear bank A, a gear bank B, a gear bank C and a gear bank D; the gear banks are sealed by the pump shell at intervals; an inlet is formed in each gear bank; the gear banks share an outlet; each gear bank is composed of a pair of involute gears which is meshed with each other and is equal in number of teeth; the gear length ratio of the gear bank A to the gear bank B to the gear bank C to the gear bank D is 5 to 3 to 4 to 10; the gear banks share one outlet; and the outlet is connected with a check valve. The electric lubricating oil scavenging pump has the beneficial effects that performance indexes of the electric lubricating oil scavenging pump of the combustion gas turbine can meet the requirements on a lubricating system when the combustion gas turbine works in a low working condition and shuts down by reasonable arrangement of four sections of gear pumps with different ratios.

technical field:
The present invention relates to energy power industry field, the lubricating oil annex that a kind of shipbuilding industry uses, specifically a kind of gas turbine electric lubricating oil dump pump.
background technique:
Turbine oil assembly is machine band pump; when the low operating mode of gas turbine and shutdown because gas turbine rotor rotating speed is lower; lubricating oil assembly rotating speed is lower; the oil flow of each pump of lubricating oil assembly and rotating speed is caused to decline pro rata; and the oil flow required for gas turbine may change by another rule; for ensureing gas turbine proper lubrication, in the low operating mode of gas turbine, auxiliary lubricating oil need be set in time shutting down for dump pump lubricating engine together with lubricating oil assembly.
summary of the invention:
The object of the invention is to for realizing gas turbine lubrication system function, ensureing that gas turbine bearing bore lubricating oil is reliably drawn back when low operating mode and shutdown by gas turbine.
Technological scheme of the present invention is: gas turbine electric lubricating oil dump pump, comprise motor and pump case, motor is by coupling coupling shaft, axle is connected with pump case by sliding bearing, on axle, flat key connects four groups of gear trains: gear A group, gear B group, gear C group and gear D group, each gear train interval is closed by pump case, and each gear train has an import respectively, and each gear train has an outlet.
Described gear train, all intermeshes by a pair and the equal involute gear of the number of teeth forms.
Described gear train, the gear length ratio of gear A group, gear B group, gear C group and gear D group is: 5:3:4:10.
Described each gear train has an outlet, and outlet port connects safety check.
The present invention has following beneficial effect: by rationally arranging the different gear pump of four sections of ratios, the requirement to lubrication system when gas turbine electric lubricating oil dump pump property indices can meet the low operating mode of gas turbine and shut down.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Accompanying drawing 2 is left views of accompanying drawing 1.
1-axle in figure, 2-gear A group, 3-gear B group, 4-gear C group, 5-gear D group, 6-coupling, 7-motor, 8-pump case, 9-safety check.
embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1 composition graphs 2, gas turbine electric lubricating oil dump pump, comprise motor 7 and pump case 8, motor 7 is by coupling 6 coupling shaft 1, axle 1 is connected with pump case 8 by sliding bearing, and on axle 1, flat key connects four groups of gear trains: gear A group 2, gear B group 3, gear C group 4 and gear D group 5, and each gear train interval is closed by pump case 8, each gear train has an import respectively, and each gear train has an outlet.
Described gear train, all intermeshes by a pair and the equal involute gear of the number of teeth forms.
Described gear train, the gear length ratio of gear A group 2, gear B group 3, gear C group 4 and gear D group 5 is: 5:3:4:10.
Described each gear train has an outlet, and outlet port connects safety check 9.
By rationally arranging the different gear pump of four sections of ratios, the requirement to lubrication system when gas turbine electric lubricating oil dump pump property indices can meet the low operating mode of gas turbine and shut down.
Safety check 9 prevent when electronic lubricating oil dump pump do not work and lubricating oil component operation time from the reverse overflow of pressure inlet alignment suction line lubricating oil.
