The device is simple in structure, convenient to manufacture, flexible to mount and adjust and simple and efficient to operate.
Description
Technical field
The utility model relates to Balanced lubricating oil oil tank liquid level device, refers to particularly a kind of balance gas turbine and gas compression pump Lubricating oil tank level gauge.
Background technique
The gas steam combined cycle for power generation set lubricating oil system is a pressurization, pressure closed circulation system; specifically comprise: oil tank, lubricating oil pump, oil cooler, oil filter, valve and protective gear; when being unit operation, its major function provides appropriate lubrication and cooling for the unit lubricating component; the heat that while absorbing unit operation, bearing shell and lubricating component produce; prevent that bearing running hot from burning, axle journal is crossed thermal bending and is caused unit vibration to increase.In the Gas-steam Combined Cycle generator set, gas turbine engine lubricant system and gas compression pump lubricating oil system are the lubricating oil system of two independent operatings: wherein gas turbine engine lubricant system primary lubricant parts comprise the gas turbine bearing, dynamo bearing, auxiliary gearbox etc., the turbine oil system also provides work oil and cooling and lubricating oil for starting fluid converter simultaneously, during operation, part lubricant oil is after supercharging and filtering, control oil as gas turbine, another part enters the generator jacking oil system, support rotor when gas turbine starts or shuts down, prevent rotor bow, gas compression pump lubricating oil system primary lubricant parts are gas compression pump bearing and rotor.
As shown in Figure 1, the gas steam combined cycle for power generation unit exists coupling 7 sealing surfaces poorly sealed at present, during operation, gas turbine charge oil pressure (600kPa) is higher than gas compression pump charge oil pressure (255kPa), parts of lubricating oil flows to gas compression pump lubricating oil return pipe 9 by coupling 7 sealing surface gaps from the higher gas turbine lubricant pipe 5 of pressure, cause gas compression pump lubricating oil tank 4 liquid levels to raise, gas turbine lubricating oil tank 1 liquid level reduces.
For the problems referred to above; main by after shutting down at present; manually to gas turbine Lubricating oil tank 1, inject lubricant oil; the mode of discharging simultaneously gas compression pump lubricating oil tank 4 maintains gas turbine lubricant oil liquid level and gas compression pump lubricant oil liquid level in the normal range of operation of unit; this mode operation is more loaded down with trivial details, and the operation cycle is shorter, frequent operation; not only increase operator's working strength, simultaneously can not balance on-line gas turbine and gas compression pump lubricant oil liquid level.
Summary of the invention
The purpose of this utility model be exactly to provide a kind of simple in structure, can be in not shutdown situation balance gas turbine and the gas compression pump Lubricating oil tank level gauge of timely and effective balance gas turbine lubricating oil tank and gas compression pump lubricating oil tank liquid level.
For achieving the above object, the balance gas turbine that the utility model is designed and gas compression pump Lubricating oil tank level gauge, comprise the gas turbine group that is provided with the gas turbine lubricating oil tank and the gas compression pump group that is provided with the gas compression pump lubricating oil tank, on described gas turbine lubricating oil tank and gas compression pump lubricating oil tank, be respectively equipped with gas turbine group return tube and gas compression pump group fuel supply line, also comprise liaison tube, described liaison tube two ends are connected with gas compression pump group fuel supply line with the gas turbine group return tube respectively, described liaison tube is provided with flowmeter and manually operated valve.
Further, the diameter of described liaison tube is 10mm.
Further, described liaison tube is Stainless Steel Tube.
Compared with prior art, the utility model has the advantage of: designed balance gas turbine and gas compression pump Lubricating oil tank level gauge are simple in structure, easy to make, installation flexible adjustment, simple to operate efficient.Utilize gas turbine return tube pressure lower than gas compression pump fuel supply line pressure; by liaison tube, connect gas turbine group return tube and gas compression pump group fuel supply line; balance on-line gas turbine and gas compression pump lubricant oil liquid level have been realized; reduce unit disorderly closedown number of times; Combined Cycle Unit can Balanced lubricating oil liquid level fault in non-stop-machine situation; the gas turbine startup once consumes light oil 20t; after using gas turbine and gas compression pump lubricant oil liquid level Equilibrator; reduce and shut down number of times; lower the unit operation cost, improved unit operation efficiency.

Fig. 1 is the set lubricating oil system structural representation before improving.
Fig. 2 is the set lubricating oil system structural representation after improving.
Fig. 3 the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Set lubricating oil system structure before improvement shown in Figure 1, be explained in detail in background technique, repeat no more in this.
Balance gas turbine of the present utility model shown in Fig. 2 ~ 3 and gas compression pump Lubricating oil tank level gauge, comprise the gas turbine group 2 that is provided with gas turbine lubricating oil tank 1 and the gas compression pump group 3 that is provided with gas compression pump lubricating oil tank 4, on gas turbine lubricating oil tank 1 and gas compression pump lubricating oil tank 4, be respectively equipped with gas turbine group return tube 8 and gas compression pump group fuel supply line 6, also comprise that diameter is the stainless liaison tube 11 of 10mm, liaison tube 11 two ends are connected with gas compression pump group fuel supply line 6 with gas turbine group return tube 8 respectively, liaison tube 11 is provided with flowmeter 12 and manually operated valve 10.
During use, when oil tank liquid level malfunction alarm appears in the Gas Turbine Generating Units operation, operator can open manually operated valve 10 on the spot, make lubricant oil flow to from the higher gas compression pump group fuel supply line 6 of pressure the gas turbine group return tube 8 that pressure is lower, finally get back to gas turbine lubricating oil tank 1.Observation gas turbine lubricating oil tank 1 and gas compression pump lubricating oil tank 4 liquid levels change, and recover normal when the alert disappearance liquid level of gas turbine lubricating oil tank 1 liquid level minimum living, and gas compression pump lubricating oil tank 4 liquid levels also, when normal range of operation, are closed manually operated valve 10 simultaneously.
