Abstract
The utility model relates to a secondary cooler for a gas turbine lubricating cooling system, belonging to the mechanism field. The lubricant back flow pipe line wind cooling device of the gas turbine is provided with a temperature probe; an automatic water spraying system controlled by an electromagnetic water valve is provided out of the wind cooling device; the temperature probe and the electromagnetic water valve are connected with the PLC program control unit of the gas turbine unit. The temperature probe transfers the temperature signal to the PLC program control unit; when the lubricant temperature value is raised to a specified value, the PLC starts the electromagnetic water valve; the automatic water spraying system starts to spray the water to the wind cooling device; when the lubricant is sprayed by the water and the lubricant temperature is decreased to the specified value, the PLC closes the electromagnetic water valve; the automatic water spraying system stops spraying the water to the wind cooling device. The secondary cooler for a gas turbine lubricating cooling system solves the problems that the wind cooling system of the gas turbine lubricant can not adapt to the high-temperature special environment of the desert and the lubricant is rapidly carbonated and becomes old, ameliorates the loading ability of the gas unit, reduces the failure rate of the equipment, abates the equipment attrition simultaneously, and causes the operation cost of the unit to be reduced.
Description

Present employed gas turbine incompatibility desert high-temperature work environment; when ambient temperature surpasses certain certain value; cooling needs when the gas turbine lubricating and cooling system promptly can not satisfy lubricant oil and normally moves; thereby cause regular high temperature alarm of this system or shutdown; the lubricant oil flash carbonization, the equipment failure rate height.
Summary of the invention:
The purpose of this utility model is to propose a kind of device that makes the cooling of gas turbine lubricating and cooling system secondary that is applicable to desert and hot environment.
The purpose of this utility model is achieved in that and comprises water source 1, water pipe 2, PLC program unit 3, circuit 4, electromagnetism water valve 5, temp probe 6, air cooler 7, spraying head 8, fan 9, lubricating oil return pipe 10, lube oil inlet pipe 11, temperature control fuel tap 12, oil pipe 13, oil pump 14, oil sump 15, temp probe 6 is installed on the lubricant oil reflux pipeline 10 of gas turbine air cooler 7, at the outside of air cooler 7 installing electromagnetism water valve 5, in order to control automatic water sprinkler system, temp probe 6, electromagnetism water valve 5 all links to each other with the PLC program unit 3 of gas turbine unit by circuit 4, the bottom of air cooler 7 is provided with fan 9, be connected with lube oil inlet pipe 11 respectively between oil pump 14 and the air cooler 7, lubricating oil return pipe 10, between lubricating oil return pipe 10 and oil pipe 13, temperature control fuel tap 12 is housed, is equiped with oil pump 14 in the unit oil sump 15.
Described automatic water sprinkler system is made up of water source 1, electromagnetism water valve 5, spraying head 8 and water pipe 2.
Temp probe 6 is installed on gas turbine air cooler lubricant oil reflux pipeline, at the automatic water spraying head 8 of air cooler 7 outside installing one covers by 5 controls of electromagnetism water valve, temp probe 6, electromagnetism water valve 5 all link to each other with the PLC procedure control unit 3 of gas turbine unit, temp probe 6 uploads to PLC procedure control unit 3 with temperature signal, after PLC computing relatively, the on off state of output control signal control electromagnetism water valve 5.When the lubricating oil temperature value rose to the automatic spray control temperature value of PLC regulation, PLC promptly opened electromagnetism water valve 5, and 8 beginnings of water spraying head are to air cooler 7 spraying waters automatically; When lubricating oil temperature when water spray cooling drops to the control temperature value of PLC regulation, PLC3 promptly closes electromagnetism water valve 5, water sprinkler system stops to air cooler 7 spraying waters automatically.
Owing to carry out such scheme, just solved the difficult problem that gas turbine lubricant oil air cooling system incompatibility is moved under hot environment, lubricant oil flash carbonization, problem of aging under the operation of desert high temperature particular surroundings have also been solved, improved the load capacity of combustion gas unit at high temperature season, reduced equipment failure rate, alleviated equipment attrition simultaneously, the operating cost of unit is reduced greatly.
Description of drawings:
Fig. 1 is the structural representation of gas turbine lubricating and cooling system secondary cooling apparatus
Embodiment:
Legend: 1, water source 2, water pipe 3, PLC program unit 4, circuit 5, electromagnetism water valve 6, temp probe 7, air cooler 8, spraying head 9, fan 10, lubricating oil return pipe 11, lube oil inlet pipe 12, temperature control fuel tap 13, oil pipe 14, oil pump 15, oil sump
Embodiment: as shown in Figure 1, Pt100 type temp probe 6 is installed on the lubricant oil reflux pipeline 10 of gas turbine air cooler 7, at the automatic water spray of installing one cover in the outside of air cooler 7 by 5 controls of DF1 type electromagnetism water valve. system, this system is made up of water source 1, electromagnetism water valve 5, spraying head 8 and water pipe 2.Temp probe 6, electromagnetism water valve 5 all link to each other with the PLC procedure control unit 3 of gas turbine unit by control wiring 4.
During operation, temp probe 6 uploads to the temperature signal of lubricant oil reflux pipeline 10 the PLC procedure control unit 3 of gas turbine unit by control wiring 4, after its computing relatively, control signal is controlled its on off state by control wiring 4 input electromagnetism water valves 5.When the lubricating oil temperature value rose to PLC procedure control unit 3 specified values, PLC procedure control unit 3 was promptly opened electromagnetism water valve 5, and automatically water sprinkler system begins to air cooler 7 spraying water from up to down, simultaneously, fan 9 rotates, and bottom-up blowing is lowered the temperature the lubricant oil in the air cooler 7 rapidly.At this moment, be higher than lubricant oil that oil temperature the requires SOLAR-190185-201 type temperature control fuel tap 12 of promptly flowing through and enter air cooler 7 by lube oil inlet pipe 11 once more and accept cooling, and do not enter each lubricating point 16 of unit; When the lubricating oil temperature that detects when temp probe 6 is lower than the control temperature value of PLC procedure control unit 3 regulations, PLC procedure control unit 3 is promptly exported control signal and is closed electromagnetism water valve 5 by control wiring 4, automatically water sprinkler system stops to air cooler 7 spraying waters, meets promptly flow through lubricating oil return pipe 10, temperature control fuel tap 12 and oil pipe 13 of lubricant oil that the oil temperature requires and enters each lubricating point 16 of unit.
Be equiped with oil pump 14 in the former gas turbine unit oil sump 15, its role is to by lube oil inlet pipe 11 to air cooler 7 pump oil.Can lubricant oil directly be flowed through when the oily temperature in the oil sump 15 was lower than the control temperature value of PLC procedure control unit 3 regulations? type temperature control fuel tap 12 and oil pipe 13 enter each lubricating point 16 of unit, and no longer enter air cooler 7.
