Description of the embodiments
A novel turbine thin oil lubrication station comprises two parallel alternating current oil pumps 1 and 2 and a direct current oil pump 3, wherein the two parallel alternating current oil pumps and the direct current oil pump are communicated with an oil tank 4; two alternating current oil pumps are used in a normal working state, one of the two alternating current oil pumps is used and the other one is used for standby, one direct current oil pump is used in an emergency state, and the alternating current oil pump is a vertical centrifugal pump; a cooler 5 is arranged behind the alternating current oil pump, a filter 6 is arranged behind the cooler, and an energy accumulator 7 is arranged on an oil path between the filter and the oil supply port and used for emergency oil supplementing; a top shaft oil supply way is additionally arranged behind the filter; the direct-current oil pump 3 is directly communicated with the oil supply port 8 through an oil path provided with a valve.
The top shaft oil supply way comprises two parallel oil pumps 9 and 10 connected behind the filter, the two parallel oil pumps are respectively communicated with a throttle valve 11 after passing through a one-way valve, and the throttle valve is communicated with a top shaft oil supply port 12.
The oil tank adopts throttling arrangement, and throttling arrangement is fixed in the oil pipe 15 of oil tank bottom, and oil pipe upper portion stretches into the oil tank, and the oil pipe lower part is equipped with control valve 16 below the oil tank, and oil pipe upper portion has seted up the oil extraction aperture 17 of multirow different height. When oil is required to be discharged, the oil level is higher than the top of the throttling device, and the oil is directly discharged from an inner hole of the oil pipe; when the oil level is lower than the top of the throttling device, the oil is discharged from the small oil discharge holes with corresponding heights on the oil pipe, so that the purpose of fully discharging the oil is realized.
The main oil pump and the auxiliary oil pump are vertical centrifugal pumps, different flow rates can be output according to the change of system pressure, and a user can adjust the centrifugal pump system according to actual requirements of the site so as to achieve the effect of energy conservation; when one oil pump fails and cannot normally run, the other oil pump (a standby pump) needs to be switched to continue to keep running normally, and in the switching process, the standby pump needs 3-5 seconds from starting to establishing oil pressure, and at the moment, the energy accumulator is used for emergency oil supplementing, namely the pressure of a system is maintained by releasing the oil in the energy accumulator, so that the pressure cannot be reduced to an alarm point, and the safety, balance and uninterrupted oil supply of a lubrication station are ensured; an oil pump driven by a direct current motor is selected, and when the on-site alternating current is accidentally powered off, the oil pump operates to protect the balance stop of the steam turbine.
