In the present embodiment, the operation principle of lubrication regulation petrol station：After petrol station auxiliary oil pump is opened, the oil in fuel tank passes through fuel tank
Outlet, fuel-displaced valve and coarse filter, then export oil by oil pump.The oil of output is after subcooler is cooled down again through oil
Filter is filtered, the oil two-way after filtering, and fuel feeding is adjusted to steam turbine all the way, and another way reduces by pressure regulator valve
Oil pressure, fuel feeding is lubricated to steam turbine and centrifugal compressor.Steam turbine is then turned on, drives main oil pump to work, process is above-mentioned
Pipeline gives itself and compressor lubrication fuel feeding.Deng host work it is normal after, auxiliary oil pump shut down switch to it is standby.
In the present embodiment, the advantages of main oil pump uses turbine driven pump, is as follows：1st, after power cut of whole factory, during equipment coasting operation
It can lubricate；2nd, power saving；3rd, when control system goes wrong, be not in that external application oil pump is out of service and compressor is transported
OK.Only an auxiliary oil pump, cooler, filter in above-mentioned petrol station use standby design each other, during a normal use
Another is as standby, whole equipment downtime during preventing above unit failure.
Contain ball valve one, one, check-valves in pipeline after fuel pump outlet.Ball valve simultaneously closes off with fuel-tank outlet valve
Afterwards, oil pump can be dismantled or pump filter by suction is repaired and cleaned.The effect of check-valves is：After oil pump is closed, output
The oil gone will not flow backwards.When main oil pump start emergency bearing oil pump close when, main oil pump output oil will not flow backward to emergency bearing oil pump and
In fuel tank.Conversely, and so.
Pressure gauge, temperature-measuring element are provided with the pipeline that oil pump is connected with each other with cooler, primarily to measurement
Into before oil cooler, whether the pressure and temperature of oil pump output oil, examination meet design load.Set after oil cooler in pipeline
Pressure gauge, temperature-measuring element, differential pressure transmitter are equipped with, primarily to measure after oil cooler, the oily pressure loss,
Whether the temperature value of oil meets design load.Enter temperature alarming value as temperature value is unsatisfactory for design load, control element will be sent
Alarm.The differential pressure transmitter set before and after oil strainer on pipeline, primarily to the difference that measurement oil passes through before and after oil strainer
Whether pressure meets design load.Design load is such as unsatisfactory for, then by the set different value (alarming value, shutdown value) of design, is reported first
Alarm, operator is prompted to switch it to standby oil strainer.Otherwise when differential pressure reaches shutdown value, unit will interlock to stop automatically
Machine.
Oil pump is designed with two groups of pressure regulator valves.First group is located between oil pump and cooler, and effect is when oil pump output oil mass
Unnecessary oil is flow back in fuel tank and in next pressure regulator valve during more than the regulation needed for steam turbine, compressor, lubricants capacity
The preceding oil pressure being adjusted to oil pressure needed for Steam Turhine Adjustment.Second group is located at after the oily oil-feed port of regulation, and effect is to be adjusted to oil pressure
Oil pressure value needed for lubrication operation.
Accumulator installs the moment supplement oil mass and steam turbine moment regulation oil with regulation oil-feed port, switching for oil pump
Supplement.
The effect of top petrol tank is to work as compressor emergency shutdown, and when oil pump is closed, the oil in top petrol tank can guarantee that steam turbine, compression
Regulation, lubricating oil needed for coasting operation in machine certain time.A check-valves is also set up after oil strainer on pipeline, effect is to work as machine
Group is shut down, and when main oil pump is closed, the trapped fuel in the oil and unit of top petrol tank outflow will not flow back to each part of petrol station.So as to protect
When having demonstrate,proved shutdown, top petrol tank role.
The effect of oil mist separator is to make fuel tank top because mist of oil gas discharge caused by unit oil return is vented, in order to
Mist of oil gas is set to discharge emptying rapidly, fuel tank top is provided with a nitrogen charging gas port with abacus, using nitrogen in fuel tank
Constantly flowing and discharge, promotes the discharge of lubricator in fuel tank.
The scope of protection of the utility model is not limited to above example and its conversion.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to protection category of the present utility model.
