Embodiment
We drive the supporting lubricating oil station of centrifugal compressor with reference to accompanying drawing to the electricity described in the utility model that is applied to below It is described further.
As shown in fig. 1, the electricity that is applied to of the present embodiment drives the supporting lubricating oil station of centrifugal compressor, including fuel tank 1, cold But device 2, oil strainer 3, top petrol tank 4, oil transportation part 5 is provided between the fuel tank 1 and cooler 2, the oil strainer 3 Front and rear in-out end is parallel with differential pressure transmitter 21, and lubricant oil feeding pipe road 6 is provided between the oil strainer 3 and top petrol tank 4, The top petrol tank 4 is connected by top petrol tank oil spilling pipeline 41 with fuel tank 1, and the oil transportation part 5 includes main oil pump 51, pressure The main oil pipeline and at least one by stand-by pump 53, pressure gauge 9, coarse filter that table 9, coarse filter 52, safety valve 8 form 52nd, the standby oil pipeline that safety valve 8 forms, be sequentially provided with the lubricant oil feeding pipe road 6 thermometer 91, regulating valve 92, Pressure gauge 9, check-valves 90, accumulator 63, lubricating oil oil-feed port 62, the top petrol tank 4 are connected with three valve groups 64.The fuel tank 1 be provided with electric heater 11, pouring orifice 12, nitrogen charging mouth 13, manhole 14, liquid level gauge 15, the total mouth 16 of oil return, platinum resistance thermometer sensor, 17, peace Blast pipe equipped with oil mist separator 18, fluid level transmitter 19 and thermometer 91, the bottom of the fuel tank 1 is additionally provided with oil filter Inlet port 101 and sewage draining exit 102, oil filter oil inlet.The lubricating oil oil-feed port 62, oil strainer 3 pass through the row with visor Feed channel 103 connects fuel tank 1.Pipeline between the oil transportation part 5 and cooler 2 is provided with pressure gauge 9, is connected with fuel tank 1 With on the pipeline described in the overflow pipe of regulating valve 92, thermometer 91 and pressure transmitter 22 between cooler 2 and oil strainer 3 Provided with thermometer 91 and platinum resistance thermometer sensor, 17.The cooler 2 connects fuel tank 1 by the cooler blast pipe 23 with visor.It is described Check-valves 90 and ball valve 7 are equipped with main oil pipeline, standby oil pipeline.The top petrol tank 4 is provided with liquid level gauge 15.
In the present embodiment, the operation principle of the lubricating oil station:After petrol station main oil pump is opened, the oil in fuel tank goes out by fuel tank Mouthful, fuel-displaced valve and coarse filter, then export oil by oil pump.The oil of output is after subcooler is cooled down again through oily mistake Filter is filtered, and the oil after filtering reduces oil pressure by pressure regulator valve again, and driving centrifugal compressor to electricity is lubricated fuel feeding.
In the present embodiment, the oil pump in petrol station, cooler, filter uses standby design each other, a normal use When another makees 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 when expelling oil mass needed for heart compressor lubrication more than electricity.After second group is located at filter, effect It is that oil pressure is adjusted to the electric oil pressure value expelled needed for heart compressor lubrication operation.
Accumulator is installed at lubricating oil oil-feed port, the moment supplement oil mass supplement for oil pump switching.
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 electricity expels heart pressure Lubricating oil needed for coasting operation in contracting machine certain time.A check-valves is also set up after oil strainer on pipeline, effect is to work as unit Shut down, 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 ensure During 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.
