Description
Technical field
The present invention relates to a kind of Seal Oil round-robin method and Seal Oil blood circulation, in particular relate to a kind of close for compressor
Oil sealing round-robin method and Seal Oil blood circulation.
Background technology
In modern enterprise, compressor is as a kind of indispensable power running equipment, thermal transition big with single-machine capacity
Efficiency is high, the steam flowing advantage such as high-speed and continuous, length in service life, applies to metallurgy, chemical industry, pharmacy, electricity the most widely
The fields such as power, boats and ships, nuclear power.
Compressor is mainly used in gas is carried out pressure-raising, and the gas in compressor still has a small amount of gas outside after comb
Infiltration, for preventing this portion gas from leaking, Seal Oil plays the part of important role, and Seal Oil enters from the floating ring of unit, simultaneously
Laterally with interior side inflow, wherein most Seal Oil through floating ring to exosmosis, owing to this portion gas does not contacts with process gas,
Therefore oil sump tank is continuing with together with lubricating oil, also sub-fraction Seal Oil is permeated in compressor through floating ring, is used for sealing
Process gas after comb, prevents process gas from leaking;Owing to this part Seal Oil contacts with process gas, thus will by with technique
Seal Oil after gas contact is passed through gs-oil separator, isolates gas therein, flows into oil after entering back into the regeneration of deaerating tank bubbling
Case is continuing with.
In traditional Seal Oil blood circulation, when instrument air stops suddenly for seasonable, due to atmospheric valve and the sealing of compressor
Oil regulation valve is all that gas-tight valve, therefore atmospheric valve and Seal Oil regulation valve all can be opened, on the one hand due to atmospheric valve standard-sized sheet, cylinder
Interior pressure is let out too fast, may result in reference gas pressure and reduces, and Seal Oil increases with the pressure reduction of reference gas;On the other hand due to
Seal Oil regulation valve standard-sized sheet, Seal Oil liquid level goes up very fast, as regulated not in time, Seal Oil can be caused from reference gas pipeline and
Labyrinth seal flows in the cylinder of compressor, causes process gas to be polluted by Seal Oil, and the process gas being contaminated can not be timely
Discharge, the catalyst activity of synthetic tower can be caused to reduce, even can loss of activity, cause serious consequence.

Bascule 114 connects chromacoder 115, and chromacoder 115 connects regulation valve 116.
Interrupt for preventing from causing because defecator breaks down sealing oil circuit, defecator 15 include the first filter 151, the
Tow filtrator 152, six-way valve 153, equalizer valve 154, restriction orifice 155, the port of export of first, second oil pump 141,142
Connecting the first port of six-way valve 153, the import and export end of the first filter 151 connects the second of six-way valve 153, the respectively
Three ports, the import and export end of the second filter 152 connects the six, the 5th ports of six-way valve 153, six-way valve 153 respectively
The 4th port connect regulation valve group 16, be communicated with pipeline 156, equalizer valve between first, second filter 151,152
154, restriction orifice 155 is located on this connecting pipeline 156, and Seal Oil can be through the first filter 151 or the second filter 152 mistake
Filter, after filter element changed by the first filter 151, can open equalizer valve 154, make the Seal Oil in the second filter 152 be filled with
First filter 151.
Seal Oil blood circulation of the present invention applies also for the system of any use Seal Oil device in addition to compressor.
The present invention uses the method that above-mentioned Seal Oil blood circulation carries out Seal Oil circulation, and the method comprises the steps:
1) Seal Oil in fuel tank 13 is pressurizeed through first pressue device 14, is filtered impurity through defecator 15 again,
2) above-mentioned Seal Oil after filtering flows through regulation valve group 16, is then divided into two-way, a road to flow into high tank 11, separately
A part flows into the sealing floating ring 21 of compressor 51, and this part of Seal Oil leans on the gas in compressor 51 cylinder through reference gas with high
The pressure reduction between static energy in the oil groove of position maintains gas in the jar not leak, when Seal Oil supply is interrupted suddenly, and high tank
11 provide Seal Oil for compressor 51, and when occurring that misoperation or instrument air stop suddenly for seasonable, compressor 51 is internal fast
Speed pressure release, regulation valve group 16 is opened the Seal Oil liquid level rapid increase caused in high tank 11, be can read liquid by liquidometer
Position height, when Seal Oil liquid level rises to predetermined altitude, can be by manual operation or by opening draining by the way of automatically controlling
Switching device on pipeline 111, makes Seal Oil flow into fuel tank 13 through air relief valve 112 rather than be entered by reference gas pipeline 61
Enter in compressor 51 cylinder, and then affect the gaseous mass of process gas in compressor cylinder,
3) part flowed in the Seal Oil sealed in floating ring 21 of compressor 51 outflows back to from the outside sealing floating ring 21
Fuel tank 13, another part enters and is sealed in floating ring 21, and this part Seal Oil is divided through oil gas together with the process gas in compressor 51
After device 12, oil product enters fuel tank 13, and process gas enters process gas reuse means 31, and the Seal Oil entering fuel tank 13 is pressed
Above-mentioned steps 1) described mode enters and circulates next time, reuse.
For making switching device to automatically control, making operation simpler, convenient, switching device includes that ball float 113, mercury-balance fill
Put 114, chromacoder 115, regulation valve 116, ball float 113 top connects mercury-balance device 114, mercury-balance dress
Putting 114 connection chromacoders 115, chromacoder 115 connects regulation valve 116, in step 2) in, normal condition
Under, ball float 113 is still in bottom by action of gravity, and the node of mercury-balance device 114 is the left side and centre, now breakage of circuit
Opening, chromacoder 115 does not works, and once operating mode occurs abnormal, and in high tank 11, liquid level rises very fast, and oil product arrives
Drain line 111, ball float by buoyancy, the node left side of mercury-balance device 114 and in separated, the right and centre
Node connect, circuit will close, formed loop, now chromacoder 115 works, and this output signal is changed
For the signal of telecommunication, opening regulation valve 116, Seal Oil returns to fuel tank 13 after air relief valve 112, it is ensured that oil product will not enter into compression
In the cylinder of machine 51, prevent oil pollution process gas.
In described step 1) in, after the pressurization of Seal Oil pressurized device 14, the first port through six-way valve 153 enters six-way valve,
The Seal Oil entered in six-way valve 153 enters the first filter 151 through the second port, close after the first filter 151 filters
Oil sealing enters six-way valve 153 through third connectivity mouth, then flows out through the 4th port of six-way valve 153, and enter in six-way valve 153 is close
Oil sealing can also enter the second filter 152 through clematis stem mouth, and the Seal Oil after the second filter 152 filters is through the 5th port
Enter six-way valve 153, then the 4th port outflow through six-way valve 153.
Embodiment described above is only to be described the preferred embodiment of the present invention, not limits the scope of the present invention
Fixed, on the premise of designing spirit without departing from the present invention, technical scheme is made by this area ordinary skill technical staff
Various deformation and improvement, all should fall in the protection domain that claims of the present invention determines.
