Description

A kind of main lubricating oil bag type filtering method
Technical field
The present invention relates to ship piping system string and wash field, be mainly used in the one main lubricating oil bag type filtering method that mooring trial test stage main frame lubricating oil pipe system string washes work.
Background technology
Main frame lubricating oil wants the impurity in absolute guarantee's oil system cleaned complete before entering machine, a set of string should be adopted before machinery trials to wash system, main frame, piping, filter, heat exchanger, pump, valve and other all relevant equipment all should be washed complete by string, ensure, by observing and absolute cleaning after PE, any dirt can not be had.Before lubricating oil enters main frame, high and low pressure oil pump discharge line installs a temporary filter (F.T.), and temporary filter volume is originally large, filter core is heavy, and each all needs filter core chain block to hang out when changing filter paper, time-consumingly requires great effort again.So increase work efficiency by the method improving temporary filter (F.T.).
Summary of the invention
In order to overcome the shortcoming that existing filter exists, the present invention proposes a kind of main lubricating oil bag type filtering method.The method is filtered main lubricating oil by bag filter, solves the technical problem that main lubricating oil filters removal of contamination.
The scheme that technical solution problem of the present invention adopts is:
Bag filter structure:
Feet is installed the fuselage being provided with bleed outlet and upper cover, upper cover is arranged on fuselage by connecting bolt and sealing ring, in fuselage central lower, suction flange is housed, and is connected with outlet(discharge) flange at fuselage one side lower part, is supported with filter bag in fuselage by supporting basket;
On cover exhaust outlet and air bleeding valve be installed;
Rotary support is provided with between upper cover center and fuselage.
The installation of bag filter and method of operating:
1) bag filter is placed on the pipeline that need filter, connects after importing and exporting flange or pipe tooth, fixed;
2) metal Intranet is put into bag filter gently, Intranet neckline and bag filter tone are closed.
3) place filter bag, filter bag collar extension and metal Intranet neckline are coincide.
4) O RunddichtringO is put into O type groove, O RunddichtringO can not distortion or distortion, and filter bag pressure ring buckled by many bag hoses.
5) one hold upper cover handle, catch the other end of upper cover on the other hand, many bag hoses rotate top handwheel, and upper cover is aimed at bag filter mouth, slowly put down, natural concora crush is on O RunddichtringO and filter bag collar extension.
6) after upper cover is aimed at, two that tighten diagonal angle are hung cap simultaneously, and all caps that hangs are tightened one by one or wrung with in bat insertion suspension ring.
7) air bleeding valve being arranged on bag filter top is closed.
8) check that whether each connecting pipe is firm; Whether operating pressure is in allowed band.
9) output valve is opened.Open thermal source and enter valve, slowly heat up, make filter temperature be raised to assigned temperature.
10) open input valve at leisure, allow liquid slowly flow into and to be full of filter, prevent liquid from impacting filter bag suddenly, cause and break, then observing has No leakage.
11), after bag filter import and export being connected, with expansion bolt, bracing frame is fixed on ground level position, prevent liquid from impacting suddenly, pressure is excessive, causes the breakage to equipment.
Good effect, the inventive method difficulty of construction is little, the light easy cleaning of filter bag, replacing, and cost is low, and filter bag is reusable, easy to operate, and result of use is good, suitable plurality of liquid filter method application.

Detailed description of the invention
Bag filter structure: according to the figure, feet 8 is installed the fuselage 9 being provided with bleed outlet 7 and upper cover 1, upper cover is arranged on fuselage by connecting bolt 2 and sealing ring 3, in fuselage central lower, suction flange 6 is housed, being connected with outlet(discharge) flange 5 at fuselage one side lower part, in fuselage, being supported with filter bag 13 by supporting basket 4;
On cover exhaust outlet 11 and air bleeding valve 12 be installed;
Rotary support 10 is provided with between upper cover center and fuselage.
The installation of bag filter and operation:
1) bag filter is placed on the pipeline that need filter, connects after importing and exporting flange or pipe tooth, fixed;
2) metal Intranet is put into bag filter gently, Intranet neckline and bag filter tone are closed.
3) place filter bag, filter bag collar extension and metal Intranet neckline are coincide.
4) O RunddichtringO is put into O type groove, O RunddichtringO can not distortion or distortion, and filter bag pressure ring buckled by many bag hoses.
5) one hold upper cover handle, catch the other end of upper cover (many bag hoses rotate top handwheel) on the other hand, upper cover is aimed at bag filter mouth, slowly put down, natural concora crush is on O RunddichtringO and filter bag collar extension.
6) after upper cover is aimed at, two that tighten diagonal angle are hung cap simultaneously, and all caps that hangs are tightened one by one or wrung with in bat insertion suspension ring.
7) air bleeding valve being arranged on bag filter top is closed.
8) please check that whether each connecting pipe is firm; Whether operating pressure is in allowed band.
9) output valve is opened.Open thermal source and enter valve, slowly heat up, make filter temperature be raised to assigned temperature.
10) open input valve at leisure, allow liquid slowly flow into and to be full of filter, prevent liquid from impacting filter bag suddenly, cause and break, then observing has No leakage.Leak if do not occur, can start to filter.
11), after bag filter import and export being connected, with expansion bolt, bracing frame is fixed on ground level position, prevent liquid from impacting suddenly, pressure is excessive, causes the breakage to equipment.
Routine use: the pressure differential that the filtration system in work needs running check to import and export, when pressure differential reaches 0.05-0.1MPa, should change filter bag in time, breaks and supporting network damage in order to avoid pressure reduction crosses ambassador's filter bag.Warning: do not have in bag filter when pressure and uncap, otherwise left liquid may spray, and cause fluid loss and personnel's injury, check Pressure gauge, just can uncap when determining that internal pressure is 0.
Change filter bag: high efficiency filter bag is with made by meticulous fiber, the hydrophily of these materials is all more weak, can not be got wet by water in the surface of fiber, so as other filter core using same material, before use, all with the liquid that other surface tension are lower, it is moistening.Before installation, filter bag must be invaded a few minutes in the prewetting liquid mated with filter liquide by you.Correctly open bag filter upper cover, upper cover is put surely, filter bag is carefully taken out, put into new filter bag.Wait next time when changing after filter bag cleaning after replacing to use.
Monitoring filtering quality:
When liquid input pressure is stable, the pressure differential inside and outside filter quality and filter bag is closely related, if pressure reduction is too large, illustrates that the pore size filter of filter bag blocks, rate of filtration decline.Therefore, after bag filter is started working, pressure reduction should be made regular check on, the time changing filter bag is decided by the pressure reduction shown by the Pressure gauge of front and back, the pressure reduction that general filter bag can bear is about 0.05-0.1MPa, when pressure reduction reaches this interval, filter bag should be changed in time and break to avoid filter bag, affect filter effect.If pressure reduction declines suddenly, should stop immediately filtering, and check whether and leak.
Because former temporary filter (F.T.) volume is large, filter core is heavy, constructional difficulties, filter paper consumption are large.So former temporary filter (F.T.) is replaced by the method reduction difficulty of construction of bag filter, increase work efficiency.Bag filter is a kind of novel filtration system, and filter inside supports filter bag by metal Intranet, and liquid is flow to by entrance, flows out after sock filtration, and impurity is then intercepted in filter bag, and filter bag is replaceable or continue after cleaning to use.
