After adopting such structure, the two-stage filter core of filter cleaner inside integrates, and decreases and taken up space, and fluid can improve filtering effect through two-stage filter core;

Fluid should reduce the water content in fluid after filter cleaner, if the moisture content in fluid is excessive, affect the combustion efficiency of fluid, this integrated form filter utilizes fluid through the first filter core, the filter precision of the first filter core is 2 ~ 5 μm, in filtration fluid while impurity, the free water in fluid can also be filtered, and the emulsified water in fluid is assembled and becomes free water, fluid is again through the second filter core, the filter precision of the second filter core is 25 ~ 35 μm, then free water remaining in fluid can be filtered, the water the most at last in fluid is separated with fluid.

The filter precision of the first filter core is 2 ~ 5 μm, and the filter precision of the second filter core is 25 ~ 35 μm, can greatly reduce fluid and flows through the resistance of the first filter core and the second filter core, meet the traffic requirement through this integrated form filter fluid.

This integrated form filter also comprises oil pump, and oil pump is arranged on and filters oil circuit end; After adopting such structure, compared to existing technology, oil pump is arranged on the situation of filtering oil circuit top, and the fluid after filtration flows in oil pump from filtration oil circuit, avoids the work of the foreign materials away oil pump in fluid.

This integrated form filter also comprises heater, and heater is arranged on and filters oil circuit top; After adopting such structure, fluid enters to filter before oil circuit and has to pass through heater heating, avoids that oil liquid temperature is too low affects filtering effect.

First filter core of this integrated form filter and the second filter core are all filter paper type filter core.

The cleaner bottom secction of this integrated form filter is provided with level sensor; After adopting such structure, can filter cleaner adduction catchment position high time, produce alarm signal.

Also differential pressure pickup is provided with in the filter cleaner of this integrated form filter; After adopting such structure, differential pressure pickup when filter cleaner internal differential pressure is excessive, can produce alarm signal.

Also be fixed with dividing plate in the filter cleaner of this integrated form filter, dividing plate will be divided into filtering cavity and collect cavity in filter cleaner, and dividing plate has some through holes and be communicated with filtering cavity and collect cavity, the first filter core and the second filter core are all arranged in filtering cavity; After adopting such structure, filter cleaner can be divided into two chambeies by function, the free water assembled after filtering enters collect cavity from filtering cavity through through hole, is convenient to discharge.

Second filter core of this integrated form filter is also tubulose, and the second filter core endoporus, by center support, center support has the gap for fluid circulation;

Housing is also welded with drainage tube, and drainage tube is communicated with oil outlet and the second filter core endoporus.

After adopting such structure, filter cleaner internal structure can be made more reasonable.

Embodiment

As shown in Figures 1 to 4

This integrated form filter comprises filter cleaner 1, oil pump 2 and heater 3.

Filter cleaner 1 is double filtration device, comprise housing 1a and inner filter core, housing 1a is roughly, the lower body closed, the housing 1a upper-end surface of filter cleaner 1 is provided with oil inlet hole 1b and oil outlet 1g, oil outlet 1g is in the middle part of housing 1a upper-end surface, the weep hole 1k communicated with outside is provided with bottom the housing 1a of filter cleaner 1, weep hole 1k is provided with valve, dividing plate 1m is also fixed with in the housing 1a of filter cleaner 1, dividing plate 1m will be divided into filtering cavity and the collect cavity of downside of upside in filter cleaner 1, dividing plate 1m has multiple through hole and be communicated with filtering cavity and collect cavity, the different double filtration device with routine of its filter cartridge construction, concrete structure is:
