Highly Effective Inlet Filter (Fine)

Products :: Pumping equipment :: Highly Effective Inlet Filter (Fine)

Oilfield downhole equipment manufacturing.

The highly effective inlet filter is designed for oil refining, the intake of which is performed by the well sucker-rod pump from the oil formation and for the effective protection of the shut-off valve and the pump from suspended solids. It is achieved by the use of a fine titanium screen.

Structural features

Features	Advantages
Chromium plated corrosion resistant body	The increase in the fiItеr service life and the possibility of operation in highly aggressive ambient.
Titanium fine-mesh gauze	With increased endurance. The gauze meshes present a rhomb with the diagonal sizes 1.5 and 2 mm, that gives an opportunity to fiItеr mechanical inclusions of different size, increasing the pump service life, that precludes quick destruction of the gauze.

Design of Highly Effective Inlet Filter

The highly active inlеt fiItеr ФНВ-73.Б02.000 (FNV-73.B02.000) consists of the body (1), the two muffs (2), the casing (4), the valve (6), the body (5) and the screen (3).
There are threads on the ends of body (1) of the input fiItеr, on which muffs (2) are screwed. In the middle part of the inlet fiItеr body there is a special thread in the notches of which there are 200 holes O5 mm. A titanium screen (3) is installed on the middle threaded part of body (5) of the inlеt fiItеr. There is a casing (4) between muffs (2) having on its surface 56 holes. Body (5) is screwed in the lower muff (2) to which the valve is attached (6).

Description of High-Activity Inlet Filter Operation

The inlеt fiItеr ФНВ-73.Б02.000 (FNV-73.B02.000) is attached on the tubing string using its inner taper thread.
The intake of the pump passes through the holes in casing (4) of the inlеt fiItеr where big mineral particles are trapped.

Further the liquid passes through screen (3) of the inlеt fiItеr where small mineral particles and coarse sand are trapped. If the inlеt fiItеr is completely clogged a pressure difference appears that bends the valve tabs (6) and lets the liquid pass. The liquid passing through the valve provides the cleaning of the inlеt fiItеr screen. After the equalization of pressure the valve is closed and the inlеt fiItеr operates in a standard way.
