摘要： A method for filtering seawater onboard a ship, with a filtration device (2) that has an in particular cylindrical filter element (6) arranged in a tank (5), and a cleaning device for separating dirt from the filter element (6) and for carrying away a dirt concentrate phase, consisting of water and the dirt, from the filter element (6) and out of the filtration device (2); having the following steps: a) seawater is pumped into the filtration device (2); b) the seawater is introduced into the filtration device (2) at an inlet pressure P_ein, flows in the filtration device (2) through the filter element (6), and after the filter element (6) as filtered seawater – filtrate – has an outlet pressure P_aus; c) a concentrate phase – concentrate – which is removed using the cleaning device (11) at the filter element (6) of the filtration device (2) and is carried away from the filter element (6) has a concentrate pressure P_konz; d) the inlet pressure P_ein, the outlet pressure P_aus and the concentrate pressure P_konz are preferably measured using sensors (22, 23, 24) and are transmitted to a control device (21); e) a change in filter efficiency of the filter element (6) is recognized by determining a change in a contamination pressure difference ∆P
F = P_ein – P_aus between the inlet pressure P_ein and the outlet pressure P_aus; and/or f) a suction pressure difference ∆P
K = P_aus – P_konz defined as the difference between the outlet pressure and the concentrate pressure is controlled in dependence on the contamination pressure difference ∆P
F = P_ein – P_aus.

摘要： Embodiments of the present invention relate to a filtration device and method for filtering liquids. In conventional devices, a liquid is placed in a vial, and a plunger, having a filter membrane located at one end, is depressed into the vial, causing the liquid to pass through the filter membrane into the interior of the plunger, where it is stored until required for further processing. However, such plungers are typically made of a plastics material. It is undesirable to store the filtered liquid in contact with plastics for extended periods of time, as contaminants may leach from the plastics material into the sample. In embodiments of the present invention, a filtrate receptacle made from a different material to the plunger, such as a glass material, is located in the interior of the plunger and the filtered liquid collected in the filtrate receptacle after passing through the filter membrane. This allows the filtered liquid to be held isolated from the plastics material, thereby protecting it from contamination.

摘要： A filter assembly for a fuel delivery system for actuators and fuel control system of an aircraft engine includes a wash flow filter. Fuel flow velocity is increased through the filter through use of a recirculating passage that is effectively achieved through use of an ejector pump. A portion of the pressurized fuel delivered by the main fuel pump is diverted and serves as a motive fluid that scavenges unfiltered flow from downstream of the filter and recirculates or discharges the recirculated flow to an inlet of the filter. This provides increased velocity to maintain sufficient washing of the filter openings.

摘要： A screw press apparatus has frames, a screw shaft, an outside tube, a cylindrical screen, a screw blade, a supply pipe, and a cleaning pipe. The screen is fixed between the frames to the outside tube, and has a plurality of fine holes and covers the screw shaft. The screw shaft and the screen define a cylindrical space continuously extending from an upstream region to a downstream region. Raw liquid is fed from the supply pipe via an opening of the screw shaft to the upstream region of the cylindrical space. The cleaning pipe ejects cleaning water onto the screen. Sizes of the fine holes of the screen decrease gradually from the upstream region towards the downstream region.

摘要： The fuel filter assembly (14) includes multiple tubes (24) within a combination wash and barrier flow filter. The filter (14) is designed to be used alternately between conventional wash flow mode and periodic barrier mode. The tubes (24) are manufactured of a mesh or screen material. In wash flow mode, flow passes through the filter (14), some of the fluid exiting radially through the sidewalls (40) of the tubes (24). The sidewalls (40) filter particles out of the fluid and the particles blocked by the sidewalls (40) are washed out the second end of the tube (24). In barrier mode, the motive flow is suspended and all of the potential contaminant is collected on the screen. Over time the screen will become increasing clogged and the pressure drop across the screen will increase. By adding additional tubes (24) to the filter additional surface area of sidewalls (40) is obtained without requiring an undesirable lengthening of the filter (14).

摘要： A self-flushing fluid filtration arrangement is disclosed wherein an oil flow is separated in two different flows. A first flow is filtered through a filter element whilst a second flow is not filtered although it may flow through the element. The second flow continuously flushes the surface of the filter element to remove particles filtered from the first flow.
