摘要:
An apparatus for conditioning fluid. In one embodiment of the present invention, there is an apparatus which comprises two filters and an electrically actuatable switching valve. Fluid provided to the apparatus may be routed to either filter by the switching valve. A controller positions the valve to provide fluid to a particular filter based on a measurement of pressure downstream of the filter, provided that the temperature of the fluid is above a predetermined level. Further, the invention includes proximity switches by which the controller can determine the coupling or uncoupling of a filter from the body. Various fuel heaters are provided for heating the fuel.

Disclosed and claimed is a method of removing contaminants from a process stream or stabilizing a system parameter in the process stream. The method includes providing a filtration system in communication with a controller, wherein the controller is operable to automatically initiate a flow from the process stream into the filtration system when the system parameter of the process stream is within above an upper threshold value and/or below a lower threshold value; and activating the filtration system, wherein the flow comprises a flow rate through the filtration system and the controller is operable to adjust the flow rate.

The disclosure relates to a fuel filter assembly, a filter element, and a method of draining water from a fuel filter assembly. The fuel filter assembly comprises a filter element with a water collecting space; the filter element being connected to a fuel pipe for feeding an upstream side of the filter element with fuel and for providing filtered fuel from a downstream side of the filter element to a combustion engine or parts thereof; a fuel pump arranged downstream from the filter element, wherein the fuel pump can be operated in a first mode for drawing fuel through the filter element and in a second, reverse mode for feeding fuel back to the filter element; a one-way fuel valve arranged upstream of the filter element allowing for flow towards the upstream side of the filter element; a pressure-actuated one-way drain valve in communication with the water collecting space.

摘要:
In a fluid filtration system with pressurized filtering means making use of filtration additives, a method for automatically controlling one ore more operation parameters of said filtering means, among which at least the dosed amount of said additives, comprising the following steps: before the start of a filtration cycle, establishing a predetermined reference value for the compressibility coefficient (nT) of the deposit that will be formed on said filtering means; during said cycle, periodically recording fluid pressure (P) and flow rate (Q) measurements upstream of said filtering means; after each recording step and on the basis of said measurements, calculating a value of said one or more operation parameters capable of keeping an evaluated compressibility coefficient (n) equal to, or in a neighborhood of, said reference coefficient (nt); and set the calculated value on said filtering means; said steps being iterated for subsequent periods up to the end of a filtration cycle.
