Air source system for supplying air to a turbine engine by fracturing manifold equipment

A filtration system includes a particle counter configured to detect particles in a volume of fluid. The filtration system includes a control valve in fluid communication with the particle counter. The filtration system includes a controller in communication with the particle counter and the control valve. The controller may be configured to determine whether the detected particles exceed a predetermined threshold. The controller may be configured to command the control valve. The filtration system includes a filter in fluid communication with the control valve.

The invention provides an air filter air inlet system and a vehicle. The air filter air inlet system comprises a first filter and a second filter, wherein an air inlet of the first filter faces upwards so that air can enter the first filter in the direction perpendicular to the ground, an air inlet pipe of the second filter is communicated with an exhaust pipe of the first filter, and the exhaustpipe of the second filter is connected with an air inlet tail pipe. In the using process, even when one filter breaks down, the normal air filter air inlet requirement of the vehicle can be ensured. In addition, the first filter adopts the perpendicular air inlet arrangement mode, secrecy is achieved, the technical problems that in a horizontal air inlet scheme, many impurity particles enter the filters, and an engine air inlet system breaks down due to attack of front bullets are avoided, the filter element replacement frequency is lowered, and the air filter quality of the filter air inlet system is improved.

The invention relates to an air purifier (2) for purifying air by separating particles and/or organic matters. The air purifier includes a first ventilation device (6), a second ventilation device (8). a dust filter (10), a combined type filter (12) for separating dust particles and organic matters, and a switch device (14) for activating the first ventilation device (6) and/or the second ventilation device (8). The first ventilation device (6) is configured to generate airflow passing the dust filter (10). The second ventilation device (8) is configured to generate airflow passing the combined type filter (12). The invention also relates to a method for purifying air by separating particles and/or organic matters. The technical problem solved by the invention is to provide the air purifier and the method for purifying air, which can be used flexibly.

The invention relates to a dispersing device, in particular to a U-shaped coupling dispersing device of lubricating oil particles. The device comprises a supporting frame I, a connecting cylinder I, acirculating mechanism, a storage cylinder I, a filtering mechanism I, a treatment mechanism, a motor support, a power mechanism, a storage cylinder II, a feedback mechanism, a supporting frame II, anamplifying mechanism, a circulation connecting pipe and a closing mechanism; the circulation mechanism can provide sufficient power for circulation of lubricating oil; the filtering mechanism I is used for carrying out primary filtration on the lubricating oil; the filtered lubricating oil particles fall into the storage barrel I for collection; secondary filtration is carried out when the lubricating oil passes through the treatment mechanism; and the filtered lubricating oil particles fall into the storage barrel II for collection. When particulate matter is collected in the storage cylinder II, a compression spring is squeezed and the feedback mechanism can move downwards; the motion condition of the feedback mechanism is amplified through the amplifying mechanism and is convenient toobserve; and the lubricating oil flows back to the circulating mechanism through the circulation connecting pipe for circular filtration.

Filtration systems having a normal filtration mode and an enhanced filtration mode are described. In some arrangements, the filtration system is an air filtration system having a primary air filter element, a pre-cleaner, and a pre-cleaner bypass valve. Based on feedback from an intake air quality sensor the bypass valve is either opened or closed to selectively route intake air through the pre-cleaner during sensed dirty air operating conditions (e.g., heavy dust or moisture concentrations). In other arrangements, the filtration system is a liquid filtration system (e.g., a fuel or oil a secondary filter. The filtration system selectively routes the liquid being filtered through the main filter, the secondary filter, or a combination thereof depending on a detected event or sensed characteristic of the liquid.
