    摘要： A mixing pump device (1) used for fuel cells etc. has two inflow paths (51, 52), inflow side active valves (21, 22) arranged at the two inflow paths (51, 52), respectively, a pump chamber (11) into which liquids flow via each of two inflow paths (51, 52), four outflow paths (61, 62, 63, 64) for allowing a liquid mixed in the pump chamber (11) to flow out, and outflow side active valves (31, 32, 33, 34) arranged at the four outflow paths (61, 62, 63, 64), respectively. Further, a chamber (82) is formed between the pump chamber (11) and a branch point (80) at which the outflow paths (61, 62, 63, 64) branch off. The construction prevents a variation in the concentration of the liquid allowed to flow out of the outflow paths (61, 62, 63, 64) after the mixing in the pump chamber (11).

    摘要： Method and multipurpose apparatus for internally cleaning a hydraulic control system are disclosed. The method is carried out by establishing a turbulent flow of cleaning fluid through the hydraulic control system and maintaining the turbulent flow until the hydraulic control system has been cleaned without diverting a portion of cleaning fluid through a bypass valve, by use of a variable speed pump coupled to a fluid accumulator. The apparatus comprises a filtration system for cleaning up recovered fluid, a primary pump, an accumulator, a first manifold for fluid injection, a second manifold for fluid recovery, and a return conduit from the second manifold to the filter.

    摘要： A pumping system is described for pumping a first fluid (e.g., water) and selectively adding a second fluid (e.g., fire retardant chemical, fertilizer, pesticide, etc.) to the first fluid. The system includes a pump connected to a discharge manifold having discharge openings. An inlet conduit is connected between the pump and the first fluid. An eductor conduit is connected between the discharge manifold and the inlet conduit. A feed conduit feeds the second fluid to the eductor. A control valve selectively allows the second fluid to be fed to the first fluid. When the second fluid is not being added, the feed line is flushed without changing pressure.

    摘要： A method and apparatus is provided for decreasing the scrubber exhaust from gas panels, lower the cost of operation, lower the facilitation cost and power consumption by increasing the air velocity in areas of high potential risk of ignition. The apparatus includes a supply of compressed dry air (CDA) through the tubing with individual dispersion nozzles. The CDA dispersion nozzles can be installed at various key locations in order to provide additional ventilation turbulence and reduce potential dead zones inside the gas panel. Aspects of the invention help to save the energy and protect the environment by reducing the power consumption. In addition human safety shall be improved by minimizing the potential risk of ignition.

    摘要： In one embodiment, the present disclosure provides an apparatus and method for supporting a tubing bundle during installation or removal. The apparatus includes a clamp for securing the tubing bundle to an external wireline. In various examples, the clamp is external to the tubing bundle or integral with the tubing bundle. According to one method, a tubing bundle and wireline are deployed together and the tubing bundle periodically secured to the wireline using a clamp. In another embodiment, the present disclosure provides an apparatus and method for coupling conduit segments together. A first pump obtains a sample and transmits it through a first conduit to a reservoir accessible by a second pump. The second pump further conducts the sample from the reservoir through a second conduit. In a specific example, one or more clamps are used to connect the first and/or second conduits to an external wireline.

    摘要： The present invention provides a system which can automatically switch passages of a fuel supply line and a fuel return line when the pressure in a fuel return line becomes higher than a predetermined pressure. Even when the fuel supply and return lines are incorrectly connected, the present system can prevent the problem of damage to a fuel supply system and fuel leakage which may be caused by an increased fuel pressure.
