摘要： A method for cleaning substrates includes rotating a substrate; delivering deionized water on a surface of the substrate for pre wetting the surface of the substrate; delivering chemical solution with high temperature on the surface of the substrate for cleaning the surface of the substrate; changing the rotation speed of the substrate to a low rotation speed, and moving a ultra/mega sonic device. The method further includes turning on the ultra/mega sonic device and supplying a constant or pulse working power in a first cleaning cycle; turning off the ultra/mega sonic device, and delivering a high temperature chemical solution or deionized water. The method further includes turning on the ultra/mega sonic device and supplying a constant or pulse working power in a second cleaning cycle; turning off the ultra/mega sonic device, and delivering rinse chemical solution or deionized water on the surface of the substrate; and drying the substrate.

摘要： An analysis method of absolute energy efficiency and relative energy efficiency of the compressed air system. For the compressed air system operating in a form of a single compressor, a gas flow rate and a corresponding operating power of the compressor operating in the single compressor model are measured under a specified flow rate. Meanwhile, influencing factors of the compressor operation are monitored. The absolute energy efficiency of the compressor is defined, and a curve of the absolute energy efficiency of the compressor varying with the operating time versus the above factors are plotted in a same coordinate system. Obtaining absolute energy efficiency data of the compressor in a corresponding state. By analyzing the absolute energy efficiency under corresponding conditions and based on the corresponding chart, the actual unit consumption of a given single compressor and its changing rule under different production and environmental operating conditions can be intuitively analyzed.

摘要： The present technology provides an electrically powered hydraulic fracturing system having pumps for pressurizing fracturing fluid, piping for carrying fracturing fluid, and vibration reducing equipment for use with the piping. The vibration reducing equipment includes helical coils that support the piping. The coils are made of a wire rope made of strands of steel cable twisted together. Grooved fittings are provided on some piping connections, and which allow pivoting between adjacent fluid conveyance members. Swivel joints are strategically located in the piping which allow rotational flexing between adjacent sections of the piping; thereby attenuating vibration in the piping but without stressing the piping.

摘要： A device and method for operating a fluid-guiding device, including an electrically operated fluid pump, which delivers fluid from a fluid sump of the fluid-guiding device and supplies it to at least one fluid consumer. A fluid volume in the fluid sump as well as a current intensity of the electric current taken up by the fluid pump and modeled on the basis of the rotational speed of the fluid pump are ascertained, and a comparison value is determined from the modeled current intensity. A deficient fluid supply of the fluid-guiding device is inferred if the fluid volume is greater than a threshold value and a measured current intensity of the electric current taken up by the fluid pump is less than the comparison value.

摘要： Provided is a safety valve (10) comprising a body (12) which defines an incoming fluid passage (14) and a return fluid passage (20). The incoming fluid passage (14) generally enables a fluid to pass from a fluid reservoir (18) through the body (12) to the tool head (16). The return fluid passage (20) generally enables a fluid to return from the tool head (16) through the body back to the fluid reservoir (18). The body (12) further comprises a diverter (22) which is displaceable between an active position and an inactive position. When the diverter (22) is in the active position, the diverter (22) redirects the fluid via a shunting passage (24) from the incoming fluid passage (14) to the return passage (20) to prevent operation of the tool head (16). Conversely, when the diverter is in the inactive position, fluid is allowed to pass freely through the incoming and return passages (14) and (20), respectively, to allow operation of the tool head (16).

摘要： A pumping system and a pumping method implemented with the pumping system. The pumping system comprises a solar panel performing a photovoltaic conversion based on an insolation level including a first insolation level and a second insolation level; a fuel reservoir containing a fuel in a liquid state; an electric motor; a pump rotatable by the electric motor to pump the fuel; and a first motor drive converting electrical energy supplied by the solar panel to drive the electric motor at a first speed when the insolation level is at the first insolation level and at a second speed, slower than the first speed, when the insolation level is at the second insolation level, thereby pumping the fuel at a first rate and a second rate, respectively.

摘要： Disclosed is an embodiment that introduces a novel system to pump fluids, or, gases or, semi-solids, or, solids, from one place to another. Conventionally, a motorized pump systems are used to pump any given fluid from one position to another, nonetheless, in this invention not only a new system of pumping fluids is so introduced, but, existing functions of a conventional motorized pumping systems are saliently augmented by the pipe pump system. The pipe pump functions basically, by a series of electromagnets, that are placed around a flexible and resilient tube, (a rubber tube, for instance), and when these said electromagnet arrangements are actuated, then, that causes the pipe pump to pump out fluids, by squeezing on the fluids, or gases, contained within.
