The invention relates to a low-pressure casting preparing method of an as-cast aluminum alloy hub. The method particularly comprises following steps of firstly, aluminum alloy matching and smelting; secondly, aluminum alloy refining; thirdly, strengthened aluminum alloy treatment; fourthly, low-pressure casting forming. According to the technical scheme, aluminum alloy component design, smelting and refining, an Al-5Ti-B intermediate alloy is added for strengthening the aluminum alloy, meanwhile, the content of impurity elements of Fe, Ti and Zn is strictly controlled, and the novel high toughness as-cast aluminum alloy hub free of heat treatment is prepared. The as-cast aluminum alloy hub prepared through the process shows the excellent strength and plasticity, and use needs are met; according to the low-pressure casting preparing method of the as-cast aluminum alloy hub, heat treatment is avoided, a large amount of heat treatment time is saved, and tools, hours and manual work neededby correction after heat treatment are saved, energy consumption is reduced, the production process flow of the aluminum alloy hub is simplified, the preparing cost is reduced, and the important application value is achieved.

A dual stage inflator 10 utilizes a housing 12 having two supplemental propellant combustion chambers 16 and 26, both symmetrically oriented within a primary propellant combustion chamber 34. Chambers 16 and 26 are formed to be substantially equivalent in dimensions and volume thereby simplifying the assembly and manufacturing process.

The invention provides a surface treatment technique for an aluminum alloy die casting. The technique comprises the following steps that 1, the aluminum alloy die casting is provided; 2, surface pretreatment is conducted on the aluminum alloy die casting; 3, cold spraying is conducted on the aluminum alloy die casting; and 4, alkaline electrolysis polishing treatment is conducted on the aluminum alloy die casting. By the adoption of the surface treatment technique for the aluminum alloy die casting, the defects of the surface of the aluminum alloy die casting are overcome, and an aluminum alloy die-cast product high in surface quality is obtained.

A combination axe, sledge hammer and pick (CASHP) that is particularly designed for use by firefighters. The CASHP includes a front end and a rear end. The front end has an upper section that functions as an axe blade and the lower section functions as a sledge hammer. The rear section includes a pick that can be utilized for a variety of functions. By incorporating three tools in a single structure the weight that a firefighter carries is lessened. Thus, reducing fatigue and the time that is required to cut through an obstruction to reach fire victims.

A layered testing and adjustment process for an injection well mainly solves the problems that an existing testing and adjustment process is carried out separately under a well shutin circumstance, the number of devices and tools is large, and long time is consumed. The specific testing and adjustment process includes the following steps that firstly, according to an existing throwing and fishing method, blanking plugs in eccentric water distributors in various layers are fished out and then blockage type flowmeters are thrown into the eccentric water distributors in the layers; secondly, different types of injection pressure are adjusted at the mouth of the well, the injection allocation flow of the whole well is 0-150%, and three to six points are selected for pressure adjustment; thirdly, the blockage type flowmeters in the layers are fished out, and testing data are obtained; fourthly, packer seal examining is implemented; fifthly, layered flow adjustment is implemented; sixthly, layered well testing and pressure measurement are implemented. The layered testing and adjustment process for the injection well has the advantages that under a well non-shutin circumstance, layered pressure measurement is completed at the same time, the number of devices and tools is small, operators have no special skill requirements or testing and adjustment experience, and data can be synchronized.
