Deep supercooled liquid oxygen filling and control system in low-temperature rocket launching site and method

The invention discloses a deep supercooled liquid oxygen filling and control system in a low-temperature rocket launching site and a method. The system comprises a ground circulating liquid oxygen storage tank, a negative-pressure liquid nitrogen bath type heat exchanger and an on-rocket liquid oxygen storage tank. Before launching, saturated liquid nitrogen and low-temperature helium are combinedto precool the on-rocket storage tank in sequence, after the precooling requirement is met, a large-flow filling mode is adopted for filling, and the purpose of rapid filling is achieved; and a coldhelium technology is adopted to dynamically adjust the pressure of a rocket storage tank and maintain large supercooling of liquid oxygen temperature, and meanwhile, a cold helium recycling technologyis considered based on a cryogenic liquefaction separation method. According to the system and the method, the functions of deep supercooled acquisition and high-flow rapid filling of liquid oxygen,advanced falling of a filling system, micro-positive pressure adjustment and large supercooling degree maintenance of the deep supercooled liquid oxygen of the on-rocket storage tank, helium cyclic utilization and the like are realized, and effective reference can be provided for deep supercooling and filling processes and a control mode of the liquid oxygen in the low-temperature rocket launchingsite.

Preparation method of Balsa wood core material of wind driven generator blade web

The invention relates to the technical field of wind driven generator blades, and particularly relates to a preparation method of a Balsa wood core material of a wind driven generator blade web. The preparation method comprises the steps of slicing, accurate grinding, dehumidification, double-end sawing treatment and gluing, and after pretreatment, shallow groove forming, punching, cloth pasting,deep groove forming, finished product inspection, template manufacturing, line drawing, edge cutting, mark writing, chamfering, IPQC process inspection, plate separation, dehumidification, laying inspection and packaging and warehousing are sequentially conducted. According to shallow groove forming, a plurality of shallow grooves are formed in at least one surface of the core material and are staggered on the surface of the core material to be arranged in a rectangular grid shape, and through holes penetrating through the upper surface and the lower surface of the core material are punched inthe intersection points of the multiple shallow grooves. According to the preparation method, three times of humidity detection are set, the moisture absorption possibility of the core material in the preparation process is further reduced, the risk of corrosion of bacteria and the like sealed in the core material in the operation process is reduced, and therefore the defects of the Balsa wood core material are effectively overcome.

Oil-well pump energy-storage enhancing device capable of compressing natural gas automatically

The invention discloses an oil-well pump energy-storage enhancing device capable of compressing natural gas automatically. The oil-well pump energy-storage enhancing device capable of compressing the natural gas automatically comprises an upper connector, an inner pipe, an outer pipe and a lower connector, wherein the upper connector is connected with an oil-well pump, and the lower connector is connected with a tail pipe. The oil-well pump energy-storage enhancing device capable of compressing the natural gas automatically is characterized in that the inner pipe and the outer pipe which are coaxial form an annular space with the sealed upper portion and the communicated lower portion, the annular space serves as a storage space of the natural gas separated from crude oil and an energy-storage and energy-release space for compression and expansion of the natural gas, and gas pressure-limitation holes with certain quantity and inner diameter are formed at the lower portion of the outer pipe and serve as a discharging passageway for residual gas in annular spaces of the inner pipe and the outer pipe. The oil-well pump energy-storage enhancing device capable of compressing the natural gas automatically is simple in structure, free of any moving component, stable, reliable, convenient to construct on site, and environment-friendly, and does not pollute the environment and an oil layer. The natural gas is compressed automatically as an energy-storage method, additional power is not needed, the problem of the service life in the energy-storage process of a compression spring is resolved at the same time, and the practicality is strong. The oil-well pump energy-storage enhancing device has a function as a gas anchor, is capable of preventing separated gas from entering the pump, and reduces the influence on pump efficiency when the gas enters the pump.
