1.SummarizationCNXQ Series Twist-bladder Accumulator was researched and development by both Zhaori and one graduate school of China Spaceflight, and it’s made from a twist compound material. This new style accumulator bears many advantages, for instance, light-weighted, high-pressure resistant, erosion resistance, low-temperature resistant, tiredness resistance, good capacity and etc. Moreover, this accumulator has passed through the technique authentication of this graduate school, filled up the blank of research industrialization in this kind of material, formed autonomous intellectual rights and has been applied the patents.CNXQ Series adopts high-capacity fiber reinforced composite instead of traditional materials, and in this way the weight will reduced by half. This product is widely used in spaceflight and hydraulic pressure self-adjusting device of air bus. Pulse of absorptive pump make it calm and it tallies with high standards of spaceflight, and it’s also fitting for trigging power reuse of hydraulic pressure bus as well as special environment. At present, the maximum working pressure is 100Mpa.2.Working PrincipleOil liquid actually can not be compressed, so it can’t cumulate pressure energy. Capsule accumulator works based upon the principle that gas (Nitrogen) compressibility can be used for cumulating liquid (Viz. adopting Nitrogen as compress medium).Capsule accumulator is made up with oil liquid part and capsule with hermetic separating part (inside contains Nitrogen). Loops of oil liquid and liquid pressure are communicative. Therefore, when pressure hoists, oil liquid enters into capsule accumulator, then gas will be compressed; While when pressure descend, compressed gas swells, then oil liquid is pushed back to loop.
4. Order Explanation
a.When ordering, please write down type, symbol and full name, such as working pressure 20Mpa, nominal capacity 40L, ventage shell structure, hydraulic oil as working medium, connect mode is screw, twist-bladder accumulator: CNXQ-40/20-L-A.b.If you have any special need for pipeline accumulator, please contact with us!c.We keeps the patent of design rejiggering right, no further notification for rejigger.
Winding bag accumulator of CNXQ series is another new bag accumulator with winding composite material developed by our company, which is light, high-pressure and corrosion resistant, cryophylactic, antifatigue and highly performing. The CNXQ series products adopt high-performance fibre reinforced composites to replace the traditional materials,which make the winding accumulator lighter than the half of accumulator made by steel. they are widely used in hydraulic automatic regulation systems of aerospace engineering and buses.The current highest pressure is up to 100Mpa.
