THE DESIGN THAT THE MACHINA LIQUID PRESSES SYSTEM
KP3500 type whole liquids pressing to turn a dish type to drill machine is an our country the generation whole liquids press big caliber engineering to drill machine especially drill a hole the diameter can reach to a 35 ms depth 120 msThat machine adopts four motors to constitute Heng power back track to drive to turn dish first in the domestic and adopt a liquid to press an urn to replace a Yang machine ri weight big can reach to a 12 MNs speed quick ascend and descend steady can also be as occasion ari carry on adding to press to drill intoShould drill machine 1991 throw in the copper Ling usage in Yangtze River Bridge at the end of every year authenticate through a construction department in 1992 henceforth again u in the tiger door of Guangdong the big bridge the big bridge Nanking Yangtze River of the Xiamen a Cang in Fukien two bridges Hubei Jing sand Yangtze River Bridge Qian2 Tang2 Jiang in Zhejiang three the bridge etc the national important engineering becau its efficiency is high work steady but be subjected to constru
ction the unit consistent good opinion and have the honor of acquiring a construction department science and technology a progress accessit and national new product prizeTherefore the design applies a dependable liquid to press system and drill the usage function of machine to the pass importance to assurance
1 liquids press the basic principle of system design
Make u of an advanced technique at home and abroad and successful experience the concrete usage which combines our country state of the nation and drills machine requestTry hard for in brief with apply possibly the land utilization press a component to carry out to drill various action that the machine have with the minimal liquidSo can lower to break down occurrence all rate rai energy utilization and drill the credibility of machine lower a worker to labor strength

21 adjust soon way and liquid press a pump of choice
The liquid press adjust of system soon the way has already had no class to adjust soon with have class to adjust soon two major typesHave no class to adjust to soon have to adjust soon the scope be big can adapt a dissimilarity to drill into the request of craft but change to measure control back track and liquid to press a pump to drive organization more complicatedKP3500 type whole liquids press to drill machine to adopt 4 the t A7 V160 LV1 R Heng the power change to measure pump and 2 ts 2 QJM62-63 B low speed to greatly twist a Ju liquid to press motor to constitute Heng power to adjust soon system have class to become soon with have no the class become to soon knot to put together and openned widely to adjust soon scope and while adjust soon dont need to be reduce expens and overflow to flow the energy make u of more reasonable efficiency Gao but have fever little
Becau drill the machine construction geologic strata circumstance complications load to much change request to drill function with load of the variety automatically regulates to turns soon and turn Ju but the Heng power change to measure system and can adapt a request of load the work condition namely with load of increment the system can automati自残
买西瓜cally lower to turn soon and the aggrandizement turns JuAlso can with imum limit make u of the power of source motive attain to the bestly drill into the effectThe A7 V160 LV1 R Heng power change the work characteristics of measure the pump is lie in it of row quantity can with load pressure of the variety automatically regulates with promi importation power clo Heng ttle valueIf dont account an efficiency the motor outputs power N then basically equals the power of pump importation as well is Heng value from the power formula of the motor N the Mn974 can know N Heng in fixed time M and n prent a pair of curves relation in the Heng power become under the control of measure the pump along with load of variety the motor outputs turn Ju M and turn soon an of n to press a pair of curves relation to automatically regulate can satisfy a work condition request it adjusts soon characteristic curve such as figure 1 show

For satisfying high pressure the need of big discharge reduce a liquid to press build of system price lift a high performance price ratio we cho to u to put to pack valvePut to pack valve to have to flow ability big act speed quickly combine function strong al completely x like structure tightly packed anti- pollution the ability be strong and be easy to integration etc advantageCombine an adoption integration a piece showed Zhao to let up size and weight
纪律作风建设23 motors choo
Engineering machine most requests to become soon low but turns Ju greatly so the low speed greatly twists the application that the Ju liquid press motor to become developping trend it is soon small with high speed to twist Ju motor to add and subtract the way of machine compare the advantage lay in to reduce a machine to spread to move a piece structure simple arrange to maintain convenience work credibility turn Ju greatly and low speed stability good
