There is a 380-volt industrial sewing machine in the home. how can it be converted into a 220-volt household? With 12 UF,Up to 15 UF,You have changed a lot of this kind of motor yourself,This kind of motor is star-connected,One of the biggest defects is that the motor is very hot,The reason is very simple,It is popular to say that the rated voltage of each phase winding of the motor of the 380 V Star connection method is 220 V,But now I still use the star connection method to receive 220 V above,Then the winding says that the voltage is only 127 V,Motor output is insufficient,Also easy to heat,The only way is to change the original star connection method to the Triangle connection method,The midpoint of this kind of motor has been sealed in the winding,You can open the motor and find out the star,Then lead the three lines out and connect the original three lines into a triangle connection.After this, the motor is smaller than the original current,Large output,The power factor has also increased,It is not

Numerical control is programmed with G code,However, if it is too troublesome to use it to program a picture,It is better to directly use the set Software of the system to make a drawing cut.Hebei Chuangli electromechanical Technology Co., Ltd,Specializing in the production of various CNC cutting machines.G00------G01------G02------G03------G04------G05------G06------G07------G08------G09------G10------G16------G17------G18------G19------G20------G21-----G22------G220-----G23------G230-----G24------G25------G26------G30------G31------G32------Equal pitch thread cutting,G33------Equal pitch thread cutting,G34------G35------G40------G41------Tool Compensation--G42------Tool Compensation--G43------Tool offset--G44------Tool offset--G45------G46------Tool offset /-G47------Tool offset-/-G48------Tool offset-G49------G50------Tool offset 0 /-G51------G52------Tool offset-G53------Straight line

Who has an engineering profile? Thank you in detail! China is a country with a shortage of water resources,The per capita water resources are about 2200 M3,About 1/4 of the world average.Jinan city is one of the key water shortage cities in the country,For resource water shortage areas.Jinan is known for its 'spring city,Famous for spring water.Within the urban area,There are four spring groups in the distribution,Quantity,The flow is large,Real numbers are rare.However,Due to blind and over-exploitation of groundwater,The underground water level in Jinan dropped continuously,The spring water broke off.Especially since 1999,Jinan quanqun stopped spraying for 936 days.Reclaimed water reuse,It is an important way to solve the urban water resources crisis,It is also the fundamental way to coordinate urban water resources and water environment,Domestic sewage treatment and reuse,It can not only reduce the exploitation of groundwater,I
