The classification of ac contactor purposes

Contactor is a kind of automation control of electrical appliances.Contactor is mainly used for frequent connected or mini electric motor diplomatic relations,dc,has a large capacity of control,remote operation,relay can realize timing operation and interlock control,all kinds of quantitative control and the pressure loss and under-voltage electric motors 12 volt protection,widely used in automatic control circuit,the main control object is motor,can also be used to control other electric power load,such as electric heaters,lighting,electric welder,capacitor Banks,etc.Contactor can be divided by accused of current type ac contactor and dc contactor.Here introduces the commonly used ac contactor.Communication ac electric

motor can be divided into the electromagnetic contactor and vacuum type two kinds.

High efficiency motor energy saving effect is remarkable Huge market upside

Efficient motor is refers to the general standard motor has high efficiency.Efficient motor using new motor design,new technology and new materials,by reducing the wastage of the electromagnetic energy,heat energy and mechanical energy,improve the output efficiency.Compared with the standard motor,motor using efficient energy-saving effect is very obvious,normally efficiency can be increased by 4% on average.Figures show that China's industrial production of energy waste is serious,the motor power consumption accounts for 64% of the total electricity consumption in our country,based on the analysis of domestic motor application,most still ac electric motor is given priority to with ordinary motor,represented by efficient motor energy saving products market space is huge.Efficient motor is refers to the general standard motor has high efficiency.Efficient motor using new motor design,new technology and new materials,by reducing the wastage of the electromagnetic energy,heat energy and mechanical energy,improve the output efficiency.Compared with the standard motor,motor using efficient energy-saving effect is very obvious,normally efficiency can be increased by 4% on average.

Statistics show that's about 1.7 billion kilowatts,annual power consumption of about 3 trillion KWH,motor power consumption accounted for 64% of China's total power consumption,industrial electricity 75% efficient motor in domestic existing stock motor proportion less than 5%,the production of high efficiency motors are mainly sold to electric motorforeign countries.At the same time,the application of highly efficient motor in China at present is only 23% ~ 23%.Although our country in 2008 will be included in motor system energy saving country one of the ten major energy conservation projects,www.dongfeng- motor.com 2009 also include high efficiency,super efficient motor application in huimin engineering,June 2,2010,according to the notice will be highly efficient motor in energy-saving products huimin project scope,make efficient motor marketing focus.Embarrassing situation is that the high efficient motor has promotion on the market for many years,high efficiency motor has not fully integrated into the market,at present efficient motor proportion is still relatively low.Efficient motor research and development in our country basic keep pace with the international level,the technical progress in recent years,very optimistic,especially on the motor efficiency and abroad there is no difference.

But it is a pity that our country produce IE3 motors domestic application of too little,most for export.Domestic well-known motor expert member of ren-yuan tang said.Statistics from the ministry of industry and information technology,according to the current domestic with motor in efficient accounted for only about 5%.To solve the problem of efficient motor in domestic promotion difficult,China's government departments to the New Deal is constantly,in order to promote the development of industry.Energy efficiency standards 2012 China once in order to speed up the promotion of high efficiency motor,organized to GB18613-2006 "the small and medium-sized three-phase asynchronous motor limited value of energy efficiency and energy efficiency rating" revision,completed by China standardization institute and other units of the new GB18613-2012 "the small and medium-sized three-phase asynchronous motor limited value of energy efficiency and energy efficiency rating" countries have released in May 2012,and on September 1,2012.

After implementation,the standard of energy efficiency products will be banned from production,sales of

imports."2013 special action plan for energy saving and green industrial development from the miit on

IE2/IE3 electric motor March 26,issued by the 2013 industrial energy saving and green development action plan for special notice,in 2013 will focus on promoting the implementation of motor efficiency under special plans.: special action to implement goals so as to realize the national industrial power saving 1% (30 billion degrees),explore the development patterns and industrial energy saving and green,implementation to point with surface,drive the industrial energy saving and comprehensive utilization of the whole work progress.In 2013,according to plan,miit will from the promotion of efficient motor,eliminate inefficiencies and both the motor system energy saving technical reconstruction in six aspects,such as promotion,elimination and 100 million kw motor and motor system,the reform more efficient motor market,promote the motor product upgrading and industrial upgrading.

In recent years,rope machine mechanical industry developing rapidly,rope machinery manufacturing

enterprises in China has developed quite rapidly,large and small enterprises has arisen.Rope

machinery development will bring many convenience to people's life.In today's society,is suitable for

processing a sword hemp fibers as raw material of rope machine,also suitable for processing with

other natural fiber or synthetic fiber as raw material of rope machine,for the people acmotortrading.blogspot.com has greatly increased the production efficiency.Rope machine,including the frame and installed on the base of the conveying mechanism,closing mechanism,motivation mechanism,conveying mechanism by central axis,synchronous transmission gear train no.1,left,right,square plate and arrangement between left and right square frame board four line tray,closing mechanism by the rope,accept,pendulum string axis,one traction rope shaft axis,the no.2 traction axis,horizontal bevel gear,shaft bevel gear,bearing,bearing right and left 2 synchronous transmission gear train,dynamic mechanism is composed of motor and pulley drive,motor to drive through the belt pulley,deputy and number one and number two synchronous transmission gear train connection,a synchronous transmission gear train drive conveying mechanism to complete the pay-off.

2 synchronous transmission gear train drive the closing mechanism complete the rope and the rope,the fully automatic rope machine,automatic line,the machine can produce two strands of rope,rope three or four strands of rope,high production efficiency,product quality is good,save time,save work,and effort.Rope of the necessary conditions Explain when we are in use today or should pay attention to about the rope mechanical conditions: 1,the first rope machine model according to the class,type classification principle.In block letters with Chinese pinyin "said class of rope machine,model code,if there are repeated,expressed by two typical Chinese pinyin",expressed in the main parameters of generator parts stator rope machine structural characteristics.This kind of product is behind the main parameters of filling series,the main parameters and the serial number with a dash between links. 2,the design of rope machine should conform to the technical requirements of rope process,rational layout,elegant shape,6v electric motor reliable performance,simple operation,designed so that it would be easy to repair when failure occurs,can improve the high seriation,generalization and standardization level,rope machine should be in accordance with the prescribed procedures approval of drawings and technical documents manufacturing; 3,rope machine power and control devices and to ensure that basic performance of rope machine accessories and the use of special tools shall be issued by factory to install,and then supply. 4,the last rope machine should not have the appearance of the surface pattern without obvious bulge,sag,rough and other damage defects,such as rope machine lacquer layer should be uniform color,as long as after reaching the above basic conditions,rope machine can use better.
