Pump and fan - water ring vacuum pump

Vacuum pneumatic conveying system,to take advantage of vacuum pump keep certain vacuum degree in the pipeline.Have large pump suction type suction pipe section,at startup is also commonly used vacuum pump gas filling water.The commonly used vacuum pump water ring vacuum pump.Water ring vacuum pump is actually a kind of compressor,it extracts container gas pressure motor magnet in above atmospheric pressure,the resistance will be able to overcome the exhaust gas discharged into the atmosphere.Water ring vacuum pump structure diagram is shown in figure 1-8.Twelve blade impeller 1 in a cylinder of the pump shell 2 eccentric.Inject a certain amount of water in the pump.The impeller rotates,motor run capacitor to water to form a water ring pump shell,the inner surface of the ring and the impeller wheel tangent.


Due to different heart pump casing and impeller,the right wheel and water intake space between electricalmotor1.blogspot.com 4 gradually expand,thus forming a vacuum,making gas by the intake pipe 3 into the pump intake space 4.Then gas into the left side,due to the hub ring between volume was increased gradually and the compression pressure,so the exhaust gas space outside the exhaust pipes of 5 and 6 is to pump.Vacuum pump should be ac electric motor constantly replenish water at work to ensure formation water ring and take away the friction heat.China's production of water ring vacuum pump with SZ and SZB,the former top pressure of 205.933 Kpa (as compressor available).SZB is small cantilever type vacuum pump.Table 1-3 is SZ water ring type vacuum pump performance profile.

The investment cost recovery fast economic potential

High efficiency and energy saving motor is very 6.5hp gasoline generator setsuitable for textile,fan,water pump,compressor,by recoverable motor acquisition cost electricity saving about two years.For example: a rated power is 7.5 kw,the energy efficiency of grade 3 of Y2-132-m-4 change into the same rated power,the energy efficiency level to level 2 YX3-132-m-4 efficient motor,its performance indicators such as table 1.According acmotor2.blogspot.com to the formula can be unit of electricity saving amount: 7.5 (1/0.87-1/0.901) 1=0.2966 kw? H,can calculate its investment cost recovery.Choose efficient motor,power saving effect is obvious,all update motor can be recouped in 1 ~ 2 years of investment.The service life of the equipment as the transformer and motor for decades,with high efficiency motor instead of high energy consumption,not only can improve the efficiency of energy conversion,and in terms of life power saving effect is significant,long-term development for the factory to provide big driving force.

Close down backward production facilities application of highly efficient motor Backward in order to encourage inefficient motor exit the market,guide the existing motor enterprise gradually shift production efficient,state and local governments have taken some measures,and single phase asynchronous motor introduced the corresponding policies,encourage the development

of high efficiency and energy saving motor.Such as the ministry of finance,national development and

reform commission jointly issued "about huimin projects to promote efficient motor energy saving products" detailed rules for the implementation of the notice,the level of energy efficiency for primary and secondary low-voltage three-phase asynchronous motor 15 to 40 yuan/kw subsidies; 12 yuan/kw subsidies for high-voltage three-phase asynchronous motor; Rare earth permanent magnet motor for 40 low rpm generator alternator to 60 yuan/kw subsidies.

Subsequently,the government,the economic and information commission of guangdong province

issued "about the energy-efficiency subsidy issued by guangdong province motor detailed rules for the

implementation of the notice,the detailed rules,points out that the modified motor conform to the

2012 edition of the new standard of energy efficiency and guarantee the value of the high voltage three-phase asynchronous motor efficiency,the northwest area of guangdong province subsidy standards for motor 140 RMB/kw power before modification,and the pearl river delta region (including shenzhen) province subsidy standards for motor 100 RMB/kw power before modification,and to encourage local

according to the motor power before modification standard swallow the $200 per kilowatt.But the

standard computing project subsidies amount shall not exceed 50% of its total investment,and obtain

the motor system energy saving renovation subsidies enterprises,will not affect the application and other energy-saving enjoy national and provincial capital projects.However,have not reached,the government will impose punitive tariffs.Therefore,industrial enterprises should actively respond to national policy,the implementation of the application of highly efficient motor,backward inefficient motor,on the one hand,to reach the company's own saving energy and reducing consumption,reduce cost and performance of the corporate social responsibility; On the other hand,make full use of the government's subsidy policy,reduce the financial burden on enterprises.

Three-phase asynchronous motor starting method

Three-phase asynchronous motor is divided into squirrel-cage asynchronous motor and wound rotor asynchronous motor,the different structure,the boot method is different also,difference is very big.The start control lines.Squirrel-cage asynchronous motor full pressure start control circuit.Compared with the capacity of 8500w gasoline generatordc motor,asynchronous motor has small volume,light weight,the characteristics of moment of inertia of small.Therefore,in the asynchronous motor has been widely used in industrial and mining enterprises.In many industrial and mining enterprises,the number of squirrel-cage asynchronous motor to about 85% of the total number of electric drive equipment.Under the condition of the transformer capacity allows,squirrel-cage asynchronous motor should be as far as possible directly with full voltage start,can improve the reliability of control circuit,and can reduce electrical maintenance workload.The start of the three-phase asynchronous motor control line The three-phase asynchronous motor has simple structure,reliable operation,strong and

durable,cheap,convenient maintenance and so on a series of advantages.Most of the three-phase

asynchronous motor control line by the contactor,relay,knife switch,button,etc have a mix of contact

electrical appliances.One-way run electrical control circuit Main circuit QS by wholesalemotor.blogspot.com isolation switch,fuse FU,contactor KM normally open contacts,thermal relay FR heat element and motor of M.Control circuit by the starting button SB2,stop button SB1,contactor KM coil and normally open contacts,thermal relay FR normally closed contacts.Control circuit working principle is: 2,press the stop button to stop motor SB1,contactor KM coil electricity,its main contact and auxiliary contact are disconnected,motor from the power and stop operating.At this moment,even if loosen the stop button,because since the lock off contact,contactor KM coil will not electricity,motor will not start on its own. Only once rotor balancing machineagain press the starting button SB2,the motor will start running again.Unidirectional starter motor control circuit used to need only one direction of operation of small power motor control.For example small fan,water pump and belt conveyor and other mechanical equipment.This is one of the most commonly used,the most simple control circuit,can realize the automatic control of start-up and stop of the motor,remote control,frequent operation,etc.
