Description
Technical field
The invention belongs to dynamic field, more particularly to one kind switches load speed between power frequency rotating speed and permanent magnetic speed-adjusting
Equipment.
Background technology
Diagnosing System for Oil Pump, such as blower fan and pump, on the one hand, in order to run safety, design capacity is all larger, the opposing party
Face, because the equipment such as blower fan and pump are unable to oepration at full load, some equipment are even chronically at the flow of underload, blower fan and pump
Respectively by baffle plate and Valve controlling, larger restriction loss is caused.The power of load and motor speed are closed into cube ratio
System, during underload in the case of power frequency rotating speed motor consume energy in itself it is larger, if it is possible to when loading underload by motor speed
Appropriate reduction there will be larger consumption reduction space.Therefore, speed control device:Frequency converter and permanent-magnet speed governor, arise at the historic moment.
According to formulaWith(Q in formula1、Q2、n1、n2、P1、P2Different operating modes are represented respectively
Under flow, rotating speed and power), it is known that flow and rotating speed are into first power proportional relationship, power and rotating speed into cube direct ratio
Example relation, when demand volume is reduced, while direct proportion reduction rotating speed, it is only original cube relation to exert oneself, therefore drop
Power consumption reduction is significantly larger than rotating speed reduction amplitude during low motor speed.
The general principle of variable-frequency control technique is the relation being directly proportional according to motor speed to working power incoming frequency:n
=60 × f (1-s)/p (n, f, s, p represent rotating speed, incoming frequency, motor slip ratio, motor pole logarithm respectively in formula);Pass through
Change electric motor operation supply frequency and reach the purpose for changing motor speed.Current variable-frequency control technique comparative maturity, Ke Yiyong
In current almost all of varying duty slewing, energy-saving effect is notable.And variable-frequency governor can realize online switching, one
Denier frequency converter breaks down, and frequency conversion can be switched into power frequency operation online, the safe operation of whole system is not influenceed.But,
Because frequency converter is to strong environmental adaptability, to dust and sensitive, it is necessary to which frequency converter to be individually placed in the closed room of air-conditioning
Interior, on the other hand, frequency converter short life, maintenance are big, and module aging is very fast, replacement frequency is high, even if so current frequency converter
Extensive use, but be due to the limitation of its structure and performance, denounce always and exist and can not thoroughly solve.
Permanent-magnet speed governor is analogous to a class speed control device of frequency converter, and it is by the gas between copper conductor and permanent magnet
Gap is realized to be transmitted by the torque of motor to load.The technology realizes in driving (motor) and is driven (load) side not have
Mechanical linkages.Its operation principle is one end rare metal oxide ferro-boron neodymium permanent magnet and the interaction production of other end induced field
Raw torque, the torque of transmission can be just controlled by adjusting the air gap between permanent magnet and conductor, so as to realize that loading speed is adjusted
Section.Permanent-magnet speed governor floor space is small, it is not necessary to which house and air-conditioning temperature-reducing are installed in capping in addition, and usually maintenance is small, the equipment longevity
Life length, but there is a weakness that at present can not be commonly used in permanent-magnet speed governor, that is, because permanent-magnet speed governor is directly pacified
It between motor and load, once permanent-magnet speed governor breaks down, can only shut down, then permanent-magnet speed governor be overhauled again, such as
Permanent-magnet speed governor can not can only be removed quickly by failture evacuation and return factory, motor is moved forward, is connected again with load by fruit.
Can not be switched to quickly for not standby Diagnosing System for Oil Pump, after permanent-magnet speed governor failure power frequency be energy unit not
A receptible major defect is also main body power plant the reason for slowly not using permanent magnetic speed-adjusting in terms of blower fan.
