Transducer fan water pump controls plan to apply on water pump

Sen Lan water pump uses frequency control implement function brief introduction (1) BT12S series frequency control implement frequency control of series of Sen Lan BT12S implement, it is the company is fan, pump kind mechanical and the transducer of special number type of the design, divide outside having general transducer function, the time rotate function that still pump of loop of frequency conversion pump, frequency conversion secures two kinds of means (receive relay to expand board can come true, detailed sees operation instruction handbook) . PI regulator is established inside transducer, signal of feedback of two kinds of sensor inputs stock terminal VPF (voltage signal) with IPF (voltaic signal) , still have LA1 of LA2 of terminal of signal of FA of terminal of signal of fire control movement, high water level and low water terminal, and the floor level on pressure calls the police output terminal 30PA, 30PB and 30PC. The set that BT12S series transducer has unique Morpheus value and come to value (parameter F66 and F67) . Have two when water supply or when two above water pump, the Morpheus value that can ask according to the user set is appropriate and come to are worth. When pressure is worth under Morpheus small pump works; When be worth under come to when pressure advocate pump works; Contrary, when come to of pressure prep above is worth, advocate pump quits the job, small pump works; When Morpheus of pressure prep above is worth, small pump also quits the job, enter Morpheus state. Transducer of series of Sen Lan BT12S also can serve as general frequency control of course implement use. (2) SB60P and SB61P series frequency control implement structure of circuit of transducer of these two kinds of Sen Lan is identical, it is capacity limits differs only. It is the transducer of vector control type that uses digital processor DSP, performance is better. PID regulator is established inside transducer, also but outside receive patulous board undertake much pump runs circularly. 2. Fan water pump uses frequency control implement water pump of control program fan has with the control method of transducer a variety of, can choose according to particular case. A few kinds of commonly used program introduce below. (1) the hand is moved adjust this is a kind of the simplest control method, operate personnel to be indicated according to appearance namely, the hand is moved adjust the frequency of transducer in order to change wind force or discharge, satisfy manufacturing requirement. This kind of method agrees with the transducer of any type, commonly used the technical reformation at old equipment. FWD to turning signal inputs end, CM is the public end that inputs signal, SB is transfer switch. When SB closes, electromotor M to start; When SB disconnects, electromotor stops. Retain the starting unit of primary facility, plate washer, valve wide-open, make the same score season KM1, KM3 to put through, use transducer transmission. If transducer malfunctions or need overhaul, disconnect KM3, your KM2 puts through, use primary facility to start device and fender valve to have movement. Install to ensure complete, two contactor want KM2 and KM3 mutual and interlocking (include electric, machinery two kinds interlocking) . (2) frequency control implement this kind of method masters double position control simply, reliably, easily, precision can satisfy a requirement basically also, use extensively at a lot of requirements not tall field is met. X4 and X5 two terminal, set by its according to transducer manual proper beforehand after buy, have control transducer to rise fast and fall fast function. SP is watch of electric contact pressure, SP1 and SP2 are the floor level contact of pressure and upper limit contact respectively. Control the state of X4 and X5 directly. Namely, when X4 and CM put through, the output frequency Fx of transducer rises, when disconnecting, fx stops to rise. And when putting through with CM when X5, fx drops, the Fx when disconnecting stops to drop. CNC Milling
