The pressure charging system operation principle of magnetic suspension blower fan of the present invention is: first stop valve 28 and draining valve 29 are closed, and starts
Magnetic suspension blower fan 1, low-pressure air enters air accumulator 27 through initial check valve 4, and bi-bit bi-pass proportion magnetic valve 3 controls to put
The aperture of empty valve 2 makes pressure and discharge relation correct position between surge line and mistake hot line, the magnetic of magnetic suspension blower fan 1
Suspension blower fan 1 steps up rotating speed, makes the pressure of pipeline increase, and when pressure is more than 0.8bar, sequence valve 5 is opened,
Gas through two-position five-way the first magnetic valve the 6, second magnetic valve 7, the 3rd magnetic valve 8 respectively enter the first pressurized cylinder 9,
The right-hand member of two pressurized cylinder the 10, the 3rd pressurized cylinders 11, owing to the area of the big piston of pressurized cylinder is that 5 times of valve piston are
(A1=5A2), so gas push piston is moved to the left, piston during movement by the air in left end cavity
Compression also enters air accumulator 27 through first left check valve the 19, second left check valve 23 of left check valve the 21, the 3rd, works as piston
When arriving left end stroke, first magnetic valve the 6, second magnetic valve the 7, the 3rd magnetic valve 8 obtains electric commutation, and gas push is lived
Plug moves right, piston by gas compression in right end chamber body and through first right check valve the 18, second right check valve 20,
Three right check valves 22 enter air accumulator, when piston arrives right-hand member stroke, and first magnetic valve the 6, second magnetic valve 7, the
Three magnetic valve 8 dead electricity commutations, gas push piston is moved to the left again, and pressurized cylinder moves and so forth, until piston stress
Balance i.e. P1A1=P2A2, because A1=5A2, so P2=5P1, P2 are air accumulator 27 pressure, P1 is magnetic suspension
Fan outlet pressure 1.2bar, so, now air accumulator 27 pressure is 6bar.When air accumulator 27 pressure reaches 6bar
Pressure transmitter 25 provides the signal of a 4-20mA, and magnetic suspension blower fan reduces rotating speed until shutting down, when air accumulator 27
When pressure drops to 4.5bar, pressure transmitter 25 provides the signal magnetic suspension blower fan 1 of a 4-20mA and starts, gas
Boosting promotes first pressurized cylinder the 9, second pressurized cylinder the 10, the 3rd pressurized cylinder 11 action compresses air, makes air accumulator 27
Pressure rises to 6bar again, then shuts down.
The pressure source of the pressure charging system of magnetic suspension blower fan of the present invention uses magnetic suspension blower fan, it is not necessary to drive disk assembly, is also not required to
Want common mechanical bearing, reduce lubrication, improve efficiency, easy to maintenance
The pressure charging system of the magnetic suspension blower fan of the present invention can obtain the source of the gas of high pressure in magnetic suspension blower fan system.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art
