There is SLI-360；; SLI-900 .
G 1 1S type-adopts elevator special frequency converter produced by Fuji Electric Company.
3)? According to the computer control mode
DIM-MR-MIC microcomputer device includes MMIC and VMIC, which exchange information with each other in serial communication mode through various circuit boards to complete various functions.
CP28X-MMIC, VMIC and various communication functions are integrated in the motherboard (CP28) and interface board, and all parts exchange information with each other through serial communication to complete various functions.
(2) The main components of Fujita elevator are as follows? : (This information is mainly about the project configuration)
1)? Traction machine (worm gear reducer): There are two kinds of traction machines in this project: RA and TM, which are composed of motor, reducer, traction wheel, guide wheel, brake, speed detection device, manual brake release and turning gear. The rotating part is provided with various warning signs, up and down arrows and yellow paint.
2) Traction wire rope: the traction wire rope of this project is Ф12mm× 6.
2.？ Confirm whether the main wire rope and speed limiter wire rope on the car are worn or broken.
When the wear length of steel wire rope φ 12mm exceeds 4mm, or there are many broken strands, a replacement plan shall be made.
3) Control panel
Main components: main computer board CP28, group control computer board CP28, relay interface board IF6 1, frequency converter G1S, #6, #36 main contactors, power board VS 16, and remote monitoring TLM200 board.
4) Door (open horizontally):? Model of door mechanism: DCL-33 split AC variable frequency speed regulation,
Main components: main control board IF78, frequency converter, frequency conversion door machine, transmission mechanism and door leaf, double door knife, door light curtain protection device TL-JONES.
5) Hall door (horizontal):
Model of hall door mechanism: DCL-30 split type, mainly composed of door hanging plate and steel wire transmission device, forced door closing hammer, emergency door lock, door hook lock device, main and auxiliary contacts, door leaf and slider.
6) Guidance system:? Main components: main guide rail 13K, counterweight guide rail 8K, sliding guide shoe (three-piece overshoe liner) and oil cup.
7) Safety device:
①? Speed limiter: throwing block type, switching speed 1 15% rated speed, clamping speed 125% rated speed.
②? Tension device of speed limiter: the action distance of broken rope switch should be greater than 100mm, and the minimum distance from the device to the ground: the step speed of 2.0m/s is 700 ~ 800mm 1.75m/s is 500 ~ 600 mm
③? Safety tongs: progressive safety tongs. The clearance between the safety tongs and the guide rail is 4.0 ~ 6.0 mm. ..
④? Buffer: oil buffer, pay attention to dust and rust prevention, working conditions and buffer distance (150~400mm).
⑤? Terminal limit device: upper forced deceleration switch ls101~104; Press the forced deceleration switch LS20 1~204, and the car hits the bow.
8) Balance compensation chain:
9) Well information device:
Roof sensors: 3IR-3U, 1U, 1D, 3D, shaft floor sensor board, and 3MS proximity switch.
10) weighing device:
Main components: mobile car, weighing rubber, differential transformer.
165438+
In-car control box H 18CB, outgoing call button box H 18BY (single elevator), H 18DG (parallel connection) and H 18BZ (group control) are all in serial communication mode.
12) alarm and fire fighting device:
Alarm button, alarm bell, three-way call (in the car, machine room, property management center or remote monitoring center), fire switch outside the hall.
13)VF drive control: SLI-900 is a special frequency converter for elevators designed and developed by Fujita Elevator Company of Japan and manufactured by Fuji Electric Company. ? Its principle and characteristics are: using high-performance vector control technology, using PWM control method, using high-power gate trigger transistor devices to control the voltage and frequency of AC motor, so as to control the flux and output torque of AC motor. At the same time, because AC voltage can get AC power supply current which is similar to sine wave, the harmonics are minimized, so the power consumption is less.
G 1 1S is a special frequency converter for elevators produced by Fuji Electric Company. The PG card of G 1 1S series inverter used by our company is special for Fujitsu, so the general G 1 1S inverter cannot be interchanged with the inverter used by our company.
Most users who buy Huasheng Fujitec elevators are real estate agents and large shopping malls, and consumers are very cautious about the purchase of elevators. Because elevator accidents and safety performance are generally prone to make mistakes, many people in the world have "swallowing people" or even "falling" time because of the imperfect safety performance of elevators, which has caused harm to people's lives and health. Therefore, when purchasing elevators, we must investigate the safety settings and market reaction of such elevators.
