Description:
  SC200/200V construction lift, is designed and manufactured by Baoliang Construction Machinery Factory according to GB/T10054-2005 "construction lift" design and manufacture of a gear, rack drive, frequency conversion circuit to control low-speed double-speed vertical transport machinery.
1. Description of the preparation of product model
产品型号说明
The model of the lift is composed of group, type, characteristic, main parameters, variant update, characteristic and so on.
The picture is as follows.
2. the technical performance characteristics of the product.
1 the maximum erection height of the lift is 150m, the maximum lifting speed is 36m, the whole machine runs smoothly, the noise is low, the maintenance is convenient, the gear and rack meshing is accurate and stable, and the service life is long.
(2) the transmission system adopts external double-drive double-enveloping toroidal turbine worm drive mechanism, the professional manufacturer is matched as a whole, and the performance is more stable.
(3) the guide rail frame is made of large cross-section standard section (section center 0.93m × 0.93m) and main chord φ 76 high strength seamless tube, which is stronger than that of the same industry, and has better safety and anti-overturning stability.
(4) the cage is designed with wide cage (shape width 1.5m), which is more spacious in construction.
(5) the door body and the enclosure of the cage are made of punched galvanized steel plate, which is beautiful and generous, and the cab is equipped with toolbox, electric fan, mobile phone charging, water cup seat and so on.
(6) the whole machine is equipped with all kinds of safety devices and overload protection devices, high safety performance.
(7)the variable frequency lift not only has all the technical characteristics of the above SC200/200 (ordinary) construction lift, but also has the unique advantages of the variable frequency construction lift itself:
The energy saving effect is remarkable and the use cost is low.
As shown in the table below.
Taking SC200/200 and SC200/200V as examples, the performance comparison table of ordinary and variable frequency lifts is given.

Taking SC200/200 and SC200/200V as examples, the performance comparison table of ordinary and variable frequency lifts is given.
Note: only according to the working state of the single cage of the construction elevator, the whole machine should be twice as much as it.

Comparison item 1: full load start current
200A~300A < 65A
Because the instantaneous power supply current can reach 200ADC 300A at full load, the voltage drop of instantaneous power supply line increases, and the requirement of power supply voltage is strict. Because the power supply current at the moment of starting at full load is less than 65A, it almost does not cause the voltage drop of the power supply circuit, and the requirement of power supply voltage is low.
Comparison item 2: comparison of measured energy consumption
Model Rising current Descending current Total current of one cycle Daily power consumption(10h) Monthly power consumption(30day) Monthly electricity consumption
SC200/200 60A 60A 120A 228KWh 6840 6840rmb
SC200/200V 60A 2A 62A 118KWh 3540 3540rmb
The rising working current is 60A at full load and the working current is 60A when descending. The total amount of electricity used in one day (10h) is 228KWh. the electricity charge of one month (30 days) is about 6840 yuan (1 yuan / kWh), which consumes a lot of energy. The rising working current is 60A at full load and the working current is 2A when falling. The total amount of electricity used in one day (10h) is 118KWh. the electricity charge of one month (30 days) is about 3540 yuan (1 yuan / kWh). The effect of energy saving is remarkable.
Energy consumption comparison results: the whole low-speed variable frequency elevator saves 6600 yuan per month than the ordinary one.
Comparison item 3: comparison of service life of vulnerable parts
General service life Longer service life
Due to the large impact vibration of start-up, operation and braking, the wear degree of vulnerable parts such as roller, gear and brake friction disc is large, so it should be checked regularly and replaced in time. Because of the stable start-up, operation and braking, the fragile parts such as rollers, gears and brake friction plates are more durable, and the braking process has reached the braking target by releasing the kinetic energy generated by the braking of the motor by the braking torque generated by the frequency converter and the motor.
The wear of brake friction disc is small.
Comparison item 4: comparison of work efficiency
Type number operational speed Work efficiency
SC200/200 The running speed is always 33m/min. Lower
SC200/200V The running speed is self-adjusted according to the deadweight, and the speed range is 0~36m/min. Higher
The frequency converter has a perfect protection function, and it is not easy to break down.
The frequency conversion elevator is a two-speed regulation, and the running speed is self-adjusted according to the different load, so the working efficiency is higher.
