Anonymous users2024-02-10This depends on whether your motors start staggered or all started together; and whether the motor is directly started or equipped with a triangle start or soft start. A 200kW generator can generate about 200* of electricity after deducting the power generation loss.
Staggered start: If the largest motor is below 50kw, the instantaneous current is about 50*3, which can be driven.
If all of them are started together, the instantaneous current of direct start is 3 times, 120*3=360kw; Soft start times, and then taking into account the possible increase of electrical equipment in the later stage, the direct start is about 400kw, and the soft start can be 300-350.

Anonymous users2024-02-09It is possible to stagger the start of each motor one by one, because the instantaneous current is too large when starting.

Anonymous users2024-02-08The power of the generator divided by the efficiency of the generator is the amount of power required by the generator.
The efficiency of the generator can be selected between, with the low value for the small power and the high value for the high power.
The calculation is as follows:
120kw power optional generator.
The power of the generator = 120kw.
Then it is no problem to choose a 200kw generator.

Anonymous users2024-02-07120kw (sum) motor from the power supply current: 120000 (w) 380 (v) = 228 (a).
Current that can be supplied by a 200kw generator: 200000(W) 380 (V) = 303 (A).
**Volume 303 is much greater than demand 228
The 200kw generator can easily cope with all loads.

Anonymous users2024-02-06The 200kw generator set can be used to 160kw according to the national standard, which is enough to cope with the sum of 120kw motors, but the current at the start moment is larger, as the upstairs said it is best to stagger the start.

Anonymous users2024-02-05120 mixing plant, one mechanical running 300 kilowatt generator, is it okay to <> your pro
300 kW generator, can be vibrated with 120 kW motor. The 300kw generator has an hourly power generation capacity and can reach 240 kWh for a long time. Then the generator efficiency of 300kw diesel generator is about 240kw.
Generator efficiency refers to the conversion efficiency of diesel generator sets in the process of converting the heat energy generated by diesel combustion into kinetic energy through the internal combustion engine, and then converting the kinetic energy into electrical energy through electric balls (Marathon, Stanford, etc.). Generally speaking, generator efficiency is. Hungry.
There are certain specifications for concrete batching plants. >>>More
Stirring function (1) Place the rubber sealing ring on the edge of the blade device; (2) Rotate the blade device in the direction of the arrow and connect it to the mixing cup; (3) Put the mixing cup on the motor device, rotate it in the direction of the arrow, and make it secure; (4) Put the ingredients into the mixing cup (the temperature of the ingredients should be lower than 80) 5) Press the lid into the correct position; (6) Put the plug into the lid and add the ingredients to the mouth, rotate it until it is firmly installed, in order to avoid spillage, the plug should be inserted into the lid before starting to stir; (7) Insert the power plug into the socket; (8) Select the desired speed setting and start stirring; (9) To stop stirring, turn the switch to position 0, and do not turn the blender on or off by turning the blending cup. Want to know....
A set of mobile mixing plants will vary according to the model and configuration, generally ranging from hundreds of thousands to seven or eight hundred thousand, and the specific equipment will be subject to the manufacturer, because the quality of the equipment produced by different manufacturers is different, and the production process is different, so the sales will naturally be different.
The 120 type concrete batching plant is a medium and large concrete batching plant, which is made of the main engine of the twin-shaft mixer and the combined batching machine, and the PLD-3200 batching machine is flexible, the storage hopper volume is 20m3*3-5, and the number of bones of the batching machine is 3-5 kinds. Aggregate feeding is carried out by belt conveyor and continuous conveyor. The main engine of HZS120 batching plant uses JS2000 compulsory mixer. >>>More
