Summary
What size generator do you think is required to keep this machine running stably?
Case: The parameters of the WP315A hydraulic butt fusion welding machine are as follows: milling cutter power 2000W, heating plate power 3100W, hydraulic station power 750W, 50HZ, 220V. (Customization is required for other voltages or frequencies.) What size generator do you think is required to keep this machine running stably? 1. First, let's get familiar with some parameters of the generator, including model, frequency, voltage, rated power, maximum power, rated current and power factor — these are several extremely critical metrics. 2. Case generator: Model LC10000D-DC, frequency 50HZ, voltage 220V, rated power 7000W, maximum power 7700W, rated current 31.8A, power factor 1.0. Then let's calculate: first, we need to note that 50Hz (matched), 220V (matched), rated power 7000W (matched), and maximum power 7700W (unmatched). The complete machine will reach a maximum power at the very beginning of its startup. The milling cutter is equipped with a motor, and the required maximum power ranges from 5000W to 6000W. Heating plate without motor, requires 3100W. The maximum power of this generator, which is 7700W, is completely insufficient. Therefore, the moment the PE hydraulic butt fusion welder is started, certain electronic components will be damaged due to the insufficient maximum power. So what size generator is required for the WP315A machine? The answer is that the minimum standard for this generator is a voltage of 220V, a frequency of 50Hz, a rated power of 10000W, and a power factor of 1.0. If the power factor is 0.8, then the rated power needs to be above 12.5KW. The model numbers listed above do not represent the power output of the machines.Pe Butt Fusion Welding Machine and Generator
The hydraulic station has a motor and requires a maximum power of 1500W-2250W.
