Installed Power and Electricity Use in a Block Factory: What Is the Difference?
Installed power tells you which equipment loads belong in the electrical design. Metered electricity tells you what a factory consumed. These are different figures: HENGDE's 200 m³ two-shift standard proposal lists 154.75 kW of equipment power, not 154.75 kWh per cubic metre or a guaranteed continuous demand.
The three units a block-factory buyer needs
| Unit | What it answers |
|---|---|
| kW | What is the listed equipment power or measured demand at a particular operating condition? |
| kWh | How much electrical energy was used during a defined period? |
| kWh/m³ | How much metered energy corresponds to each cubic metre of the defined output? |
A 22 kW mixer does not consume 22 kWh merely because it is installed. Its energy use depends on running time and operating load. Likewise, the sum of equipment ratings is not a reading from the factory meter.
Where the listed 154.75 kW comes from
The standard proposal groups its equipment power as follows. It covers the stated configuration, including physical foaming, a horizontal mixer and a two-direction rotary cutting system.
| Equipment group | Listed power |
|---|---|
| Feeding and metering | 14.85 kW |
| Foaming, mixing and compressor | 44.50 kW |
| Demoulding, peeling and body stacking | 34.50 kW |
| Rotary cutting | 31.90 kW |
| Finished-product palletizing | 6.20 kW |
| Transfer and conveying | 22.80 kW |
| Total listed equipment power | 154.75 kW |
The complete factory equipment guide identifies the proposal’s two-shift, 16-hour cutting-volume basis and supply scope. Do not multiply the total by sixteen hours and call the result the factory’s expected daily consumption. Some machines cycle; others wait for an upstream or downstream operation.
Additional local pumps, lighting, offices, handling equipment or optional packing systems also need to be identified. Use the final equipment schedule, not an illustrative table for another configuration, when preparing the electrical design.
Size the supply from the operating sequence
HENGDE provides the selected equipment loads and control sequence. The site electrical designer uses them with the local voltage, frequency, motor-starting conditions and applicable installation requirements. Installed kW alone does not select the transformer, incoming cable or protective devices.
Map which equipment runs together. For example, mixing and casting follow their batch sequence while cutting works on bodies prepared earlier. Identify the connected auxiliaries and restart sequence as well as normal running. This is how the electrical plan follows the real production line instead of treating every motor as one continuous load.
Calculate consumption from matched meter and output records
Period energy = closing meter reading − opening meter reading.
Specific electricity use = period energy ÷ accepted product volume for the matching production scope.
Illustrative example: assume a production meter rises from 12,400 to 13,000 kWh over eight hours. Energy used is 600 kWh, and average demand over that period is 600 ÷ 8 = 75 kW. If the matching accepted volume is 150 m³, the result is 4 kWh/m³.
If the same period had 180 m³ of cast volume, dividing by cast volume would give 3.33 kWh/m³. The lower number would reflect a different denominator, not a more efficient machine. These assumed figures are a calculation example, not a HENGDE consumption test or performance promise.
Where bodies cast on one shift are cut and inspected later, link readings to batch records and use a production period that captures the intended stages. Avoid dividing today’s electricity by yesterday’s finished output without explaining the difference.
Find out why the number changed
- Check the boundary first. Was a compressor, pump or new packing stage added to the meter?
- Check utilization. More cleaning, trial running or waiting can raise energy per accepted cubic metre even without a higher running demand.
- Check product losses. Additional rejects reduce the denominator while the factory still uses energy to process them.
- Compare like with like. Keep product size, density, recipe, shift length and included stages identifiable.
Use this baseline before claiming an energy-saving percentage. A useful improvement reduces metered energy for the same accepted production scope or increases accepted output without an equivalent energy increase.
