The current operating current of the main pump is 24A, then the operating cost of one year is: 12KW × 20h × 340 days × 0.7 yuan /KWh0.85 = 48552 yuan One year running cost after transformation by VLT frequency is: 12KW × 50% × 50% × 50% (the flow is 50% of the original design flow; the relation between flow and power is the third power) × 20h × 340 days × 0.7 Yuan / Kwh = 7140 Yuan. One year saves money: = 41412 yuan The initial investment of this project is 22,000 yuan, the benefit is very significant. According to the above principle, in 2002.6 ~ 2003.9 a total of five dyeing machines, an overflow sub-drift machine was transformed to transform the total power transformation 112 KW. Conservative calculation can save 270,000 yuan. (Initial investment of 135,000 yuan). The main power parts, hydraulic parts and electrical parts of Tower Crane are imported brands, which fully meet the safety standards of European and American industries and ensure safe, stable and efficient operation;It has multiple security protection functions, which makes the operation safer and more convenient; Large Wind Power Generation Tower,Large Wind Power Crane,Wind Power Lifting,Large-Scale Luffing Tower Crane Jinan Shanghangda Machinery Co., Ltd. , https://www.jnwoodmachine.com
(MK8C-1LT high-temperature dyeing machine, for example)
With the intelligent one button extension / retraction, the whole vehicle can be disassembled and disassembled in a shorter time, and it can reach the working state quickly; the short-distance transfer is convenient and efficient
Energy Saving Analysis of Main Pump Frequency Conversion in Dyeing Machine
Dyeing machine, overflow sub-bleach main pump role is to produce a certain pressure and flow of water and through the nozzle to promote the cloth cycle. Different weights of cloth need to be different pressure and flow of liquid flow to promote this adjustment is now by adjusting the pump outlet valve to achieve, we are now the weight of the cloth at the end, so the valve opening only 30% About 80% of the energy is wasted at the valve according to the fluid mechanics and pump characteristics.
