Shaoxing County Key Laboratory for Flow Measurement Approved: Measurement Technology Aims at the "Energy Consumption Pain Points" of the Printing and Dyeing Industry to Break the Deadlock Precisely
Recently, the "Key Laboratory for Flow Meter Measurement" in Shaoxing County, which relies on the technological advantages of the Zhejiang Institute of Metrology (hereinafter referred to as the "Zhejiang Institute of Metrology"), has been officially approved for introduction by the Zhejiang provincial bureau. This achievement is the latest practice of the Zhejiang Institute of Metrology in focusing on the needs of local pillar industries and empowering the transformation and upgrading of traditional industries with professional technology. Its goal is directly aimed at the long - standing problems of "high energy consumption and high costs" that have plagued the Shaoxing printing and dyeing industry.
Shaoxing County: The "Capacity Heart" and "Microcosm of Pain Points" of the National Printing and Dyeing Industry
The industrial label of Shaoxing County comes with a "national - level weight". It is not only the largest cluster of the textile industry in the country (home to the globally well - known "China Textile City", where more than ten thousand textile traders are gathered), but also the "number one county" in terms of national printing and dyeing production capacity. The annual output of printed and dyed fabrics in the whole county accounts for one - third of the national total output. That is to say, one out of every three printed and dyed textiles in the country comes from Shaoxing. This dual core status of "market + production capacity" makes Shaoxing's printing and dyeing industry not only the "ballast stone" of the local economy, but also has an impact on the cost and efficiency of the national textile supply chain.
However, behind the huge production capacity lies an unavoidable "energy consumption curse": Printing and dyeing is a typical energy-intensive industry. Fabric dyeing requires high-temperature steam to heat the dyes, and continuous steam supply is needed for drying the finished products. Even wastewater treatment depends on a large amount of industrial water. Figures speak the loudest: For many consecutive years, the total heat supply and consumption in Shaoxing County have ranked first among county-level cities in China. The steam consumption far exceeds that of counties of the same scale, which is essentially due to the strong dependence of the printing and dyeing process on "thermal energy and water resources".
30% cost proportion: Energy consumption has become an unbearable burden for printing and dyeing enterprises
What's even more critical is that energy consumption costs have become a "tightening spell" restricting the survival of enterprises. According to the statistics of the Printing and Dyeing Industry Association of Shaoxing County, the costs of steam and industrial water account for 30% of the production costs of enterprises. This means that for every 100 yuan of profit an enterprise earns, 30 yuan has to be invested in "energy use". In recent years, with the continuous rise of energy prices, this proportion has been quietly climbing. The person - in - charge of a medium - sized printing and dyeing enterprise has calculated an account. For every 10 - yuan increase per ton in the steam price, the annual profit of the enterprise will decrease by nearly 2 million yuan. For the printing and dyeing industry with small profit margins but large sales volumes, this kind of "cost squeeze" directly leads enterprises into a dead - end cycle of "wanting to upgrade but having no money to invest". Without solving the energy consumption problem, transformation and upgrading will be nothing but a "castle in the air".
Flow metering laboratory: Use "accurate data" to connect the link of "cost reduction → upgrade"
The "Key Laboratory for Flow Measurement Instrument Testing" introduced by Shaoxing County is exactly the "technological scalpel" of the Zhejiang Institute of Metrology targeting this pain point. As an authoritative institution in the field of flow measurement in China, the core advantage of the Zhejiang Institute of Metrology lies in its ability to accurately measure and analyze the flow of media such as steam and water - and this is precisely the key prerequisite for printing and dyeing enterprises to "reduce energy consumption and costs".
Specifically, the laboratory will focus on two core directions:
I. Accurately locate "energy consumption loopholes". Through high-precision flow metering instruments, real-time monitoring of the flow data of steam pipelines and water-using equipment in enterprises is carried out to quickly identify "hidden waste" (such as pipeline leakage, no-load operation of equipment, redundant energy consumption in the process, etc.). For example, an enterprise once found through flow data that there was "micro-leakage" in the steam pipeline due to long-term disrepair. This single issue alone led to an annual steam waste of over 500 tons. After the repair, the cost was directly reduced by over 200,000 yuan.
Secondly, promote the "scenario-based innovation" of metering equipment. The high-temperature, high-humidity, and highly corrosive environment in the dyeing workshop places extremely high requirements on the stability of metering instruments. Ordinary instruments may produce errors due to moisture and corrosion. The laboratory will develop more wear-resistant and more accurate flow metering equipment for this scenario, such as "corrosion-resistant electromagnetic flowmeters" and "high-temperature steam vortex flowmeters", and improve the measurement accuracy to within ±0.5% (far exceeding the industry average of ±1%), making the data more reliable.
From "Measurement Tools" to "Industrial Ecosystem": The Deep - seated Value of Laboratories
The significance of this key laboratory goes far beyond "helping enterprises save some money." In essence, it connects the closed loop of "precise measurement → efficient energy utilization → industrial upgrading" through the in - depth integration of metrology technology.
- For enterprises, accurate traffic data can be directly converted into a cost dividend —— the reduced energy consumption costs can be invested in technological transformation (such as switching to low-temperature dyeing processes and installing energy-saving drying equipment) to accelerate the transformation from traditional printing and dyeing to green printing and dyeing.
- For the industry, the laboratory will become an "industrial test field for flow metering technology". The metering equipment developed for the printing and dyeing scenario can reverse - drive the technological iteration of the flow metering industry. For example, the more intelligent "Internet of Things flow meters" (which can upload data in real - time and diagnose faults remotely) can form a virtuous cycle of "demands of the printing and dyeing industry → innovation in metering technology → re - feeding back to the industry".
- For Shaoxing County, this is a crucial step in the transformation from a "county with large production capacity" to a "county with strong technology" —— by empowering with metrology technology, transform traditional industries with "high energy consumption and high emissions" into advantageous industries with "high efficiency and low emissions", and ultimately achieve a win - win situation between "industrial upgrading" and "ecological protection".
In short, this key laboratory for flow metering in Shaoxing County is a typical case of metrology technology "going down to the front line of the industry". It doesn't talk about empty "technical concepts", but directly targets the most urgent "cost - reduction" needs of printing and dyeing enterprises. With accurate measurement data and scenario - based technological innovation, it helps enterprises solve the energy - consumption problems that are "visible but intangible". This path of "aligning technology with pain points and implementing innovation in the industry" may be the "key to break the deadlock" for the transformation and upgrading of traditional industries.
