Zhejiang Metrology Institute independently develops advanced equipment to meet the stringent test standards for gas meters

<

[ Instrument Network Instrument Development ] Recently, the durability test device for the domestic membrane type gas meter cycle method independently developed by the Institute of Metrology of Zhejiang Province was officially put into use. The device can provide 450,000 gas meter cycle operation cycles, control the maximum temperature change not to exceed ±10 °C, and the maximum pressure change does not exceed ±300 Pa, which fully meets the stringent requirements of the durability test in the new national standard of Membrane Gas Meter.
The new version of the national standard "membrane gas meter" refers to the EU standard, based on the international recommendations OIML R31 and R137:2012, fully consider the development trend of gas meter digitalization and intelligent technology. In order to ensure the synchronization of technical indicators and test methods with the international, higher requirements are imposed on the detection technology of the gas meter industry. The new national standard was released in May this year and will be implemented by the end of the year. Zhejiang Province is the main gathering area for domestic gas meter manufacturers, and it is extremely urgent to adapt to the new national standard.
The Institute of Metrology of Zhejiang Province participated in the drafting unit as the new national standard for membrane gas meters. It is problem-oriented and actively studied EU labeling and international recommendations in the early stage, keeping up with relevant requirements. At the same time, in the new version of the membrane gas meter national standard approval process, the fastest response to the gas meter enterprises to detect the latest performance indicators, organize scientific research, research and development testing equipment.
The commissioning of new equipment will provide technical support for the high-quality development of the gas meter industry, and will also play an active role in promoting the transformation and upgrading of the gas meter industry in Zhejiang Province and improving its quality.

Asphalt Mixing Plant

Asphalt mixing plant is one of the key equipment for road construction. It is mainly used in the production of asphalt mixture for paving road surfaces. Asphalt mixing plant consists of a number of parts, including dosing system, dryer, agitator, dust removal system, fuel system and so on.

The batching system is one of the core parts of Asphalt mixing plant. It is responsible for adding various raw materials to the blender in a certain proportion. These raw materials include asphalt, sand, gravel and other additives. The batching system usually consists of a weighing sensor, a batching bucket and a batching transfer device.

The dryer is another important part of the Asphalt mixing plant. It is mainly used for drying raw materials such as sand and stones. There are heating elements and rotating agitators inside the dryer, which can make the raw materials fully heated and mixed evenly.

Mixer is one of the core parts of Asphalt mixing station. It is responsible for mixing various raw materials together to produce a high quality asphalt mixture. The agitator usually consists of multiple mixing blades, which can fully mix the raw materials to ensure the stable quality of the asphalt mixture produced.

Dust removal system is one of the important components of Asphalt mixing plant. It is mainly used to collect dust and exhaust gases generated during the production process. The dust removal system is usually composed of multiple filters, which can effectively filter out dust and exhaust gas to ensure a clean working environment and air quality.

Fuel system is one of the key parts of Asphalt mixing plant. It is responsible for providing the fuel to power the Asphalt mixing plant. The fuel system usually consists of a fuel pump, a fuel filter and a fuel injector.

Asphalt mixing plant is a kind of high efficiency asphalt mixture production equipment, widely used in road construction field. It has the advantages of high automation, high production efficiency, stable product quality and so on, and provides a strong support and guarantee for road construction.
