Among them, 54 million sets are required for the power sector and 6 million sets for other sectors. From the perspective of product structure, there are 48 million electric energy meter products, 7 million electric energy meter products, 2.5 million portable electric meters, 1.5 million digital instruments, and 1 million other meter equipment.
The demand structure of various types of products is also changing. The proportion of electronic energy meters in electric energy meter products will gradually increase from the 2 million units in the early period of the “10th Five-Year Plan†period to 12 million units in the final stage. The technical content of installed meters, portable meters, and digital meters will also increase, and product levels will continue to increase. Therefore, although the total annual product demand will not change much in recent years, the total sales volume will continue to increase, and the annual growth rate is expected to be 8%.
Screw Air Compressor (working principle) :
Screw compressor is a volumetric gas compression machine with working volume for rotary motion. The compression of gas depends on the change of volume, and the change of volume is achieved by the rotary motion of a pair of rotors in the housing of the compressor. Basic structure: in the body of the compressor, a pair of helical rotors are arranged in parallel to each other. Usually, the rotor with convex teeth outside the section circle is called the Yang rotor or Yang screw. The rotor with concave teeth in the section circle is called Yin rotor or Yin screw, a Yang rotor is connected with the prime mover, driven by the Yang rotor Yin rotor rotor rotation on the last pair of bearings to achieve axial positioning, and bear the axial force in the compressor. Cylindrical roller bearings at both ends of the rotor enable the rotor to achieve radial positioning and withstand radial forces in the compressor. At both ends of the compressor body, a certain shape and size of the orifice are respectively opened. One for inhalation, called the air inlet; The other is used for exhaust, called exhaust port.
Product advantages:
1. Screw air compressor works smoothly, has small vibration and low noise compared with piston machine.
2, oil and gas separator: filter material, high efficiency, air oil content rate is less than 2ppm.
3, controller: operation and related data are displayed on the control panel, easy and convenient operation.
4, spraying lubricating oil with sealing, cooling, noise reduction and lubrication.
5, high stability, high efficiency, small vibration, low noise advantages.
6. Good heat dissipation system. Adopting plate-fin structure and material, the cooler has high pressure resistance, high heat dissipation efficiency and good corrosion resistance.
7, Air Filter: heavy duty, multi-stage air filter, large working face.
