The piston compressor is a compressor that relies on the reciprocating movement of the piston to pressurize and transport the gas. Is a positive displacement compressor, also known as "reciprocating piston compressor" or "reciprocating compressor". It mainly consists of working cavity, transmission parts, fuselage and auxiliary parts. The working chamber is directly used to compress the gas, consisting of a cylinder, a cylinder sleeve, an air valve, a filler, a piston and a piston rod. Piston driven by the piston rod inside the cylinder for reciprocating motion and working chamber volume on either side of the piston size changes take turns to do the opposite, gas volume decrease side because of the increased pressure through the valve, volume increases on one side of the pressure, reduce the air through the valve inlet gas, driving part to realize reciprocating motion, a crankshaft connecting rod, eccentric slider, inclined plate, etc., Among them, the crankshaft connecting rod mechanism is the most common, which is composed of crosshead, connecting rod and crankshaft Piston Air Compressor,Piston Type Compressor,Piston Compressor,Oil Free Piston Compressor Yangzhou Mustang Air Compressor Co. , Ltd , https://www.aircompressor-ym.com
Guo Weizheng said that the current Municipal Heating Supply Association, together with the Municipal Construction Committee and the Municipal Quality Supervision and other departments, conducted a dynamic review of the heat meter on the market and recommended 20 heat meters that meet the standards for the heating unit. For the issue of heat metering for which heat metering has been implemented, the “low-to-high-to-high†policy will continue to be implemented. If the heating fee is calculated on the basis of the residents' heating area, the area fee will be charged. If the heat metering method is used to calculate the amount of heat for the residents, The charge based on heat metering will not increase the burden on residents' heating.
By the end of the "Twelfth Five-year Plan," the city's heating area will reach 850 million square meters, and a new 220 million square meters of heating area will be charged according to heat metering. It is understood that the Municipal City Council will also buy hot cards in the city's residential community pilots. In the future, citizens can buy their own heat as if they were buying electricity.
Beijing will continue to promote the reform of thermal measurement. Guo Weizheng, director of the Municipal Heating Supply Office, recently introduced that residents' existing buildings will charge over 10 million square meters of space in accordance with heat metering, and all new buildings will be charged according to heat metering. The charging policy continues for the previous year's "Low is not high"
