The calculation of air compressor displacement and equipment gas consumption should be combined with theoretical formulas, measured data and system matching principles. The following is a step-by-step guide:
piston air compressor:
d: cylinder diameter (m),S: piston stroke (m),n: speed (r/min)
& eta; capacity: volumetric efficiency (0.85-0.95)
screw air compressor:
consider temperature, pressure, leakage, etc:
Q real = Qth×P suction p row ×T row t suction × & eta; Temperature rise × & eta; Machinerydirect measurement method: Use vortex flowmeter or thermal mass flowmeter to measure instantaneous flow and take statistical average.
Formula calculation:
peak flow method:
redundant design:
pressure loss correction:
it is recommended to dynamically match the original performance curve of the air compressor with the load curve of the gas equipment, and if necessary, use the variable frequency air compressor or install the energy recovery device to optimize the system energy efficiency.
The replacement cycle of the air compressor oil filter will be affected by many factors, including the quality of the oil filter and the use environment of the air compressor. Generally speaking, the service life of the better quality brand oil filter can reach 3000 hours, while the service life of the general quality oil filter may only be
When choosing a permanent magnet variable frequency air compressor, you cannot rely solely on the brand, but also need to consider the actual needs and budget, so as to choose the appropriate model and specifications. Shanghai Granklin Group also produces permanent magnet variable frequency air compressors, which use high-efficiency permanent magnet synchronous motors.
Oil-free air compressor is widely used in many occasions because of its unique characteristics and advantages. The following are some of the main applications of oil-free air compressors: University laboratories: pure, oil-free compressed air is often used in the laboratory to ensure the experimental results
An air pressure vessel, or pressure vessel, is a device used to store and transport gas, liquid or steam. It bears the pressure of the internal medium and ensures safe operation. Its standard service life is generally 15 to 20 years. This is in accordance with relevant national standards and
The exhaust oil content of micro-oil screw air compressor is a key performance index, which directly affects the use effect of air compressor and the safety of subsequent equipment. The following is a detailed explanation of the exhaust oil content of the micro-oil screw air compressor: the standard of oil content: 1
What is the difference between micro-oil air compressor and oil-free air compressor? At present, oil-free air compressor is improved and developed on the basis of oil air compressor. There are two main ways: one is to use water instead of oil, and the other is to coat the rotor with a self-lubricating coating.
The air consumption of a low-pressure air compressor depends on many factors, including the power of the air compressor, the exhaust pressure, the exhaust temperature and the exhaust flow rate. The following are some considerations about the air consumption of low-pressure air compressors: the relationship between power and air consumption: in general, air
The application possibility of micro-oil air compressor in the production of raw materials is analyzed as follows: the characteristics of 1. micro-oil air compressor micro-oil air compressor adopts the mixing mode of lubricating oil and air, and separates lubricating oil and air through oil and gas separator, so as to realize the air
The amount of compressed air used in the chemical process covers many aspects and needs to be calculated comprehensively according to the specific process flow, equipment requirements and production scale. Its core components include process gas consumption, equipment drive gas consumption, instrument control gas consumption, purging and cleaning.
The pressure of the air compressor is usually determined according to the specific application requirements and will be affected by the use environment and equipment specifications. Generally speaking, the pressure of air compressor can be divided into the following ranges: low pressure air compressor: working pressure is usually between 0.7 and 1.2 M
