The maximum pressure resistance of the factory gas source pressure gauge varies depending on the application scenario, medium type and industry specifications. The following is a specific analysis:
petrochemical industry:
according to Code for Design of Instrument Gas Supply in Petrochemical Industry (SH/T 3020-2013), the pressure range of outlet header of gas source device is 600 kPa(G)~1 MPa(G) the pressure at the input of the instrument varies according to the type of equipment. 140 kPa(G)~600 kPa(G) between.
stationary pressure vessel:
according to the Safety and Technical Supervision Regulations for Stationary Pressure Vessels (TSG 21-2016), the limit value of the scale of the pressure gauge dial shall be the working pressure. 1.5~3.0 times.
By comprehensively considering the medium type, pressure range, environmental conditions and industry standards, the factory air source pressure gauge can be reasonably selected to meet the requirements to ensure the safe and efficient operation of the equipment.
Screw air compressor and scroll air compressor are common compression equipment, they have their own characteristics and applicable scenarios. The following is a detailed comparison of these two air compressors: screw air compressor working principle: screw air compressor is through the main-slave screw machinery
Today, with the rapid development of science and technology, the precision and performance requirements of laboratory equipment are increasing day by day. Among them, the air compressor as a laboratory commonly used gas compression equipment, the stability of its performance and the purity of the gas quality for the accuracy of the experimental results have a crucial
In the field of modern industry, as an important energy conversion device, compressor is widely used in various gas compression and transmission occasions. Especially for the special field of coalbed methane, the demand of medium concentration coalbed methane compressor is increasing. At the same time, with the ring
Analysis of the application of air compressors in the die casting industry As one of the core areas of modern manufacturing, the die casting industry focuses on precision filling of liquid or semi-liquid metal into the mold cavity through high-pressure technology, and forming high-precision castings after cooling and solidification. This process is extensive.
The noise problem of the dry oil-free screw machine can be described from the following aspects: Noise level: The dry oil-free screw machine does produce a certain amount of noise during operation, but the size of the noise will be affected by many factors. Generally speaking, the screw machine
Scroll compressors and screw compressors are two different types of compressors with different operating principles and characteristics. The working principle of the scroll compressor is to use the rotating motion of the scroll to realize the compression of the gas. It has a simple structure,
Q: air consumption of equipment and air compressor selection? Answer: according to the air consumption of equipment to choose air compressor first consider two points: 1, the pressure problem, need to understand the normal use of all equipment pressure range, take the maximum and minimum, and then according to the maximum increase of 1kg pressure to select the air compressor.
Air compressor output with water, you can take the following measures to solve: check the drainage system: to ensure that the air compressor drainage system is working properly, check whether the drainage valve is open, the drainage pipe is unblocked, in order to remove the condensate in time. Adjust pressure dew point
When discussing the air supply pressure of the air compressor, we need to pay attention to its normal fluctuation range to ensure the stable operation of the equipment and the smooth progress of production. The normal fluctuation range of air supply pressure of air compressor is an important technical parameter, which is affected by many factors, including air
The screw machine can be oil-free. For example, oil-free screw air compressor is the use of oil-free lubrication technology, not in the compressed air to the air oil. This type of oil-free screw machine is particularly suitable for applications that require high compressed air quality, such as food and pharmaceutical industries
