Description
Technical Field
The invention relates to the technical field of air source processing devices, in particular to a large-diameter air source processing device.
Background
The air source processing device is an air filter, a pressure reducing valve and an oil atomizer, belongs to components in an air pressure traditional system, is an indispensable air source device in most pneumatic systems, is arranged near pneumatic equipment and finally guarantees the quality of compressed air.
The air filter is used for preventing the compressed air from flowing out of the air source from containing excessive water vapor and oil drops, and simultaneously containing solid impurities such as rust, sand grains, pipeline sealant and the like, which can damage a piston sealing ring, block small exhaust holes on components and parts, and shorten the service life of the components and parts or make the components and parts invalid. The air filter is used for separating liquid water and liquid oil drops from compressed air and filtering out dust and solid impurities in the air, but cannot remove gaseous water and oil.
The pressure reducing valve has the function principle that the water pressure is reduced by the local resistance of the flow passage in the valve to water flow, and the range of the water pressure drop is automatically regulated by the water pressure difference of an inlet and an outlet at two sides of a membrane or a piston connected with a valve clack. The constant-ratio pressure reduction principle is that the water pressure ratio of a floating piston in a valve body is utilized to control, and the pressure reduction ratio of an inlet end and an outlet end is in inverse proportion to the area ratio of the inlet side and the outlet side. The pressure reducing valve works stably without vibration; the valve body is not provided with a spring, so that the valve body is not corroded and has no worry about metal fatigue failure; the sealing performance is good, leakage does not exist, and therefore, the dynamic pressure (when water flows) and the static pressure (when the flow rate is 0) are reduced; in particular, the water flow is not influenced while the pressure is reduced.
Although the water flow has great head loss through the pressure reducing valve, the water flow is still energy-saving on the whole because the waste of water is reduced, the flow distribution of the system is reasonable, and the layout and the working condition of the system are improved. When the medium is steam, a pilot piston type pressure reducing valve or a pilot bellows type pressure reducing valve is preferably selected. The pressure relief valve should generally be installed on a horizontal pipe for ease of operation, adjustment, and maintenance.
The function of the oil atomizer is that in a pneumatic fluid transmission system, power is transmitted and controlled through compressed air in a closed loop. Where the air medium requires lubrication, an oil mist device is a component designed to add the required lubricant to the air stream. The oil atomizer is a special oil injector, which atomizes the lubricating oil and injects it into the air flow, and then flows into the parts to be lubricated along with the compressed air, so as to achieve the purpose of lubrication.
Air supply processing apparatus generally installs on the compressed air pipeline, and the device's effect is impurity and moisture aluminum alloy in the filtration compressed air, and compressed air pipe joint is just so done, and in addition, air supply processing apparatus also installs on equipment, and gas is to the lubricated effect of filtration, and the heavy-calibre air supply processing apparatus on the existing market is through adding the coupling and connecting, adds the coupling and connects easy gas leakage, does not master the symmetry well.
