Learn Devices and Accessories for Safety of Air Storage Tanks
On this page
Air storage tanks are indispensable components in air compressor systems, tasked with storing and supplying compressed air reliably. Installed outdoors, these air storage tanks receive air pressurized by compressors and distribute it through pipelines to various points of use, ensuring the system operates reliably under diverse working conditions.
Protective Devices for Air Storage Tanks
Protective devices for air storage tanks are essential to ensure their safe and reliable operation in air compressor systems. Here are key protective devices commonly employed.
1. Temperature Control Device
Internal temperature within air storage tanks must be regulated with a temperature control device, ensuring it stays within safe limits (typically below 120°C). When temperatures exceed the set limit, this device automatically cuts power and sounds an alarm to prevent safety incidents caused by high temperatures.
2. Drainage System
Compressed air contains moisture, which condenses into water as it cools within the air storage tank. Failure to promptly drain this water can affect the quality of compressed air and lead to internal corrosion. Therefore, the tank's bottom is equipped with a drain valve for regular water discharge, maintaining dryness and cleanliness inside the tank. The drainage system typically includes manual switches and solenoid valves to ensure automatic operation under normal conditions, preventing issues from accumulated moisture.
3. Pressure Relief Valve
Positioned on the tank's outlet pipeline, a pressure relief valve releases pressure automatically when system pressure exceeds a set value, typically 1.25 to 1.4 times the maximum operating pressure of the air compressor. This protects the system from excessive pressure, ensuring safe and stable operation.
4. Oil Separator
During compressor operation, lubricating oil often accompanies compressed air into the air storage tank. To prevent oil from entering the gas system and affecting final product quality, air storage tanks are usually equipped with oil separators. These devices effectively remove lubricating oil from compressed air, maintaining air purity and system reliability.
5. Explosion-proof Device
Particularly in specific industrial environments like chemical plants or facilities handling flammable gases, explosion-proof devices for air storage tanks are crucial. These devices rapidly release pressure if internal pressure rises abnormally, preventing explosions and safeguarding surrounding environments and personnel.
Safety Accessories for Air Storage Tanks
Safety accessories for air storage tanks are crucial components that ensure safe operation and maintenance of these tanks within air compressor systems. Here are important safety accessories typically utilized.
1. Safety Valve
Primarily, safety valves release pressure promptly in case of abnormal conditions such as excessive pressure or failure of pressure controls in the compressor system, preventing tank explosions due to high pressure. Selection and installation of safety valves should align with the system's maximum operating pressure, with regular calibration and testing to ensure sensitivity and reliability.
2. Pressure Gauge
Used to display the internal pressure of the air storage tank, the accuracy of pressure gauges directly influences operators' judgments and control over system operation status. Pressure gauges require annual calibration to ensure accurate readings, with immediate replacement upon detection of damage or inaccuracies.
3. Liquid Level Indicator
Monitors the liquid level inside the air storage tank, especially critical in applications requiring precise liquid level control and management. Liquid level indicators promptly detect abnormal changes in liquid levels, aiding operators in taking necessary actions such as timely drainage or adjustment of operational parameters to maintain system stability and safety.
4. Temperature Gauge
Monitors internal temperature changes within the air storage tank, ensuring temperatures remain within limits that materials can withstand. Temperature gauges help prevent safety incidents caused by high temperatures and serve as crucial references for maintenance and inspection.
In conclusion, air storage tanks play a crucial role in ensuring the safe and stable supply of compressed air in air compressor systems. By appropriately configuring and correctly using protective devices and safety accessories, the safety, reliability, and operational lifespan of air storage tanks can be effectively enhanced, ensuring continuous and stable operation of compressed air systems under various working conditions. Regular inspection, maintenance, and management of air storage tanks are key measures in ensuring the efficiency and safety of the entire compressed air system.
