Removing air from pipes is very important. Here are the keys to detecting and eliminating it. Several signs can indicate the presence of air in the pipes, such as hearing noises, as the air can cause a knocking or clicking sound when passing through valves or system components.
- Pressure Fluctuations: If there is air in the pipes, there may be fluctuations in the system’s pressure, which can affect pump performance or system efficiency.
- Flow Rate Drop: A decrease in fluid flow through the system can indicate air in the pipes, affecting the amount of fluid supplied to the system components.
- Pressure Loss: Air in the pipes can reduce system pressure, making components inefficient.
- Vibrations: Air in the pipes can cause system vibrations, signalling a potential problem.
Why does air form in pipes?
Air can form in pipes due to several factors:
- Pipe Leaks: If there is a leak in the pipe, air can enter and accumulate.
- Pressure Changes: System pressure changes, such as opening or closing a valve or turning a pump on or off, can cause air to accumulate in the pipes.
- Liquid Level Drop in Tank: If the liquid level in a tank decreases, air can enter the pipe through the empty space.
- Drainage System Issues: Obstructions or leaks in the drainage system can allow air to enter the pipes.
- Installation Problems: Incorrect pipe installation can leave empty spaces where air can accumulate.
It is essential to remove air from pipes to ensure proper system functioning and avoid damage to the pipes or system components.
How to eliminate air from pipes
There are several ways to remove air from pipes:
- Use an air vent: an air vent is a device connected to the pipe that allows air to exit the system.
- Use a drain pump: a drain pump is a device connected to the pipe that extracts air and water from the system.
- Opening and closing valves: opening and closing valves at different points in the system can help remove air from the pipes.
- Use a filling device: a filling device is a pump connected to the pipe that supplies fluid to the system, helping to remove air.
- Use an aeration device: an aeration device connects to the pipe and supplies air to the system to eliminate accumulated air.
- Use an air release valve: installing air release valves in high points of the system can prevent the formation of air pockets in a pipe. This reduces air dragged in the water while the system is pressurized.
Another benefit of placing air release valves in the hydraulic system is to introduce air into the drain pipes to maintain atmospheric pressure, preventing collapse and crushing damage to the pipes.
It is important to follow the manufacturer’s instructions when using any of these devices to remove air from pipes. It is also advisable to have a qualified professional perform this task safely and efficiently.
The presence of air in the pipes can cause them to break, especially if the air pressure is very high or if there are pressure fluctuations in the system. The friction and pressure of the air can damage the pipe and cause it to break. Additionally, air can affect system efficiency and cause components to malfunction, leading to pipe damage.
