What is the Purpose of a Hydrophore Expansion Tank?
The expansion tank, also known as a balance tank, plays a critical role in hydrophore systems by maintaining system pressure within stable limits. It prevents the hydrophore from frequently switching on and off during low water consumption, thereby ensuring system stability. Using an expansion tank reduces the motor's switching frequency (how many times the motor starts and stops per hour), which in turn extends the system's lifespan and improves efficiency.
Expansion tanks are generally produced in two types: air-cushioned and diaphragm. In air-cushioned models, there is no clear separation between water and air. As a result, some of the pressurized air mixes with the water, requiring replenishment by a compressor or an air charging unit. In diaphragm tanks, water and air are separated by a flexible diaphragm (membrane), preventing air loss and eliminating the need for an air charging unit or compressor. Due to these advantages, diaphragm tanks are more commonly preferred today.
Selecting the correct tank capacity is also crucial for optimal system performance. The tank's capacity should be determined based on the system's water demand and pressure fluctuations. An undersized or oversized tank can lead to undesirable outcomes in the system. Additionally, regular maintenance and inspection of expansion tanks support long-lasting and efficient system operation.
From an energy efficiency standpoint, expansion tanks play a significant role. By reducing the hydrophore's operating frequency, they contribute to energy savings and lower operating costs. Especially in large facilities and industrial areas, the correct use of expansion tanks can lead to substantial energy savings.
In conclusion, expansion tanks are indispensable components for ensuring stable, economical, and long-lasting operation of hydrophore systems. With proper selection and regular maintenance, maximum efficiency can be achieved in the system.
