Understanding the Role and Benefits of Pressure Tanks in Firefighting Systems

In modern firefighting systems, the pressure tank (also known as an expansion or stabilizing tank) plays an essential role. By storing pre-pressurized water, it helps maintain constant pressure within the pipeline system, ensuring the system remains in a ready state during standby conditions. This significantly improves response time and reduces the frequency of main pump startups.

As seen in the provided image, this pressure tank is built with high-strength steel and coated with anti-corrosion paint, delivering excellent pressure resistance and durability. It features an internal bladder or diaphragm structure with high elasticity, capable of withstanding frequent pressure fluctuations while offering long service life and minimal maintenance needs.

This unit is widely used in fire protection water supply systems, especially for automatic sprinkler systems and hydrant networks, effectively preventing malfunctions caused by pressure instability.

    Fire pumps are a type of pump used in fire fighting. Compared to ordinary pumps, fire pumps have higher standards and requirements in terms of sealing, corrosion resistance and operational efficiency. Before running the fire pump equipment, we need to discharge the gas inside the pump, do you know what is the significance of doing so? The following is the answer from Shanghai Xizhiquan.

    1. If there is gas inside the fire pump, then the equipment cannot form a sufficient vacuum during operation, resulting in the liquid not being able to be sucked up. This phenomenon is called gas binding, and is a phenomenon that often results from many operators not understanding this operation.
    2, understand the formation of gas binding causes, we will understand how to avoid this problem occurs. Before the fire pump equipment is started, the pump casing needs to be filled with liquid. In the pump suction pipe mouth need to be equipped with a non-return valve, can effectively avoid the pump in the liquid due to gravity into the low tank, if the pump position is low, there is no need to carry out filling the pump.
    3. The compressed gas inside the fire pump will occupy a certain space in the fire pump, making it impossible to seal it.

    Therefore, the operation of deflating the fire pump before putting it into use can increase the vacuum of the equipment and increase the pumping capacity of the pump, thus effectively improving the efficiency of the equipment and reducing the waste of resources.
