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.

The pressure tank, also known as the pressure tank, is one of the important components in the secondary water supply equipment. Its core function is to stabilize the water pressure, so it is called the pressure tank.
The reason why the surge tank can stabilize the water pressure is mainly achieved by compressing the gas in the capsule, because water is an incompressible fluid, and water with the same pressure can compress the gas to store water and have a certain pressure.

The multistage pump is a centrifugal pump in and out of the water section and the middle section, through the rod combination together, its output water pressure can be very large, but also depends on the rotation of the impeller to obtain the centrifugal force, so that the material. When the gas density reaches the working range of the mechanical vacuum pump, it is extracted, and the high vacuum is gradually obtained.

The housing of the diesel engine fire pump constitutes the working chamber of the pump. The impeller, shaft and rolling bearing are the rotors of the pump. Suspension bearing parts The supporting parts support the rotor parts of the pump, and the rolling bearings are subjected to the radial and axial forces of the pump. In order to balance the axial force of the diesel engine fire pump, most pumps have sealing rings at the front and rear of the impeller, and a balance hole on the back cover of the impeller. Because some pumps have little axial force, there is no seal on the back of the impeller. ring and balance hole. The axial sealing ring of the diesel engine fire pump is composed of packing gland, packing ring and packing to prevent air intake or large water leakage.
