Long continuous operation time.

For end suction pumps and since water is entering one side of the impeller, and due to the design of “Impeller overhung”, these pumps cannot be used for large water flow applications and usually not exceeding 1500 gpm of flow.

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.

Vertical turbine pumps are often preferred for applications where a high flow rate and high head (pressure) are required. They are also well-suited for use in deep wells or reservoirs where a submersible pump may not be practical. Additionally, vertical turbine pumps are typically more efficient than other types of pumps in certain operating conditions.

Vertical inline close coupled fire pumps are specifically designed for vertical mounting. The suction and discharge nozzles are located on the same centerline 180° apart. Vertical pumps significantly reduce required mounting space. They are easy to maintain.

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.

The waste cone is providing quick visual confirmation of proper water flow in the fire pump system.

Explosion-proof motor is a type of motor with explosion-proof performance. The measures taken are: the electrical equipment cover is installed in a casing, which has a structure that can withstand the explosion pressure of the internal explosive mixture and can prevent the internal explosion from spreading to the explosive mixture around the casing (flameproof type); make the motor Live parts are not likely to generate sparks, arcs or dangerous temperatures sufficient to cause an explosion hazard, or isolate live parts that could produce these phenomena from the explosive mixture so that they cannot come into contact with each other or to the extent that they are explosive (increase safety type, ventilation type, etc.). In all kinds of environments with explosive danger, it is very important to choose the explosion-proof motor matched with all kinds of equipment correctly.
