Deep well fire pump unit

Deep well fire pump unit

Presentación del producto

1.The deep-well fire pump unit is developed in accordance with the Fire Protection Standard G86245-2005 of the People's Republic of China, "Fire Pump Performance Requirements and Test Methods." This product has undergone type testing by the China Fire Equipment Quality Supervision and Testing Center, and all performance indicators meet the standard requirements, earning it a Fire Product Approval Certificate.
2.The deep-well fire pump unit consists of multiple centrifugal impellers and a guide casing, a water pumping pipe, a drive shaft, a pump base, and a motor. The pump base and motor are located above the water tank. The motor's power is transmitted to the impeller shaft via a drive shaft concentric with the water pumping pipe, generating flow and pressure.
3.Vertical Structure: This series of vertical multi-stage water intake equipment features a compact footprint. Its working components can reach depths of up to 100 meters to extract fluids, and it offers a variety of drive modes.
4.Various Operating Conditions: Depending on the pumping medium and other operating conditions, we offer motors with different materials, structures, and requirements to meet various customer needs.
5.Compact Structure: This unit features a wide flow range, high head, compact design, and stable operation.

Core Advantages

1.Fully Electric Protection
Prevents impacts during production and protects the stator coils
2.High-performance design, no burnout
Built-in overload protection and phase loss protection prevent burnout
3.Long-lasting durability
Long bearing life, low noise, and energy savings
4.Excellent heat dissipation
Full contact between the core and the casing ensures excellent heat dissipation and low operating temperature rise.

Aplicaciones

Deep well fire pumps are mainly used in fire hydrant fire extinguishing and automatic sprinkler fire extinguishing systems in fixed fire protection systems such as industrial and mining enterprises, engineering construction, high-rise buildings, etc. They can be used to transport clean water without solid particles and media with chemical properties similar to water. They can also be used in shared water supply systems for life and production, as well as construction and municipal water supply and drainage.

Especificaciones

1.Liquid flow rate range: 5-100 L/s
2.Lift range: 32-200 m
3.Power range: 3-200 kW
4.Rated speed: 2900 r/min

Operating Conditions

1.The rated frequency is 50 Hz, and the rated voltage at the motor end must be guaranteed to be 380 ± 5% volts for a three-phase AC power supply.
2.The transformer load power should not exceed 75% of its capacity.
3.When the transformer is far from the wellhead, the voltage drop of the transmission line should be considered. For motors with a power of more than 45 kW, the distance from the transformer to the wellhead should not exceed 2 meters. If the distance is greater than 20 meters, the transmission line should be two grades larger than the distribution cable, and the line voltage drop should be considered.
4.Generally non-corrosive clean water with a solids content (by weight) of no more than 0.01% is recommended.
5.The water temperature should not exceed 40°C, the pH should be between 6.5 and 8.5, and the hydrogen sulfide content should not exceed 1.5 mg/L.
