The fire-fighting water provided by most fire-fighting water sources needs to be pressurized by fire-fighting water pumps to meet the requirements for water pressure and water volume during fire-fighting, which is an important part of fire-fighting. In daily use, we often encounter fire pumps vibrating or making abnormal noises. What is the problem?
1. The installation is not firm and the fasteners are loos

2. Wear between impeller and seal ring

3. Improper installation of pump body and pump shaft

4. Cavitation causes abnormal sound inside the pump

When selecting a firefighting pump, factors such as the intended application (e.g., residential, industrial, wildland), required flow rate and pressure, available power source (e.g., gasoline, diesel, electric), portability, and budget should all be taken into account. Consulting with experts or fire safety professionals can help ensure you choose the right pump for your needs.

Minor repairs can often be made to fire pumps, but major issues may require replacement or extensive refurbishment. It’s important to consult with experts in fire pump maintenance for guidance.

1. The fire pump should be capable of supplying the rated flow and pressure for a duration of two hours, at a rate of 150% of the rated capacity, and should not be affected by prolonged operation.

2. The fire pump should be able to start up automatically by a power source when activated.

3. All switches, gauges, alarms, controllers and monitoring systems should be certified to UL and FM standards.

4. The fire pump should be sized to meet the NFPA 20 standard for fire pump design.

5. The fire pump should be able to handle the maximum system flow and pressure required for the building.

6. The fire pump driver should match the requirements of the pump and meet NFPA 20 requirements for fire pump drivers.

7. The fire pump should be installed according to NFPA 20 standards for fire pump installation.

Double power fire pump product advantage is that when a fire occurs, a more reliable way to ensure water safety, in the normal power supply when the electric pump group into work, when the power supply failure, the electric fire pump can not be normally put into use, the diesel fire pump group can automatically put into operation to ensure the normal fire fighting.

1. Manual Operation: This method involves manually operating the fire pump by an operator who is trained to handle it.

2. Automatic Operation: This method uses an automatic sensing and control system to start and stop the fire pump when needed.

3. Pressure Control: This method uses a pressure switch to monitor the pressure in the system and activate the fire pump when necessary.

4. Flow Control: This method uses a flow switch to monitor the flow in the system and activate the fire pump when necessary.

5. Variable Frequency Drives (VFDs): This method uses a VFD to provide precise control over the speed and torque of the fire pump. This helps to ensure that the fire pump is operating optimally.

6. Remote Monitoring: This method uses a remote monitoring system to provide real-time data on the condition of the fire pump and to allow for remote operation if necessary.

According to customer requirements, the fire pump set is composed of electric pump, diesel pump and jockey pump. Both manual and automatic operation are available. The three pumps are automatically switched and can work even when power is off. Our company is a professional The company has a professional sales and technical team, which can be customized according to its own needs.

After receiving the fire/pipe network pressure/power failure/other start signals, the diesel engine fire pump can automatically start and enter full load operation within 5 seconds. The battery can be automatically charged by the main power supply or the diesel charging motor to ensure the smooth start of the equipment; automatic alarm protection for low oil pressure, high water temperature and other faults of the diesel engine, overspeed alarm and shutdown; the diesel engine fire pump is in a hot engine standby state to ensure emergency work. The diesel engine fire pump adopts the direct connection technology between the diesel engine and the water pump. Through the elastic coupling, the failure points are reduced, the start-up time of the unit is greatly shortened, and the reliability and emergency performance of the unit are improved.

The fire pump is mainly used to deliver water in the fire system. As an indispensable tool for the fire system, the fire pump has the characteristics of simple structure and stable performance. Due to these advantages of high performance and low energy consumption, the safety and efficiency of the fire pump are far ahead of the pipeline tools of the same purpose.

1. Perform regular maintenance on the fire pump as recommended by the pump manufacturer.

2. Visually inspect the fire pump periodically and repair any damages or leaks detected.

3. Make sure that the fire pump is adequately cooled and lubricated as specified by the manufacturer.

4. Test the fire pump regularly with a suitable hydrostatic pressure test to ensure that it is functioning as designed.

5. Replace the seals of the pump regularly as necessary.

6. Ensure all electrical connections are proper and secure to avoid short circuits or other electrical problems.

7. Keep the fire pump area clean and free from dirt, dust, and debris.

One way of choosing a diesel generator as a backup power source for fire protection is because in fire protection, two power supplies are required, which can be two power plants and two transformers, or one line of city power and one line of diesel generator set power supply. Meet the requirements of fire backup power.

The electric pump of this fire pump group adopts XA pump, which has good suction performance. The suction section of the pump is of an expanded structure, which reduces the flow rate of the pump inlet, so that the pump has good suction performance, a small necessary NPSH, and improves the prolongs the service life of the impeller and pump casing.

The minimum fire rated pressure of ED small fire fighting package set water supply equipment is 3 bar and the minimum fire rated capacity is 25 GPM. ED small fire fighting package set water supply equipment includes at least two power or power source driven pumping units, pressure tanks, pipes, valves and accessories, measurement and control instruments, control cabinets, outdoor rain cover, etc.

Diesel Pumps: Diesel pumps can use vertical in-line pumps, horizontal end-suction pumps, vertical multi-
stage pumps, horizontal multi-stage pumps, split casing pumps and so on according to the different flow and head of customers.
Electronic Components: The main electric components is CHNT, if Schneider or other brand electrical are need, should mention it before place the order.
Safety Valve plays a safety protection role in the system. When the system pressure exceeds the prescribed value, the safety valve opens, and a part of the gas/fluid in the system is discharged into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.
Pressure Tank: Water is a non-compressible medium. Generally speaking, the pressure drop of fire-fighting pipe network is normal. However, the pressure drop is very slow, the total loss of water in the pipe network isnot large, and the frequent change of pressure in the pipe network leads to frequent start-up and shutdown of pumps. Especially when the power of equipment is high, it will cause great impact on pressure sensors, relaysand motors, thus affecting the performance and life whole equipment. Therefore, it is necessary to choose the right volume of the pressure tank.
