Introduction:

Electric fire pump + Diesel fire pump +Jockey pump



Introduction:

Generally an automatic fire water supply system consists of a Jockey pump, an electric fire pump (main pump) and an automatic diesel fire pump set (standby pump).

The split type diesel engine control cabinet (programmble) can realize these functions: system's self-start, operation self-cut-over (from Electric pump to Diesel engine pump or from one diesel engine pump to another diesel engine pump), self-protection (in case of over speed of the diesel engine, low oil pressure, high water temperature, 3 times failure of start, low oil level and low voltage of the battery etc.). Besides, the pump can be connected with fire center or fire alarm, which can easily realize remote control.

The diesel fire pump group can be connected to electric constant pump to realize self fire water supply system.

With the difference in water inflow, the fire pump can be grouped into two groups: Self-filling pump, and suction pump. Normally we provide self-filling pump. If client needs suction system, please point out, our company will provide vacuum self suction device, with little changes of the pump size.

 

Performance and Characteristics:

Complete three starting functions:

1.Manual starting: available for manual and automatic interlocking and for manual starting through the change-over switch;

2.Automatic starting: allowable for three times of starting; sending out “starting failure alarm’ and exiting from the starting state in case of starting failure after three times; if starting is successful once, the time of starting to the rated load is 5-10-15S(subject to the pump set’s capacity);

3.Emergency direct manual starting: available for emergency direct manual starting in case of failure of the automatic control device.

4. Automatic operation: when the water pump set receives an effective fire control signal, the diesel fire pump set will start and operate automatically if the motor fire pump’s power supply system is power-off or open-phase or the electric pump fails to start normally. Once the power supply system returns to normal or the electric pump can work normally, it can be switched to the electric pump automatically.

5. Automatic stop: when the fire control signal disappears, the diesel fire pump will stop in a delayed and automatic way.

6. Automatic charge and voltage-stabilizing function of accumulator: the accumulator can use the mains supply for the automatic charge of the diesel’s rechargeable motor to ensure the pump set’s smooth starting.

 

Complete indicating system:

Ready to start, manual starting, automatic starting, set operation, set stop, accumulator charging, over speed, under pressure of diesel lubricating oil, under pressure of oil of pressure booster, under temperature of diesel lubricating oil, over temperature of diesel cooling water, under voltage of accumulator, too low level of fuel oil(or in short), preheating for under temperature of diesel cooling water, and timed in-process check.

 

Complete alarm or protection system:

Alarm or protection for starting failure for three times, over speed, under pressure of lubricating oil, under pressure of oil of pressure booster, over temperature of cooling water, and under temperature of lubricating oil; alarm for failure of automatic charging device and under voltage/over voltage of accumulator; and alarm or protection for low level of machine oil.

 

Complete display system:

1.Display of lubricating oil pressure and rotation speed of diesel, and charging current and voltage accumulator.

2. Adjustable flow and pressure: the diesel water pump is mounted with a mechanical or electronic speed regulator which can regulate and change the diesels rotation speed when the water pump's (low and lift head are not in conformity with the actual conditions.

3. Double accumulator loops: when one accumulator set fails, another set can be put into use automatically.

4. Maintenance-free accumulator: unnecessary for frequent filling of the make-up fluid.

5. Automatic timed in-process check test: generally the fire system is in a standby state, and this pump set is available for testing its standby state automatically and also for alarming promptly.
