Product Description
Products Name: UL listed fire pump with Vertical Single-Stage
Overview:
XBD vertical single-stage fire pump set is based on our IS type pump, combined with the characteristics of foreign pipeline pump, optimization design and manufacture of a new generation of products by itself. Use of fire hydrants in the water, feeding sprinkler system water supply in other occasions cleaning liquid.
Conditions of use:
1. XBD vertical single-stage fire pump set is used for transporting ambient water.
2. The water does not contain corrosive substances and solid particles.
3 Minimum working pressure 0.3Mpa, the maximum working pressure of 1.6 Mpa.
Characteristics of XBD vertical single-stage fire pump products
4, the pump is a vertical structure, import and export of the same caliber, and are in the same center line, as the valve can be installed in the pipeline, compact appearance, small occupation area, low construction inputs, such as protective cover can be placed outdoors
5, the impeller mounted directly on the motor lengthened shaft, short axial dimensions, compact structure, pump and motor bearings reasonable configuration, can effectively balance the pump running the radial and axial load, so as to ensure the operating balance vibration noise of the pump is very low.
6, seal mechanical seal mechanical seal or a combination, the use of imported titanium alloy seal ring, medium and high temperature mechanical seal with cemented carbide materials, wear-resistant, can effectively increase the service life of mechanical seal.
4, convenient installation and maintenance, no need to open the pipeline system, remove the pump as long as the union nut can block out all the rotor parts.
5, can be used according to the requirements that need to flow and head of the pump series, parallel operation.
6, according to the requirements of piping layout using the vertical and horizontal pump installation.
Performance requirements of fire pump is:
1. Maximum flow fire pump shall be 150% of the value of the design, the head is not less than the selected operating point of 65% lift, lift off the pump when not greater than the selected operating point of 140% lift, pump flow 1 2LS, head 1.1 - 1.2 times the fire pump lift.
2. At the same time in the fire pump outlet pipe should be located on measurement flowmeter, flow meter should be able to test 175% of the pump flow rate selected, fire pump pressure gauge set should be greater than 89mm in diameter at the outlet pipe.

failure cause |
elimination methods |
| |
1.No power supply or one or two phase power supply is needed |
Check all phases of power supply and restore power supply
|
| |
2.Poor contact of ac contactor and burning of coil |
Repair or replace contactors
|
| can not start |
3.
The power switch is not closed, malfunction or damaged
|
Close the switch and replace it if the power indicator does not turn on |
| |
4.
Thermal relay trip or damage
|
Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started |
| |
Water level is too low |
Put water in the sink
|
| |
The motor burned |
Repair or replace the motor
|
| |
1.Line is loose |
Check wiring and tighten connectors
|
| |
2.Frequency converter malfunction |
Check the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting. |
| The manual is normal |
3The frequency converter is damaged |
Repair or replace |
| Automatic transmission failure |
4.Pressure switch damage |
Repair or replace |
| |
5The pressure transmitter is damaged |
Repair or replace |
| |
6.Switch failure |
Repair or replace |
| Pump non - suction pressure gauge pointer to beat violently |
Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument |
Check pipeline and bottom valve, refill water diversion. Tighten air leakage |
The pump consumes too much power
|
Too much flow, impeller wear
|
Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow |
