Product Overview
The fire pump set is a new generation of products designed and manufactured on the basis of our water pumps, combined with the characteristics of foreign water pumps and optimised by ourselves. It is used for water supply in fire hydrant, water supply in sprinkler system and cleaning liquid in other occasions.
Use conditions
1. Vertical single-stage fire pumps are used for conveying normal temperature water. 2.
2. The water does not contain corrosive substances and solid particles.
3. the minimum working pressure is 0.3Mpa, the maximum working pressure is 1.6Mpa.
Features of vertical single-stage fire pump
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.
| fault phenomenon | 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 |
| Parameter Description: | |
| Liquid flow range: 1-120L/s | Lift range: 30-160m |
| Rated speed: 2900r/min, 2850r/min | Supporting power range: 1.5-200KW |
| Working conditions: | |
| Meson temperature: -15ºC~80ºC The ambient temperature is not higher than 40ºC and the relative humidity is lower than 95%. It can transport clean water or non-corrosive media with physical and chemical properties similar to clean water, and the solid insoluble matter does not exceed 0.1%. |
|
| Core advantages: | |
| * Electric full protection to prevent bumps during production and protect the stator coil * Long-lasting and durable bearings with long service life, low noise and energy saving * High configuration without burning the machine Built-in overload protection, phase loss protection, no machine burnout * Good heat dissipation effect. The iron core is in full contact with the casing,which has good heat dissipation effect and low operating temperature rise. |
|
| Applications: | |
| it is mainly used for pressurized water delivery in fire protection system pipelines. It can also be used for industrial and urban water supply and drainage, pressurized water delivery in high-rise buildings, long-distance water delivery, heating, bathrooms, boiler hot and cold water circulation pressurization, air conditioning and refrigeration systems and equipment matching, etc. | |
