1. Altitude: ≤2,500 meters 
2. Environmental temperature: - 25 ~ 55 ºC 
3. Relative humidity: 9 ~ 95% 
4. Seismic intensity: 7 degrees 

Main Features of Diesel Engine Fire Centrifugal Pump XBC Series
1. Automatic starting: when receives fire/pipe pressure/power failure/or other start signal, it can automatic start and devote to full load operation in 15 seconds. 
2. Automatically charges: battery charging automatically from electric power or charging motor in diesel engine so as to ensure its smooth start-up, 
3. Automatic alarm: when diesel engine under low oil pressure, high temperature water and other problems, it would automatic alarm, and alarm and stop when over-speed. 
4. Automatic preheating: make the diesel engine in the spare state, ensure emergency work. 
5. Direct coupled type: below 360kw diesel pump unit adopt diesel engine and pump connected through elastic coupling directly technology, reduces the malfunction points, and shortens start-up time greatly, increase the reliability and emergency performance. 
6. Users can also required another alarm output (non standard delivery); 
7. With remote measure, remote communication, remote control (non standard delivery);

Q:What does "ETA" mean in the selection of pumps?
NPSH refers to the cavitation, the pump is the technical parameters
Q:Submersible pump and self-priming pump which is easy to use?
Dive into the water and leave alone
Q:What motor does the pump use?
Hello, the pump is generally used permanent magnet synchronous motor, and if the motor is not too understand, you can consult the motor suppliers, according to the model to choose their own use.
Q:Water pump "rated lift: 6m" what do you mean?
Lift refers to the weight of fluid per unit weight after the pump, the pump is an important working parameter, also known as pressure head. Simply stated: rated lift 6M refers to the rated operating conditions of the pump, the increase of energy 6M water column height. Here's an example to help you understand:Example 2-1 the head of a centrifugal pump is now measured. The refrigerant is 20 DEG C water, the measured flow rate is 60m^3/h, vacuum pump inlet meter 0.02Mpa, outlet pressure gauge readings for the 0.47Mpa (g), the two known table between the vertical distance is 0.45M if the suction pipe of same diameter and pipe pressure pump, calculate the pump head.Solution:Check the water density at 20 centigrade 1.0*10e3kg/m3,H=0.45m (1Mpa approximately equal to 100 m water column)P exports =0.47Mpa (0.47*100 m water column, =47 m water column)P imports =-0.02Mpa (0.02*100 m water column, =2 m water column)P is the density of the liquidH=h+ (P -p / P g=0.45+ export import) (0.47*10e6- (-0.02*10e6)) / (10e3*9.887) =50.5m (water)
Q:How to remotely control submersible pumps?
This is relatively easy to implement, to a remote control within the specified scope control, and use mobile phone SMS or ringing control, you make a phone call or Clockwork SMS can control the submersible pump switch, the switch is not used since a ran. This remote control switch products, in the Alibaba, my family has used, it is convenient, not expensive, more than 100.
Q:Water pump motor overload
170A has shown that the motor is overloaded; the head 70M; the displacement of 180 cubic meters; the approximate power is 42Kw (efficiency is higher). At this point, the current of the corresponding motor should be approximately 86A;The power of water pump is related to the quantity of water transported. The water pump is a passive energy conversion device, and it has no regulating ability. It depends entirely on the intersection of its pipeline characteristics and its own characteristics,No, your situation is the pump and pipeline characteristic, the pump head is higher than the resistance of pipeline, so that the water flow movement (increase too large). Pump power becomes largerShut down the water pump, the valve will certainly reduce the amount of water, as for whether to reach 180, you can see the pressure gauge to show the pump lift to determine the pressure of less than 70 meters, the flow of more than 180
Q:Fire hydrant and fire pump adapter difference
Fire hydrant is out of water, the water pump is water supply to the pipe network
Q:The efficiency of water pump frequency conversion is very low, why?
Variable frequency pump running normally, its flow and lift is lower than the power frequency operation, that is for sure. The so-called power frequency operation is full speed operation, of course, the head and flow is the highest.Frequency conversion is mainly to save power and reduce the running loss of equipment. The so-called efficiency, but also by the correct selection, the actual pump head and flow as close as possible, the actual working conditions for the best.
Q:Think of several households sharing a pump
The electromagnetic valve is estimated to be expensive to death ~!You set up a high water tank in the middle of the user. The pump is pumped to the water tankIn each according to the water meter, then according to water allocation total cost ~ ~ ~!
Q:Pump power ratio design is small, the problem is big?
No problem, despite the good use of different water pump factory manufacturing process is different, the product of the rich value of different factors, power difference is inevitable, as long as the flow and head to meet your use requirements.The calculation formula tells you: your flow is 72 tons / hour, lift 90 meters, motor power P=2.73HQ/0.75*1.2=28.5KW
