Product Description:

Referring to powered by diesel engines, pumps by elastic coupling driven by diesel engine, with advanced and reasonable structure, high efficiency, good cavitation performance, little vibration, low noise, smooth operation, reliable and convenient installation

The characteristics of
1, the automatic starting
Diesel water pump sets received/power/fire/pipe network pressure or other start signal after, in 5 to 15 seconds will automatically start and running at capacity;
2, automatic charging
Battery charged can use mains or diesel motor automatic charging, ensure its smooth starting;
3, automatic alarm,
On diesel engine low oil pressure, high temperature, such as fault automatic alarm protection, alarm and shutdown when speeding;
4, automatic preheating: make diesel engine standby state, ensure emergency work;
5. Direct type: below 360 kw diesel pump unit using the first domestic diesel engine and pump through flexible coupling connection technology, directly reduce the point of failure, and greatly reduces the starting time of generating units, increase the reliability of the unit and emergency performance;
6, other alarm output
Users can also request other alarm output Settings.

Q:Does the lift of pump relate to the water level of import and export?
Pump head refers to the inlet and outlet pressure head, that is to say, the entrance resistance greatly affects the pump lift, of course, this inlet resistance has a degree, too large water pump does not bring water or cause water pump cavitation. If the water level at the pump inlet is the same height, the inlet flow resistance of the pump may not be considered.
Q:90kw pump star delta start, in the end to use the circuit breaker, AC contactor (Star contactor, angle contactor), what kind of thermal relay?
Imports, such as Schneider, press: plastic case press 250A, contactor select 115 of 2, 95 of 1 can.Domestic recommendations: Press: plastic case press 250A, contactor 160, 2, 115 of the 1 can.
Q:How do I know the pump pressure?
That is, the rated pressure minus the pipe loss, and then less inlet pressure (generally suction pump inlet pressure is negligible), that is the working pressure.The head of a centrifugal pump is also called the pressure head of a pump. It is the energy gained by the pump of the unit weight and the fluid. Pump head size depends on the structure of the pump (such as the diameter of the impeller, the bending of the leaves and so on, speed. At present, the pressure head of the pump can not be calculated accurately in theory, usually measured by experimental method.
Q:Does the water pump and the circulating pump belong to the centrifugal pump?
They're all centrifugal pumps!
Q:A direct type pump model with the coupling type, what is the difference?
The water pump type is directly connected with the motor, and the motor shaft and the pump are coaxial;Pump motor and pump shaft is separate, with the coupling power transmission.
Q:How can I pump the motor insulation?
The cable head in the distribution box should be relieved. What's more, the motor insulation is not the pump insulation. Usually, just shake it in the middle of the water and the ground.
Q:Electrical design into!!! Is the water pump lamp waterproof?
No specific requirements are available
Q:What is LG water pump?
LG pump LG refers to the name of the water pump brand, not on behalf of practical significance.LG pump is a high-rise building feed pump.1, LG, LG-B type of high-rise building water supply pump is a vertical multistage type structure, bolt the inlet section, the middle section of the water pump are fixed together, each containing a impeller and the guide vanes, the axial force of the hydraulic balance, the residual axial force by one or a pair of ball bearing;2, the shaft seal adopts special design mechanical seal, so when dismantling mechanical seal, do not need to remove the motor, the middle casing coupling can be removed from the seal, it has the advantages of replacement and convenient maintenance;3, pump transmission is through the shell coupling, vertical motor drive, from the motor side to see, the pump clockwise rotation;4, the suction inlet of the pump is below, the water outlet is above, and its relative position can be chosen according to the user's requirements, 0 degrees, 90 degrees, 180 degrees, 270 degrees for assembly, factory. General pump 180 degrees factory.5, assembly without adjustment, easy disassembly;6, the motor can be equipped with standard Y series of ordinary models.
Q:Why can't vertical water pump use spring shock absorber?
Building water supply and drainage and heating engineering construction quality acceptance specification (GB50242-2002) on the 4.4 water supply equipment installation 4.4.6 regulations. Because the spring damper is not conducive to the stability of the vertical pump running, therefore, the vertical water pump damping device should not use spring shock absorber.
Q:How can the pump be stationary?
1, the pump bearing lubrication interruption, bearing burn.2, locking the rotor is jam.3, foreign body corrosion serious impeller lock.
