Q:What's the difference between a double suction pump and a single suction pump?
The 3 floor of a friend, the next time you quote us the trouble to answer, please indicate the source, at least to keep integrity! Now on the market a variety of micro pump, micro pump, micro pump, high pressure micro water pump, liquid sampling pump, small pump, self suction pump, DC pump, diaphragm pump, whether has the function of self suction, mainly refer to the following two points: 1. means: self suction pump suction pipe is in the air, using form a negative pressure pump at work (vacuum), under the influence of the atmospheric pressure will be lower than the water pumping port, then discharged from the pump discharge end. Before this process, there is no need to add "diversion water". The pump with this capability is called a self suction pump". 2., some centrifugal or rotary vane pump, before absorbing water, you must add "water diversion" in the pump cavity to form a closed environment, and then pump operation to form negative pressure, to achieve the purpose of water absorption. For example, a manual pump used in rural areas. No self-priming capacity of the pump, each time before adding water to add "water" is very troublesome. 3., suction level, with the pump power, flow, structure and so on, but the general micro pump self-priming process is not easy to do higher
Q:The role of impeller in water pump
The impeller is driven by electric motor rotation, the middle impeller creates a vacuum to vacuum at the inflow of water will be (on the surface water is continuously sucked into the impeller), then the water through the high-speed rotation of the impeller of the water discharge, play a promoting role in water.
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:Pump adapter belongs to the system of fire pool equipment?
Does not belong to the fire pool system! Pump adapter is mainly used for fire engines through the adapter system pressure, outdoor fire hydrant fire with one hand, one hand is to provide water for the fire truck. According to the 10~15L/S calculation of each pump adapter
Q:Stop the engine immediately and stop the circulating pump and the condensate pump. What's the harm to the turbine?
Stop the condensate pump is not required to condensate users, such as reducing water, mechanical seal water, shaft seal cooling water, deaerator, whether you need water. Stop circulating pump requires three: 1, exhaust steam temperature below 50. 2, there is no circulating water users. 3. No drain to condenser. If stop immediately stop circulating water and condensate pump, the consequences can be imagined.
Q:Domestic pump automatic shut off the water, but also turn around, stop what happened?
Absolutely at the pressure switch, just under pressure. The shell open pressure switch, will see there is a spring, the screw is to adjust the pressure of the ~ ~ ~ try, and I've done a lot.
Q:What does water flow mean?
Forehead... Flow do not understand it....
Q:What are the conditions for the series and parallel connection of the pumps?
1, pump series, the two pumps must start and stop at the same time in order to normal operation.2 when the pump is connected in parallel, the two pumps must be equipped with check valve at the same time to operate normally.3, of course, in the election of the pump, should meet the requirements of upstairs said.
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:How many lift pumps should be used for 100 meters tall buildings?
At least 130m guarantee that the top floor customer has 3KG water pressure
