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:Why does the pump decay when connected in parallel?
Pump parallel mainly solves the problem of insufficient flow. After parallel, the flow is two and the sum of the pumps. When the flow rate increases, the pressure loss of the pipeline will increase, so the water pump flow in parallel will not be the sum of the two pump flow, but less than the sum of the flow rate. The solution is to increase the diameter of the water supply pipe, reduce the angle bend and shorten the distance.........
Q:What does the lift of a pump mean?
Simply from the local to the pumping pumping height calculation of rice
Q:Fire hydrant and fire pump adapter difference
The most simple argument is outside fire hydrant water pump adapter, irrigation from.More outdoor fire hydrant, both sides of the road can be seen at any time, that is, red like a villain, there is a hat on the head. Pump adapter is not that hat.
Q:Do you need a stop valve for the pump at home?
Must be connected, in the low-end water pipe, the valve is also called the bottom valve is to prevent the intrusion of water, at the same time, but also to ensure the pump again next time when starting the pump and piping in enough water to prevent idling.
Q:Relationship between pump voltage and lift?
In the case of power, W=F*S. That is, the work done per unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.
Q:What's the function of the engine pump?
Random occurrence of Internet cafes; on; come; time; two ah is a few karma; feeling ah; ah, just
Q:What is a 1 inch water pump?
The outlet is 1 inches (25MM) of the water pump
Q:Domestic pump does not turn, but the motor is energized what is the problem?
The home pump does not turn, but the motor is energized:A: there are heard buzzing, but can not move and no death card. It is likely that the boot capacitor is broken and that the capacitor can be measured with a universal meter.Two: if the motor is sure to have electricity, check whether there is low voltage or broken phase (three-phase motor). These conditions also cause the motor not to rotate, or the speed is low (easy to block), so it should be measured with a universal meter.Three: you can smell there is no burning flavor, may be motor winding interphase short-circuit. Bearings should be hard to break, and it's probably not good to find repairs.If the capacitor is replaced, it is better to choose the same capacitor as the original configuration parameter. If the capacitor is damaged and does not know or can not see the mark parameter, it can be calculated and matched according to the following formula:In C=8JS (F), the capacitance of the C- is S- (F). The current density of the starting winding of J- motor is generally selected from 5 to 7A/ (mm) 2, and the cross section area (mm2) of the starting winding winding. Generally, you can choose 1000W/40 F.
Q:30kW what is the flow rate of the pump?
Estimated traffic: Q = nP/ (9.8H), =70%*30/ (9.8H), =2.14/H (m^3/s)It is estimated that the efficiency of the water pump unit n=70%, power P to kW as a unit, the head H to m as a unit, you go to check the head H is how many meters, into the formula can be considered the flow rate is how many cubic meters per second.
