Q:What is the function of the backflow pipe of the fire pump?
Generally, it is used to test the fire pump. The procedure is to start the fire pump - turn on the return pipe - return the water to the pool. The purpose of the installation is to prevent damage to the pipe caused by the excessive pressure caused by the pump.
Q:Water pump maintenance what should be maintained?
1 by sound to determine whether the bearing is good. If the sound is abnormal, replace the bearing.2, check whether the impeller is worn, if worn, will affect the flow, lift, efficiency, need to be replaced.3, check whether the mechanical seal can continue to use, can not be used, need to be replaced4, check the oil tank is missing oil, such as lack of oil to the appropriate location.
Q:How to connect the household pump capacitor?
220V has two lines (lines 1, lines 2)There are two lines of capacitance (line 3, line 4)There are three lines on the motor (line 5, line 6, line 7)3 11 52 64 7That's plain enough. To change the turn, change any two of the 5, 6, 7, three lines
Q:How do I calculate the power of the pump?
A 15kw pump, know how to calculate the head pumping water for an hour (if the head is 10 meters)Lift: MFlow rate: kg / sec (general water pump is cubic / hour, if 10 cubic hour / hour: 2.7 kg / sec)Efficiency: average 60%15000/102*0.6=88 kilograms per second88/10=8.8 kg / sec8.8*3600=31680 kg / h=31.6 cubic / hour
Q:Is the pump lift horizontal or vertical?
The vertical height from the center line of the pump impeller to the surface of the water source
Q:How can the pump be stationary?
1, the pump can move under the premise of turning disc. Pump should be empty load start, that is, in the closing of the export valve in the state of start, there will be no rotation of the situation.2, look at the voltage of the circuit is normal, whether the lack of phase.
Q:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?
In fact, the key to this problem is to figure out what is frequency conversion, why frequency conversion, know this problem, we can easily understand the difference between frequency converter pump and ordinary water pump.We often say that the frequency is a frequency conversion process of the motor, the frequency of the motor to change the motor speed, so as to achieve the water pump flow head technology parameters are adjusted to control the role of.Variable frequency water pump refers to the motor, variable frequency pump should be driven by variable frequency motor pumpFrequency conversion, that is, adjustable frequency, frequency conversion motor is able to adjust the speed, adjust the flow, to achieve the purpose of energy saving, but also start small current, maintenance advantages of small workload.Ordinary water pump is to use ordinary motors to drive water pump rotation, that is called the power frequency motor. Our daily use frequency 50Hz, can not speed. Water pump adjustment flow through the valve throttling to achieve the same, so it is not energy-saving. The fear of harm in Wei Di apps
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:Ask the principle of fire truck and pump adapter
The water injected into the water pump is the water on the fire engine, and the fire engine is supplied by the city fire hydrant.
Q:Horizontal pumps, vertical pumps, which kind of expensive?
Not expensive, depending on the specific model, in fact, the vertical pump is not much
