Q:Two pumps automatically switch start control circuit,
The puddle is full, the float switch is closed, and the relay J1 works to drive the first motor. The J1's work makes the intermediate relay 'J' work and locks itself, preparing for the work of the second machines. The water level is lowered to the required minimum position, the ball is broken, the motor is stopped and the motor is stopped. When the water level rose to the highest position again, the floating ball closed again, the relay J2 and self-locking relay J2 to drive second motors, instant intermediate relay are opened, when the water level again be reduced to the lowest position, float off, the motor stops working, stop by working in front of the intermediate relay. The whole circuit back to the original state. So that the two motors work alternately.It should be noted that the circuit diagram for simple to understand, only painted the control circuit, there is no main circuit, there is no missing phase, leakage, over-current and other protection, the actual installation needs to be installed. There is the role of time relay is to ensure that the relay J2 normal work, the intermediate relay is disconnected, so that the motor 2 does not occur wrong action, time relay can be set to a few seconds, or even less than a second. Intermediate relay can also be controlled by time relay, and its time is also set very small, so as to avoid J2 short time possible power supply.
Q:Pump head is too high what's the impact?
Water pressure is too large, energy consumption is too high, you can choose near the flow of Yang Cheng
Q:What is the difference between a low pressure pump and a high pressure pump?
The magnitude of the pressure at the outlet side of the pump
Q:When using a frequency converter to adjust the pump, what is the relationship between the change of the speed and the efficiency of the pump?
The wind pumps such load is usually called square torque load, which is in a certain range of speed and torque is roughly proportional to the square of the speed of N, TL=kn^2, power and speed is proportional to the cube, the energy-saving effect is obvious.
Q:2 pumps parallel, lift the same, pump head is not stacked?
2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.
Q:What does water flow mean?
Forehead... Flow do not understand it....
Q:A direct type pump model with the coupling type, what is the difference?
The direct type shall be the same shaft of the pump and the motor, and the connecting shaft is a pump and the motor shall be 2 shafts, and shall be connected by a shaft coupling.
Q:Electrical design into!!! Is the water pump lamp waterproof?
The ordinary pump houses are ordinary energy-saving lamps, but there is a glass shield outside of it which is waterproof...And they're all emergency lights!Like some large pump houses, they have riot lights...
Q:Fire pump room is required to set up water pump control room?
What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control
Q:What's the submersible pump?
Zhengzhou sea diving pump. Deep well submersible pump is a fountain, drinking water transportation, irrigation, hot springs, high-rise transport facilities, etc., deep well submersible pump excellent performance, so widely used in various fields.
