Q:QDX is a submersible pump. What does "X" mean?
Q submersible pumpsD single-phase motorX downdraft
Q:Level 200 meters distance, elevation 30 meters, how much lift water pump?
According to the horizontal distance of 10 meters is 1 meters lift, 200 meters is 20 meters and 5 meters height difference of 30 Mega elbow, pump head floating down 10%, should be about 60 meters.
Q:Is there a water pump with its own flow regulating function?
Pump with adjustable flow depends on your useThe ordinary displacement pump, which has a small flow rate, can set the flow rate per second into the system and is widely used in the laboratory.Large flow regulating flow pump is mainly variable frequency pump, through the electrical signal feedback regulation, change the pump water storage flow.The main thing is to see your flow, and then determine what you want to pump!
Q:Pump adapter joint net outside tube, what is the principle?
First, the working principle:Fire pump adapter is connected with the public security fire department fire engine or motor fire pump fire water transport through the fire pump adapter interface fire water supply pipeline to the buildings, the fire hydrant indoor get sufficient pressure to solve the problem of water shortage and other difficulties or because of fire water supply pipeline inside the building due to low water pressure caused by the fire fighting for high-rise building, indoor use and normal operation of fire pumps and intermittent water supply situation in. The installation types include floor type, underground type and wall type.A brief introduction to the two, pump adapter:When a fire occurs, the fire engine pump can quickly and conveniently through the interface and building the adapter in the fire fighting equipment is connected, and the water pressure, so the indoor fire equipment pressure with sufficient water to extinguish, different floors of fire, effectively solves the problem of building fires, fire fighting because of difficulties or indoor fire fighting equipment due to lack of adequate water pressure to the fire.
Q:What is a water pump for?
It is to compress the gas and let out the liquid, such as the bottled water in the life, and to compress the air with a pump to make the water run out
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:The wiper pump is broken. How much will it cost to fix it?
Hello, the wiper motor is broken, can only be replaced to solve the problem, different models of price difference is too large, general average car about 60-80. You can go to a few repair shop to ask, OK, you can also match the city or Taobao purchase.
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:What are the conditions for the series and parallel connection of the pumps?
Parallel pumps: the pump is required to lift the same. This effect is to increase traffic.Pumps in series: requirements are similar to the flow of water pumps. This allows you to increase the total head and recommend adding small pressure tanks during the series connection.
Q:Horizontal pumps, vertical pumps, which kind of expensive?
The same type of single pump is cheaper than verticalMultistage pumps are the opposite
