Q:Water pump belongs to power equipment or mechanical equipment?
Ownership of mechanical power equipment in assets
Q:QDX is a submersible pump. What does "X" mean?
It should be small.There is no "downdraft" term;Do not say submersible pumps do not suck, what kind of pump is not on suction, or left and right suction
Q:Can centrifugal pumps be idle? What's the status of the empty transfers?
The centrifugal pump can not be idle, idle will wear packing (packing seal, mechanical seal is almost not damaged) parts, also caused the seal ring, seal, etc. the balance disc wear quickly, and the temperature will rise sharply, causing damage; air transfer effects caused by transient overload voltage of the motor is large, if the motor can not automatically jump to motor will burn.Centrifugal pump mostly rely on the delivery of liquid lubrication and cooling seal of centrifugal pump, idling is empty load, is to open the inlet valve, close the exit valve operation can move, try reversing or empty load operation should be based on the inevitable time, pump specification shall prevail.
Q:What is the reason that the water supply of pump is getting smaller?
1., first look at the external situation, to see whether the water pump is running, the water level is not normal, the water inlet has nothing blocked.2., exclude the external situation, or small water, the pump itself may leak, it will also make water smaller
Q:Pump adapter joint net outside tube, what is the principle?
At once the room after the fire, the internal fire pool once water shortage, the water tank can be within the fire truck hit the water chamber through the pump adapter connected to the fire extinguishing effect.
Q:What does diving pump 80JYWQ40-15-1600-4 stand for?
80: discharge caliber mm;JYWQ: automatic mixing blowdown pump;40: the rated flow m fand /h;15: rated lift m;1600: mix the diameter mm;4: motor power kW.
Q:Water pump part is stainless steel, which part is it?
The part of the pump head, that is, the part of the flow
Q:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?
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
Q:Is the motor with a pump a squirrel cage induction motor?
The motor with water pump is usually squirrel cage asynchronous motorThe squirrel cage asynchronous motor structure and single-phase asynchronous three-phase asynchronous motor of three-phase asynchronous motor motor is similar with a three-phase winding embedded in the stator slot (a single chain, single-layer concentric and cross layer structure of three kinds). The stator winding access three-phase AC power, rotating magnetic field winding current and induced current in the rotor conductor, the interaction of rotor current and air gap induction in rotating magnetic field, and electromagnetic counter (asynchronous transfer cabinet), the motor rotation.Three-phase asynchronous motor. It consists of two parts, stator and rotor. The air gap is between the stator and rotor. Rotor winding is used to generate induction potential, squirrel cage asynchronous motor, Jingjiang Ming art spring factory and produce electromagnetic torque, it is divided into squirrel cage and winding type two. Squirrel cage rotor winding is their winding short circuit, a conductor on the rotor in each slot discharge (material is copper or aluminum), than in the long core conductor, two ends of the iron core with two end ring conductor, the formation of short circuit winding. If the core is removed, the remaining windings are like squirrel cage, so it is called squirrel cage winding.Advantages and disadvantages of squirrel cage asynchronous motorsThe squirrel cage induction motor has the advantages of simple structure, easy manufacture, low cost and convenient operation and maintenance. It is widely used in industry and agriculture as the prime mover of electric drive.Its disadvantage is the poor speed performance and small starting torque, so some other types of motors are used in some situations which require smooth speed regulation and large starting torque.
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.
