Q:Fire pump room is required to set up water pump control room?
You can't set it up.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.Fire pump for fire as the name implies, pump, fire pump is the introduction of foreign products, according to different classification, divided into different types to its sealed, no leaks, corrosion-resistant characteristics, widely used in environmental protection, water treatment, fire departments for pumping all kinds of liquid, no leakage, no pollution is to create civilization workshop civilization, the ideal pump factory and pump type fire control system are similar, only the head and the flow are different. The selection of fire pump should be based on the technological process, water supply and drainage requirements, from five aspects to consider. Fire pump performance and technical conditions meet the requirements of the Atlantic pump standard "fire pump performance and test method" standard.
Q:Why does the water pump leak?
The sealing ring is invalid
Q:Does the IP55 indicate the lift on the water pump nameplate?
IP55 represents the waterproof and dustproof rating of the motor
Q:Water pump "rated lift: 6m" what do you mean?
Popularly speaking, "lift head" is the ability of water pump to lift water. 6m means that the pump can pump water to the height of 6m.
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:Relationship between power and flow of sewage pump
If you simply want a formula that satisfies your everyday application, the following will meet the requirement:N= y QH/1000,The severe gamma liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / second; divided by 1000 is the change of power W to kW;Attachment: gravity is the density of an object multiplied by gravity. Acceleration is expressed as a force in terms of the weight of a unit;The formula is applicable to situations where the calculation is not high and applicable to any liquid known or known to be heavy;The formula is reduced to three simplifications:1, ignoring the pump impeller, shaft and other friction losses;2, ignore the pump flow loss;3, ignore the pump pipe, as well as mechanical heat loss;As a result of the above three loss in the process, material, liquid delivery the same condition can be simplified as a coefficient, then adjust the ETA - efficiency coefficient, can satisfy the application value.The deduction principle of this formula is relatively simple, and the mechanical work of the pump is considered to be transferred to the mechanical energy of the liquid completely;That is, N= gamma QH, at this time, all the mechanical energy that water possesses;Electrical and mechanical energy conversion efficiency exists, then divided by the conversion efficiency ETA is obtained;N= y QH/1000;Special attention is needed. - though the efficiency represents the input electric energy and water energy ratio; but the relationship between the two have many effects, the structure of pump, pump body, liquid material feeding. If the above formula is used to estimate, it should be revised according to the actual situation.
Q:Why does the pump head decrease when the pump flow rate increases?
When the power increases to a certain extent, can not be increased, so when the flow increases, the head can only be reduced
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:The efficiency of water pump frequency conversion is very low, why?
Variable frequency pump running normally, its flow and lift is lower than the power frequency operation, that is for sure. The so-called power frequency operation is full speed operation, of course, the head and flow is the highest.Frequency conversion is mainly to save power and reduce the running loss of equipment. The so-called efficiency, but also by the correct selection, the actual pump head and flow as close as possible, the actual working conditions for the best.
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.
