QJ Vertical Deep Well Submersible Centrifugal Water Pump




Q:When the pump is running with frequency conversion, the instantaneous power is greater than the power frequency operation, and the actual flow and lift are less than the power frequency. When running, the efficiency is very low. Why?
Pump power frequency operation, speed is rated. Frequency conversion actually adjusts the speed of the pump (the speed becomes smaller), and the flow of the pump moves parallel and downward. As for efficiency, it depends on the operating conditions of the pump. Does it deviate or run to the minimum efficiency position of the flow curve 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?
First, 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. Can also be described according to what you pump model, the pump is divided into piston pumps, screw pumps, impeller pumps and centrifugal pumps.Secondly, under the standard condition, the higher the efficiency of the centrifugal pump, the higher the speed determines the size of the centrifugal force, the higher the speed, the greater the centrifugal force, and vice versa. Plunger pump and screw pump is not the same, the speed of speed and efficiency basically no impact. Third, in addition to buying the pump, you can let the manufacturer give you an FM curve, so you can see the frequency of mediation when the water pump efficiency changes
Q:How do I replace the water pump on a 1996 Mercury 200 hp outboard engine? I have the parts, but want to make sure I replace it correctly. Thanks!
Save yourself a lot of time and trouble and take it to a certified Mecury mechanic.
Q:There is a pump, the rated power is 1200W, but only more than 600 W measured!What's the matter, please?I was not measuring no-load, pumping water in the pool, this work environment should be sufficient to pump full load?Also, is the rated power should not change?Thank you
We must first clear the meaning of rated power; rated power is called the reference numerical electrical power consumption in the voltage conditions specified, and the actual power consumption of electrical appliances is different in different situations, the pure resistance (such as lighting, electric) as long as the voltage conditions, the actual consumption of electric power close to or equal to the rated power, and for appliances like motor, electric power consumption, not only related with the voltage, but also with the relevant load. For example, someone with 200 pounds of energy, then the person in the condition of small meal, maximum load of 200 pounds, but if you take as long as he is 100 pounds, of course he relaxed, he would not say must bear 200 pounds!You measure the pump power is less than 1200W, first you did not mention your use of voltage is not rated voltage, then you don't want him full load, the suction is far less than 8 meters, there is no mention of whether you send water to 50 meters (Yang Cheng), there may be insufficient voltage, and you have don't need it so much power consumption. Of course, one advantage is that it doesn't burn easily. It is easy to burn if it is used at full load.
Q:I want to know the disadvantages of a wind powered water pump and if you have any questions you would ask to someone presenting to you about a wind powered water pump(They should be really hard and smart questions) please include them in your answer.Thanks in advance.
Disadvantage: No wind = no water Questions: 1. What is the minimum wind strength that would cause the pump to operate? 2. What is the maximum wind strength before the water pump needs to be disconnected for safety reasons? 3. What is the frequency of maintenance for the wind turbine and the water pump? 4. What is the conversion ratio from wind velocity to water flow rate?
Q:i am trying to set up a small aqaurium (about 25 gallons) and i am looking for a water pump that will flow water through the aquarium for a period of time and then shut off, and do that like every hour or so. is there such a thing? a water pump with a built in timer so its not running constanly but only every so often? it doesnt need to move alot of water, but i only want it to pump maybe once every hour. thanks for the help
Not sure why you'd want to do this - if you're keeping fish, it would be better to have it run all the time. Anyway, I don't know of any filters or pumps with a built-in timer, but you could get a 24 hour timer and set it to run or shut off when you want just by moving the switches for each hour on or off. With the price of household timers, it would probably be cheaper than to buy a pump with a built in timer.
Q:We had to have our well pump replaced yesterday, how long before the well settles down, and the water tastes like it used to?The company who replaced the pump told us when changing a pump it disturbs the well, and it would take time for everything to settle back into place. Thank you in advance for any and all suggestions.
It will take a few days, you need to get a filtration system installed too. No matter what you need good filters in your pump house.
Q:After the pump has the control box, but also the power distribution box, the control box and the distribution box is not the same box?
1, after the pump has the control box, do not need the distribution box.2. The control box is not the same as the distribution box.Wiring principle is as follows: from the distribution box power supply into the control box, L1, L2, L3 (usually so); from the control box to connect U, V, W to the water pump.
Q:my heater in my 94 ford ranger went out about a month ago today i flushed the heater core and it worked for a while and started going out again after i was driving for 15 to 20 mins. the hose going into the heater core was warm but coming out wasnt. could it have gotten clogged again or could it be something else.
You need to find the Heater Core water valve.. That's the part that works as the TEMP. Control.. Water Pumps don't die slowly..and leak tremendously.. === Sometimes the Water Control valve(seizes).. So..you need somebody to throw the TEMP Lever back and forth..until you can find the valve location.. You may see the cable moving--put not acting upon the valve.. Usually the valve is shot--spraying a lubricant at it won't do anything.. It needs to be removed--too be worked upon.. Also check all the heater hoses for wear--damage--you may need to rebuild that part of the system.
Q:Here are specifications for two water pump sets. I would like to know which one will have more vertical suction.Pump 1:1.5 hp, 98cc Engine, 4 - Strokes RPM 3600 (Engine RPM), Petrol Fuel, Fuel Consumption 700 ml/hour, Delivery (horizontal) 50m, Inlet / Outlet Port (Dia) 1.5x1.5 inches, Output Capacity 48000 Litres / Hour.Pump 2:3.3hp, 163 cc Engine, 4 - Strokes RPM 3600 (Engine RPM), Petrol Start amp; Kerosene Run, Fuel Consumption 700 ml/hour, Delivery (horizontal) 26m, Inlet / Outlet Port (Dia) 2x2 inches Output Capacity 36000 Litres / Hour.which one should I go for.
