QJ Deep Well Pump Construction & Features

--- Compact vertical centrifugal multi-stage design with perfect standardization and generalization, easy operation and convenient maintenance.
--- A complete electric submersible pump includes a water pump set, electric motor, a discharge piping, water-proof cable and a control panel.
---Submersible motor filled with clean water for cooling and lubrication. And the pressure regulation switch, located at the bottom of motor, shall automatically operate to balance the pressure fluctuation caused by temperature variations.
---A sand slinger and oil-sealed skeleton are equipped at the upper part of motor to form a closed operating system for the motor, thus preventing any sand to penetrate into the motor.
--- Water injection hole as well as air release hole are designed at the upper part of the motor, and water release hole at bottom (lower) part.
--- Thrust bearing and collar are designed at lower part of motor to stand the weight of the squirrel caged rotor and the axial thrust residual.
--- Water-proof electromagnetic wiring for stator with excellent insulation.

Q:changed the thermostat. it overheats but cools down a heat bar or two idling at stoplights. i filled up the coolant reservoir when i changed the thermostat, drove it about 2 miles(engine was already up to temp when i started) and it overheated. drove it two miles back going about 35-40 and it never went above normal but was still overheating. checked the reservoir and it was empty. stuffed a hose in it and plugged it up with a towel to force water in to see if it was leaking anywhere, no leaks. while running with the rpms up the top hose is easy to squeeze. makes me think water pump. but if i go over 45 it over heats makes me think clutch fan.: So if i understand, you are losing water from your system but no evidence of where it is going. I can think of two options. Heater core, but you may get a coolant smell inside the car, steam on the interior of windshield. You can check this by connecting the heater hoses directly, bypassing the heater core. If it still loses water, look for foamy oil on the dipstick or on the oil filler cap. If present then the other guy is right - headgasket. I would also look into flushing the system, or replacing the radiator - it may be clogged.

Q:Two sewage pumps switch from each other, start with float switch control, the first sump, when the water is full, the first start, the second rotation to second units start, so the cycle of alternating: Do you mean that 2 pumps are used in a hole? With float switch control, plus time relay 24 hours, every 12 hours at will, you set time, seconds, minutes can be

Q:My car overheats in hot temperatures I have try everything except replacing the water pump and radiator how can I tell when its time to change each one and is it a do-it-yourself job: Boomer is right in what to check first. but in this order. Check that the fan is working properly. Check that the radiator is clean and not clogged. Replace the thermostat. Replace the Water pump. Depending on the car/truck, is what dictates how hard it is to do. On older cars (a chevy 350) It takes 15 minutes for a novice to replace, On newer cars it varies greatly, as some are behind the timing belt and all other accesories,(plymouth breeze takes about 15hours for a novice) and some are just as easy as older cars.

Q:quot;A tank has the shape of an inverted circular cone (point at the bottom) with height 10 feet and radius 4 feet. The tank is full of water. We pump out water (to a pipe at the top of the tank) until the water level is 5 feet from the bottom. The work W required to do this is given byquot;I know how to find it if it's a right circular cylinder, but how do I adjust for the changing area? Also would a and b = 0 and 5? Thanks ahead of time!: calculate the amount of water U start with by computing volume of cone: V = 1/3πr?h {r = 4', h = 10'} V = 0.333π(4)?(10) = 167.55 ft? calculate the amount of water remaining in cone after pumping is done: V = 0.333π(2)?(5) = 20.944 ft? calculate the volume of water pumped: 167.55 - 20.944 = 146.6 ft? 1 ft? of water weighs 62.4 lb, calculate weight of water removed: 146.6(62.4) = 9148 lbs The Center of Mass of the water in the cone (when h = 10') is at 1/4 of 10 ft = 2.5 ft high The Center of Mass of the water in the cone (when h = 5') is at 1/4 of 5 ft = 1.25 ft height The Center of C.of M. change = 1.25 + (2.5 - 1.25)/2 = 1.25+0.625 = 1.875 ft If we consider that the Center of Mass of the water removed was at 1.875 ft, All the water removed was then lifted an average of 10 - 1.875 = 8.125 ft Work done = W = (9148)(8.125) = 74,300 ft-lbs ANS

Q:What is the 10KV pump unit?: As the name suggests, the water pump unit is a number of pumps, and 10kV is the voltage level. According to the voltage level, what you call a water pump should be a pump with relatively large power

Q:I am trying to replace a water pump on my ranger and i have all the bolts out. It seems to be stuck i think it is because of the oring around the outside of the pump andy ideas of how to free it?: First of all, make sure you have removed all the bolts. They can be found in the most unlikely places Once you are positive all the bolts are out gently tap on the pump around the perimeter to break it loose. I have changed many water pumps and seldom do they just fall off. Do not hit the belt pulley as you will need to reuse it. I use a ball peen hammer. You don't care if you damage the pump but why ruin a good hammer. If that doesn't work then you need a mechanic. Most probably to find the bolt you missed. .

Q:When the pump is connected in parallel, will the head and flow change?: Depends on how you do it.If you have a pump, the original network is the same, you add a pump, the result is the head and flow increases, the efficiency also changed, increase the number of head and flow, depending on the network characteristics, network characteristics such as steep increase, economy is also poor, which is not recommended. In fact, the actual flow of two pumps plus the actual lift equal, the problem is that the head, flow point of operation has changed.If it is new design, according to the required flow calculation of the required head, according to the head, half of the flow to select the pump, that is, two pumps flow volume, lift equal.

Q:Hi there: my water pump is leaking, and my coolant lelel keeps droping, same problem. Im not sure if coolant flows through the water pump?: While it may seem the water pump is the most likely culprit, I agree with the thermostat solution. Usually, when a water pump fails, it does so gradually, reducing the flow and showing intermittent overheating-usually under load or high temp conditions first. The thermostat, however will cause an immediate overheating situation. You should just go ahead and change the thing anyway, as it's only about five bucks and MAY take 10 minutes to change. It's probably time anyway! Ron Hatton Gadgetman Technologies

Q:on my 92' toyota celica, i got the heater core by pass fixed and also a new radiator because both were leaking, and now my mechanic tells me i also need a new water pump , which can be really expensive! apparently it is leaking water too, so i was thinkng just filling up my car with water before driving until i can afford to get it fixed.. can this shortcut be done to prevent my water pump causing me further problems?: You can do that, but you can't fill it with pure water because in time you'll have only water in the system which can cause problems. Antifreeze also increases boiling point of the water/antifreeze mixture thus protecting the engine... You should always add 50/50 mixture. Anyway, bad pump is generally bad for cooling. It is better to have leaking radiators than bad pump.
