Q:What are the conditions for the series and parallel connection of the pumps?
1, pump series, the two pumps must start and stop at the same time in order to normal operation.2 when the pump is connected in parallel, the two pumps must be equipped with check valve at the same time to operate normally.3, of course, in the election of the pump, should meet the requirements of upstairs said.
Q:4--6 inch deep well pump head? How much per hour out of water?.
Best answerLift pump is the location of the outlet is high, such as wells 5 meters deep, you put the pumping pipe on the bottom, the pump is placed in the vicinity of well, then, the head is 5 meters, the water power how much you buy depends on the pump, the greater the power, the faster the water pumping. The greater the party...
Q:How large is the starting current for a 1.5 kW submersible pump?
1KW about 2 current, so the rated current is about 3A, and the starting current is usually 3-8 of the rated current, that is 9-24A.
Q:What does diving pump 80JYWQ40-15-1600-4 stand for?
Because each manufacturer's label is different, the country although some specifications, but not enforced, so purely from the literal meaning is difficult to explainWe will try to solve the following problems:WQ-- sewage submersible pump80-- outlet diameter of water pump40 - M /h fand flow15 lift M1600 speed, r/min4Kw powerAs for J, Y is rated as sealed form and waterproof gradeI don't know whether it is correct or not
Q:Fire pump control cabinet installation distance, ground height should be how much?
The ground height shall be determined according to the height of the connecting line at the bottom of the control cabinet and the water pump, usually 15~20CM.
Q:The reason why the pump is overloaded
(1) the influence of the basic installation on the equipment.The quality of equipment foundation installation has great influence on the quality of equipment operation. Iron pad placed properly, causing around the foot bolt hanging device, in alignment and fastening process for iron pad hanging, tighten anchor bolts will cause deformation of crosshead slide in the crankcase, the cross head is blocked in the operation of reciprocating load increases when the chute.W5 type reciprocating vacuum pump in the structural design of the cylinder body is cylinder, and the piston, intake and exhaust valve after the heavy weight in the foundation design without considering the cylinder support or hanger, the cylinder will be in a suspended state, because the weight of the crankcase cylinder will cause deformation of the cylinder and slide and slide the concentric degree of difference, so that the cross head is blocked in the slideway and the piston reciprocating operation is blocked during the reciprocating motion in the cylinder caused by the increase of the load.According to the above analysis, inspection found that the vacuum pump end of the cylinder body is slightly lower than the end of the crankcase, cylinder pad iron is low, deformation of crosshead guide foot bolts, the cross head caused by load increases in the slideway and the piston in the cylinder reciprocating operation is blocked, this is one of the reasons causing motor overheating.(2) cylinder and valve coking;The influence of process, cylinder and valve of reciprocating pump is easy to coke, Coke will cause the piston cylinder and piston in reciprocating cylinder operation when the load increases the valve is blocked; coking will cause poor exhaust, the valve closed lax, increasing load, low vacuum degree; clearance at the cylinder piston striking the cylinder will cause coke it will increase the load of cylinder, valve has found the phenomenon of coking, which is mainly caused by the low degree of vacuum.
Q:What is the difference between a sewage pump and a clean water pump? Why can't sewage be pumped with clean water?
The main difference between water pump and sewage pump is that:Impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.2. in order to prevent the wound, water pump impeller design is more simple but not ring pump, equipped with tips, cloth and other debris can be crushed after the pump, and the impeller water pump is relatively complex, but the efficiency will be significantly higher than the former.Why can't the sewage water pump and impeller: because features of key design, resulting in water pump for sewage situation is likely to occur, blocking, winding, wear and corrosion occurs, resulting in damage to pump or scrapped, so water pump can not be used for sewage.Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.
Q:Is it illegal to produce aluminium submersible pumps?
When buying, if you ask for a copper wire or a wire, and don't answer you, it's against the principle of good faith. On the contrary, if you did not ask to buy the water pump with aluminum core, then there is no violation. Because the country does not have any laws and regulations prohibiting the production of aluminum core wire motor, naturally there is no aluminum wire motor as a fake and shoddy products, there is no pre notice obligations.In fact, the aluminum core motor is good, and the price is low, especially in the dry environment of small and medium-sized motors, with good performance. Only used in submersible pumps, because aluminum is easier to damp than copper wire, due to bacteria and other corrosion, and its life is sometimes less than copper wire. But the water pump, aluminum often needs to rewind coil, because of a small submersible pump motor is not good around general scrap.
Q:Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The water pressure (vacuum) is measured by the vacuum meter. The pressure gauge is used to measure the pressure at the water end, and the difference between the two is the lift of the pump
Q:Pump pumping small is what happened?
You are lifting pump or submersible pump ah? Lift pump before pumping water pump, first open the pump and then open the outlet valve, and if there is no pressure, it is time to leave, the sealing performance is not good, check where leakage, and perhaps your pump is broken
