Fountain pump by water pump, submersible motor (including cable) four major part, water pipe and control switch. Submersible pump is single-suction multi-stage vertical centrifugal pump; Submersible motor is airtight filling water wet, vertical three-phase squirrel cage induction motor, the motor and pump through a claw type or single bond drum coupling directly; Motor materials using DR470 cold-rolled evening steel pieces, increase the number of turns of windings and diving line of wire, cable in three phase four wire type JHS fountain cables, impeller increases the loose prevention device, motor chamber adopts imported antirust enamel, through the above structure improvements make submersible pump inertia small, thus the response speed, bearing the axis, to improve the insulation level, so as to meet the needs of the special music fountain, frequent starting.

Fountain pump shell, material flow components and external parts adopt cast iron or stainless steel (304, 316, 316 l), and the product also retained the original fountain pump performance. Open pump, the suction pipe and pump must be filled with liquid. After open pump, high-speed rotating impeller, the liquid with the blades rotate together, in under the action of centrifugal force, fly away from the impeller to injection, injection of the liquid in the pump shell gradually spread of indoor speed slow, pressure increase gradually, and then from the pump discharge, the discharge pipe flow.

Fountain pump conditions of use

1. The pumps should be fully immersed in water running, diving depth of not less than 0.5 meters, not greater than 5 m.

2. Environmental water temperature should be higher than 40 ℃.

3. The working medium for no corrosive water, sediment concentration is not more than 0.1%, PH value of 6.5 ~ 8.5.

4. The power supply should be three-phase 50 hz, rated voltage of 380 v, the power supply voltage must be in the range of 342 ~ 420 v.

5. Electric pump should be near the rated head within the scope of use.

6. Pumps should configure corresponding start protector, reliable grounding.

After today for everyone to introduce bearing assembly quality analysis and judgment. A. Dimensional accuracy out-of-tolerance inside diameter, outside diameter size is out-of-tolerance may in the finished product inspection, the main reason: before the process of product targets. Check assembly environment temperature change is big. Standard parts and ring temperature was not enough. Grinding use standard components and finished goods inspection is unqualified. Bearing inside diameter size is too large, shall be awarded for the unqualified products, inner ring scrap. Inside diameter size is too small, should be convicted of unqualified products, but can rework grinding, make it become a qualified products. Bearing outside diameter size is too big, can pass to grinding, make its become qualified. But the diameter size is too small, should be convicted of unqualified bearing, outer scrap.

QSPF100-5-2.2 stainless steel fountain pump

Pumps for a long time need not when, immediately release the motor water, wipe the surface clean and coated with anti-rust oil, in a relatively clean, dry, no chemical corrosion. Motor chamber filled with water, it is strictly prohibited in the temperature of 0 ℃ and the following conditions, otherwise you must put the net cavity water, in case the frost crack motor.

Among them: when drainage lavatory need to confirm is: at this time must be clear from the concept of the wall. Wall is apart from the so-called refers to the ground (lavatory) from center line to complete the distance of metope, water is not the center line of the lavatory drains from the lavatory tank back vertical distance. When water lavatory need confirmation is rank: at this time must be clearly the concept of distance. Is refers to the lavatory drain after the center line is apart from the completion of the distance of the ground, in the choice after good lavatory, be sure to water tank inlet pipe and Angle valve will use with matching purchase together. Forget to purchase products tend to have a lot of customers, let the decoration workers assemble themselves, the result often cause Angle valve leakage and make consumers suffer losses, so the product of form a complete set of purchase is very important.

QSP stainless steel fountain pump features:

1, adopt stainless steel material, improve the pump.

2, when using the material to prevent impeller impeller impeller is loose.

3, leakage protection measures: the potential grounding device.

4, on the basis of the original common pump, according to the requirements of the fountain pump company after many experiments, continuous development in technology, continuous improvement on processing materials, can make the fountain pump frequent starting, entirely suitable for the use of music fountain.

5, pump adopt stainless steel mesh cover, three phase four wire cable.

6, stainless steel fountain pump as the function of automatic filling.

7, the motor for the circulation cooling water filling type.
