Product Description:

S single stage double suction centrifugal pumps are late-model energy-saving horizontally split pumps newly developed by us on the base of the old style double suction pumps at home and abroad.They are used to handle clean water or other liquids similar to water in physical and chemical properties.medium temperature not exceeding 80 ℃.This series of pumps are applicable for factories,mines,urban water supply and drainage,power stations,farmland irrigation and drainage,and other water conservancy projects.

The instruction of the structure:

  The inlet and outlet of this type of pumps are below the axial lead of the water pump and are vertical with the axis line. When repair and examination, there is no need to disassemble the inlet, outlet pipe and the motor. Seeing from the direction of driving, the pump is circumrotating clockwise. (We can change it into counter-clockwise).
  The main components of the pump are: pump body; pump cover, impeller, axis, balanced suction seal loop, axial bush, and etc.
  The pump body and pump cover consists of the working room of the impeller. On the water inlet flange and outlet flange, there is pipe tap for installing the vacuum meter and pressure meter. Under the inlet flange and outlet flange, there is pipe tap for pouring the water.
  The impeller after quiet balance checkout is fixed on the axis by axial bush and the axial bush nuts on the both sides. Axile nuts can adjust the axial position.
  The pump axis is supported by two single low annular ball bearings. The bearing is in the bearing body, installed on the two ends of the pump body. Lubricate it by butter.Balanced suction seal loop is used to reduce the water in pressure room of water pump leak to water jet room.
The pump is directly driving by flexible shaft coupling. It also can be drove by gas engine.
The axis seal is flexible sealant (We can adopt mechanical seal structure).

Q:What's the submersible pump?
Centrifugal pump, a general motor and pump body is one, you can pump the whole pump into the water
Q:The car water pump is broken. What are the symptoms?
Car water pump damage, water temperature will rise sharply
Q:How large is the starting current for a 1.5 kW submersible pump?
The starting current is 2-7 times the power
Q:Water pumps are always pumping water, what's the matter?
First check whether the water pump suction gas 2 check the negative pressure of the pump suction is too low 3 check whether the water pump 4 no problem of opening the pump head to check whether the water pump impeller damage
Q:Why can't vertical water pump use spring shock absorber?
Vertical pump can use spring shock absorber, because the bottom of the vertical pump installation area is small, so many people feel that it can not install spring shock absorber, actually not, and now there is a vertical pump can use the shock absorber;Introduction of spring shock absorber for vertical pump;1 、 spring cover and spring seat for the combination of butyl glue and cast iron, and after baking treatment, good weather resistance.2, according to simple installation, bolts can be used to adjust the height and level.3, can be matched with the pedestal design, can be used in various types of machinery and equipment.4, applicable to all types of pumps, fans, air conditioning boxes, pipes and so on.
Q:Fire pump control cabinet installation distance, ground height should be how much?
30MC is fine. There are no definite rulesSome drawings of the introduction is explained, because the drainage of the water pump in the case of clogging, may be submerged into the water pump control cabinet, causing some unnecessary trouble
Q:What is the reason for the overload of the water pump indicator?
Hello friend, pump overload shows that the water pump current increases, the power supply phase and water pump load becomes larger.
Q:What is the reason that the centrifugal pump outlet pressure decreases and the operating current increases?
Export pressure reduction generally 2 reasons: 1, blade wear, 2. mechanical seal leakageThe increase of electric current should be caused by severe wear of the friction pairs of mechanical seals, resulting in increased resistanceIt is suggested that mechanical seals and blades be changed.
Q:The efficiency of water pump frequency conversion is very low, why?
There is a running curve for the fan and water pump.Enough is enough
Q:How do I know the pump pressure?
That is, the rated pressure minus the pipe loss, and then less inlet pressure (generally suction pump inlet pressure is negligible), that is the working pressure.The head of a centrifugal pump is also called the pressure head of a pump. It is the energy gained by the pump of the unit weight and the fluid. Pump head size depends on the structure of the pump (such as the diameter of the impeller, the bending of the leaves and so on, speed. At present, the pressure head of the pump can not be calculated accurately in theory, usually measured by experimental method.
