Multistage Stainless Steel Centrifugal Pump

Vertical Multistage Pump

1.Introduction:

CDL/CDLF high pressure water pump is special in high pressure, made of stainless steel 304 or 316, all parts touch with liquid are of stainless steel. The pump is vertical non-self priming multistage centrifugal pump, which drived by a standard electric motor.The motor output shaft directly connects with the pump shaft through a coupling. The pressure resistant cylingder and flow passagecomponets are fixed between pump head and inlet and outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.

2.Applications:

· Urban water supply and pressure boosting

· Industrial circulating system and processing system

· Water supply for boiler, condensing system, high-rise building or fire fighting system.

· Water treatment and RO system

· Cooling water system

3.Electric motor:

· TEFC motor,

· 50HZ or 60HZ 220V or 380V

· Protection class: IP55, Insulation class: F

Q:What is a water pump coupling device?: The automatic coupling device of the water pump coupling device has compact structure and small occupation area. The sump pump works because it is submergedThe utility model can be directly installed in a sewage pool, and no special pump house is needed to install a pump and a machine, thereby saving large amounts of land and infrastructure expenses

Q:How many millimeters is the diameter of the water outlet of the four inch pump?: If it is a centrifugal pump, the nominal diameter of the outlet is less than 4 inches, there is a conical short tube to enlarge the standard 4 inch outlet flange, from here, is the standard 4 inch flange connection.

Q:What is the difference between centrifugal pump and self suction pump? Which is better?: If the centrifugal pump in full before the start of the shell of the gas, then start after the center of the impeller was thrown in the gas can not be large enough to form the vacuum, so that liquid in the bath can not be sucked, so the centrifugal pump to start before using foreign liquid in the pump housing space filling

Q:Harm of air pump and pump: Minimum starting current when centrifugal pump of such a small impact on the grid but long closed operation will make the liquid in the pump to the pump overheating temperature is too high will lead to the problem of the seal to a certain temperature will cause deterioration of oil bearing bearing caused by excessive wear and even bite dead

Q:What does centrifugal pump mean horizontally?: Centrifugal pump horizontal opening meaning: pump shell and pump body along the pump blade horizontal central line is divided into the upper and lower halves, so that the maintenance of pump leaves when the pump top cover can be separated from the pump and bearing as a whole. No need to remove the pipe.

Q:What is the pumping property of concrete?: Pumpable concrete slump is generally greater than 160mm, the mortar content is too low, the maximum aggregate size of not more than 1/3 of the diameter of the pump pipe, sending process segregation, plugging in the pump.

Q:Hydraulic pump displacement refers to the pump shaft what?: Displacement of the hydraulic pump refers to the axis of each turn, the volume discharged, called displacement, the unit is ml (ML),

Q:What's the word "pump"? Is that what advocates mean?RT: What is a "fan"?In recent years, the term "fan" often appears on the newspaper Web page, whether it is a team, a singer, a sports car and a toilet, all of which have their own fans

Q:The working principle of magnetic pump: Working principle of magnetic pumpN of the magnet (n is even) arranged according to the laws in the magnetic clutch assembly inside and outside the magnetic rotor, the magnet part consisting of magnetic coupling system. When the inside and outside the two poles in different relative displacements, two poles between the angle phi = 0, the lowest energy magnetic system; when rotates to the relative displacement is two poles, pole angle between phi = 2 pi /n, the magnetic system of magnetic energy. Remove the external force, due to the magnetic system of magnetic poles repel each other, magnetic magnet will return to the lowest energy state. So magnets in motion, driven by the magnetic rotor.

Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?: Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.
