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

4. Operation conditions:

Thin, clean, non-flammable and non-explosive liquid containing no solid granules and fibers

medium temperature: -15°c~+120°c

Capacity range: 1~180 m3/h

Head range: 6~305 m

Q: You'd better point out the details.... There are 2 best ways of experience and formulaCan you say a simple point, such as multi-stage pump, when the pump is higher than the motor, 30 wire is the next mouth how to do?: Looking forAlignment means the position of the center of rotation of the pump and motor so that they are in the same line.At least three times after the initial installation or after installation:

Q: The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,: A standard atmospheric pressure can be 10.33 meters to 30 meters of water, suction is atmospheric pressure there are three standard atmospheric pressure so high? This is impossible in general, remove the vaporization removed 0.5 meters critical yo,

Q: 5 floor water pressure is too low, what kind of water pump is better?: Installed pump flow, lift did not meet the requirements, this will need to re type selection, calculation;

Q: What is the minimum continuous flow of a pump?: The minimum continuous steady flow can be obtained by test and, in general, the pump supplier will indicate(2) minimum continuous heat limited flow (.API) provides minimum continuous heat limit flow, which means the minimum continuous flow that the pump can maintain and that its operation is not impaired by the temperature rise of the liquid being pumpedMinimum continuous heat limited flow can be calculatedIn the formula, the Pe amount of the fixed axis power is.KW;P pump medium density, kg / m3;

Q: If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?: What will happen then? The aquarium glass is an insulator. The water in the fish tank has the same potential as the live wire, and the fish is like a bird standing on the fire line. No electricity flows through their bodies, so they won't get electrocuted. But if you put your hands into the water, you will get an electric shock, because the line voltage through the water, then your body and the earth to form a loop, current flowing through your body you will get (of course, if you stand on the insulator does not get an electric shock)

Q: Is the vacuum pump air compressor?: No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.

Q: What is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you: There are many ways to change the variable pump flow: by changing the eccentricity to change the piston stroke length (radial piston pump, the frequency change principle) motor speed to adjust the flow (such as gear pump flow control principle).

Q: Harm of air pump and pump: Centrifugal pump situationEmpty pump is divided into two kinds, if there is no liquid, then it will cause the mechanical seal of the pump to overheat, wear and even die

Q: How accurate is the metering pump?: Three automatic compensation valve device widely used in diaphragm metering pump, especially with suction height requirements, can only be used by three separate Fujian (safety valve, discharge valve and oil supply valve) compensation device.

Q: Significance of water pump model ISO50-160: According to different working principles can be divided into volumetric pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
