Product Description:

Product introduction:
CDL/CDLF is a kind of vertical non-self priming multistage centrifugal pump, which is driven by a standard electric motor .The motor output shaft directly connects with the pump shaft through a coupling. The pressure- resistant cylinder and flow passage components are fixed between pump head and in-and outlet section with tie-bar blots. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be quiped with an intelligent protector to effectively prevent it from dry-running,oul-of-phase and overload.

Application:
CDL/CDLF is a kind of multi-functional products.it can be used to convey various medium from tap water to industrial liquid at different temperature and with different flow rate and pressure.CDL type is applicable to conveying non-corrosive liquid, while CDLF is suitable for slightly corrosive liquid.
1 .Water supply: Water filter and transport in water works, boosting of main pipeline, boosting in high-rise buildings.
2.Industrial boosting: process flow water system, cleaning system, high-pressure washing system, fire fighting system.
3.lndustrial liquid conveying: Cooling and air-conditioning system, boiler water supply and condensing system, machine-associated purpose, acids and alkali. 4.Water treatment: filtration system, reverse osmosis system, distillation system,separator, swimming pool
5.Irrigation: Farmland irrigation, spray irrigation, dripping irrigation.


Work Conditions:
Thin, clean, non-flammable and mon-explosive liquid containing no solid granules and fibres.
Liquid temperature: Normal temperature typei-15℃ -+70℃
Hot water type:+70℃ -+120℃
Ambient temperature: up to+40℃
Altitude; up to1000 m

Q:How many kilograms of water pump are there in the automatic washing machine on the market?
Longer service life. Automatic switch water pump, car wash automatically open and stop, easy to operate, not easy to bad, repair rate is low!!!
Q:Why can't the centrifugal pump pump the vacuum?
Characteristic equation of centrifugal pumpStudy the effect of fluid on centrifugal pump to obtain energy.The experimental condition of u is that the ideal fluid of unit weight bends the flow between blades at infinity.U investigated the mechanical energy balance of the fluid between the adjacent two inlet and outlet sections, that is, the relationship between theoretical pressure head and theoretical flow.
Q:5 floor water pressure is too low, what kind of water pump is better?
Pipe blockage, leaks, or throttling devices are not opened. This can be tested on a pipe with a pressure gauge;Water pump is equipped with power source, power or speed does not match, check the pump and power end nameplate, power end of the pump power is generally 1.1.5 times;
Q:How many pumps does the 80cm tank use?
For example, you are 80 cm tank, assuming you are 40 cm wide, the water surface is also 40 cm, then the final count by 80X40X40=128000 cubic centimeter, that is, 128000 ml.
Q:Metering pumps related matters
1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal
Q:What are the important parameters of the pump?
The head is the unit weight of liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid used, referred to as meters.Speed nThe speed is the number of revolutions per unit time of the pump shaft. It is indicated by the symbol n. The unit is r/min.Cavitation allowance NPSHCavitation margin, also called net positive suction head, is the main parameter to indicate the cavitation performance. The cavitation margin has been expressed by delta H at homePower and efficiencyThe power of water pump usually refers to the input power, that is, the power transferred by the prime mover to the pump shaft, so it is also called shaft power. It is expressed by P;The effective power of the pump, also known as the output power, is expressed in Pe. It is the effective energy obtained by pumping the liquid out of the pump in unit time
Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
For example, once you sprinkle water from the tank to the ground, one shot of water is 1000 milliliters, which is equivalent to displacement, once (pump turn) 1000 ml.,
Q:How many square cables does the submersible pump for 7.5KW need?
I=P/ (1.732Ucos phi) =7.5/ (1.732X0.38X0.85) =13A (calculated according to three-phase city power, power factor 0.85).
Q:Pump unloading in hydraulic transmission,
Unloading is pumping oil directly back to the tank, the pressure is very low, energy saving
Q:How can the submersible pump level meter be connected?
The company actively introduce international advanced production equipment and production technology, with its strong technical force, perfect equipment conditions and rich manufacturing practice, constantly development and improvement of pump products, according to the needs of users of innovative products, stable performance, excellent quality, many products export part countries and regions
