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:Double floor sewage pump circuit diagram of a small problem: Question 4 when you need backup, you need to switch the SA switch, but where you want it. For example, when the 1# pump is running and does not reach the high water level, the 2# pump will not operate. If SA is placed in the left position, 21 and 22 are connected, and the KT is electrically delayed, and the KAB action causes the 2# pump to function. After the KAB operation, the KT will be disconnected, restored to the ready state, and also convenient for KT to restart the power on time, and also avoid the time relay to work on a long-term basis.

Q:What are the differences between the sewage pump and the clean water pump?: The main difference between the sewage pump and the clean water pump is that:Impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.

Q:If the suction pump does not have enough suction range, you need to add a vacuum pump to increase the suction stroke. How do you install the suction pipe of the vacuum pump? Water pump impeller is not closed, it is normal that the vacuum pump is unable to pump suction pipe to a vacuum, is it because the water pump outlet pipe connected to the role of the check valve? But the water pump, outlet pipe, check valve sealing performance can achieve the function of non leakage?: The role of the check valve:"[the water pump impeller is not closed" refers to the pump suction pump before the water without water inlet pipe and water outlet pipe gas should be connected] is a connector, a connector, still can make the level surface, in order to prevent the water flow along the pipe, until it reaches the level of the flush, then increased check valve, or pumping up water will not leak?Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".....

Q:How many kilograms of water pump are there in the automatic washing machine on the market?: High pressure pump pressure can reach 4--8kg, flow 5 liters, work current 4 or so.

Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?: Working pressure - the actual working pressure of the motor, that is, the pressure of the input oil. The difference between the motor inlet pressure and the outlet pressure should be calculated.Rated (nominal) pressure under normal working conditions, according to the test standards for continuous operation of the maximum pressure, that is, the rated pressure, more than the maximum pressure is called overloading.

Q:What's the meaning of the pump head in the water pump, please advise, thank you: According to China Wikipedia network, the basic components of the water pump: motor, coupling, pump head (body) and chassis (horizontal).Pump is generally composed of pump body and pump head, in which the pump body refers to the spiral case, impeller, bearing, oil shell and sealing assembly, etc., the pump head refers to the impeller, bearings, oil ring and sealing rotating parts (including shaft), etc..

Q:Types and differences of pumps: Depending on the flow of the fluid, they can be subdivided into the following:Classified centrifugal axial flow type mixed flow tubular flow typeThe basic principle of impeller centrifugal force generated by the high-speed rotation of the fluid energy rotary vane extrusion propulsion of the fluid increases the pressure to get the energy mix and energy principle of centrifugal and axial and centrifugalSuch as: central air conditioning centrifugal fan, central air conditioning or cold storage axial flow water pump, mixed flow water pump, domestic air conditioner, indoor fanWorking principle of pump and fanI. the working principle of centrifugal pumps and fansThe centrifugal force generated by the high-speed rotation of the impeller fluid power, namely fluid through the impeller, pressure and kinetic energy can be improved, which can be transported to the height or distance. The impeller is arranged in a spiral shell, when the impeller rotates, the fluid axial inflow, and then turn 90 degrees into the impeller and the radial outflow impeller. Continuous rotation of the impeller inlet in the form of vacuum, so that the fluid continuously by the pump suction and discharge.

Q:Do you have a suction pump higher than 9 meters?: Pump rated suction generally 7 meters or so, it is estimated that no one calibration pump suction stroke 9 meters. Calibration suction range of 9 meters is not reliable.

Q:What are the important parameters of the pump?: Pump parametersFlow rate QFlow is the amount of liquid (volume or mass) that is pumped out in unit timeVolume flow is expressed in Q units: m3/s, m3/h, l/s, etc.

Q:How long does the fine stone pump need maintenance? What should I pay attention to?: Check the line from the relief valve to the cylinder inlet to ensure that there is no external drainage or deformation due to impact and wear and that the connections are complete and fully tightened. - replace any damaged pipe immediately. - change the original settings strictly: all adjustments and calibrations can only be done by professionals. - no fucks hydraulic components, otherwise manufacturers on product warranties and liability shall not be responsible for. A warning because the hydraulic oil can reach very high temperature, there is the danger of burns, so open pipe fittings should take appropriate protective measures. Any replacement parts must conform to the level specified by the manufacturer. 8.2 check lubrication grease pump in oil at any time to ensure adequate and clean the lubrication pipeline joints without overflow phenomenon. Check the lubrication of the running parts at any time, and find the parts which lack oil, and check them immediately to prevent accidents. - check that the centralized lubrication system is effective daily. When the grease pump is empty, the grease added is often not easy to pump out because of the bubble. In this case, open the outlet of the pump, run the grease pump until the grease is re flowing, and then connect the pipe
