The pump is stable in operation, low in noise, reliable in quality, beautiful in appearance, small in volume, light in weight and convenient in transportation. It is an ideal green and environmental protection energy-saving pump. The demonstration significance of CDLF vertical multistage centrifugal pump: the product characteristics of CDLF vertical multistage centrifugal pump: 1. The CDLF vertical multistage centrifugal pump adopts excellent hydraulic model and advanced manufacturing technology, which greatly improves the performance and service life of the pump. 2. because the shaft seal of CDLF multistage centrifugal pump is made of cemented carbide and fluororubber, the reliability of pump operation and the temperature of the conveying medium can be improved. 3. The overflow part of CDLF vertical multistage centrifugal pump is made of stainless steel plate stamping welding, which is suitable for mild corrosion medium. 4. The CDLF vertical multistage centrifugal pump has compact structure, small volume, light weight, low noise, remarkable energy saving effect and convenient maintenance. 5. The inlet and outlet of CDLF centrifugal pump is located on the same horizontal line of pump base, and can be directly used in the pipeline. 6. Zilmet CDLF multi-stage centrifugal pump adopts standard motor, and the user can easily equip the motor according to the needs. 7. intelligent protector can be equipped according to the needs of users, effectively protecting the pump from idling, phase shortage and overload. The operation conditions of CDLF vertical multistage centrifugal pump: thin, clean, non combustible, explosive liquid without solid particles or fibers. Liquid temperature: normal temperature type - 15 ℃ to +70 ℃; hot water type +70 ℃ to +120 ℃; environment temperature: maximum +40 ℃; altitude: up to 1000m. The performance range of CDLF vertical multistage centrifugal pump: flow: 1-22 m3/h; head: 6-232 m; power: 0.37-15kw; speed: 2900 rpm; diameter: φ 25- φ 50; temperature range: 15 ℃ - +120 ℃; application of CDLF vertical multistage centrifugal pump: water supply: water plant filtration and transportation, water plant partition water supply, main pipe pressure, high-rise building pressure. Industrial pressure: process water system, cleaning system, high pressure flushing system and fire fighting system. Industrial liquid transportation: refrigeration air conditioning system, boiler water supply and condensation system, machine tool supporting, acid-base medium transportation. Water treatment: ultrafiltration system, reverse osmosis system, distillation system, separator, swimming pool water treatment system. Irrigation: farmland irrigation, spray irrigation, drip irrigation. Model spectrum of CDLF vertical multistage centrifugal pump: installation of vertical multi-stage centrifugal pump of illon CDLF: 1. CDLF vertical stainless steel multistage centrifugal pump shall be installed vertically on the ground, and enough cold air shall be installed to enter the motor cooling fan. The arrow at the bottom of the pump indicates the direction of filling through the pump. 2. in order to minimize the noise that may be generated by the pump, it is better to install anti vibration clamps on both sides of the pump and between the foundation and the pump body. Butt flange, washer, bolt and pje pool are supplied as auxiliary parts and must be ordered separately. When cleaning, repairing or replacing the pump is required, isolation valves shall be installed on both sides of the pump to prevent drainage of the system. The installation pipeline of multistage centrifugal pump shall avoid air blockage, especially on the suction side of the pump. The piping shall be installed so that any tension caused by temperature changes does not affect the pump. If the pump is installed on long pipes, it shall be properly supported at the front and back of the drawings. 3. if the multistage centrifugal pump is blocked by stones, leaves, twigs and other trees. Measures should be taken to prevent such things from happening. Install the screen on the suction pipe. 4. in some installation cases, the drain pipe has been installed horizontally or tilted downward by the pump, so the water in the pump will or must flow out regularly, and the pump shall be protected from idling the impeller. This can be avoided by installing a bad pipe with a vacuum valve near the pump. The highest point of the circuit shall be at least flush with the connecting plate of the pump motor. In this way, the drain can be drained from the pump alone and vice versa. 5. when the drain valve is closed, it is forbidden to operate the pump because it will cause temperature rise / steam formation in the pump, which will cause damage to the pump. If there is any danger to the operation of the pump when the drain chamber is closed, connect it to the outlet with a bypass or drain to ensure that the minimum amount of liquid flows through the pump. For example, the drain can be connected to the water tank. 6. minimum number of Walem CDL and CDLF light multistage pumps. Example of CDLF vertical multistage centrifugal pump: typical high pressure flushing system diagram example. This installation method shown in the figure is used in cases where "minimum flow" through the pump cannot be guaranteed. 1. the flow switch of light multistage centrifugal pump will protect the pump from high heat damage when the flow is too small. 2. in the device of transporting slightly polluted water, a filter screen of light multistage centrifugal pump is installed to protect the liquid flow switch. Note: the above measures are unnecessary in the device with stable liquid flow and minimum flow. In equipment with water hammer danger, check valve must be installed at the outlet of pump. Do not use quick closing valves, such as quick closing of the gun, as this spray gun will cause water hammer. The connection between motor and pump shaft is affected, and the pump shaft will break when serious. Electrical connection of CDLF vertical multistage centrifugal pump: 1. The power must be turned off before opening the terminal box cover and removing any pump components. Electrical connections must be made by qualified electricians in accordance with local regulations. The motor junction box must be connected correctly to the power switch. The working voltage and frequency are indicated on the nameplate. Note that the power supply used shall be suitable for the motor. The three-phase motor must be connected to the starter with protection only. 2. the junction box of light multi-stage centrifugal pump can turn 90 ° in turn and stop at four positions. If necessary, use a screwdriver to remove the coupling guard, but do not remove the coupling. Remove the bolts that secure the motor to the pump. Turn the motor to the desired position. Install the bolts and tighten them. Refit the coupling guard so that it is perpendicular to the center of the pump head notch. Electrical connections shall be made according to the wiring diagrams in the terminal box cover. Note: do not start a light multistage centrifugal pump until it is filled with liquid. CDLF vertical multistage centrifugal pump start: 1. When the liquid level of light multistage centrifugal pump is higher than that of closed system or open system at the pump inlet: 1. Close the drain isolation valve and screw off the exhaust screw on the pump head. 2. please pay attention to the direction of exhaust port, and ensure that the water flowing out will not harm or damage the motor or other parts. In hot water installation, special attention should be paid to the scald risk caused by hot water. 3. slowly open the isolation valve on the suction pipe until the stable air flow flows out of the exhaust valve. 4. when starting the light multistage centrifugal pump, tighten the exhaust screw and fully open the isolation valve. 2. when the liquid level of light multistage centrifugal pump is lower than that of the pump inlet open system: 1. Before starting the pump, the suction pipes and pumps must be filled with liquid and drained. 2.CDL2，4(CDLF2，4，8，16) 3。 Close the drain isolation valve. As shown in Figure 7, turn the bypass valve slightly against the stop. 4. remove the filler plug, fill the liquid from the filler until the suction pipe and pump are fully filled with liquid, and then retighten the bypass valve. 5. when starting the light multi-stage centrifugal pump, replace the filling plug and tighten it. 3. check the rotation direction when starting the light multistage centrifugal pump: 1. Do not start the pump to check the direction of rotation until the light multistage centrifugal pump is filled with liquid. 2. when checking the motor running direction, the coupling shall not be disassembled for inspection. Because when the coupling is removed, the position of the shaft needs to be adjusted. The correct direction of rotation is indicated by the arrow on the pump head or motor fan cover. From the fan, the light multistage centrifugal pump should be turned counter clockwise. 4. start of light vertical multistage pump: 1. Before starting the light multistage centrifugal pump, the isolation valve on the suction side of the pump shall be fully opened, and the isolation valve on the discharge side shall be almost closed. 2. when starting the light multistage centrifugal pump, the pump shall be discharged by unscrewing the exhaust screw on the pump head until the stable liquid flow flows out of the exhaust hole, and then tighten the exhaust screw. Pay attention to the direction of the exhaust hole to ensure that the flowing liquid will not harm or damage the motor or other parts to the person. In hot water installation, special attention should be paid to the scald risk caused by hot water. When the piping system is filled with liquid, slowly open the isolation valve until it is fully open. When the pump contains air liquid, it is better to exhaust regularly. To drain the pump, loosen the exhaust screw on the pump head during operation. Maintenance and start-up frequency of CDLF vertical multistage centrifugal pump: maintenance of CDLF vertical stainless steel multistage centrifugal pump: 1. Before the vertical multistage centrifugal pump starts to work, it must be found that the pump has no power supply and the pump cannot start suddenly. 2. the bearing and shaft seal of light multi-stage centrifugal pump need not be maintained. If the pump does not need to be drained for a long time, a coupling protection plate can be removed and a few drops of silicone oil can be injected into the shaft between the pump head and the coupling. This prevents the sealing surface of the shaft from sticking. 3. when installing coupling guard, pay attention to their vertical alignment in the pump head slot. Motor bearing of CDLF vertical stainless steel multistage centrifugal pump: 4. Motors without lubrication nozzles do not need maintenance. Motors with lubricating nozzles shall be lubricated with high temperature lithium grease. 5. if zilmet light multi-stage centrifugal pump is suspended for a long time, it is recommended that the pump and motor should be cleaned and lubricated once they are put into use. 6. when the pump is put in use during frost, water should be discharged to prevent damage and rupture. Remove the drain plug on the base by unscrewing the exhaust screw on the pump head, so that the pump can be drained. After drainage, the unloaded parts shall be reinstalled in place or properly kept. Start and stop frequency of Shanghai titanon CDLF vertical stainless steel multistage centrifugal pump: motor with power less than 4kw, and starting frequency shall not exceed 100 times per hour. Other motors shall not be started at a speed of more than 20 times per hour.

Well, the above is the introduction of the application of CDLF vertical multistage centrifugal pump. Next, let's talk about several main reasons for the excessive power consumption of CDLF pump:
What is the reason why the water pump consumes too much electricity? The analysis mainly includes the following six points: 1) the total head does not match the pump head; 2) the density and viscosity of the medium are inconsistent with the original design; 3) the pump shaft is inconsistent with or bent with the original motor axis; 4) friction exists between the rotating part and the fixed part; 5) the impeller mouth ring is worn; 6) the seal or mechanical seal is not installed properly. OK, the above is the application of CDLF vertical multistage centrifugal pump. Please contact Shanghai Longya multi-stage centrifugal pump operator for more introduction and price.
