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 about the depreciation of vacuum pumps?
(five) electronic equipment, for 3 years.The depreciation period of a vacuum pump can be calculated for 5 years. The expected residual rate is generally 5%, or it can be estimated by itself.
Q: Troubleshooting of diaphragm pump
In the application of the pump, these conditions are likely to encounter. Each situation can be divided into several possible reasons. This guide lists the causes of failures and gives appropriate corrective maintenance measures. The meaning of all the specific terms in the guide is listed later.Air valves - copper or stainless steel valves are bolted to the center of the pump by four bolts.The piston aluminum cylinder is enclosed in the air valve to control the gas flow.Cavitation - because the pump inlet for the amount of fluid to reduce or lack, the pump discharge is less than the amount of quantitative. In fact, the fluid chamber is full of fluid before it is discharged.Static pressure drop - the inlet pressure from the pump centerline to the free point - the inlet is measured in pounds, including the specific gravity and velocity of the fluid.
Q: What is the pump lift voltage? And how to suppress the pumping voltage rise?
[pump voltage] when braking, in the motor winding series resistance, motor equivalent to the generator, the energy will be converted to electric energy consumption in the series resistance. This method is widely used in all kinds of motor braking, and frequency conversion control is also used. From high to low (zero speed), then the electrical frequency changes quickly, but the rotor of the motor with the load (production machinery) mechanical inertia, could not stop quickly, resulting in the back EMF (EU voltage) motor is in the state of power,
Q: What is the principle of a turbopump?
The working conditions of the turbine are different from those of the medium used, so the structure of the turbine is varied, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) mounted on a turbine shaft with blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work.
Q: What is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you
Variable pump variable refers to the flow can be changed to distinguish from the constant flow of quantitative pumps.
Q: What are the starting and stopping procedures for centrifugal pumps?
The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
Q: What is a positive displacement pump? He Weizheng displacement?
The principle and structure of positive displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow.
Q: What is the cause of the damage of pump bearings?
In high-speed equipment, the most likely damage to bearings is high temperature.
Q: No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?
Non negative pressure variable frequency water supply means no negative pressure superposed water supply equipment. When running, it is connected directly to the water supply pipe. Always test the pressure of tap water pipe network and water supply pipe network pressure control system, when the water pressure is lower than the pressure required by the user, the frequency conversion device based on water automatically control the pump speed through the steady flow compensator of water balance, maintain a constant pressure water supply. In the multi pump system, the control system can automatically dispatch the water pump according to the water consumption. It can balance the working time of the pump and ensure the pressure of the water supply. When the water supply pressure satisfy the required pressure, the system automatically stops the pump by the external water supply pipe network directly. CJWFG-DYG non negative pressure superposed water supply system:
Q: How to calculate the motor power of metering pump?
Two Hydraulic power, metering pump rated flow (L/H) X, maximum pressure (Barg) / 36000 = kw
