General

WDS series horizontal centrifugal pumps have the most outstanding hydraulic performance, the beautiful outline design and the most perfect structure coordination. By utilizing many high scientific methods and the advanced inspection means, WDS type pumps have the unique advantage.Excellent Performance and High Efficiency The advantage of WDS pump comes from the wisdom of many pump experts and gathering the essence of the hydraulic models. There is no hump on the performance curve of pump. Within the scope of wide flow capacity, the pumps can run smooth without disturbing, have high efficiency and lower cavitation.Smooth Running and Low Noise The new driving pattern is adopted in the design of pump, that is, the extended shaft directly drives the impeller. The rotor support parts in the common centrifugal pump are cancelled.No needs coupling. In additional to the elaborating rotor parts, the impeller and the motor use the same shaft to run, so that the smooth operation,less vibration and low noise of pump can be guaranteed.


Description

WDS Structure: 1--- Pump Body 2--- Nut of Impeller 3--- Anti-loose Gasket 4--- Seal Ring 5--- Impeller 6--- Connection Frame 7--- Key 8--- Mechanical Seal 9--- Motor 10--- Base-plate Reliable Operation and Convenient Maintenance The rigidity of shaft is good, for long term operation, the accident probability of pump is very few. The grease is used to lubricating the bearing,so it is convenient to maintain. Due to the adoption of the structure with back opening door, so the pipe needn't dismantling, the impeller and mechanical seal can be dismantled or replaced.Mechanical Seal and No leakage The mechanical seal is used for the gland seal of pump, so the consumption of power is very low, the seal is reliable and no leakage. The high quality seal can keep the pump to run more than 12000 hours. Light Weight, Less Occupying Land and Convenient Installation The most compact structure is adopted in the design of pump, so the weight of pump is light and the land occupied by pump is small. It is very convenient to move or install, especially it is suitable for the high building or the process flow.

Q:Pump pumping small is what happened?
Water pump pumping is small because of insufficient water source or pump head is not enough. At the outlet stop to measure the pressure, if there is a certain pressure, that is, the flow is too small, if there is no pressure, that is not enough head, or both small.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance parameters include flow, suction, lift, shaft power, water power, efficiency and so on.
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
22KW the water pump motor is 380V. 22KW rated current is about 44A, 10 square copper wire is enough, the motor will often start off ah, if it is not available for DZ108-63 50A, CJX2-50 50A contactor is 380V.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.The pump motor should be selected according to the selection of shaft power; motor shaft power power is greater than one level; for example: axle power is 15KW, select the motor should be: 18.5KW for motor with very few, according to the actual working conditions. 2 pole motor is generally used in the head of micro height, flow is not large (calculation is more complicated). Large flow, small lift occasions can choose 4 pole motor. Super large flow, lower head select 4 or 6 pole motor, when choose six pole motor, power can be reduced according to the shaft power of a grade.
Q:Does the IP55 indicate the lift on the water pump nameplate?
IP is INGRESS PROTECTION, that is, protection level,IP protection class is composed of two numbers, first numbers, from the lighting level to prevent intrusion of foreign objects, second numbers represent the tightness of anti moisture, waterproof lamp intrusion, the larger the number the higher the level of protection.Therefore, the pump IP refers to the pump with its own motor dust and waterproof level
Q:My fish tank pump is deep enough, it doesn't bubble up. Without oxygen supply, but it can filter. Does it damage the pump itself?
The easiest way is to pump a bottle of mineral water under the pump. It's too long to cut off some of it.Bottle to the end, the pump can beat oxygen on the line. A hole is under the bottle.
Q:What's the difference between a cold water pump and a hot water pump?
Cold water pump refers to the pump can be transported below 80 degrees C temperature liquid, known as cold water pump, between 80 degrees C to 120 degrees C, the temperature of the pump is called hot water pump.1, the characteristics of hot water pumpHot water pumps IRG hot water pump which is based on ISG and ISW centrifugal pump series on optimization designed, especially IRG type hot water circulating pump consumption, because the pump adopts a vertical motor is installed in the upper part, and a short frame between the pump and motor, not because of a mechanical seal Water Leakage phenomenon the motor inside the water inlet of the motor burn, but also in the IRG based on the design of the hot water pump mechanical seal in high temperature hot water pump maximum temperature by external tap water cooling device can reach 240 DEG C.2, the characteristics of cold water pumpSeal packing seal or mechanical seal rubber material Ding Qing cold water pump commonly used, the most common packing pump is IS single stage single suction centrifugal pump of the pump is also one of the earliest water pump products, because the filler itself requires liquid cooling and lubricating the pump temperature as the only 80 degrees, and packing seal cold water pump and dripping phenomenon has pollution to the pump body pump base and the surrounding environment, this kind of product has been ISG and ISW centrifugal pump series products replaced, ISG and ISW series of cold water with mechanical seal it has no water leakage phenomenon, and is directly connected with the impeller structure used in the the shaft of the motor, the noise and vibration above is obviously better than that of the old type of IS series cold water pump this kind of pump products commonly used in air conditioning water cycle with so called air conditioning chilled water circulating pump.
Q:What does diving pump 80JYWQ40-15-1600-4 stand for?
Because each manufacturer's label is different, the country although some specifications, but not enforced, so purely from the literal meaning is difficult to explainWe will try to solve the following problems:WQ-- sewage submersible pump80-- outlet diameter of water pump40 - M /h fand flow15 lift M1600 speed, r/min4Kw powerAs for J, Y is rated as sealed form and waterproof gradeI don't know whether it is correct or not
Q:What does water pump mean?
A device that applies power to a liquid and transfers it to where it is needed.
Q:How much is the flow rate of fire hydrant and spray shared water pump?
Fire fire water is superimposed, at the minimum, the lowest 5L/S automatic spraying fire hydrant, light danger level 13.9L/S, the least is 18.9L/S, but the data is useless, the data are not spraying fire hydrant, concrete analysis of high-rise buildings like the dangerous level according to the calculation, the general design, the concrete building needs the high-rise building minimum 20L/S, automatic spraying dangerous level according to the general 30L/S, 50L/S need to flow
Q:When the pump is connected in parallel, will the head and flow change?
2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume 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.
Q:Water pump mutual switching device
Now fire control cabinet has several requirements, multi-channel start, failure switch, automatic inspection, etc.Failure switching is when the main pump fails to start, the standby pump is put into operation automatically (and the two pumps are alternate).Mutual investment due to the original selection of different electrical principle is slightly different, but the same is the control of the main contactor, the main contactor when the main pump without electricity and suction time, time relay (or PLC fault detection delay is given by the pump start signal delay conversion) pump operation.You'd better find a fire drawing study.
