Specifications
1,Single-stage single-suction
2,Axial suction centrifugal pump
3,Back-pull-out design
Min inlet pressure
Min inlet pressure depends on NPSH +0.5m safety margin + gasified pressure. It should be re-calculated the inlet pressure if one of the following happens.
*The liquid is more warm.
*The flow exceeds the nominate value.
*Suction distnace is very long or inlet pipe is very long.
*System pressure is too little.
*Inlet pressure is low.
Typical application
*Clean, thin, non-corrosive, non-flammable or non-explosive liquid without grain or fiber.
*Water supply system
*Heat, air condition system
*Irrigating, farming
*Booster, constant pressure water supply
*Industry cooling, heater circulation system
*Firefighting, splitting system
*Industry transferring, drainage system
Construction
*Non-self-priming, single stage, single suction, horizontal, axial suction and radical discharge, pump body is fixed by base.
*Use bering cradle, which can orientate bearing, prevent from radical vibration, improve the rigidity of rotary part.
*Compacted shaft, use deep grove grease lubricated roller bearing.
*Connect pump and motro with semi-flexible coupling.
*Use standard wearable mechanical seal.
*TEFC motor, size complies to IEC standard, installation type B3.
*The dimensions is conform to ISO 2858
Specificaton
*Flow: Max 520m3/h
*Power:Max 160Kw
*Head: Max 160m
*Liquid temperature: -15°C - 110°C
*Working pressure: Max 16bar
*Inlet and Outlet diameter: Inlet diameter: DN50-DN200; Outlet diameter: DN32-DN150
Curve conditions
*Curves tolerance is according to ISO9906, Annex A;
*All curves are based on the measured value of constant motor speed 2900rpm, 2950rpm, 1450rpm or 1480rpm.
*The measurements were made with airless water at temperature of 20°C. The curves apply to a kinematic vis-cosity of 1 mm2/s (1 cst)
Features
*Back-pull-out design, without having to disurb pump body and pipelines when servicing.
*All the models only use 4 kinds of pump shafts and bearing cover, make parts exchangeable.
*Impeller is optimum design, inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiently, which makes pump work stable with little noise.
*Casing and casing cover use wearing neck ring structure, which makes pump easy to maintain, makes parts work longer. The replaceable seal ring, makes pump work efficiently in a long time.
- Q: Fire hydrant pump button, under what circumstances do not need to install?
- There are four things to do:Fire hydrant button to meet the requirements of national standards.In addition to pumping, it can show the location of fire.
- Q: You'd better point out the details.... There are 2 best ways of experience and formulaCan you say a simple point, such as multi-stage pump, when the pump is higher than the motor, 30 wire is the next mouth how to do?
- Looking forAlignment means the position of the center of rotation of the pump and motor so that they are in the same line.At least three times after the initial installation or after installation:
- Q: What are the important parameters of the pump?
- Mass flow is expressed in Qm units: t/h, kg/s, etc.The relation between mass flow and volume flow is:Qm= P QIn the p - type liquid density (kg/m3, t/m3), room temperature water P =1000kg/m3.Lift H
- Q: What is the pump delivery? What's the difference between years and years?
- Secondly, the landlord asked the question, although I did not go to the insurance company to practice the operation, but to my four years of learning, as well as internship experience, or can help you analyze, and I hope to help you.Pay is a one-time payment of premium -- all wholesale D sea n
- Q: Rules for operation of centrifugal pumps
- Operating rules:1, before starting to check whether the water pump foot loose, coupling shield, and motor fan blade cover is intact, in order to ensure the safety of equipment and personal safety.2. Check whether the inlet valve is open and open as fully as possible. Is the outlet valve closed, open the bleeder valve, exhaust until there is no air, and close the bleeder valve. At the end of the valve to the pipeline in the pump cavity filled with water.
- Q: What is the function of the heating pump system for the water pump design?
- As the feed water temperature is higher, in the case of non warm pump start, will make the pump body is subject to greater thermal impact; in addition, the flow components with the pump contact heating fast, not contact with water directly heating slowly. This expansion due to uneven speed, it will inevitably produce thermal stress, deformation of the pump body, sealing surface, the joint surface is lax and leaking phenomenon. Therefore, the warm water pump system is designed for the water pump.
- Q: Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
- What is straight pump and non direct pump? Direct coupled pump shaft and the motor shaft is directly coupled with the coupling and non direct coupled pump: pump shaft and motor shaft through the belt pulley, V-belt connection or other forms of transmission. What is the difference in the structure: the direct coupled pump has the advantages of compact structure, simple installation, but the relatively small power; non direct coupled pump: pump and motor is independent, the two transfer torque through the belt, the structure is relatively large, complex installation, general power is relatively large.
- 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 do you mean by the self coupling device on the pump?
- Installation of GAK self coupling device:The installation of automatic coupling submersible sewage pump is mainly the installation of coupling device and the lifting of pump. In the pump before the installation of the rings on the chain, and the pump used for lifting.Installation procedure of coupling device:The coupling frame with four bolts fixed on the pump body; the water outlet pipe is fixed on the substrate; positioning cone mounted on the pipe seat; the lower end of the guide pipe is sleeved in the positioning cone, the upper end is sheathed on the guide rod of the rubber block; the guide rod frame is fixed on the pool wall. The function of the rubber block: the axial compression degree of the rubber block is adjusted by the screw on the guide rod frame, so that the diameter of the rubber block is consistent with the inner diameter of the guide rod, and the guide rod is stable.
- Q: How long does the fine stone pump need maintenance? What should I pay attention to?
- Daily maintenance of concrete pump, that is, routine maintenance in use, including inspection, cleaning, lubrication, fastening, adjustment, leak hunting, supplement of hydraulic oil, etc.. 8.1 hydraulic components inspection, due to the complexity of the equipment, we recommend practical experts to carry out the inspection of hydraulic system. If a fault is found, check the cause and repair the entire loop before proceeding to any operation. - found that oil has diarrhea, excluding leakage reasons. - inspect safety valves, hydraulic systems, steel tubes and hoses, fittings, cylinders, and find any wear and tear (pipe explosion may cause very serious consequences)
