ISG series vertical pipeline cooling water centrifugal pump

    ISG series single stage single suction pipeline centrifugal pump is designed on the base of

    domestic execellent water power model and the performance parameter of  IS series cen-

    trifugal pump.

    ISG Series centrifugal pumps are designed for such as hot water pump and corrosion resi-

    stance pump and oil pump for  the different temperatures and liquids. The pump has good

    performance of reliable operation and high effeciency and little noise etc.

ISG series vertical pipeline cooling water centrifugal pump

  1,Compact structure,horizontal structure ,beautiful appearance and less area of occupied land,

      which comparing with the ordinary ones is reduced by 30%;

  2,Stable running ,low noise,high concentricity of assembly.By the straight joint between motor

     and the pump.the moddle structure is made simplified ,thus enhancing the running  stability ,

     making the impeller of a good balance of moving -resting ,resulting in no vibration during run-

     ning and improving the environment of usage .

  3, No leakage .a mechanical seal of antisepticcaarbide alloy is ued for the shaft sealing so as to

     let rid of the serious leakage of the fillings of centrifugal pumps and ensure the operating place  

     clean and neat ,

 4,Convenient service .


ISG series vertical pipeline cooling water centrifugal pump

 1.ISG series vertical pipeline centrifugal pump is used to transport the water and other liquid

     similar to the water in physical and chemical characteristic. It is widely used for the drainage

     in industry and city, booster and water supply for high-building, irrigation in garden, booster

     in fire fighting, transporting from along distance, water circulation in circultion system etc.

     Working Temperature<80oC.

 2. IRG series vertical hot water pump is suitable in metallurgy, chemical industry, textile, timber

     processing, paper making and booster and circulating for high temperature and hot water in

     hotel.

     Working temperature <240C.

 3. IHG series vertical pipeline chemical pump transports the liquid which is corrosive an without

     solidgrain and similar to water in viscosity. It is suitable in petroleum, chemical industry,metal-

     lurgy, electric power, paper making, food an   pharmacy and synthetic fibre etc.

 4. IHG series stainless steel chemicalcentrifugal pump with explosion-proof is suitable to trans-

     port the flammable  chemical liquid.


Q:What are the main performance parameters of the pump?
The amount of liquid supplied by a pump in unit time. Volume flow Q, unit m3 / s. There is mass flow G, unit is kg / s.
Q:Working principle and structure of external gear pump
The principle of the gear pump, gear pump structure consists of two gear mesh together with each other, and composed of pumps known as gear pumps. It relies on the gear teeth meshing space change in volume to transport the liquid, it belongs to the rotary pump, also can be considered as a volume pump. There are many kinds of gear pumps. According to the meshing mode, it can be divided into external gear pump and internal gear pump. According to the tooth shape of gear, it can be divided into positive gear pump, helical gear pump and herringbone gear pump.
Q:Rules for operation of centrifugal pumps
5, before you stop, you should gradually close the outlet valve, then turn off the power supply.6, with the check valve line, in ensuring the check valve intact, without closing the outlet valve, check the pump cavity, no air can be directly switched on.
Q:Why can't the centrifugal pump pump the vacuum?
Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.
Q:The distance from the pump button to the ground
After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.
Q:What are the characteristics of a pipe shield pump?
Four, high melting point in the pump hydraulic side and the motor side with a jacket, the jacket can be steam or a certain temperature of liquid to prevent high melting liquid crystallization. The outer circulation pipe of the pump should also be insulated (heating) jacket. Five, high pressure shielding pump shell is a high pressure container, so that the pump can withstand high system pressure. In order to support the shield under internal high pressure, the stator coil itself can be used to bear the pressure. Can also be made in high temperature and high pressure under the operation of the canned pump. Six, since the suction port of the pump impeller center is much higher than that in stopping the pump, when inhaled NO liquid in the tube, the impeller and the increase of the pump chamber is filled with liquid, and then start without irrigation, the pump can work. Self-priming pumps are especially suited for extracting liquids from underground containers. In addition, according to different methods can be divided into liquid type, mud type, high pressure pipeline type, as well as for ships, nuclear power plants and absorption refrigeration devices for various types of canned pumps. Can also be divided into vertical, horizontal, online and single-stage, multi-level and other different types.
Q:Please give me professionals to calculate, the cylinder bore is 100 and the rate of 20m/s, the leakage can be ignored, but to the large flow pump!
2. displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.
Q:How to select metering pump head?
When it comes to metering pump heads, the usual problem is when they measure acid, chlorine, fluoride, and hydrogen peroxide. Due to the difference in concentration and operating temperature, it is difficult to determine the specific pump head material.
Q:How to adjust the flow of piston pump?
The oil pan with oil liquid through the suction port and the piston cylinder; from 180 degrees to 360 degrees, the piston cylinder volume decreases, so the oil liquid in the pan with oil discharged from the outlet of the liquid. The pump works continuously as long as the drive shaft rotates.
Q:What is the pumping property of concrete?
Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.
