ISW series horizontal pipeline centrifugal pump


Product Description



1, smooth operation: absolute concentricity of pump shaft excellent static and dynamic balance of impeller ensure stable operation, no vibration.
2, watertight: hard alloy seal with different materials to ensure the transportation of different media are no leakage.
3, low noise: two low noise bearing of the water pump, smooth operation, in addition to the motor faint sound, the basic no noise.
4, low failure rate, structure is simple and reasonable, the key part adopts the international first-class quality form a complete set, the trouble-free working time greatly improve.
5, easy maintenance: replace seal and bearing, simple convenient.
6, more space-effective: the outlet is available to the left, right, up three direction, easy for pipeline layout and installation, save a space.
7, ISW horizontal fresh water pump for conveying water and physical and chemical properties of YuQingShui similar other liquid and suitable for industrial and urban water supply, pressurized water supply in high-rise constructions, garden sprinkler irrigation, fire booster, distant distance transportation, hvac refrigeration cycle, such as the bathroom, cold and hot water circulation pressurization and equipment accessories, using temperature T acuities were 80 °C.
8, ISWR horizontal hot water pump are widely used in metallurgy, chemical industry, textile, papermaking, and hotels etc boiler hot water booster cycle transport and urban heating system, ISWR type using temperature T 120 °C or less.
9, ISWH horizontal chemical pump, for delivery not containing solid particles, and viscosity similar to corrosive liquid water, used in petroleum, chemical, metallurgy, electric power, papermaking, food, pharmacy and synthetic fibre and other departments, the use of temperature from °C ~ + 120 °C.
10, ISWB horizontal pipeline oil pump for transport gasoline, kerosene, diesel oil and other oil products or flammable, late detonation liquid, by conveying medium temperature of 20 °C ~ + - 120 °C

Q:What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?
Mechanical efficiency: the ratio of theoretical torque to actual torque of the pump.
Q:What is the series of pumps? What's the difference between a unipolar and a multistage?
Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
Q:Concrete pump 125 pipe wall thickness
Concrete pump diameter 125mm, pipe wall thickness is generally 4mm, also have 4.25mm, 4.5mm, 4.75mm, need to be in accordance with the rules of transport.
Q:How is the pump level of submersible sewage pump determined?
Below the top elevation of the sump, 200 is the warning water levelBut note: 1, the effective volume of the sump meets the requirements. 2, the pump should have enough submerged water level
Q:What are the application areas of pumps?
Water pump has different uses, different transmission liquid medium, different flow, lift range, therefore, its structure form is not the same, the material is also different, summed up, can be roughly divided into:
Q:How accurate is the metering pump?
Three automatic compensation valve device widely used in diaphragm metering pump, especially with suction height requirements, can only be used by three separate Fujian (safety valve, discharge valve and oil supply valve) compensation device.
Q:Any center of the pump
Alignment methods and requirements:1, check two feeler dial gauge or flange coupling the parallelism, usually with clearance between the both ends of the side instead of difference, in the circumferential direction every 900 measure, the maximum and minimum gap gap difference (Ab) less than or equal to 0.3 mm.2, the coupling flanges outside the park up and down, left and right four position to check whether they are in the same line, C less than or equal to 0.1 mm.When looking for a positive C, it will affect (a - b), finding the right (a - b) will affect the C, to balance each other. It's easier for an unskilled comrade to find C (a - b) first, and then find a positive one. Through the adjustment of the motor at the foot of the gasket thickness (Ab) and meet the requirements of C.Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition.It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
Q:5 floor water pressure is too low, what kind of water pump is better?
Pipe blockage, leaks, or throttling devices are not opened. This can be tested on a pipe with a pressure gauge;Water pump is equipped with power source, power or speed does not match, check the pump and power end nameplate, power end of the pump power is generally 1.1.5 times;
Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system?
Pump control system is generally used for closed systems, the flow of the oil pump changes to control the motor or cylinder actuator action. The utility model has the advantages that the principle is simple, and the power of the engine can be fully utilized. The disadvantage is that the calorific value of larger, relatively poor precision.
Q:What is the Rhodes pump?
The ultimate vacuum of roots pump depends on the pump structure and manufacturing accuracy, and also depends on the limit vacuum of the front pump. In order to increase the limit vacuum of the pump, the roots pump can be used in series. The working principle of roots pump is similar to roots blower. As the rotor continues to rotate, the gas is pumped from the intake air to the space between the rotor and the pump housing V0, and then discharged through the exhaust port. Since the V0 space is fully enclosed after inhalation, the gas in the pump cavity does not compress and expand. But when the top of the rotor turns off the edge of the exhaust and the V0 space communicates with the exhaust side, the gas pressure at the exhaust side is higher, and a part of the gas flows back into the space V0, causing a sudden increase in the gas pressure. As the rotor continues to rotate, the gas is expelled from the pump. Roots pump in the pump cavity, there are two "8" shape of the rotor perpendicular to each other on a pair of parallel axis, by a transmission ratio of 1 of a pair of gear belt movements synchronous reverse movement of each other. In the rotor, the rotor and the pump housing between the wall to maintain a certain gap, you can achieve high speed operation.
