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 are the ways of hydraulic pumps?
There are several ways:Direct flow mode, such as external gear pump;Port plate, such as vane pump, axial piston pump, etc.;
Q:What is the pumping property of concrete?
Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement
Q:Is the diaphragm pump and the drain pump one?
Generally composed of actuators and valves.Pneumatic diaphragm pump, which has four kinds of materials: plastic, aluminum alloy, cast iron, stainless steel. The electric diaphragm pump has four kinds of materials: plastic, aluminum alloy, cast iron and stainless steel. Diaphragm pump diaphragm according to different liquid media, respectively, NBR, chloroprene rubber, fluorine rubber, PTFE, poly 46 ethylene to meet the needs. Placed in a variety of special occasions, for pumping various media.
Q:What are the general water pump failure, how to repair?
Two, pump speed is low(1) human factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.(2) the mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or deformation of the pump shaft bending, resulting in multi impeller, directly with the pump body friction, or bearing damage, are likely to reduce the pump speed.(3) the maintenance of the power machine is not working. The motor is lost because of winding burn, the change of winding number, wire diameter, wiring method, or failure in maintenance can not change the pump speed.
Q:What is the difference between centrifugal pump and self suction pump? Which is better?
Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. The centrifugal pump drives the water to rotate through the high speed rotating impeller blade, and the water is thrown out so as to achieve the purpose of pumping water. The impeller rotates at high speed, forcing the liquid at the center of the impeller to be removed at high speeds, resulting in a low pressure at the center of the impeller, and the liquid in the lower trough is continuously sucked.
Q:Why does the centrifugal pump close the pressure to start?
The motor power is selected according to the rated flow of shaft power points plus 15 to 25%, if the outlet valve is fully open to start, the pump flow may deviate from the amount of fixed lot, pump efficiency also reduces a lot, resulting in shaft power greater than the motor power caused by tripping even burned electric machine.
Q:The difference between diaphragm pumps, vacuum pumps and centrifugal pumps
The diaphragm pump and centrifugal pump refer to the structure of the pump, and the vacuum pump means the use of the pump. There is no comparability between them.Centrifugal is the sign of inertia of an object. As the umbrella turns, water droplets move out of the outer edge of the umbrella and are thrown out. This is what is called centrifugal. Centrifugal pump is designed according to this principle. The high speed rotating impeller blade drives the medium to rotate and is thrown out so as to achieve the purpose of conveying.
Q:What is the lift of diaphragm pump?
Diaphragm pump lift is different from the centrifugal pump, refers to the diaphragm pump can raise the height of water, the unit is meters water column. Lift depends on the size of the outlet pressure, the pressure per kilogram is equivalent to 10 meters height
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:Brief description of centrifugal pump on / off operation
Two, centrifugal pump start(1) the pump entrance valve fully open, start motor, outlet valve fully closed, fully check operation of pump.(2) when the pump outlet pressure is higher than the operation pressure, the outlet valve is gradually opened to control the flow and pressure of the pump.(3) check whether the motor current is within the rated value, such as the pump in the rated flow operation, and the motor overload should stop the pump inspection.
