multistage centrifugal pump hydraulic structure parameters is to get the highest efficiency of the optimal combination of multi-stage centrifugal pump is our good pump type in abroad on the basis of combining the use of user requirements and fire related standards, and according to JB/TQ6435 - 92 standard design and manufacture of a new generation of products. Multistage centrifugal pump suction and discharge in a straight line. By of rotor shaft, impeller, the impeller block set, shaft sleeve and other parts, water, middle, water paragraphs with tighten bolt connection. Shaft sealing adopts mechanical seal, with the balance chamber pressure lubrication and cooling water. Multistage centrifugal pump is the major industry of hot and cold water or liquids such as physical and chemical properties similar to water is the best pump for the transmission. This department multistage centrifugal pump products all adopt the computer design and optimization of processing, the company has the abundant technical force, rich production experience and perfect detection means, thus ensuring product quality is stable and reliable. Multistage centrifugal pump product features: 1, advanced hydraulic model, high efficiency and wide performance range. 2, easy installation, maintenance, pipeline installation, import and export can like valves installed in any position and any direction, multistage centrifugal pump installation and maintenance is very convenient. 3, multi-stage centrifugal pump, beautiful shape, made of high quality stainless steel jacket, beautiful appearance. 4, less operation, and maintenance cost, high quality mechanical seal, wear resistance, no leakage and long service life, low failure rate, the operation of the multi-stage centrifugal pump with less maintenance cost. 5, unique parts, reduce noise: unique design of the hydraulic components performance of flow, the flow most the earth to reduce noise. 6, vertical structure, cover an area of an area small. Multistage centrifugal pump motor and pump together as a whole, motor rotor fulcrum bearing and water pump bearing, make the pump impeller rotating power transfer to a rigid work pressure reducing valve. Multistage centrifugal pump impeller with eddy shell is only 0. 10 - 0. 22 mm clearance, sundry sand easily jammed the impeller, the motor rotor to rotate and failure. From repair multistage centrifugal water pump failure analysis for impeller jammed damage probability accounted for more than eighty percent. When turn off the power switch, such as found that the motor does not turn, should turn off the power supply in time, when the motor work with inductance to produce a rotating magnetic field, a short time, the motor will not damage. Can use the screwdriver to remove the motor back cover, with the hand around rotating fan Ye Zhi to flexible back to back cover again electrify. Multistage centrifugal pump before use should pay attention to voltage is consistent and safe use of electricity, because of the fresh water pump is working in humid environment, the power switch before should be fitted with a leakage protection switch. Multistage centrifugal pump work, don't move, the bottom of the suction valve 0 vertically into the water. When 4 meters, water quality is poorer, should set filter, prevent sundry into a multistage centrifugal pump affect the pump running. Multistage centrifugal pump of hydraulic structure parameters is to obtain the best combination of highest efficiency. For other pumps, pump of this kind of special requirement its efficiency can not be more than the same period of the fresh water pump efficiency. The other is the main reason of the pump efficiency is lower than the fresh water pump their circulation road widening. Efficiency decline in the value of the main related to widen the extent of the. Other pump flow channel widening is to prevent blocking. Multistage centrifugal pump for conveying water or physical and chemical properties similar to water other liquid, the temperature is not higher than 80 ℃. Applicable to industrial and urban water supply, water drainage, can also be used for agricultural irrigation and drainage. The pump design to choose domestic excellent hydraulic model, the multistage centrifugal pump adopts IS type of centrifugal pump performance parameters, on the basis of the general vertical pump to design ingenious combination and become, at the same time according to different use, such as temperature, medium based on ALG type derived for hot water, high temperature corrosion resistant chemical pump, oil pump. Multistage centrifugal pump has the advantages of high efficiency and energy saving, low noise, reliable performance, multi-stage centrifugal pump in accordance with the latest national machinery JB/T53058 - 93 standard requirements, multi-stage centrifugal pump product design and manufacture according to the international standard ISO2858 being adopted. Can transport water and physical and chemical properties similar to other liquid Yu Qingshui, multistage centrifugal pump is applicable to industrial and urban water supply and drainage, pressurized water supply in high-rise building, garden sprinkler irrigation, fire pressurization, long-distance transmission, hvac refrigeration cycle, cold and hot water circulation pressurization in the bathroom, etc, and form a complete set of equipment, using temperature T < 80 ℃. Multistage centrifugal pump is will rust, but not necessarily the rust of the fresh water pump, water pressure small pipe scale, rust easily washed out after charging. Water pump about 100 watts of power should be enough, but what matters is head, if you don't have enough floor high lift water will not come on. Pay attention to when buy, best buy with self-control, as long as the faucets pump will automatically open, shut down automatically stop, use very convenient. For reference only. Multistage centrifugal pump in the case of long time didn't use the water corrosion water pump body, a reserved turbid water in water tank 0 ~ ~ ~ but over a period of time. Tap water didn't work for a long time also can appear a rusty water in the home, the pump should be 370 w, you noise because of the water pump bearing need to refuel, replacement. The 90 w and 120 w pipeline booster pump can also be used actually, can use 120 w household solar energy water heater of the booster pump. And multistage centrifugal pump suction side is made of brass, and water will not rust.
