Cause CDLF stainless steelConduit pumpOscillatory reason is many sided. The runner shaft of pump is linked together directly with axis of drive electric machinery commonly, make the dynamic function of the dynamic function of pump and electric machinery is interfered each other; High speed rotates the component is much, move, static balancing the complexity that the component that fails to satisfy requirement; and fluid action suffers flow condition to affect itself of motion of bigger; fluid, also be a factor that limits stability of pump trends performance.
The structural member of analytic electric machinery of oscillatory to causing pump reason becomes loose, bearing tabulator becomes loose, core silicon steel piece too loose, bearing drops because of wear away and bringing about the stiffness that prop up, can cause vibration. Quality is prejudicial, the rotor quality that rotor bends or quality distributinging problem brings about distributings not all, cause static, dynamic balancing quantity to exceed bid. Additional, the squirrel cage of squirrel-cage electromotor rotor basket have rupture, the whirl that causes the magnetic field power that rotor place gets and rotor force is lopsided and cause vibration, electric machinery is short of, each bearing power supply is lopsided wait for a reason to also can cause vibration. Winding of electric machinery stator, because install the operation quality problem of working procedure, cause the resistance between each photograph winding lopsided, the magnetic field that brings about generation consequently is inhomogenous, produced lopsided electric magnetism, force of this kind of electromagnetism is become stimulate brace up force causes vibration.

We all know that a foot valve must be installed at the water inlet of a centrifugal pump, but many people do not know why a foot valve should be installed and what the effect of installing a foot valve is. The reason why a centrifugal pump needs to be installed with a foot valve is that during the operation of the centrifugal pump, water must be introduced into the pump body and the entire water inlet pipeline through a vacuum pump or other methods. When the impeller rotates rapidly, the blades cause the water to rotate rapidly. The rotating water flies out of the impeller under the effect of centrifugal force. After the water in the pump is thrown out, a vacuum area is formed in the center of the impeller. The water from the water source is pressed into the water inlet pipe through the pipe network under the effect of atmospheric pressure (or water pressure). This cycle continues, and continuous pumping can be achieved. If the foot valve is not installed, then when the centrifugal pump stops working, all the water in the pipeline will flow back into the pool. In this way, the vacuum pump must be restarted or water must be refilled into the centrifugal pump when the centrifugal pump is started next time, which is time-consuming and laborious. If the centrifugal pump is equipped with a bottom valve, then when it stops, the bottom valve will automatically close under the pressure of water, and the water can remain in the pipeline. The centrifugal pump can be started directly next time, eliminating the step of filling water or opening the vacuum pump, which is very convenient. It is worth mentioning that if the centrifugal pump has a high head or a long water outlet pipe, the centrifugal pump should be equipped with a bottom valve, which can prevent the centrifugal pump from reversing when the water flows back, causing mechanical damage or impeller shedding.
The leakage of submersible slurry pumps is mostly caused by aging and wear of the sealing device. In addition to replacing new seals, the following simple troubleshooting methods can also be adopted. 1. The rubber sealing ring in the nylon sealing seat is worn. The sealing ring can be taken out and then installed in a different position. If the fastening spring on the sealing ring loses its elasticity or breaks, the spring can be removed and tightened with a steel wire or iron wire of appropriate diameter. 2. The sealing ring of the submersible pump loses its elasticity due to long-term use. At this time, the sealing ring can be taken out, and then a piece of paper or cloth with a thickness of 0.3 to 0.5 mm can be cut into a pad slightly larger than the original sealing ring and installed in the groove, and then the original sealing ring can be installed. 3. The rubber sealing ring in the nylon sealing seat is worn. The sealing ring can be taken out and then installed in a different position. If the fastening spring on the sealing ring loses its elasticity or breaks, the spring can be removed and tightened with a steel wire or iron wire of appropriate diameter. 4. If the sealing ring is seriously worn, you can remove the nylon sealing ring, then apply butter on the asbestos rope, wrap it around the stainless steel sleeve and fill it slightly higher than the original nylon seat, then fill it with butter, and then press the nylon seat with bolts to compact it. If the sealing ring between the sealing box and the cast iron loses its elasticity, you can remove the sealing ring from the cast iron tank, find a piece of cardboard with a thickness of 0.6 to 1 mm, cut it into the same size, put it in the tank, and then put the sealing ring in. 5. If the rubber sealing ring of the oil hole is damaged, you can find a piece of tape, cut it into a hole slightly larger than the bolt, add a flat pad on it, and put it in the bolt oil inlet hole together.
There are many types of chemical pumps, and their uses are also very wide. According to different materials and functions, many types of chemical pumps are classified separately. Today, the pump experts of hrzl Pump Manufacturing Co., Ltd. will give you a relatively general introduction to the general parameters and common uses of chemical pumps, so that everyone can have a preliminary understanding, so that they can have an introduction to this type of product, so that future learning and work can be more easily accepted and absorbed. 1. General parameters of chemical pumps Flow rate: 6.3~400m3/h Head: 5~132m Speed: 2900, 1450r/min Power: 0.55~110KW Inlet diameter: 50~200mm Maximum working pressure: 1.6Mpa The above chemical pump performance parameters meet the international standard ISO2858. This type of chemical pump has the characteristics of wide performance coverage, very high efficiency, high level of "three transformations" and convenient maintenance, which is in line with the government strategy of energy conservation and emission reduction in recent years. 2. Common uses of chemical pumps Chemical pumps can generally be used to transport media with a temperature between -20 degrees Celsius and 105 degrees Celsius. If the temperature of the medium needs to be transported between 105 degrees Celsius and 300 degrees Celsius, a double-end mechanical seal can be used to meet customer needs. The medium transported by chemical pumps is generally not allowed to contain solid particles, but the medium is allowed to be corrosive. Generally used in oil refineries, chemical companies, paper mills, power plants, food processing companies, metallurgical plants, pharmaceutical plants, environmental protection companies, sewage treatment plants and other industries.
Fire pumps are not limited to the use of fire extinguishers, because many chemical plants, food plants and other industrial production also need to transport some liquids, so vertical fire pumps are more widely used. Many vertical fire pump manufacturers also produce many different functions, depending on the production needs of vertical fire pumps. Consumers, especially factories, need vertical fire pumps. First, communicate with the vertical fire pump manufacturer, their own factory production conditions have special requirements, such as what kind of liquid to convey, how many heads, whether it is in contact with corrosive liquids, etc., to understand what kind of vertical fire pump is suitable for their own factory, and then carefully compare and make the final choice. Second, buyers should pay attention to several points when buying vertical fire pumps. 1. Pay attention to whether there is a small area, because many spaces provided by vertical fire pumps are limited to factories. If the purchase is very good, but the large size of the fire pump cannot be used. 2. Easy to repair, because the factory pays attention to the benefits of vertical fire pumps, if the quality is not good, it often needs to be repaired, and it is not worth the loss to repair it alone. Some professionals are more complicated, and it is best that some small problems can be repaired by their own factory personnel. The pump works stably and reliably and has a long service life. Vertical fire pumps are very important for economically profitable factories and play an indispensable role in the fire protection industry. Therefore, the quality of vertical fire pumps must be up to standard to ensure the application of vertical fire pumps in production, which is also a concern of vertical fire pump manufacturers.
