The vibration of centrifugal pump can be analyzed from four reasons
The pump body of Centrifugal pump often happens vibration at working and vibration will result in a centrifugal pump can't work normally, affect the use of the user, and even bring some economic loss to the customer.Therefore, the vibration of centrifugal pump has been one of the important topics that have puzzled users.The four main causes of centrifugal pump vibration are analyzed by the pump valve technology.
1. Product design and quality
Because of the current market turmoil, the cost of setting up a company is low, leading to a large number of empty shell companies that have not been produced, and the market for small businesses that are not up to the standard.There is no guarantee of the quality and technology of some products.Will appear such as motor and pump moving parts mass unbalance, churning out, installation quality bad, asymmetric unit axis, the pendulum degrees more than permitted, parts of mechanical strength and stiffness were some quality problems, can all result in a centrifugal pump products is not stable, causing centrifugal pump vibration at work happens.So customers must choose regular manufacturers when choosing.
2. Motor
On the product structure of centrifugal pump, the motor unit is indispensable parts, if the motor internal magnetic imbalance and other disorders of the electric system, it is likely to lead to the entire unit vibration and noise.If the asynchronous motor is in operation, the radial alternating magnetic pull of the rotor is generated by the interaction of the fixed rotor tooth harmonic flux.And at work, such as large-scale synchronous motor stator magnetic center inconsistent or air gap difference exceeds allowable deviation value in all directions, etc., can cause motor periodic vibration and noises.Therefore, the selection and quality of the motor also affect the vibration of the centrifugal pump.
3. Hydraulic aspects
The work of centrifugal pump is closely related to water and other media, so the transmission of natural medium can also affect the work of centrifugal pump.Such as uneven distribution of water pump inlet flow rate and pressure, pump import and export work the pressure fluctuation of the liquid, liquid flow, bias current and flow, the working condition of quota and water pump cavitation, etc., due to a variety of causes will lead to centrifugal pump vibration at work.
4. Normal mechanical wear of the product itself
Products in the product after a long work, wear parts, lead to the normal operation of the centrifugal pump of pump and work, vibration happens frequently, then you need inspection on centrifugal pump, for parts damage caused by product failure.
The centrifugal pump vibration, first of all must stop work, carefully check the cause of the failure, in accordance with the actual situation maintenance treatment.If there are no professionals, please contact the manufacturer to provide technical support.
