How to deal with the noise caused by the vibration of the water pump
First, the pump vibration causes 1. Due to the pump manufacturing process, but off: the rotor is not balanced; the pump and the motor shaft are not the same; the rotor and the stator part of the collision or friction;
2. Due to a long use time, the water pump wears out: the impeller is loose; the bearing is damaged or the bearing clearance is large;
3. There are impurities in the inlet pipe of the pump, in the impeller, and in the pump; the water pump and the foundation are not fixed tightly, and the resonance enhances the image;
4. When the water pump is advancing the water flow during operation, accompanied by turbulence, cavitation will inevitably produce vibration;
Water pump vibrations will inevitably produce vibration and noise! Therefore, to solve the problem of pump noise, the pump vibration should be solved first. The following describes the spring damper for the pump.
Second, the spring damper for the pump should have the general characteristics of 1. The spring damper should have a simple installation, strong and durable, good stability, beautiful appearance;
2. Water pump installation sites are often wet or directly exposed to the outside, which requires spring shock absorbers to have good anti-rust capabilities. General requirements All ferrous materials need to use galvanized rust treatment or ED paint rust treatment, so as to ensure the longer life of the shock absorber. Do not use spring shock absorbers that are simply painted or not treated at all, and their life is too short. There will be a lot of trouble when they are replaced.
3. The spring must meet the following requirements: The spring diameter should not be less than 0.8 times the height under the rated load; The spring must have a certain extra stroke, at least equal to 50% of the rated static deflection; The number of spring coils should not be too small, generally Not less than 6 laps; the spring made in this way can ensure that the damper has sufficient horizontal rigidity so that the equipment is stable and less prone to toppling, the elasticity is long-lasting, and the durability of vibration is ensured.
4. According to the reasonable selection of the weight of the water pump, the spring compression of the spring shock absorber bearing the weight of the water pump should be greater than 20 MM, not exceeding the shock absorber's rated compression amount, so as to ensure the best performance of the shock absorber. Vibration isolation effect.
5. Need to point out that there is a class of spring shock absorbers that are popular in the market. It hides springs completely inside the casing. It is very unreasonable to observe the state of the springs directly outside. Therefore, if such a damper is used for a period of time, if there is a serious rust in the spring, the manager can not find it and replace it in time. The spring may break, the water pump may sink, and the terrible consequences of breaking the pipeline may occur. Should try not to use such shock absorbers.
