Pump vibration produces noise solution

First, the pump vibration causes 1. Because the pump manufacturing process is not closed: the rotor is unbalanced; the pump and the motor shaft are not concentric; the rotor and the stator part collide or rub;
2. Due to the long use time, the pump wears and deteriorates: the impeller is loose; the bearing is damaged or the bearing clearance is large;
3. There are debris in the inlet pipe of the pump, the impeller, and the pump; the pump and the foundation are not fastened, and the resonance is enhanced;
4. When the water flow is propelled during the operation of the pump, the accompanying eddy current will inevitably generate vibration;
The vibration of the pump 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 general characteristics of the spring damper for the pump 1. The spring damper should have simple installation, sturdy and durable, good stability and beautiful appearance;
2. The pump installation site is often wet or directly exposed to the outside, which requires the spring damper to have good rust prevention capability. Generally, all ferrous materials are required to be galvanized or rust-proof, so as to ensure a long service life of the shock absorber. It is forbidden to use a spring damper that is simply painted or not rust-proof at all. Its life is too short, and there will be a lot of troubles when it is replaced.
3. The spring must meet the following requirements: the spring diameter should be not less than 0.8 times its 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 thus manufactured can ensure that the horizontal steel of the damper is sufficient so that the equipment is stable and not easy to fall, and the elasticity is durable, and the long-term vibration damping capability is ensured.
4. According to the weight of the pump, the spring compression capacity of the spring shock absorber should be greater than 20MM, and the rated compression of the shock absorber should not exceed the rated compression of the shock absorber, so as to ensure the best performance of the shock absorber. Vibration isolation effect.
5. Need to point out the problem, a kind of spring damper is popular in the market, it will completely hide the spring inside the outer casing, and it is very unreasonable to directly observe the state of the spring at the outside! Because, after using this type of damper for a period of time, if the spring is severely rusted, the manager can not find and replace it in time, and the spring may be broken, until the pump sinks and the pipeline has a terrible consequence. Try not to use such shock absorbers.
