Causes of Horizontal Pump Vibration
1. The manufacturing process of the water pump is not up to standard: the rotor is unbalanced; The pump and motor shafts are not concentric; Collision or friction between rotor and stator;
2. Due to long service time, the water pump is worn and aged: the impeller is loose; Bearing damage or large bearing clearance;
3. There are sundries in the water pump inlet pipe, impeller and pump; The water pump is not fixed firmly with the foundation, and resonance strengthening phenomenon occurs;
4. When the water pump is working to promote the water flow, the accompanying vortex and cavitation will inevitably produce vibration; Water pump is a machine for conveying fluid or pressurizing it, including some machines for conveying gas. Its function is to supply cooling water to the steam turbine condenser to cool the exhaust steam of the condenser. Generally, it can be divided into vertical and horizontal type. It can operate circularly depending on the impact of water flow. To prevent resonance, ZTA floor damping butterfly valve damper must be used.
1. ZTA landing damping butterfly valve damper structure. Point:
ZTA floor damping butterfly valve damper is a new electric butterfly valve product composed of butterfly valve and its combination. The butterfly valve in this electric butterfly valve can play a role in vibration reduction as well as sound insulation. The butterfly valve is protected inside the product, and the butterfly valve avoids oxidation, so that the service life of the butterfly valve damper is longer.
2. Design principle of ZTA floor damping butterfly valve damper:
ZTA floor damping butterfly valve shock absorber is designed according to the principle of "low frequency and large damping shock absorber", and multiple compression screw butterfly valve combinations are used in parallel to improve the stability of the product. Using metal wire mesh as damping material can not only increase the damping coefficient, overcome the resonance phenomenon that is easy to occur when its damping ratio is small, but also extend the service life. In order to facilitate installation, the upper and lower end faces of the shock absorber are sleeved with gaskets to increase the friction coefficient, which can be directly placed between the vibration isolation pedestal and the supporting structure, and generally do not need to be connected and fixed.
Urban construction tends to be high-level, and people's domestic water needs to be boosted. As an important equipment for pressure lifting, water pumps are used more and more widely. However, the problems of noise and vibration caused by it also put forward how to control and protect environmental workers.
