transfer pump

If the pump produces abnormal vibration, this vibration will directly affect the safe operation of the pump. When the vibration is serious, some parts will be deformed or even in danger of breaking, which will seriously affect the service life of the pump.

At the same time, due to vibration, the bolts of the rotating parts of the water pump will gradually loosen, which may cause the mechanical parts to be thrown out and hurt the safety of the staff. The vibration of the water pump will also generate noise, which will seriously affect the working environment. From the perspective of water pump installation, we control the vibration of the water pump, and can achieve a vibration isolation effect of more than 85-99% by the following methods, thereby fundamentally solving the problems that the vibration of the water pump brings to people's lives and industrial production.

1. Control and management of water pump vibration: 1. Install spring vibration isolator: a. Selection of water pump spring vibration isolator: Generally, a self-supporting spring vibration damper is used, which has the advantages of simple structure and low cost; the spring is exposed, It is ouke pump convenient to observe the state of the spring at any time, and deal with the spring to be replaced in advance to avoid excessive corrosion of the spring, which will cause the sudden settlement of the water pump and cause equipment damage and pipeline breakage.

b. Selection of springs: Generally, shock absorber manufacturers must meet the following requirements when choosing springs: the diameter of the spring should not be less than 0.8 times its height under rated load; the spring must have a certain extra stroke, and the vortex flowmeter should be at least equal to the rated static 50% of the deflection; the horizontal stiffness of the spring is at least 100% of the straight stiffness to ensure the stability of the shock absorber. c. Selection of the deflection of the spring shock absorber; usually the rated deflection of the spring shock absorber (rated spring compression amount) proposed by the shock absorber manufacturer is generally 25MM (the self-frequency value is about 3-4HZ), and this deflection can be 650 Vibration isolation of the pump at rpm.

When the rotation speed is lower than 650, it is recommended to use a spring isolator with a deflection below 40. 2. Installation of rubber vibration isolators: the choice of rubber vibration isolators: the material is generally neoprene (C.R), natural rubber (N.R); compression type rubber vibration dampers are generally used, and for lighter weight pumps, optional Shear type rubber shock absorber; Compared with the spring shock absorber, the vibration isolation performance of the rubber shock absorber is relatively different. 3. Installing an inert base: In order to meet more stringent vibration control standards, when installing an inert base, it is undoubtedly the best choice to use a spring vibration isolator.

Specifications of the inert base: the weight of the base is about 1-2 times the weight of the water pump; the frame is made of grooved iron, and its height is not less than 1/12 of the length, but not less than 150MM and not higher than 300MM; The width should be able to cover the entire water pump, and it is appropriate to leave 10-15 cm on each side. And it is best to cover the bay head; pour cement inside, and build a layer of steel mesh at one-third of the height; install spring vibration isolators to set the distance between the base and the foundation to 3-5 cm.
