The installation of self
priming pumps, especially newly installed pumps, must take vibration isolation
measures and avoid laziness, otherwise significant vibration and noise may occur
during use. When running a self priming pump, the noise is loud, which can
damage the equipment and also cause noise pollution. Therefore, it is necessary
to do a good job of vibration isolation. How can self priming pumps achieve
effective vibration isolation?
1、 The vibration isolation components should
be symmetrically arranged along the central axis of the self priming pump unit.
The plane layout of rubber vibration isolation pads can be arranged in a
clockwise or counterclockwise direction.
2、 When the vibration isolation
components of the unit adopt six support points, four of them should be arranged
at the four corners of the inert block or steel frame, and the other two should
be set on the long side line and adjusted in position to ensure that the
compression deformation of the vibration isolation components is as consistent
as possible.
3、 When installing rubber isolation pads or damping spring
isolators for vibration isolation of self priming pump units, generally, there
is no need to bond or fix the rubber isolation pads and damping spring isolators
to the ground, as well as to the inert block or steel frame.
4、 When rubber
isolators are used for vibration isolation installation of unsealed self priming
pump units, a steel frame should be installed under the base of the water pump
unit and anchored installation should be adopted; The steel frame and rubber
isolator should be fixed with bolts. Install anchor bolts in the ground or
floor, and the rubber vibration isolator is fixed to the ground or floor through
the anchor bolts.
5、 The edge line of the rubber isolation pad shall not
exceed the edge line of the inert block; The supporting area of the steel frame
should not be less than the supporting area of the top of the vibration
isolation element.
6、 The rubber isolation pad is arranged in a single layer,
and when the frequency ratio cannot meet the requirements, it can be arranged in
multiple layers in series, but the number of isolation pad layers should not
exceed five.
7、 When the rubber vibration isolation pad is set in multiple
layers in series, each layer of vibration isolation pad is separated by a
galvanized steel plate with a thickness of not less than 4mm. The steel plate
should be flat, and the vibration isolation pad and steel plate should be bonded
with adhesive. The flat size of the galvanized steel plate should be 10mm larger
than each end of the rubber vibration isolation pad. The rubber vibration
isolation pads bonded to the upper and lower layers of galvanized steel plates
should be staggered.
8、 Before installing the ZXP stainless steel self
priming pump during construction, it should be checked in a timely manner.
During installation, the static compression deformation of the isolation element
should not exceed the allowable value. Moreover, the vibration isolation
components of the unit should avoid contact with substances such as acids,
alkalis, and organic solvents.
Attention should be paid to these aspects in
the design, manufacturing, and maintenance of self priming pumps. Only by
following the requirements can vibration and noise be reduced, and equipment
damage be reduced. If it cannot be resolved, you can consult us.
