Abstract
A centrifugal pump belongs to the technical field of delivery pumps. The centrifugal pump comprises a motor and a pump body, wherein the motor and the pump body are fixed on a mounting platform, four corners of the mounting platform are connected to shock absorption feet in an adjustable mode through screws, the shock absorption feet are made of buffer materials and located at the bottom of the mounting platform, fixing holes are formed in two sides of the shock absorption feet, a locking nut is arranged at the top of the mounting platform and is in threaded connection with the screws. Centrifugal pump, this centrifugal pump are when the operation produces the vibration, and the vibration passes through the screw rod and conducts to the shock attenuation lower margin, because the shock attenuation lower margin adopts buffer material to make, can produce the deformation of small amplitude and offset the damage that vibrations caused to material rigid connection, extension equipment life also can have the noise that effectual reduction produced from this simultaneously.
Description
Technical Field
The utility model belongs to the technical field of the delivery pump, especially, relate to a centrifugal pump.
Background
The centrifugal pump is a pump which utilizes centrifugal force generated when an impeller rotates to convey liquid, when the centrifugal pump works, the impeller is driven by a pump shaft to rotate at high speed with the conveyed liquid, the liquid is thrown to the outer edge of the impeller and enters a conveying pipeline through a flow channel of a volute pump shell and a liquid outlet of the pump. However, when the power of the motor is increased, the housing may be vibrated, which may affect the service life of the pump, and noise may be generated.
Disclosure of Invention
To the problem that prior art exists, the utility model provides a centrifugal pump.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a centrifugal pump, includes the motor and the pump body, the motor is fixed in on the mounting platform with the pump body, screw rod adjustable connection is passed through on the shock attenuation lower margin in mounting platform's four corners, the shock attenuation lower margin is located the mounting platform bottom, and shock attenuation lower margin both sides are provided with the fixed orifices, the mounting platform top is provided with lock nut, lock nut and screw rod threaded connection.
The shock absorption anchor is of a strip-shaped structure, and two mounting holes are formed in the top of the shock absorption anchor.
The spring that can follow the mounting hole axis direction and stretch out and draw back is provided with in the mounting hole, the natural length of spring is greater than the degree of depth of mounting hole.
The shock absorption anchor is made of rubber.
The utility model has the advantages that:
the utility model provides a centrifugal pump, the mounting platform of this centrifugal pump is fixed in the shock attenuation lower margin through the screw rod, and when the operation produced the vibration, the vibration conducts to the shock attenuation lower margin through the screw rod, because the shock attenuation lower margin adopts buffer material to make, can produce the deformation of small amplitude and offset the damage that vibrations caused to material rigid connection, extension equipment life also can have the noise that effectual reduction produced from this simultaneously.
Drawings
FIG. 1 is a schematic structural view of a centrifugal pump of the present invention;
FIG. 2 is a schematic structural view of a shock absorbing anchor;
FIG. 3 is a cross-sectional view of a shock absorbing anchor;
in the figure: the method comprises the following steps of 1-a motor, 2-a pump body, 3-a mounting platform, 4-a screw rod, 5-a damping foot margin, 6-a fixing hole, 7-a locking nut, 8-a mounting hole and 9-a spring.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, a centrifugal pump belongs to the technical field of delivery pumps, and can reduce damage and noise caused by vibration during pump operation.
The utility model discloses a centrifugal pump, including the motor 1 with the pump body 2, motor 1 is fixed in mounting platform 3 with the pump body 2 on. The four corners of the mounting platform 3 are adjustably connected to the damping anchor 5 through the screws 4, and the relative positions of the adjusting screws 4 and the damping anchor 5 facilitate the alignment adjustment of the butt joint position of the pipeline when the pump is mounted. The shock absorption anchor 5 is made of a buffer material, and can absorb shock generated in the running process and reduce noise generated by the shock absorption anchor. Shock attenuation lower margin 5 is located mounting platform 3 bottoms, and 5 both sides of shock attenuation lower margin are provided with fixed orifices 6, and shock attenuation lower margin 5 passes through 6 fixed mounting of fixed orifices on the working face. Mounting platform 3 top is provided with lock nut 7, and lock nut 7 and screw rod 4 threaded connection, lock nut 7 are used for preventing to take place to become flexible between screw rod 4 and the mounting platform 3.
Be provided with in the mounting hole 8 and follow the flexible spring 9 of 8 axis directions of mounting hole, the natural length of spring 9 is greater than the degree of depth of mounting hole 8, because the length of spring 9 is greater than the degree of depth of mounting hole 8, consequently after screw rod 4 selects into, spring 9 is in the state of compressed all the time, can play supplementary shock attenuation and the effect of supporting intensity on the one hand, on the other hand, owing to the rebound effort that is produced by the compression, has also played locking effect to between screw rod 4 and the shock attenuation lower margin 5.
The shock absorbing material 5 is made of rubber, and the rubber is a preferable buffer material in the embodiment.
The following describes the usage of the present invention with reference to the drawings.
The method comprises the following steps: fixedly mounting a damping anchor 5 at a use position through a fixing hole 6;
step two: fixing the assembled mounting platform 3 in a mounting hole 8 of a damping anchor 5 through a screw 4;
step three: the relative position relation between the centrifugal pump and the connecting pipeline is adjusted through the screw rod 4;
step four: fastening a locking nut 7 and installing a connecting pipeline;
step five: and (5) after the installation is finished, starting the equipment to operate.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
