[0040] A split-case pump is a mechanical device that transfers liquid or gas from one position to another. The split-case pump includes an impeller, a pump body, and a pump shaft. The impeller is installed in the pump body and connected to the pump shaft, and the pump shaft is directly driven by a motor. The pump body has a suction port and a discharge port.

In the horizontal use state, the extending direction of the motor output shaft coincides with or is parallel to the horizontal direction, and the second support seat provides a support foundation for the pump body. In the vertical use state, the extending direction of the motor output shaft coincides with or is parallel to the vertical direction, the first support seat is fixed on an installation surface such as the ground, making full use of the longitudinal space and reducing the floor area. Both the first support seat and the second support seat are used to provide a support foundation for the pump body and resist the torque and deformation generated by the pump body due to torque and vibration during operation, enabling the split-case pump to operate smoothly, realizing the vertical and horizontal dual-use of the split-case pump, and facilitating the selection of vertical or horizontal use according to the size of the space.

[0046] In specific implementation, taking the split-case pump as a centrifugal pump as an example, it includes a pump body 100, a pump cover 130, a pump shaft 120, an impeller, a sealing ring, a shaft sleeve, and a bearing assembly. The impeller is connected to the shaft through the shaft sleeve, and the motor 200 is connected to the pump shaft 120 through a coupling to achieve power transmission. The suction port and discharge port of the pump can be located below the axis of the pump shaft 120. The pump casing is split along the axis of the pump shaft 120, with the upper part being the pump cover 130 and the lower part being the pump body 100 casing. The center line of the impeller is perpendicular to the axis of the pump shaft 120.

[0047] The pump shaft 120 connects the motor 200 and the impeller, transmits the power of the motor 200 to the impeller, and causes the impeller to rotate at a high speed, thereby generating a centrifugal force to suck and discharge the fluid from the pump body 100. Components such as the impeller, retaining sleeve, and shaft sleeve are fixed at a certain position on the pump shaft 120 through the positive and reverse locking nuts at both ends of the pump shaft 120. Both ends of the pump shaft 120 are connected to bearings. The bearings are used to bear the radial load and axial load of the pump body 100 to support the rotor weight and dynamic load of the pump body 100. In some embodiments, the pump shaft 120 is also connected to an end cover, which provides support for the pump shaft 120.

[0048] The motor 200 is installed on the motor bracket 300. The motor 200 is connected to the pump body 100 through a coupling to achieve force transmission. The coupling can compensate for the relative displacement between the pump shaft 120 and the output shaft of the motor 200, reduce the difficulty of alignment, play a buffering role, and change the natural vibration frequency and local vibration of the shaft. The specific structure of the coupling is not limited in this application. Exemplarily, the coupling can be a claw-type elastic coupling, an elastic pin coupling, a diaphragm coupling, a rigid coupling, a toothed coupling, etc. The pump body bracket 400 is arranged on the first support seat 500 and is detachably or fixedly connected to the first support seat 500.

In the horizontal use state, the extending direction of the output shaft of the motor 200 coincides with or is parallel to the horizontal direction, and the second support seat 600 provides a support foundation for the horizontal use of the pump body 100. In the vertical use state, the extending direction of the output shaft of the motor 200 coincides with or is parallel to the vertical direction. The first support seat 500 is fixed on an installation surface such as the ground, making full use of the longitudinal space and reducing the floor area. Both the first support seat 500 and the second support seat 600 are used to provide a support foundation for the pump body 100 and resist the torsion and deformation generated by the torque and vibration during the operation of the pump body 100, enabling the pump body 100 to operate smoothly, realizing the vertical-horizontal dual-use of the split-case pump, and facilitating the selection of vertical or horizontal use according to the space size.

[0050] In some possible implementation manners, for the vertical and horizontal dual-purpose split-case pump provided by the embodiments of the present application, the motor bracket 300 includes a first connecting plate 310 and a second connecting plate 320. The first connecting plate 310 is disposed on the second connecting plate 320. The second connecting plate 320 is detachably connected to the pump body bracket 400, and the first connecting plate 310 is used for detachably connecting to the motor 200.

[0051] In some embodiments, the motor bracket 300 includes a first connecting plate 310, a connecting frame, and a second connecting plate 320. The first connecting plate 310 and the second connecting plate 320 are respectively disposed on the upper and lower portions of the connecting frame. A connecting cavity is formed inside the connecting frame. The delivery shaft and the coupling portion of the motor 200 are disposed inside the connecting cavity. The delivery shaft of the motor 200 is connected to the coupling to achieve transmission. A plurality of threaded holes are provided on the second connecting plate 320, and screws or bolts pass through the threaded holes to be connected to the pump body bracket 400, facilitating the disassembly and assembly of the motor bracket 300 and the pump body bracket 400. A plurality of threaded holes are provided on the first connecting plate 310, and screws or bolts pass through the mounting holes of the motor 200 to be threadedly connected to the threaded holes, facilitating the disassembly and assembly of the motor bracket 300 and the motor 200.

[0052] It can be understood that the motor bracket 300 is detachably connected to the pump body bracket 400 and the motor 200 respectively. When it is necessary to replace the motor 200 with different sizes, there is no need to disassemble and assemble the motor bracket 300, and only the motor 200 needs to be replaced, which is convenient for adapting to different motors 200.

[0053] In some possible implementation manners, for the vertical and horizontal dual-purpose split-case pump provided by the embodiments of the present application, a plurality of connection positions to be connected are provided on the first connecting plate 310, and the connection positions to be connected are used for connecting to the motor 200.

The diameter of the first connecting plate 310 is larger than the diameter of the second connecting plate 320, enabling the first connecting plate 310 to provide a larger support area, which is suitable for motors 200 with different sizes and installation positions.

[0055] The caliber of the connecting cavity at the end facing the pump body 100 is less than or equal to the caliber of the connecting cavity at the end facing the motor 200.

[0056] In some embodiments, a vibration damping device is further provided on the motor bracket 300.

[0057] In some possible implementation manners, for the vertical and horizontal dual-purpose split-case pump provided by the embodiments of the present application, the pump body bracket 400 includes a main body 410 and a reinforcing member 420.

[0058] Specifically, the pump body bracket 400 is disposed on the first support base 500 and is detachably connected to the first support base 500. The pump body bracket 400 includes a main body 410 and a reinforcing member 420. A platform is provided on the upper part of the main body 410 for placing and connecting to the motor bracket 300.

The reinforcing member 420 is spaced around the circumference of the main body 410 to facilitate enhancing the bearing capacity of the main body 410.

[0060] In some embodiments, the first support base 500 in the embodiments of the present application includes a base and anchor bolts. The base is the main body of the first support base 500, and its size can be designed according to the size and dimensions of the pump body 100, and the present application does not limit this. The anchor bolts are disposed on the base and are used to fix the base on the installation surface, such as the ground. Reserved holes are provided on the base. The anchor bolts pass through the reserved holes of the base and are connected to the fixing member on the installation surface through nuts.

[0061] In some embodiments, adjusting shims are further provided on the base.

Among them, the first support base 500 may further be provided with a drainage structure. Exemplarily, a drainage groove is provided at the bottom of the first support base 500 to prevent water from accumulating on the base and causing the first support base 500 to corrode and age.

[0062] In some embodiments, the lower end surface of the pump body 100 is flush with the upper end surface of the first support base 500.

[0063] On the one hand, the first support base 500 provides support for the pump body 100, and on the other hand, it has to resist the torsion and deformation generated by the pump body 100 due to torque and vibration during operation.

[0064] In some embodiments, the base includes an upper base plate and a support body, the upper base plate cover is arranged on the support body, the upper base plate and the support body are arranged to form a support cavity, the anchor bolts are arranged on the support body, and reinforcing ribs are arranged on the circumference of the upper base plate, and the reinforcing ribs are arranged obliquely toward the support body. There are multiple support bodies, and each support body is arranged at intervals to divide the support cavity into multiple vibration-damping cavities. The vibration-damping cavity is filled with a vibration-damping medium to achieve a certain vibration-damping and buffering effect. The vibration-damping medium can be rubber, viscoelastic material, polyurethane foam or damping material, etc., and the present application does not limit this.

[0066] In some embodiments, the cross-sections of the vibration-damping cavities may be the same or different, and may be symmetrical along a reference line so that the base is evenly stressed. In some embodiments, the cross-section of the vibration-damping cavity may be circular, rectangular, honeycomb, or prismatic, etc., and this application does not limit this.

[0067] The pump body bracket 400 in the embodiment of the present application, on the one hand, provides support for the motor bracket 300, and on the other hand, is integrated with the first support seat 500 and the second support seat 600, and can resist the torsion and deformation generated by torque and vibration during the operation of the pump body 100, so that the split pump can run smoothly.

[0068] In some possible implementations, the vertical and horizontal split pump provided in the embodiment of the present application is further provided with a connecting ring 430 on the pump body bracket 400. The connecting ring 430 is arranged on the side of the pump body bracket 400 facing the motor bracket 300, and the connecting ring 430 is used to connect to the lifting device.

[0069] In a specific implementation, a connecting ring 430 is provided at the top of the pump body support 400, and the connecting ring 430 is connected to the hook of the lifting device to facilitate lifting the pump body support 400. The number of connecting rings 430 can be multiple, and they are arranged at intervals on the circumference of the pump body support 400, for example, the number of connecting rings 430 is four, and they are arranged at intervals at the four corners of the connecting ring 430.

[0070] The connecting ring 430 in the embodiment of the present application is convenient for connection with a lifting device, such as a hook, to achieve lifting and transportation.

[0071] In some possible implementation manners, for the vertical and horizontal dual-purpose split-case pump provided by the embodiments of the present application, the first distance of the pump body 100 is equal to the second distance of the pump body 100, and the extending direction of the first distance is perpendicular to the extending direction of the second distance.

[0072] Specifically, the first distance of the pump body 100 in the embodiments of the present application is Figure 5 the distance A as shown, and the second distance of the pump body 100 is Figure 4 the distance B as shown. In this way, whether in the vertical use state or the horizontal use state, the center of gravity of the pump body 100 remains unchanged, the force can be evenly distributed, and the pump can operate stably.

[0073] In some possible implementation manners, the vertical and horizontal dual-purpose split-case pump provided by the embodiments of the present application further includes a support assembly 700.

One end of the first support member is connected to the pump body 100, and the other end is connected to the second support member. One end of the second support member is connected to the first support member, and the other end is connected to the first support seat 500 or the second support seat 600. In some embodiments, the extending direction of the first support member is perpendicular to the extending direction of the second support member.

[0075] A connection disk is disposed on the side of the second support member facing the first support seat 500 or the second support seat 600. Connection holes are provided on the connection disk. The number of connection holes is multiple, and they are spaced around the circumference of the connection disk. Screws or bolts pass through the connection holes to connect the second support member to the first support seat 500 or the second support seat 600.

[0076] Relying solely on the feet of the pump body 100, the middle part of the pump body 100 bears more force, and the weight of the pump body 100 will be concentrated entirely on the feet, with a relatively large bearing force. When the pump body 100 operates, it is prone to jitter, affecting the operation of the split-case pump. By means of the support assembly 700, the force on the pump body 100 is evenly distributed, the vibration during pump operation is reduced, and its stability is enhanced.

[0077] In some possible implementation manners, for the vertical and horizontal dual-purpose split-case pump provided by the embodiments of the present application, the number of support assemblies 700 is multiple, and each support assembly 700 is spaced around the circumferential side of the pump body 100.

[0078] In some other embodiments, the number of the support components 700 is plural, and the sizes of the support components 700 may be the same or different. Exemplarily, the number of the support components 700 is four, which are arranged around the circumference of the pump body 100 at intervals. Taking the pump shaft 120 line as the boundary, the sizes of the adjacent support components 700 on the same side of the same pump shaft 120 line are the same, so as to make the pump body 100 as symmetrical as possible, facilitate the uniform force on the pump body 100, and reduce vibration. In some embodiments, the end face of the first support member is flush with the end face of the pump body 100.

[0079] In some possible implementation manners, for the vertical and horizontal dual-purpose split-case pump provided by the embodiments of the present application, the pump body 100 includes a pump housing 110, a pump shaft 120 and a pump cover 130.

In some embodiments, the pump shaft 120 is further connected to the pump cover 130, which provides support for the pump shaft 120.

[0081] In the vertical and horizontal dual-purpose split-case pump in the embodiments of the present application, by connecting the pump shaft 120 to the pump cover 130, the running stability of the pump shaft 120 is increased and the vibration is reduced.

[0082] The present application does not limit the material of the pump body 100. Exemplarily, the material of the pump body 100 may be copper, cast iron, stainless steel, alloy, etc. The pump body 100 and the pump cover 130 form a rotating cavity, and the impeller is arranged in the rotating cavity.

[0083] In some possible implementation manners, for the vertical and horizontal dual-purpose split-case pump provided by the embodiments of the present application, the extending direction of the first support seat 500 is perpendicular to the extending direction of the second support seat 600.

[0084] In the vertical use state, the extending direction of the output shaft of the motor 200 coincides with or is parallel to the vertical direction. The first support seat 500 provides a support basis for the vertical use of the pump body 100, and resists the torsion and deformation generated by the pump body 100 due to torque and vibration during operation. In the horizontal use state, the extending direction of the output shaft of the motor 200 coincides with or is parallel to the horizontal direction. The second support seat 600 provides a support basis for the horizontal use of the pump body 100, and resists the torsion and deformation generated by the pump body 100 due to torque and vibration during operation.

[0085] It should be noted that the left end face of the pump body 100 is flush with the end face of the second support seat 600.

[0086] The second support seat 600 is arranged on one side of the first support seat 500. The pump body 100 is connected to the second support seat 600. Exemplarily, the second support seat 600 includes a first top plate, a second bottom plate and a connecting plate. The first top plate and the second bottom plate are connected by the connecting plate, and the connecting plate is connected to the first support seat 500. A support portion is arranged between the first top plate and the second bottom plate. The first top plate and the second bottom plate are arranged opposite to each other. One end of the support portion is connected to the first top plate, and the other end of the support portion is connected to the second bottom plate. The embodiment of the present application does not limit the connection manner between the connecting plate and the first support seat 500. For example, the connection manner between the connecting plate and the first support seat 500 can be welding or bolt connection. The support portion includes a plurality of support rods, which are arranged at intervals between the first top plate and the second bottom plate to enhance its support strength.

[0087] In some embodiments, connection holes are arranged on the first top plate. Bolts pass through the installation positions of the pump body 100 and are connected to the connection holes, so that the pump body 100 is connected to the first top plate, and the pump body 100 is fixed on the second support seat 600. The number and positions of the connection holes match the installation positions of the pump body 100 to achieve alignment and fixation.

[0088] Wherein, the second support seat 600 further includes auxiliary support rods. One end of each auxiliary support rod is connected to the second support seat 600, and the other end is connected to the first top plate. The embodiment of the present application does not limit the number of the auxiliary support rods. For example, the number of the auxiliary support rods is one. The first top plate is square, and the auxiliary support rod is arranged along any diagonal line of the first top plate. Or the number of the auxiliary support rods is two. Both the first top plate and the second bottom plate are square, and each auxiliary support rod is arranged along any diagonal line of the first top plate or the second bottom plate. The two auxiliary support rods can be arranged relatively staggeredly in an X shape. The auxiliary support rods can adjust the installation positions according to the installation angle and the center-of-gravity distribution of the pump body 100, so that the pump body 100 is stressed evenly and the stability of the pump body 100 is enhanced.

[0089] It should be noted that protective layers are arranged on both the second support seat 600 and the first support seat 500 to improve their corrosion resistance.

[0090] In the embodiment of the present application, the first support seat 500 and the second support seat 600 are perpendicular to each other, so that the installation surface is horizontal and flat, which is convenient for the horizontal and vertical installation of the pump body 100.
