[0024] See Figure 2-Figure 4 , the utility model provides a technical solution:

[0025] A centrally controlled, connected combination pump includes a first motor 1, a second motor 2, a first connecting sleeve 3, a second connecting sleeve 4, a high-pressure pump 5, a connecting plate 6, and a controller 7. The high-pressure pump 5 is fixedly disposed on one end of each of the first motor 1 and the second motor 2. The first connecting sleeve 3 is fixedly disposed on the other end of the first motor 1, and the second connecting sleeve 4 is fixedly disposed on the other end of the second motor 2. The end of the first connecting sleeve 3 mates with the end of the second connecting sleeve 4, and the first and second connecting sleeves 3 and 4 are fixedly connected via a connecting plate 6. One end of the controller 7 is disposed within the first connecting sleeve 3, and the other end of the controller 7 is disposed within the second connecting sleeve 4. The first motor 1 and the second motor 2 are coaxially arranged. Among them, the first motor 1 and the second motor 2 are both motors in the prior art, the two high-pressure pumps 5 are both prior art and are driven to rotate by the first motor 1 and the second motor 2 respectively, the controller 7 is prior art, and its function is to control the rotation of the first motor 1 and the second motor 2, the first connecting sleeve 3 and the second connecting sleeve 4 are used to install the controller 7 and play a connecting role, the first connecting sleeve 3 is fixedly connected to the first motor 1, and the second connecting sleeve 4 is connected to the second motor 2, and the function of the connecting plate 6 is to fix the first connecting sleeve 3 and the second connecting sleeve 4 together.

[0026] In some embodiments, a first locating pin hole 8 is provided on the end of the first connecting sleeve 3, and a second locating pin hole 9 is provided on the end of the second connecting sleeve 4. The first locating pin hole 8 and the second locating pin hole 9 respectively cooperate with the two ends of the locating pin 10. Two locating pins 10 are provided between the first connecting sleeve 3 and the second connecting sleeve 4. The two locating pins 10 are arranged opposite to each other. Under the action of the two locating pins 10, the first connecting sleeve 3 and the second connecting sleeve 4 can be better positioned during the assembly process.

[0027] In some embodiments, the first motor 1 is sealed and fixedly connected to the first connecting sleeve 3, the second motor 2 is sealed and fixedly connected to the second connecting sleeve 4, and the end of the first connecting sleeve 3 is sealed and matched with the end of the second connecting sleeve 4. A sealing ring 11 is provided between the first connecting sleeve 3 and the second connecting sleeve 4. A first sealing groove 12 that cooperates with the sealing ring 11 is provided on the end of the first connecting sleeve 3, and a second sealing groove 13 that cooperates with the sealing ring 11 is provided on the end of the second connecting sleeve 4. In order to ensure that external water or dust does not damage the controller 7, an integrated sealing connection is adopted between the first motor 1 and the first connecting sleeve 3, and between the second motor 2 and the second connecting sleeve 4, and the sealing ring 11 in the prior art is used for sealing between the first connecting sleeve 3 and the second connecting sleeve 4. The provision of the first sealing groove 12 and the second sealing groove 13 makes the sealing effect of the sealing ring 11 better. A through cable hole is provided on the first connecting sleeve 3 or the second connecting sleeve 4, and the power cable is sealed and matched with the cable hole.

[0028] In some embodiments, two first connection blocks 14 are symmetrically provided on the outer wall of the first connection sleeve 3, and two second connection blocks 15 are symmetrically provided on the outer wall of the second connection sleeve 4, respectively cooperating with the first connection blocks 14. The first connection blocks 14 and the second connection blocks 15 are fixedly connected by a connection plate 6. The ends of the connection plate 6 can be fixed to the first connection blocks 14 and the second connection blocks 15 by screws. The provision of the first connection blocks 14 and the second connection blocks 15 facilitates the installation of the screws and prevents the ends of the screws from extending into the interior of the first connection sleeve 3 and the second connection sleeve 4, resulting in poor sealing effect.

[0029] In some embodiments, the first connecting block 14 is provided with a first through hole, the first through hole is provided with a first connecting rod 16 that cooperates with the first through hole, the second connecting block 15 is provided with a second through hole, the second through hole is provided with a second connecting rod 17 that cooperates with the second through hole, and the two ends of the first connecting rod 16 are respectively connected to the two ends of the second connecting rod 17 through connecting plates 6. The first connecting rod 16 and the second connecting rod 17 are arranged parallel to each other. Among them, two connecting plates 6 can be used for connection under the action of the first connecting rod 16 and the second connecting rod 17. Therefore, four connecting plates 6 are used to connect the first connecting sleeve 3 and the second connecting sleeve 4, making the connection between the first connecting sleeve 3 and the second connecting sleeve 4 more stable. The first connecting rod 16 and the second connecting rod 17 are both bolts, and the other ends of the bolts are fixed with nuts.

[0030] In some embodiments, the outer diameter of the first motor 1 is larger than the outer diameter of the first connecting sleeve 3, and the outer diameter of the second motor 2 is larger than the outer diameter of the second connecting sleeve 4. A stepped shaft arrangement is formed between the first motor 1 and the first connecting sleeve 3, and a stepped shaft arrangement is formed between the second motor 2 and the second connecting sleeve 4. This allows the connecting plate 6 to protrude less after connection, making the structure of the entire combined pump more compact.
