Description

Technical Field

[0001] The utility model relates to the technical field of double-suction pumps, in particular to an anti-water accumulation type double-suction pump. Background Art

[0002] A double-suction pump is a special centrifugal pump with the notable feature of having two suction chambers, namely an inlet (also called single-stage or multi-stage) and an outlet (also called multi-stage or two-stage). When working, the double-suction pump simultaneously sucks liquid through two inlets to achieve two-way suction, and then the liquid is pushed to the outlet and discharged through the rotation of the rotor. This design enables the double-suction pump to handle large flow and high pressure liquids, and is widely used in industrial production, construction engineering, water supply and drainage systems and other fields.

[0003] The patent with publication number CN206889266U discloses a double-suction pump that can prevent water accumulation in the groove. The patent achieves the effect of controlled discharge of water accumulated in the groove inside the double-suction pump through the arrangement of a driving motor, a rotating screw, a screw movable sleeve, a connecting shaft and a right clamping plate, and achieves the effect of increasing the normal use time of the double-suction pump.

[0004] However, the above patent still has the following problems in actual operation:

[0005] During the use of traditional double-suction pumps, water is prone to accumulation inside the pump body, which will affect the normal operation and efficiency of the pump and may even cause equipment damage. At the same time, the double-suction pump will vibrate during operation. Long-term vibration will not only affect the stability of the equipment, but may also interfere with the surrounding environment and other equipment. Traditional double-suction pumps may have inconvenient operation in drainage and maintenance. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to solve the problem that water is easily accumulated inside the pump body during the use of traditional double-suction pumps, which will affect the normal operation and efficiency of the pump and may even cause damage to the equipment. At the same time, the double-suction pump will vibrate during operation. Long-term vibration will not only affect the stability of the equipment, but also may interfere with the surrounding environment and other equipment. Traditional double-suction pumps may have technical problems in drainage and maintenance. Please refer to Figure 1-4 , this utility provides the following technical solutions:

[0024] A water-proof double-suction pump comprises a motor 1, a bearing seat 2 and a double-suction pump body 3. The motor 1 and the double-suction pump body 3 are respectively arranged on both sides of the bearing seat 2. A shock-absorbing base 4 is arranged at the bottom of the motor 1, the bearing seat 2 and the double-suction pump body 3. A drainage pedal 5 is arranged on one side of the shock-absorbing base 4. A connecting plate 6 is connected to one side of the drainage pedal 5. The connecting plate 6 extends into the interior of the shock-absorbing base 4. The middle part of the connecting plate 6 is connected to the interior of the shock-absorbing base 4 through an axle pin. A drainage component 7 is arranged below the double-suction pump body 3. The structure design of the whole water-proof double-suction pump is compact. The connection between the components is reasonable and firm, so that the equipment as a whole has good stability and reliability. The setting of the drainage pedal 5 and the connecting plate 6 makes the maintenance of the drainage component 7 more convenient. The operator can operate the connecting plate 6 and the drainage component 7 by stepping on the drainage pedal 5 to turn the drainage function on and off, thereby improving the maintainability of the equipment. Due to the dual protection of shock absorption and drainage functions, the anti-water accumulation double-suction pump can operate in a more stable and reliable state, reducing failures and downtime caused by vibration and water accumulation, thereby improving the work efficiency of the equipment.

[0025] In this embodiment, the shock-absorbing base 4 includes an outer base body 41, and a mounting plate 42 is arranged on the top of the outer base body 41. The mounting plate 42 is fixedly connected to the bottom of the motor 1, the bearing seat 2 and the double-suction pump body 3. A guide column 44 is vertically arranged at the edge of the inner part of the outer base body 41, and a shock-absorbing spring 47 is arranged around the guide column 44. A through hole matching the guide column 44 is opened on the mounting plate 42, and the mounting plate 42 is placed on the guide column 44 through the through hole. A pad 46 is arranged at the edge of the top of the outer base body 41, and a circular hole matching the guide column 44 is opened on the pad 46. The guide column 44 passes through the circular hole of the pad 46, and the pad 46 is connected to the outer base body 41 by a fixing bolt 45. An auxiliary spring 43 is arranged inside the outer base body 41, and the two ends of the auxiliary spring 43 are respectively connected to the outer base body 41 and the mounting plate 42. The design of the shock-absorbing base 4 combines the guide column 44 and the shock-absorbing spring 47, as well as the use of the auxiliary spring 43, to form a multi-level shock-absorbing system. When the vibration generated by the motor 1 and the double-suction pump body 3 is working, the vibration is transmitted to the shock-absorbing base 4 through the mounting plate 42. These springs can effectively absorb and disperse the vibration energy, thereby significantly reducing the impact of the vibration on the equipment itself and the surrounding environment, which not only improves the stability and reliability of the equipment and extends the service life of the equipment, but also helps to reduce operating noise and improve the working environment.

[0026] In this embodiment, the drainage assembly 7 includes a drainage pipe 71, and a pump chamber 31 is opened inside the double-suction pump body 3. The top of the drainage pipe 71 passes through the double-suction pump body 3 and enters the pump chamber 31. The bottom of the drainage pipe 71 passes through the top of the shock-absorbing base 4 and extends into the shock-absorbing base 4. Side support plates 72 are arranged on both sides of the drainage pipe 71. A return spring 73 is arranged on the top of the side support plate 72. The side support plate 72 is arranged below the connecting plate 6. A sealing sheet 76 is provided on the top of the drain pipe 71, and the sealing sheet 76 is fittedly arranged at the bottom of the pump chamber 31. Through holes 75 are opened on both sides of the top of the drain pipe 71, and the through holes 75 are opened below the sealing sheet 76. The bottom of the drain pipe 71 is connected to a water guide hose 74, and the water guide hose 74 extends to the outside of the shock-absorbing base 4. The design of the drain component 7 can effectively prevent water accumulation in the pump body 3 of the double-suction pump. When water accumulates in the pump body, the drainage pedal 5 is stepped on from the outside, the connecting plate 6 is lifted up and the drain pipe 71 is lifted up through the side support plate 72. The accumulated water will enter the drain pipe 71 through the through hole 75 at the top of the drain pipe 71, and be smoothly discharged to the outside of the shock-absorbing base 4 through the water guide hose 74, thereby avoiding the potential impact of the accumulated water on the normal operation of the pump. The combined structure of the side support plate 72 and the reset spring 73 can drive the drainage structure to automatically reset, and the operation is quick and convenient.

[0027] The working principle of the above content is: the motor 1 drives the double suction pump body 3 to work through the bearing seat 2. During the working process, the vibration generated when the pump body is working will be transmitted to the mounting plate 42, and the mounting plate 42 will be elastically buffered by the shock absorbing spring 47 on the guide column 44, thereby reducing the impact of the vibration on the pump body and the entire system. At the same time, the auxiliary spring 43 also provides additional shock absorbing effect to ensure the stable operation of the pump. The design of the drainage component 7 is mainly used to prevent water accumulation inside the pump body. When it is necessary to drain the pump chamber 31 inside the pump body 3, the drainage pedal 5 is stepped on from the outside, the connecting plate 6 is lifted up and the drainage pipe 71 is lifted up through the side support plate 72. The accumulated water will enter the drainage pipe 71 through the through hole 75 at the top of the drainage pipe 71, and the accumulated water will be discharged through the drainage pipe 71 and guided to the outside of the shock absorbing base 4 through the water guide hose 74, thereby preventing the accumulation of water from affecting the normal operation of the pump. After the drainage is completed, the drainage pedal 5 is released, and the side support plate 72 receives the action of the reset spring 73 to drive the drainage pipe 71 to reset.
