Description

Technical Field

[0001] The utility model relates to the field of self-priming pumps, in particular to a laminated synchronous self-priming pump. Background Art

[0002] Water pumps are indispensable in current industrial and civil production and life, and there are various ways to transport fluids according to different actual working conditions. Traditional negative pressure water supply pumps or solutions basically include submersible pumps, submersible pumps (axial flow pumps), ordinary self-priming pumps, bottom valve injection pumps, vacuum drainage pumps, underground pump room pumps, etc. Although these forms have their own characteristics, they have been found through long-term use that they also have many disadvantages such as poor self-priming ability, long start-up time, small flow, low head, high project investment, high maintenance cost, poor working conditions, and harsh working environment.

[0003] After searching, a Chinese utility model patent disclosed a laminated compressor synchronous self-priming pump with publication number CN201902339U, including: a laminated compressor, a tuning fork level sensor, a solenoid valve, a float valve, a fluid detection chamber, a fully automatic electric control cabinet, a pump body, a drive motor, and a common base.

[0004] In the above patent application, the gas and liquid at the inlet end of the pump are discharged synchronously from the outlet pipeline, so that the water discharge time after startup is zero seconds or very short, and the self-priming function is achieved. However, when the above equipment is in use, since it contains multiple devices such as a laminated compressor and a drive motor, in actual work, the equipment itself will vibrate greatly, thereby emitting a lot of noise, which greatly affects the lives of nearby residents and the working environment of workers. At the same time, when the above equipment is working, the silt in the sewage is not intercepted and filtered, which will cause the outlet end of the equipment to be blocked, affecting the service life of the entire equipment. Therefore, a laminated synchronous self-priming pump is urgently needed to solve this problem. Utility Model Content

[0031] Working principle:

[0032] When working, the worker starts the servo motor 2 through the controller 3. Under the cooperation of the coupling 61, the transmission rod 62 will drive the impeller seat 63 to rotate at a high speed in the inner cavity of the pump housing 5. At this time, the external sewage can be sucked into the inner cavity of the pump housing 5 through the input pipe 51, and then discharged from the output pipe 52. Thus, through the above, the whole equipment can complete the self-priming function of sewage.

[0033] By setting the input pipe 51 below the pump housing 5, the output pipe 52 above the pump housing 5, and the interception plate 8, the silt in the input sewage can be effectively intercepted and disposed, thereby effectively avoiding the silt accumulation in the pump housing 5 and causing the blockage of the output pipe 52, reducing the probability of failure of the entire equipment, and improving the work efficiency of workers. After the sewage is intercepted by the interception plate 8, the silt will continue to accumulate below the inner cavity of the pump housing 5. After the entire equipment is shut down, the silt can be uniformly removed and cleaned through the sewage pipe 53, ensuring the efficiency of the subsequent use of the entire equipment;

[0034] After the interception plate 8 has been used for a period of time, the worker can directly pull the handle 82 to the left to make the interception plate 8 withdraw from the pump housing 5. At this time, the limiting piece 95 will flip and drive the rotating rod 92 to rotate, so that the torsion spring 94 will shrink. At this time, the worker fixes the position of the limiting piece 95. After the worker replaces the new interception plate 8, the limiting piece 95 is released. Under the elastic force of the torsion spring 94 itself, the limiting piece 95 will be against the side wall of the interception plate 8 again to fix it. Therefore, through the above, the device can realize the function of quickly replacing the interception plate 8, which improves the work efficiency of the workers to a certain extent.

[0035] When the entire equipment is working, the pump housing 5 will inevitably vibrate. At this time, the pump housing 5 can transmit the vibration force to the support seat 4 and make it slide to the lower part of the inner cavity of the equipment base 1. Since the positions of the upper hinge plate 71 and the lower hinge plate 76 are fixed, the limit rod 73 will rotate downward at this time, and one end of the limit rod 73 will slide into the inner cavity of the upper hinge plate 71. Through the setting of the buffer spring 74, the up and down vibration force of the support seat 4 can be absorbed, thereby effectively reducing the vibration amplitude of the pump housing 5 and reducing the propagation of noise, thereby ensuring the health of the living environment of nearby residents.

[0036] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
