Description

Technical Field

[0001] The utility model relates to the technical field of self-priming pumps, in particular to a self-priming pump with a leakage alarm mechanism. Background Technique

[0002] The self-priming pump belongs to a type of centrifugal pump, with a very compact internal structure. It relies on the rotation of the impeller by the shaft of the motor to suck the liquid. It is necessary to pre-fill the liquid into the pump housing and start the impeller for extraction to form a vacuum state inside, and then open the valve for the liquid to flow through.

[0003] Although the self-priming pump is an integral unit, the inlet and outlet pipes of this device are all externally connected structures, which need to be manually assembled and reinforced with flange plates, nuts, and bolts. If liquid leaks from the gaps, it will not only pollute the surrounding environment but also easily adhere to the surface of the pump body and corrode the housing, which is not conducive to the later maintenance of the self-priming pump.

[0004] Now, a new type of self-priming pump with a leakage alarm mechanism is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a self-priming pump with a leakage alarm mechanism to solve the problem of easy liquid leakage mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A self-priming pump with a leakage alarm mechanism, including a housing and a liquid outlet pipe. The liquid outlet pipe is fixed at the top of the housing. The liquid inlet pipe is fixed on the left side of the housing. An internal pipeline is installed between the housing, the liquid outlet pipe, and the liquid inlet pipe. A motor set is installed on the right side outside the housing, and an impeller is installed on the left side of the motor set. The top and the left side of the housing are respectively sleeved with a housing sleeve, and a hygrometer is installed in the housing sleeve. A dial is fixed outside the hygrometer. A silica gel ring is fixed at the notch of the housing sleeve. A sealing ring is installed between the housing sleeve and the housing.

[0007] Preferably, the silica gel ring is sleeved outside the liquid outlet pipe and the liquid inlet pipe, and the housing sleeve and the hygrometer are arranged concentrically.

[0008] Preferably, flange plates are fixed at the ends of the liquid outlet pipe and the liquid inlet pipe, and a groove is provided in the flange plate. A circular ring is inserted and fixed in the groove, and a filter box is fixed inside the circular ring. Thread grooves are respectively provided on both sides of the circular ring, and bolts are threadedly connected in the thread grooves. Threaded holes are respectively provided on both sides inside the groove.

[0009] Preferably, the bolts are embedded between the thread grooves and the threaded holes, and the circular ring is embedded in the groove.

[0010] Preferably, the filter box can slide in and out along the inner wall of the groove, and assembly holes are reserved around the outer side of the flange plate.

[0011] Preferably, a base is horizontally arranged below the housing, and a small ferrule is fixed to the left side of the top of the base. The small ferrule is sleeved on the outer side of the liquid inlet pipe. A large ferrule is fixed to the right side of the top of the base, and the large ferrule is sleeved on the outer side of the motor set. A support pad is arranged on the top of the base, and holes are respectively arranged at the four corners inside the support pad. A plug rod is fixed to the top of the support pad, and a spring is fixed between the top of the plug rod and the support pad. A sound-absorbing pad is fixed to the center of the top of the base.

[0012] Preferably, the spring is sleeved on the outside of the plug rod, and the plug rod can slide up and down along the hole.

[0013] Preferably, the sound-absorbing pad is attached to the bottom of the support pad, and the support pad can squeeze the spring along the plug rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The self-priming pump with a leakage alarm mechanism not only avoids liquid leakage of the pump body, realizes convenient installation of the filtering structure, but also reduces the generation of vibration.

[0015] (1) By sleeving a housing cover on the top and left side of the housing respectively, and fixing the housing covers at the assembly positions of the housing, the liquid outlet pipe and the liquid inlet pipe, the sealing ring is completely attached to the surface of the housing and fixed with screws. On the other side, it is reinforced by being sleeved with a silicone ring. The humidity meter filled inside not only avoids deformation of the housing cover, but also can display humidity data through the extended dial, facilitating people to detect the humidity here. If there is leakage, it can be known in time through the change of the humidity value.

[0016] (2) By fixing a filter box inside the ring, inserting the filter box into the liquid outlet pipe and the liquid inlet pipe respectively, and embedding the rings of both into the respective flange plates connected, and being limited by the groove, after aligning the thread groove and the screw hole, the bolt can be rotated for reinforcement, forming an interception structure inside the pipeline to avoid sundries falling into the housing and rubbing against the impeller to cause damage. If it is not needed, it can be taken out without affecting the use of the equipment.

[0017] (3) By fixing a sound-absorbing pad at the center of the top of the base, when the impeller rotates on the right side of the inner pipeline in the housing to suck liquid in a vacuum after starting the motor set, the housing will generate certain vibration, and then vertically squeeze the support pad along the plug rods at the four places below. The top of the four corners of the support pad is restricted on the plug rod by the spring, and the bottom squeezes the sound-absorbing pad, which not only absorbs noise but also slows down vibration, and the elastic force of the spring can quickly reset the support pad and the housing.
