Embodiment

[0031] Such as figure 1 , figure 2 , image 3 As shown, the self-priming pump with a sealing mechanism includes an eccentric wheel 1, a first screw 801 and a second screw 802. One end of the eccentric wheel 1 is connected to a motor 2, and the other end of the eccentric wheel 1 is connected to a transmission wheel 3. The wheel 3 moves through the support seat 4 and is inserted into the valve seat 7. The valve seat 7 is sleeved with the pump casing 8, the first screw 801 connects the pump casing 8, the support seat 4 and the motor 2, and the second screw 802 connects the pump casing 8 and the motor 2. Support seat 4;

[0032] The drive wheel 3 is provided with a first annular groove 301 and a threaded hole 302, the pump casing 8 is provided with a second annular groove 803, and the second annular groove 803 is provided with a second sealing groove 804;

[0033] The valve seat 7 is sleeved with a rubber diaphragm 5, and a sealing ring 501 is connected to the rubber diaphragm...

Abstract

The invention relates to the technical field of self-priming pumps, in particular to a self-priming pump with a sealing mechanism. One end of an eccentric wheel is connected with a motor, the other end of the eccentric wheel is connected with a transmission wheel, the transmission wheel movably penetrates through a supporting seat and is inserted into a valve seat, the valve seat is sleeved with a pump shell, a first screw is connected with the pump shell, the supporting seat and the motor, and a second screw is connected with the pump shell and the supporting seat; and the transmission wheel is provided with a first annular groove and a threaded hole. A sealing ring on a rubber diaphragm is embedded into the first annular groove, sealant is arranged between the first annular groove and the sealing ring to prevent water from overflowing between a first piston and the rubber diaphragm, a first sealing groove and a second sealing groove form a sealing cavity, sealing lubricating grease is injected into the sealing cavity to ensure the sealing performance of the sealing cavity, the water is prevented from overflowing between the rubber diaphragm and the pump shell, and the situation that the efficiency and the self-suction performance of the pump are affected due to loss of the rubber diaphragm in the using process is avoided.

Description

technical field [0001] The invention relates to the technical field of self-priming pumps, in particular to a self-priming pump with a sealing mechanism. Background technique [0002] The self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. [0003] The self-priming pump is equipped with a sealing mechanism to prevent liquid leakage, in which the rubber diaphragm plays a major role in the sealing mechanism, but the rubber diaphragm will be worn out during long-term use, affecting the sealing effect and affecting the efficiency of the pump and self-priming performance. Contents of the invention [0004] The invention aims at the deficiencies of the prior art and provides a self-priming pump with a sealing mechanism. [0005] The present invention realizes solving above-mentioned technical problem by followin...
