Problems solved by technology

[0002] Centrifugal pumps are classified from different angles and have different names. Among them, circulating pumps are a common pump body structure and are widely used in daily life. At present, there are two main problems with traditional SPA circulating pumps: electric pump noise and electric pump leakage.
There are generally two types of motor fan blades: one type is external fan blades, and the other type is that the rotor balance column is designed in the shape of fan blades and die-cast together with the end ring, but as long as there are fan blades, no matter whether it is a large fan blade or Small wind blades, there must be ventilation noise; the water pump seal usually adopts a mechanical seal, and the seal is formed by friction between the dynamic and static rings, but as long as there is a mechanical seal, there must be a possibility of water leakage from the water pump seal
[0003] In order to solve the technical defects of poor sealing, high noise, short service life and fast wear of the SPA circulating pump in the prior art, the present invention proposes a special circulating pump for SPA

Abstract

The invention provides a special SPA circulating pump which comprises a pump case assembly (12), an impeller (10), bearings (18), a pump cover (7) and a motor (13). The impeller (10) is connected to the corresponding bearing (18) through a shaft sleeve in a sleeving mode. The impeller (10) makes contact with the pump cover (7) through a movable impeller opening cup (9) and a big O-shaped ring (8). The movable impeller opening cup (9) comprises a sleeve (20) and an end ring (21). The outer diameter of the end ring (21) is two to three times that of the sleeve (20). The outer wall of the shaft sleeve is sleeved with the sleeve (20). The end ring (21) is in interference fit with an inner hole of the pump cover (7). The motor (13) comprises a stator (17) with a winding and a rotor (16), wherein the stator (17) and the rotor (16) are located in a motor shell (19). The two ends of the rotor (16) are connected in series with a deep groove ball bearing head (15) and the impeller (10) through the bearings (18) correspondingly. The deep groove ball bearing head (15) is matched with a capacitor (14). The special SPA circulating pump is low in ventilation noise and capable of continuously and reliably operating in a moisture environment, and the problem that water leakage of a mechanical seal is caused by the quality or service life of the mechanical seal of a traditional circulating pump is solved.
