[0002] In air-conditioning systems, the flow power of cooling circulating water comes from the water pump used to circulate cooling water, which is called a refrigeration pump in the industry. In order to improve the efficiency and performance of air-conditioning systems, double-suction centrifugal pumps are widely used as air-conditioning refrigeration pumps.

[0003] The bearing bodies of the existing drive-end bearing component and the tail-end bearing component are generally respectively arranged at the two ends of the pump shaft, and the bearing cover is generally arranged on the pump shaft and supported by the bearing body. In order to fix the bearing body, it is generally necessary to set protruding semicircular supports at both ends of the pump shaft. When the bearing body is fixed on the protruding semicircular support, it cannot be positioned upward, and only the lower semicircle of the semicircular support plays a supporting role. Therefore, the pump body is prone to vibration, the running stability is poor, and the service life of the bearing is reduced. At the same time, the existing bearing body cannot discharge waste oil (grease that has lost its lubricating effect). It can only be discharged by removing the bearing body, which increases the user's maintenance cost. For this reason, we propose an efficient and silent double-suction air-conditioning pump bearing component to solve the above problems. Utility Model Content
