Description

Technical Field

[0001] The present application relates to the technical field of circulating pumps, and more specifically, to a boiler circulating pump protective cover. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or can be converted into mechanical energy through a steam power device, or mechanical energy can be converted into electrical energy through a generator. A circulating pump refers to a pump used to transport circulating liquid for reaction, absorption, separation, and absorption liquid regeneration in a device. Its head is low and is only used to overcome the pressure drop of the circulation system. A low-head pump can be used. In order to protect the circulating pump, a corresponding protective cover is usually installed on the circulating pump for protection.

[0003] According to the search, the Chinese patent with patent number CN217976729U discloses a circulating pump protective cover, including a pump body, a motor is arranged on one side of the pump body, a mounting seat is arranged at the bottom of the pump body, a cover body is sleeved on the outside of the pump body, and a heat sink and a filter plate are arranged on the side wall of the cover body adjacent to the motor from the inside to the outside. The utility model effectively protects the circulating pump by arranging a cover body on the outside of the pump body; the heat sink and the filter plate are arranged on the cover body to effectively dissipate heat, and also prevent the circulation pump motor from being affected by dust accumulation.

[0004] With respect to the above-mentioned related technologies, the applicant believes that, although the above-mentioned protective cover can achieve the protective effect on the circulating pump during use, the installation method of the protective cover is through bolts and screw holes. Since the working environment of the circulating pump is mostly a humid environment, the bolted connector is exposed to the outside and is easily affected by the environment, resulting in rust and oxidation, or affected by dust in the environment. In this state, it is easy to make the bolts difficult to remove, and the protective cover difficult to open, affecting the maintenance of the circulating pump. For this reason, we propose a boiler circulating pump protective cover. Utility Model Content
