Abstract

The invention discloses a centrifugal pump low in failure rate. The centrifugal pump comprises a pump body, an impeller, a pump cover, a machine seal gland, a suspension frame and a rotating shaft, wherein the pump cover is fixed to one side of the pump body, a pump cavity for installing the impeller is formed between the pump cover and the pump body, the suspension frame is fixed to one side of the pump cover, and the rotating shaft is supported in the suspension frame through a bearing; one end of the rotating shaft extends into the pump cavity, the impeller is arranged in the pump cavity ofthe pump body and is fixed at the end of the rotating shaft, and a machine sealing cavity is in a circular truncated cone shape; the cross section of the machine sealing cavity is in a trapezoid shape, and an air guiding channel is formed in the inner wall of the machine sealing cavity; the air guiding channel is connected with an air storage cavity in the pump cover, the upper portion of the airstorage cavity is connected with an exhaust channel, and a drainage channel is further formed in the inner wall of the machine sealing cavity; a cooling plate is further arranged in the machine sealing cavity, and the inner wall of the machine sealing cavity is subjected to surface enhanced modification. The centrifugal pump is low in fault rate, and has high market competitiveness and application and popularization value.

Description

technical field [0001] The invention relates to a centrifugal pump, in particular to a centrifugal pump with low failure rate. Background technique [0002] Centrifugal pump refers to the pump that transports liquid by the centrifugal force generated when the impeller rotates. It can transport more media. It is a common power machine in modern people's daily life and industrial production. The existing centrifugal pumps have problems such as high noise in operation, easy corrosion and damage of parts, unstable performance, high failure rate in operation, and short service life. Further improvement is urgently needed. Contents of the invention [0003] The object of the present invention is to provide a centrifugal pump with low failure rate aiming at the existing problems. [0004] The present invention is achieved through the following technical solutions: [0005] A centrifugal pump with a low failure rate, including a pump body, an impeller, a pump cover, a mechanical...
