Problems solved by technology

[0002] At present, the shaft sealing device of the acid pump basically adopts packing seal, and for the special acid pump of the acid low temperature recovery system, the temperature of the acid is generally more than 200 degrees, so the volatility of the acid is particularly strong, and the ordinary packing seal cannot be very It is very difficult to prevent the escape of acid gas, and the working environment is harsh. At the same time, due to the lack of good lubrication and cooling, the heat of the acid is transmitted through the pump shaft, which makes the working temperature of the motor and bearings high, which directly affects the working safety and service life of the acid pump.

Abstract

The invention discloses an acid pump. The acid pump is provided with a shaft seal device, wherein the shaft seal device comprises a fixedly arranged stuffing box and a fixedly arranged baffle ring; the stuffing box is provided with a lower cavity; a thread sleeve is arranged in the lower cavity, fixedly connected with a pump shaft, and in sealed fit with the radial direction of the pump shaft; the upper part of the baffle ring has an annular funnel-shaped structure, and the lower part of the baffle ring has a ferrule structure; a wrapping gap is reserved on the outer circumference of the baffle ring wrapped in the stuffing box; a sleeving gap is reserved on the excircle of a ferrule sleeved on the pump shaft; a cold acid liquor inlet is formed above an annular funnel; and cold acid liquoroverflows from the annular funnel on the upper part of the baffle ring and flows out of the sleeving gap through the wrapping gap. The acid pump is mainly applied to a low-temperature recovery systemof acid; acidic gas does not escape during work, so that the acid pump has high sealing property; meanwhile, the acid pump has good lubricating and cooling effects, so that work safety and service life are ensured.

Description

technical field [0001] The invention relates to an industrial pump, in particular to a special acid pump mainly used in an acid low temperature recovery system. Background technique [0002] At present, the shaft sealing device of the acid pump basically adopts packing seal, and for the special acid pump of the acid low temperature recovery system, the temperature of the acid is generally more than 200 degrees, so the volatility of the acid is particularly strong, and the ordinary packing seal cannot be very It is best to prevent the escape of acid gas, and the working environment is harsh. At the same time, due to the lack of good lubrication and cooling, the heat of the acid is transmitted through the pump shaft, which makes the working temperature of the motor and bearings high, which directly affects the working safety and service life of the acid pump. Contents of the invention [0003] In view of the problems existing in the current known technologies, the technical ...
