The invention provides a split centrifugal pump seal box which comprises a seal box panel, a shaft sleeve, a seal box body and a seal box cover. The bottom of the seal box body is fixedly mounted on the seal box panel, the shape and the size of a spigot of the seal box cover are as same as those of a spigot in the top of the seal box body, the seal box cover is detachably connected on the spigot in the top of the seal box body, the shaft sleeve sequentially penetrates the seal box cover, the seal box body and the seal box panel from top to bottom, an air flow meter is arranged at the joint between the seal box cover and the seal box body and connected with a processor through a line, and the processor is connected with a warning light through a line. Compared with the prior art, the split centrifugal pump seal box with a separable split structure is convenient to install and maintain and high in practicability, replacement of the whole seal box is omitted when accessories are replaced, maintenance cost is saved, the seal box is less in machining allowance as compared with a casting seal box, machining qualification rate is high, overall operation cost can be reduced, and air leakage can be monitored in real time.
Description
technical field [0001] The invention mainly relates to the field of sealing boxes, in particular to a split type centrifugal pump sealing box. Background technique [0002] At present, the structure of the sealing box of the centrifugal pump is integral, which requires integral casting, which is prone to casting defects, low yield and large machining allowance. When replacing parts, the whole set must be replaced, and the maintenance cost is high; a detachable, installation and maintenance Convenience, no need to replace the whole set when replacing accessories, cost-saving split centrifugal pump sealing box, moreover, the sealing box of the prior art is prone to air leakage, which affects the sealing effect, so it is necessary to solve these problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a split type centrifugal pump sealing box. The sealing box has a separable split structure, which is convenient for...
