The invention provides a working table for installing a mechanical seal of a water pump and relates to the technical field of water pump
machining tools. The working table comprises a working table body, a supporting frame, a supporting arm, a mounting base, a sliding sleeve, a slide bar, a support, a hand wheel shaft, a hand wheel, an
assembly port, a lifting rack, a gear, a baffle and a reset spring. The working table is characterized in that an annular pump cover base is arranged at the position, opposite to the slide bar, of the working table body, the lower end of the slide bar is provided with a sealing ring pressing plate, a buffer pressure pad is arranged on the sealing ring pressing plate, a vertical
threaded rod is formed in the upper portion of the mounting base, a
stroke adjusting bolt is arranged in the threaded hole, and the upper end of the slide bar is provided with a limiting stop dog matched with the
stroke adjusting bolt. In the using process, a pump cover is placed on the pump cover base, a static ring of the mechanical seal is placed into a mounting groove of the pump cover, the
stroke of the sealing ring pressing plate is adjusted, and then the hand wheel is rotated to drive the sealing ring pressing plate to press the static ring of the mechanical seal into the mounting groove of the pump cover. The working table has the advantages of being simple in structure, convenient to use, high in assembling accuracy, assembling speed and assembling quality, good in sealing performance and long in service life.
