Desulfurization pump is a common industrial device. Now let us learn the matters needing attention when using desulfurization pump.

    1.The fabrication of bearing assembly

Install the two angular contact ball bearings back to back in the bearing box, and install the bearing box on the shaft shoulder near the shaft end of the pump coupling. Install the oil baffle disc and cylindrical roller bearing in order at the other end of the shaft. Tighten the bearing with round nuts at both ends of the shaft, and then pass the shaft into the bearing body. Set the bearing box and bearing gland respectively, and cover them with dustproof disc, water retaining ring, round nut and shaft sleeve. Finally, install these parts on the bracket.

    2.The fabrication of packing shaft seal assembly:

The shaft seal assembly consists of stuffing box, shaft sleeve, packing ring, packing and packing gland. The filler is made of carbon fiber which is wear-resistant and corrosion-resistant.

    3.Partial assembly of pump head:

    Firstly, install the back pump casing into the stuffing box and fasten it to the bracket. Install the “O” ring and auxiliary impeller (or impeller retainer ring) on the shaft, install the rear cover shell on the rear pump casing, and then fasten the impeller on the shaft. After that, put the “O” ring and volute on the rear cover shell, and install the “O” ring on the front cover shell, and install front cover shell on the volute. Finally, assemble the front pump casing with the pump casing and tighten the bolt. Please note that all the “O” rings should be placed correctly and compressed during fabrication.
