Abstract
The utility model discloses a modified split-type packing seal structure which comprises a lower gland which is installed on a pump body. An upper gland is installed on the lower gland through a bolt at intervals. The upper gland and the lower gland are both semi-annular split type structures. A hold-sown ring, a packing ring and an adjusting ring are sequentially sleeved in a sealing annular space formed by the upper glands, the lower glands and a pump shaft from outside to inside, wherein the hold-sown ring, a packing ring and an adjusting ring are all in a semi-annular split type structure. The modified split-type packing seal structure is simple in structure, convenient to disassemble and assemble, and capable of greatly shortening replacement time of the seal structure.
Description
Technical field
The utility model relates to a kind of improved split type packing seal structure.
Background technique
Ethylene plant's vinyl benzene still class process units: wherein pressure is low, and temperature is high, spends or stop lower than 200 when temperature to surpass 3 hours, and medium will be condensed in and cause quality of product defective in still.Due to 260 ℃ of pump body temperature, diameter of axle Φ 150mm, the transmission device complexity is not quick detachable, and former sealing life cycle is short.
Summary of the invention
The purpose of this utility model is to provide a kind of improved split type packing seal structure, can just can dismantle and install packing seal in the situation that do not disassemble motor and coupling, shortens dead time, makes to change to be sealed in setting time and to complete.
The purpose of this utility model is to realize like this, a kind of improved split type packing seal structure, comprise the lower cover that is arranged on the pump housing, by the bolt interval, a upper press cover is installed on lower cover, upper lower cover is semicircle annular split type structure, putting hold-down ring, packing ring and adjustment ring by outer toward the interior installing of engage sleeves successively in sealing annular space between upper lower cover and pump shaft, said hold-down ring, packing ring and adjustment ring are semicircle annular split type structure.
The utility model is simple in structure, and easy accessibility can be in the situation that do not disassemble motor and coupling; just can dismantle and install packing seal; shorten dead time, make replacing be sealed in setting time and complete, can greatly shorten the replacing time of sealing configuration.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
