The invention discloses an integral packaging type mechanical seal device. The integral packaging type mechanical seal device comprises a mechanical shaft, movable rings and fixed rings; the movable rings comprise the first movable ring and the second movable ring, the fixed rings comprise the first fixed ring and the second fixed ring, the device further comprises movable ring shaft casing pipes,a gland and a mechanical seal fixing
flange, the movable ring shaft casing pipes comprise the first movable ring shaft casing
pipe and the second movable ring shaft casing
pipe, the first movable ring shaft casing
pipe is arranged on the mechanical shaft and between the movable rings and the fixed rings, the two movable rings are arranged at the two ends, the fixed rings are arranged between thetwo movable rings, the second movable ring shaft casing pipe is adjacent to the second movable ring, and the second movable ring shaft casing pipe is arranged outside the first movable ring shaft casing pipe; the first fixed ring and the second fixed ring are sleeved with the gland with a water inlet and a water outlet, and the gland is connected with the mechanical seal fixing
flange; and a sealcavity is formed among the gland, the movable rings, the fixed rings and the movable ring shaft casing pipes. The integral packaging type mechanical seal device is compact in structure, easy to
mount,convenient to use, good in
dynamic balance, durable, capable of being used for sealing of the
solid and liquid particle mixture working condition and high in belt pressing seal durability.
