LSLZ Dry Running Mechanical Seal

1. The proposed structure is suitable for a single-face, integrated mechanical seal, utilizing a shaft sleeve for clamping and fixation onto the shaft, thereby eliminating potential interference during installation.

2. Incorporated within this structure is a large spring, adaptable to any spiral direction, exhibiting superior anti-clogging capabilities. Furthermore, the friction components, designed as a hard-to-hard configuration, offer remarkable abrasion resistance.

3. This mechanical seal is tailored for vertical submerged desulfurization pumps, and can be equipped with a leakage alarm and an automatic shutdown protective device. The unique structure ensures reliable sealing performance.

4. When utilizing the mechanical seal for desulfurizing applications, it is imperative to consider the issue of chloride ion corrosion resistance of the seal material.

1. Prior to installation, it is imperative to lubricate the inner hole of the shaft sleeve and O-ring to ensure smooth installation.

2. Following confirmation of the mechanical seal installation, the rubber O-ring 1 and snap ring 2 must be removed prior to machine activation.

3. To prevent pulp accumulation around the sealing surface and subsequent mechanical seal failure, it is essential to maintain the sealing cavity and tailboard in an open configuration. This mechanical seal lacks both external cooling water and internal flushing water, relying solely on pulp for seal surface lubrication. Therefore, it is strictly prohibited to operate the pump with any evacuation or pulp-free conditions within the seal chamber (idle running is not permitted).
