Description
Technical Field
The utility model belongs to the technical field of the machine seals technique and specifically relates to a silicon tetrafluoride reactor is with machine seal.
Background
The mechanical seal is a full name mechanical seal, and is commonly known as the mechanical seal in the industry. The sealing device is used for solving the problem of sealing between a rotating shaft and a machine body. The machine seal commonly used in the market at present is a double-end machine seal. The spring is arranged at the bottom of the mechanical seal, and the mechanical seal leakage often occurs due to the fact that the material silicon dioxide dust is large. The main reason for the leakage of the price machine seal is that the spring in the machine seal is adhered by dust and loses elasticity. The mechanical seal is prone to leakage. The mechanical seal movable ring and the stirring shaft are sealed by a tetrafluoro trapezoid ring, and the sealing effect is poor. The fit clearance between the mechanical seal and the shaft is small, the adjustment is difficult during installation, the mechanical seal is easy to break, and the labor intensity of maintenance workers is high. The mechanical seal has short service life.
