Common Faults And Causes Of Shanghai Stainless Steel High Pressure Reactor

- Jul 20, 2019-

The material of Shanghai stainless steel autoclave is mainly made of 1cr18Ni10Ti stainless steel, and can be made of titanium (TA2), nickel (Ni6) and composite steel according to different media requirements. The structure of the kettle body has flat cover, convex cover and manhole. The closed reaction kettle body and the opening on the kettle lid can be designed according to the user's requirements; the heating method includes jacket steam, jacket hot oil electric heating and the like for the user to order when arbitrarily selected. For the inner surface of the kettle with polishing requirements, the above mirror polishing level can be achieved, and the high-viscosity material can be processed into a conical bottom for easy discharging and cleaning. So usually we will encounter some small problems in our use, which will affect the progress of our work. How can we solve the problem when we encounter the failure? Let’s talk to everyone today.

Common Faults and Causes of Shanghai Stainless Steel High Pressure Reactor

1. Fault phenomenon: A leak occurs at the sealing surface. The cause of the malfunction: the screw thread is loose; the sealing surface is damaged. Remedy: Re-tighten the screw; re-polish the polished sealing surface.

2. Fault phenomenon: A leak occurs at the valve. Cause of failure: Damage to the valve stem (needle) and valve port sealing surface. Remedy: Repair, replace the valve stem (needle), valve port.

3. Fault phenomenon: the outer magnetic steel rotates, the inner magnetic steel does not rotate, and the motor current decreases. The cause of the failure: the temperature rise in the kettle is too high, the cooling cycle is not smooth, and the inner magnetic steel is demagnetized due to high temperature. In the hydrogenation reaction, the inner magnetic steel sleeve has cracks and the inner magnetic steel expands. Remedy: Inform the supplier to replace the inner magnetic steel.

4. Fault phenomenon: there is friction noise in the magnetic coupling actuator. The cause of the failure: the bushing and the bearing are worn out, the clearance is too large, and the inner magnetic steel is bouncing. Remedy: Contact the supplier to replace the bearing and bushing.
