Expansion control method of glass lined reaction tank

The glass lined reaction tank is often exposed to high temperature when it is used. In order to use it safely, we should properly understand the expansion control, so as to ensure the safety of the equipment
1. It is difficult to control the clearance between piston skirt and cylinder liner due to the different working temperature of each part of glass lined reaction tank and the expansion characteristics of aluminum alloy piston and cast iron cylinder liner. Effective skirt shape can not overcome the different expansion rate between piston and cylinder. In addition, the small clearance determined under heavy load of the engine will also cause excessive clearance under partial load, resulting in cylinder knocking noise.
2. In order to control the clearance between the piston skirt and the pin seat, a pair of steel plates are symmetrically embedded between the piston skirt and the pin seat, and the steel plates are properly extended around the skirt of the glass lined reaction tank. The steel sheet and the surrounding materials form a bimetallic sheet, When heated, it shrinks along the axis of piston pin. This kind of piston has no heat insulation groove in the transition section between the ring groove and the skirt, and the heat flow can be smoothly transmitted to the skirt. Therefore, the temperature of a ring groove area is lower than that of the slotted piston, and the strength is relatively high. The thermal expansion is controlled by inserting steel sheet or steel ring in skirt.
The above is the introduction of the expansion control method of glass lined reaction tank. It is inevitable that thermal expansion will occur during heating operation. We must pay attention to the protection of the equipment to prevent the phenomenon of bursting in the process of use.
