The double-layer glass reactor can be connected with low-temperature coolant circulating pump, high-low temperature integrated machine, closed refrigeration and heating circulating device, constant temperature circulating device, circulating cooler, diaphragm vacuum pump, multi-purpose vacuum pump for circulating water and other equipment.
In general, the double-layer glass reactor shall be subject to air tightness test before leaving the factory, but the air tightness performance will decline after the equipment operates for a period of time. In order to prevent leakage during the reaction test, it is necessary to carry out air tightness test regularly. Airtightness is an important performance index of glass reactor. Because the reaction test of chemicals containing harmful chemicals is often carried out in the reactor, the consequences of leakage accidents are very serious. Therefore, if there is no sealing inspection, the reactor cannot work stably for a long time.
Three methods to detect the sealing of double glass reactor:
1、 Temperature test, pressure test and air tightness test are adopted. The test medium can be air and nitrogen. The ideal is inert gas. Oxygen or other gases are prohibited.
2、 The pressure shall be measured by means of temperature rise and pressure rise. The process of temperature rise and pressure rise must be carried out slowly. The heating speed shall not exceed per houreightyDegrees. During the pressure test, connect the inlet valve of the compressor or high-pressure pump to the glass reactor. Be sure to step up the pressure in several times, taking the working pressure as the interval, and stay at each rising gear5Minutes and stay when it rises to the test pressurethirtyMinutes, observe the sealing condition and test the pressure at100-105%between.
3、 If air leakage is found during the test in the double-layer glass reactor, the pressure shall be reduced first, and then the nuts and joints shall be properly tightened. It is strictly prohibited to tighten under high pressure.
