Explosion-proof technology features (core) of explosion-proof centrifuges
• Inert gas to prevent explosion
The inner chamber and the rotating shaft of the centrifuge are filled with inert gas, generally nitrogen, together with our advanced pressure balance technology (inert gas control system and pressure balance system) to ensure that “the centrifuge chamber does not leak, and the outside air does not enter the chamber.”
• Rotating shaft sealing technology
[ZK Separation] According to the material medium and the explosion-proof grade, different sealing forms are selected, such as carbon ring, skeleton oil seal, metal seal ring, and dry gas seal, etc., which can be used individually or in combination. The pressure at the position of the rotating shaft can be controlled at 5 KPa~0.3 MPa.
★ Combination of multiple electrical control and mechanical protection means
o Equipment nitrogen filling and automatic comparison of pressure of each pipeline and position. The centrifuge can be started after self-test is passed;
o High and low nitrogen pressure protection, effective measures such as sound and light alarm and delay shutdown;
o Oxygen meter (optional), which can monitor the oxygen inside the centrifuge in real time to realize the interlocking protection of start and stop;
o Double-seal ring protection for static sealing;
