The medium transported by pumps in chemical plants generally has high risk characteristics of toxicity, flammability, and explosiveness. Therefore, once a leak occurs, it may not only cause incalculable economic losses and environmental pollution, but more importantly, it may also cause casualties. In order to avoid such incidents, the relevant mechanical equipment used in the industry has high sealing performance. At present, most lathe shaft seals in chemical enterprises use packing seals and mechanical seals.

From the perspective of the structural form of mechanical seals, Dongheng Seal mainly has two types: double end mechanical seals and single end mechanical seals. Through sealing, it can play a positive role. In the transportation of flammable and explosive media and toxic media, it can ensure overall non leakage and help reduce mechanical losses, effectively improving the overall efficiency of transportation.

The common symptoms of mechanical seal failure in chemical equipment can be summarized as: continuous leakage of mechanical equipment, screams during operation of chemical equipment, etc. Secondly, when chemical equipment is running, graphite dust will appear on the outer side of its sealing surface, which will clump together. On the other hand, when chemical equipment is in operation, the sealing part of the equipment will emit a burst sound, which may also indicate the mechanical seal failure of the chemical equipment. Meanwhile, if the pump and shaft continue to vibrate, the service life of the seal will be shorter, which may be due to the mechanical seal failure of chemical equipment. When the above situation occurs in chemical equipment, relevant technical personnel should inspect the mechanical seal to further determine whether it is a fault in the mechanical seal of the chemical equipment and identify the cause of the fault. No leakage is the eternal pursuit of chemical machinery equipment, which has promoted the good development of magnetic pumps and shielded pumps. However, there is still a long way to go to truly achieve no leakage. Mechanical seal is an advanced dynamic sealing product that is mainly sealed by a pair of smooth surfaces and a liquid film with the help of medium pressure and spring force. Compared with packing seals, mechanical seals have a more prominent effect, no wear, longer service life, and less specific power consumption, making them widely used in dynamic sealing positions. Especially in places with poor working environments, such as high temperature, high pressure, low temperature, low pressure, toxic, flammable, explosive, and corrosive. Ordinary sealing cannot achieve this effect. We need to contact China Dongheng Seals.
