Problems solved by technology
[0002] In petrochemical production, in order to ensure production safety and ecological environment, mechanical seals are often used for rotating equipment conveying various fluid media to achieve this purpose, especially when conveying toxic, harmful, flammable and explosive media. It is necessary to choose a safe and reliable mechanical seal, but the actual situation is that on such equipment, users often use double-end mechanical seals with sealed oil systems. It seems safe and reliable, but it is actually not the case, especially for high-temperature oil pumps. Because the oil seal will also cause oil leakage and cut-off, especially when the equipment is evacuated and vibrated, this situation is more likely to happen, which is undoubtedly a hidden danger for safe production and environmental protection

Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawing:
[0022] Such as figure 1 As shown, the sealing sleeve 5 and the inner cavity of the gland 9 are tightly connected by threads to form a cylinder with the gland 9, and then, the gland end is vertically placed on the table top.
[0023] Then insert the front end static ring 6 coated with grease on the end face annular groove M into the middle inner ring of the sealing sleeve 5 so that the back shoulder can withstand it.
[0024] Then, screw the moving ring anti-rotation screw 19 and install the T-shaped moving ring 21 equipped with the front wear-resistant ring 22 on the shaft sleeve 15 equipped with the moving ring sealing ring 20 and make the moving ring anti-rotation screw 19 Insert it into the anti-rotation groove opened on the shaft sleeve, then insert the whole assembly into the cylinder body with gland and stick the front end wear-resistant ring 22 and the end face of t...
