How to prevent accidents in Suzhou dense bus duct

Today, I will talk to you about how to prevent accidents in Suzhou dense bus ducts. Below, I will introduce you to Suzhou dense bus ducts. Everyone knows that to choose a product or service, we need to understand the processing, service, quality and other aspects of the intensive bus duct in Suzhou.

After many people have used Suzhou dense bus duct for a period of time, they will find that some Suzhou dense bus duct will encounter the sealing ring breakage, which is very dangerous. So, is there any way we can prevent this kind of accident from happening? Of course the answer is yes, let's find out below!

The cracking of the seal ring of Suzhou dense busway is one of the common phenomena of early failure of mechanical seal. The graphite static ring is mainly broken, and the ceramic and tungsten carbide moving ring are mainly sealed by cracks and deformation of the end face. The graphite ring of the dense bus duct in Suzhou was broken and the seal was severely leaked. The sealing water pressure cannot be guaranteed to be greater than the medium pressure. Although there are cracks in the moving ring of the dense busway in Suzhou, which causes an increase in leakage, it can maintain operation in most cases. There are many reasons for the broken graphite ring, mainly as follows.

(1) The rubber sealing ring or PTFE V-ring is too tightly matched with the graphite ring and the static ring seat, and the graphite is squeezed and broken under dynamic conditions.

(2) The impact is too heavy when installing the seal chamber and pump body, or the pump body seal chamber is seriously inclined.

(3) The swing and string amount of the axis exceed the specified value.

(4) The sealing water is interrupted, the friction pair is dry friction, the temperature rise is too high, the sealing ring is thermally cracked, and the sealing water is suddenly sent, causing the sealing ring to shrink and crack.

The main causes of cracks in the moving ring of the dense busway in Suzhou are as follows:

(1) The cemented carbide moving ring has a relatively large stress. When the moving ring is running, cracks appear under the combined action of external and internal forces. These cracks are dense micro cracks diverging in the radial direction.

(2) Temperature influence: Non-metallic materials are used as the sealing ring (such as ceramics, WC). Due to poor heat conduction, the temperature distribution in the ring is extremely uneven. Even under normal conditions, the temperature difference may reach several hundred degrees due to the temperature difference. , And then produce thermal deformation and cause thermal stress. When the thermal stress reaches a certain level, it causes the stress to exceed the strength limit of the material. At this time, the sealing ring of brittle material often has surface cracks, which in turn causes the friction and wear of the sealing surface to intensify and fail. Due to the thermal deformation, the gap of the bonded sealing surface will be distorted, which will increase the leakage.

When the end face of the moving ring is made of cemented carbide, since the thermal expansion coefficients of these materials are small, and the thermal expansion coefficient of the base material is quite different (the thermal expansion coefficient of stainless steel is 3 to 4 times higher than that of cemented carbide), so when the sealing temperature When the rise exceeds a certain value, it will cause the deformation or cracks of the surfacing cemented carbide sealing ring.

The effective measures taken by the Suzhou intensive busway manufacturer to solve the dynamic and static breakage and deformation, in addition to strictly controlling the quality of spare parts processing, careful installation and maintenance, and strengthening operation management, it is an important measure to ensure that the sealing end face can be adequately lubricated and cooled. However, in the actual operation of the dense busway in Suzhou, sufficient lubrication and cooling cannot be guaranteed at all times. Fluctuations, interruptions of the sealing water pressure and misoperation of workers will cause the seal to lose sufficient lubrication and cooling.

The above is the small coup that the editor brings to you today to prevent accidents in the dense bus duct in Suzhou. In normal times, we must not be afraid of troubles and ignore what we said above. Once an accident occurs in the dense bus duct in Suzhou, really It is a particularly tricky thing, everyone must not take it lightly!

The above is how to prevent accidents in the dense bus duct in Suzhou, which is provided by Jiangsu Xusheng Electrical Equipment Co., Ltd. The company has always followed the standardized management and the production and service policy of putting quality first, providing customers with assured and satisfactory products and services of Suzhou intensive bus ducts.
