Leakproof handle for pump equipment
Pump equipment is one of the common mechanical equipment in industrial production and daily life, which is widely used in chemical industry, petroleum, metallurgy, electric power, pharmacy and other industries. In the use of pump equipment, the leakage problem not only affects its normal operation and work efficiency, but also may pollute the environment and even cause safety accidents. Therefore, it is particularly important to strengthen the sealing performance of pump equipment, and the "leak-proof handle" technology is an effective means to solve this problem.
First, the design principle of "leak-proof handle"
1. Mechanical seal: The dynamic ring and the static ring are made of high-performance materials. Under the action of axial compression force, the dynamic ring and the static ring are closely attached to form one or more sealing end faces, thus achieving the purpose of preventing medium leakage.
2. Packing sealing: The packing (a soft material composed of graphite and fiber) is fastened inside the pump body by gland, and the sealing effect is achieved by using its elastic deformation after being compressed.
3. Dry gas seal: It is suitable for gas conveying system under high pressure. Two parallel rotating surfaces with special groove structure are mainly used to generate heat by mutual contact and friction, and this heat energy is used to heat the surrounding gas to maintain a stable micro-positive pressure state, thus preventing the fluid from entering the gap and leaking.
Second, the characteristics and advantages of "leak-proof handle"
1. High reliability: "Leak-proof handle" usually uses high-quality metal materials as the basic component, which has strong corrosion resistance and wear resistance; At the same time, the sealing element made by precision machining can effectively avoid product failures caused by material defects or manufacturing errors.
2. Easy maintenance: Compared with the traditional packing or rubber ring pump shaft seal, the "leak-proof handle" has a simpler and more convenient operation process-just check and adjust the position relationship of related parts regularly to complete the maintenance work; In addition, because the device itself is compact and light, it is more convenient and convenient to disassemble and replace.
3. Wide application range: it can play a stable role in both low-pressure and ultra-high-pressure environments; It can be used not only in the transmission pipelines of various liquid media such as clean water and sewage, but also in the treatment places of various gas media such as steam and air.
4. Economical and efficient: Although the initial investment cost is higher, in the long run, it can greatly reduce the expenses generated by frequent maintenance in the later period; In addition, its service life is long (generally up to tens of thousands of hours), so the overall economic benefit is very significant.
III. Concluding remarks
With the continuous improvement of scientific and technological level and people's increasing awareness of environmental protection, the requirements for pump products, especially the safety protection measures involved, will be higher and higher in the future. As an innovative solution, "anti-leakage handle" has been widely recognized by the industry and gradually popularized. I believe it will certainly promote the progress of the whole industry and bring more benefits to human society!
