Water pump mechanical seal products industry market
Mechanical seal is small products, but its level of technical performance and quality, to improve and the revitalization of the equipment industry in China is very important. As machinery industry supporting industry, mechanical seals must host as the core, with the influence of accessories technology innovation and promote the modernization level of the host. According to China's flood control and drainage, chemical mechanical plastic truck seals of large water conservancy engineering applications such as water pollution governance requirements, jiangsu asia-pacific pump industry group undertook the national ministry of water resources of large power of 10000 kw submersible pump research topic. The special pump for the mechanical seal device for the first time 12000 hours service life requirements, the technical indexes and performance must reach the international first-class level. Lianyungang HuaQing company with more than a month of time, only then developed the domestic unique special machine as scheduled. Confirmed by the national water conservancy department organization, a very large pump drainage performance and mechanical sealing device of the international most advanced level of similar products. HuaQing company in recent years around the pump machine to carry out technological innovation, have developed to adapt to Huang Hegao sand slurry pump seal water delivery; To adapt to the ultra high temperature operation under the environment of metal corrugated pipe pump machine seal; To adapt to the high-rise construction of high pressure water conveyance pipeline pump seal; To adapt to the high resistance to mineral scale crystal mine pump container security seals; To meet the needs of big oil, chemical industry, used for fuel pump mechanical plastic padlock security seals and inflammable, explosive fluid conveying high pressure chemical pump seal and so on dozens of water pump machine varieties. As HuaQing machine sealing structure of innovation and product application field expands unceasingly, some local host plant wide and large amount of supporting the market, constantly armed with HuaQing developed all kinds of special machine sealing new equipment, transforming the old products, to replace imported products. Recently, the hainan MiPu waterworks in Sweden axial flow pump, ningbo, introduced in the wastewater treatment plant sewage pump in Japan, nanjing jiangxin island sewage treatment works to introduce German high quality water pump, sewage pump, etc are developed to HuaQing mechanical seal multi-function, high performance machine sealing instead of international brand-name products; Jiangsu asia-pacific hydraulic, shandong bo pump technology co., guangdong foshan pump industry, zhejiang feng ball pump industry enterprises of national brand products, equipped HuaQing machine, exported to Europe, America, southeast Asia, dozens of countries. Just a few short years, HuaQing company supporting export machine sealing ChuangHuiE accumulative total more than $1200, in line with international standards for GuoChanJi sealing abroad creates opportunities.
In one or two end face appeared gap, this phenomenon shows that the two face is too big, apart when two ends together tightly, can produce a gap. The common cause of end face separation is flashing import mechanical seal medium. For example, water, especially in the hot water system or contain the condensate liquid, water evaporation, and separated the two ends. Pump cavitation and seal block also may cause the cause of the gap is to make the container security seals. In this case, it is not caused by vibration and coupling the champions league, because it is not enough to make face generation gap. The lower end face temperature is a common way to prevent damage of medium evaporation end sharply. At the same time, USES the materials with good thermal conductivity is also good, such as with nickel-based carbide and leaching of copper and graphite group, in addition, the balance type mechanical cable tie wraps, or the use of special corrosion resistant mechanical seal gland from external injection liquid cooling, or directly to the cooling chamber seal, and so on, is very effective to reduce the temperature of the seal face. Failure of mechanical seal, friction pair end surface radial cracks are very fine, radial cracks and blisters or mark, or even cracked. This is caused by sealing overheating, especially ceramic, carbide seal face prone to this type of injury. Poor lubricity of medium, high overload, high operating temperature, velocity, improper matching material combination, etc., including any kind of factor, or is the superposition of several factors, can produce excessive friction heat, if frictional heat can't send out in time, will generate dyeing mechanical seal of hot crack, resulting in excessive wear and high leakage. Solve the overheating of the seal, in addition to change the face area, reduce the load, also can use static type Fixed Length plastic seal and diversion of forced cooling circulating fluid sealing surface, or on the seal face hydrodynamic trough to be solved. Friction on the face, there are many tiny hot spots and discolouration of the isolation zone, suggesting that seals under high pressure and thermal distortion under the influence of deformation. For the thermal deformation of the face, the general method of calculation is not allowed, should use the finite element method to calculate, in order to improve the design of the sealing ring.
Calls for shippers to take various measures to reinforce sealing seals container seals to prevent theft. When packing the goods should be considered theft, in addition to conventional sealing seals container seals, but also in the title box nut at the door seals container seals, seal affixed junction box wall, cargo up to the port, should pay attention to sealing is intact, whether there are aspects of replacement checks to ensure cargo security. vehicle cargo seals urge the shipper, the Employer to strengthen monitoring of transport vehicles. Further strengthen the shipper, the Employer's legal awareness and risk awareness, seals container seals may require truck drivers transport routes in the contract of carriage, asked the driver to travel in accordance with the provisions of the route, and transport vehicle assembly GPS satellite monitoring system, the effective protection of vehicle trips management control. For transportation routes long or expensive cargo transport truck container seals seals simultaneously with guard personnel. With related units to establish security cooperation mechanisms.
mostly to middle and low commodity-based private enterprises, but the accumulation of funds agility, using the country has the skills set of experienced personnel , skill levels progress rapidly, its product quality, variety and serve to continue moving forward in the contest; foreign company to senior commodity-based, skill level and that appropriate for domestic joint ventures, wholly-owned companies need advanced host and supply supporting key projects . Indicative Seals along with the rapid expansion of China's economy, with a selection of various types of mechanical hydraulic, pneumatic complete transmission and increasing manipulation skills needed to seal the growing forward. China launched agile hydrodynamic goods malls, in addition to the United States, Europe, Japan, launched in the country ranked in first. Valqua Chinese imports also increased, and the mall expansion potential. Expand the potential of infinite outlook followed industrialization and automation level of progress, need for mechanical support with a lot of high performance and high reliability of hydraulic pneumatic and sealing components. Began to estimates, the state's construction of infrastructure and basic industries booming expansion; addition to the Three Gorges, water, gas, electric power, and the Qinghai-Tibet railway construction project of the century, there are a large number of large coal mines, oil fields, outdoor iron mine key projects, power plants, airports, ports, high-speed railway, highway, etc., as well as many cities, such as construction and residential construction. To this end, earthwork handling the workload continues to add, plus logistics modernization Cargo unfolds, as well as new technologies, new skills and new materials to use, will enable the domestic construction machinery requirements for long-term increasing trend.
