Professional equipment to suppress "water hammer",SME industry check valve

Generally, when the inner wall of the pipeline is smooth and the water flow is free to move, if the opened valve is suddenly closed, it will cause the instantaneous impact pressure of the water flow on the valve under the action of inertia, commonly known as the "water hammer phenomenon". This is also the true face of the strange noise at night in the residential area. When the valve is closed, the pressure generated by the pipeline is too high, which can easily cause the water pipe to burst, which is called "positive water hammer"; on the contrary, the pressure generated when the valve is opened is too low, which will cause the pipeline to collapse, which is called "negative water hammer." The common point is that they will all have a strong destructive effect on the pipeline, and the valves and fixtures themselves will not be spared. Another form of water hammer is called "steam water hammer",

Jackhammer's Special Hose Minsup Coupling From SME

In addition to liquid media in the industrial field, air media is also one of the commonly used energy sources. As a common energy source, the air is highly efficient, clean, cheap and easy to adjust, and it is widely used in many industries. In fact, the jackhammer, which is used for stone mining on daily construction sites, ground drilling and breaking concrete rock formations, is a common tool that uses compressed air as power. First of all, under normal circumstances, the surrounding air is at atmospheric pressure of 14.7 pounds per square inch. When used as an energy source, the air will be compressed and delivered to the jackhammer through an air hose. The pressure at this time will be several times higher than the atmospheric pressure. At the same time, the air inside the jackhammer is released with explosive force and returns to normal atmospheric pressure. This is how jackhammer works. The jackhammer uses an explosive instantaneous force, and then uses an axial thrust to drill

Drop test! SME demonstrates the quality assurance of KLAW Dry Break Couplings

As a high-end product in the chemical industry - Dry Break Coupling. The high-efficiency and versatile features can even be widely used in low-temperature environments. It is superior to traditional flange connection methods (link " Deliver safer and more efficient solutions for LPG ") and has been consistently recognized by users. The simple operation method and the "Zero Spillage" feature greatly improve the safety of many chemical industries in some hazardous environments. The high-end features can indeed leave a very deep impression, but if the price deviation is too large, for some customers, the dry break couplings are still a more luxurious choice. It is true that as a high-end product, dry joints have their own technical content and internal structure that make them outstanding in functionality, but this does not mean that all customers can be convinced to make dry-break couplings the best choice. For example, th

SME high recommend the representative product from KLAW - Breakaway Coupling

Breakaway Coupling  is a high-end safety valve commonly used in the chemical industry. Compared with the function of dry joints, the use of Breakaway Coupling  is more profound. As an emergency release device, the  Breakaway Coupling  is usually set at the weak connection point of the entire transmission link. When the set conditions are reached, the pipeline is disconnected and the valve is instantly closed, while the intermediate medium is self-sealed in the pipeline. Minimal dripping and relatively small pressure loss can effectively prevent leakage accidents caused by accidental rupture of pipelines. Applicable fields include ship-to-shore unloading, road and railway tank loading and unloading, and other fixed and mobile fluid storage devices, such as crane pipes, The connection between the fluid transport arm and the transport carrier. Under normal circumstances, when perfo

SME shares operational considerations for LNG stations

Nowadays, natural gas, which ordinary people usually use for cooking and heating, is also used as vehicle fuel. Compared with diesel, natural gas combustion produces very little pollution and does not produce any smell or smoke. Another advantage is that vehicles that use natural gas as fuel produce three times less noise than those that use diesel, so the vehicle can drive in urban areas without noise pollution. When natural gas is liquefied as fuel, it is commonly referred to as liquefied natural gas (LNG) . Specifically, it is obtained by condensation at -162°C. Compared with the gaseous state, the liquid volume is reduced by about 600 times. In other words, fuel tanks with highly enriched natural gas can provide trucks with a distance of more than 1,000 kilometres . When the vehicle is running, natural gas is injected into the engine in a gaseous state and converted into the power required by the

Jackhammer hose mate minsup claw couplings from SME

The「 European Minsup claw coupling 」is a standard connection used for water and gas transmission and air pressure hoses from SME Industrial. It can be used for air compression pipes for small jackhammers, or for large equipment such as ore mining and rock drilling. Use pipes, etc., not for steam pipes. This series of joints has a uniform claw distance, which eliminates the trouble of checking the joint diameter when connecting air pressure pipes of various diameters. It can be matched with SME standard saddle hose clamp or conventional carbon steel crimping assembly.

The "South-to-North Water Diversion" project promoted by the China government in 2012 is a basic project to optimize the allocation of water resources and promote coordinated regional development. It is a strategic project with the largest investment and the most extensive coverage since the founding of China. South-to-North Water Diversion In the fact , the water supply area on the east line of China was densely populated, concentrated in cities, convenient in transportation, and rich in resources. It was an important energy and chemical production base and a major production area for agricultural products such as grain. The potential for economic growth is huge, but the contradiction between water supply and demand has become increasingly prominent. Water shortage has restricted economic and social developmen
