  • NOK Original Seal from WONEPART,NOK seals are important mechanical parts that prevent the lubricant, water, liquid chemicals and gases on the machine from leaking out of the gap, and at the same time prevent sand and dust from entering from the outside.

  • The step seal is composed of a rubber O-ring and a polytetrafluoroethylene ring. The material is PTFE + NBR. In special cases, the rubber elastomer nitrile rubber NBR uses fluorine rubber FKM. It can be divided into step seal for hole and grid ring for shaft, but its sealing effect is the same. According to its own deformation, it will produce higher initial contact stress on the sealing surface and prevent the leakage of pressureless liquid. When the hydraulic cylinder is working, the pressure liquid passes through the elastic deformation of the O-shaped sealing ring to squeeze the square sealing ring to the greatest extent, making it close to the sealing surface, which produces a higher additional contact stress that increases with the pressure of the pressure liquid. Together with the initial contact stress, the leakage of pressure liquid is prevented.

  • What is the gap between the oil seal and the mechanical seal? The key function of the sealing ring is to protect the grease, so that the components that must be lubricated in the transmission components and the mechanical energy components protect each other. The mechanical seal refers to the device that processes the sealing relationship between the driving force cardiomyocytes and the arc. The skeleton oil seal is a category typical of the seal ring, which means a commodity. Usually, when talking about the seal ring, these "heavy-weight" skeleton oil seals are always thought of. In short, the skeleton diagram refers to the key construction of the supporting points and determination of the sealing ring, which can improve the actual sealing effect of the sealing ring, so that the sealing ring can maintain the appearance and excellent supporting force. According to the structure of the seal ring, the skeleton oil seal can be divided into a single-lip skeleton oil seal and a lip skeleton oil seal.

  • Why Wonepart seal there are different types of Seal application in different area?Why Wonepart seal there are different types of Seal application in different area? Leakage is one of the common failures of mechanical equipment. There are two main reasons for leakage: one is the result of mechanical processing, the surface of mechanical products must have various defects and shape and size deviations, therefore, gaps will inevitably occur at the joints of mechanical parts; the other is sealing two If there is a pressure difference on the side, the working medium will leak through the gap. Reducing or eliminating gaps is the main way to prevent leakage. The role of the seal is to seal the gap between the joint surfaces, isolate or cut off the leakage channel, increase the resistance in the leakage channel, or add a small working element in the channel, which will cause pressure on the leakage and partially offset the pressure difference that caused the leakage. Or fully balanced to prevent leakage. Sealing can be divided into two categories: static sealing between relatively static joint surfaces and dynamic sealing between relatively moving joint surfaces. Static seal usually refers to the seal between two static surfaces. There are three main categories of static sealing: gasket sealing, sealant sealing and direct contact sealing. Dynamic seal refers to the seal between relative moving parts in a machine (or equipment). 1 Packing seal Packing seals are mainly used for the dynamic sealing of the moving parts of process machines and equipment in the machinery industry, such as centrifugal pumps, compressors, vacuum pumps, mixers, reactor shaft seals and reciprocating pumps, plungers or piston rods of reciprocating compressors, And to make the seal between the valve stem of the linear and spiral motion valve and the fixed body. The basic form of stuffing box is: (1) Asbestos packing: Both temperature resistance and corrosion resistance are very good, but when used alone, the sealing effect is not good, so it is always impregnated or added with other materials. Oil-impregnated asbestos packing: There are two basic structural forms, one is twisted and the other is braided. It can be divided into round and square. (2) Teflon braided packing: The PTFE tape is braided into packing, which has excellent corrosion resistance and can be used in cryogenic media. (3) Rubber O-ring: In the low pressure state, the sealing effect is good. The use temperature is restricted, such as natural rubber can only be used at 60°C. For O ring you could find details on our web http://www.wonepart.com/product/o-ring, you could find the part that you want. (4) Plastic molding filler: Generally made into three-piece type, but also can be made into other shapes. The plastics used are mostly polytetrafluoroethylene, and nylon 66 and nylon 1010 are also used. (5) Soft packing seal Soft fillers, also known as mud-like fillers, are advanced "packings" made from a new generation of high-performance synthetic fibers with special barrier agents and lubricants. The soft packing has any size and shape, and it is easy to install. It can be injected directly through a special high-pressure gun. It does not need to be pre-cut like a traditional packing, and it can be applied to any size of the packing cavity.

  • What is UN piston seal? In fact, UN seal refers to the universal sealing technology between piston and piston rod, commonly known as UN seal or piston seal. And because the sealing material generally used is polyurethane rubber products, it is also called polyurethane seal. 1. The role of UN polyurethane seal and engineering working temperature Because the UN piston seal is made of polyurethane rubber, its polyurethane hardness is generally between 90. Polyurethane seals have the same size and cross-section, and the height of the inner and outer sealing lips are the same. Its sealing function is to prevent the intrusion of particulate dust, dirt and foreign objects. It is a universal shaft hole sealing ring series. The engineering environment temperature is between -40℃~+100℃. 2. The advantages of UN polyurethane seals and the reasons for their widespread use The advantages of the UN seal of the piston polyurethane are the remarkable extrusion impact resistance, the resistance to compression and the good wear resistance in the working state, and it is very suitable for operation under harsh engineering environmental conditions. Why are UN piston seals widely used? Because of its advantages, it can be used to prevent dust from heavy-duty German mechanical seal box industrial hydraulic seals (such as various types of hydraulic cylinders, cylinders, piston rods or piston seals), and has a good sealing effect.

  • The key part of wonepart hydraulic pump system applied in construction machines A hydraulic pump is a hydraulic component that provides pressurized liquid for hydraulic transmission, and is a kind of pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into liquid pressure energy. The figure shows the working principle of a single plunger pump. The cam is rotated by a motor. When the cam pushes the plunger upwards, the seal volume formed by the plunger and the cylinder decreases, and the oil is squeezed out of the seal volume and discharged to the place where it is needed through the one-way valve. When the cam rotates to the lower part of the curve, the spring forces the plunger down to form a certain degree of vacuum, and the oil in the oil tank enters the sealed volume under the action of atmospheric pressure. The cam causes the plunger to rise and fall continuously, the sealing volume periodically decreases and increases, and the pump continuously sucks and discharges oil.For Pumps, there are different kinds of brands, such as Kawasaki, Rexoth, Komatsu, Linde, Eaton, Parker, Kayaba, HAVE, SUER, UCHIDA,NACHI, JEIL, TEIJIN SEIKI, TOSHIBA, YUKEN, ITALY SAM, DAKIN, ITALY SAM, DENISON, OILGEAR, AND SO ON. Take Kawasaki for example,there are Model K3V112 Series, K3V140 Series, K3V180 Series, K3V280 Series, K5V140 Series, K5V160 Series, K5V200 Series and so on, if you are interested in hydraulic pump assemble or pump spare parts, pls feel free to contact our WONEPART spare parts center www.wonepart.com or email info@Wonepart.com or whatsapp:+86-15860751932, we will feel free to support you at any time.
