Excellent hydraulic seal factory: Mechanical seals form a critical part of any mechanical operation involving fluid movement through rotational shafts, such as in the case of pumps. These seals ensure that the fluid does not leak out of a closed system and contaminants do not enter the system. In pumping applications, mechanical seals are placed at the point of entry or exit of a rotating shaft, preventing the pressurized fluid from escaping the pump housing and withstanding the friction generated from the shaft rotations. Read on to learn how mechanical seals work and explore some popular use cases of seals in pump applications. Discover additional details on rod seals manufacturer.
The Primary Seal – While two of the sealing points in a seal design are simple static seals, the seal between the rotating and stationary members needs a little more consideration. This primary seal is the basis of all seal design and is essential to its effectiveness. The primary seal is essentially a spring loaded vertical bearing – consisting of two extremely flat faces, one fixed, one rotating, running against each other. The seal faces are pushed together using a combination of hydraulic force from the sealed fluid and spring force from the seal design. In this way a seal is formed to prevent process leaking between the rotating (shaft) and stationary areas of the pump. The surfaces of the seal faces are super-lapped to a high degree of flatness; typically 2-3 Helium light-bands (0.00003” / 0.0008mm). If the seal faces rotated against each other without some form of lubrication they would wear and quickly fail due to face friction and heat generation. For this reason some form of lubrication is required between the rotary and stationary seal face; this is known as the fluid film.
It can maintain stable performance after prolonged exposure to various corrosive compounds. Due to its lack of polarity, low unsaturation, and high chemical stability, our gasket has high resistance to various polar chemicals such as alcohols, acids (acetic acid, hydrochloric acid, etc.), strong base (sodium hydroxide, oxidant, hydrogen peroxide), detergents, animal and vegetable oils, ketones and certain esters. It is designed to have excellent aging resistance and excellent resistance to compression set and compression stress relaxation. Therefore, our gasket has significant advantages over other conventional gaskets. Its excellent materials and manufacturing process enables it to achieve effective sealing when exposed to corrosive chemicals, friction, high temperatures or very low temperatures. At the same time, it is easy to install and has industry-leading creep resistance, which saves users a lot of time and cost and increases productivity.
DMS Seals piston seals can be used very effectively in the clearance between the two chambers of the hydraulic cylinder and cylinder. The piston seal is pushed by the pressure of the fluid. Its good working performance can improve the efficiency of the machine. Due to its excellent resistance to leakage, it helps the machine to extend the machine’s working life. Our seals provide the best tight adhesion for the sealing system with low internal leakage and frictional resistance.
Influence of flange form: Different flange forms require different gaskets. Smooth-faced flanges are generally only used for low pressure, with soft thin gaskets; under high pressure, if the strength of the flange is sufficient, smooth-faced flanges can also be used, but thick soft gaskets should be used, or inner belt reinforcement should be used. Wound gasket for ring or reinforcement ring. In this case, metal gaskets are also not suitable, because the required pressing force is too large, resulting in large deformation of the bolts, making the flange difficult to seal. If a metal gasket is to be used, the smooth surface should be reduced to reduce the contact area with the gasket. In this way, under the condition of the same bolt tension, the compressive stress of the reduced narrow smooth surface will increase.

Although construction machinery looks extremely complex, the common characteristics that can be summarized are: Usually work outdoors. The work site often changes, and some can move by themselves. The working environment is usually dusty or stained. Nowadays, construction machinery generally adopts hydraulic transmission, because hydraulic transmission has the following obvious advantages compared with mechanical transmission: The power-to-volume ratio is large and the location arrangement is easy. It can realize stepless speed change. It is easy to realize overload protection. Less shock, vibration and noise.
It can be used as a guide ring for the piston rod to support and guide the piston rod. It has excellent vibration damping performance and is simple and safe to install. It is made of metal and plastic materials. It can prevent work stagnation and violent vibration. The embossed structure facilitates the formation of lubricating micro-pits and improves lubrication. At the same time, the seal prevents the intrusion of tiny foreign objects and protects the sealing system.
