The difference between mechanical equipment seals and hydraulic press seals

The difference between mechanical equipment seals and hydraulic machine seals Mechanical equipment seals are one of the basic mechanical components with high precision and complex structure. core components. Its sealing characteristics and service life depend on many factors, such as model selection, precision of equipment, proper installation and application, etc. Generally, it is difficult for everyone to distinguish between mechanical equipment seals and hydraulic press seals, and usually think that they are the same item. 1. Definition of mechanical equipment seals and hydraulic press seals: Mechanical equipment seals are one of the basic components of mechanical equipment with high precision and complex structure. The core components of refrigeration compressors, submersible motors and other facilities. And sealing characteristics and service life depend on many factors, such as model selection, precision of equipment, proper installation and application, etc. The sealing performance of the hydraulic press is stipulated by pressure, and the fusion surface is required to have a certain degree of smoothness. The sealing components are mostly made of plastic, and the actual effect of the closed type can be achieved according to the partial deformation of the seal. 2. Mechanical equipment seals and hydraulic machine seals are classified into mechanical equipment seals Model specifications: container type sealing products, light mechanical seal products, heavy machinery sealing products, etc. Hydraulic machine seals: lip seals, The common components of V-shaped seal ring, U-shaped seal ring, Y-shaped seal ring, YX-shaped seal ring and hydraulic cylinder are mainly bud ring, Glyn ring and step seal. 3. Selection of seals When purchasing seals for maintenance, most customers choose to buy according to the specifications and colors of the test products, which can only increase the difficulty of purchasing, and the target may not be able to choose a suitable product. It is recommended to use the following procedures to improve the accuracy of the purchase of seals: 1. Fitness movement position - first determine the operational position of the geographical position of the seal, such as reciprocating, rotating, screwing or stationary. 2. The key to tightness - for example, the main action point of the decision is the support rod seal of the nominal diameter or the main action point is the piston rod seal of the diameter, etc. 3. Temperature level - check the operating temperature from the original mechanical equipment instruction manual or evaluate the working temperature according to the real working environment, and decide on the application of raw materials. For the indication of relevant temperature levels, please refer to the following FAQs for production and processing users. 4. Specifications and dimensions - most customers buy according to the old samples that have been used, but the seals will be greatly affected by temperature, pressure and damage after a period of use. As a reference, a stronger method is to measure the metal material groove specification of the geographical location of the seal, and the accuracy will be higher. 5. Pressure level - Check the relevant data information from the original mechanical equipment instruction manual, or carefully observe the hardness and structure of the original seal and deduce the pressure level in the work. For the indication of the relevant pressure level, please refer to the following FAQs for manufacturing customers.
