Special O - rings for Homogenizer Plungers
During the operation of the homogenizer, the reliability of the plunger dynamic seal plays a crucial role in the stable operation and production efficiency of the equipment. Our rubber O - ring with a Shore hardness of 90 is specially designed for the dynamic seal of the homogenizer plunger. Its various performances have been strictly tested and optimized to meet the requirements of complex working conditions.
I. Product Performance
Excellent Sealing Performance: Adopting a unique rubber formula and combined with the characteristics of 90 Shore hardness, it can still closely fit the plunger and the plunger chamber wall under the high - speed reciprocating motion of the plunger. It can effectively resist a high pressure of up to 100MPa, prevent material leakage, ensure the stable internal pressure of the equipment, and maintain the high - efficiency operation of the homogenizer. At the same time, it has good sealing adaptability to different media such as oils and aqueous materials.
High Wear - Resistance: Through special process treatment and the addition of wear - resistant additives, it has excellent wear - resistance. It can withstand long - term and high - frequency friction, effectively extend the service life of the O - ring, reduce the maintenance frequency of the equipment due to the wear of the sealing parts, and reduce downtime and maintenance costs.
Broad Temperature Resistance: It can maintain stable physical properties in the temperature range from - 20°C to 150°C. Whether in a cold production environment or a high - temperature processing process, it can normally play its sealing role and avoid the influence of temperature changes on the sealing effect due to the hardening or softening of the rubber.
Good Elasticity and Flexibility: While ensuring high hardness, it maintains good elasticity and flexibility. The tensile strength reaches 18MPa, and the elongation at break is 350%. It can closely fit during the movement of the plunger, effectively compensate for the gaps caused by processing accuracy and assembly errors. And after continuous deformation during frequent reciprocating movements, it can still quickly return to its original shape without cracks or fractures.
II. Product Parameters
Dimension Parameters
Inner Diameter: Multiple specifications from 10mm to 50mm are available, and the tolerance is precisely controlled within ±0.1mm to ensure a perfect fit with plungers of different diameters.
Outer Diameter: Designed according to the inner diameter of the plunger chamber, it can form an appropriate interference fit after installation, generally 0.5mm to 1.5mm smaller than the inner diameter of the plunger chamber.
Cross - Section Diameter: Standard sizes include 2mm, 3mm, 5mm, etc., and the tolerance is controlled within ±0.05mm to ±0.1mm to meet the sealing requirements under different working conditions.
Material Parameters
Hardness: Shore hardness 90A, which ensures pressure resistance while taking into account a certain degree of flexibility.
Tensile Strength: 18MPa, ensuring that it will not easily break when subjected to tensile force.
Elongation at Break: 350%, ensuring that the O - ring can return to its original shape after deformation.
Working Parameters
Working Pressure: Suitable for a maximum working pressure of 100MPa, which can meet the working conditions of most high - pressure homogenizers.
Working Temperature: A wide working temperature range from - 20°C to 150°C, adapting to various complex production environments.
Reciprocating Speed: It can adapt to a reciprocating speed of 0.5m/s to 2m/s, meeting the needs of homogenizers with different working frequencies.
III. Application Advantages
Easy Installation: It can be installed without complex tools and professional skills, saving installation time and labor costs.
Wide Industry Applicability: It is suitable for homogenizers in various industries such as food, pharmaceutical, and chemical industries. It can ensure the purity and safety of materials during the processing process and is an ideal choice to improve the working efficiency and stability of homogenizers.
IV. Professional FAQs
Q: How to determine whether the O - ring has reached the end of its service life and needs to be replaced?
A: When obvious wear, deformation, cracks, or a decline in sealing performance leading to material leakage occurs, the O - ring needs to be replaced in a timely manner. At the same time, a regular replacement plan can be formulated based on the operating hours and working frequency of the equipment, combined with past usage experience.
Q: What should be noted when using this O - ring in different media?
A: Although it has good adaptability to a variety of media, it is recommended to conduct compatibility tests before contacting special chemical media. For example, some highly corrosive media may affect the performance of the rubber material. Appropriate protective measures should be selected or more chemical - resistant materials should be replaced according to the actual situation.
Q: How to ensure the correct installation position and pre - compression amount of the O - ring during installation?
A: Before installation, carefully clean the surface of the installation groove and related components to avoid impurities. During installation, ensure that the O - ring is evenly embedded in the groove without distortion or skew. The pre - compression amount can refer to the product installation manual. By accurately measuring the dimensions of the groove and the O - ring, an appropriate pre - compression amount can be ensured. Generally, the pre - compression rate is between 15% - 30%.
Q: If the working pressure exceeds 100MPa instantaneously, will this O - ring fail immediately?
A: This O - ring is designed to withstand a pressure of 100MPa. If the pressure exceeds this value instantaneously for a short time, it may not necessarily fail immediately, but it may have a certain impact on its service life and sealing performance. If over - pressure situations often occur, it is recommended to check the equipment working conditions in a timely manner and consider selecting a sealing product with a higher pressure - resistance level.
