Mechanical Seals Buying Guide
A mechanical seal is used in the construction of machines to prevent the leakage of liquids or gases. It is a crucial component, especially in production machinery and in ensuring that the entire system operates efficiently. The seal acts as a barrier between the rotating or moving components of the machine and its stationary housing parts, thereby preventing any leakage of fluids or gases. In this buying guide, we shall explore the features of mechanical seals and what you need to consider when looking to purchase one.
Mechanical Seals Types
There are different types of mechanical seals available in the market, each with unique features and applications. Some of the common types of mechanical seals include:
1. Cartridge Seals
Cartridge seals are pre-assembled, enclosed units that are installed into the stuffing box of a pump. They have a self-aligning face and do not require any adjustments. Cartridge seals have been designed to save installation time and offer better results since they can be replaced without disassembling the equipment. These types of seals are ideal for use in applications such as chemical processing and pulp and paper production.
2. Pusher Seals
Pusher seals are commonly used in applications where high pressure, high speed, or high temperature are prevalent. These seals have an elastomer secondary seal that lubricates and cools the primary seal faces, thereby reducing heat and friction. They are designed for simple installation, and adjustments can be made at the end of the actuator.
3. Elastomeric Bellows Seals
Elastomeric bellows seals use a flexible polymer as the secondary seal that promotes easy installation and minimizes vibration. They are highly reliable in applications that require high chemical resistance and are commonly used in the chemical industry, pharmaceuticals, and water treatment plants.
4. Metal Bellows Seals
Metal bellows seals feature a balanced design that reduces the amount of axial stress placed on the seal faces. They are highly reliable and can handle high pressure, high temperature, and aggressive chemical applications. Metal bellows seals are ideal for use in applications such as refineries, power plants, and pipelines.
Criteria for Selecting a Mechanical Seal
When selecting a mechanical seal, there are several factors that you need to consider to ensure that you get the right product for your application. Here are some key criteria that will assist you in selecting the appropriate mechanical seal:
1. Fluid Type
When selecting a mechanical seal, you need to know the type of fluid that will go through the machine. The choice of seal material will depend on the fluid properties such as acidity, alkalinity, temperature, pressure, and viscosity. Ensure that the seal is compatible with the fluid type, and it will not corrode, de-laminate or leak after several operations.
2. Operating Environment
The operating conditions play a significant role in selecting the right mechanical seal. Factors such as temperature, pressure, speed, and the presence of abrasive materials will determine the correct selection of seal materials, face combinations, and installation methods.
3. Seal Configuration
The seal configuration will determine the ease of installation, performance, and cost. Single seals are commonly used in low-pressure applications and where a small amount of leakage is acceptable. Dual seals are ideal for use in high-pressure applications, where leakage is unacceptable, and emission control is a primary concern. Tandem seals are suitable for high-speed applications, and horizontal tandem seals are ideal for processing high viscosity and fibrous fluids.
4. Shaft Size
Mechanical seals come in a variety of sizes to accommodate different shaft diameters. Ensure that you choose a seal with the right size that will fit the shaft accurately. Accuracy in size, coupled with the right installation technique, will guarantee a consistent and efficient operation.
5. Seal Materials
The choice of seal material will be influenced by the type of fluid, operating environment, and seal configuration. The most common materials used for mechanical seals include carbon, ceramic, tungsten carbide, stainless steel, and hastelloy. The seal face combinations will also influence the seal materials, and it is recommended that you consult with the manufacturer for the best combinations.
6. Seal Durability
The durability of the mechanical seal is determined by the choice of seals used in the assembly. Ensure that you choose a seal with a longer lifespan that will guarantee the efficiency of the operation.
Mechanical Seal Installation
Proper installation of mechanical seals is critical in ensuring efficient operations and preventing premature seal failures. Here are some critical installation steps that you need to follow:
1. Clean the Shaft and Housing
Firstly, clean the shaft and housing with a cloth to remove any dirt, debris, or residues that may interfere with the mechanical seal installation process. Surface irregularities or corrosion can lead to seal failure and cause damage to the equipment.
2. Apply the Lubricant
Secondly, apply seal oil or lubricant to the seal and shaft surface to reduce friction and increase sealing efficiency. The lubricant should not contain any corrosive or harmful chemicals that may cause damage to the equipment.
3. Place the Seal
Position the seal onto the shaft or housing, depending on the installation method. Ensure that the seal is placed correctly and that it fits snugly onto the housing.
4. Tighten the Seal
The final step is to tighten the seal onto the housing or shaft. Tighten the seal until it is flush with the housing or shaft flange, depending on the installation technique.
Conclusion
Mechanical seals are critical components in machinery that require seals to prevent leakage and enhance efficiency. By understanding the application and choosing the right mechanical seal, you can ensure longer machine life and increased productivity. Consult with a qualified mechanical seal distributor or manufacturer to get the best product for your application. Remember to follow the installation guidelines to ensure that you get the best results.
