Advantages of Mechanical Seal

Improved Safety

Mechanical seals provide a high level of safety by preventing leaks and spills. They can handle high-pressure and high-temperature environments, ensuring that fluids are contained within the equipment. This reduces the risk of accidents, environmental damage and equipment failure.

Reduced Friction and Heat Generation

The design of mechanical seals significantly reduces frictional losses. Unlike packing glands, which rely on compression to create a seal and can generate considerable friction and heat, mechanical seals utilize a hydrodynamic or hydrostatic film between the faces. This fluid film minimizes direct contact, reducing friction and wear. Advanced designs, such as spiral groove or wavy face patterns, enhance fluid film stability, further reducing heat generation and improving seal longevity.

Increased Efficiency

Mechanical seals reduce friction and wear, which results in more efficient equipment operation. Less energy is required to overcome the resistance caused by friction, allowing equipment to operate at a higher capacity. This can result in increased productivity and lower operating costs.

Versatility

Mechanical seals can be used in a wide range of applications, from pumps and compressors to mixers and agitators. They are available in a variety of materials, sizes and designs to meet specific industry requirements. This makes them a versatile choice for many industrial applications.

Environmental Friendliness

Mechanical seals are an environmentally friendly choice, as they reduce the risk of leaks and spills that can harm the environment. They also require less maintenance, which reduces the use of resources and waste production.

Application of Mechanical Seal

Pump equipment

Mechanical seals are widely used in pump equipment and can reliably seal seawater, mud, oil, chemical media, etc. Specific applications include seawater desalination, sewage treatment, petrochemical, thermal power generation and other industries.

Compressors and fans

In gas compressors and fans, mechanical seals can seal various gas media, such as air, nitrogen, liquefied gas, etc., to ensure the normal operation of the equipment.

Mixing equipment

Suitable for mixing equipment such as mixing tanks and reactors, it can seal solids, liquids, gases and other media, and is widely used in chemical, pharmaceutical and other industries.

Oil and gas extraction

In oil extraction and natural gas collection, such as oil wells, gas wells, water pumps and other downhole equipment, mechanical seals can effectively prevent medium leakage.

Food, pharmaceuticals and medical devices

Mechanical seals are also used in agitators and pipeline seals in food processing, as well as pump equipment in medical devices.

‌Other rotating fluid machinery

Mechanical seals are also used in centrifuges, reactors and other equipment to ensure that liquid or gas does not leak through the rotating shaft‌.

Components Of Mechanical Seals

Mechanical seals consist of several key components that work together to create an effective seal. The main parts include:

Rotating Primary Face

This component is fixed to and rotates with the shaft, sealing against the stationary primary sealing element.

Stationary Primary Face

Fixed to the stationary housing of the pump or other equipment, this face seals against the rotating primary sealing element.

Mechanical Loading Devices

These components, such as springs or metal bellows, bias the primary sealing elements in contact to initiate sealing.

Secondary Seals

These static and dynamic seals, often O-rings or gaskets, seal between the mechanical seal components and the equipment shaft and housing.

Drive Mechanisms

Set screws and drive pins are examples of components used to provide rotation to the rotating primary seal face.

Installation Method Of Mechanical Seal

The installation method of mechanical seal needs to pay attention to the following key steps and precautions:

‌Preparation and inspection

Prepare the required tools and check the tools to ensure that the tools are intact and suitable for use. ‌
Clean all related parts such as seals, shafts, sealing chambers, glands, etc. to ensure that they are clean and free of impurities.

‌Lubrication and installation

To reduce friction resistance, the part where the mechanical seal is installed on the shaft can be lubricated with a thin layer of oil. However, it should be noted that if the rubber O-ring is incompatible with oil, soapy water or other suitable lubricants should be applied.
Install the static ring and the gland on the shaft together, taking care to avoid collision with the shaft. Then install the dynamic ring assembly to ensure that the positions of all parts are correct.

‌Fixation and adjustment

The set screws of the spring seat or transmission seat should be tightened evenly in several times to avoid deflection or damage to the parts.
Before fixing the gland, push the compensation ring by hand for axial compression. After loosening, the compensation ring should be able to rebound automatically without jamming. Then tighten the gland bolts evenly.

‌Trial run and inspection

After installation, conduct a trial run to check if the mechanical seal has any leakage or other abnormalities.
If any abnormality is found, the machine should be stopped immediately for inspection and adjustment to ensure that the mechanical seal works properly.

FAQ

Q: How long is your delivery time?

A: Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according to quantity.

Q: Can I get an sample to check the quality of products?

A: Yes. We can send you samples to check the quality within 3-5days.

Q: What payment terms do you accept?

A: We accept T/T, Western Union, Paypal and Escrow, L/C, etc.

Q: Can you make customized products for us?

A: Yes. Customized products are available according to your drawings or working conditions.

Q: Could you design it if I don’t have drawings or pictures for custom products?

A: Yes,we can make the best suitable design in accordance with your application and working conditions.

Q: Can you run a mechanical seal dry?

A: Generally, liquid lubricated seals should not be dry run regularly or for prolonged periods. However, some mechanical seals with a carbon face will tolerate marginal lubrication and short, intermittent periods of dry running.

Q: What are the requirements for mechanical seals?

A: These are the essential requirements: Seal faces must be flat and polished. Seal faces must be installed perpendicular to the shaft. Spring force must be sufficient to maintain contact of the faces.

Q: What is the life expectancy of a mechanical seal?

A: Properly installed and stabilized mechanical seals should get 3-5 years of useful service. If they are getting less, then they could be installed on worn equipment that needs shaft support, or flush fluid characteristics need analysis.

Q: What are the checks before installing mechanical seal?

A: While the mechanical seal is installed into pumps and other rotary devices, check and make sure the axial movement of the shaft is no more than 0.3 mm. At the stage of the shaft or shaft sleeve up to which the mechanical seal is going to be installed, must be rounded edged with 3 x 10°.

Q: Can you reuse a mechanical seal?

A: The reusability of a mechanical seal depends on several factors, including the type of seal, its condition, application requirements, and manufacturer recommendations. While it may be possible to reuse a mechanical seal in some cases, doing so comes with inherent risks that must be carefully evaluated.

Q: What is the difference between single mechanical seal and double mechanical seal?

A: Double (or dual) mechanical seals are designed to ensure maximum sealing safety. These seals virtually eliminate leakage of the fluid or gas being handled in pumps or mixers. Double seals provide a level of safety/zero emissions compliance not possible with single seals.
