What is a mechanical seal:
Mechanical seal is a rotary mechanical seal device. Such as pumps, centrifuges, reactors and compressors and other equipment. As the shaft through the inside and outside the device, so that the shaft and a circular gap between equipment, equipment in the medium through which gap leak out, if the equipment inside the pressure less than atmospheric pressure, the air leak within the device, so there must be a device to prevent leakage of the seal. Many different types of seals, mechanical seals have leakage due less to drink and long lifetime, so when this world is in such equipment mechanical seals shaft sealing the main. Also known as seal mechanical seal.

Mechanical seals developed rapidly in recent years, according to different working conditions de there a variety of structure, but no matter what kind of structure by the following four components:
The first part is a ring composed of Ha Tinh ring sealing face, sometimes called Friction.

The second part is composed of elastic element as the main components of the buffer compensation agency, whose role is to tightly seal faces.

The third part is a supporting ring, which ring and static ring seals. The fourth part is to ring with the axis of the transmission mechanism.

Built-in and seal any exterior differences:
Installation position by static ring can be divided into interior and exterior-type mechanical seals. Static sealing gland ring installed in (or the equivalent of sealing gland parts) inside (that is, the working chamber for the host side) of the mechanical seal mechanical seal known as the interior. On the contrary, in a sealed gland's outer ring called the installation of static externally mounted machine mechanical seals. Built-in mechanical seal for high temperature and pressure, and the medium on the ring and elastic components of the corrosion conditions are not high. Externally mounted mechanical seals for low (or negative pressure) and medium corrosive conditions.

What is within the flow and the outflow mechanical seal:
Sealing fluid leaks in the seal faces and the area between the centrifugal force in the opposite direction and the mechanical seal mechanical seal is called flow; seal fluid leakage between the seal faces with the centrifugal force in the same direction as the outflow mechanical seals. In general, multi-flow-type mechanical seal in contents in more than suits the mechanical seal is the outflow. As the outflow direction and the centrifugal force in the same direction leak, so the outflow of a large amount of mechanical seals leakage. Therefore, oil-based most industrial processes use the pump mechanical seals within the flow, pressure and temperature not only in the corrosive medium high until the outflow of mechanical seals used.

Many springs and single-spring mechanical seal by what difference:
According to the number of spring compensation mechanism can be divided into multiple springs and single-spring mechanical seals. Multiple spring compensation mechanism is called multi-spring mechanical seal; compensation agencies, only a spring known as the single spring mechanical seals. Multi-spring machine mechanical seal, also known as a small spring, small axial size of this structure, the method can be used to change the spring to change the number of elastic force, axial force is uniform, for high-speed mechanical seal, should not be used in corrosive media. Single spring mechanical seal it said the big spring mechanical seals, sealing structure is relatively simple. Some also use the spring type seal transfer torque. Big spring seal application made more, but not for high-speed.
