Function, sealing, principle of use.
The main function of the carbon ring seal is for small power units. The sealing performance is relatively poor, and the function of the water ring steam seal is relatively good. It is mainly widely and commonly used in high-power turbogenerators.
For these two choices, you must judge according to the real situation. Generally speaking, the emphasis is on waterproofing.
What is the difference between lotus and lotus?
It may be normal that the shaft seal of the water ring vacuum pump does not drip. If the pump uses a mechanical seal, it will not leak.
There are two main forms of shaft seals: one is a traditional and common seal; the other is a mechanical seal.
The gasket is also called a gasketompression, commonly called gasket. The gasket is the oldest sealing structure. In ancient Chinese water-lifting machines, cotton thread was used to block leaks. The world's first steam engines also used this form of sealing. The production and development of oil and natural gas extraction technology in the 19th century led to new developments in gasket materials. In the 20th century, gaskets were favored by many industrial sectors due to their relatively simple structure, low price, and wide availability. The package sealing requirement is to drip water, approximately 6-8 drops per minute. Compaction juices serve two purposes: cooling and lubrication. When the unit is running, adjusting the gland can adjust the seal leakage.
Mechanical joint: means a joint consisting of at least one pair of end faces perpendicular to the axis of rotation which maintains fit and slides relative to each other under the action of the fluid pressure and a compensating elastic force (or magnetic force) and the cooperation of the auxiliary seals of the fluid leak device. Elastic loading and auxiliary seal are mechanical seals of metal corrugated pipes, which we call metal bellows seals. Mechanical seals have the advantages of low leakage (basically no water drops) and long service life, so mechanical seals are the most important shaft sealing method in this equipment in the world. Mechanical seals are also called end seals. They are defined in the relevant national standards as follows: “A mechanical seal consists of at least one pair ofe end faces perpendicular to the axis of rotation which maintains fit and relative alignment under the action of fluid pressure. and compensation of the elastic force (or magnetic force) and the cooperation of auxiliary joints. A device formed by sliding to prevent leakage of liquid »
The differences between the lotus and the lotus are as follows: 1. Different forms of reproduction. Lotus stamens are male and female and are primarily self-pollinated. Lotus stamens are dioecious and pollen is spread mainly by wind and insects. Therefore, lotus spreads mainly through rhizomes and divisions. 2. The types of flowers are different. The bracts of lotus flowers are relatively rounded, while the bracts of lotus flowers are relatively thin. In this regard, lotus flowers and lotus flowers are particularly easy to distinguer. 3. The leaves have different growth habits. The lotus leaves are relatively tall, and some can even protrude more than a meter above the water. Most of the leaves of the lotus float on the water, and the upper ones are close to the water at the same time. , there are obvious V-shaped gaps on the leaves.
