The soil solution sampler is a professional instrument for extracting soil solution and is widely used in soil solution sampling. The successful application of this instrument has provided an important means for many research areas in the laboratory and various field tests in situ to repeatedly extract soil solution samples and monitor the composition of soil solution. In the agricultural field, the soil solution sampler has become an important tool for the study of crop nutrients and absorption, groundwater pollution investigation and control. In the process of use, what are the installation methods for the soil solution sampler? In general, according to the different sampling occasions, the soil solution sampler can use different installation methods, which can be mainly divided into in-line, oblique insertion and buried buried oblique insertion-in-line insertion. Among them, the in-line type can be divided into the ground inline type and the buried type inline type. The ground-on-line type refers to the vertical installation of the soil solution sampler. The center of the clay head is located at the designed sampling depth and the rear end of the sampler cavity is exposed above the ground. The burial type is to still install the soil solution sampler in the vertical direction. The center of the clay head is located at the designed sample depth, but the sampler is buried in the soil. Only the sampler's water intake and the exhaust pipe lead to the ground. . Both methods are suitable for field or other experimental field applications. In addition, in some occasions, the use of the in-line installation of the soil solution sampler has a great influence on the ground conditions, so it is necessary to use a diagonal insertion type installation. In field trials or other field tests, the soil solution sampler can also be installed in a burr-inclined plug-in installation, that is, no burr-inclined plug-in installation on the soil profile, used in the lower part of the soil profile. Bury-in-place installation, while the sampling and extraction tubes of the sampler can be concentrated in a fixed position for easy sampling operation. From this it can be seen that the installation method of the soil solution sampler is very flexible and varied. In the actual use process, we should select the appropriate installation method according to the site conditions and the actual sampling requirements. Improve the sampling effect of the soil solution sampler to ensure the accuracy and validity of the measurement results.
Conveyor Idler seals are used to keep substances such as grease and lubricant in, while keeping dirt, fluids, and other contaminants out. One advantage to this type of seal is that when small amounts of leakage occur across the seal, as is inevitable, contaminants from the outside still can't get all the way inside, and the materials being sealed may not make their way all the way to the other end. This minimizes fouling caused by mixing of contaminants and sealed fluids.
The Labyrinth Seal has a number of grooves which interlock with other grooves or teeth. This differs from most traditional seals, which use a single lip in an attempt to seal an opening. With the labyrinth seal, each groove acts as its own lip, distributing pressure across the seal rather than concentrating it in one area. While a labyrinth seal cannot deal with high pressure differentials, it can be used in many other types of environments.
Two of the most important things that must be accomplished in order to extend bearing life is to keep lubrication in, and contamination out. That`s the important function of a seal. There are many types of seals that can serve various functions.
