Preparation of special construction and agricultural machinery for the spring-summer season, when it is especially actively used for its intended purpose, includes a mandatory check of hydraulic equipment. As a rule, during the so-called “winter downtime”:
- Connecting elements for hydraulic pumps and amplifiers.
- High-pressure hoses that transmit the force from the pump to the working elements.
They lose their elasticity, which leads to a breach of tightness with all the ensuing consequences - simple equipment, complex expensive repairs in the field.
And if there are no problems with replacing gaskets in most workshops, then the acquisition of new hoses, especially for imported equipment, requires knowledge about their classification, which is carried out according to international standards and looks like this:
- 1ST - a product made of rubberized fabric, additionally contains one layer of brass-plated wire braid.
- 2ST - Includes two layers of brass plated wire.
- 1SN - in addition to the wire braid, they have a thin inner layer of oil-resistant rubber.
- 2SN - respectively two layers of braid and a thin inner layer of rubber.
Having decided on the standard of the desired high-pressure hoses , it is necessary to clarify the size of the threaded connecting elements (nuts from 17 to 41 mm), with with the help of which it is installed in a closed hydraulic system, as well as to determine the length (from 0.2 to 3 m). If there is no technical description for the equipment containing this dimensional information, the measurement can be carried out independently, using the available RVD as a sample.
How to get the right pressure hose
You can save yourself from the tedious search for the necessary hoses using the website of a company that supplies almost all types of oil-resistant hoses, including the most popular models of the 2SN class, equipped with 24 or 32 mm nuts, directly from manufacturers. The products presented in the online catalog correspond to the declared parameters and have a quality guarantee.
