Hydraulic prop is generally composed of piston, piston rod, cylinder block three parts. Because the support work, the column bearing capacity is large, and the drop column force is small, so the piston rod diameter is larger, often use hollow structure, in order to ensure sufficient stiffness of the piston is generally y sealing ring, copper ring guide, cylinder bottom welding. The cylinder block and the cylinder head are connected by steel wire, thread or clasp. In order to prevent the external coal seam and other stolen goods into the cylinder block, the guide sleeve should be equipped with a dustproof ring. For the single telescopic column, in order to expand the support height of the hydraulic support, can use mechanical extension rod, the head structure of the column is spherical, and the connection between the top beam or the base with pin shaft or block fixed, in order to make the column in the work by a certain adaptability.
The liquid supply method of hydraulic prop consists of two ways: internal liquid supply and external liquid supply. In addition to the double telescopic column with internal liquid supply mode, the single telescopic prop is mostly external liquid supply mode, which is simple in structure, convenient in processing and maintenance.

The hydraulic prop is the main component to support and carry the hydraulic support, it directly affects the performance of the hydraulic support. Therefore, in addition to reasonable working resistance and reliable working characteristics, hydraulic prop must also have enough compressive and bending strength, good sealing performance, simple structure and suitable for the work of hydraulic support needs.

Fixed protection, such as wooden brackets, shall be applied in the delivery and transportation of y303-30 hydraulic support columns. In case of large quantities, such as hydraulic jacks, which are delivered in batches, shall be bundled firmly to avoid falling off, extrusion, rolling collision and other damages. If it is in winter, the product should be injected with antifreeze according to the low temperature of the applicable area and the transportation distance. In other seasons, the emulsion in the column of Y303-30 hydraulic support should be emptied. However, the transportation and storage process of the column after the drainage should be guaranteed, and no corrosion phenomenon should occur inside. If the hydraulic support column of Y303-30 has been stored for more than three months, the emulsion in the hydraulic support column should be checked for deterioration. If so, the emulsion should be replaced. When the drainage method is adopted, the rust should be checked. The hydraulic support column of Y303-30 should be paid attention to and ensure that the joint seat is not damaged during the use, and the transportation package should be strong and reliable. The column should be loaded and unloaded lightly in the process of transportation. Special attention should be paid to the joint seat so as not to damage the interface and affect the connection use of the hydraulic support column. In fact, the above methods are not only for y303-30 hydraulic support column, but also for all kinds of hydraulic support jack cylinders. In transportation, storage and use, some problems can be avoided for the hydraulic support column or hydraulic support jack. Henan Shuangzhi Machinery as hydraulic support accessories manufacturers, can produce and process hydraulic support column, hydraulic support jack, bed beam, bed, bottom adjustment beam and other accessories, welcome new and old customers to consult understanding, looking forward to working with you!
