Jinyuan is committed to becoming the world's leading custom air compressor manufacturer
dry screw vacuum pump comes from Guangdong Jinyuan Equipment Technology Co., Ltd, a sought-after company gaining a large volume of customers' trust with the superior product performance. The production technique implemented is advanced and safely guaranteed. The design style of these products is generously bold and novel, attracting eyes. Strict QC procedure including process control, random inspection and routine inspection ensures excellent product quality.
As a well-known brand in the China market, Jinyuan Air Compressor has gradually tapped into the international market. We feel grateful to our customers for their high evaluation of our products, which helps bring more new customers. Our products passed many certification and we would like to let customers know that these honors are worth through providing excellent products and services.
At Jinyuan, our commitment to quality and services shapes everything we do. Partnering with our customers, we seriously design, manufacture, package and ship. We endeavor to put the standardized services to the best. dry screw vacuum pump is the showcase for the standardized services.
The screw compression host of Jinyuan uses high efficiency shaft seal structure, compared with the existing technology, static ring made of phosphorus bronze material, phosphorus bronze has higher corrosion resistance, wear resistance, impact does not spark, has automatic centering, can be radial load at the same time, the lubrication without maintenance characteristics, reduce the axial stress of the shaft. The rolling rod is a shape structure, and the outer surface of the rolling rod is set with threads. Compared with the plane fitting method, it can compensate the axial movement of the shaft, reduce the requirements of shaft seal assembly, and strengthen the sealing performance, which can change the sliding friction to rolling friction, and reduce the friction performance.
The moving ring 5 and the static ring 6 are installed between the shaft 2 and the shaft seal cover 3, Moving ring 5 is made of a titanium alloy material, Titanium alloy has a high strength of hardness and wear resistance, And has a good corrosion resistance performance, Easy for long-term use, The static ring 6 is made of a phosphobronze material, Phosphorus bronze has a higher corrosion resistance, stand wear and tear, No sparks will occur during the impact, With the automatic centering, Sensitivity to skelection, High uniform shaft bearing capacity, Can be subjected to radial load, Self-lubrication characteristics without maintenance, Reduced the axial stress of the shaft 2, Where the static ring 6 is located between the moving ring 5 and the shaft sealing end cover 3, The positioning ring 7 is installed at one end of the moving ring 5 away from the static ring 6, The first insertion lever 8 is installed at one end of the positioning ring 7, The positioning ring 7 is connected with the fixed ring 9 through the first lever 8, The end of the fixing ring 9 is provided with a second insertion lever 10, The fixing ring 9 is fitted with a shock spring 11, Rolling rod 12 is a shape structure, And the outer surface of the rolling rod 12 is provided with a thread, Compared to the plane-fitting method, Can compensate for the axial movement of the shaft 2, Reduces the requirements for shaft seal assembly, At the same time it strengthens the sealing performance.
