Company brief:

Guangzhou Suncar Construction Machinery Co., LTD., founded in 2014, is a foreign trade company specializing in the wholesale and retail of construction machinery seals. Its current business covers many regions at home and abroad.Over the years, we have focused on the innovation and development of manufacturing technology, and have a highly automated production and processing base, providing excavators, bulldozers and other equipment with high-quality sealing parts and accessories, one-stop solution to the maintenance problems of construction machinery.

Loose card always adhere to the "quality to build the core competitiveness, innovation to change the world" business philosophy, vigorously explore overseas markets, develop the science and solid brand strategy planning, on the basis of quality, each type of product made the instruction manual production technology, from raw material selection to each link of manufacturing and processing have strict standards, multilayer testing verifiC.A.Tion, to ensure product quality and performance in accordance with using the standard, size, model can accurately fit the corresponding mechanical equipment, machinery spare parts "made in China" quality feeling and the internationalization of the brand image.

Influencing factors of seals:

Hydraulic seals play a vital role in the integration of hydraulics and pneumatics. If the seals of a hydraulic and pneumatic component product are not good enough, then this hydraulic and pneumatic component product is not a good product. There are many factors that affect seals.

(1) First of all, pressure is an important factor affecting the quality of the seal. The level of pressure and the length of the pressure cycle change have a great impact on the damage of the seal (such as extrusion). The higher the pressure, the greater the impact of other factors on the performance of the seal, such as temperature, speed, seal material, clearance between the piston and cylinder, and clearance between the piston and cylinder head.

(2) Another one is temperature and friction. It is difficult to describe the maximum use temperature and minimum use temperature of a seal material, because it is the result of the combined influence of a series of factors. For the different working temperatures of the piston and the piston rod, they should be selected differently. Another is the surface roughness of the seal product, the characteristics of the surface, the pressure, the medium, the temperature, the material of the seal, the type of the seal and the speed of movement, which are all factors that affect the seal.

(3)The last one is surface treatment. Experience has shown that the characteristics of the surface of the cylinder piston and piston rod have a great influence on the life of the seal. Surface properties are often defined by the value of surface roughness RA, which is the arithmetic mean of the absolute value of the deviation of the surface shape from the centerline. However, these values ​​do not fully represent the effect of the surface condition on the seal, because even with the same roughness, different surface shape features can cause different degrees of seal wear to the seal.
