SKF imported bearing sealing test is often the check of the assembly and operation reliability of the cylinder sealing part and its joint after assembly; like the sealing and connection of the cylinder port, the piston of the cylinder (between the rod cavity and the rodless cavity) , static seals and sealing conditions, etc.. Because the experimental pressure is very large; especially for the pressure test without the rod cavity; if there is no tooling to accept the pressure from the rodless cavity, the piston exerts a large pressure on the piston rod; It is definitely not acceptable to accept the connection of the mouth. Therefore, this type of pressure test is often carried out after carefully assembling the cylinder; during the commissioning of the final assembly machine.
Use the frame of the machine to which the cylinder belongs to accept a lot of pressure. If there is no problem in the assembly of the cylinder; the cylinder will be smooth in the final assembly pressure test; this eliminates the need to test the tooling after the cylinder is assembled; Corresponding working hours; and will shorten the production cycle; it is beneficial to the production, if there is a problem in the assembly of the cylinder; it will be exposed during the assembly and commissioning; it will be unloaded to disassemble and reassemble; instead, it will take time and labor to affect the progress of production; Small loss. This is often the result of the operator's inability to carefully view and carefully work.
Therefore, before installing SKF bearings, carefully check whether the scale accuracy of the relevant parts can match the drawings; the failure of the sealing parts is often promoted by the dimensional accuracy of the sealing groove or the roughness of the sealing surface does not reach the demand; secondly, the sealing parts The shape of the several should be carefully examined; especially the view of the sealing lip; the seals with irregular shapes, lack of meat, small cracks, etc. cannot be loaded into the product.
Others; the raw materials, hardness and other objectives of SKF imported bearing seals should be compared with the product certificate and the outbound order. For example, the O-ring seal has I-I-I-four pressure levels; Corresponding from low to high; especially for those who have no experience; the same standard seal; single from the surface is often difficult to distinguish. If the low pressure seal is accidentally installed in the high pressure part; also think that the assembly process There is no problem; the result is that the seal is easily broken down during the experiment or operation to form a seal failure or a significant shortened service life; its impact and loss can be imagined.
