The skeleton oil seal specifications are complete, and samples are welcome to customize. The threaded oil seal is a small part that isolates the parts that need to be lubricated in the transmission parts from the output parts, so as to prevent the leakage of lubricating oil. According to the new market quotation of threaded oil seals, the price of threaded oil seals is not high, so they are widely used. The proper purchase of threaded oil seals is very necessary. The quality of performance and quality directly affects whether agricultural machinery and various mechanical equipment will leak oil. The following sections describe the two aspects that need to be based on the purchase of thread oil seals.
1. Purchase according to appearance
When purchasing a threaded oil seal, you should pay attention to its appearance. The surface of the threaded oil seal must be smooth and free of defects such as burrs, cracks, air bubbles, missing corners and impurities embedded. The bonding between the rubber and the reinforcing ring should be tight and not loose, and the inner and outer surfaces should not expose iron. At the same time, the surface of qualified threaded oil seal parts has both a certain precision and a bright finish. The more important the parts, the higher the precision, and the stricter the packaging and anti-corrosion. When purchasing, you should pay attention to inspection. If it is found that the threaded oil seal parts have rust spots, mildew spots, or rubber parts are cracked, lose elasticity, or the surface of the threaded oil seal has obvious turning tool lines, it should be replaced.
2. Purchase according to working conditions
First, it can be selected according to the working medium. The threaded oil seal is eroded by oil during long-term work. In order to prevent the rubber from softening, hardening or cracking prematurely, the oil seal material should be required to have good compatibility with the sealed medium. To ensure that the size of the oil seal changes less during operation. At the same time, it can be selected according to the working pressure. Under the condition of high working pressure, the pressure-resistant threaded oil seal with a short waist and a strengthened metal skeleton and a high-temperature-resistant rubber threaded oil seal should be used.
From the above description, when purchasing threaded oil seals, it is necessary to choose according to the appearance and the working conditions. At the same time, when people decide which product is the best screw oil seal, they also need to refer to factors such as the popularity of the manufacturer, industry experience, production scale, user feedback and evaluation, and cost-effectiveness. At the same time, it is also very necessary for the thread oil seal to be guaranteed after sales, which can solve the worries of users.
