Nitrile-butadiene rubber: Nitrile-butadiene rubber is a general-purpose sealing material, which is synthesized from acrylonitrile and butadiene, and has good resistance to the following media.

O-ring selection skills and failure analysis

2022-10-21

O-rings are usually selected as large-section O-rings as much as possible. Under the same gap, the volume of the O-rings squeezed into the gap should be smaller than the maximum allowable value.

Causes of damage to O-rings

2022-09-28

The friction of the seal sliding against the metal surface causes the seal to wear. Oil contaminants (especially metallic particles). Excessive roughness of the metal surface, too tight installation and other factors accelerate this wear.

Precautions for the installation of automobile thread oil seal

2022-09-23

There are many threaded oil seals in automobiles. Although the price of threaded oil seals is not high according to the new market quotations of threaded oil seals, if the correct selection and installation of oil seals are ignored, oil leakage or liquid leakage failure will occur in the automobile, resulting in Problems such as pulling the cylinder, holding the shaft, and burning the gear. Therefore, every car maintenance personnel should pay attention to the selection and installation of threaded oil seals. Next, the editor will elaborate on the precautions for the installation of automotive thread oil seals?

What aspects need to be based on the purchase of threaded oil seals?

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.

How to improve the assembly quality of threaded oil seals

2022-09-19

At present, with the development of the automobile industry and the electronic communication industry, the threaded oil seal has an irreplaceable practical significance in the oil seal industry, and the after-sales service of the threaded oil seal is guaranteed. The threaded oil seal is used to seal the mechanical components of grease, and it isolates the parts that need to be lubricated in the transmission parts from the output parts, so as not to allow the leakage of lubricating oil. The assembly of the threaded oil seal is very important. The following small series will explain how to improve the assembly quality of the threaded oil seal?

What are the functions of the external thread oil seal

2022-09-16

The basic parts industry plays a supporting role in the operation of other industries, and the oil seal is a more important part in the automobile maintenance industry. In order to prevent the various mechanical structures of the automobile from experiencing a large degree of wear and difficulty in operation after a long period of operation, external thread oil seals are required to seal the lubricating fluid in the corresponding worn places.

Precautions for skeleton oil seal

2022-06-01

Skeleton oil seals are widely used in aviation, automobiles, motorcycles, railways, vehicles, ships, home appliances, construction machinery and other industries. Suitable for rotary motion and reciprocating motion seals. Installed in various heavy-type engines, gearboxes, axles, ships, cylinders and other parts. Mainly prevent the penetration of the sealed medium (gas. liquid.) and the entry of external foreign bodies into the body.

Application principle of O-ring

2022-09-06

The O-ring is a two-way sealing element. During installation, the initial compression of the O-ring in the radial or axial direction determines the initial sealing ability of the O-ring. The force generated by the system pressure acting on the O-ring is its total sealing force; the seal increases as the system pressure increases.

O-ring application introduction

2022-06-01

O-ring O-ring (O-rings) is a kind of rubber sealing ring with a circular cross-section. Because its cross-section is O-shaped, it is called an O-ring rubber sealing ring, also called an O-ring. It began to appear in the mid-19th century, when it was used as a sealing element for steam engine cylinders. O-rings are the most common mechanical design for seals because of their low cost, simplicity of manufacture, reliable function, and simple installation requirements. O-rings are subjected to pressures of tens of megapascals (kilo pounds). O-rings can be used in static applications as well as in dynamic applications where there is relative movement between components, such as shafts of rotary pumps and pistons of hydraulic cylinders.
