Precautions for oil seal

1. Preparations and precautions before startupa. Comprehensively check whether the mechanical seal, accessory device and pipeline installation are complete and meet the technical requirements.b. Static pressure test shall be carried out before the start of mechanical seal to check whether there i...
General representation of O-ring

General representation of O-ring

It is mainly divided into two forms, one is the inner diameter * wire diameter, the other is the outer diameter * wire diameter. At present, it is widely used abroad and at home to express inner diameter * linear diameter. For example, American Standard as568 and Japanese standard g / P are all r...
O-ring Introduction

O-ring Introduction

O-rings is a kind of rubber seal ring with circular cross section. Because of its o-section, it is called O-ring or O-ring. It began to appear in the middle of the 19th century, when it was used as a sealing element of steam engine cylinder.Because of its low price, simple manufacture, reliable f...
Selection principle of O-ring inner diameter

Selection principle of O-ring inner diameter

When selecting O-ring, first of all, try to select the new national standard. Bai with wire diameter of 2.65 and 3.55 is the most common. When the outer diameter is more than 30 and the structure size allows, try to select 0-ring with wire diameter of 3.55 to achieve greater compression and ...

O-ring Knowledge

The O-ring is composed of a low friction filled polytetrafluoroethylene (PTFE) ring and an O-ring. The O-ring provides sufficient sealing preload and compensates for the wear of the PTFE ring. The friction coefficient of PTFE is small and the dynamic and static friction coefficients are similar. ...

Oil Seal Introduction

Oil Seal Introduction

Oil seal is a sealing element used to seal the rotating shaft in mechanical equipment, and the cavity is basically a static metal framework, just like the steel bar in the concrete component, which plays a reinforcing role, and enables the oil seal to maintain the shape and tension, and at the sa...
Chassis and Hydraulic Oil Seal

Chassis and Hydraulic Oil Seal

First of all, there will be oil in the friction part of the machine during the operation. In order to prevent the oil from being scratched away from the mechanical space, the chassis and hydraulic oil seal are used. Besides the oil, it is also necessary to prevent the leakage of a pile of liquid ...
Oil Seal Working Knowledge

Oil Seal Working Knowledge

In addition to the pump capacity of the oil pump, factors such as the oil passage area and the viscosity of the oil will affect the engine oil seal.When the engine is working, the normal oil pressure must be maintained. If the oil pressure is too low, the friction surfaces will wear faster due to...
