Performance Introduction of Combined Packer

Combination seal is one of the most important downhole tools in petroleum engineering, which is widely used in various production links of oil and gas exploration and development. It is located between the tubing and the hose or between the hose and the borehole wall, and is used to seal off the annular space between the tubing and the hose or between the hose and the borehole wall. Among them, the sealing element (rubber sleeve) made of non-metallic materials such as rubber is the most important device, and there are two types of pressing rubber sleeve that relies on axial pressure to press the seal and expanding rubber sleeve that relies on radial pressure to expand the seal.

Rubber aging and anti-aging rubber introduction

One. The concept of rubber aging rubber or rubber products in the process of processing, storage and use, due to the combined effect of internal and external factors (such as heat, oxygen, ozone, metal ions, ionizing radiation, light, mechanical force, etc.) gradually decline in performance, so that the final loss of use value, this phenomenon is called rubber aging. There are many phenomena of rubber aging, such as: raw rubber will become hard, brittle or sticky when stored for a long time; Rubber film products (such as raincoats, rain cloths, etc.) will change color, become brittle and even crack after being exposed to the sun and rain. Wires and cables erected outdoors will harden, crack and even affect the absolute effect due to the action of the atmosphere.

V-shaped seal ring is actually a lip seal ring?

V-shaped seal ring is a lip seal ring with a lip, which is one of the fillers used in molding. Dongsheng sealing ring tells you that it is mainly used for reciprocating motion, for piston or pan plug rod sealing. Rarely used in rotation or as a static seal. Most of the V-shaped sealing ring is used in combination with the pressure ring and the supporting sealing ring (Figure 1 is the V-shaped sealing ring cross-sectional structure diagram). The pressure ring and the support ring are generally pressed by harder adhesive tape, but the support ring is sometimes pressed by hard plastic, and the middle seal ring is pressed by nitrile rubber sealing material. According to the use situation, some all use fabric rubber sealing ring, but also use pure sealing ring and

Seal Structure Parameters Affecting Oil Seal Performance

A good oil seal is particular, in addition to size, its sealing performance must be considered. Dongsheng seal tells you the factors that affect the sealing performance of the oil seal, including oil pressure, lip rubber performance, structural parameters, lip interference, R value (distance from the seal lip plane to the spring groove center plane), lip waist thickness, lip waist length, medium temperature, oil seal shaft speed, etc. may affect the sealing performance of the oil seal! Let us first understand the oil pressure that affects the sealing performance of the oil seal. The sealing structure parameters of the oil seal have a great influence on one aspect, which can also be said to be fatal (as shown in Figure 1. Rotary shaft lip oil

What is the tolerance of rubber oil seal size

So, what is the tolerance of the rubber seal seal? Tolerance (tolerance) The allowable variation of the actual parameter value. It also includes the parameters of physics, chemistry, electricity and other disciplines. The size of the rubber oil seal depends on the specific shaft size, including inch system, metric system, etc., and has the structural interference and hoop spring force corresponding to the shaft size.
