Introduction: The O-ring and retainer ring structure can withstand much more pressure than when using an O-ring alone. The Parker retaining ring can be said to supplement the pressure seal and is not itself a seal. The main reason for using the retaining ring is to reduce the clearance on the low pressure side of the O-ring and similar seals.
The Parker retainer is molded from a high-hardness rubber material into an uninterrupted ring that can be easily assembled by stretching. Since it is neither cut nor spiral, it does not cause local damage to the O-ring. It can be said that the two are a natural match.
Experiments have shown that Parker's retaining ring has a longer life and higher reliability than other types of retaining rings. The existence of the retaining ring allows the O-ring to expand the working pressure range, and there is also a small amount of lubricating oil between the two, which increases the lubrication and makes it easier for the two to get along.
The profile design of the Parker retainer ring improves the performance. This structure allows the O-ring to remain circular even under high pressure. With the appropriate groove structure, the retainer ring will not collapse and never cool into the gap. . It can be said that the retaining ring is the "optimal patron saint" of the O-ring.
The continuous structure of the Parker retaining ring means that it does not cause the O-ring to squeeze out, crumble or bite like a notched, spiral, or other discontinuous structure, reducing the O-ring because of cutting, tearing and not right The chances are therefore more reliable and extend the life of the O-ring. It can be said that the two hand in hand to whiteheads.
Parker O-Rings + Parker Retaining Rings are more eye-catching in the performance of dynamic seals, and sometimes a small change can make the problem perfect.
Mainly used for drilling water wells, monitoring wells, geothermal air condition ing hole construction, national defense projects,anti-floating anchor rod,cable anchor rod,high-pressure Rotary Jet Drilling Operations;At the same time, it is suitable for large diameter vertical hole construction in geotechnical engineer- ing such as hydropower station,railway,highway and city foundation, grouting reinforcement hole, small foundation pile holemicro-pile etc..
Construction Features:
1.The power head of drilling rig can change speed both mechanically and hydraulically. Suitable for down-hole Hammer,eel pipe, full casing and alloy rotary drilling methods.
2.Two large cylinders on the mast, lifting force up to 25 tons, eccentric with pipe drilling can be used to pull out casing,but also for small-scale non-excavation construction.
3.The rig uses inside and outside telescopic mast power head travel up to 7 meters, can drill 23 meters drill pipe at a time, reduce a time to add drill pipe, improve efficiency twice.
