Q:What is the high and low pressure circuit of diesel engine?
Low pressure means the fuel tank to the big pump (directly driven by the engine). High pressure means the large pump to the injector
Q:There are several ways to connect the built-in rubber stop
The built-in rubber sealing belt shall be an embedded rubber water stop belt, which is also called a buried rubber water stop or a middle rubber water stop belt.
Q:Hose connector JB1885-77 what is the standard?
The reason of high pressure hose joint leakage are the following: "a" ring aging or deformation caused by leakage; the "C" ring assembly is not in place, the two plane connection or "C" uneven pressure ring is cut caused by leakage; "a" ring without compaction, the elastic deformation caused by leakage; the "C" ring spigot groove deep caused leakage. In this regard, the need to re select the same diameter and thick section "C" ring, can also be provided with a sealing plane rabbet groove of cutting or grinding, in order to reduce the rabbet groove depth, the "C" ring has enough elastic deformation (compression should be between 0.35-0.65mm).
Q:Hose wire is it? What's the function?
Hose steel wire is used for processing rubber pipe galvanized steel wire, generally divided into two kinds, one of the main skeleton material used,
Q:The main features of Linatex rubber tube or what are the characteristics?
Linatrile: silicone reinforced rubber. It has the properties of wear resistance, oil resistance, aging resistance, fatigue resistance and good air tightness.Linard HD: carbon black / silica reinforced natural / synthetic rubber, hardness 60-70IRHD. With abrasion resistance, high resilience, cutting resistance, tear resistance, impact resistance and so on.
Q:What's the difference between a silicone tube and a rubber tube?
1. Smell it with your nose. Silicone has no taste, rubber has taste.2, feel with your hands. Silicone generally better flexibility, rubber mechanical better.
Q:Is flexible rubber joint and telescopic device a kind of thing?
The utility model discloses a pipe expansion device, which is a connecting piece which is compensated by the size change caused by thermal expansion and cold contraction in the pipe connection. There are two kinds of pipe expander, one is rubber pipe telescopic device, and the other is metal pipe telescopic device.
Q:My company does high-quality rubber tube, all of the core method, and why use EPDM to do the inner tube, it is difficult to take off the core, please point out! What's the reason?
The core needs to be removed, and if it is too long, the mandrel can be divided into two sections and separated from the 2 sides
Q:HDPE double wall corrugated pipe joint shall be made of elastic sealing rubber ring and socket joint interface. What are the requirements for rubber ring joint?
When the interface is made, the inner wall of the bearing mouth is cleaned first, and the lubricant is coated on the inner wall of the socket and the rubber ring of the socket, and then the central axis of the socket face end is aligned.
Q:What are the gas hoses?
Go straight to the gas.There are 2 kinds of gas hose: one is made of black rubber thickened tube, and the other is stainless steel hose.Stainless steel hose is better, more than 10 years of life. Basically don't use it.Rubber life of 1 and a half years, 2 years later aging brittle, need to change.
