Q:What does the letter of the high-pressure tubing connector mean?
The high-pressure tubing is part of high-pressure oil pipe, tubing requirements needs to bear certain pressure and fatigue strength, ensure the sealing requirements of pipeline, mainly in high pressure injection diesel engine high pressure oil pipe for car, high pressure injection and direct injection gasoline engine, oil required under the engine running in the process.
Q:Can the copper tube of GREE air conditioner be changed into rubber tube?
Unless they are specially made for air, rubber tubes for general industrial and domestic use shall not be used for connecting air conditioners. Because the refrigerant to plastic and other polymer compounds will play "swelling" role, make it soft, expansion and foaming, will make plastic and other polymer materials more easily aging and decomposition. In addition, the refrigerant pipe is not suitable for the environment of high temperature, low temperature and high pressure, and plastic pipes can not be used.
Q:What about leakage of hose joint?
Sleeve joint event Water Leakage, you may need to remove the connector and reinstall the many water pipes, it should be timely reporting the repairman to repair.
Q:What is a hose valve?
Hose valve structure is simple, easy to overhaul and replace rubber hose, with a multi-purpose valve, hose valve can also replace the gate valve, stop valve, control valve use. Manual hose valve cold resistance and good wear resistance, according to the needs of chemical production users, using a variety of recipes produced.
Q:The difference between the rubber pipe and PE pipe?
Rubber tube, this product is a rubber tube products, with oil, acid, alkali, heat, pressure and other characteristics of the transmission and attract rubber hose. Most rubber tubes are non-toxic and environmentally friendly, but some of the higher demand oil and gas pipes add flame retardants to the rubber material. The flame retardants contain toxic and harmful substances which can have a slight effect on the human body and the atmosphere. Rubber tube and characteristics; physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, conductive properties. Apply to supporting electrical appliances, electronics, furniture, equipment, toys, hardware, medical equipment, sporting goods, audio, lighting, machinery, automobiles, motorcycles, ships, aviation, and other fields.
Q:Hydraulic hose joint configuration
Well control hose connector: composed of a core rod and sheathed and connected with the sleeve is characterized in that the outer surface of the core rod and the sleeve on the surface along the circumferential direction of the corresponding is provided with at least 1 slots with each other and clasp. The utility model has the advantages of high temperature resistance, high pressure and resistance to pull out of the rubber tube, and is especially suitable for the connection hose of the oil well drilling control device.
Q:What happened to the soft rubber flat?
A slightly heated or pressurized medium will return to its original condition.
Q:What is negative pressure rubber shock proof joint? Is vacuum piping available?
Negative pressure resistant rubber shock joint is simple product requirements than the general negative pressure resistant rubber joint rubber joint is much higher, simply can't stand the pressure, for example the pipe diameter is 0.1kg pressure, rubber tube will suck flat, so with the outward pressure pipeline is completely different, negative pressure, diameter must be increase the pressure guide tube, negative pressure diversion tube also is what we usually say is a carbon steel pipe in the shock absorber rubber hose diameter, but joint diameter than the original diameter, the pressure guide tube, shock absorber rubber hose will not be sucked flat, so that the original vibration isolation and shock proof box the expansion effect is not affected, only the affected joint is slightly smaller diameter.
Q:What's the cause of a default like a general rubber product?
Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.
Q:Hydraulic hose joint dimensions
Metric plain thread1. metric screw thread with a capital M, tooth type angle 2 degrees =60 (alpha tooth type half angle);2. metric ordinary thread by pitch, coarse teeth, ordinary thread and fine teeth, two kinds of ordinary thread;2.1. coarse tooth ordinary thread mark generally does not indicate the pitch, such as M20 means coarse thread; fine tooth thread mark must indicate the pitch, such as M30 * 1.5 for fine tooth thread, in which pitch is 1.5.2.2. common thread is used for the connection and fastening between the mechanical parts, and the general thread connection is mainly made of coarse thread. The thread strength of the fine tooth thread is slightly higher than that of the same nominal diameter, and the self-locking performance is better.Mark 3. metric screw thread: M20-6H, M20 * 1.5LH-6g-40, where M represents a common thread metric, 20 nominal diameter thread is 20mm, 1.5 pitch, LH said, 6G 6H left, said thread precision grade, precision grade of internal thread uppercase, lowercase precision grade of said external thread, 40 screwing length.
