Q: The rubber is sheathed on a metal cylinder. How should they be connected?: With the combination of metal rubber is coated with adhesive before production and rubber vulcanization shaping, you can use this temporary experiment 502 geliahao for glue or adhesive, but the disadvantages of this thing with winter is not strong, the metal surface must be clean

Q: The function of rubber joint?: After installation, it can reduce the noise caused by vibration of pipes, pumps and so on, and has strong vibration absorption ability

Q: What advantages does the Parker hose have in comparison with other hydraulic hoses?: Parker hose and other hydraulic hose advantages compared to:First: from the price point of view, the price of PAKER is the most expensive industry. High popularity.Second: if from the quality point of view, the quality of stability, high degree of recognition.Third: from the point of view of use, the difference is not obvious. PAKER things match well.Fourth: strong pressure resistance, rated 400bar hose, blasting pressure can reach close to 1000ba

Q: How to detect the reliability of rubber hose: Suction flat test: in the 1min vacuum, after maintaining 10min, with diameter of 0.9 times the diameter of the hose rolled over, check the degree of collapse of the hose. Some standards used to measure the rate of change in the outer diameter of the hose to indicate the extent of deformation of the hose.

Q: What is the difference between plastic lined steel pipe and rubber lined steel pipe?: Weather resistance: the practice proves that the rubber in the harsh environment (instantaneous high temperature and direct sunlight, external strength) stable performance, so the lining hose has a strong weather resistance, weatherability and lining performance of plastic pipe as lining hose.

Q: Which is safer for stainless steel bellows and rubber tubes for gas pipelines?: Stainless steel bellows, quick fitting joint, good strength. Hose connections are end face seals, greatly improving the reliability of the seal, and some gasket material using PTFE, and its life can be consistent with the tube body, can reduce the number of maintenance or replacement.

Q: How to remove the smell of gasoline in the car?: When filling, the filling is full - when the gas is filled up, it may cause the gasoline to go down the tube into the canister so that a large amount of gasoline vapor is released from the vent of the canister.Answer: turn on the air conditioner, use the internal circulation mode (the windows should be closed, air conditioning refrigeration), so, when the car runs for a while, the gasoline will dissipate.

Q: Can high speed air flow through a rubber tube and produce static electricity?: To solve this problem, I suggest you do not focus on the voltage level, but focus on how to eliminate static electricity. For example, choose a low resistivity rubber material to ground and control the airflow humidity (if possible).If you really need to accurately grasp the size of the voltage caused by static electricity, and there is no reference to the literature, you may as well begin to study the experiment.

Q: The gas water heater uses metal pipes and rubber pipes: Metal pipes are good. Rubber tubes are easy to fall off

Q: Difference and application of rubber joint and rubber expansion joint: The utility model can be used to reduce the vibration and noise of pipelines, and can compensate for thermal expansion and cold contraction caused by temperature changes. Rubber expansion joints are used in chemical, construction, water supply and drainage systems!
