Q:The small hose attached to the grease gun is coarse or fine at the joint
For sealing, according to the maze principle, the smaller the pitch, the number of threads, that is, the more layers, the better the sealing effect, not easy to leak oil, significantly better than the rental thread.
Q:Diameter 127mm steel pipe, and diameter 127mm rubber hose how to connect?
A metal ring is sheathed inside the rubber tube, and the rubber tube with the metal ring is sheathed into the metal tube so that they can come into close contact with each other. In brief, the metal collar and the steel pipe hold the rubber tube in the center. I wonder if you understand. The outer diameter of the metal ring is about 111~119mm. It's hard to say how specific it is.
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?
The interface method should be carried out according to the following procedures: DN400 pipeline and below, by a man with a cotton rope hook is installed pipe socket, the other one with a long lever oblique insertion based cross baffle against the tube end of the center position, and then forced the tube slowly into after the installation of HDPE double wall corrugated pipe the pipe socket to a predetermined position; more than two sets of DN400 pipeline by hand hoist will pull in pipe section. When the interface is closed, the spanner on both sides of the pipe section shall be pulled synchronously, so that the rubber sealing ring is properly positioned and is not distorted or not falling off.
Q:The main features of Linatex rubber tube or what are the characteristics?
The main characteristics are excellent wear resistance, high impact resistance, high pressure resistance
Q:How to remove hose odor?
When rubber is peculiar, it can be scrubbed by hydrogen peroxide. After drying, the odor will disappear. Or with waste tea sent to rubber products, tea has the role of adsorption odor.
Q:What is the principle of communicating devices? What if the rubber tube is used as a connecting device to change the water for the fish?
Siphon principle: that is the principle of connected devices, plus in a closed container, the pressure on the liquid, everywhere equal. The siphon is filled with water, there is no gas, the water level of the water inlet is high, and the water outlet is closed with palm or other objects. The pressure is equal everywhere. When all are arranged, the water outlet is opened, although the atmospheric pressure on both sides is equal, the water level at the water inlet end is high and the pressure is large, and the water inflow is continuously flowed out of the water outlet.
Q:How to distinguish the true and false corrosion resistant rubber soft joint?
Method for distinguishing true and false corrosion resistant rubber soft joint:Put the rubber joint in the corrosive liquid which needs to pass. One day, 24h can see that the swelling ratio is not more than 5%!
Q:What should I pay attention to when rubber tube is in storage?
The phenomenon of natural vulcanization caused by long-term exposure to corrosive gas or prolonged exposure to sunlight is called aging of rubber. The main phenomena are increasing of self weight, volume expansion and strength reduction.
Q:Hose connector JB1885-77 what is the standard?
GB A flat joint core series hose assembly standard.
Q:How to determine the tensile strength of GB rubber joint?
The cutting of sample can be done by punching machine. When punching sample, the following points should be paid attention to.The cutting force is uniform, not too large, and with mild soap and water and clean tap water wet specimens (or tools), if a sample cut down, it should be abandoned, not to repeat the old mark for cutting.The direction of specimen cutting should be consistent with the direction of tension and the direction of rolling.
