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?
The principle of communicating devices can be explained by liquid pressure. If the same liquid is contained in a U glass tube, a small liquid AB is conceived at the center of the bottom of the communicating device. If the liquid is stationary, it does not flow. The pressure of the liquid in the left tube toward the right side of the liquid AB must be equal to the pressure of the liquid in the right tube toward the left of the liquid AB. Because in the communicating vessel is filled with a liquid, the same two liquid column density, according to the formula of P= P GH liquid pressure that only when both sides is equal to the height of liquid column, the liquid column is equal to the pressure on both sides of the liquid film AB. Therefore, in the case of no flow of liquid, the liquid level in each vessel of the communicating device shall be kept flat. (ideal model method) the connecting device is characterized in that the liquid level in each container is flat only when the same liquid is contained in the container. If the container is tilted, the liquid in each container is about to begin to flow. One end of the liquid column flows to the lower end of the liquid column and stops flowing until the liquid level in each container is normal. As with rubber tube two glass tubes connected together in container with a liquid, which will be a fixed tube, the other tube up and down or tilt, can see the two tube level in stationary phase remained flat. The connecting device is provided with the same liquid, but the pressure on the liquid surface is unequal, and the pressure difference of the liquid surface is equal to the pressure difference produced by the liquid level difference of the two container of the communicating device.
Q:Is it feasible to use rubber material, middle canvas layer and outer rubber material in PVC rubber tube?
Improvement measures: 1, adjust the process, plastic material in place; mixing rubber plastic stability; vulcanized rubbing with low temperature long time vulcanization; 2, test cloth in curing temperature shrinkage coefficient is too big, consider changing cloth;
Q:Difference and application of rubber joint and rubber expansion joint
Rubber expansion joint is also called rubber joint, flexible rubber joints, rubber soft connection, soft joints, rubber expansion joint is formed by high temperature plastic rubber, rubber expansion joint and makes full use of the characteristics of rubber elasticity, high resistance, medium resistance etc..
Q:What material is the rubber joint used in the desulfurization pipeline? What's the difference?
Three yuan EPDM rubber joint can be used, PN4-6 is no problem. Generally, the desulfurization pipeline is weak acid base,
Q:Between the two flanges in the middle of the rubber pipe, what is the name of the connection?
The product is mainly composed of inner and outer rubber layer, cord fabric and steel wire ring. It is formed by vulcanizing with metal flange at high temperature and high pressure
Q:The principle of the common bicycle valve
When the air pump does not inflate, the elastic rubber tube is tightened to cover the small holes on the side, so that the air can not flow back from the tyre.
Q:What are the categories of hose?
A rubber hose products structure: hose cloth; woven hose (fiber braided hose, steel wire braided hose); winding hose (fiber winding hose, hose winding wire); knitted hose, hose and other circular weaving hose (rubber hose, rubber and plastic composite hose and hose, drilling hose, etc.).
Q:M40 and M50, and then the hose is 2 "what does the box connection mean?"
This should be called joints, hose connectors or joints or the traditional water tower.
Q:What glue can glue rubber tube?
Location: in the face and then drop a little sticky rubber JL-330 iron speedglue, immediately bonded, and keep to the hardening, hardening time ranging from a few seconds. About 30 minutes to reach practical strength, 24 hours after the maximum intensity.
Q:Three yuan ethylene propylene rubber hose, hydraulic oil and oil?
Second, according to the principle of similarity and compatibility, non polar matter is compatible with non-polar polarity, and polarity is compatible with polarity. Therefore, three yuan ethylene propylene rubber is not resistant to oil, as regards hydraulic oil, to see what kind of it belongs to.
