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:Is the rubber pipe joint installed in the middle of the pipe and pump for shock absorption?
Control the noise produced by parts of machinery, equipment, and equipment. The pump foundation of the new pump house should adopt heavy weight to prevent vibration from producing noise. Vibration isolation should be set up with rubber vibration isolating pads to reduce vibration noise. Each pump unit shall be provided with a foundation to prevent resonance. Use "soft" connection as far as possible in the suction pipe and pressure pipe of the pump. Periodic maintenance problems, such as packing leakage, equipment parts loose, serious wear and tear of equipment parts, mechanical vibration and so on, should be repaired in time, thereby reducing noise.
Q:SolidWorks how do you put rubber hose on the iron pipe?
It is important to note that different materials are assigned to each other: metal and rubber. To produce engineering drawings that guide production, fill in the corresponding section lines on the cutaway surface.
Q:Is the electric water heater well connected with the metal hose?
On the other hand, the utility model can effectively avoid the frequent switch of the water heater power switch because of the two grounding. Therefore, the metal pipe connection does not meet the safety and installation specifications.
Q:How can I connect the gas tank connection hose?
The general is directly inserted into the connector on the line, if loose, can use wire twist, still feel not reliable, can go to the market to buy two hoop, screw on the line.Keep it clean.
Q:Excuse me, how can I get waterproof wires in the water?
35kV and below in low voltage cable joints if needed in the operation of the water environment, please do waterproof seal in the joints, joint can be orderly wound waterproof tape, heat shrinkable tube ends after heat shrinkable pipe shrinkage sealant, waterproof seal, installation conditions outside the FRP shell, shell insulation waterproof sealing glue perfusion. If the ordinary rain prevention, joints at both ends of the sealant after the root shrink heat shrinkable tube, heat shrinkable pipe mouth, waterproof belt, +PVC belt sealed!
Q:There are several ways to connect the built-in rubber stop
Is the cold adhesive rubber zhishuidai special cold glue, overlapped by the waterstop joints with grinder grinding section to 5~10 cm, glue can be compacted, has high strength, fast solidification has the advantages of convenient, time-saving, can meet the general engineering quality requirements.
Q:How do the rubber tubes fit into the galvanized pipe?
If the rubber tube is outside the galvanized pipe, when the rubber is ordered, the inside diameter shall be greater than the outer diameter of the galvanized pipe. If the rubber tube is inside the galvanized pipe, when the rubber is ordered, the outer diameter of the rubber pipe will be galvanized and the inner diameter of the galvanized pipe will be inside
Q:What's the difference between a vulcanized rubber tube and an intake manifold?
The inlet is the passage of air into the engine block, which leads to the cylinder. The valve is mainly composed of a channel designed on the cylinder head, and the inlet is controlled by an air inlet valve at the end of the air inlet
Q:How do I get the hose for the gas cooker?
In accordance with the relevant provisions of the country, the service life of plastic hose for two years, if used for a long time without replacement, easy gas leakage.
