Q:Single ball chloroprene rubber flexible joint, Shanghai Song Jiang rubber ball joint manufacturer where?
A tubular rubber component is composed of inner and outer layers of rubber, cord and steel ring, which is vulcanized and molded and then combined with a metal flange or a parallel joint. This product can reduce vibration and noise, and can be compensated by thermal expansion and cold contraction due to temperature changes. It is widely used in various piping systems. If I can help you, please accept it.
Q:What are the matters that should be paid attention to when installing rubber hose joint in water pump?
Know the rubber pipe joint is also called rubber joints, with vibration and noise reduction effect in the pipeline, and if used in water pump, so its main function is to prevent the suction flat and bear short time pressure, avoid water pump power and vibration and suction pipe bottom swing, the uniform flow and promotion in addition, the pump power consumption is reduced, because the rubber joint wall vertical groove, and prevent the vortex pump water, thereby improving the efficiency of water pump.
Q:Which is better for binding files with rubber tubes and cotton threads?
In fact, the most suitable binding file is the file department I twine, such units are preserved, just to have you asked, hope to adopt
Q:Toilet hose and water tank joints leaking, how to repair?
Remove the joint, wrap the tape, and press again
Q:What's the rubber sleeve of the expander?
The expansion device is also called expansion joint, expansion joint, compensator and expansion joint. The expansion device is divided into steel telescopic device, rubber telescopic device and stainless steel telescopic device according to the material. Expansion device capable of axial expansion in a certain range, the offset can overcome different axial pipe butt within a certain angle and produce, installation and convenient disassembly pipeline valve greatly, in the pipeline to allow expansion in free expansion, once over its largest expansion amount rise to limit, to ensure the safe operation of pipeline the. Mainly for the protection of the safe operation of the pipeline, has the following functions: compensating absorption pipeline axial and transverse and angular deformation; absorption equipment vibration, reduce the vibration on the impact of pipeline equipment; deformation of the pipeline, absorb seismic subsidence.
Q:How to detect the reliability of rubber hose
Low temperature bending test at low temperature: hose clamp on rigid torsion wheel diameter hose diameter 12 times, for 6 hours at a low temperature, twisted 180 degrees within 12s when the measured torque and the standard temperature measured torque ratio. Low temperature bending: hose clamped in the diameter of the hose within 12 times the torsion wheel, parked at low temperatures for 24 hours, in the 10s to reverse 180 degrees, check whether or not the internal and external plastic brittle fracture and damage. Test of low temperature brittleness measurement hose is the most simple specimen should be bent 90 degrees at low temperature, or a hose after freezing compressed 1/2 to see whether the embrittlement, another method is to use a certain weight of the heavy hammer falls freely, to see if the specimen embrittlement impact specimen.
Q:How can the hose of natural gas be connected to the water heater?
It should be noted that when the nut is installed, pay attention to each nut must have plastic or rubber soft gasket, gasket must be flat, it plays the sealing role of the joint of the pipe joint.
Q:Are the bridges, bellows and rubber tubes drawn out or are they drawn only? And the bellows are tensioned with the steel strand?
It is relatively rare, usually corrugated pipe for zinc metal corrugated pipe, the construction unit may be in order to prevent pipe blockage, when pouring concrete, the corrugated pipe with rubber tube, after pouring completed final setting, you can pull out rubber tube. Bellows need not be drawn.
Q:Natural gas can be connected to a gas cooker. Can rubber tube be used?
The user may use gas professional hose or corrugated steel pipe to connect, but the service life of the hose is 12--18 months,Commercial and construction households can and must be connected by qualified professionals
Q:High pressure hose K type joints KJR32 and KJR31.5D what is the difference between ah, please give us a answer,
K type joint has the distinction between national standard and German standard. In general, 32 of the tubes are 1 1/4 inches, and the K type mine connections are also 1 1/4, but there are two methods of KJR32 and KJR31.5D. But KJR31.5D, D means that the inner diameter is 1 1/4 inches.
