Structure Performance of Diaphragm
Composed of one or more layers of two sides coated with glue, and
also of rubber without fabric clip. According to the shape of the
separation method membrane pressure method. According to the
requirements of the production of different rubber, different
fabric diaphragm. The properties of nitrile rubber and polysulfide
rubber blends used in the diaphragm, the properties of rubber
materials used in the canvas disc diaphragm and some silicone
rubber, fluoro rubber and chloro rubber membranes developed in
recent years are described as follows.
The operating temperature and pressure range of the diaphragm
itself depends on the rubber, fabric and structure. The diaphragm
can work at -50~100 ° c and 0.4~ 0.8mpa. Fluoro rubber and silicone
rubber diaphragm can work at -80~232 ℃. Chlorol rubber diaphragm
can work under pressure of 0.4~ 0.8mpa, with good air tightness,
aging resistance, and the service life is equal to that of engine
overhaul.
Working Principle of Norgren Type Diaphragm:
The pulse solenoid valve inputs the coil of the solenoid valve into
the forward pulse signal through the wire, and the working magnetic
flux generated by the coil causes the core to pull in and open the
valve. When the forward pulse signal input is stopped, the moving
core is released, the moving core returns to the initial state
under the action of the spring force, and the closed valve has a
self-holding type, and can be maintained after the input positive
pulse is stopped or the power is turned off, and the input is
required.
The negative pulse signal can be reset; the working principle of
the pulse solenoid valve is to use the pulse of the electric
appliance to convert into mechanical pulsation, so that the
powerful energy of the pulsating gas becomes momentum, and the
large impulse is released in a short time, and the pulse is
controlled by plc. The interval should be determined based on the
rated gas pressure recovery time.
The pulse valve is controlled by the output signal of the pulse
blowing controller, and relies on the pressure changes of the two
gas chambers before and after the valve to make the rubber
diaphragm flex and deform to realize the opening and closing of the
pulse valve. The diameter of the rubber diaphragm determines the
stroke size of the rubber diaphragm and the speed of opening and
closing. The larger the diameter of the diaphragm, the larger the
stroke and the better the blowing performance.
