Product Description:
I. Core Material Properties
The material of the pulse valve diaphragm is crucial in determining
its performance. Dahe pulse valve diaphragms mainly utilize
elastomer materials. Here are the common types and their
characteristics:
Advantages: Good oil resistance, suitable for environments with oil
mist; moderate elasticity and cost-effective.
Limitations: General temperature resistance (-20℃~120℃), weak ozone
aging resistance.
Advantages: Excellent temperature resistance (-20℃~above 200℃),
strong chemical corrosion resistance, ozone and aging resistance;
suitable for high-temperature and corrosive conditions.
Limitations: Higher cost, slightly lower elasticity compared to
nitrile rubber.
Advantages: Good weather and ozone resistance, resistance to water
vapor and weak acid corrosion; suitable for a wide temperature
range (-40℃~150℃).
Limitations: Poor oil resistance, not ideal for oil-containing
environments.
- Nitrile Butadiene Rubber (NBR):
- Fluoroelastomer (FKM):
- Ethylene Propylene Diene Monomer (EPDM):
Some advanced models may incorporate composite materials (like
rubber with fabric skeleton) to enhance tear resistance and
strength.
II. Physical and Mechanical Properties
Elasticity and Resilience: The diaphragm needs to operate swiftly under high-frequency pulse
airflow. High elasticity ensures tight sealing without leakage,
while resilience prevents deformation over time.
Tensile Strength and Tear Strength: Tensile strength resists ruptures caused by air pressure, while
tear strength prevents damage expansion, thereby extending the
diaphragm's lifespan.
Hardness: Materials commonly have a Shore hardness of 60~80A. Incorrect
hardness affects sealing and responsiveness.
Temperature Resistance: The appropriate material is chosen based on working temperatures;
for instance, fluororubber diaphragms are necessary for
high-temperature environments.
III. Working Characteristics
Sealing Performance: Precise processing ensures tight sealing between the diaphragm and
valve seat, preventing air leaks and energy wastage.
Response Speed: Quick opening and closing during pulse signal activation ensure
efficient ash cleaning.
Medium Resistance: Its wear and chemical erosion resistance help withstand moisture,
oil stains, and dust in compressed air.
Technical Parameters:
| Conventional nitrile rubber (NBR) | -20 ℃~80 ℃, Suitable For Room Temperature Drying Conditions |
| Color | Red Green Black |
| Brand | TAEHA |
| Diaphragm Material | NBR |
| Working pressure range | 0.4-0.7MPa |
| Fluororubber (FKM) | -20 ℃~200 ℃ (some Models Can Reach 260 ℃), Suitable For High
Temperature And Corrosive Environments (such As Chemical And Waste
Incineration) |
Applications:
Working Condition Adaptation: The material is selected according to the temperature of the dust
removal system, medium (oil-containing, corrosive gas, etc.), and
pulse pressure (usually 0.2~0.6MPa). For example: Corrosive
environments such as waste incineration plants and chemical
workshops → fluororubber diaphragms; Normal temperature and
non-corrosive environments such as wood processing and grain
processing → nitrile rubber diaphragms.
Service Life
Under normal working conditions, the service life of high-quality
diaphragms can reach 100,000~300,000 pulse cycles (about 1~3
years), which depends on the material, working temperature, pulse
frequency and maintenance conditions. Improper maintenance (such as
a large amount of moisture in compressed air leading to accelerated
aging of the diaphragm) will significantly shorten its service
life.
In conclusion, the core properties of Dahe pulse valve diaphragm can be
summarized as "high elasticity, strong sealing, fatigue resistance
and strong adaptability". Its performance is directly related to
the stable operation of the pulse valve and even the entire dust
removal system. When selecting, the material, size and mechanical
properties should be comprehensively considered in combination with
the actual working conditions.
