Connect the multimeter to the output lead.
Unscrew the screw on the top of the controller.
The positive and negative pressure difference is added to 0.15 MPa, which can be read from a standard pressure gauge.
Loosen the set screws.
Use a flat-blade wrench and turn the set point clockwise to adjust the hexagonal groove in the screw so that the set value will become smaller until the switch contact switches at 0.15 MPa.
Adjust the pressure of the calibration table back and forth at 0.6MPa, and check whether the pressure is 0.15Mpa. This value is the lower switching value to be set. Its corresponding upper switching value is between 0.16-0.17MPa.
Tighten the set screws.
Commissioning is complete.
The above is the introduction of explosion-proof switch installation method, we can find out. Explosion-proof switch is mainly used in metallurgy, chemical, petroleum, steel, machinery, refrigeration equipment, refrigeration equipment, water pump differential pressure control, low water level protection differential pressure control, power plant, cement, food, shipbuilding and other industries of gas, steam and water, Oil pressure and other liquid pressure equipment and other industrial equipment supporting agencies, pressure monitoring, alarm, interlock protection, to achieve two automatic control.

Square Ductile Gratings

Square Ductile Gratings are a type of grating system that is commonly used in various industries and applications. These gratings are designed to provide a strong and durable solution for platforms, walkways, and other areas where heavy loads and frequent foot traffic are expected. In this article, we will explore the characteristics, features, and benefits of square ductile gratings in detail.

Square ductile gratings are typically made from ductile iron, a type of cast iron that has been treated with a small amount of magnesium to enhance its strength and toughness. This material is known for its high resistance to impact, fatigue, and corrosion, making it ideal for outdoor and industrial environments. The ductile iron construction also allows for a higher load-bearing capacity compared to other materials, such as steel or aluminum.

One of the key features of square ductile gratings is their square-shaped openings. These openings are designed to allow for the efficient drainage of water, debris, and other materials, reducing the risk of slips and falls. The square shape also provides a stable and secure surface for walking or standing, even in wet or slippery conditions. Additionally, the openings allow for ample airflow, which can be beneficial in applications where ventilation is required.

Square ductile gratings are available in a variety of sizes and load ratings to suit different requirements. The load rating refers to the maximum weight that the grating can safely support without deformation or failure. This makes it crucial to choose the appropriate load rating based on the expected load and usage of the grating. Higher load ratings are typically achieved by increasing the thickness and depth of the grating bars.

In addition to their strength and durability, square ductile gratings also offer several other benefits. One of the main advantages is their ease of installation. These gratings are often supplied in pre-fabricated panels, which can be quickly and easily installed using standard fixing method.


Another benefit of square ductile gratings is their low maintenance requirements. The ductile iron material is resistant to rust and corrosion, reducing the need for regular painting or coating. Additionally, the square-shaped openings allow for easy cleaning, as debris and dirt can be easily swept or hosed off the surface. This can save both time and money on maintenance and cleaning efforts.

Square ductile gratings are also highly versatile and can be used in a wide range of applications. They are commonly used in industrial settings, such as oil refineries, chemical plants, and power stations, where heavy loads and harsh conditions are present. They are also suitable for commercial applications, such as pedestrian walkways, ramps, and platforms. The strong and durable nature of these gratings makes them ideal for areas with high foot traffic, such as airports, train stations, and shopping centers.

In conclusion, square ductile gratings are a reliable and robust solution for various industrial and commercial applications. Their ductile iron construction provides strength, durability, and resistance to impact and corrosion. The square-shaped openings allow for efficient drainage and airflow, while also providing a stable and secure surface. With their ease of installation and low maintenance requirements, square ductile gratings offer a cost-effective and versatile solution for many industries.
