Feedback from pressure switches in reliable control systems.

Feedback from pressure switches in reliable control systems.

Explaining two frequently asked questions regarding the integration of valves into safety systems!

The typical application of the DM2 series C valve is to shut off the compressed air energy supplied from the air inlet while dissipating the energy on the secondary side of the valve. When safety events occur, such as the opening of guard doors or the operation of emergency stop devices, this valve dissipates the downstream pressure of the system and removes the pneumatic energy. There are two common questions regarding the integration of this valve into safety systems. "Why does the valve not have two feedback switches for monitoring by the safety system?" "How should the downstream pressure be monitored by the safety system?" To answer these two questions, some information about the valve's function is necessary. We provide a detailed explanation in this document, so please take a look. *For more details, please refer to the PDF document or feel free to contact us.*

[Data] Safety + Machine Operating Time = Money

[Data] Safety + Machine Operating Time = Money

Lockout/tagout-related standards help improve productivity and profitability while prioritizing safety.

Many people consider compliance with safety standards to be a cost without benefits. However, lockout/tagout-related safety standards can help promote safety while improving productivity. Safety and production uptime are equivalent to money. Single Point Lockout (SPLO) is a method that reduces the number of lockout locations, and by incorporating SPLO, compliance with standards is achieved, resulting in real savings and benefits. This document provides a detailed explanation, so please take a moment to read it.

[Example] A method for resolving cement material clogging, more effective than a blaster.

[Example] A method for resolving cement material clogging, more effective than a blaster.

By bursting sequence-controlled compressed air at intervals of 10 to 15 seconds, the materials are lifted off the wall and stirred, completely solving the material clogging problem!

**Problem** In cement manufacturing, crushed stone is mixed with iron ore and fly ash and melted in a kiln at a high temperature of 2700 degrees. One of the by-products of this process is clinker. Clinker consists of gray, marble-sized balls that pass through a cooler, are crushed, and mixed with other materials to be used as a binder in cement. Clinker is sticky at high temperatures and prone to wear, making it easy to adhere to containers and chutes. Heidelberg Cement attempted to blast the blocks with two air blasters, but it was unsuccessful. To solve this problem, human intervention was still necessary. "We were breaking up the material in the tube with long sticks." **Solution** Heidelberg Cement needed a more reliable material flow activation device that could eliminate all clumps of material. *For more details, please refer to the PDF document or feel free to contact us.*

Full of information such as international standards to refer to, methods for risk assessment, oil and pneumatic risk reduction measures for various applications, and equipment selection flowcharts.

"Machine safety" refers to the efforts to avoid accidents and disasters that may occur when using machinery through machine design. Even if there are operator mistakes, misoperations, or failures of the machinery itself, if the design and equipment are implemented with these risks in mind, it becomes possible to reduce the risk of accidents. ~The Importance of Risk Assessment for Pneumatic and Hydraulic Equipment~ In production facilities and various machines, pneumatic and hydraulic energy is widely used in addition to electricity. For example, even if electrical control equipment is established for safety, if the final drive device, which is the pneumatic or hydraulic equipment, breaks down, the facility may become unsafe. This document introduces international standards to refer to for preventing machine disasters in hydraulic and pneumatic equipment, methods for risk assessment, key points for risk evaluation, and specific measures for reducing pneumatic and hydraulic risks, all in a substantial 96-page volume. [Contents (Excerpt)] ■ International standards related to pneumatic and hydraulic safety ■ Safety construction process ■ Risk assessment ■ Selection of safety functions ■ Selection of pneumatic safety valves ■ Selection of hydraulic safety functions ■ Safety design ■ Design verification And more.

[Case] Resolving cement blockage with air sweep.

[Case] Resolving cement blockage with air sweep.

In the Philippines, where humidity is very high, cement materials that had solidified due to moisture in the air were being knocked out of silos, but that is no longer necessary!

Air Sweep instantly releases compressed air in a 360-degree direction along the inner walls of the material container, powerfully resolving stubborn powder blockages. This case introduces the resolution of blockage issues at a cement plant in the very humid Philippines. Due to the high moisture content in the air, the cement material was solidifying, leading to the introduction of knockers and vibrators; however, workers ultimately had to "hammer the silo." As a countermeasure, 12 units of the Air Sweep model VA-51 were installed. The blockage problem that had troubled the company for years was resolved in just four days! Additionally, the "noise" issue associated with knockers and vibrators was also eliminated. This customer plans to expand the energy-efficient Air Sweep to other plants as well.

Full of information such as international standards, methods and precautions for risk assessment, examples of risks associated with hydraulic and pneumatic equipment, and a selection flowchart for hydraulic and pneumatic equipment.

Many labor accidents, such as those involving machinery entrapment, occur not during operation but during maintenance or adjustment of the machinery. During maintenance or adjustment, safety covers may be removed, and if the machinery operates unexpectedly, workers are exposed to significant danger. Risk assessments need to consider not only operational scenarios but also maintenance and adjustment situations. In addition to electricity, "hydraulic and pneumatic energy" is widely used, and risk assessments must take all forms of energy into account. This document presents international standards that serve as a guide for reducing the risk of labor accidents caused by hydraulic and pneumatic energy, as well as methods for risk assessment and key points for risk evaluation, all in a substantial volume of 96 pages. 【What is machine safety?】 It is the concept of reducing the risk of labor accidents (machine accidents) by designing equipment that anticipates risks from "operator mistakes or misoperations" and "failures of the machinery itself." 【Contents included】 ■ International standards related to hydraulic and pneumatic safety ■ Safety construction process ■ Risk assessment ■ Selection of safety functions ■ Selection of pneumatic safety valves ■ Selection of hydraulic safety functions ■ Safety design ■ Design verification, etc.
