MOS and POS stand for: * MOS: Maintenance Override Switch * POS: Process Override Switch Both are switches used to temporarily bypass the normal operation of a control system, but for different purposes: 🔧 MOS (Maintenance Override Switch): * Used during maintenance activities on equipment. * Allows technicians to bypass a safety interlock or control signal, such as a level switch, for tasks like cleaning or replacing the equipment. * Bypassing a safety interlock should be done with caution and following established procedures to ensure safety. * Example: While cleaning a pressure vessel, an MOS might be used to bypass the low-level switch that would normally shut down the process if the level falls below a safe minimum. 🔄 POS (Process Override Switch): * Used during plant startup or shutdown. * Allows operators to temporarily override a control signal, such as a pressure switch, that might prevent the equipment from starting or shutting down properly. * Bypassing a control signal can disrupt the normal process and should only be done when necessary and following safe operating procedures. * Example: During the startup of a pump, a POS might be used to override a high-pressure switch that would prevent the pump from starting until the pressure in the system has decreased. It's important to remember that using both MOS and POS should be done with caution and only when absolutely necessary. Always follow proper safety procedures and obtain authorization before using either switch. #OilAndGas #SafetyFirst #EquipmentMaintenance #processcontrol

Petroleum Refining & Gas Processing engineer | Process Design and Optimisation | Process Safety (HAZID/HAZOP)
Title: A Comprehensive Guide to C Series Compressor: Sections, Components, Function, Operation, and Troubleshooting Sections of C Series Compressor: 1. Compression Section:This section is responsible for compressing the refrigerant gas. It typically consists of cylinders, pistons, valves, and a crankshaft. 2. Motor Section: The motor section houses the electric motor responsible for driving the compressor. It ensures proper rotation of the crankshaft to drive the compression process. 3. Cooling Section: Compressors generate heat during operation, and the cooling section is essential for dissipating this heat to maintain optimal operating temperatures. It often includes fans, heat exchangers, and cooling fins. Components of C Series Compressor: 1. Cylinders and Pistons: These components play a crucial role in the compression process. Pistons move up and down within cylinders, compressing the refrigerant gas. 2. Valves: Intake and discharge valves regulate the flow of refrigerant gas into and out of the compression chamber, ensuring efficient operation. 3.Crankshaft:The crankshaft converts the rotational motion of the motor into linear motion, which drives the pistons within the cylinders. 4. Electric Motor :The motor provides the necessary power to drive the compressor, typically through an electrical connection. Function and Operation: The C Series compressor operates on the principle of vapor compression refrigeration. During operation, the motor drives the crankshaft, causing the pistons to move within the cylinders. As the pistons move, they compress the refrigerant gas, increasing its pressure and temperature. The compressed gas then flows through the discharge valve into the refrigeration system, where it releases heat and cools down before returning to the compressor as a low-pressure gas. This cycle continues to provide continuous refrigeration. Troubleshooting: 1. **Lack of Cooling:** If the compressor fails to provide sufficient cooling, check for obstructions in the cooling section, such as debris or dirt accumulation on the cooling fins. Ensure that the fans are functioning correctly and that the refrigerant gas levels are adequate. 2. **Abnormal Noise:** Unusual noises during operation can indicate issues with the compression section, such as worn-out pistons or faulty valves. Inspect these components for damage and replace them if necessary. 3. Motor Malfunction:If the compressor fails to start or experiences intermittent motor operation, inspect the electrical connections and the motor itself for signs of damage or wear. Replace any faulty components to restore proper operation.

International Trainer, Motivational Speaker, Corporate Coach, Conducted over 750 Training sessions in 7 destinations of the World.
Yesterday, on May 24th, during the online maintenance management course, on the 9th day, we emphasized that when you take equipment for service, you inadvertently apply various maintenance types. These include time-based maintenance, predictive maintenance (such as using an insulation tester to check cables or motors), run-to-failure maintenance (like replacing a capacitor after 5 years even if it's not defective, as these cannot be maintained), and condition-based maintenance (where real-time readings are checked after service while the machine is running to assess performance) and Finally, failure-finding maintenance involves removing a Miniature Circuit Breaker (MCB) from the electrical panel and checking it in the workshop using the catalog to identify the tripping curve. In conclusion, lack of maintenance will increase your energy bill.

Highly Dedicated Project Management Professional | Project Oversight | Renewable Energy | Hydrogen | Sustainability in Manufacturing
Your maintenance plan is almost done, how to plan your materials and inventory for O&M? Many classifications for inventory management are used, one of the commonly used ones is ABC Analysis: ✔️ The classification at which spare parts are divided into three categories based on their cost and demand. Category A 🔺High cost and low demand but critical🔥 E.g. Gas ompressor shaft Weighs 60-80% from total inventory Category B 🔹Medium demand and cost E.g. Bearing Up to 25% of you total cost Category C 🔘 Medium to high demand low cost (consumables) 5 to 15% from total cost Some organizations keep all inventory within its premises, some others rely on suppliers services to maintain and support selected spares, 🔆Whats the best practice? هناك طرق متعدده لتصنيف المواد وادارة المخزون لضمان جودة التشغيل والصيانه في المصانع. واحده من مذه الطرق هي تحليل ABC تصنف فيه المواد الى ٣ اصناف حسب التكلفه والاحتياج، تقوم المنشأه بتخز��ن المواد بالمستودع وايضا يمكن ان تبقيها في مستودع المورد وتعتمد على اتفاقيات #bestpractice #maintenance #reliability #project Ref: (Gulati, Ramesh.

Refrigeration Maintenance Contracts - The ICE way On the first maintenance visit each piece of equipment will receive an ICE asset tag, with a unique asset code. Our engineers then create a full equipment asset list for your site, detailing refrigerant type and quantity, and calculate the CO2 equivalent weight. A maintenance check sheet is selected and completed based on the type of equipment being serviced, as we don’t use one generic check sheet for all equipment. A report is completed via software on the engineers’ mobile devices for each piece of equipment and given an overall traffic light rating based on condition. Following the visit, you receive a digital pack containing a report for each asset detailing any work carried out, any work or repairs recommended, a leak check certificate and a full refrigerant asset list. If your current contract is coming to an end and you would like a free of charge site survey/audit or alternative proposal then get in touch.

BEST PRACTICES in EQUIPMENT SELECTION: Air Pressure Drop As engineered-systems equipment reps, our clients rely on us to make proper selections for their applications. We've been doing it successfully for decades, for everything from finned-tube to complex custom air handlers and refrigeration systems. HVAC system design often focuses on a proper initial operating condition of the system. Understanding and planning for changes that occur as the system ages is critical to selecting equipment that will operate properly over the long haul. There are two important, and easily adjusted, airside variables that are often short-changed at the time of selection: filter pressure drop and airside fouling factor. I have seen many a selection where the filter pressure drop used is the initial (or lower) APD of the filter. The final APD of the filter can be 3x or more higher than the starting APD, and that can spell disaster for fan and motor performance if it's not accounted for at the onset. Airside fouling factor is a number that accounts for the film (dirt, biofilm, corrosion) that can build up on the heat exchanger over time. A paper published 20 years ago by Purdue's Mechanical Engineering department showed that when coils were loading with dust, the pressure drop fouling factor increases continuously, and was dramatically worse the lower the efficiency of the filter and the amount of bypass. Their conclusions make perfect sense to anyone who has seen old air handler coils. Dirty cooling coils can experience fouling factors on the range of 0.001 sq ft-°F-hr/Btu, which is the the fouling-factor value at the top of the range considered by AHRI Standard 550/590; it represents a dirty coil. Many a selection is made with the airside fouling factor set at 0.0000, which is equivalent to the magical "frictionless plane" from our old physics classes. It's important to consider future-proofing your selections as much as realistically possible: select coils with cleanable fin spacing, select low pressure-drop air cleaners that minimize bypass, utilize UV lights on the downstream side of cooling coils to reduce biofilm, and add pressure-drop sensors with alarms and/or monitoring to help the owner keep equipment well-maintained. And make sure you request end-life filter APD and airside fouling factor selections when making critical equipment selections: a few extra minutes on the computer beats dozens of call-backs due to preventable performance problems.
