    What is Plant Maintenance?

    Plant maintenance involves strategies, methods, and practices to keep the industrial equipment functioning efficiently. It includes regular equipment evaluation to ensure efficient functioning, cleaning garbage bins and toilets. The main objective of plant maintenance is to create a productive environment for workers.

    Since there are several types of plants and factories, the methods involve in maintaining these facilities also vary. Generally, a maintenance plan includes equipment checkups, trouble-shooting, and general clean-up. Most plants have their maintenance staff. It includes workers such as on-site engineers who ensure that machines continue to function correctly. It is essential for plants that use equipment designed for assembly lines since blockage in the lines can cause severe damage.

    Why is plant maintenance necessary?

    Plant maintenance has immense significance for industries and other facilities. Following are some of the significant reasons why industries focus on plant maintenance.

    • It helps reduce forced downtime by converting unplanned downtime into planned downtime.
    • Plant maintenance has a wide range of duties, depending upon the maintenance department’s type of production and size.
    • The maintenance engineer inspects the machines, determines if it needs any alterations, and then reports to the plant manager.
    • The maintenance department works on alterations and improvements in the existing equipment to minimize breakdowns.
    • The maintenance department has a vital role in production because plant breakdown leads to severe problems, including time loss, need for overtime, temporary work shortages, spoilt materials, rescheduling of production, failure to recover overheads, weak productivity.
    • Moreover, equipment breakdown causes serious problems.
    1. If equipment stops working, the whole line comes to a halt, resulting in severe problems in the functioning of the equipment. It also blocks other lines unless the maintenance staff fixes the fault.
    2. It leads to an immediate loss in productivity and loss in revenue.
    • A neglected plant will eventually require detailed inspection, which may cause a lot of money and time. Moreover, it requires frequent examinations and alterations if the industry does not maintain it properly.

    Why do we need plant maintenance?

    Plant maintenance improves the health and safety of workers by minimizing the chances of workplace accidents. Moreover, it helps industries and factories achieve asset optimization by lessening unplanned breakdowns. Plant maintenance allows machines to perform efficiently and decreases costs associated with equipment performance. It also increases the reliability of control.

    What are the Types of Plant Maintenance?

    Plant maintenance has a broader range of types involved to maintain the machines and equipment. Here, we have the main types and sub-types of plant maintenance.

    1. Breakdown Maintenance

    In Breakdown Maintenance, the staff often repairs the equipment of machines when it breaks downs and fails to perform its normal functions properly. In such cases, maintenance staff comes into action and takes necessary measures to repair the faulty machines after inspecting.

    Breakdowns lead to poor maintenance, more spoilt material, excessive delays in production, and profit loss. Smaller plants often opt for corrective maintenance. Breakdown Maintenance requires fewer records and smaller staff.

    2. Planned Maintenance

    Maintenance staff performs planned maintenance before the equipment fails to function. The maintenance department tries to avoid machine failure and subsequent losses in planned maintenance.

    Types of Planned maintenance

    There are four types of planned maintenance: Preventive Maintenance, Predictive Maintenance, Corrective Maintenance, and Shutdown Maintenance. Here, let us discuss each type in detail.

    Preventive Maintenance

    Maintenance staff performs preventive maintenance regularly on a piece of equipment to reduce the likelihood of failing. Maintenance staff performs preventive maintenance while the equipment is functioning to avoid sudden machine or equipment breakdowns.

    Predictive Maintenance

    It helps determine the condition of in-service machines or equipment to predict the next maintenance. It promises cost savings over time-based or routine preventive maintenance because maintenance staff only performs when warranted.

    Before establishing the predictive maintenance program, factories must take the following steps:

    • Analyze the need for the equipment
    • Analyze the failure history of the equipment
    • Review all available records on defected equipment, downtime, potential regulatory fines, losses, and workplace safety
    • Establish definitions and concepts and build a case for predictive maintenance
    • Educate major industries about the techniques
    • Complete an equipment inventory
    • Evaluative the current condition of the equipment
    • Select equipment for the initial implementation of the program
    • Develop system details based on individual components and systems
    • Evaluate any existing maintenance data
    • Decide what to inspect and which systems to include
    • Define the program’s maintenance frequency, criticality, and schedule type
    • Evaluate the anticipated resources
    • Assign maintenance worker’s responsibilities and roles

    Corrective Maintenance

    Maintenance staff performs corrective maintenance to identify, isolate, and rectify a fault to restore the failed equipment, machine, or system to an operational condition within limits established for in-service operations.

    Shutdown Maintenance

    Maintenance staff performs shutdown maintenance while the equipment is not in use. Shutting down machinery is often costly. However, sometimes, shutdown maintenance is the only effective method to restore the machine in working condition because of the fault in the machines.

    What are the Benefits of Plant Maintenance?

    Plant maintenance is essential in inventory because it is essential to have correct parts for proper functioning. Moreover, it helps to enhance the efficiency and repair process when needed. Here, we have some significant benefits of plant maintenance that industries and facilities often enjoy.
