Equipment Maintenance Management Software
L & 39; strategic objective of any production and utilities department is to maximize production. Machinery and equipment is managed continuously or in batches. L & 39; equipment can be complex, as in nuclear reactors or as simple as machinery tour. The goal of maximizing production is determined by the availability of equipment & 39; and its strategic objective of condition.The service & 39; maintenance of production services and utilities departments is to ensure & 39; reliability and availability of machines. The operational objectives of the service & 39; maintenance require the availability and schedule employees for work orders, maintenance d & 39; inventories for the parties, and the analysis & 39; maintenance-related problems . Equipment management software d & 39; maintenance contributes to achieving strategic and operational goals d & 39; a maintenance organization. These programs are available as stand-alone applications tailored to specific requirements, or integrated end solutions.At strategic level, the equipment & 39; MMS allows senior management to make decisions concerning the purchase of & 39; equipment by providing data and analysis & 39; costs of asset management, and providing data to the seller and & 39; analysis equipment provided by various vendors.At level of operations, l & 39; equipment MMS helps manage the programme & 39; maintenance of equipment. The software helps the prevention and predictive maintenance by & 39; analysis of historical data from previous maintenance work orders. It also helps determine the availability of equipment & 39; and duration of work. An integrated solution helps optimize inventories in determining the parties use and reorganize time.Equipment MMS is ideally suited for small and medium enterprises for which the whole & 39; integrated solutions May be very costly. The decision to install & 39; l & 39; MMS equipment should be guided by the requirements of organizations and characteristics of the software. Maintenance of equipment & 39; management software provides detailed information on & 39; equipment management software d & 39; maintenance, facility maintenance management software, & 39; maintenance of the fleet management software, the Foundation management software d & 39; maintenance and more. Maintenance of equipment & 39; management software is affiliated to the fleet maintenance software.

Free Maintenance Management Software
In the early 1990s, corporate IT costs rose irrationally, to talk, do a panacea for all the company& 39;s problems. After the dot-com bust, corporate capital expenditures significantly reduced. Currently, the expenditure on it, all through the involvement of a different approach to project management capability, and in some cases, this is an extreme workers and business consultant business case to present to the same period expenditure.during The software vendor& 39;s growth. They provide all kinds of application software industry, either as a stand-alone package or end-to-end solution. Exuberance faded after the first, the proliferation of dot-com bust. Many software vendors simply went bankrupt, leading the venture capital dried up. Total consolidated other packages to the remaining large-scale acquisitions in the ERP and large firms.the PURAIZUASETTOSORYUSHONPUROBAIDA is beyond the reach of SMEs. In addition, these solutions to justify the cost is not small and medium enterprises. Thus, small businesses stand to go ARONAPURIKESHONSOFUTOUEAPAKKEJI expensive.mms that is not the function of different life-cycle management of the assets. SMEs will choose a tight budget, if necessary, to provide application vendors. readymade as a demonstration of software applications, available on the Internet, freeware and shareware. Software vendors, some of the products will be a free download for a specific period, usually one month after any application if the customer is satisfied with the bought.freeware also be able to manage and shareware Maintenance is implemented. Freeware sample given the expectations of the customers buy the software. Thus, there is no free lunch. Equipment maintenance management software maintenance equipment to provide more information about the software, software maintenance facilities and fleet maintenance management software, software maintenance Foundation.

Maintenance of AC Electric Motors
Proper maintenance of slip ring motors is very essential in order to prevent failure resulting in damage to equipment and personal injury.
The following maintenance procedure should be performed regularly:- 1) Bearing lubrication 2) Insulation resistance check 3) Cleaning The use of unauthorized parts in the repair/maintenance of the motors, tampering by unqualified personnel, or removal or alterations of guards or conduit covers will result in dangerous conditions which can cause severe personal injury or equipment damage. All safety instructions should be followed.
1.BEARING LUBRICATION: Bearing life is assured by maintaining proper alignment, proper belt or chain tension, and good lubrication at all times. Before dispatch the motor bearings are lubricated with the proper amount and grade of grease, to provide six months of satisfactory service under normal operating conditions. For best results, grease should be compounded from a polyurea base and a good grade of petroleum oil. It should be of No.2 consistency and stabilized against oxidation. Most leading oil companies have special bearing grease that is satisfactory.
Re-lubricate bearings every six months as follows:- 1. Stop the motor. Lockout the switch 2. Thoroughly clean off pipe plugs and remove from housings
2.CLEANING: The motor exterior must be kept free of oil, dust, dirt, water, and chemicals. For fan cooled motors, it is particularly important to keep the air intake openings free of foreign material. Do not block air outlet or inlet. On non-explosion proof motors, a removable plug in the bottom of the motor bearing housing permits removal of accumulated moisture. Drain regularly. During normal operation the slip rings acquire a protective coating that contains copper oxide and graphite with absorbed water as a result of several weeks of operation. This film of coating serves as a lubricant that reduces brush wear. Operating conditions and brush grade affect the makeup and colour of this film from straw colour to jet-black. A good surface film is chocolate brown in colour. Atmospheric pollution has adverse effect on this film and its formation. Softer brushes are used for light loads and help in formation of the protective film. Hard brushes are used for heavy load and oily atmosphere.
Slip rings may be cleaned by a wiper made of several layers of hard woven canvas at the end of a wooden stick. The frequency of cleaning is decided by the atmosphere surrounding the machine. Incase of open slip rings they may be cleaned once after every 24 hours of running. Convas is not abrasive and does not damage the film. For effective cleaning wiper has to be used with sufficient pressure and use of solvents should be avoided.
3.INSULATION RESISTANCE: 1. Check insulation resistance periodically, by a megger. According to the Institute of Electrical & Electronics Engineers the insulation resistance of stator windings at 500n volts D.C after one minute, should not be less than:-
Rated voltage of machine + 1000 = Insulation resistance in Mega ohms 1000 SELECTION
For the selection of a motor for a particular application, the following points should be considered:-
1) Load torque and speed required:- Variable torque with adjustable speed Constant torque with variable speed Constant horsepower with variable speed 2) Starting torque 3) Cost 4) Efficiency 5) Type of enclosure Totally enclosed type forced air cooled (TEFC) Drip proof type 6) Temperature classification Class B motors Class F motors
