About Electro Houshmand Dimand<\/span><\/h3>\n

Electro Houshmand Dimand Technical and Engineering Company was established in 2012 with the aim of consulting and implementing industrial automation projects. Our colleagues in this group have more than 15 years of experience in implementing industrial automation projects. Our view at Electro houshmand Dimand company has always been to implement new automation solutions in various automation pyramids and for our customers, and in line with this goal, we have especially turned to implementing ERP-MES-SCADA-PLC-Field systems.<\/span><\/p>\n

Maintenance and repair costs<\/strong><\/span><\/p>\n

In most industrial units, maintenance and repair costs (net) make up a large part of the total costs. In the United States, traditional net costs (labor and materials) have increased dramatically over the past ten years. By mid-1981, home appliance manufacturers had spent more than $600 million on Net. These costs increased to more than 800 billion dollars by 1991 and are expected to reach 1.2 trillion dollars by 2000. This study shows that on average, one-third of these costs, or $250 billion, are wasted due to inefficient methods being used. The American industrial community cannot accept such a level of inefficiency and hopes to compete in the world market. Because the Net costs are usually high. The reforms made in this field are short-term. Generally, the main factors that cause abnormal net factors in an industrial unit are:<\/span><\/p>\n

Downtime related to timing repairs<\/span>
\nThe usual expenses of Net labor<\/span>
\novertime<\/span>
\nRepair parts and…<\/span><\/p>\n

The main reason for such inefficiency is the lack of real information that shows the real needs of the machines, equipment and systems of the industrial unit. Most of the time, the repair time is chosen either based on statistical information or when there is a problem in the system. Until recently, the impact of net on product quality, production costs, and most importantly, profit and loss has been ignored. The general opinion was that the Net is a disaster or that it cannot do anything to improve the costs of the Net.<\/span><\/p>\n

 <\/p>\n

Working until failure<\/strong><\/span><\/p>\n

The management concept of working to failure is simple and straightforward. When a car breaks down, fix it! Such a method is very common in net machines and seems reasonable. In this way, nothing is spent until the car breaks down. In fact, it is a method that waits for a failure to occur in the device and then repairs it and acts, which Net Management does not comply with in this method. Also, this method is the most expensive net management method. Usually, in most industrial units, preventive principles (such as lubrication, machine adjustment, and other settings) can also be used and they don’t just wait for a failure to occur in the machine. But in general, in this management method, major repairs are not performed until a defect is observed in the device. The main things in this type of method are: <\/span><\/p>\n

High cost of spare parts warehouse<\/span>
\nHigh overtime costs<\/span>
\nToo much time to stop the car<\/span>
\nLow production capability<\/span>
\nOther than this method<\/span><\/p>\n

Because in this method no attempt is made to predict the net requirements. The net group must be able to react to all possible failures in the devices. For this reason, Net management wants to keep many spare parts in the warehouse, which can include the main and critical machines. Another solution that can be used is the management’s reliance on customers who can provide all the needs related to spare parts as soon as possible. Even if this work is implemented, high costs will cause a rapid decrease, increasing repair costs. Net group should be able to react quickly to all machine breakdowns.<\/span><\/p>\n

 <\/p>\n

Preventive Maintenance Management<\/strong><\/span><\/p>\n

There are many definitions of preemptive note, and they all depend on time. In other words, the score is determined based on the device’s operating time. How to implement the preventive net are very different. Sometimes they are limited and include lubrication and medium. In a complete net management program, all critical machinery from maintenance, lubrication, evaluation, and rescheduling of the net. The common feature in all these types of administrations is scheduling. In all preventive maintenance management, it is assumed that the machines wear less after a certain period. For example, a center with a horizontal two-piece chamber and a single stage, usually works for 18 months before a leaky pump needs to be replaced. In preventive net management, the pump is taken out of service after 17 months of operation and restarted. The disadvantage of this method is that the changes directly affect the normal working life of the machine. For example, the average time between failures for a pump that moves water is different from a pump that moves abrasive slurry. The normal result of using MTBF statistics in the timing of net, or harmless repairs or catastrophic failures can be. Also, you may not need to pump after 17 months. Therefore, the cost of labor and materials used for the pump is wasted. If the pump breaks before 17 months, Net must repair it. Analysis of net costs has shown that the cost of repairs performed in reactive technique (after failure) is usually three times more than the same repair performed based on schedule.<\/span><\/p>\n

 <\/p>\n

Predictive maintenance<\/strong><\/span><\/p>\n

Preventive net company, predictive net also has many definitions. Some people think that predictive maintenance is the control and monitoring of vibration of rotating machines in order to detect initial problems and start and prevent breakdowns and breakdowns. Some others think that this type of note is the monitoring of the sub-standard image<\/span><\/p>\n
