Vacuum Pump Maintenance and Precautions

Preventive maintenance refers to a maintenance method that confirms the status of equipment in advance according to the operation cycle and the equipment usage frequency.

If you ask everyone, is it better to repair after the pump is broken or to prevent it? Probably most people think preventive maintenance is good.

There are two specific modes of preventive maintenance. One is regular preventive maintenance, which is scheduled downtime maintenance according to the wearing cycle of vacuum equipment. The other is condition maintenance, which is to monitor the status of the equipment, find hidden faults or potential faults, and arrange timely maintenance in a timely manner.

Another preventive maintenance is opportunistic maintenance. That is, preventive maintenance by taking advantage of off-season production, holidays, weekends, or the opportunity of upstream and downstream downtime for maintenance. The "opportunity" of opportunistic maintenance can be an appropriate extension of the maintenance period, or an appropriate reduction of the maintenance period. This extension or shortening will not cause major damage to the equipment.

No matter what preventive maintenance method is adopted, it is the treatment before equipment failure and shutdown, in order to avoid the occurrence of failure.


Preventive Maintenance Advantages


  1. Unplanned shut down can be reduced and avoided

Most of today's enterprises organize production according to orders, and customers have very strict requirements on delivery time. In some production enterprises, just-in-time and zero inventory have become typical features. Once the vacuum equipment is shut down, it will inevitably affect certain production process, and the order will be affected, which will greatly harm the efficiency and reputation of the enterprise. Avoiding a lot of unplanned shutdown and guaranteeing on-time delivery through preventive maintenance makes a huge difference.


  1. It can reduce the chain damage of the equipment and prolong the life of the equipment

Equipment damage often starts from a part or some parts, and these parts affect other parts or parts, and it is transmitted step by step, and finally causes a big problem. Therefore, the qualitative change and damage of a certain part of the vacuum equipment will not only cause the failure of the vacuum equipment system, but also be transmitted to the equipment in the application link. Therefore, preventive maintenance can reduce or avoid minor damage, or eliminate small hidden dangers in time to avoid the expansion of the impact, and finally lead to more serious failures and damages.


  1. It can reduce maintenance costs

Of course, improper "preventive maintenance" will not only not reduce costs, but also increase costs, which we call maintenance redundancy or excess maintenance. We are talking about proper preventive maintenance that can reduce maintenance costs.

In general, planned work is 3 to 4 times more efficient than unplanned work. Because of its planned nature, preventive maintenance can study the repair plan in advance, prepare drawings, tools, spreaders and other auxiliary facilities and materials, and prepare spare parts. Once disassembled and repaired, the repair work can be completed efficiently.

On the contrary, if the vacuum equipment is already broken, people diagnose the cause in a hurry of sudden shutdown, and then search for tools, spare parts, and materials. The real maintenance time takes half a day, while the preliminary preparation may take one and a half a day to two days, and the efficiency is significantly reduced, the maintenance cost will naturally increase, the chain damage that may be caused by the subsequent maintenance will also increase the loss of replacement parts, which will increase the maintenance cost.


  1. It can reduce the risk of safety accidents

Preventive maintenance can eliminate local, minor or incipient defects in equipment, which alone can reduce the risk of safety incidents. Some serious failures of vacuum equipment could have been avoided, but due to the lack of opportunities for preventive maintenance, the risk of failures increased and eventually led to relatively large consequences. In light cases, the machine is locked, the bearings are bent, and in severe cases, the machine is destroyed.


  1. It can avoid and reduce batch quality defects or scrap

Many equipment will cause a large number of quality defects or scrapped in the process of failure. Unqualified oil content of vacuum equipment will cause food and electronic products to be scrapped. There are many such examples. Therefore, preventive maintenance can reduce or avoid batch quality deterioration or scrap during failure to some extent, and reduce economic losses caused by failure-scrap.


  1. It can make work more proactive, planned and predictable.

Opportunistic maintenance in preventive maintenance can make the production plan, work schedule and resource allocation of the factory more reasonable, more planned, and more proactive. Some factories implement night shift maintenance, weekend maintenance, and month-end maintenance, which is the opportunity to perform maintenance during the gap between the completion of production tasks.

The synchronous maintenance implemented by many steel mills is also an opportunity maintenance by using the gap between upstream and downstream shutdowns.

Beverage, refrigerator, freezer, and air-conditioning manufacturers have tight production tasks in summer and light winters, so preventive maintenance can be arranged in winter as much as possible.

Cigarette industry winter tasks is tight, it is slightly easier in summer, and the opportunity maintenance can be arranged in midsummer.

When the maintenance task of the enterprise is tight, the maintenance gap can be adjusted appropriately so as to effectively utilize the maintenance manpower and facility resources. In conclusion, opportunistic preventive maintenance allows for more flexible scheduling of work.


  1. Reduce the risk of environmental damage

As well as reducing safety injuries, preventive maintenance can effectively reduce the risk of environmental damage. Equipment, especially involving toxic gases, leakage of liquid equipment will cause environmental damage. Equipment noise will also pollute the environment. The water treatment and air purification equipment in the enterprise is directly related to the impact on the discharge environment.


  1. Conducive to energy saving and consumption reduction

Poorly functioning equipment tends to increase friction and energy consumption. Preventive maintenance can ensure the smooth and stable operation of equipment and facilities, effectively reduce energy consumption, and maintain the energy-saving effect of equipment.
