It can be a bad experience when your engines that are using dry vacuum pumps fail you after the pump has broken down. Break down of this type of pumps is a common problem and can halt your processing operations. The dry vacuum pumps are preferred due to the many benefits they come with as compared to other traditional vacuum pumps. The new model of the pump is economical and very efficient in executing its duties but once it experiences a problem it can fail completely. Some reasons can lead to the breakdown of these pumps entirely.
Contamination of the dry vacuum pumps is one of the primary reasons of why they fail and break down completely. When the dry air vacuum space is contaminated, it develops a problem that causes a holistic failure of this machine. The pump is made in a way that it should not be contaminated by any liquid substance making it prone to destruction after contact with a liquid. That is why it is called a dry vacuum pump since it operates in the absence of any liquid in it. One source of contamination is the substances used to wash the engine section of this pump. For instance, when using a solvent or water to clean a food processing machine, the water or the solvent may enters the dry vacuum space, when it does, it combines with the dust in the vacuum space to form a residue. This residue renders the pump ineffective and eventually it causes it to break. The amount of the residue no matter how insignificant will affect the pump in a massive way. The machine washing solvent is likely to find its way into the dry air vacuum space through the discharge port of the pump. Mostly the solvent mixes with the carbon dust inside the vacuum to form sludge that undermines the efficiency of the pump. Another source of contamination is from oil used in the pumping machine. When there is a leak in the gasket casing separating the dry vacuum pump and the oily parts, the oil may find its way into the inside of the vacuum pump. Most of the grinding parts of the pump will require lubrication.
A smaller opening can allow oil/ lubricant to soak into the dry space, and this will automatically interfere with the operation of the pump. Oil quickly saturates garter filters, and they will enable oil from the vacuum regulators to find a way into the vacuum, and that will destroy it for good. Any substances including lubricating oil, food particles, printing ink, foil particles and others can affect and wreck the pump.
Overstress of the pump
Dry vacuum pumps are also easily affected by being overworked when using them. When the pump is overworked, it overstretches beyond its ability and this causes the destruction of its parts which will eventually affect the overall performance of the pump. For instance over speeding the pump for it to give high pressure can harm the pump over time. More Top speed than the one stipulated on the pump will reduce the lifespan of the pump. The pump will be overstressed since it is being forced to work beyond its capacity. When this continually happens, the pump will stop working without offering any signs of breaking down. A rapid acceleration also has the same impact as for over speeding. When you rapidly accelerate your engine, you create a higher workload of the pump, and it is possible to destroy the inner components of the pump. Several rapid accelerations will damage the pump and render it useless with time.Wear and tear is also a common thing in any running machine. Most of the dry vacuum pumps will experience wear and tear which eventually makes them stop working after serving for a given period. Even with regular maintenance and change of vital parts of the pump, time will come when it will cease to be efficient and ultimately stop functioning.
Installation of dry vacuum pumps may sound straightforward and direct but fail to observe some important things will harm the effectiveness of the pump, and it can lead to a breakdown. When installing new vacuum pumps, it is important to ensure that all the installation requirements have been observed to make sure that the pump does not develop complications that might lead to its breakdown. It is important to ensure that the vacuum is tidy and free of any foreign materials during installation to ensure its efficiency. Blowing the pump system with compressed air is a crucial thing since it will help you get rid of any particles that might affect the functionality of the pump. You also need to remove any fragments that were left behind by the old pump to ensure that the new one occupies a clean environment. The regulator seats are primary culprits in destroying new pumps since in most cases they are left with carbon fragments in them.
How to fix the problems
Most of the above factors that lead to the breakdown of dry vacuum pumps can be prevented by taking the appropriate control measures when operating your pump in printing or food processing. Contamination is one of the biggest causes of the failure. Most of the contamination enters the vacuum through the discharge port or the drive coupling. It is vital when washing the engine to ensure these points are sealed in a bid to ensure no traces of the washing solvent entering into the vacuum. The vacuum regulator filters also allow oil to be soaked into the garter filters hence entering into the vacuum. It is necessary for you to ensure that you have them in a good state or replaced when needed to prevent the contamination problem.Over speeding the machine and rapid acceleration also harms the pump. It is important to operate the machine using the speed limits indicated on your pump to prevent it from damage. You should also endeavor to use a certified testing equipment to troubleshoot most of the problems with dry pumps. When buying a test kit, it is important to ensure that it has the capacity to troubleshoot common problems with the pressure and the vacuum itself. When making a replacement of the pump, it is important for you to ensure that it meets the standards and is of high quality. Removing the old fragments from the position you are installing the pump is an important aspect that will help you achieve optimal results from your pump.
