Hardness testing is a precision science whose estimates are used in mechanical works. There are 4 different types of hardness testing, each with a different approach but with the same outcome. Vickers Hardness test is one of them. The system of hardness testing was designed as an alternative to the Brinell method. Whereas the Brinell process banked on ball size, test force, and sample dimension, the Vickers method derived its outcome from the ability of the indenter to penetrate the material.
How Vickers Testing Works
To get the measure of hardness of any material, the calculations are compared to how the material resists plastic deformation. What makes Vickers testing stand out is that it can be used on any material. Also, the size of the indenter does not influence the hardness of the material.
The pyramid-shaped indenter compresses the material to produce geometrical impressions. The impressions give the measurement points from which the hardness calculations derive. The Vickers hardness test is given as the Diamond Pyramid Number (DPH) or Vickers Pyramid Number (HV). The measurement scale is among the widest, which makes Vickers universal.
Reading from the Vickers test comes in xxHVyy/zz formula.
xx is the hardness number
yy is the mass of the test load while
yy is the time taken to load the mass.
HV is the material’s hardness.
The most popular Vickers Hardness test equipment is the Falcon series; 400, 450, 500, 600, and 5000.
When it comes to purchasing an industrial machine or equipment, one of the options to consider is a used one. A major reason to invest in a used generator set is to get a high quality equipment at a reasonable cost. In addition, buying one from a trusted and reputable supplier means you will be getting a reliable machine that is good value for your money.
a) Factors to consider
The first step is to identify the size and power requirements of the equipment for your needs. Some of the factors to take into consideration are the history, age, and hours clocked by the generator set. A generator that has clocked less hours will be more powerful and dependable than one that has clocked many hours. You will also want to consider its maintenance history. This is because a well maintained generator will have a longer service life and operate more efficiently. When investing in a used generator, it is also important to physically inspect it for wear and tear. You should also make sure to check on its wiring integrity, condition of its bearings and brushes, and marks among other areas. You may also want to consider what the generator was used for, and whether it was a standby generator or as the primary power source if such information is available. However, it most unlikely to find out the history of some generators since they may have been acquired through auctions or foreclosures. You may also want to consider the manufacturer. This is because some manufacturers are renowned for their high quality and long lasting brands. While taking these factors and many others into consideration may seem as a lot of work, they are necessary since you want to have peace of mind that the machine you invest in will be reliable and efficient. This is why it is even more important to deal with a trusted and reputable supplier.
b) Choosing the right supplier
Choosing the right supplier for a used generator set can make a big difference to what you will be getting. This is because generators are complex machines that need expert testing and handling to ensure they perform optimally. Since you are buying a used generator, it is also important that the machine has to be thoroughly maintained, tested, reconditioned, and repaired by certified specialists to ensure it is in optimum condition. In addition, it is also important to take into consideration the manufacturers that the supplier is dealing with. This is to ensure you can access spare parts easily should your machine encounter any issues. You should also be on the lookout for a warranty, to ensure you can make huge savings should your generator set encounter any issues. Choosing the right supplier means you will be buying from professionals to ensure you get a generator you can count on.
If you are in manufacturing you will probably work with a lot of machines and equipment. These machines need maintenance to stay productive and to help prevent faulty products who don’t pass quality inspections. TPM can help with this. You can see this as an preventative system which helps to detect which machines show defects. This basically means a strategy in which you routinely check all your machines.
If you want to maintain and improve overall equipment effectiveness (OEE) you want to be looking at three main things: performance, quality and availability. If you can map this out for all your equipment you are able to use these insights in your TPM strategy.
Usually these 8 pillars are the foundation for a strong TPM strategy:
Autonomy of maintenance
Improvement of new equipment
Process worth management
If these pillars are included in your TPM strategy you will be able to get the most performance out of your production plant. Saving you lots of money, reduction of accidents and waste.
In the current day and age there are a lot of companies who can help you map out your TPM strategy. This can be done through the usage of various apps and web platforms. For example 4 Industry provides a very user friendly platform, which can be a helping hand for implementing a solid TPM strategy. Source: https://www.4industry.io/
