Understanding the Material Advantages and Limitations of Ceramic Pistons
06 January 2022
A homogeniser piston could last a couple of hundred hours. Or on the other hand, it could last 50,000 hours. Accurately picked and appropriately maintained, this crucial part can have a significant impact on your homogeniser’s total expenses. Here is what you need to know to choose the ideal piston.
Pistons play an important job in the homogeniser, compressing the item in the siphon block similarly a bike siphon creates pressure in tires. The climate where pistons operate is a demanding one, with pressure up to 630 bar and temperatures as high as 140°C.
Various factors can affect how long a piston lasts: air in the item, water/steam quality and cleaning-in-place arrangements can all diminish a piston’s lifetime by a quarter to a half. Wear or damage to the piston or pressure ring, or item related issues can abbreviate it by as much as 75%. With various materials to browse – each with its characteristics, benefits and drawbacks – how would you know which piston is ideal for your application?
Material determination is essential for the running economy of your homogeniser. There are various factors to consider. The right piston can rely upon your interaction whether you are upstream or downstream. Yet additionally, on the item, you are making. Does it have particles that make it abrasive, or is it acidic? Your running timetable ought to also be thought of. To stop the creation to change parts is exorbitant and should also be viewed as when the material is chosen. Generally speaking, the more drawn out piston lifetime you want, the more costly material has to be utilised, and there is a break-even between cost and lifetime.
In one instance, you can discover cheap pistons on the market with a long period of a couple of hundred hours. At the flip side of the scale, you have ceramic pistons which, when handled with care, will last for as long as 50,000 hours.
Choose Ceramic Pistons
Many homogeniser providers offer strong ceramic pistons. Notwithstanding, bear as a top priority that there is a variety of ceramic materials, and they vary in quality and endurance. Strong ceramic pistons have been created to have optimal wear resistance balanced with the most ideal mechanical properties. Therefore the material utilised in strong ceramic pistons is further developed than that utilised by other homogeniser brands.
Strong ceramic pistons are the Rolls Royce of pistons and will last for quite a long time with regular use. But since ceramic is weak, it should be installed appropriately and handled with care. While choosing strong ceramic pistons for another homogeniser, a bunch of stainless steel pistons is also included with the request.
The idea is that the stainless steel pistons ought to be utilised during appointing, and then the strong ceramic can be installed when charging is finished and the creation line is ready for action smoothly. The surface hardness of strong ceramic pistons is likened, on multiple occasions, to that of stainless steel pistons. They are also high wear resistance and at no danger for erosion.
