Hebei Hankai excavator boom cylinder seal replacement

Wiper seals are critical components in hydraulic and pneumatic systems, playing a vital role in ensuring the efficient operation and longevity of machinery. Typically made from elastomeric materials, wiper seals are designed to prevent contaminants from entering a system while allowing for the smooth movement of a piston or rod. Understanding the significance of these seals and their applications can help industries enhance the performance of their equipment.

So, if bell peppers are in the same scientific classification as cayenne chili pepper, why aren't bell peppers hot? It comes down to a chemical compound called capsaicin. This chemical is the sole reason why a jalapeño is spicy and bell pepper is not. A bell pepper has no capsaicin. Capsaicin attaches itself to the mucous membranes in our mouths which in turn send out the fiery sensation. That heat in your mouth (or hands) will vary greatly depending on what type of chili pepper you've eaten. Peppers are ranked by their heat, or the amount of capsaicin they contain, on a scale called the Scoville Scale. Their capsaicin concentration is given a number on the scale and it is called Scoville Heat Units. Bell peppers do not have capsaicin, so they have zero Scoville Heat Units, therefore they are way at the bottom of the Scoville scale. 

Cayenne comes from the cayenne pepper. These peppers are also part of the Capsicum annuum family, but they’re much hotter than the peppers used to make paprika (from 35,000 Scoville heat units and up).
