How Is The Way That A Pneumatic Conveying System Operated Related To The Material And Its Attainment?
A pneumatic conveying system basically is a method by which hot bulk materials or powdery powders are either transported or conveyed via a fluid-based gas to a distant destination using a circulating pump. The materials being moved or conveyed can be air, water or both. The materials being moved or conveyed either are heated using electrical or hydraulic machinery, or by mechanical means such as rollers or casters. When a pneumatic system is used, it has the ability to deliver very fast delivery times, especially when the system and machinery are operating at maximum capacity. However, these systems often fail for one reason or another and then require repair.
Reasons to go for pneumatic conveying system
There are several common reasons why pneumatic conveying systems fail and they include: a lack of adequate pressure, a lack of a properly functioning pump, or a build up of dust or debris in the system. These failures result from the mechanical design of the system failing at the point where the flow direction and the pressure change; this is typically located in a pumping station. Another common reason for a pump failure or other problem is poor maintenance of the machinery. This includes using grease or oil when not necessary, or changing the oil or grease in the correct way to avoid leaks and corrosion.
One of the most common locations for a pneumatic conveying system to fail is in piping; oftentimes this is due to incorrect placement of the line or a buildup of blockages. Some pipes are placed inside the wall of a building or other structure and fail because of the pressure they exert against the walls of the structure itself, while others are placed on or alongside an existing or pre-existing structure such as an asphalt parking lot or an overbanked road. Pipes that are placed inside a structure fail because they are not strong enough to withstand the pressures they are subject to. This pressure causes buckling, bending and eventually snapping of the pipe. Common locations for these failures include gas lines, refrigeration lines, storm water drainage pipes, sanitary sewer lines, natural gas and propane lines, telephone utility lines and private residential sewer lines.
A third common reason pneumatic conveying systems work incorrectly is because they use improperly designed powders. The wrong type of powder or filler will stop flowing before it ever gets to the pumping station or the receiving area. The two types of powders commonly used in the industry are suitable fillers and suitable lubricants. Although the industry standards call for suitable lubricants, many companies substitute suitable fillers because they believe the new lubricants are less expensive. While it may seem cheaper, it is often financially expedient to use unsuitable lubricants, resulting in unnecessary downtime and increased repair costs.
