A slotter machine consists of these following parts: Base. Column. Saddle. Cross-slide. Rotating or Circular table. Ram and tool head. Ram drive. Feed drive. Bed or case: Bed or case is made up of cast iron. It supports column, tables, ram, driving mechanism, etc. the top of the bed carries horizontal ways which the worktable can transverse. Cross-slide: Cross-slide can …

Needle valves are used to restrict and control flow rates. These valves normally consist of a body with a tapered needle within a seat. To adjust the flow rate, the needle is screwed in or out via the adjustment knob. Needle valves are very common and are available in different sizes,flow rates, sensitivities, and ports. …
It is very important to properly support installed piping. Improperly supported pipe can result in the transmission of excessive noise into the frame of the building, reoccurring leaks, cracking, and, in extreme cases, buckling. Pipe should be supported by some type of commercial pipe hangers. There are a variety of systems on the market, and …
Along with hoses comes a requirement for hose connectors. There are a myriad of different types and sizes of hose connections that are perfectly suitable for compressed air. However, there are only few basic connectors that are typically used. above Figure shows two different male NPT × hose barb fittings. The combination nipple is a …
Most commercial hose assemblies are delivered with sleeve-type hose clamps. These type of clamps are inexpensive, quick to assemble, and attractive. However, they do have a couple of drawbacks. They can’t be tightened up when the assembly starts to leak, which leaves replacement as the only option. This brings to light their next problem—sleeve clamps …
Overhead retractable hoses are rather convenient in many situations. above Figure shows a retractable hose reel that may be hung from the ceiling or the wall. These reels are very useful and can be seen in almost every auto repair shop in the nation. below Figure shows a coil hose. These hoses are perfect for …
Check valves are important elements in any compression system. Singleand two-stage reciprocating compressors use a number of check valves in their systems. There is normally an input and output check valve in each pump head. These units will also incorporate an in-tank check valve, which is necessary during unload periods. Atypical in-tank check valve is …
pressure relief valves are intended for a different role than their safety counterparts. A pressure relief valve is intended to vent excess pressure from the system. These valves are, in a sense, a type of pressure regulator. When the pressure exceeds a preset level, the relief valve opens and bleeds down the system. These valves …
Safety relief valves are a critical safety device that must be used on all compression systems. These valves prevent catastrophic failure of the essential pressure equipment and piping. All receivers must be equipped with a safety relief valve that is rated to open at a pressure no higher than the maximum rating on the receiver’s …
Air tools, especially those that use air motors, will benefit from proper lubrication. This is an area of compressed air that is usually neglected, although it is responsible for causing millions of dollars of damage to air tools every year. If an air tool is lubricated properly, it will last a lifetime. On the flip …
