I am designing a 2 cylinder reciprocating air compressor that uses around 13 HP. The air compressor is currently connected to a 15 HP motor. I want to add a flywheel to my design to limit the running torque. The motor is running at 1725 RPM. Can anyone guide me the proper method to perform...
I am developing an oil-free air compressor and would like to get some feedback from anyone who has any experience in cooling. Inside of my crankcase seems to get quite warm around 250F. Was wondering if anyone has any idea how to cool the housing using natural convection. I have a fan placed...
I am working on developing a 2-stage horizontally opposed reciprocating compressor operating at 1800 RPM at 2.1 in stroke. The standard rule is to produce equal compression ratio between the two cycles but I know that is not possible especially when adding suction/discharge pressure loss and...
I have a test setup. See attached document. I need to set my pressure gage such that my water flowing out of the nozzle (.04 in orifice) will maintain .63 gal/min at 150 ft/sec. I tried the bernoulli's equation but the number seesm to high like around 260 psi. My recollection was 35 psig but...
I have a flow calculation for SCFM which requires saturation pressure (Psat)of water at ambient temperature. See attached calcuations. However the saturation pressure (Psat)curve stops at 32 degF. Is there a different curve used for saturation pressure of water at below freezing temperature...
I have a 2cy recip. air compressor directly coupled to a 1800 RPM/60 Hz motor. The air compressor is mounted on a frame which is suspended on an underfloor of a rail car. When the air compressor operates there is a significant vibration felt on the car floor.
The compressor is 350 lbs...
I am looking for a grease for cylindrical roller that can withstand 420F intermittent cycle. The roller bearing are installed on a crankshaft oscillating at 16 ft/sec. The I know there a few thickeners that provide for higher temperature resistance, oxidation etc. I just want ot make sure...
I have a connecting rod designed with a plain spherical roller bearing with both sides sealed with a shaft seal. In the con rod I have a grease fitting for applying grease once the con rod is installed on to the crankshaft. normal amount is around 20 manual pumps.
My concern is that during...
I am using a 40 threads/inch threadmill to cut a revolved groove on a flat surface. Can anybody provide a simple way to make the cut without sketching all 40 grooves.
We develop reciprocating compressors and would like to measure the oil vapor or mist for oil consumption. Is there a measuring device that can measure the amount of oil in the air?
Is it possible to create a simplified views of a complex assembly in a drawing. We have a model that is composed of 500 parts and would like to generate multiple sheets with simplified views showing step by step of the assembly.
I want to create a customized BOM on spreadsheet from an assebmly. If anybody is familiar with proe, there is a BOM icon that allows you to generate a file that can be edited using word. Can it be done as such in SW?
This is a two stage reciprocating compressor. The intercooler heads (aluminum) are bolted to the cast iron inlet heads with an aid of a aramid fiber gasket. I seem to have noticed that the gasket cannot seal the oil vapor released during compression. The pressure is 65 psi, temp= 250F. The...
