    Small reciprocating compressor foundation inside shipping container

    We need to mount an identical pair of 11 kW shaft power oil-free reciprocating gas compressors inside a 20ft shipping container. The manufacturer recommends a typical ACI-351 type 0.6 m thick steel reinforced concrete foundation weighing 5 times the skid weight. No specific information was...

    Noise level measurement in industrial equipment standards

    We are trying to measure the noise emitted by our products (pumps and pressure exchangers). I found some ISO and ASTM standards that describe how this is done but don't know which one is the right one to use. I am currently looking at ASTM E2202, E1014 and ISO 3704, 2204. Please advise on which...

    High speed shaft coupling

    I am in the process of designing a hydrostatic thrust bearing test stand for a small hydraulic turbine. The turbine's shaft will be driven with a VFD controlled spindle motor at roughly 25000RPM. Power should be less than 1kW. I am looking for a shaft coupling that can handle this type of speed...

    Power output of a 3x460V motor running on VFD limited at Vout=400V

    Dear motor & drive experts, I am designing a test stand using components available in the US (3x460V@60Hz)that will run in Australia(3x400V@50Hz). There are several ~10hp motors on the stand that drive centripetal pumps. The motors are controlled using VFDs, so frequency is not an issue. For...

    Availability of Carpenter electrical iron and various stainelss alloys

    I am in the process of prototyping a constant-force solenoid for a valving application. I used 1018 steel for the flux guide and 416SS for the armature until now, but would like to improve performance by using either a Carpenter electrical iron or 1002 steel for the flux guide as well as 430FR...
