Hydraulic pressure & temperature risks

Hydraulic pressure & temperature risks

Hydraulic pressure & temperature risks

(OP)
What temperature does hydraulic oil embed into the skin (when does is become a hazard)?  Also, what pressure does hydraulic oil burn the skin (needing more than first aid)?  I looked in all the specs and standards that I could find, but an actually temperature range was not defined.  Can anyone point me in the right direction?

RE: Hydraulic pressure & temperature risks

This link states 100psi, however, I though there was a 15psi limit imposed by OSHA, but I didn't find it on first google.  as far temperature that causes burns, google search indicates it depends on your lawer. (hot coffe cases found) http://www.cmki.org/LMHS/Chapters/13i-Injection.htm

RE: Hydraulic pressure & temperature risks

I have an "old" copy of NFPA/JIC T2.24.1-1990.

Section 6.7.1
"Under continuous operation at rated conditions, the bulk hydraulic fluid temperature measured in the system reservoir at the closest proximity to the pump inlet shall not exceed 54 degrees C when operating with mineral based fluids and 49 degrees C when operating with fire resistant or high water content hydraulic fluids."

Oil temperature should be held to 130 to 140 degrees F in an industrial system, but on moving equipment where heat removal is difficult, the temperature is sometimes allowed to reach 200 degrees F although this is not desirable as it is destructive to the oil and to components.

White Paper – Your Construction ERP RFP Checklist
Selecting business software for a medium to enterprise-sized construction concern is extremely challenging in large part because most enterprise resource planning (ERP) suites originated in the world of repetitive manufacturing and are therefore a poor fit for a project and asset-centric business. However, midsize to large contractors need the predictable, auditable processes that ERP delivers. Download Now
