Elevator hydraulic fluid/oil water contamination – Arlington Heights, IL

We have always had a challenge when we have water contaminate the hydraulic fluid in elevator systems.  It could be from a water pipe breaking in the machine room or the pit flooding or a rec pump, pumping water back into the reservoir.  What do you do?

We had 2 issues in the last 2 months of massive water contamination of hydraulic fluid in oil reservoirs. We will discuss one that occurred in Arlington Heights, IL which we just completed the process of replacing the valve and hydraulic fluid.

What happened – We got a call that pipes where breaking in the building and one of them was in the elevator machine room.  This had occurred before so there was a pan above the drop ceiling to catch the water. However the pipe break overwhelmed the pan and it sent 50+ gallons of water onto and into the hydraulic power unit.  The entire power unit should have been replaced but the building opted to do the valve and the hydraulic fluid.

What did we do? The elevator valve was replaced, oil was replaced but there was still a lot of water in the system within the hydraulic piping and cylinder. This was caused by the elevator running during the water leak.

What happens if there is still water in the system after you replace the hydraulic fluid – If there is still water in the system eventually the valve will start to build up rust/corrosion and create leveling problems. That new valve you installed will be rusty inside and you will have trip and fall potentials. You may also experience other general shut downs from the small ports in the valves getting clogged and the pistons not moving as freely as they need to for proper operation.  If not taken care of, you can have a major safety issue on your hands.

 [Take a look at the valve blow out and notice all the small ports and moving parts that are sensitive to any foreign material including rust/corrosion]

How do you get the rest of the water out of the system? There is a wonderful device from Gorman that filters and removes water from the hydraulic fluid.  Typically when we have water contamination, we remove as much hydraulic fluid as we can, replace it and run this machine for 30-60 days until the contamination is gone. No problem we move on to the next building.

Final result – The final result was clean and clear oil ahead of schedule in less than 30 days.

Elevator water damage – Severe storms

Last week in the Chicago area we had severe storms that caused a lot of water damage to elevators.  Here are some pointers for the next time we get a lot of water/severe storms. 

1.    Do not run the elevator until you know that your pit/basement is clear from water

2.    If you suspect your elevator pit may be filled with water, call your elevator company to inspect prior to running the elevator

3.    If you do not have a sump pump, get one!

4.    If your elevator pit frequently gets water, you can install a pit switch to send the elevator away from the floor if the pit fills with water.

 Here are just a few photos of some of the issues we encountered from the last round of storms.

The first photo is from an elevator in Oak Park, IL that does not have a sump pump.  We are at this building many times a year pumping the elevator pit out.  It would be a wise investment to put a sump in the pit.  The damage it is doing to the elevator pit equipment can expensive to rectify.  Packing, hydraulic piping, rails, pit light, pit ladder, pit channels and everything else in the pit should be monitored. 

The next two photos are from a newer elevator installation in Melrose Park, IL.  It appears the sump pump failed and flooded their pit.  Since we are using Victaulic couplings those should all be replaced and the tail sheave got wet so we will have to keep an eye on that.

This is from an elevator from Chicago, IL and 3 elevator pits got flooded.  This is one of the items that was required to be replaced on one of the elevators.  Notice the gunk inside of the switch, water and electricity.   

The Life Jacket is the alternative to replacment of the elevator cylinder, right?  We had a complex that had a couple buildings flood that had Life Jackets.  Not only do we need to fix and clean your typical flood issues, we have the Life Jacket to replair/replace parts on.  

Take away – If you are looking at being better prepared for the next storm surge, call your elevator contractor and have them give you some ideas of what you can do for your specific building.   No one ever plans to have a flood, but we can help you prepare for when you do.  We can help you and your building(s) with elevator outage and expensive repairs.
