We recently had a local cement manufacturer ask for Cleveland Vibrator’s assistance on clearing up flow problems in 8″, 10″, 12″ and 14″ diameter flow pipes. The accumulation had built up over several years partly to moisture contamination through worn out seals in the pipe flange connections. Cleveland Vibrator visited their facility and quoted SI Single Impact Air Knockers due to what we understood was severe blockage in the pipes. We soon found out they intended to take down the flow pipes and hammer out most of the cement lodged inside.
The customer still wanted Cleveland Vibrator to requote knowing the change in how much material was actually lodged in the pipes and think more on the lines of keeping the pipes clear in the future. Along with this request, they also wanted industrial vibrators that required the least amount of maintenance.
The main reason for this request was the mounting of the vibrators would be several floors up and wouldn’t be as easy to access once they were installed. We requoted using Cleveland Vibrator’s newest line of Turbine Vibrators. The customer reviewed and revised the quote and decided they wanted to look at RE Rotary Electric Motors after much discussion with their main maintenance folks. Since they weren’t sure if they wanted to use Three Phase Electric Motors or our Single Phase option, we had quoted them a price for both units.
The purchase order was recently placed for our Single Phase Rotary Electric Vibrators by the customer who decided these units would be the easiest to install and take care of.
The bottom line is that the amount of vibration required to keep the pipes clear had changed from the initial call, to the first visit, to the ordering point while also considering the power sources they had available. In this application, Cleveland Vibrator quoted four separate family groups of vibrators before the Single Phase Electric Motor was decided on.
They say patience is a virtue but I say that patience is a very important part of making a sale.
I would also like to add that for this application, the customer went away from the norm of using a pipe bracket assembly. We had also set the motors up on a recycling timer to operate for a specified amount of time and would shut off just by throwing a switch. With different size pipes, this method allows the customer to set the time cycles differently on each individual pipe as needed. The Rotary Electrics also have adjustable weights that can be set for a force that ranges between 0 to 100% which also helps set particular preference for individual pipes according to the severity of the clogging. With all the variables listed and conclusions drawn for the best plan of action, I think it is safe to say that this customer will not have to deal with clogging in their flow pipes for many years to come.
