In this month’s issue, which will conclude the solvent flow series, I’ll discuss valves, the devices that direct the solvent flow through the dry cleaning machine. HOW SOLVENT FLOW VALVES OPERATE The solvent flow control valves on almost every dry cleaning machine are operated by compressed air directed by a solenoid, which moves a piston […]

This month, I’ll continue on the solvent flow subject by discussing the heart of the solvent flow system, the solvent pump. The solvent pump on most drycleaning machines is a centrifugal type pump, a mechanical device designed to move solvent by employing a motor rotating a disk-like device with vanes on its surface called an

This month, we will explore solvent flow, valves, and some of the problems associated with them in the dry cleaning process. To begin with, what is solvent flow, and what is solvent? In the dry cleaning sense, a solvent is a liquid that is moved or flushed through the garments to remove dirt and debris.

The disaster for this month will be the failure of the water pump. This pump supplies coolant to the still and refrigeration condensers of the dry cleaning machine. A liquid “coolant” is forced through the coils of the condensers by this pump to cool these condensers. The coolant is water in systems using a water

I’m going to interrupt the sequence of the articles on the drying cycle of dry the cleaning machine to insert this, my annual article on cooling systems. With summer upon us, your dry cleaning machine’s cooling system will be under greater stress. It doesn’t matter if you are using a water tower, chiller, or city

This month, we will delve into identifying drying problems in DRY CLEANING machines. How can you tell if you have a drying problem? The following is a list of common symptoms associated with problems in the dry cycle: ABRUPT CHANGE IN SOLVENT CONSUMPTION Solvent consumption is often measured in the pounds cleaned per gallon or
