Product Introduction

WJ-242-type inhibitor jet pump mainly used in coal mine spraying inhibitor solution to prevent spontaneous combustion of coal. For coal mining goaf float coal fire retardant spray or high pressure injection cannula crowns liquid fire retardants, and flammable coal gob Inhibitor solution injection pipe and fire prevention.
Features: 1, size small and light weight. Portable and easy maintenance

Technical measures: 1. Ratio of inhibitor, be sure to follow the prescribed proportion to the ratio to ensure that the rate of resistance to meet the requirements, thus restrain the oxidation of coal self-heating phenomenon. Infusion tubing along the bottom return air trough laying, connecting pipes, require tight piping connections are not leaking. Face infusion tubing along the scraper conveyor layout, and every 50 meters, set up a three-way valve.

The ratio of the solution, to a slight stirring, until all the water-soluble inhibitor only after the spraying work. Each time before spraying, first hand piping integrity checks to ensure pipeline integrity is not leaking. Spraying process, we must avoid mechanical metal stents and other components, and their take protective measures to prevent the corrosion inhibitor mechanical equipment. Spraying work must be certified and must wear rubber gloves and raincoats. After spraying the staff required for the tub with water and injection pump for cleaning to prevent corrosion resistance of the liquid.
