[Asia Pump Network News] 2CG series of high temperature gear pump referred to as 2CG high temperature pump, pumping oil in the event of failure of how to do it? Now to say high-temperature pump pumping failure solution. 2CG high temperature pump high temperature gear pump pumping failure solution Structural improvements in reducing the high temperature gear pump parts and sand contact probability and scaling probability has played a certain effect, but the pump material all the time, ubiquitous wear and tear And corrosion problems can not be eliminated at all. Various surface measures on metal materials such as plungers and pump tubes are also limited due to limitations of metal materials themselves in terms of high temperature resistance, wear resistance to sand particles, corrosion resistance and the like. In this case, choosing a new type of material that is more wear-resistant, corrosion-resistant and heat-resistant than metallic materials to manufacture the various components of the pump becomes a fundamental solution to the above pump failure problem. High-temperature pump operation, should be the oil control valve release, and then start the pump until the normal operation of empty load, and then close the return valve, gradually screw into the valve stem, increase the load, and pay attention to the pressure gauge pointer Is it normal? Oil pump stop working, the oil return valve should be slowly loosen until the pressure gauge slowly back to zero before the unloading of the pipe jack nut. It is forbidden to change the tubing or pressure gauge during load. Pump with dual-acting jack pump, dual-use oil pump with two ways at the same time is appropriate. In order to improve the service life of the high temperature gear pump, various technologies have been applied to the oil pumping high-temperature oil pump, including the structure of a long plunger short pump cylinder, the addition of a scraping sand tank, a spiral groove, a rotating plunger, O-ring seal with the end face to improve the structure and the plunger with carbon steel chrome, carbon steel spray welding, pump cylinder with carbonitriding, nitriding, boronizing, WC carbide seat and other materials Improve.

Food Grade Salt produced from Sea Salt gives a slightly different taste than Table Salt produced from Rock Salt, and is believed to be better from ordinary table salt in taste and texture. It can serve as a good substitute to regular table salt because, although it lacks sufficient iodine, it contains several other healthy minerals not found in table salt, including potassium, magnesium, calcium, and sulfate. We produce an A+ Food Grade Sea Salt was human consumption.
