HJW-009 model of the diaphragm into neoprene, nitrile rubber, fluorine rubber, PTFE and so on, fully meet the requirements of different users. The high pressure fluid could result in serious personal injury and property damage, do not pump pressure, pump and tube system, any maintenance work, such as when to do maintenance rotor pump, the first cut off the pump inlet, open bypass pipeline system relief pressure relief mechanism so that, slowly release each pipe connection joint. Pump before and during use does not require adding any lubricant. But when reassembled after disassembly, to add appropriate grease between the central axis and copper cuff, when the diaphragm plate can also be installed inside of the plate outer coat of grease, so that both good positioning and easy sealing and demolition. To confirm that the pilot valve in place in order to tighten the bolts, otherwise it will damage the thimble; Chennai magnesium grams Shanghai Precision Machinery Co., Ltd. - diaphragm pump manufacturers for you to organize and provide more specialized information, I hope to help you! Electric diaphragm pump and electric piston high performance efficiency comparison airless spray, the surface smooth and delicate, strong adhesion, paint loss and less widely used in construction, machinery, ships, furniture and other industries. Airless sprayer into pneumatic airless sprayer, electric airless sprayer (piston) and electric airless sprayer (diaphragm), due to the pneumatic airless sprayer with a compressed air source and the need to limit using pneumatic sprayer. Now only the electric piston airless sprayer diaphragm compared with the electric airless sprayer, piston pump is a DC motor driven piston reciprocating paint inhalation, pressurized discharge, because of its exposed plunger, and the plunger in coatings, abrasive coatings under the plunger wear very quickly, once equipped with a larger diameter nozzle, which plunger reciprocating frequency increase, increased wear of the plunger, the short life of the machine. And replace the plunger is very expensive, if the voltage is not normal will be a direct result of the work of DC is not normal. In addition, due to the sharp movement back and forth, working piston pump pulsation is large, so spray instability, wall roughness on paint spray is not good enough. HJW-009 models produced Hainai magnesium diaphragm pump diaphragm pump manufacturers grams, worth your purchase! http://www.tonson.cn
