Engineering hydraulic cylinder manufacturers, Lu Hydraulic (certified), hydraulic cylinders provided by the Texas Lu manufacturers of hydraulic equipment plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is specialized in "jacks, electric pumps, hand pumps, cylinders," the business, the company adhering to the "honesty, hard service" concept, to provide you with the highest quality products and service. Welcome to inquire! Contact: Lu Jingli. If the fuel tank vent valve is set, you can look at pipe joints loose, and then do a few actions to exhaust. But pay attention to fuel injection, if the cylinder pressure joints, the selection pressure joints are more secure because it is easy to operate, in general, exhaust the best high, so the effect is better. If neither of the cylinder, exhaust operation can be performed, the specific operation is: let the piston rod moves to one direction, pause a few times, and then it moves to the other direction, then pause some time, so repeatedly, you can drain the air in the cylinder. Hydraulic cylinder is a hydraulic system, the most important manufacturers of hydraulic actuators, Shandong, hydraulic energy into mechanical energy it, and compatible with a variety of transmission, complete a variety of mechanical motion. Simple hydraulic cylinder has a structure, output power, stable and reliable performance, easy maintenance, wide range of applications and so on. When servicing hydraulic cylinder, the first to be cleaned and polished hydraulic cylinder manufacturers, with cotton wool dipped in acetone or ethanol will scratch the site cleaned and polished. Directly without first cleaning and polishing, make oil immersion cylinder, causing the adhesive is not strong Chongqing hydraulic cylinder manufacturers, or even fall off. When the first crushing grinding parts polished to a higher plane of section plane below to prevent scratching the plunger again, and then needle files will scratch the oil trenches, foreign body excised, and finally with rotary file will entire scratched surface roughening. Dry cleaning and heating, Polished good scratch on the surface, wipe clean with acetone. Then use hot air to dry the moisture or halogen lamp Changsha hydraulic cylinder manufacturers, but also treat the repaired surface to warm up, especially in the case of room temperature below 15 ℃, and must be treated to repair the surface to warm up. Less.
