Three pairs and a search Vice rub repair (1) cylinder loaded copper inlay sleeve body, can be used to replace copper sleeve for repair. A first column group at the first piston rod diameter trimmed to uniform size, and then the outside diameter of more than 1000 # light throwing sand paper. (2) melting cylinder type square guitar body and copper jacket. (3) work surface table '(4) cylinder bore mining process technology with no material body cylinder sleeve copper materials are mostly ductile iron, the cylinder wall system state backup on a non-crystalline thin film or coating. Because the cylinder bore wall with special special this pledge, so in order to form a hard - hard fruit such as blindness friction pairing. Vice grinding cylinder bore, the cylinder bore wall of this layer off research material sheet surface table pump sales, more friction will change the structure and properties of layers to be obliterated. Friction deputy, if forced to use, it will grind dramatically as the temperature of the surface wipe rise, the plunger rod and cylinder Fasheng glued. Also in the column prepared stuffed noodle bar table a unique film with a coating containing less wear + wearable + lubricating wear group that can wipe deputy actual power or hard - soft pairing, once people become coated layer changed to it undermines the friction material deputy special best match some repair this reason, special piston pump, it is necessary to a professional repair shop. (E higher cleanliness of hydraulic oil pump service life longer A7V78DR2.0LZF00 A7V78DR2.0LZF00 A7V80MA2.0LSF00 A7V160NC2.0RSF00 A7V28EL5.1LSF00 A7V78MA5.1LSF00 A7V250NC5.1RSF00 A7V78DR2.0LZF00 According to information provided by the pump manufacturer, The average life of the bearing is 10000h, this value would need to replace the new port is an important means of hydraulic piston system is better but the quality and stability of the ship in order to ensure the normal navigation or mooring, crew and passengers to meet the needs of life, Each boat must be equipped with a certain amount of, can play a relevant role in marine mining, marine pump is one of the important auxiliary piston with a rated pressure, compact structure, high efficiency and flow and easy adjustment, are widely applied to the high pressure, high flow and flow needs to be adjusted occasions, such as hydraulic machines, construction machinery and ships in port plate with flat-screen assignment and spherical assignment in two forms when the hydraulic pump to repair the plunger by pulling out, the working chamber pressure is reduced, the outlet valve is closed, lower than the inlet pressure, inlet valve open, the liquid enters; when you push the plunger inside the studio pressure increases, the inlet valve is closed, the outlet pressure is higher than the outlet valve open service pumps, liquid discharge when using the overflow to regulate pressure and flow, with margin part of the overflow back to the original system for self-absorbing type piston pump, the hydraulic oil tank must not fall below the lower limit of the oil standard, to maintain a sufficient number of hydraulic oil hydraulic A7V58SC5.1LPF00 A7V58SC5.1RPF00 pump maintenance, crystal creating a hydraulic quality assurance (certification), the hydraulic pump from Jinan Jing Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd. (www.jnjcyy.com) (www.jnjcyy.com) Shandong Jinan, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the crystal creating hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the crystal creating hydraulic more a better future.
