Shandong Sheng Machinery Co., Ltd specializes in producing various types of brick, brick machine, brick machine, hollow brick, brick pavement and other equipment of the old brick factory.
        With liquid PRESS increased automation, naturally causing air pollution, the reason is after the hydraulic oil into the air, due to the volume and pressure is inversely proportional to the gas, so as the load changes, the movement of the actuator will be affected ; after plugging the inlet filter, suction resistance of hydraulic oil greatly increased, can cause cavitation, vibration and noise; air oxidation and also enables the element hydraulic oil lubrication properties lost; especially under ambient conditions of high temperature and pressure, air can easily cause oxidative deterioration of hydraulic oil flow resistance increases, causing the actuator is not normal, another deterioration of hydraulic oil can also generate harmful substances will corrode metal parts.
Liquid PRESS solid particle contamination. Speaking of solid contamination, the primary factor to understand solid - solid particles. Solid particles including dust, welding slag, rust sheet, and metal powder.
Liquid PRESS mixed with the hydraulic oil and the flow of oil and throughout the hydraulic system, when the valve body through which the dirt will slide to fill the gap, resulting in movement of the spool valve bradykinesia or interrupted. Second hydraulic oil containing solid particles is similar to an abrasive used in the metal working surface, when it is through the pump, the cylinder and the valve, will increase the wear of the friction, generate new pollution particles, will greatly reduce the lifetime of the elements a serious threat to the normal operation of the hydraulic system.
Liquid PRESS running power is the hydraulic oil, hydraulic oil contamination pathway oil mixed solids mainly due to the fuel tank, pipe fittings after processing residue is not clean, or not completely before installing the rust caused by pickling. In addition, solid particles such as dust but also with air mixed with oil.
Hydraulic oil mixed with air brick is mainly due to pipe fittings, hydraulic pumps, control components, hydraulic cylinder seals and other poor or bubbles in the tank caused. Reinforced pad machine oil mixed with water, which because of the high humidity air by the air filter into the tank or the cooling water leakage caused. Hydraulic oil varieties or brands of replacement also cause pollution.
