1, the rational use of hydraulic oil ①, hydraulic oil viscosity to determine the principles of hydraulic oil viscosity is small wheeled excavator price, in consideration of the hydraulic circuit operating temperature and efficiency of the premise that (pumps and motors and other components used in) hydraulic oil viscosity It is in the optimum range (16-36x10-6mm2 / s); and the ambient temperature corresponding to the minimum viscosity of the cold start short ≤1000X10-6mm2 / s; and viscosity corresponding to the maximum permissible short-term leakage of oil temperature ≥ 90 ℃, 10X10-6mm2 / s. ②, viscosity index (VI) which reflects a more direct indicator of the oil viscosity with temperature change of nature (ie viscosity-temperature characteristics of the oil), high viscosity index oil, showing the kind of oil viscosity with temperature change and a smaller degree of change; the other hand, larger. Viscosity index known foreign manufacturers (such as Mobil, Shell, etc.) hydraulic oils are VI≥110, about viscosity index VI domestic advanced anti-wear hydraulic oil = 95. The foreign production of high viscosity index hydraulic oil (HV) and multigrade engine oil viscosity index are VI> 140. This is for the use of large-scale imports of hydraulic excavators and the use of domestic hydraulic oil (or use engine oil as hydraulic oil) users to pay special attention. Reduce the viscosity index oil will adapt to the ambient temperature range reduced, if not using a non-when should oil manufacturers for relevant information shall be for the use of oil to make the appropriate adjustments, should also change the value of the device related settings if necessary ( such as extreme temperature, etc.). ③, other comprehensive performance due to modern large-scale hydraulic excavator working hydraulic system pressure is high (≥32MPa), allows a maximum operating oil temperature of hydraulic oil is also high (about 90 ℃), so in order to ensure the normal drain intervals within hydraulic system to work properly, it requires lubrication system selected oil oxidation stability, anti-wear, rust and corrosion resistance, anti-emulsification, anti-foam, shear Cean qualitative and extreme pressure load and other aspects with good quality. Problem How to repair leaking excavator excavator leakage phenomenon usually occurs in the engine parts, hydraulic components, hydraulic lines and a front work. Engine parts oil, diesel oil leakage may occur. Engine oil leak, resulting in insufficient oil level, it will cause the engine lubrication system does not work well, leading to abnormal wear of internal engine parts, engine damage would cause significant losses excavator customers. Diesel engine leak can cause abnormal consumption of diesel, increasing the cost of the work excavator customers, also increased the equipment fire accident hazard. Hydraulic components, hydraulic lines and front attachment excavator small leak of hydraulic oil price, primarily in seals at the hydraulic components, hydraulic rigid pipe and hydraulic hoses place. Hydraulic rigid pipe occurred mainly in the line of engagement surface and O-rings, hydraulic hose failure modes are: pipe surface damage, pipe assembly hardening, surface blistering, kink, pull-out joints, joints leak and so on. Hydraulic oil leak, causing hydraulic oil tank, this could lead to the hydraulic system does not work, could easily lead to damage to the hydraulic components. In addition, the hydraulic oil leakage will increase the risk of fire equipment. Engine oil, hydraulic oil will leak oil excavator severely affected, in order to reduce the risks, we have what it takes to take preventive measures? We recommended that the driver needs to refer to the excavator operator's manual on a regular basis engine and hydraulic components, hydraulic lines and a front work to check if the machine operating time is very long, such as 24 hours a day working excavator price list, you will need to be checked more frequently. Risks need to be more focused on checking the site: high-temperature parts, rough wear parts, bent parts and the like. Before the test, we need to be cleaned checkpoint, remove hydraulic components, piping above the dirt and other impurities. Order excavator price checking, recommended by the pump chamber, control valve chamber, sequential engine, pilot line, a front work carried out, to prevent the omission checkpoint. Once the check lines or O-rings fail leak, the driver will need to contact the dealer service personnel as soon as possible to replace the set piece.泰安嘉 and Heavy Machinery Co., Ltd. domestic excavator price | Kerry and Heavy | Anhui excavator price offered by 泰安嘉 and Heavy Machinery Co., Ltd ..泰安嘉 and Heavy Machinery Co., Ltd.
