Excavators turned sluggish troubleshooting method (1) Check steering motor when the steering motor stator and rotor rotary valve Face Face or badly worn, will actually turn into the high-pressure fuel tank due to reduced steering action slow. If the steering cylinder, the central rotary joint performance intact, you can turn off the engine and killed after the steering wheel, at this time if the machine's front wheels can deflect immediately, and feel no weight, that explanation is steering a problem, should immediately repair or replacement. (2) one-way check valve when a steady flow of oil pressure in the hydraulic steering system steady flow due to one-way valve is weakened when the spring force and the low price of 6 tons excavators, will make steering cylinder inability to work, resulting in turn slow. In this regard, it can be one-way steady flow valve remote control port base nylon plugs removed, install the pressure gauge; then start the engine, the steering wheel to the left or right direction in situ killed and obstacles in the front side thing; this time, watching the pressure gauge readings, if pressure is less than 7Mpa, they should be one-way steady flow adjustment screw inside the valve properly (you must first loosen the lock nut) excavators price list, the fault can be excluded.泰安嘉 and Heavy Machinery Co., Ltd. a good hydraulic oil cooling system for large hydraulic excavators improved hydraulic oil cooling system (or rather should the hydraulic oil temperature control system), although the specific way the manufacturers use different, but the basic but the idea is the same, both the hydraulic oil temperature in continuous operation in the balance in the ideal range, but also make the hydraulic system in the cold state can be quickly put to work when heating (oil reaches normal operating temperature range). In the case of a qualified hydraulic oil under the premise of the hydraulic oil overheating when there excavator price, the hydraulic oil cooling temperature control system checks the following steps: ①, hydraulic oil cooler if there is dirt clogged, resulting in reduced efficiency of small and medium heat Excavators price, if necessary, clean the radiator. ②, fan speed detection system actually working pressure under extreme conditions, to determine the hydraulic circuit is faulty, if oil temperature sensor or control circuit is normal. In this case the fan speed and system pressure should be a maximum value; otherwise, the response system parameters can be adjusted accordingly or replace damaged components. Currently large hydraulic excavator working pump control, there are two main methods: limit load adjustment with pressure shut-off function (ie CUT-OFF function) (GLR) and load sensing regulator (LS) mode. The role of CUT-OFF function, when system pressure reaches the setting value, the swash plate angle variable pump is reduced, the pump can only be maintained at the pressure required to maintain the "residual" flow state to avoid overflow overflow valve overheating. To achieve this purpose, the system parameters to match the technical requirements so that the setting value is lower than the CUT-OFF valve set-value of the primary circuit pressure valve; otherwise, the primary pressure relief valve open will result in overheating. Also, check the secondary valve is working properly, this work must be carried out strictly in accordance with the technical requirements, respond to system parameters adjusted if necessary restorative. 6 tons excavator price | Kerry and Heavy | Luohe excavator price offered by 泰安嘉 and Heavy Machinery Co.,泰安嘉 and Heavy Machinery Co., Ltd.
