2. After a reasonable use of the former timely maintenance installations bearing (W) should be first in the sports watch topcoat shaft and the bearing to provide grade clean oil, Anhui small digging machines, main bearing repair the initial startup: Excavator engine maintenance knowledge. You should close the fuel switch and throttle placed in the low position, start the engine is operated observed idling longer than 5min. Work out a new machine and after a run-in engine overhaul work in the run-in period prohibits prolonged surge in the load, slashed and high-speed operation under the state of work; working at full capacity for a long time after not immediately stop. You must load, low-speed operation after 15min stop, otherwise, the internal heat not scattered out. Strengthen the oil filter, crankshaft ventilation ventilation cleaning and maintenance work, according to the instructions require timely replacement of filters; to control the temperature of the engine is operating normally prevent radiator "boil", is strictly prohibited without cooling water on the road; Check and adjust in a timely manner the technical condition of the crankshaft and the bearing work. Oil strainer should be cleaned regularly, cleaning is to be careful to check whether there is oil leaking float head. If, 60 hours digging machine prices, can drill a small hole next to the float there, the oil release and seal welding. Otherwise, the float head leaking into the oil strainer will sink to the bottom of the oil pan, the deposition of stolen goods being sucked up and clog filters and oil passages. To 3. Periodic inspection, adjustment without disassembly inspection, namely by means of an instrument or empirically sound auscultation. After bearing damage, ultra-small digging machine prices, percussion will be issued bearing the engine running. Main bearing issued a heavy stifling "boring boring", the higher the engine speed, load greater voice louder; the throttle when suddenly sound more prominent, small second-hand excavator price, even the engine will generate vibration shaking; When the alloy layer off, bush-burning, or the gap increases to a certain extent, at any speed or load, generally can hear percussion; to determine which road the main bearing ring, generally based on the beep to determine the location, but also suspicious around two adjacent cylinders bearing off the fire, if the sound is lower then the sound of the track bearing. Connecting rod bearing noise than the main bearing light percussion, listening to the outside of the body like the issue of tapping with a hammer firebrick "Da Dada" sound sound short and solid. Excavators air conditioning is not cooling country? Ensure the normal operation of the excavator air conditioning cooling device each time before driving please check the following essentials. 1. If the compressor is dirty condenser cooling effect is reduced if there is dirty, wash with water and so on. Note: Do not use high-pressure water cleaning condenser. Condenser mounted in front of the radiator are particularly vulnerable to gather dirty, wash it with water. 2, V-belt tension check if the V-belt tension relaxation, the V-belt life because the belt sliding, rocking significantly diminished, hand pressure way to detect whether the V-belt slack. 3, pipe connection parts Please check attached to the case confirmed that oil penetration of the connecting portion of the cooling device, dirt and dust by visual way. 4, after a very long time without the use of reused · Refer to "check the cooling means" to conduct a comprehensive inspection of all. ? When starting the cooling device, please do not dramatically increase the speed of the compressor. Note that in order to extend the life of the cooling system and maintain good performance, inspection is recommended to start using when prevention preparedness check. 5, off-season (not often) when operating · Whether summer, winter and all please install the cooling device components, add refrigerant. Note: Regardless of summer and winter, are well install the compressor drive belt. 6, will not be used ? Make every 2 to 3 weeks to run 1 to 2 times the cooling device. Compressor seals to prevent gas leakage site effect. In addition, the oil can be prevented from leaking components help to maintain the performance and life of the compressor.泰安嘉 and Heavy Machinery Co., Ltd. 60 hours digging machine prices, Anhui small digging machines, Kerry and Heavy (View) by 泰安嘉 and Heavy Machinery Co., Ltd ..
