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. Taian Jia and Heavy Machinery Co., Ltd. how fast replacement excavator seal? Excavator seal within the central rotary joint and replace the boom cylinder seal, such as the traditional method is time-consuming and laborious, and is limited by space and equipment can not be quickly replaced in the field and carry out repairs. In practice, we worked out a kind of seal of rapid methods can improve efficiency 15 to 20 times. 1, replacing the central rotary joint seals (1) First unscrew associated with retaining screws and then lift hydraulic small shelf holding the lower gear box car agricultural excavator, and it rotates a certain angle, so that after a small decline shelf car, dragged to the side of the lower gear box. (2) off the oil return pipe closure (in order to avoid a large number of hydraulic oil flowing out of the core is pulled along the central rotary joint core). Remove the oil with 4 fixing screws on the disc. (3) hooks on both sides of the chest hung on opposite sides of said two core tubing joints; then jack against the vertical shaft small agricultural excavator sales price, rose jack while the core can be pulled out, It can replace a seal on it. (4) holding the top set of core central rotary joint, then 1.5t jacks will push the core back into place, other parts installed in reverse order to disassembly of the complex. The whole process only single operation (also co-operation), without removing any one tubing. Hydraulic lift truck frame available horizontal jack little modification, or use an existing small frame car Heilongjiang agricultural excavator price, but is available off the oil catches fire fill plastic alternative, chest can be made orchard agricultural excavator price, which is mainly composed chassis and adjustable chains composed, accompanied Jack to complete. Entire job no other auxiliary equipment, the use of the tool is very simple, especially for a quick repair in the field.泰安嘉 and Heavy Machinery Co., Ltd.
