(Continued a) 4) diverter valve failure, premature opening. Check valve spring is deformed or failure, if the spring force is insufficient, you can increase the gasket between the spring and the seat. (5) spool and sleeve deformation, can cause both stuck. We shall go into the oil mouth of a small amount of hydraulic oil before filling installed, turn the valve should be flexible and comfortable, excavators school, if catching phenomenon to be polished. Sometimes, when tightening the bolts at the bottom steering uneven force, there will be the phenomenon of the valve is stuck, Tai'an best schools excavator, the correct approach is 2-3 times evenly tighten the bolts. Overview Frequently excavator excavator structure includes the power plant, equipment, Rotary, steering mechanism, transmission, running gear and auxiliary facilities. From the exterior, the excavator working device, Tai'an excavators school Which is good, the upper turret, running gear consisting of three parts. According to its structure and purpose can be divided into: Crawler, tire type, walker, hydraulic, semi-hydraulic, full swing, non-full rotation, general-purpose, special type, articulated, telescopic boom and other types. Working device is a direct means to complete the mining task. It consists of the boom, arm and bucket three parts hinged together. Landing boom, arm and bucket rotation are used telescopic double-acting hydraulic cylinder reciprocating control. In order to meet the various needs of different construction jobs, excavators can be equipped with a variety of work equipment, such as digging, lifting, loading, smooth, clamps, dozer, hammer, and other work tools. Rotary and walking device is a hydraulic excavator body, the upper part of the turret with a power plant and transmission. The engine is the power source of the excavator, they use diesel to be at a convenient venue, it can also be switched to the electric motor. Transmission through the hydraulic power of the engine is transmitted to the hydraulic motor, hydraulic cylinders and other actuators, to promote the work means action to complete the various operations Tai'an schools excavator | Excavator School | Kerry and excavators school by the 泰安嘉 and Heavy Machinery Co., Ltd. provided.泰安嘉 and Heavy Machinery Co., Ltd. (www.tajhzg.com/) strong, credible, in Tai'an, Shandong mining machinery industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Kerry and heavy and you hand in hand into the brilliant, for a better future!
