If you want to choose a loader accessory, you must first understand the type of loader accessory. Loader accessories mainly include: drive: drive shaft, main differential and rim. Working hydraulic oil circuit, hydraulic oil tank, working pump, multi-way valve, lifting oil cylinder and reverse bucket oil cylinder. Driving oil circuit: transmission oil pan, driving pump, omnidirectional torque converter, omnidirectional shift valve, transmission clutch. Steering oil circuit: oil tank, steering pump, steady flow valve (or priority valve), steering gear, steering cylinder. and many more.
Because the working environment of the loader is different, the working device of the loader accessory is also different, so when choosing the loader accessory, it is necessary to classify according to the model of the loader. For example, the common single-bucket loader is based on different engine power and transmission mode. , Operation system structure and loading method are classified. It includes three types of brakes: internal brake, parking brake and emergency brake. There are three types of brakes: shoe type, caliper disc type and wet multi-plate type. The driving mechanism of the brake generally adopts a booster device, and its power source includes compressed air, air cap oil and hydraulic pressure.
??If the altitude is too high, a special high prototype diesel engine should be used. The transmission type of the loader is generally hydraulic-mechanical transmission, and the key part is the selection of the torque converter. In domestically produced loaders, most of them choose dual-turbo and single-pole two-phase hydraulic receivers according to the situation. Ordinary diesel engines cannot be used at altitudes above 3000 meters. As for the power of the loader, diesel engines for construction machinery are generally used.
