The Engine, hydraulic pump, and distribution valve are the three major parts of excavators that people often say. Why is the excavator not powered by the engine like a car? It drives the vehicle forward through the gearbox and drive shaft, but the engine drives the hydraulic pump to rotate. Is the entire vehicle driven by high-pressure hydraulic oil through hydraulic motors, hydraulic cylinders and other hydraulic actuators? The engine provides power for the hydraulic pump, the hydraulic pump, hydraulic oil pipeline, hydraulic motor, hydraulic Cylinder, etc. are hydraulically driven, and the distribution valve is hydraulically controlled. 1. What is a plunger pump and what is a gear pump? Hydraulic pumps convert mechanical energy into liquid pressure energy. We generally see gear pumps and plunger pumps (for excavators and loaders). Common point: They all create pressure on the liquid through volume change. Difference: different institutions, different volume positions. The liquid volume of the gear pump is between the two gears, and the liquid volume is changed by the gear rotation. The volume of the plunger pump is in each plunger cylinder. Common large and medium-sized excavators generally combine plunger pumps and gear pumps to form a hydraulic pump assembly. Generally, the main pump is a plunger pump (higher output hydraulic oil pressure) for hydraulic travel motors, hydraulic swing motors, and hydraulic cylinders. Oil; the pilot pump is a gear pump (lower output hydraulic oil pressure) to supply oil to the distribution valve. Main pump assembly gear pump: The gear pump works by the closed movement of the two meshing gears when rotating. The gear pump is a gear drive to provide power, and the gear pump is a quantitative pump, which is mostly used for low-precision medium and low pressure control. Its main features are: simple structure, convenient manufacturing, low cost, low price, small size, light weight, good self-priming performance, insensitivity to oil pollution and reliable work. The main disadvantages are: large flow and pressure pulsation, large noise, and unadjustable displacement. It is widely used in various low-voltage systems. Gear pumps have the lowest requirements for oil. At the earliest, they were generally used in low-pressure systems (pilot pumps) because of their low pressure. Now gear pumps can achieve a pressure of about 25MPA. They are commonly used on machinery with low pressure requirements. The oil has large pulsation and cannot be variable. The advantage is good self-priming performance. Gear pump principle diagram Working principle External gear pump is a commonly used hydraulic pump in hydraulic systems of loaders and some small excavators.
