滑块平衡装置对大、中型压力机尤为重要,滑块部件重量对滑块平衡装置有较大影响,平衡装置越大,对整机布置影响越大。采用增压阀后,气压增高,平衡缸尺寸减少,储气筒直径减少,同时减少整机重量,减少加工和装配的难度。 Slider balancing device is particularly important for large and medium-sized presses. The weight of the slider component has a great influence on the slider balancer. The larger the balancing device is, the greater the impact on the whole machine arrangement. With the booster valve, the air pressure is increased, the size of the balance cylinder is reduced, the diameter of the cylinder is reduced, the weight of the whole machine is reduced, and the difficulty of processing and assembly is reduced.
