Description

一种无油空压机缸盖散热结构 技术领域
本实用新型属于空气压缩设备技术领域，涉及一种无油空压机，特别涉及一种无油空压机缸盖散热结构。
 背景技术
无油空压机是将原有活塞与气缸的间隙配合改进成在活塞外圈设置皮碗，通过皮碗与气缸壁接触密封，从而在往复运动时无需机油润滑，现有技术中，气缸缸盖是把无油空压机缸体内部的热量通过上端面垂直散热齿形成的风道直接散到外部，虽起到散热作用，但缸盖表面散热齿的接触面积有限温度不能快速的进行风冷散热，导致内部温度还是比较高，使压缩空气所用的皮碗还是在高温下工作，导致皮碗高温不耐磨，从而影响皮碗和机器的寿命。
 技术问题
本实用新型的目的是针对现有技术中存在的上述问题，提供了一种通过对缸体内部的空气流道进行改进同时配合与其相适应的缸盖使其散热效果更好的无油空压机。
 技术解决方案
本实用新型的目的可通过下列技术方案来实现：一种无油空压机缸盖散热结构，包括相互配合的缸体和缸盖，所述缸体的内部设置有电机转轴支架，所述的缸体内位于支架的外侧为风叶腔支架的内侧为电机腔，其特征在于，所述的缸体内位于风叶腔的上方两侧竖直开设有空气流道，所述的缸盖两侧为与空气流道相连通的通风孔一，所述缸盖的顶部设置有一体式结构的散热齿，所述散热齿的间隔处开设有通风孔二，所述的缸体内位于两空气流道之间为用于安装缸套的空腔型结构且缸盖的中心为与其相配合的阀盖结构。
本无油空压机缸盖散热结构的技术效果为：电机的转轴通过支架支撑，电机转轴的端部安装有风扇，当空压机运行时电机带动风扇旋转往内输送空气，空气经电机本体阻挡后一部分由于空间的限制会产生向上流通状态，此时经过空气流道分别从通风孔一和通风孔二流出，本缸体的内部安装有缸套，活塞带动皮碗在缸套内往复运行配合上端阀板实现压缩空气，通过本实用新型结构，向上流动的空气与缸套外壁完全结构，可以大幅度带走其产生的热量，使皮碗运行在合适的温度状态下，使用寿命更长。
在上述的无油空压机缸盖散热结构中，所述的通风孔一呈圆弧状使其在上方形成挡片。
在上述的无油空压机缸盖散热结构中，所述的缸体内两侧对称开设有限位槽并通过限位槽卡设有防护罩，所述的防护罩与缸体之间通过径向穿设螺丝固定。
在上述的无油空压机缸盖散热结构中，所述的支架呈雪花状并与缸体之间为一体式结构。
在上述的无油空压机缸盖散热结构中，所述缸盖的阀板结构内两侧连接有进气口和排气口，并通过进气口和排气口分别将两侧的通风孔一分割成两个部分。
 有益效果
与现有技术相比，本无油空压机缸盖散热结构通过在缸体内部形成竖直向上的空气流道，同时配合缸盖上的通风孔一和通风孔二可以有效的增加缸体内缸套的散热面积，使缸套内活塞皮碗的使用寿命得到有效的延长。
