一、自吸油型液压泵的自吸油能力很强,无需外力供油。对于自吸油型叶片泵,液压油箱内的油液不得低于油标下限,要保持足够数量的液压油。液压油的清洁度越高,液压泵的使用寿命越长。70年代,随着静液传动技术、威格士液压控制技术和计算机技术的发展,压实技术和压实设备的研究有了长足的进展。
二、首先,静液传动应用到压实机械上,通过液压系统流量的控制,可以容易地改变马达的转速,实现压路机振动频率的连续调节,因而使得复杂的传动系大为简化。这一时期,振动压路机的研究主要集中在振动压路机参数优化方面,并逐步实现了振动频率与振动幅度的无级连续调节,改善了压实效果。
三、碾轮采用充气轮胎,一般装前轮3~5个,后轮4~6个。如改变充气压力可改变轮胎式压路机接地压力,压力调节范围为0.11~1.05兆帕。轮胎式压路机采用威格士液压、液力或机械传动系统,单轴或全轴驱动,宽基轮胎铰接式车架结构三点支承。压实过程有揉搓作用,使压实层颗粒不破坏而相嵌,均匀密实。机动性好,行速快(可达25公里/时),用于道路、飞机场等工程垫层的压实。
四、按轮轴布置有单轴单轮、双轴双轮、双轴三轮和三轴三轮等种。以内燃机为动力,采用机械传动或液压传动。一般前轮转向,机动性好,后轮驱动。为改善转向及碾压性能,宜采用铰接式转向结构和全轮驱动。前轮框架和机架铰接,以减少路面不平时的机身摆动。后轮和机架为刚性联接。
五、采用液压操纵、用威格士液压缸控制转向。前后碾轮均装有刮板以清除碾轮上粘结物。还装有喷水系统,用于压实沥青路面时,对碾轮洒水以防沥青混合料粘附。为增大作用力还可在碾轮内加装铁、砂、水等加大压重。
