Description

用于容积泵的补偿装置
本发明的目的是一种用于容积泵的补偿装置。
本发明有利地用于补偿在活塞泵传送点处的流速和压力的脉动,特别是在存在磨蚀性和/或腐蚀性液体的情况下,例如在用于处理陶瓷粉浆(slips)的设备中。
在这样的设备中通常使用大功率活塞泵,该大功率活塞泵沿处理线供给陶瓷粉浆的。布置成与泵的传送管线连通的储罐用于补偿在泵的传送点处的流速和压力的脉动。这些储罐局部充装有泵送的液体,局部充装有压缩至预定压力的空气。为了减少在泵传送点处的压力和流速的脉动,罐内的压力必须基本保持恒定。
补偿储罐基本根据储罐内部的空气压力来管理。为此,压力计布置成与储罐连通,并与控制面板连接,该控制面板确定压缩空气供给阀的打开和关闭。当压力降至低于给定界限值时,控制面板命令打开阀,以便再次使得空气注入储罐中。
压力计的使用会涉及多个缺点。实际上,压力计的操作可能受到杂质的存在和温度的突然波动的影响,从而危害到储罐内的压力的正确控制。
本发明的目的是提供一种用于容积泵的补偿装置,它能够改进当前可用的装置的特征。
通过下面对本发明实施例的详细说明,将更清楚本发明的特征和优点,该实施例通过附图1中的非限定实例来说明,该附图1是根据本发明的装置的示意图。
参考附图,根据本发明的补偿装置包括储罐(2),该储罐(2)预先布置成与泵(P)的传送管线(O)连接和与增压气体源(A)连接。泵(P)例如是活塞泵。压缩气体源(A)例如是通常存在于所有工业设备系统中的压缩空气回路。储罐(2)装备有用于安全和控制功能的压力计(7)。
控制阀(3)置于储罐(2)和气体源(A)之间。该控制阀(3)布置成打开或关闭在储罐(2)和气体源(A)之间的连接,从而分别采取打开构型和关闭构型。控制阀(3)与控制模块(4)连接,该控制模块(4)在打开和关闭构型中驱动控制阀(3)。
补偿装置包括与储罐(2)相关的液面传感器(5)。该液面传感器(5)用于检测在储罐(2)内部的液体的阈值液面高度。液面传感器(5)还与控制模块(4)连接,用于向模块(4)发送表示液体的液面高度高于阈值高度的至少一个操作信号。
换句话说,液面传感器(5)位于储罐(2)上的给定高度处,以便检测液体在该给定高度处的存在或不存在,其对应于阈值液面高度。当传感器(5)检测到液体的存在时,这意味着储罐(2)内部的液体的液面高度等于或高于阈值液面高度,且传感器(5)发送它的操作信号。当传感器(5)未检测到液体的存在时,储罐(2)内部的液体的液面高度低于阈值液面高度,且传感器(5)停止发送它的操作信号,并发送与操作信号不同的信号。
传感器(5)构造成直接测量储罐(2)内部的液体的液面高度。换句话说,传感器(5)的至少一部分或一个区域与储罐(2)内部的液体接触或能够接触。这使得能够获得基本瞬时和直接的、储罐(2)内部的液体的液面高度的测量值。
优选是,传感器(5)为电容类型传感器,但它也可以是其它类型,例如浮子传感器。
控制模块(4)设置成在有由传感器(5)发送的操作信号的情况下确定控制阀(3)的打开,并且在没有所述操作信号的情况下确定控制阀(3)的关闭。
控制阀(3)的打开使得增压气体能够被引入储罐(2)内部。由气体在存在于储罐(2)中的液体上施加的推力使得液面高度降低。当液面高度降低至低于阈值液面高度时,传感器(5)停止发送它的操作信号或者发送与操作信号不同的信号,且控制模块确定控制阀(3)的关闭。这样,通过确定控制阀(3)的打开和关闭(与由液面传感器(5)发送的信号相关),能够使得在储罐内的液面高度保持基本恒定,因此可用于空气的容积也保持基本恒定。
本质上,所述装置根据存在于储罐(2)内部的空气容积来控制,而不是根据在储罐(2)内存在的压力(如在当前可用的装置中)。这能够避免使用压力计来控制该装置。
在储罐(2)内的液面高度以预定时间间隔来检测。优选是,确定检测频率以便防止液面高度的过度升高,同时防止控制阀(3)的过于频繁的驱动。
