Description

一种新型输送机组
技术领域
本实用新型涉及一种化工原料输送机组,尤其涉及一种新型高温高压油介质输送机组。
背景技术
现有技术中输送介质多采用高速泵或离心泵。然而高速泵对输送介质的粘度及纯净度有较高要求,其在输送介质的时候噪音和振动也较大,维修保养费用也较高;离心泵则易受汽蚀、气缚影响,且排出压力较小。往复式柱塞泵作为容积式泵的一种,柱塞经曲柄连杆机构在驱动力下把旋转运动转化为往复运动,将能量传递给流体,以完成流体输送。对于高温高压油介质的输送,因需要较高的泵送压力范围,对所输送的介质也要有较强的适应性,适合采用往复式柱塞泵进行输送。因此亟待一种采用往复式柱塞泵的输送机组,可以高负荷、长周期可靠运行,稳定泵送高温高压油介质。
发明内容
本实用新型针对现有技术中存在的不足,提供一种布局合理、便于操作、检查和维护,能在-25℃至+45℃的作业环境下完成高负荷、长周期稳定输送高温高压油介质的新型输送机组。
本实用新型解决上述技术问题的技术方案如下:一种新型输送机组,包括安装在底橇上驱动机构、多缸柱塞泵、吸入管汇及排出管汇,其特征在于,所述驱动机构的输出端与所述多缸柱塞泵的机械输入端连接,所述吸入管汇和排出管汇分别与所述多缸柱塞泵流体吸入口和流体排出口连接。
进一步,所述多缸柱塞泵为3~5缸。
进一步,所述多缸柱塞泵的动力端还设有润滑油水冷系统。所述润滑油水冷系统由辅助电机驱动,通过外接水循环方式对多缸柱塞泵动力端的润滑油进行冷却。
进一步,所述驱动机构包括防爆电机、联组窄V型带和皮带轮,所述防爆电极通过联组窄V型带带动皮带轮运转。
进一步,在所述防爆电机的底部设有自动张紧机构。
进一步,所述自动张紧机构包括设于防爆电机底部的安装底板、活结螺栓和弹簧,所述安装底板靠近多缸柱塞泵的一侧与底橇铰链连接,另一侧设有通孔,所述活结螺栓一端穿过所述通孔与底橇铰链连接,所述弹簧设置在活结螺栓与通孔之间。
本实用新型的有益效果:多缸柱塞泵在驱动机构的带动下,可高负荷、长周期用于稳定输送高温高压油介质,为防止和避免设备长期运行过程中由于油温的升高,不利于各个部件的润滑,增加了润滑油水冷系统,从而达到调节油温,保证润滑油的润滑质量的目的,本实用新型还通过自动张紧机构和防爆电机自身重力实现调整联组窄V型带的张紧力,以延长联组窄V型带使用寿命。本实用新型布局合理,便于操作、检查和维护,能适应温度范围在-25℃~+45℃的作业环境。
在上述技术方案的基础上,本实用新型还可以做如下改进。
进一步,所述多缸柱塞泵采用填料盒和机械盘根润滑器实现润滑和密封。所述填料盒为两级填料密封,所述机械盘根润滑器采用原料油作为润滑油,保证了不会污染输送的原料介质。
进一步,所述吸入管汇和排出管汇分别设有吸入缓冲器和排出缓冲器。
进一步,所述排出管汇设有安全阀,当系统超压,安全阀开启并泄压,有效保护管汇和多缸柱塞泵。
进一步,所述吸入缓冲器采用囊式蓄能器,所述排出缓冲器采用球型机械式蓄能器。采用球型机械式蓄能器不仅有效减小流体脉冲,还可以免维护;采用囊式蓄能器,垂直安装,保证吸入介质平稳。
