用途:2CY齿轮泵主要用于各种机械设备中的润滑系统中输送润滑油。Purpose: 2 cy gear pump is mainly used for all kinds of mechanical equipment of conveying lubricating oil lubrication system.
工作原理:本泵系容积式泵，主、被动齿轮与泵体、左右泵盖组成进油、出油二个封闭空间，当齿轮转动时，进油腔的容积，由于啮合齿不断脱开，而由小变大。形成真空，将液体吸入，有齿谷带往油腔，而出油腔容积，由于啮合齿的不断进入啮合而大变小，油液受压缩而被排出，从而达到输送油料的目的。Working principle: this pump is a positive displacement pump, the main around, passive gear and pump body, pump cover of the oil, the oil two closed space, when the gears, the oil cavity, the volume of meshing teeth off constantly, and changes from small to big.Form a vacuum, the liquid suction, toothed valley to the oil cavity, the volume of the oil cavity, due to the constant into the mesh of the meshing teeth and large to small, oil is displaced by compression, so as to achieve the aim of oil.
结构说明:本系列泵主要由：左、右泵盖、泵体、主、被动齿轮轴、轴套、油封等零件组成。Structure description: this series of pump is mainly composed of: left, right, pump cover, pump body, master, passive gear shaft, shaft sleeve, oil seal and other parts. 
工作注意事项:1、开机前应检查泵轴转动是否灵活，有无卡阻现象，进出口管道上的阀门是否开启，泵的旋转方向是否正确。2、长时间没有使用的泵开机前应向泵腔中注入一定量的润滑液，以减少泵在吸油过程中的干摩擦，并可提高泵自吸性能。3、开机后如有不正常的噪音或过热现象，应立即停车检查。4、检查泵轴端有无泄露现象，如：对填料密封应适当调紧压紧盖、其他密封则应拆机检查。5、若输送热油，在开车时应均匀预热，预热是利用被输送的介质不断通过泵体进行的。6、泵停机时，首先切断电源，然后关闭进出口管道上的阀门，避免造成泵倒转。Work matters needing attention: 1, should check whether the pump shaft rotation is flexible, before starting the presence of jam phenomenon, import and export pipeline valve is open, the direction of rotation of the pump is correct.2, long time no use the pump to the pump before starting the cavity inject a certain amount of lubricant to reduce the pump in the dry friction in the process of oil absorption, and can improve the performance of self-priming pump.3, after the boot if there is any abnormal noise or overheating phenomenon, should immediately stop check.4, check whether there is any leakage on the pump shaft end phenomenon, such as: the packing should be properly tighten clamp cover and other sealing should teardown check.5, if conveying hot oil, while driving should be uniform preheating, preheating is to use the media constantly through the pump body to be delivered.6, when the pump stop, cut off power supply first, then close the import and export pipeline valve, avoid to cause back pump.
使用与安装:1、机组应安装在水平水泥基础上，用地脚螺栓固定。2、右联轴器应同轴，安装完成后，转动联轴器确认运转顺畅无负压力现象后，方可进入运行。3、泵不适合输送不洁油液，故在进口管端应设滤油器。4、泵无安全阀，建议在排油管路中，设安全阀，以确保系统安全运行。5、泵的安装高度，不超过允许吸上高度。6、泵的转向规定：从泵端向电机看，旋转方向为逆时针。Use and installation: 1, the unit should be installed in a horizontal cement, on the basis of land use fixed bolt.2, should right coupling coaxial, after the installation is complete, turn the coupling confirmed after running smoothly without negative pressure phenomenon, may run into.3, the pump is not suitable for conveying impurity oil, therefore, at the inlet pipe should be set oil filter.4 no relief valve, pump, it is suggested that in the discharge of oil pipeline, a safety valve, and to ensure the safe operation of the system.5, pump installation height, no more than allow on the suction height.6, pump steering regulation: look from the pump to the motor, for counterclockwise rotation direction.
