粗甘油输送泵用NYP110高粘度泵

 ●高粘度泵的安装调试步骤High viscosity pump installation and debugging steps

    高粘度泵是输送高粘度液体的齿轮泵，应做到在较低的功耗、较少的泄漏、较大的压力下输出Zui多的流量。在确定所要输送的介质时，应该严格遵循产品说明书上的规定，尽量使用厂家推荐的流体介质，并注意考虑系统的工作温度范围。当希望在某一较宽的温度范围内使用时，输送介质的粘度指数应该高些。输送介质不仅是能量传递的中介，而且也是润滑、密封及传热介质。液体粘度过高会增加内摩擦阻力，降低输出功率，浪费能量，并产生过高的系统温度.高粘度齿轮泵的出口管路上应当设置安全阀等保护装置，这样一旦泵的出口通道发生堵塞，就可以打开安全阀卸压。对于需要正反转的高粘度齿轮泵，其进出口管路上均需设置安全阀。High viscosity pump is conveying liquid with high viscosity gear pump, should be in lower power consumption, less leakage, under the pressure of large output the most traffic. When determining to conveying medium, we should strictly follow the provisions of the product manuals on use manufacturers recommend fluid as far as possible, and pay attention to consider the system operating temperature range. When you want to use in a wide temperature range, medium viscosity index should be higher. Medium is not only the energy transfer intermediary, but also lubrication, sealing and heat transfer medium. Liquid viscosity is too high will increase internal friction resistance, lower output power, waste of energy, and generate high temperature system. High viscosity gear pump outlet pipe shall set up relief valve or other protective device on the road, so once the clogging pump export channels, can open the relief valve pressure relief. For high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve.

　　●输送介质的优势:The advantage of the medium:

    高粘度泵可以输送高粘度、高浓度无固体颗粒或细小软颗粒的润滑性介质；效率高，性能稳定，使用寿命长。高粘度泵可以采用保温夹套结构，输送比较高的粘度物料时可以对高粘度泵进行保温，从而降低介质粘度，达到更好的输送效果，而单螺杆泵没有保温夹套结构；高粘度泵在使用一段时间后，如果泵内部间隙磨损后，不用拆泵可以自行根据高粘度泵所输送的物料粘度来调整泵的间隙，调整后和新泵一样可以达到良好的使用效果。高粘度泵可配安全阀，当泵或管路系统超压时，安全阀门打开，形成内部回流，保证系统安全。而单螺杆泵在泵本身不能设置安全阀，只能在管路中设置，提高了设备投入成本和安装成本。选择高粘度泵时必须考虑高粘度泵所输送的介质粘度，从而才能来确定高粘度泵的转速范围，根据高粘度泵的转速范围及所需工况条件下高粘度泵的正常流量范围，才能确定高粘度泵具体型号。需要注意的是一般介质可以这样来选择。High viscosity pump can transport high viscosity, high concentration without solid particles or small soft particles lubricity medium; High efficiency, stable performance and long service life. High viscosity pump can be used in a heat preservation jacket structure, transmission is higher when the viscosity of the material can be for thermal insulation in high viscosity pump, thereby reducing medium viscosity, achieve better transmission effect, and the single screw pump heat preservation jacket structure; High viscosity pump in use after a period of time, if the pump internal clearance after wear, don't have to dismantle the pump to according to the viscosity of material delivery by high viscosity pump to adjust the clearance between the pump and adjusted, and the use of the new pump can achieve good effect. High viscosity pump can match the relief valve, when the pump and piping system overpressure, safety valve is opened, the formation of internal reflux, ensure the safety of the system. And single screw pump in the pump itself cannot set the relief valve, can only be set up in line, increase the investment of equipment cost and installation cost. Choosing high viscosity pump must consider the conveying medium viscosity, high viscosity pump order to determine the scope of the high viscosity of the pump rotation speed, according to the working condition of high viscosity of the pump speed range and required high viscosity pump under the condition of normal flow range, to determine the high viscosity pump concrete models. It's important to note that it can be to choose a normal medium.

　　其中，有些特殊化学介质在一定温度下会改变其化学成分，所以需要在选择高粘度泵要特别注意泵的转速是否适合，因为泵的转速越高，正常工作中产生的热量就越大，一旦超过介质所限制的温度，那么就多所输送的介质造成了破坏。还有些食品类介质，比如果酱类，像我们日常中所食用的果酱、花生酱、豆瓣酱等，这些介质要求在输送过程中必须不能够破坏其内部的成分进行破坏，这就要求我们所选的泵的转速必须要低，才能保证高粘度泵在输送过程中不破坏所输送的介质。高粘度泵在运转过程中常常会出现卡死、抱轴转不动的现象，主要原因是高粘度泵往往都是输送的高粘度的介质，有些是有一些杂质的混合物理。如果泵的入口没有安装合适的过滤器，那么一旦大一些的硬质颗粒进入泵腔就会把高粘度泵的内外转子卡死，使泵转不动，严重的会把高粘度泵的内外转子毁掉。Among them, some special chemical medium under a certain temperature to change its chemical composition, so need to high viscosity pump in the choice whether to pay special attention to the speed of the pump is suitable for, because the higher the pump rotation speed, the greater the heat generated by the normal work, once more than media limited by temperature, then it is more than conveying medium caused damage. Also some food medium, such as the jam class, as in our daily consumption of jam, peanut butter, broad bean paste and so on, these medium requirements must be in the process of conveying can't destroy its internal composition, this requires that we selected the speed of the pump must be low, to ensure high viscosity pump does not destroy the transmission medium in the process of delivery. High viscosity pump in the operation process often appear stuck, holding shaft fixed phenomenon, the main reason is that high viscosity pump are often transport high viscosity medium, some are some impurities mixed in physics. If the entrance of the pump is not installed the appropriate filters, so once the larger hard particle enters the pump chamber would bring high viscosity pump rotor stuck inside and outside, make the pump turns motionless, serious will destroy high viscosity pump inside and outside of the rotor.

　　所以建议大家在安装高粘度泵的时候应该选择合适的过滤器来安装在泵的入口。高粘度泵抱轴的现象主要体现在不锈钢高粘度泵的较多，因为不锈钢材质含碳量低，所以热膨胀系数大，一旦泵的温度过高，就会造成泵的内部配件与配件之间的间隙缩小，到一定程度以后就会产生抱死现象。所以选择不锈钢材质的高粘度泵是一定要注明具体的使用温度，及介质的润滑性。介质粘度的高低与高粘度泵的转速有着密不可分的关系。如果高粘度泵输送的介质粘度过高，而所配的转速也过高的话，就会造成泵的流量很低、泵的噪音很大。如果电机功率还是按常规来配的话，那么电机也会造成过载。主要是泵的转速太高、介质粘度又太高这样就会造成泵阻力很大，电机的瞬间启动电流超过额定电流，造成电机过载；由于转速过高，使高粘度泵在运转时内部转子几乎只是形成了空转，围绕所输送介质打滑，造成吸不上料，或者是流量很小。在这种状况下，必须降低泵的转速，加大电机的功率，加大进出口的管径来减少介质的流动阻力。从而来完成介质的输送工作。转速降低以后，泵的流量会反而增加，而且泵的噪音会降低，但肯定打不到理论流量。所以如果与实际工况需要流量相差太多的话，那就只能更好型号更大一点的泵。So suggest you at the time of installation of high viscosity pump should choose the appropriate filter to installed in the entrance of the pump. The phenomenon of high viscosity pump holding shaft mainly reflects in the stainless steel of high viscosity pump is more, because of low carbon stainless steel material, so the thermal expansion coefficient is big, once the temperature of the pump is too high, can cause the interior of the pump parts and accessories the clearance between the narrow, to a certain degree after tends to lock phenomenon. So choose stainless steel high viscosity pump is must indicate the specific temperature, and medium lubricity. The discretion of the medium viscosity and high viscosity pump rotating speed of the intimate relationship. If the high viscosity pump medium viscosity is too high, and with the rotation speed is too high, will cause the pump flow rate is very low, the noise of the pump is very large. If motor power or conventional match, then the motor can cause overload. Mainly is the pump speed is too high, medium and high viscosity resistance is very big, this will cause pump motor moment of starting current more than rated current, motor overload; Due to high speed, high viscosity pump inside the rotor is barely formed when running idle, surrounding medium by sliding, cause not feeding, or flow rate is small. Under this situation, we must reduce the speed of pump, increase the power of the motor, increase the import and export of pipe diameter to reduce the flow resistance of the medium. Thus to complete medium transport work. Speed is reduced, the pump flow rate will increase instead, and the noise of the pump will be lower, but certainly can't flow theory. So if you need to flow with the actual working condition differ too much, it can only be better model bigger pump.

　　高粘度泵容易出现的另一个问题就是从动齿轮的销轴容易磨损，特别是对于输送没有润滑性的介质时，销轴磨损特别快。对此我公司改进加工工艺在原有的基础之上通过特殊设计改进给销轴配套加了一套注油润滑系统。在高粘度泵正常运转的情况下通过内转子的旋转产生的离心力形成的负压，利用注油系统通过特殊通道给销轴注油，从而解决了高粘度泵销轴磨损快的这一泵行业中存在的难题。Another problem of the high viscosity pump is driven gear pin easy to wear and tear, especially for conveying without lubrication medium, pin shaft wear particularly fast. I improved processing technology on the basis of the original company through special design improvements to pin shaft supporting a grease lubrication system. Under the condition of the high viscosity of the normal operation of pump centrifugal force produced by the rotation of the rotor within the formation of the negative pressure, the use of injection system through the special channel to pin shaft oil, so as to solve the high viscosity pump pin shaft quick wear of the problems that exist in the pump industry.
