输送硅酮胶泵的安装调试步骤

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、较大的压力下输出最多的流量。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:

    输送硅酮胶泵可以输送高粘度、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, dont 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. Its 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 cant 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 cant flow theory. So if you need to flow with the actual working condition differ too much, it can only be better model bigger pump.

●高粘度泵概述High viscosity pump overview

　　NYP型内环式高粘度泵是一种容积式内转子泵。这种类型的泵自吸性能强，适用于输送不含固体颗粒和纤维的粘稠液体，甚至是半固体状态的液体，最高输送粘度达到3*105厘泊。具有体积小、重量轻、脉动小、噪音低、运转平稳、寿命长等优点。NYP high viscosity of the inner ring type pump is a kind of positive displacement rotor pump.This type of pump self-priming performance is strong, is suitable for conveying viscous liquid containing no solid particles and fibers, even half solid state of liquid, conveying viscosity up to 3 * 105 centipoise.With small volume, light weight, small ripple, low noise, smooth operation, long service life, etc.

　　该型泵可广泛用于石油、化工、颜料、化工、颜料、食品、肥皂、洗涤剂及制药等行业。This type of pump can be widely used in petroleum, chemical, pigment, chemical, pigment, food, soap, detergent and pharmaceutical industries.　

●高粘度泵使用时注意事项Matters needing attention when using high viscosity pump

　　进、出口管路的管径必须和泵保持一致；The diameters of inlet and outlet piping must be consistent with pump;

　　设计管路时应尽量减少弯头，且弯头角度不宜过小，进口管线不宜过长，以免影响自吸。

　　启动前每个注油杯都应家润滑油，且保证每天加油一次。

　　泵在工作前应该点动启动电机，观察转向是否和规定转向一致。

　　开机后观察运转是否正常，如有不正常噪音、特殊振动或温升过高等情况，应停机检查。

　　注意皮带松紧是否恰当，每半年调整一次。　

●高粘度泵工作原理：

　　高粘度泵是容积式内啮合齿轮泵，主动齿轮（外转子）带动被动齿轮（内转子）旋转时，不断产生封闭的空间，在吸油区齿轮逐渐脱离啮合而液体不断地充满齿间并被带到出油区，齿轮在出油区进入啮合时液体被排出。两个旋转齿轮的共同作用，形成一个稳定的体积排量，没有脉动。由于泵是完全对称的，泵可以反转，液流方向也随之改变。但应注意，泵的转向可能受到密封或泵内其它结构的限制，用户有反转要求时应在订货时做出说明。　　

●高粘度泵优点：

　　转子泵的轴向位置可调，不需要拆泵。

　　泵采用模块化设计，可根据不同的使用要求更换不同部件。可选夹层结构，以方便对泵加热或冷却，可以选择是否带安全阀，可以选择不同的密封形式，详见密封结构图。泵的各个零件可以选用不同的材质以适应具体使用要求。

　　不同的使用条件，泵的结构形式可能不同，具体应用请向厂家或本公司客户代表咨询。需要指出的是泵的转速愈高，泵的磨损愈严重，液体中如含有磨料物质，泵的材料应选用耐磨材质，在此种工况下，泵的压力和转速都应降低，高温条件下，则应增加泵的间隙，并采用耐热材料 。

　　流动稳定：流量与齿轮转速成正比，与压力无关

　　流动平稳：没有脉动和压力波峰，不会产生管道颤动。

　　多功能性：仅仅通过调整转子轴的位置，同一台泵既可以出来稀释溶液又可以出来沥青，糖浆，树脂，聚合物等高粘度液体。

　　可逆性：可以通过改变齿轮的旋转方向使液体反向流动，两种方向都能充分发挥泵的性能

　　自吸性：由泵产生高真空，允许在最大自吸高度实现快速自吸，取决于泵送液体的物理特性（温度，蒸汽压力，粘度等）。

　　建议性：只有两个活动部件：主动轮和动轮，只有一个轴封。

　　坚固的重载结构：低转速。特大球轴承的外部轴承座可以承受轴向和径向负载。

　　磨损率低：由于主动轮和从动齿轮不成倍数关系。这就意味着磨损可以被均匀的分散在每个齿轮上。因为一个齿轮上的每一个齿轮接触另一个齿轮上的每一个齿轮的次数一样。

磨损调节系统：转子边缘的磨损可以通过调整转子轴的位置来补偿。这样，即使在有相当大的磨损的情况下，也可以保证泵的稳定性。

　　维护简单，维护率低：不用移动泵，管道或泵驱动装置就可以进行检查和调节。

　　互动性：标准组件的设计可实现不同材料和特性零部件之间的替换。例如：有多种轴封系统可供选择，还可以安装带夹套的外壳和轴盖来代替标准部件。

　　端口位置可改变：泵壳可在轴承箱上旋转以从不同位置处吸排液体。

　　预热：加热夹套或是与外壳铸成一体，或是安装在端盖上，或是安装在填料压盖上。

　　旁路安全阀：旁路安全阀安装在泵上并且容易调节，在有些型号的泵上采取双重安全阀并带加热夹套。

●NYP高粘度泵的进出口

　　泵进出口的型式

　　常规泵进出口尺寸相同，进出口呈垂直布置，从驱动机向泵头方向看为右进上出。也可根据客户需要，加工成水平进出口型或左进上出型。连接方式有法兰型和螺纹型.

　　泵进出口负荷

　　泵在安装时，应限制泵的进出口所承受的管路负荷。螺纹联接的管接头不得承受负荷，否则会使泵的联接管产生松动或旋紧力矩（管螺纹联接处不允许有旋紧或松动的扭矩，以免）影响管路的联接效果。

●NYP高粘度泵的起动

　　泵在起动过程中应特别注意以下几个问题：

　　起动前要检查下列内容：

　　检查泵、齿轮箱和电机的对中程度；

　　检查过滤器中有没有焊皮和金属渣；

　　检查各连接部位连接是否紧固；

　　检查管路压在泵上的力和力矩是否超过给定的数值，如果温度较高，还应检查管路是否有膨胀节；

　　检查电气连接的正确性及电机的额定值，并检查电机转动方向是否正确；

　　检查泵的转动方向是否正确；

　　如有安全阀，安全阀安装必须正确，

　　检查泵轴是否转动灵活；

　　泵的内部不能是干的，特别是需要自吸的时候，应向泵内灌注一些油或输送的液体；

　　泵组装时在零件的表面有防护液，如果这种液体不能和泵送液体相容，则必须清洗；

　　最好在管路上安装压力表和真空表，方便观察泵的工作状态；

　　检查机械密封箱是否注满液体；

　　检查管路的阀门是否打开；

　　如果用内燃机驱动，请在起动发动机前保持离合器脱开；

　　泵起动后，检查液体是否进入到泵中，泵是否工作正常，如果长时间无液体进入泵中，应停机检查泵及管路。
