　　该型泵可广泛用于石油、、颜料、、颜料、食品、肥皂、洗涤剂及制等行业。

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

　　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。

   ●皮带带动沥青泵在开始运转前，往齿轮泵的壳体内灌满待输送的液体，便于安全启动。若环境温度低于冰点，应预先向泵内通入热蒸汽，进行预热处理，然后才可启动齿轮泵。高粘度泵的旋转方向要与进、出油口相符。齿轮泵若是次运行，或长期闲置后再使用，好在空载或小负荷情况下先跑合一小时左右。如果在跑合阶段预先觉察出异常温升、泄漏、振动和噪声时，应停机检查。高粘度齿轮泵的支座或法兰与其驱动电机应采用共同的安装基础，基础、法兰或支座均需具有足够的刚度，以减小齿轮泵运转时产生的振动和噪声。电动机与齿轮泵须用弹性联轴器连接，同轴度小于0.1毫米，倾斜角不得大于1度。安装联轴器时不得用锤敲打，以免伤害齿轮泵的齿轮等零件。若用带轮、链轮等驱动时应设托架支承，以防主动齿轮轴承受径向力。紧固齿轮泵、电动机的地脚螺钉时，螺钉受力应均匀，连接可靠。用手转动联轴器时，应感觉到齿轮泵能够轻松地转动，没有卡紧等异常现象出现，然后才可以配管。High  viscosity pump before starting work, to gear pump casing filled with liquid,  facilitate safe launch.If the environment temperature is below freezing, should  advance to pump into the hot steam, preheating treatment, and then to start the  pump.The direction of rotation of the pump with high viscosity, oil outlet in  accord.Gear pump is the first run, or long-term idle before using, had better  under the condition of no load or small load to run one hour or so.If in the  running-in stage in advance detect abnormal temperature rise, leakage, vibration  and noise, should stop check.High viscosity gear pump bearing or flange should  adopt a common drive motor installationFoundation, foundation, flange or support  all needs to have enough rigidity, to reduce the vibration of gear pump is  running and noise.Motor and gear pump with elastic shaft coupling, coaxial  degree is less than 0.1 mm, Angle shall not be greater than 1 degree.When  installing coupling hammer shall not be used, in order to avoid damage of the  gear pump gearAnd other parts.If use the belt wheel, wheel, etc, shall set  bracket support, in case of driving gear bearing by the radial force.Ground  screw fastening gear pump, motor, screw force should be uniform, reliable  connection.Turn the coupling with the hand, should feel can easily turn the gear  pump, no abnormal phenomenon such as clamping, then can be piping.

    皮带带动沥青泵的吸油管道内径应足够大，并避免狭窄通道或急剧拐弯、减少弯头，去除不必要的阀门、附件，尽可能地降低泵的安装高度，缩短吸油管道的长度，以减少压力损失。管接头等元件的密封要良好，以防止空气侵入，从而控制气穴与气蚀的发生。止回阀与安全阀在齿轮泵的输出管路上好安装一个止回阀。这样在检修泵及输出管道时，系统中的液体不会发生倒流。齿轮泵带负荷停车时，亦可防止泵倒转而在其输出管道内产生局部真空。应当注意，出口止回阀不能装反或出现卡死现象。高粘度泵的出口管路上还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。安全阀可以与泵体或泵盖铸成一体，也可以单独装配。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 gear pump oil suction pipe diameter should be large enough, and to  avoid the narrow channel, or a sharp turn, reducing elbow, remove unnecessary  valves, fittings, as much as possible to reduce the installation height of pump,  shorten the length of the oil suction pipe, in order to reduce the pressure  loss.Components, such as pipe joint sealed well, in order to prevent the air  intrusion, thus control air-pocket and the occurrence of cavitation.Check valve  and relief valve on the output of the gear pump tube had better install a check  valve.In the overhaul pump and output pipe, the system of fluid backflow will  not occur.Gear pump to stop loading machine, can be in the output pipe to  prevent pump reverse, and create a partial vacuum.It should be noted that the  outlet check valve cannot be installed backwards or stuck.High viscosity of the  pump outlet pipe also shall set up relief valve or other protective device on  the road, so that once the clogging pump export channels, can open the relief  valve pressure relief.The relief valve can be cast and pump body and pump cover,  also can separate assembly.For high viscosity gear pump need positive  &negative, import and export all needs to set up the line safety valve.

  皮带带动沥青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.

   1、工作压力的选定1, select the work pressure

　　皮带带动沥青泵额定的压力是指泵连续工作时的高许用压力，而其工作压力则决定于外部负载，安装和调试的寿命与其工作压力直接相关。对于不频繁工作的齿轮泵，其工作压力可取为泵的额定压力，考虑到产品质量不同，好将额定压力降低20%～30%使用。对于经常工作于较高压力下的齿轮泵，其工作压力应比泵的额定压力低1～2个压力级。石油化工设备常常是24小时连续运转，这时泵的工作压力应该取得比额定压力低得多，且工作转速也应该低于额定转速。如果高粘度齿轮泵的工作压力调整过高，则会使齿轮泵在超负荷下运行。High  viscosity pump rated pressure refers to the maximum allowable pump continuous  work pressure, and its working pressure is determined by the external load,  installation and commissioning of life is directly related with work  pressure.For not frequent work gear pump, the working pressure is desirable for  the rated pressure of the pump, taking the quality into consideration, it is  best to used pressure rated lower 20% ~ 30%.For often work under high pressure  gear pump, the working pressure shall be lower than the rated pressure of the  pump 1 ~ 2 pressure level.Petrochemical equipment are often 24 hours of  continuous operation, and at this time of the pump working pressure should be  obtained was much lower than the rated pressure, and the work speed should be  lower than the rated speed.If the high viscosity gear pump high pressure  adjustment, will make the pump running under overload.
