高粘度泵在开始运转前，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。齿轮泵若是第一次运行，或长期闲置后再使用，最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。高粘度齿轮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最好安装一个止回阀。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。高粘度齿轮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 pump high viscosity pump installation and commissioning at the beginning of operation before the gear pump housing to be delivered within a liquid filled, for safe start. If the ambient temperature is below freezing, the pump should pass into the pre-heat steam for preheating, and then can start the gear pump. High viscosity pump direction of rotation with the import and export the oil line. Gear pump if the first run, or long-term idle before use, preferably in the case of no-load or low load start and one hour. If the running-in phase of pre-detect abnormal temperature rise, leakage, vibration and noise, should be down to check. High viscosity gear pump bearing or flange should be used with a common drive motor installed base, base, flange or bearing required to have sufficient stiffness to reduce the gear pump is running vibration and noise. Motor and gear pump shall be connected with a flexible coupling, concentricity of less than 0.1 mm, tilt angle not greater than 1 degree. Install the coupling is not allowed to play with a hammer, so as not to damage the gear gear pump and other parts. If the use of pulleys, sprockets and other drive bays support should be set to prevent the gear bearing by the radial force. Fastening gear pump, motor ground screw, the screw force should be uniform, reliable connection. Rotate the coupling should feel the gear pump can easily rotate, no clamping or other abnormal phenomena, and then you can pipe. High viscosity gear oil pump pipe diameter should be large enough, and to avoid sharp bend or narrow channels, reducing elbow, to remove unnecessary valves, accessories, as much as possible to reduce the pump mounting height, shorten the length of oil pipelines, to reduce pressure loss. Fittings and other components to be well sealed to prevent air intrusion to control cavitation and cavitation occurred. Check valve and valve gear pump output tube in the best way to install a check valve. This pump and output in the repair pipeline, the system does not occur in the liquid back. Gear pump with a load of parking, may also prevent the pump in reverse to generate its output pipe partial vacuum. It should be noted, outlet check valve can not hold against or appear stuck. High viscosity gear pumps also export pipeline safety valve and other protective devices should be set so that once the pump outlet channel clogging, you can open the safety valve relief. Safety valve with the pump or pump cover cast one, you can separate assembly. For the needs of the high viscosity gear pump reversing its import and export pipeline are required to set the safety valve.
