一、圆弧齿轮泵的常见故障与维修方法 1)故障现象：泵不能排料 故障原因：a、旋转方向相反;b、吸入或排出阀关闭;c、入口无料或压力过低;d、粘度过高，泵无法咬料 对策：a、确认旋转方向;b、确认阀门是否关闭;c、检查阀门和压力表;d、检查液体粘度，以低速运转时按转速比例的流量是否出现，若有流量，则流入不足、 (2)故障现象：泵流量不足 故障原因：a、吸入或排出阀关闭;b、入口压力低;c、出口管线堵塞;d、填料箱泄漏;e、转速过低 对策：a、确认阀门是否关闭;b、检查阀门是否打开;c、确认排出量是否正常;d、紧固;大量泄露漏影响生产时，应停止运转，拆卸检查;e、检查泵轴实际转速; 二、圆弧齿轮泵的运行维护 (1)启动前检查全部管路法兰，接头的密封性。 (2)盘动联轴器，无摩擦及碰撞声音。 (3)首次启动应向泵内注入输送液体。 (4)启动前应全开吸入和排出管路中的阀门，严禁闭阀启动。 (5)验证电机转动方向后，启动电机。

1, arc gear pump of the common faults and maintenance methods 1) The failure phenomenon: pump does not discharge Cause of the malfunction: a, rotating in opposite directions; b, inhaled or discharge valve closed; c, entry no material or pressure too low; d, the viscosity is too high, pumps can not be expected to bite Responses: a, to confirm the direction of rotation; b, to confirm the valve is closed; c, check valves and pressure gauges; d, check the fluid viscosity, in order to lower speeds when the ratio according to speed the flow of whether there is, if traffic flows into the inadequate (2) failure phenomenon: pump flow less than Cause of the malfunction: a, inhalation or discharge valve closed; b, portal pressure is low; c, the export pipeline blockage; d, packing box leakage; e, speed is too low Responses: a, to confirm the valve is closed; b, check the valve is open; c, to confirm whether it is normal emissions; d, fastening; a large number of leak leakage affecting production, they should stop running, demolition inspection; e, check the shaft actual speed; 2, arc gear pump operation and maintenance (1) a pre-check all the pipe flange, joint sealing. (2) The dynamic coupling drive, no friction and collision sounds. (3) The first set should transport the liquid into the pump. (4) should be fully open before the start of the suction and discharge pipe valves, non-closing valve to start. (5) Verify motor rotation direction, start the motor.
