KCB齿轮泵状态分析 KCB pump state analysis

KCB齿轮泵设有   阀作为超载保护，   阀的全回流压力为泵额定排除压力的1.5倍，也可在允许排出压力范围内根据实际需要另外调整。但注意本KCB齿轮泵的   阀不能作减压阀的长期工作，需要时可在管路上另行安装。 　KCB gear pump with relief valve as overload protection, safety valve of total reflux pressure for pump rated eliminate pressure 1.5 times, also can be in allow discharge pressure range according to actual need additional adjustment. But note that this KCB gear pump of the relief valve cannot be reducing valve long-term work, when need but in the line installed separately. 　

KCB齿轮泵主要有齿轮、轴、泵体、   阀、轴端密封所组成。KCB齿轮泵内有的泄油和回油槽，轮在工作中承受的扭矩力   小，因此KCB齿轮泵轴承负荷小，磨损小，泵。 KCB gear pump are mainly gear, shaft, pump body, valve, shaft end seal composed. KCB gear pump has to design the reasonable drainage and return chute, the wheels in the work under the minimum torque force, so KCB pump bearing load is small, little wear and tear, pump with high efficiency.

KCB齿轮泵主要用于各种机械设备中的润滑系统中输送润滑油，适用于输送粘度为5×10-6～1.5×10-3m2/s（5-1500cSt），温度在300℃以下的具有润滑性的油料。在输油系统中可用作传输、增压泵；在燃油系统中可用作输送、加压、喷射的燃油泵；KCB齿轮泵在   工业中，均可作润滑油泵用。KCB gear pump is mainly used for all kinds of mechanical equipment of the lubrication system conveying lubricating oil, it is suitable for conveying viscosity for 5 x 10-6 ~ 1.5 x 10-3 m2 / s (5-1500 CST), temperature at 300 ℃ with the lubricity of oil. In the oil system can be used for transmission, booster pump; In the fuel oil system can be used as a transport, pressure, jet fuel, KCB gear pump in all industrial fields, all can be lubricating oil pump use.

KCB齿轮泵流量：1.1m3/h-600m3/h压力：0.28MPa--2.5MPa，从主轴外伸端向泵看，为顺时针旋转。KCB齿轮泵主要用于油田、油库、港口、码头、船舶等大流量输油，卸油！ KCB pump flow: 1.1 m3 / h - 600 m3 / h pressure: 0.28 MPa -- -- 2.5 MPa, from the spindle overhanging end to pump look, for the clockwise rotation. KCB gear pump is mainly used in oil field, oil depot, ports, docks, shipbuilding and other large flow oil, oil discharge!

KCB齿轮泵经热处理有较高的硬度和强度，与轴一同安装在可   换的轴套内运转，泵内全部零件的润滑均在泵工作时利用输出介质而自动达到。另外因为KCB齿轮泵内有的泄油和回油槽，是齿轮在工作中承受的扭矩力   小，因此轴承负荷小，磨损小，泵。 KCB pump after heat treatment have higher hardness and strength, and shaft with installed in a replaceable sleeve inside operation, pump inside all parts of lubrication are in the pump work using output medium and automatic reach. In addition because KCB gear pump has to design the reasonable drainage and return chute, is gear in the work under the minimum torque force, so the bearing load is small, little wear and tear, pump with high efficiency.

1．表针指示逐渐增大：指针不摆动或指示不正常；. Hands indicating increase: pointer don't wobble or instruction is not normal,

2．表针摆动无规则；齿轮泵流量、压力不稳；内部声音不正常或电机局部发热2. Watch hand swing no rules, Pump flow, pressure unstable; Internal the voice is not normal or motor local heating

3．表针突然上升至红色区；表针摆动幅度增大，且有规则性波动(有时停机后再启动故障消失)；3. Watch hand suddenly rose to red area; Watch hand swinging amplitude increasing, and the regular sex fluctuation (sometimes stop before start-up failure disappear);

4．表针指示值大于0.75；运转不顺畅。流量压力低；4. Watch hand indicated value is greater than 0.75; Doesn't run smoothly. Flow pressure is low;

5．表针指示正常：或运行正常，表针大于0.75；5. Hands indicating normal: or operating normally, hands more than 0.75;
