使用注意事项Application
1、工作介质 Operating Oil
可使用粘度范围在10-300mm²/s的石油基矿物油，推荐使用ISO VG46抗磨液压油 Viscosity range:10-300mm2/s,ISOVG46 Anti-wearhydraulic oil is recommended for better performance.
2、工作温度 Operating Temperature
工作温度范围 -10℃-100℃，为保证长期的可靠寿命，最佳工作温度范围20℃-80℃ Operating temperature range:-10℃-100℃. To ensure the reliable lifetime,the best operating temperature range is20℃-80℃
3、清洁度控制 cleanliness control
要求控制系统油液的清洁度水平，不超过9级（NAS 1638）或17/14（ISO 4066）Control cleanliness of system oil,can not over 9 lever(NAS 1638)or 1714(ISO 4066)
4、泵安装 Installation
轴与电机连接尽可能使用挠性联轴器，以避免产生弯曲力矩或轴向推力，轴与电机轴最大允许同轴度误差小于0.15mm Shaft and motor should be connected by flexible coupling to avoid harmnful effects.Concentricity of shafts between pump and motor is important to pump life snd should be within 0.15mm
5、吸入口压力与配管 Pressure of Inlet and Pipline
允许吸入口绝对压力为0.2-2 Bar。合理的配管通径应不小于泵的吸油品，以确保平均0.6-1.2m/s的最佳吸油速度 Absolute pressure of inlet is 0.2-2Bar.Diameter of absorb pipline caln't be smaller than inlet to ensure the best average oil speed 0.6-1.2m/s.
6、进出口连接 Inlet/outlet connection
尽力避免进出油管采用钢管硬连接，建议使用橡胶软管，避免出现额外的负载导致额外的噪音 Rubber hose is recommended to avoid extra load causing extra noise.Don't connect with steel pipe.
7、维护 Maintenance
为提高泵的使用寿命，应定期检查系统的异常振动、噪音、油液温度、油箱内是泵有气泡生成以及有无泄漏等问题，并及时维护 In order to mke the life of pump longer,customer should check the systemin time,such as if abnormal shocking,noise,oil temperature,bubble in tank, leakage...and maintenance in time.
