3GR螺杆泵介绍和启动前的准备.
3GR screw pump is introduced and the preparations before startup.
本系列3GR螺杆泵主要有齿轮、轴、泵体、泵盖、轴承套、轴端密封等组成。齿轮采用双圆弧正弦曲线齿形制造。它与渐开线齿轮相比zui突出的优点是齿轮啮合过程中齿廓面没有相对滑动,所以齿面无磨损,运转平稳,无因液现象,噪音低、寿命长、效率高。该泵摆脱了传统设计的束缚,使得齿轮泵在设计、生产和使用上进入了一个新的领域。
The series of 3GR screw pump main gear, shaft, pump body, pump cover, bearings, shaft seals and other components. Gear with double circular arc sine curve profile manufacturing.With the involute gear is the most prominent advantages of meshing gear tooth profile surface during the no relative sliding, so no tooth wear, smooth running, because no liquid,low noise, long service life, high efficiency. The pump to get rid of the shackles of the traditional design, the gear pump in the design, production and use entered a new field.
3GR螺杆泵设有3GR螺杆泵作为超载保护,3GR螺杆泵全回流压力为泵额定排出压力的1.5倍。也可在允许排出压力范围内根据实际需要另行调整。但注意本3GR螺杆泵不能作减压阀*工作,需要时可在管路上另行安装。
3GR screw pump with 3GR screw pump as overload protection, 3GR screw pump full back pressure 1.5 times the rated discharge pressure of pump. Also allow the discharge pressure in the range according to the actual need to be adjusted. But note that this 3GR screw pumpcan not be valves need long-term work, can be installed in the pipeline.
3GR螺杆泵轴端密封设计为两种形式,一种为机械密封,一种是填料密封,可根据具体使用情况和用户要求确定。
3GR screw pump shaft seal is designed to end in two forms, one for the mechanical seal, one is packing seal, can be determined according to the specific conditions and user requirements.
3GR螺杆泵启动前准备
Preparation of 3GR screw pump start before the
一、启动前检查全部管路法兰,接头的密封性。
Before starting, check all the pipe flange, joint sealing.
二、盘动联轴器,无摩擦及碰撞声音,旋转顺畅。
Two, the dynamic coupling drive, no friction and collision sound, smooth rotation.
三、启动前应全开吸入和排出管路中的阀门,严禁闭阀启动。
Three, should be fully open before the start of suction and discharge pipe valves, it is strictly prohibited to close the valve to start.
四、验证电机转动方向后,启动电机。
Four, verify the motor rotation direction, start the motor.
五、开机使用
Five, using the boot
3GR螺杆泵校验与维修
Check and repair of 3GR screw pump
校验是3GR螺杆泵试验的一部分,是制造厂出厂试验的主要项目。出厂前一般都用常温的3GR螺杆泵校验台进行空气介质的开启压力整定和密封性试验。3GR螺杆泵常温校验台只能做开启压力整定和密封性试验。
Check is a part of the 3GR screw pump test, is the main project manufacturing factory test.The factory is used 3GR screw pump tester at room temperature air opening pressure of the medium setting and sealing tests. 3GR screw pump room temperature calibrator can only doopen the pressure setting and sealing tests.
一、3GR螺杆泵在什么情况下需要校验
A, 3GR screw pump need to be calibrated under what circumstances
1.*存放或*次使用之前
1 the long-term storage or use for the first time
2.定期校验
2 regularly check
3.严重损坏和锈蚀的阀
3 serious damage and corrosion of the valve
4.阀门铭牌丢失的阀
4 valve nameplate missing valve
5.铅封损坏的阀门
5 seal damaged valve
二、回座压力的调整意义和方法
Adjust the significance and method two, the back seat pressure
国标定义的回座压力指3GR螺杆泵达到排放状态后,介质压力下跌至一定值,阀瓣重新与阀座接触,亦即开启高度变为零是,阀门进口处的静压力,回座压力太低太高都不好,太低将造成介质和能量的损失,太高则达不到排放量,造成阀门频跳,原则是在能达到排放量的情况下尽量的调高回座压力,降低介质和能量的损失。
Standard definition of the back seat pressure 3GR screw pump to meet the discharge state,the medium pressure dropped to a certain value, again with the valve seat disc, which is opening height becomes zero, the static pressure at the inlet valve, back seat pressure is too low, too much is not good, too low will cause the medium and the energy loss, not too up toemissions, resulting in valve frequency hopping, in principle is to achieve emissions as far as possible the high back seat pressure, reducing medium and the energy loss.
三、调整方法
Three, adjusting method
回座压力是通过调节圈来调整的,调节的原理是间隙原理,间隙越小,喷出时阻力越大,托住阀芯下降的力越大,越不易回座,反之,间隙越大,阀芯越容易回落,回座压力越高。 对于只有下调节圈的3GR螺杆泵,调节圈向上调,回座压力下降,调节圈向下调,回座压力升高;对于有上下调节圈的3GR螺杆泵,上下调节圈的距离减小,回座压力降低,上下调节圈的距离增大,回座压力升高。
Back seat pressure is adjusted through the adjusting ring, regulating principle is the gap theory, the smaller the gap, discharge resistance is greater, boosting the spool downward force is greater, more not easy to block, on the contrary, the greater the gap, spool more easily fall, back seat pressure is high. For the 3GR screw pump only adjusting ring, adjusting ring to increase, the back seat pressure decreases, the adjusting ring to cut, the back seat pressure increased; the 3GR screw on the adjusting ring, upper and lower adjusting ringdistance decreases, the back seat pressure reduced, upper and lower adjusting ringdistance increases, the back seat pressure increases.
四、校验方法及其优缺点
Four, calibration method and its advantages and disadvantages
3GR螺杆泵校验有现场校验(在线校验)和校验台校验两种手段,条件允许下应该尽量在现场校验,因为现场校验更切合实际运行工况,因而更可靠。 现场校验的优点:便于对焊接式3GR螺杆泵的校验,可测定回座压力,测量准确 . 缺点是校验时间长,系统要反复升压。
3GR screw pump check on-site check (online check) and two means of checking calibration table, conditions should as far as possible in the field check, because the on-site verification more practical operating conditions, and therefore more reliable. Field calibration of advantages: easy to check the welding type 3GR screw pump, can be used to determine theback seat pressure, accurate measurement. The disadvantage is a long time checking, the system repeatedly to boost
