隔膜计量泵的故障解决方法及安装密封件时的注意事项
隔膜计量泵作为一种理想的化学加药设备,已经广泛应用于石化、化工、油气田、电力、造纸、制药、环保、水处理等领域。在QQ范围内,经过近70年的实际应用和技术发展,市场需求进入了稳定增长时期。在ZG,随着经济的稳定和可持续发展,未来几年市场规模将呈现持续快速增长的趋势。随着经济水平的提高,人们的生活水平也相应提高,人们对饮用水的纯度和安全性要求越来越高。同时因为自然环境越来越差,同一个家庭的付出也越来越多。特别是近年来,GJ加大了对环境保护的监管和投入。因此,环保和水处理市场将在未来几年迅速增长。造纸、制药等行业约占计量泵市场份额的10%。未来几年也将保持一定的增长速度。
计量泵的流量不随压力变化,在工作和非工作条件下均可线性调节0-100%。
一泵双头设计,使一泵同时测量不同介质的应用成为现实,既节省空间,又降低成本。
镜面反射设计允许活塞法兰和计量头自由安装在驱动齿轮的左右两侧,现场安装灵活。
模块化设计,方便现场安装维护。
本产品内置超压安全保护阀,省去了一般计量泵安装旁路的麻烦,节省了空间,增加了产品使用的安全性。
计量泵流量的调节可通过柱塞法兰上的手动旋钮、变频器、伺服电机等实现。隔膜计量泵的流量不随压力的变化而变化,在静态和工作状态下可线性调节0-100%。调节精度高。空柱塞不固定在电机的偏心轮上,柱塞在吸入冲程中弹回零位,有效防止吸入介质在计量头内形成堵塞时损坏泵。
柱塞隔膜计量泵中,空心柱塞由驱动齿轮2驱动往复运动,计量隔膜由空心柱塞中的液压油驱动。空心柱塞有专门设计的调节空间,使柱塞内外的液压油相同。柱塞覆盖有一个可调节的滑环,用于关闭和调节空间。当调节孔关闭时,柱塞推入液压油以驱动计量隔膜。在每个冲程中,由柱塞推动以驱动计量隔膜的液压油的量正好等于计量介质的量。
在计量泵上安装密封件需要注意哪些事项?
使用龙亚系列隔膜计量泵时,请仔细阅读说明!
1.不要损坏密封表面或密封表面的密封线。平面密封的密封性能取决于上下端面;液压密封件的密封性能取决于与孔或轴相关的唇线。这些零件由石墨、橡胶、塑料、纤维等柔软有弹性的特殊材料制成,容易损坏。因此,在运输、安装和储存过程中,更需要给予特殊的保护和照顾。一旦损坏,往往会给密封部件留下很大的隐患;2.安装时注意平衡和对称。将密封件放在靠近有效密封面(或唇线)的位置。系统投入使用后,需要做好紧固密封的进一步观察和善后工作,防止系统工作过程中因工况变化(如增压)而出现微泄漏而导致的崩溃。3.不要强行安装VAREM计量泵,施工时不要野蛮粗暴。大动作的强制加载,必然会破坏密封件原有的预制结构,就像把预制混凝土打碎填充到需要的部位,必然会导致灾难。这类密封件的安装一定要非常小心谨慎,埋设一定要循序渐进;
Troubleshooting of diaphragm metering pump and matters needing attention when installing seals
As an ideal chemical dosing equipment, diaphragm metering pump has been widely used in petrochemical, chemical, oil and gas fields, electric power, papermaking, pharmaceutical, environmental protection, water treatment and other fields. Worldwide, after nearly 70 years of practical application and technology development, market demand has entered a period of stable growth. In China, with the stable and sustainable development of economy, the market scale will continue to grow rapidly in the next few years. With the improvement of economic level, people's living standards are also improved accordingly, people's requirements for the purity and safety of drinking water are higher and higher. At the same time, because the natural environment is getting worse and worse, the same family is paying more and more. Especially in recent years, the state has increased the supervision and investment in environmental protection. Therefore, the environmental protection and water treatment market will grow rapidly in the next few years. Papermaking, pharmaceutical and other industries account for about 10% of the metering pump market share. It will also maintain a certain growth rate in the next few years.
The flow rate of the metering pump does not change with the pressure, and can be adjusted linearly by 0-100% under working and non working conditions.
The design of one pump with two heads makes the application of one pump to measure different media at the same time a reality, which not only saves space, but also reduces the cost.
The mirror reflection design allows the piston flange and metering head to be freely installed on the left and right sides of the drive gear, which makes the installation flexible on site.
Modular design, convenient for field installation and maintenance.
This product has built-in overpressure safety protection valve, which saves the trouble of installing bypass of general metering pump, saves space, and increases the safety of the product.
The flow of metering pump can be adjusted by manual knob, frequency converter and servo motor on the plunger flange. The flow rate of the metering pump does not change with the change of pressure, and can be linearly adjusted by 0-100% under static and working conditions. High adjustment accuracy. The empty plunger is not fixed on the eccentric wheel of the motor, and the plunger springs back to the zero position during the suction stroke, which effectively prevents the pump from being damaged when the suction medium is blocked in the metering head.
In the plunger diaphragm metering pump, the hollow plunger is driven by the drive gear 2 to move back and forth, and the metering diaphragm is driven by the hydraulic oil in the hollow plunger. The hollow plunger has a specially designed adjusting space, so that the hydraulic oil inside and outside the plunger is the same. The plunger is covered with an adjustable slip ring for closing and adjusting the space. When the adjusting hole is closed, the plunger pushes hydraulic oil to drive the metering diaphragm. In each stroke, the amount of hydraulic oil pushed by the plunger to drive the metering diaphragm is exactly equal to the amount of metering medium.
What should be paid attention to when installing seals on metering pump?
Please read the instructions carefully when using Longya series metering pump!
1. Do not damage the sealing surface or the sealing line of the sealing surface. The sealing performance of the plane seal depends on the upper and lower face; the sealing performance of the hydraulic seal depends on the lip line related to the hole or shaft. These parts are made of graphite, rubber, plastic, fiber and other soft and elastic special materials, which are easy to damage. Therefore, special protection and care are needed during transportation, installation and storage. Once damaged, it will leave a great hidden danger to the sealing parts; 2. Pay attention to the balance and symmetry during the installation. Place the seal close to the effective sealing surface (or lip line). After the system is put into use, it is necessary to do a good job of further observation and aftercare of the fastening seal to prevent the collapse of the system caused by micro leakage due to the change of working conditions (such as pressurization). 3. Do not force the installation of varem metering pump, and do not be rude during construction. The forced loading of large action will inevitably destroy the original prefabricated structure of the seal, just like breaking and filling the prefabricated concrete to the required position, which will inevitably lead to disaster. The installation of such seals must be very careful, and the embedding must be gradual;
