液压隔膜计量泵的价格与应用范围
液压隔膜计量泵，又称柱塞隔膜计量泵，是结合VAREM柱塞计量泵和ZILMET隔膜计量泵的特点而设计的一种计量泵。计量泵与被测介质的介质接触部分为隔膜，驱动部分为液压柱塞。因为膜片可以根据被测介质的不同而采用不同的材料，比如CSM、FPM、PTFE等，并且液压驱动可以满足高压测量的需要，柱塞隔膜计量泵的应用领域和工业压力都有了很大的提高。
以上是液压隔膜计量泵的定义，下面我来说说液压隔膜计量泵的价格与应用范围。
先来说说价格，液压隔膜计量泵的价格从3800元到数十万元不等，主要是与其流量与压力、还有材质有很大的关系，小流量、低压力、常规不锈钢304材质的液压隔膜计量泵的价格会便宜点，反之，则价格高一点。同时，电机配置变频电机、防爆电机、户外电机等，对价格也会有所影响。
下面我们再说下液压隔膜计量泵的应用范围：上海龙亚液压隔膜计量泵作为一种理想的化学品精确加药设备，它已广泛应用于石油化工、化工、油气田、电力、造纸、制药、环保、水处理等领域。从全球来看，经过近70年的实际应用和技术发展，市场需求进入稳定增长时期。在中国，随着经济的稳定和持续发展，未来几年市场规模将呈现持续快速增长的趋势。一些新的油气田项目已经开工。这个市场对计量泵的总体需求正在上升。1.3化工行业约占计量泵市场份额的10%，目前该市场的产品品牌处于ZD地位。用户对设备性能、可靠性和服务的综合要求逐渐提高。国际品牌和国产设备在各方面的综合优势越来越受到用户的追捧和青睐。1.4电力行业约占计量泵市场份额的10%，其中国际品牌占ZD地位。由于前一年五大电力集团新火电项目投资过快，每年新增机组超过3000×10kW，从2005年开始控制新火电项目审批。因此，从今年开始，新的热电厂项目数量将会减少，这将直接导致计量泵市场规模的下降。但一个新的亮点是，一些新核电项目的建设将带来新的增长点。1.5环保和水处理行业约占液压隔膜计量泵市场份额的45%，国际品牌和国内品牌市场份额平分秋色，是目前Z比例较大的计量泵市场。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，由于自然环境越来越恶劣，同一个家庭的努力也越来越多。特别是前几年某地区爆炸污染松花江后，国家加大了对环保的监管和投入。因此，环保和水处理市场将在未来几年迅速增长。1.6造纸、制药等其他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。
液压隔膜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。
镜面反射设计使活塞法兰和计量头可以自由安装在主动齿轮的左右两侧，现场安装灵活。
模块化设计，WaterSunny液压隔膜计量泵的现场安装维护非常方便。
该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。龙亚柱塞式隔膜计量泵的工作原理：在柱塞隔膜计量泵中，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。柱塞外套有可调滑环，用于封闭和调节空间。当调节孔关闭时，柱塞将液压油推入，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。
液压隔膜计量泵流量的调节可以通过柱塞法兰上的手动旋钮、变频器、伺服电机等来实现。上海钛龙液压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。空柱塞没有固定在电机的偏心轮上，柱塞在吸入行程中被弹簧弹回零位，有效防止吸入介质在计量头内形成堵塞时损坏泵。
The price and application range of hydraulic diaphragm metering pump
Hydraulic diaphragm metering pump, also known as plunger diaphragm metering pump, is a metering pump designed with the characteristics of valem plunger metering pump and zilmet diaphragm metering pump. The contact part of the metering pump and the medium of the measured medium is diaphragm, and the driving part is hydraulic plunger. Because the diaphragm can be used different materials according to the different medium under test, such as CSM, FPM, PTFE, etc., and the hydraulic drive can meet the needs of high pressure measurement, the application field and industrial pressure of the plunger diaphragm metering pump have been greatly improved.
The above is the definition of hydraulic diaphragm metering pump. I will talk about the price and application scope of the hydraulic diaphragm metering pump.
First, we will talk about the price. The price of the hydraulic diaphragm metering pump varies from 3800 yuan to hundreds of thousands of yuan, mainly due to its flow and pressure, and material. The price of the hydraulic diaphragm metering pump with small flow, low pressure and conventional stainless steel 304 material will be cheaper, otherwise, the price will be higher. At the same time, the motor is equipped with frequency conversion motor, explosion-proof motor, outdoor motor, etc., which will also affect the price.
Next, we will discuss the application scope of hydraulic diaphragm metering pump: Shanghai Longya hydraulic diaphragm metering pump, as an ideal chemical precise dosing equipment, has been widely used in petrochemical, chemical, oil and gas fields, power, paper making, pharmaceutical, environmental protection, water treatment and other fields. From the global perspective, after nearly 70 years of practical application and technology development, market demand has entered a period of stable growth. In China, with the steady and sustainable development of economy, the market scale will show a trend of sustained and rapid growth in the next few years. Some new oil and gas fields projects have been started. The overall demand for metering pumps in this market is rising. 1.3 the chemical industry accounts for about 10% of the market share of metering pump, and the product brand in this market is in the leading position. The comprehensive requirements of users for equipment performance, reliability and service are gradually improved. The comprehensive advantages of international brands and domestic equipment in various aspects are more and more popular with users. 1.4 the power industry accounts for about 10% of the market share of metering pumps, among which international brands are the leading. Due to the rapid investment of new thermal power projects of the five power groups in the previous year, more than 3000 × 10kW of new units are added each year, and the approval of new thermal power projects has been controlled since 2005. Therefore, from this year on, the number of new thermal power plant projects will be reduced, which will directly lead to the decline of the market size of metering pump. But a new highlight is that the construction of some new nuclear power projects will bring new growth points. 1.5 the environmental protection and water treatment industry accounts for about 45% of the market share of hydraulic diaphragm metering pump. The market share of international brands and domestic brands is equal, which is the market of metering pump with a large Z ratio at present. With the improvement of economic level, people's living standard is also improved correspondingly, and people have higher and higher requirements for the purity and safety of drinking water. At the same time, due to the increasingly harsh natural environment, the efforts of the same family are increasing. Especially after the explosion in a certain area polluted Songhua River in the previous years, the state has increased its supervision and investment in environmental protection. Therefore, the market for environmental protection and water treatment will grow rapidly in the next few years. 1.6 other industries such as paper making and pharmaceutical account for about 10% of the market share of metering pumps. It will also maintain a certain growth rate in the next few years.
The flow rate of metering pump does not change with the pressure, and can be adjusted linearly 0-100% under working and non working conditions.
The double head design of one pump makes the application of measuring different media at the same time become reality, which saves space and reduces cost.
The mirror reflection design makes the piston flange and measuring head freely installed on the left and right sides of the driving gear, and the installation is flexible on site.
Modular design, water sunny hydraulic diaphragm metering pump installation and maintenance on site is very convenient.
The product has built-in overpressure safety protection valve, which avoids the trouble of installing bypass of general metering pump, saves space and increases the safety of product use. Working principle of Longya plunger diaphragm metering pump: in the plunger diaphragm metering pump, the hollow plunger is driven by driving gear 2 and reciprocating, and the metering diaphragm is driven by hydraulic oil in the hollow plunger. Hollow plunger has special design adjustment space, so that the hydraulic oil inside and outside the plunger is the same. The plunger outer sleeve has adjustable slip ring, which is used for sealing and adjusting space. When the adjusting hole is closed, the plunger pushes the hydraulic oil into the metering diaphragm. In each stroke, the amount of hydraulic oil pushed by the plunger to drive the metering diaphragm is exactly the amount of the metering medium.
The flow of metering pump can be adjusted by manual knob, frequency converter and servo motor on the plunger flange. The flow rate of Shanghai titanon hydraulic diaphragm metering pump does not change with the pressure, and can be adjusted linearly 0-100% in static and working condition. High precision of adjustment. The empty plunger is not fixed on the eccentric wheel of the motor, and the plunger is spring bounced back to zero position during the suction stroke, which effectively prevents the suction medium from damaging the pump when the blockage occurs in the metering head.
