液壓隔膜計量泵的價格與應(yīng)用范圍
液壓隔膜計量泵，又稱柱塞隔膜計量泵，是結(jié)合VAREM柱塞計量泵和ZILMET隔膜計量泵的特點而設(shè)計的一種計量泵。計量泵與被測介質(zhì)的介質(zhì)接觸部分為隔膜，驅(qū)動部分為液壓柱塞。因為膜片可以根據(jù)被測介質(zhì)的不同而采用不同的材料，比如CSM、FPM、PTFE等，并且液壓驅(qū)動可以滿足高壓測量的需要，柱塞隔膜計量泵的應(yīng)用領(lǐng)域和工業(yè)壓力都有了很大的提高。
以上是液壓隔膜計量泵的定義，下面我來說說液壓隔膜計量泵的價格與應(yīng)用范圍。
先來說說價格，液壓隔膜計量泵的價格從3800元到數(shù)十萬元不等，主要是與其流量與壓力、還有材質(zhì)有很大的關(guān)系，小流量、低壓力、常規(guī)不銹鋼304材質(zhì)的液壓隔膜計量泵的價格會便宜點，反之，則價格高一點。同時，電機配置變頻電機、防爆電機、戶外電機等，對價格也會有所影響。
下面我們再說下液壓隔膜計量泵的應(yīng)用范圍：上海龍亞液壓隔膜計量泵作為一種理想的化學(xué)品精確加藥設(shè)備，它已廣泛應(yīng)用于石油化工、化工、油氣田、電力、造紙、制藥、環(huán)保、水處理等領(lǐng)域。從全球來看，經(jīng)過近70年的實際應(yīng)用和技術(shù)發(fā)展，市場需求進入穩(wěn)定增長時期。在中國，隨著經(jīng)濟的穩(wěn)定和持續(xù)發(fā)展，未來幾年市場規(guī)模將呈現(xiàn)持續(xù)快速增長的趨勢。一些新的油氣田項目已經(jīng)開工。這個市場對計量泵的總體需求正在上升。1.3化工行業(yè)約占計量泵市場份額的10%，目前該市場的產(chǎn)品品牌處于ZD地位。用戶對設(shè)備性能、可靠性和服務(wù)的綜合要求逐漸提高。國際品牌和國產(chǎn)設(shè)備在各方面的綜合優(yōu)勢越來越受到用戶的追捧和青睞。1.4電力行業(yè)約占計量泵市場份額的10%，其中國際品牌占ZD地位。由于前一年五大電力集團新火電項目投資過快，每年新增機組超過3000×10kW，從2005年開始控制新火電項目審批。因此，從今年開始，新的熱電廠項目數(shù)量將會減少，這將直接導(dǎo)致計量泵市場規(guī)模的下降。但一個新的亮點是，一些新核電項目的建設(shè)將帶來新的增長點。1.5環(huán)保和水處理行業(yè)約占液壓隔膜計量泵市場份額的45%，國際品牌和國內(nèi)品牌市場份額平分秋色，是目前Z比例較大的計量泵市場。隨著經(jīng)濟水平的提高，人們的生活水平也相應(yīng)提高，人們對飲用水的純度和安全性要求越來越高。同時，由于自然環(huán)境越來越惡劣，同一個家庭的努力也越來越多。特別是前幾年某地區(qū)爆炸污染松花江后，國家加大了對環(huán)保的監(jiān)管和投入。因此，環(huán)保和水處理市場將在未來幾年迅速增長。1.6造紙、制藥等其他行業(yè)約占計量泵市場份額的10%。未來幾年也將保持一定的增長速度。
液壓隔膜計量泵的流量不隨壓力變化，在工作和非工作條件下均可線性調(diào)節(jié)0-100%。
一泵雙頭設(shè)計，使一泵同時測量不同介質(zhì)的應(yīng)用成為現(xiàn)實，既節(jié)省空間，又降低成本。
鏡面反射設(shè)計使活塞法蘭和計量頭可以自由安裝在主動齒輪的左右兩側(cè)，現(xiàn)場安裝靈活。
模塊化設(shè)計，WaterSunny液壓隔膜計量泵的現(xiàn)場安裝維護非常方便。
該產(chǎn)品內(nèi)置超壓安全保護閥，省去了一般計量泵安裝旁路的麻煩，節(jié)省了空間，增加了產(chǎn)品使用的安全性。龍亞柱塞式隔膜計量泵的工作原理：在柱塞隔膜計量泵中，空心柱塞由驅(qū)動齒輪2驅(qū)動往復(fù)運動，計量隔膜由空心柱塞中的液壓油驅(qū)動。空心柱塞有專門設(shè)計的調(diào)節(jié)空間，使柱塞內(nèi)外的液壓油相同。柱塞外套有可調(diào)滑環(huán)，用于封閉和調(diào)節(jié)空間。當(dāng)調(diào)節(jié)孔關(guān)閉時，柱塞將液壓油推入，驅(qū)動計量隔膜。在每個沖程中，由柱塞推動以驅(qū)動計量隔膜的液壓油的量正好等于計量介質(zhì)的量。
液壓隔膜計量泵流量的調(diào)節(jié)可以通過柱塞法蘭上的手動旋鈕、變頻器、伺服電機等來實現(xiàn)。上海鈦龍液壓隔膜計量泵的流量不隨壓力的變化而變化，在靜態(tài)和工作狀態(tài)下可線性調(diào)節(jié)0-100%。調(diào)節(jié)精度高。空柱塞沒有固定在電機的偏心輪上，柱塞在吸入行程中被彈簧彈回零位，有效防止吸入介質(zhì)在計量頭內(nèi)形成堵塞時損壞泵。
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.
