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.
