Germany WILLE High Pressure Syring Pumps High pressure syringe pumps are digital microprocessor-controlled electromechanical piston pumps, which generate and regulate pressure and provide flow control in a variety range for different applications.This device is used for applications related to the control of pressure or flow rate for various fluids and gasses in laboratory tests.
As stated above, high pressure piston pumps are used to provide pulse-free flow rates over a wide range of pressures. The pumped fluid can be delivered at constant pressures and rates. Reliable, steady flow rates can be provided by high pressure pumps for long term tests and are appropriate devices that can replace the more traditional laboratory pressure pumps and volume change measuring devices.
High accuracy flow and pressure control with non-stop fluid pumping is a necessity for any flow fluid or pressure control application in relation to rock core analysis, reservoir engineering, oil and gas production enhancement studies and reactor feed/chemical synthesis in chemical processes.
Genral Description
The pressure piston inside the cylinder is moved by a stepping drive which enables the volume change measurement. There are variety range of pressures up to 4000 bar and volume ranges up to 1000ml which covers various applications.
It Includes a high accuracy pressure transducer to measure the pressure and by counting the steps of the incremental motor, the volume change would be measured.The device can be directly operated by a touch sensitive keypad or via PC with controlling software.
Single Type-High Pressure Syringe Pump
The device consists of a solid pressure cylinder with integrated spindle drive which pressurizes directly the fluid for the generation of pressures. An electronic pressure measuring facility is integrated and necessary for the operation.
This type of pump is mainly appropriate for:
• Constant flow
• Constant pressure
The pressure is regulated under closed-loop control. The pressure will be electronically monitored, when the pressure measuring unit is connected, and will shut down the drive at accident.
Twin Type High Pressure Syringe Pump
The Twin pumping system consists of two pressure cylinders and one controller. It provides two independent channels (output) and can be operated independently with different pressures and flow rates. Parameters for each pump are shown individually on the L CD display.
• The pressure pump can be programmed to operate for a specific period of time or deliver a quantified amount of fluid and then stop automatically
• The pressure pump can be programmed to complete a series of continuous steps or processes
Floor Type High Pressure Syringe Pump
This type of pump is mainly appropriate for the applications which requires Large volume of fluid for High pressure applications. It provides pulse-free flow rates over a wide range of high pressures. The pumped fluid can be delivered at constant pressures and rates.
Reliable, steady flow rates can be provided for long term tests and is an appropriate unit instead of using two pumps with continuous flow function.
Continious Flow Set Up
With a combination of valve packages, our dual pump (or two single pumps) can provide continuous (non-stop) fluid pumping for almost any kind of fluid for any desired time . To keep stability and accuracy when pumping fluid, the equalization of the pressure and flow in both pressure cylinders have been programmed by the controller.
For long-term tests (e.g. creep and sustained loading), it works automatically (software oriented) to feed in the beginning the cylinder of each pump, switching output line for each pump and refill of empty pump as quick as possible and pre-pressurized it and make it re ady to get into the working line.
For example, optional automatic three-way air or electric valves for tank feeding and outlet delivery can be provided as a dual pump series for unlimited continuous flow. The valve package can be comprised of a range of fluids in most applications.
There are different types of valve package that can be used acco rding to user requirements:
Air-powered Valve
• Works with almost all types of fluid
• Requires a pressurised air source of around 500 to 800Kpa.
• Works with viscous or corrosive solutions
• Constant volume without fluid movement during on/off operation
• High operating temperature (150 c)
Electric Valves
• Work with almost all types of fluid (corrosive or non-corrosive), viscous solutions
• Does not require any pressurised air source or power supply
• Works with liquefied gasses
• High operating temperature (150 c)
• Type of valve: one way
According to the application (fluid type, flow rate, volume), we are ready to design and select the appropriate valve type and configuration for your particular application. The valves can be controlled automatically or be hand operated and have different port sizes to fit your requirements.
SIEMENS Industrial Controller
The operation of the device requires the direct input of numerical values besides the use of the function keys. The control element made by Siemens Company is an advanced control panel which allows the user to enter the numerical values and control the system by other function keys easily. You need just to enter the values and press the run Key to start the operation.The operator panel gives the user access to all functions in the operation and service menu.This enables the user to start and run the pump as well as conduct calibration if needed. These controls are instinctive and simple to use.
All functions, such as actual status, flow rate and information on the pressure pumping ramp can be seen on the LCD display on the front of the device. Tests can be controlled manually by using the operator panel with the following features, as well as many more:
• Graphic display including 10 input membrane keys
• Setting force or position manually
• CE mark
• Ethernet interface
• 22 available different languages
• Multi language menu navigation
• Calibration function
• 4 free analogue Ports with A/D converter (interface +/-10 VDC)
• Display of actual pressure and volume
• Display of the piston position and direction Pressure control to a set value
• Ramping of pressure to a set value by de fining a pressure pumping ramp
• Ramping of volume to a set value by de fining a flow rate
• Definition of input parameters (e.g. calibration data, control parameters)
• Calibration of pressure and volume sensors
• Tarring of pressure
