EX1600 high voltage constant current pump has five major advantages:
A reciprocating double plunger pump in parallel:
EX1600P infusion unit is microprocessor controlled double plunger reciprocating pump with parallel.
???????? As a high withstand voltage, small pulsation, stable and reliable, convenient operation etc.. Due to the dual alternating infusion pump head,
In the same fluid volume, the piston rod and the sealing ring are longer than conventional double long pump series.
Reciprocating plunger pump compared with double parallel, tandem pump has the advantages of reciprocating plunger pump than the parallel double
Tandem pump pulse, system noise, long service life, including the service life of machinery and seals
The service life, but the production cost is high, and the high technical requirements, SHIMADZU is also the instrument, it
You want a few million parallel pump liquid chromatography tandem pump prices than it.
The world's most famous manufacturer of liquid phase WATERS, it is the use of the double piston reciprocating pump
Pump.
Two. EX1600P infusion unit has a process monitoring function:
1) The pressure on the lower limit;
2) seal wear caused leakage etc.;
3) instrument can timely alarm and in accordance with the procedures set, automatically stop the pump.
The three line leakage detection and alarm:
???????????????? All EX1600P infusion unit are arranged in the liquid leakage sensor, with on-line leakage monitoring work
Can. Once the instrument internal leakage, timely alarm, remind maintenance. EX1600 high performance liquid chromatography
The liquid leakage sensor chromatographic system independent monitoring of each unit, any unit leakage occurs, the alarm unit
Prompt。 At the same time, the whole system on the development of leakage receiving mode, the leakage of liquid through the liquid leakage pipe
The way to collect the bottom leakage unit receiving block, is discharged through the leakage outlet.
Four. Automatic plunger rod retracts function, convenient to replace the sealing ring:
????????????? To replace the sealing ring to provide a convenient, automatic indentation can control the plunger rod to avoid the replacement of precious stones
The process of sealing ring, gem broken rod of the plunger pump head when removing.
Five. Intelligent function:
1) After the column automatic cleaning function;
2) leakage automatic alarm function;
3) time setting program of man-machine conversation function;
4) automatic switch machine function;
5) to remind the state detection, fault, online help;
6) network control to judge the potential and the fault, and provide online solutions.
The basic technical indexes of EX1600HP
