Worked under high rotating speed and pressure, so being widely used in hydraulic system.
The measuring pump that paraformaldehyde additive uses is plunger pump.But due to reasons such as plunger pump structures, caused by it
Flow is periodically pulsing, and system pressure thus can be caused to produce the pulsation in cycle.This pressure fluctuation can produce in systems
Raw periodic pressure wave, the additive flow for supplying subsequent processing will be caused to fluctuate, also cause each element in system to be made in addition
Periodically vibrate, creep, noise, or even damage.
Utility model content
The shortcomings that the applicant is directed in above-mentioned existing production technology, there is provided one kind is used for paraformaldehyde additive current stabilization system
System, so as to eliminate plunger displacement pump flow pulsation, realize that flow velocity is even steady, impulsive force reduces.
Technical scheme is as follows used by the utility model：
One kind is used for paraformaldehyde additive steady flow system, including additive storage tank, the output end of the additive storage tank
Plunger pump is connected, the output end of the plunger pump connects constant-current stabilizer, the first pressure is separately installed with the top of the constant-current stabilizer
Power table, nitrogen and pressure transmitter；Valve assembly, the pressure are provided with by pipeline between the nitrogen and constant-current stabilizer
Transmitter connects with valve assembly；The bottom of the constant-current stabilizer connects paraformaldehyde drying process equipment group by check valve
Part.
Its further technical scheme is：
The structure of the constant-current stabilizer is：Including pressure vessel, the inside of the pressure vessel is provided with pressure sensor,
The signal output part connection control circuit of the pressure sensor, the control circuit control plunger pump work；The pressure storage
Pressure gauge connection, nitrogen charging mouth and pressure transmitter interface are provided with the top of tank, is provided with the middle part of the pressure vessel side wall defeated
Entrance, bottom are provided with delivery outlet.
Pressure transmitter interface is provided with second pressure gauge.
The beneficial effects of the utility model are as follows：
The utility model is compact-sized, reasonable, easy to operate, by the effect of constant-current stabilizer, using storing additive, and profit
The gas pressure caused by nitrogen compresses realizes supplement additive pressure feed, saves energy consumption, realizes that constant current supplies, ensures conveying
It is constant to the additive flow in paraformaldehyde drying process apparatus assembly, make its functional reliability good, operating efficiency is high.
Because the utility model is to reduce influence of the liquid fluctuating pressure change to flow by nitrogen pressure effect
Easy device, not only easy to use, steady flow result is good, and precision is high, and can eliminate the stream of plunger pump compared with prior art
Amount pulsation.
The utility model using nitrogen compression caused by gas pressure realize supplement additive supply pressure, and then eliminate because
Flow pulsation caused by plunger pump structure feature, so as to realize that flow velocity is even steady, reduce impulsive force.
