Background technique
In prior art, because storing a large amount of liquid in pipeline in major part industry water cooling system, thus cause liquid degeneration and cause because of long distance delivery liquid outlet pressure to reduce, particularly be provided with liquid tank in some industry water cooling system, and produce pressure by gravitational potential energy water is flowed out, be subject to highly impact and pipeline length causes the flowing fluid ratio that stores in cooling line more low with liquid outlet pressure.
Summary of the invention
The object of the invention is to overcome above defect, provide a kind of and can increase liquid outlet pressure, to reduce in cooling system fluid storage in pipeline without liquid tank pressurization system and controlling method thereof.
A kind of technological scheme without liquid tank pressurization system of the present invention is, it comprises liquid entering hole, liquid outlet, solenoid valve, one-way valve, pneumatic pump, control circuit, left pipeline in parallel and right pipeline is provided with as cooling pipe between liquid entering hole and liquid outlet, solenoid valve I and one-way valve I is provided with at the liquid entering hole end of left pipeline, solenoid valve II and one-way valve II is provided with at the liquid entering hole end of right pipeline, one-way valve III and one-way valve IV is respectively equipped with at the liquid outlet end of left pipeline and right pipeline, left pipeline is all connected with pneumatic pump with right pipeline, at pneumatic pump and be respectively equipped with solenoid valve III and solenoid valve IV between left pipeline and right pipeline, the working state of described control circuit Controlling solenoid valve and pneumatic pump, described solenoid valve is normally closed solenoid valve.
A kind of controlling method without liquid tank pressurization system of the present invention, it comprises the following steps:
Step 1: during system boot, control circuit detects left pipeline and whether right pipeline has liquid, as equal no liquid, then control circuit Controlling solenoid valve I is energized, solenoid valve II, solenoid valve III, solenoid valve IV and pneumatic pump no electric circuit, left pipeline is on state, and right pipeline closes; As left pipeline has the right pipeline no liquid of liquid, enter step 2, as right pipeline has the left pipeline no liquid of liquid, enter step 3; As left pipeline, right pipeline all have liquid, enter step 2 or step 3;
Step 2: control circuit Controlling solenoid valve II, solenoid valve III and pneumatic pump are energized, solenoid valve I and solenoid valve IV no electric circuit, and right pipeline is on state, and pneumatic pump extrudes the liquid in left pipeline from liquid outlet;
Step 3: control circuit Controlling solenoid valve I, solenoid valve IV and pneumatic pump are energized, and solenoid valve II, solenoid valve III no electric circuit, left pipeline is on state, and pneumatic pump extrudes the liquid in right pipeline from liquid outlet.
For the ease of Non-follow control pressurization system, by hand switch Controlling solenoid valve and pneumatic pump in described control circuit.
In order to the automatic operation of system, described control circuit is DSP circuit, and control circuit is according to the working state of detected pipeline state automatic control electric magnet valve and pneumatic pump.
The invention has the beneficial effects as follows, the present invention passes through two pipeline cross-circulation uses in parallel, run and start to remain in a pipeline there is no fluid storage with end, when system surprisingly occurs that two in parallel pipelines all have liquid, automatically the liquid in a pipeline can be discharged, the memory space of liquid in cooling line when greatly saving cooling system work and off working state, thus do not need to arrange liquid tank, pass through pneumatic pump, pneumatic compression devices and control circuit three overlap the operation of control strategy according to pipeline state Controlled cooling system, the pressure of liquid outlet is made to be the pressure that the pressure of conducting pipeline adds non-conduction pipeline internal air pressure pump, add the pressure of liquid outlet.
