Detailed ways

Referring to Fig. 1, a gas/liquid-driven reciprocating piston compressor or liquid pump includes a compressor body or a liquid pump body, a suction and discharge control system and a power source in/out control system, and the power source is a pressure gas source or Hydraulic source.

The body of the compressor or the body of the liquid pump is a left-right symmetrical cylindrical structure, which includes a cylinder body 1, and a reciprocating piston composed of a power piston 2 and two working pistons 3 is placed in the cylinder body 1, and the reciprocating piston and the cylinder body 1 adopt dynamic seal. The power piston 2 and the working piston 3 are integrally designed or rigidly connected, and the working piston 3 is placed in a mirror image relative to the power piston 2, forming two power chambers 4 and two working chambers 5, forming two power chambers 4 and two working chambers 5 The power source can be filled into the two power chambers 4 alternately, and the reciprocating pistons are alternately driven to compress the fluid in the two working chambers 5 .

The fluid suction and discharge control system includes: a fluid suction and discharge through hole located on the wall of the cylinder body 1 of the working chamber 5, wherein a fluid suction check valve 6 is arranged on the suction through hole, and a fluid discharge through hole is provided on the discharge through hole. The one-way valve 7, the fluid suction one-way valve 6 and the fluid discharge one-way valve 7 are connected with the fluid suction pipe 9 and the fluid discharge pipe 8 respectively, and the fluid discharge pipe 8 is connected with the fluid storage tank 15 through the fluid discharge regulating valve 14, and the fluid suction The pipe 9 is connected to a fluid intake regulating valve 13 .

The power source inlet/outlet control system includes two power source inlet/outlet through holes located on the wall of the power chamber 4, the power source inlet/outlet through holes are respectively connected to the power source inlet/outlet pipes (11, 12), and the power source inlet The solenoid valve 10 is arranged on the outlet pipe (11, 12), and the two power chambers 4 are controlled by the solenoid valve 10 to alternately carry out the process of constantly charging and discharging the power source.

The working principle of the air/liquid driven reciprocating piston compressor or liquid pump of the present invention is to control the power chambers on both sides to alternately charge and discharge the power sources through the solenoid valve, and alternately drive the reciprocating pistons to reciprocate in the cylinder to realize The process of alternate suction, pressurization, discharge and pressure relief of fluid in the working chambers on both sides.

The working process of the gas/liquid-driven reciprocating piston compressor or liquid pump is divided into suction, pressurization, discharge, and pressure relief.

Said depressurization, inhalation process refers to that since the electromagnetic valve 10 is controlled, the power chamber 4 on one side communicates with the power source inlet pipe, and the power chamber on the other side communicates with the power source outlet pipe, and the power source flows into the power chamber 4 to drive The reciprocating piston moves to the other side; the power chamber on the other side is in the state of discharging the power source, and the working chamber 5 on the same side as the power chamber 4 is actually in the state after discharge. There is only a clearance volume in the chamber, and the volume of the working chamber 5 moves with the reciprocating piston increases, the fluid in the clearance volume is decompressed, and the pressure decreases.

When the pressure difference between the inside and outside of the fluid suction check valve 7 reaches the set value of the fluid suction check valve 7, the fluid suction check valve 7 opens, and the fluid enters the working chamber 5 through the fluid suction regulating valve 13 and the fluid suction check valve 7 to start Inhalation process, until the reciprocating piston unidirectionally moves to the end of cylinder body 1, the inhalation process ends. The power chamber 4 also reaches the maximum full power source state, while the power chamber on the other side is in the state of emptying the power source, and the working chamber on the other side of the working chamber 5 is in the state after being discharged. After the reciprocating piston reaches the end of the cylinder body 1, it moves in the opposite direction due to the inertia effect, the pressurization and discharge process of the working chamber 5 starts, and the state of the control valve 10 changes. The power chamber on the other side of the power chamber 4 communicates with the power source inlet pipe, and the power source flows into it to drive the reciprocating piston to move, while the power chamber 4 in the maximum full power source fluid state communicates with the power source outlet pipe, and the movement of the reciprocating piston will The power source is discharged, the volume of the working chamber 5 decreases with the movement of the reciprocating piston, and the fluid is pressurized. When the pressure difference between the two ends of the fluid discharge check valve 6 connected to the working chamber 5 reaches its set value, the fluid discharge check valve 6 is opened, and the discharge process begins. The fluid storage tank 15 is in standby, and the discharge process ends when the reciprocating piston moves to the end of the cylinder body 1, while the working chamber on the other side of the working chamber 5 carries out the fluid pressure relief and suction process simultaneously with the movement of the reciprocating piston. In fact, the solenoid valve 10 controls the power chambers on both sides to alternately charge and discharge the power source, alternately drives the reciprocating piston to reciprocate in the cylinder body 1, and alternately pressurizes the fluid in the working chambers on both sides to complete the compressor or compressor. Liquid pump working process.

When the power source and the pressurized fluid are the same medium, the structure can be simplified as shown in Figure 2, that is, a through hole is directly opened on the working piston to communicate with the power chamber 4, and the working chamber 5 is directly connected to the power chamber 5 through the one-way intake valve 6. The cavity 4 sucks fluid, which reduces the fluid sucking regulating valve 13 and the pipeline and its accessories, and the structure is more compact.
