• Working principle and technical parameters

1,Working principle
1.1 The compressor belongs to reciprocating, piston (with middle body and cross head), single acting, combination of air cooling and water cooling, three-stage compression, all oil-free and lubricated oxygen canned compressor (hereinafter referred to as the compressor).
1.2 The compressor is composed of the main engine, the motor, the support and the electrical control elements. The main engine and the motor are placed on the support. It is equipped with a one-way valve, an inlet ball valve, an exhaust globe valve, a cooling water pump and a flow meter, and a solenoid valve is installed in the inlet pipe and the unloading pipeline.
1.3 When the compressor is working, the motor drives the crankshaft to produce rotary motion through the v-belt, and the piston produces reciprocating motion through the connecting rod, which changes the cylinder volume and leads to the change of gas pressure in the cylinder. The gas in the pressure state is inhaled into the cylinder through the inlet valve block, the inlet solenoid valve, the inlet pipe and the inlet valve. The compressed gas is compressed into the required pressure through three stages and discharged through the one-way valve, pipeline and exhaust valve block for use.
1.4 It is provided with inter cooler between the first, second and second and third stages.
2,This product is suitable for:The compression medium is dry non-granular oxygen pressurization or tank.
3,Basic technical parameters (see P6 -- table 1).
Control system
The control system of the compressor is composed of YKHMI touch screen, PLC controller, pressure sensor (inlet and supply pressure), temperature sensor (first stage temperature, final stage temperature), inlet solenoid valve, unloading solenoid valve, one-way valve and pipeline. The volume flow rate of the compressor should be able to adapt to the change of the volume of air used. When the volume of air used is less than the volume flow rate of the compressor, the volume flow rate should be adjusted by the control system to prevent the continuous rise of the supply pressure. Display pressure and temperature in real time while working.
When the inlet pressure reaches 0.4mpa, press "start up", and the compressor starts to work according to the starting control sequence of When the exhaust pressure reaches the set value of 15MPa, the motor power will be cut off automatically and the compressor will stop working. At this time, the intake electromagnetic valve is closed, the air inlet is closed, and the unloading solenoid valve is opened, so that the high-pressure cavity and pipeline of the exhaust end are connected with the air inlet and the air inlet, so as to reach the same pressure on both sides. At the same time, the cooling pump stops working, so as to realize no-load starting.
