Component composition and principle of booster engine:
1. Crankcase components
The crankcase is equipped with an oil sight glass, a respirator, a gear oil pump, and an oil filter screen at the bottom of the crankcase
2. Crankshaft, connecting rod and components
The crank of the crankshaft is equipped with a connecting rod. Both ends of the crankshaft are equipped with rolling bearings. The big end of the crankshaft is equipped with a pulley for rotation. The lubrication of the crankshaft is to install a gear cooling oil pump to the crankshaft and crosshead pin
3. Guide cylinder components
The guide cylinder is equipped with crosshead, crosshead pin and oil ring to separate the oil from the cylinder
4. Cylinder components
The cylinder is equipped with water inlet and outlet respectively. Water is added to circulate in the cylinder. Air inlet and exhaust valves are installed on both sides of the cylinder. Piston and piston rod are installed inside the cylinder. The piston rod is connected with crosshead screws. The bottom of the cylinder is equipped with a packing seal
5. Piston parts
Two sets of piston components, the piston is aluminum alloy, and the piston is equipped with oil-free piston ring and backup ring
6. Air inlet and exhaust valve
The intake and exhaust valves are steel parts and combination valves
7. Pipeline
The primary and secondary air inlets and outlets are welded with stainless steel pipes, and the primary and secondary pipes have safety valve pressure
Force sensor and temperature sensor
8. Cooler components
The cooler is divided into oil cooler and primary and secondary air coolers, which are divided into three groups. The water pump enters the cooler interface for cooling, and the outlet of the water pump is equipped with a water pressure sensor
Control system:
1. Control cabinet is installed on the main unit
2. There is an intelligent controller on the control cabinet panel
3. The booster inlet is equipped with an automatic loading and unloading valve
4. The booster's secondary air inlet is equipped with an oil-water separator for automatic drainage
5. The booster is equipped with an emptying valve. When the pressure reaches the rated pressure, it will be drained automatically to make the booster run with no load
6. The first and second stages are equipped with temperature sensors. If the temperature is too high, it will automatically alarm and shut down
7. The first and second stages are equipped with pressure sensors. If the pressure of the first and second stages exceeds the set pressure, it will automatically alarm and shut down
8. The water pressure sensor will automatically alarm and shut down when it is lower than the set pressure
9. The oil pressure sensor will automatically alarm and shut down when it is lower than the set pressure
