活塞式压缩机工作原理
Working principle of piston compressor
压缩过程：活塞从下止点向上运动，吸、排汽阀处于关闭状态，气体在密闭的气缸中被压缩，由于气缸容积逐渐缩小，则压力、温度逐渐升高直至气缸内气体压力与排气压力相等。
Compression process: the piston moves upward from the bottom dead center, the steam suction and exhaust valves are closed, and the gas is compressed in the closed cylinder. As the cylinder volume gradually shrinks, the pressure and temperature gradually increase until the gas pressure in the cylinder is equal to the exhaust pressure.
排气过程：活塞继钢纤维 驱鸟设备 保定通风管道 塑料土工格栅 检查井模具 流水槽模具 锻造厂家 华尔街铜牛续向上移动，致使气缸内的气体压力大于排气压力，则排气阀开启，气缸内的气体在活塞的推动下等压排出气缸进入排气管道，直至活塞运动到上止点。此时由于排气阀弹簧力和阀片本身重力的作用，排气阀关闭排气结束。
Exhaust process: if the piston continues to move upward, causing the gas pressure in the cylinder to be greater than the exhaust pressure, the exhaust valve will open, and the gas in the cylinder will be discharged into the exhaust pipe under equal pressure under the push of the piston until the piston moves to TDC. At this time, due to the spring force of the exhaust valve and the gravity of the valve plate itself, the exhaust valve is closed and the exhaust ends.
