The piston compressor is a compressor that relies on the reciprocating movement of the piston to pressurize and transport the gas. Is a positive displacement compressor, also known as "reciprocating piston compressor" or "reciprocating compressor". It mainly consists of working cavity, transmission parts, fuselage and auxiliary parts. The working chamber is directly used to compress the gas, consisting of a cylinder, a cylinder sleeve, an air valve, a filler, a piston and a piston rod. Piston driven by the piston rod inside the cylinder for reciprocating motion and working chamber volume on either side of the piston size changes take turns to do the opposite, gas volume decrease side because of the increased pressure through the valve, volume increases on one side of the pressure, reduce the air through the valve inlet gas, driving part to realize reciprocating motion, a crankshaft connecting rod, eccentric slider, inclined plate, etc., Among them, the crankshaft connecting rod mechanism is the most common, which is composed of crosshead, connecting rod and crankshaft Piston Air Compressor,Piston Type Compressor,Piston Compressor,Oil Free Piston Compressor Yangzhou Mustang Air Compressor Co. , Ltd , https://www.aircompressor-ym.com
Recently, Shanghai Zhenhua Heavy Industry successfully completed the lifting and assembling of the world's largest gantry crane built for Singapore's Keppel Shipyard. The height of the gantry crane is 148 meters, which is equivalent to 45 stories. The lifting tonnage is 2,000 tons. It can successfully lift 1400 domestic vehicles at one time. It has successfully set a world record in the height of gantry cranes and lifting tonnage.
In the lifting assembly, the main beam lifting is the most difficult part of the whole process. The main weight of the gantry crane is about 4,000 tons, and the main beam should be raised to a height of 148 meters. The windward area is large and the risk is high. In order to ensure a smooth upgrade, the company's delivery team arranged real-time monitoring of the personnel at the 16 wind points and slipping trolleys at the scene, and set up an overall coordination of the upgrade command. Finally, after 14 days of hard work, the gantry crane successfully completed the main beam upgrade. .
The gantry crane will be put into use at the BrasFELS shipyard in Rio de Janeiro, Brazil in April this year, and will be used to lift the 1600-ton offshore platform module to meet the user's module lifting work on the top of the offshore platform.
