The structure and loading of lowbed semi-trailer usually adopt concave beam (or well) frame, that is, the front section of the frame is gooseneck (the traction pin of the front section of gooseneck is connected with the traction saddle on the tractor, and the rear end of gooseneck is connected with the semi-trailer frame), the middle section is cargo platform (the lowest part of the frame), and the rear end is wheel frame (including wheels). When loading the mechanical equipment on the low flat semi-trailer, the mechanical equipment is usually loaded from the rear end of the semi-trailer, that is, the mechanical equipment is moved from the rear wheel frame or the wheels are removed, and then the mechanical equipment is fixed on the semi-trailer. The walking structure of low bed semi-trailer is made of high-strength international steel, with light vehicle weight, and ensures its anti distortion, anti-seismic and anti bumping capacity to meet different road bearing capacity. 4 Axles Lowbed Trailer,Lowbed Ramp Trailers,4 Axles Lowbed Trailer,Lowbed Trailer Gooseneck Shandong Chengda Auto Sales Co., Ltd. , https://www.chengdasemitrailer.com
It is understood that the use of a traditional single-end water ring vacuum pump will result in greater propylene waste and environmental pollution. The technical staff of the workshop has designed a set of jet pump collecting acrylic devices consisting of jet pumps, water pumps, air-water separation tanks and other multi-stage equipment. The device is simple in structure, easy to operate, and has a wide range of vacuum. It is suitable for pumping gas with granular media. Water is recycled by a centrifugal pump, which solves the problem of easy oxygen leakage during the vacuum process, thus realizing the venting of propylene. The gas is pumped to the gas cabinet for safe recovery.
The first use of jet pump to collect propylene to achieve win-win results
Recently, the smelting of polypropylene workshops has changed the tradition of using water ring vacuum pumps to empty propylene for many years. For the first time, the use of jet pumps to collect propylene has been successful. Not only can 130 tons of propylene be recovered annually, it can create more than 100 million yuan in profits, and it can also avoid the impact of propylene gas venting on the atmosphere. Environmental quality has achieved a win-win result for both social and economic benefits.
