Technology and equipment environmental protection and safety of the design elements by betty
Equipment in the design process through before the full identification of hazards in the environment and the impact of risk, and design for the remedy of these factors, 11 to develop control measures to fully protect the safety of technical equipment, and environmental protection. In this paper, the technical equipment of the environment and dangerous hazards to identify and measure the impact of the development, made a systematic exposition and analysis for the effect and application of technique and equipment, green and healthy outlook.
An overview of Present, the railway truck production in order to meet diverse and changing to frequent variety production features such as the requirements of Qiqihar Railway Vehicles (Group) Co., Ltd. (hereinafter referred to as Qi Car Group) need to design and manufacture of each year a large number of processes and equipment, only In recent years, Brazilian exports of goods production, for example, the number of various processing equipment reached a total of 272. With the production of the increasingly tense situation and busy, and environmental protection, occupational health and safety system on the production requirements more stringent, making all kinds of technical equipment to meet the premise of using the functionality of its safety and environmental protection standards of the increasing demand. Therefore, the combination of technology and equipment put into use may have harmful environmental impacts and risk factors, in the process and equipment design on safety and environmental protection requirements become increasingly prominent and important.
2, process equipment, environmental impact and risk hazards mainly
Currently Qi car companies, technology and equipment put into use may have harmful environmental impacts and risk factors are mainly the following aspects:
1. Environmental impact (1) noise pollution, such as with the cylinder, valves and other components of the pneumatic system, composed of technical equipment, such as not taking appropriate measures, pneumatic components in the implementation of the action more often given the noise.
(2) hydraulic system, such as with pollution caused by oil spills from the tanks, control valves and other components of the hydraulic system composed of technical equipment, If not take steps, hydraulic components, often produced in the implementation of the action of hydraulic oil leakage.
(3) welding fume emissions and other operations of some important equipment in line with welding, shot blasting and other operations, such as improper to take measures that will result in smoke and dust emissions disorder.
(4) chip for emissions of some important equipment in line with cutting and other operations, such as not taking appropriate measures, will result in no order of discharge and on-site chip accumulation.
2. Dangerous hazards (1) noise damage can lead to a strong scene of noise deafness.
(2) improper protection of moving parts with relatively high speed or drive the device, easy to twist into the on-site personnel involved in or causing bodily harm.
(3)? – Turn lock and turn part of the dump limit malfunctions? -, Resulting in crushing the scene of such damage or scratches.
(4) improve and upgrade parts gear Zhidongshiling been dropped or not stopping traction conditions may lead to on-site personnel were injured by or scratches and other damage.
(5) walkway and fence does not meet the requirements may result in injury to others, fall scene.
Third, the environmental impact and risk of hazards to the design points
Put into use for the technology and equipment may have harmful environmental impacts and risk factors, the main measures taken by the following categories:
1. Control the welding fume emissions
Welding fume emissions is an important railway truck manufacturers environmental factors, must also formulate the corresponding well-established environmental management program.
This end, the company every year around this regard, the development of environmental management programs, establish the scientific objectives, careful preparation of the implementation plan, implementation of effective monitoring tools, and conduct strict inspection and timely dynamic monitoring. Especially with today’s stainless steel and other materials in the extensive application of the railway goods vehicles, welding fumes environmental impact of emissions on a more prominent spot welding operation workers, although with hats, masks, glasses and other protective equipment, but still often have a strong incentive for operators to dust eyes and upper respiratory tract such as the occurrence of occupational hazards, and even that some welders are made out of the job requirements. Short-term phenomenon that, long-term consequences even more disastrous. For this reason, in recent years in truck parts and other equipment, welding robot working station position, all summary of the dust cover removed and replaced by foreign and domestic from Harbin, Tangshan and other places, the introduction of a new type of professional manufacturer of welding fume purification equipment. Work, welding smoke exhaust fans vacuum suction cleaner is internal, large particles floating dust was the beginning of the filter are filter flow plate and deposited into the micro-level cleaning device through the smoke and exhaust emissions are filtered and decomposed inside the device, and then discharge compliance gases, welding fumes can be collected? – ring cleaning and regular removal. Monitoring by environmental protection departments to achieve the emissions standards, on-site welders are also very pleased to achieve a clean and civilized production, the concept of “Make employees health and safety” of a people-centered philosophy of environmental protection.
Characteristics combined with production of the season, especially in enterprises located in the northern climate characteristics, but also give full consideration to energy conservation requirements. To this end, the common development of technical and professional manufacturers? – Proposals, to enable equipment to try to achieve “self? – Ring”, such as welding smoke purifier and so on, through its own internal? – Ring use, avoiding unnecessary energy to discharge outdoors.
2. Welding special fixture
For? – Turn lock and limit failures, easy to produce rotary part of the dump? -, Resulting in crushing or scratching the scene of such injury problems, mainly selected to function with self-locking worm gear drive, safety pins, etc. agencies or components. For a pneumatic system, process equipment, such as the transfer K6 bogie pedestal welding fixture, as the set of process equipment parts in the direction of movement of the three axes are used wind power, so special configuration of the pneumatic control system (as shown), the system uses the pressure of 0.4MPa. To enable the positioning and clamping side frame smooth slow motion, clamping force suitable for the installation of the KLJ-type throttle control cylinder speed so as to control the clamping action agency action speed, installed QP-type regulators control the folder the implementation of tight body parts clamping force. In order to secure the side frame of the clamp, which in any case they would not be dropped from the fixture, pneumatic controlled by KLA-type check valve, loss of electric circuit clamp mode control. This course of their work in the fixture, either stop air power, would firmly gripping the side frame on the fixture, robotic welding operations to ensure the absolute safety when the machine. When fully operational procedures
