3. Control pollution caused by noise

In the process equipment equipped with a pneumatic system consisting of cylinders, gas valves and the like, a muffler or a throttle muffler is widely provided on the exhaust port of the valve or the reversing valve. For example, in the past few years, the C80, C76 and other models of the side wall group fixtures are equipped with 80 and 70 QGBZ (S2 type) and QGBZ (MP3 type) cylinders, matching the K34R8B type valve, through the application Mufflers such as FXS (sintered) and PXL (sintered) exhaust throttling greatly reduce or even eliminate noise pollution, while reducing and avoiding possible deafness to close-range operators.

4. Hydraulic system transformation

Use new high-quality sealing ring or hydraulic valve, joint and other components with good sealing function to prevent oil leakage and pollution. For example, before the transformation of the middle beam line of the truck factory, the system has serious oil leakage, and the site is 綷- often large area oil accumulation. In the case of serious, the on-site operators even have nowhere to work. To this end, in the process of the transformation of the Zhongliang line, the focus is on the transformation of its hydraulic system. Therefore, the design and construction of professional units such as Dalian Combined Machine Tool Research Institute were entrusted, and advanced hydraulic components such as Rexroth were adopted. After the transformation, the oil leakage phenomenon was completely eliminated, and the effect was very obvious.

5. Chip discharge

At present, with the large-scale application of large-scale CNC machine tools and machining centers, production efficiency is greatly improved. For this reason, in designing the important process equipment for the cutting operation, in order to solve the problem of chip discharge, the chip discharge device is widely used, and the chip conveyor is in the normally open state during production, and the chips are discharged after the chips are generated, and the collection is concentrated. Handle it properly.

6. Transmission equipment

For process equipment with mechanical transmission, such as screw drive, belt drive, chain drive and open gear transmission, set the necessary protective cover, sheath or baffle to prevent the body personnel from getting caught or twisted into the body. Dangerous parts.

7. Brake equipment

For the lifting and transmission brake failure, the lifted part is dropped or the tractor cannot be stopped, which may cause injury or scratching of the site personnel. The power source is equipped with a brake motor or ordinary motor output. The rear part of the shaft is equipped with a brake, such as a block brake.

8. Walking platform and guardrail

If the walking platform and guardrail do not meet the requirements, it may cause injury to the site personnel. The design is strictly in accordance with relevant national standards, such as the height of the guardrail is 1 050mm, and the cage is added when the ladder is over 3m high; The width, the height of the handrail column and the spacing dimensions are to comply with the standard regulations.

Fourth, the effect test analysis and prospects

In recent years, the production practice has proved that all the process equipment that fully recognizes the environmental impact and dangerous hazard factors before design, through the design of these factors to solve the problem, to develop control measures to fully guarantee safety and environmental protection, these process equipment After being put into production and use, it fully demonstrates the superiority in safety and environmental protection. The specific performance is as follows: Under the premise of satisfying the performance, there is no environmental impact and operational hazard, and the expected effect is achieved. This is further verified by daily process discipline inspection, safety production inspection, safety and quality standardization inspection and inspection, and environmental and occupational health and safety system annual inspection results.

In order to realize the speed and heavy load of railway wagons in China, to achieve safe production and environmental protection, to create a green enterprise, to reflect the health and safety of cherish employees, the safety and environmental protection of process equipment has become more and more important. We believe that safe and environmentally-friendly process equipment will surely become one of the future development directions in this field.

Custom Aspheric Lenses

Precision Aspheric Lenses are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing the output of a laser diode. Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.
