Problems solved by technology

[0004] However, a disadvantage in plastic tanks against the advantages of corrosion resistance, low weight and ease of molding is that the production of joints for conducting fluids over openings in the walls of containers or tanks made of plastic poses difficulties
Due to the physical properties of plastics there is the danger that deformations in the area of ​​the opening due to sealing forces and temperature effects can lead to leaks between the plastic housing and the attached elements, even with expensive sealing elements

Embodiment Construction

[0019] Figure 1 shows the upper region of a container in the form of a plastic box 1, which is formed by a known method of rotomolding (see Schaab / Stoeckhert's "Guidelines for Plastics Processing Machinery", pages 561-564) from a machine suitable for relatively Manufacture of plastic material for large containers. In the process of rotomolding, a hollow body 5 formed in the form of a cylinder is molded in the plastic wall 3, so that the hollow body 5 abuts against the opening 9 in the wall 3 of the box body 1 with its upper end 7 in the figure. inside. In the example shown in the figure, the end 7 of the hollow body 5 protrudes slightly outside the wall 3, wherein a sealing ring 11 is arranged on this protruding end, which cooperates with a closing element in the form of a screw cap 13 to enable A tight seal and thus a seal of the opening 9 of the container wall 3 is achieved at the end 7 of the hollow body 5 concerned.

[0020] The cover 13 has a threaded part in the form o...

Abstract

A software system that uses the rigor and rules of business process automation to capture and structure organizational expertise, processes, and procedures-the non-automatable activities and actions of an organization-into a single, common, enterprise-wide, information framework. The capture function is engineered for usability and structured to reflect the patterns and semantics of business users rather than imposing software or process terminology. The produced framework generates a process-driven, centralized taxonomy of information and resources as business requirements are captured. The framework delivers users an organization-specific context to activities and information to be used for learning, training, reference, improvisation, collaboration, and operations. Said system has application in disseminating policies, procedures and compliance; business continuity; improved productivity and culture; training and learning; increasing the return on existing and requirements gathering for future IT investments; employee attrition, retention, and onboarding; capturing and managing knowledge and intellectual capital; and continuous improvement and process reengineering.

Description

technical field [0001] The invention relates to a fitting for forming a fluid-conducting connection at an opening in the wall of a plastic container, in particular a tank containing a fluid, especially a hydraulic fluid. Background technique [0002] Plastic tanks are often used in hydraulic systems to contain hydraulic fluid. Due to the possibility of simpler molding, low weight and corrosion resistance, plastic housings are widely used especially in hydraulic systems of working machines such as excavators, wheel loaders and the like. [0003] Such tanks are usually produced by known rotomolding or blow molding methods, wherein for larger containers, such as tanks for hydraulic fluids, plastics such as PE (polyethylene) or PA (polyamide) are used. ). [0004] However, a disadvantage of plastic tanks against the advantages of corrosion resistance, low weight and ease of molding is that the manufacture of fluid-conducting connections at openings in the walls of containers o...
