Mechanical And Electrical installation Engineering requirements and issues needing attention
In everyday life, mechanical and Electrical l installation is required in many places. So what are the requirements for mechanical and Electrical l installation? What issues need to be paid attention to in the mechanical and Electrical l installation project? Next, the editor will introduce the requirements of Mechanical And Electrical installation Engineering and the problems that need attention, and I hope to help you. The specific requirements for Mechanical And Electrical installation Engineering and the issues that need attention are as follows.
Mechanical and electrical installation engineering requirements
1. The circuit breaker and its connection should be connected normally without clogging; the integral and closing instructions are correct; the auxiliary switch is correct and reliable.
2. Electrical connections should be in good contact.
3. The circuit is driven correctly.
4. The set value of the protection device is in compliance with the regulations; the operation and linkage test are correct.
5. Good grounding, there is a certain margin in the cable terminal, hanging cable standard, indicating cable start, terminal and cable specifications, length, etc.
6. The power head uses a heat shrinking process, and the cable head is controlled by a casing process. The number of cables and core ends is agreed to be typed using a computer typewriter, and the shielded cable shield is designed to be grounded. In any case, the cables cannot be placed in parallel under the heat pipe.
Mechanical And Electrical installation Engineering needs attention
1. Dark cloth line management problem. In the mechanical and Electrical l installation project, it is often involved in the problem of needing to draw the conduit from the floor. Therefore, when constructing the wall, it is necessary to carefully review the construction drawings, accurately locate the terminal box, and combine the corresponding construction documents. The owner requested the implementation of standardized construction operations.
2. Cross-work problems. In the construction of construction engineering, in the mechanical and Electrical l installation and construction, it often involves cross-operations, mainly referring to the cross-operation between civil engineering and renovation works. If the cross-operation problem cannot be properly handled during construction, it is easy to cause the front-end construction process to be ineffective. Connections have a serious impact on construction progress and efficiency. Under this circumstance, it is necessary to negotiate and communicate with the owners, contractors and civil construction parties, strengthen cooperation, and appropriately adjust the procedures to ensure that the construction progress is not delayed.
3. Large amount of engineering and wide cooperation. The construction project has the characteristics of complexity and system. In an engineering project, civil construction, decoration and mechanical and Electrical l construction often occur at the same time. At this time, the mechanical and Electrical l installation project needs to be coordinated with multiple project parties, and at the same time More professionals, and involving multiple majors, the amount of engineering has also increased.
4. Electrical pipeline management issues. The number of electrical pipelines is large, and the lines are long. Therefore, in the installation of electrical pipelines, the electrical pipelines should be neatly planned, and the stability and firmness of the brackets should be checked. In particular, pay attention to the bending radius of the conduits and the radius of the cable ducts. In accordance with the relevant standards, check whether the edge of the gate is smooth and horn-shaped, and pay attention to the seal protection after the cable operation is completed.
The above is about the requirements of Mechanical And Electrical installation Engineering and the issues that need attention. I hope that everyone understands the requirements of Mechanical And Electrical installation Engineering and the problems that need attention, and it is helpful to everyone.
