How do newbies learn hydropower materials?

According to my experience, start with the decoration of hydropower to learn faster, because the decoration cycle is short, although the sparrow is small, can quickly master the pipe, wiring, equipment, familiar with materials, can quickly form the actual concept of installation, this stage can go to the hydropower construction certificate (textbooks have electrical, water supply and drainage basic knowledge, construction technology, basic map), you can also buy some hydropower introductory books to see, there is a year or two after you can do engineering hydropower, such as residential buildings and comprehensive buildings, engineering hydropower has formal drawingsThe system is complete, the construction requirements are standardized, the construction process, engineering drawings, and the mastery of the specifications will be greatly improved, this process will take 3 5 years, at this time you can go to the mechanical and electrical first-class constructor, cost engineer and other certificates (to have a college diploma in construction), to the direction of engineering management, engineering cost to work hard. When doing engineering installation, it is best to find an installation person in charge or a master with an installation class, do not expect him to teach you anything, I hope he can give you a job involving different types of work and different content when dispatching, and learn a little more in a short time, including management experience. Because when you are doing a large-scale project, you have no relationship, you don't work hard, and you can't get the approval of the leader, and you may repeat the work of piping, making holes, digging grooves, screws, and painting for a year.

This is what every hydropower master must master, and it is also the direction of every apprentice's growth.

When looking at the water drawing, you must look at the plan and the system diagram, so that you can know where the pipeline is turning, where to change the diameter, where to distribute the water point, what is the elevation of the water distribution point, and when looking at the water supply, we should see if there are corresponding drainage measures and water facilities, and then consider whether the water supply point and drainage measures, water facilities are reasonable, if there is a washing machine water supply point, under normal circumstances, the water supply point elevation distance from the ground is completed, and then see if there is a drainage floor drain of the washing machine, is it a special washing machine floor drain, whether there is a water trap, these are there to see if there is a power socket for the washing machine, whether the location is reasonable, whether the socket safety height, safety measures. To look at the water diagram, you must have a strong sense of three-dimensional space, and you must feel that you are standing in the room and following the pipe.

First look at the drawing catalog, have a preliminary understanding of the number and content of the drawings, and find out the electrical drawings you want to see. Look at the electrical design description and specification sheet to understand the design intent and the meaning of the various symbols. Look at various drawings in order, understand the content of the drawings, and combine the system diagram and the floor plan to clarify the meaning, and read the floor plan in order according to the room when looking at the floor plan, understand the direction of the line, equipment and devices such as lamps, bolts, machinery, etc.

After mastering the content of the construction drawings, the production and installation can be carried out.

Hydropower construction drawings must be able to understand and have general on-site construction knowledge. Basic procedures for hydropower data: drawing review, design changes; construction plan (included in the general overall plan, and must be prepared for separate contracting); Commencement report (ibid.); Materials are submitted for review; process acceptance; Concealed engineering inspection (test, inspection data); Decoration stage installation (wires, accessories, appliances and equipment, etc.); Relevant functional tests and inspections (water, electricity, operation of appliances and equipment, resistance, insulation, grounding, ball, water pressure, washing, etc.); Improve the relevant process inspection data (water and electricity stage); fire HVAC integrated wiring and other parts (most of them are prepared by the subcontractor itself); Prepare as-built drawings and sort out as-built materials; Acceptance by the quality supervision department; Organize and hand over archives.

According to the requirements of the design task, the construction drawings of building water supply and drainage shall include the general layout plan, building plan, system drawing, construction details, design and construction instructions and main equipment and material tables. The water supply and drainage plan should express the layout of the water supply and drainage pipelines and equipment. The internal water supply and drainage of the building is determined by the selected water supply and drainage method to determine the number of floor plans.

The ground floor and basement must be painted; If there is equipment such as a water tank on the top floor, it must also be drawn separately; A standard floor plan can be drawn for the middle floors of the building, such as sanitary or water appliances of the same type, number and location, otherwise, they should be drawn layer by layer.

Several types of pipes can be drawn on a plan, and if the pipeline is complex, they can also be drawn separately, based on the principle that the drawings can clearly express the design intent and the number of drawings is relatively small. Pipelines and equipment should be highlighted in the plan, that is, thick lines should be used to represent pipelines, and the rest should be thin lines. The scale of the floor plan is generally consistent with the architectural plan, and the commonly used scale is 1:

100。It is beneficial to keep this knowledge point in mind, and it is not easy to have problems in the operation of newcomers.

When novices look at the structural beams, whether the size of the embedded casing is reasonable, what is the building elevation, and whether the height of the room is affected after the installation of hydropower facilities. Room size, wall size, raft thickness, screed thickness, insulation whether it is internal insulation or external insulation, insulation layer thickness, interior and exterior wall decoration layer thickness, when these data are available, can be accurately embedded, reserved, and processed.

The water supply and drainage plan should express the following contents: the type, quantity, and location of water use rooms and water equipment; Pipes, pipeline accessories, sanitary appliances, and water equipment of various functions, such as fire hydrant boxes, sprinkler heads, etc., should be represented by legends; The diameter and slope of various horizontal trunk pipes, risers, and branch pipes should be marked; Each pipeline should be numbered. It can be seen at a glance for newbies.

I am Wang Bin, the founder of Caliper Hydropower, and I hope my sharing can help you.

There is not much room for choice at the age of 40, and if you have no education, you can consider plumber technology.

This is the situation of learning hydropower now, you can refer to it.

When I was 20 years old, I sprayed primer in a furniture factory in Pingshan Town, Shenzhen, and worked until I came home at the age of 25 and got married. With a wife and children to take care of, I can't go out to work anymore, so I paint in a small furniture store in my hometown.

There are many harmful substances in the paint, often in such an environment, gradually I feel unwell, decided to change careers, just my brother opened a water and electricity installation shop, urgently short of manpower, asked me to help, so I changed from a painter to a plumber, this year, I was 38 years old.

Eighteen years have passed, and I have my own plumbing and electrical materials sales department, wholesale and retail, construction and maintenance, and the business is rising step by step.

Saying this, it doesn't seem to match the subject's question, don't worry.

Three years ago, a young man who graduated from a technical school came to my shop, saying that he was majoring in hydropower and that he knew how to theoretical, and wanted to come to me as a plumber and practice well. I gladly accepted this apprentice.

The apprentice is willing to learn, has strong hands-on ability, and makes rapid progress.

Half a year later, he can basically work alone, working with water and electricity. And the blue is better than the blue, and I secretly admire the teacher.

A year later, with the support of a relative, he opened a store in the county building materials market, with water and electricity installation, kitchen and bathroom, and the business was booming

Let's talk about an older guy who works as a security captain in a company in Beijing and earns a considerable income. Later, I don't know what happened, I couldn't come back, so I had to work in my store.

I am not a traitor, I know everything, I teach by word and deed...Now, I recommend him to work as an installer in a friend's kitchen and bathroom shop, earning 300 yuan a day.

In fact, plumbers and electricians, like other types of work, can be champions, can earn money, as long as you have the heart, willing to learn and willing to do not be lazy, support your family or a slight surplus, and then work hard, be a small boss or contractor, build a house to improve the standard of living, or can.

At present, in any city, it is possible to learn plumber technology.

There are now 4 paths to learn plumber technology that can be taken. The choice is yours.

The first. Find acquaintances and friends to introduce the hydropower master to learn from him. The study time is at least half a year to more than one year to become a master.

The second. I went to his construction site with my brother and friend to do small work and entered the industry to study. The minimum study time is 2-3 years to become a master.

The third way is to find news such as apprentices through the Internet group, go to the boss to talk to, and learn from him. The study time is at least half a year to more than one year to become a master.

It's all of the above. In the past, you learned three ways of hydropower, and you have to work hard to achieve such a result.

Steps to get started as an electrician:

Step 2: Choose how you want to enter the industry. At present, there are 4 ways to learn hydropower, which have been discussed in detail earlier. The way you enter the industry directly determines how long you can learn to erect reeds.

Step 5: Caliper water fiber or electrical practical technology apprentices have basically learned almost everything in 2 months, and they will do the work by themselves.

Plumbers look simple, but in fact, it is not easy to do. Especially.

In order to adapt to the market, it is necessary to make the work have a certain cost performance in order to get the living family. Therefore, the first thing to emphasize is to be proficient in learning and doing.

Plumbers should at least know the relationship between the water and electricity of the rough house and the water and electricity needed by the owner, so as to have a reasonable plan on the whole.

It is necessary to know the use of the latest hydropower materials on the market, methods, prices, transportation, storage, specific operation, installation and dismantling, etc. Not only do you have to go home often, but you also have to visit the market often.

It is very important to pay a return visit to the construction site after the work, know how the work you do is seen by the owner, and not be afraid of losing face even if it is defective.

It is important to pay attention to what kind of home you have already lived, especially in terms of water and electricity, which is a performance of testing your work for a long time after installation, and also preparing for the opportunity to renovate water and electricity in the future. Don't underestimate the renovation, the profit is not worse than the decoration of the new house, but the technical requirements are actually higher, some people do the renovation work is a loss in the demolition of old water and electricity, those pipes or something aging are almost broken at a touch, not easy to do, so the demolition is also technology.
