Abstract

PURPOSE:To carry out an installation work efficiently and accurately in installing facilities comprising a plurality of pumps and pipes by constituting a plurality of pump units with pumps and pipes arranged on a frame body, and connecting the pump units to each other at a work site. CONSTITUTION:In installing facilities comprising a plurality of pumps 8 and the pipes 6 thereof in the machine room of a building, the whole of the facilities are preliminarily divided into a plurality of constituent portions. Namely, the pipes 6 are housed within a frame body 5, and the pumps 8 are placed on the frame body 5 via a vibration-proof rack 7, thereby manufacturing a plurality of pump units in a factory in advance. In addition, a grating 9 as scaffolding is laid above the frame body 5 and a handrail 10 is added thereto. Thereafter, each pump unit is delivered to an installation work site and the pipes 6 thereof are connected to each other, thereby completing the installation work. According to the aforesaid construction, the installation of the whole facilities can be carried out efficiently and accurately.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pump installed in an air conditioning heat source machine room of a building or the like and a method of constructing piping equipment around the pump.

(Prior art) Pumps and piping equipment around the pumps are installed in air conditioning heat source equipment rooms such as buildings where refrigerators and heat exchangers are installed. The piping equipment will also be large-scale. Conventionally, when constructing large-scale pumps and piping equipment around pumps (for example, 20 or more pumps), all of the pumps, piping materials, and other components must be brought to the construction site, and site workers must Processing and installation were carried out on the spot.

[Problem to be solved by the invention]

However, when constructing large-scale pumps and piping equipment around pumps, it is necessary to install high-density, three-dimensional piping and pumps in a precise order within a limited site space, so conventional construction methods cannot be used.

The problem was that the accuracy and quality of processing and installation depended on the skill level of the on-site workers, making it impossible to always achieve a constant quality of construction. Further, a large amount of work time and a large number of workers are required at the site, resulting in a problem that the construction period at the site becomes long and the safety of the site work cannot be ensured.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and its purpose is to always achieve a constant quality of construction regardless of the skill level of site workers. Time and labor can be saved. The purpose of the present invention is to provide a construction method for a pump and piping equipment around the pump.

[Means to solve the problem]

In order to achieve the above object, the method for constructing the pump and the piping equipment around the pump of the present invention is to divide the entire pump and the piping equipment around the pump into a plurality of component parts in advance before on-site construction, and for each component part, at least the piping The present invention is characterized in that a pump unit is produced in a factory, in which a pump is disposed in a frame body, and a pump is fixed on the frame body via vibration isolating means, and then the plurality of pump units 7 are connected on-site.

[Example] The present invention will be explained below based on the illustrated example. FIG. 1 is an overall plan view of a pump and piping equipment around the pump to which the construction method of the present invention is applied.

FIG. 2 is a longitudinal sectional view showing an example of the pump unit.

Therefore, the pump and piping equipment around the pump in this embodiment are 4.
Construction is carried out by connecting two pump units 1, 2, 3 and 4. As shown in FIG. 2, these pump units 1, 2, 3, 4 are provided with piping 6 in a frame 5 made of metal steel, and on the frame 6 are provided with vibration-proof A pump 8 placed on a vibration isolating frame 7 as a means is fixedly installed. In addition, because of this vibration-proof pedestal 7, the pump 8
It is possible to prevent vibrations from the pipe 6 from being transmitted to the pipe 6. In addition, a grid-like grating 9 is laid on the top surface of the frame 5 of the pump unit to serve as a foothold, and a handrail 10 is also attached. A person can walk on the frame body 5. Further, an elevating staircase 11 is also attached to the pump unit 1 and the pump unit 4.

Note that the pump unit 1.2.3.4 may be formed by incorporating various instruments such as a ground pressure gauge, a hesider for distributing and taking out cooling water, etc. to each system.

To explain the implementation procedure of the construction method of the present invention in this example, first, the pump to be constructed and the entire piping equipment around the pump are divided into four component parts, and each component has a pump unit with the above structure. 1.2,3.
4 is manufactured in advance in a factory. In this way, since the pump 8, piping 6, etc. are processed and installed at the factory, it is possible to use large machine tools, and the accuracy and quality of the processing and installation of the pump 8, piping 6, etc. can be maintained at a constant level. It also becomes possible to mass produce pump units 1, 2, 3.4.

Once the pump units 1, 2, 3.4 are completed, they are transported to the construction site (mechanical room of the building), and the piping 6 between the pump units is connected to complete the construction. In this case, the work at the construction site is only the connection of the piping 6 between the pump units, and most of the processing and installation of the pump 8, piping 6, etc. is done at the factory, where the pump units 1, 2, 3.4 are manufactured. Since it is done in detail, on-site work can be greatly simplified, and as a result, one work time and the number of workers can be saved.

〔Effect of the invention〕

The present invention has one or more configurations and functions, and there is no need for field workers to process and install component parts such as pumps and piping materials on-site, unlike in the past.

As a result, construction can always be of a constant quality, regardless of the level of skill of the on-site workers.

Further, since the pump is fixedly installed on the frame via the vibration isolating means, it is possible to prevent vibrations of the piping from being transmitted to the pump.

Furthermore, on-site work can be completed by simply connecting multiple pump units, greatly simplifying on-site work.
As a result, the work time and number of workers at one site can be saved.
