Description

A kind of New type water pump noise reduction shock insulating foundation

Technical field

The utility model relates to heating equipment technical field, especially a kind of New type water pump noise reduction shock insulating foundation.

Background technique

In the prior art, with the high speed development of national science technology and economic construction, expedite the emergence of out a large amount of novel writing buildings, The modern architectures such as High-tech Research And Development base, star hotel, museum, large sized commercial center and condo, but it is incident It is the corollary equipment of plumbing, central air conditioner system, also becomes increasingly conspicuous on the influence of the noise and vibration of building internal and external environment.People To living and working environment require continuous improvement, to building interior environmental amenity degree require it is even more higher and higher.Especially It is that the vibration that all kinds of water pump machines of installation and power device generate in building can be transmitted in building by building element The each region in portion can also cause noise and pass through space radiation pollution environment, make one to feel tired and uncomfortable.

Existing water pump noise reduction shock insulation principle as shown in Figure 1, on concrete bed 1 be arranged spring vibration-isolator 2, use steel The both ends of water pump bracket 3 are fixed on spring vibration-isolator 2 by structure fabrication water pump bracket 3 through bracket 4, and water pump 5 is placed in water It pumps on bracket 3, so that the vibration of water pump is cut down by spring vibration-isolator, above structure needs to assemble spring vibration-isolator, structure Complexity, manufacture is difficult, and needs periodically to safeguard spring vibration-isolator, higher cost.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of structures, and New type water pump simple, that maintenance cost is cheap drops It makes an uproar shock insulating foundation.

In order to solve the above technical problems, New type water pump noise reduction shock insulating foundation provided by the utility model, comprising: concrete bottom Seat, at least one water pump, the bottom end of the water pump are cast on the concrete bed, setting and the concrete bottom on ground Seat compatible accommodation groove is laid with mineral wool on the bottom wall of the accommodation groove, multiple rubber pads is placed on the mineral wool, described mixed The lower end surface of solidifying soil pedestal is laid with polyethylene film, when so that the concrete bed being placed in the accommodation groove, concrete bottom Noise reduction shock insulation is carried out by polyethylene film, rubber pad, mineral wool between seat and ground.

Further, plastic cement sound insulationg board is set between the concrete bed side wall and the accommodation groove inner wall, enhances noise reduction Damping effect.

The technical effect of utility model: (1) the New type water pump noise reduction shock insulating foundation of the utility model, relative to existing skill Art, water pump and the molding of concrete bed formed by integrally casting, without spring vibration-isolator, reduce costs, reduce spring vibration isolation The maintenance of device；(2) concrete bed is placed in accommodation groove, and polyethylene film, rubber pad and mineral wool are arranged between ground, So that concrete bed is completely isolated with ground, there is no directly contacting, noise reduction damping effect is obvious；(3) rubber sound insulationg board Setting avoids vibration and noise from being directly delivered to ground, improves noise reduction damping effect.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawings of the specification:

Fig. 1 is the water pump noise reduction isolation structure schematic diagram of the prior art；

Fig. 2 is the structural schematic diagram of the water pump noise reduction shock insulating foundation of the utility model；

Fig. 3 is the top view of Fig. 2.

In figure: concrete bed 1, mineral wool 11, rubber pad 12, polyethylene film 13, plastic cement sound insulationg board 14, spring vibration isolation Device 2, water pump bracket 3, bracket 4, water pump 5, pump water inlet 51, pumping line 52, ground 6.

Specific embodiment

As shown in Figure 2 to Figure 3, the water pump noise reduction shock insulating foundation of the present embodiment includes concrete bed 1 to embodiment 1, this is mixed 4 water pumps 5 with pump water inlet 51 and pumping line 52 are arranged in formed by integrally casting on solidifying soil pedestal 1；It is arranged one on ground 6 A accommodation groove compatible with concrete bed 1 is laid with a thickness of 50mm, bulk density 48Kg/m on the bottom wall of accommodation groove³From Heart mineral wool 11 places the rubber pad 12 that multiple specifications are 50*50*50mm (long * wide * high), rubber pad 12 on the mineral wool 11 It can be uniformly arranged according to the size of accommodating groove bottom wall, the lower end surface of concrete bed 1 is laid with polyethylene film 13, so that mixed When solidifying soil pedestal 1 is placed in accommodation groove, by polyethylene film 13, rubber pad 12, mineral wool between concrete bed 1 and ground 6 11 carry out noise reduction shock insulation.

Preferably, the plastic cement sound insulationg board 14 with a thickness of 50mm is set between 1 side wall of concrete bed and accommodation groove inner wall, So that being isolated between accommodation groove inner wall by plastic cement sound insulationg board 14 around concrete bed 1, concrete bed 1 and accommodation groove Bottom wall is isolated by polyethylene film 13, mineral wool 11, it is ensured that concrete bed 1 and ground 6 are completely isolated, and there is no direct Contact, noise reduction damping effect are obvious.

Obviously, above-described embodiment is merely examples for clearly illustrating the present invention, and is not to this reality With the restriction of novel embodiment.For those of ordinary skill in the art, may be used also on the basis of the above description To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.And these Belong to the spiritual changes and variations that derived from of the utility model still in the protection scope of the utility model Among.
