Abstract

In the aeration structure of the Bulb unit tubular pump that the utility model provides, bulb housing is also provided with ventilation duct, and ventilation duct is in communication with the outside through flow channel.First be that special vent passages is set, optimize the circulation of air in bulb housing, be beneficial to bulb housing inside to keep dry, reduce the corrosion and damage of internal unit parts, thus improve the working life of equipment, also the maintenance cost of equipment can be reduced, secondly, be provided with a lot of equipment in bulb housing, the position of ventilation will adjust according to the concrete condition of the mounting arrangements of internal unit, in most cases, good aeration-drying can be realized at the middle part of bulb.

Description

The aeration structure of Bulb unit tubular pump

Technical field

The utility model relates to through-flow pump technical field, is specifically a kind of aeration structure of Bulb unit tubular pump.

Background technique

In use there is following problem in conventional Bulb unit tubular pump: because this pump itself works for a long time under water, in the environment of humid, pump case is inner only has fan to carry out ventilation ventilation in inside usually, but, due to the structure that pump case self is comparatively closed, this draft type effect is unsatisfactory, pump case inner ventilation is not smooth, humidity is very large, a large amount of globules can be condensed on pump case, to the parts of pump case inside, the corrosion impact of the equipment such as pipeline and wire is large especially, the working life of equipment can be had a strong impact on, the working service cost compare of equipment is large.

Model utility content

Technical problem to be solved in the utility model is, provides a kind of ventilation effect good, is beneficial to the aeration structure of the Bulb unit tubular pump reducing maintenance cost.

For solving the problems of the technologies described above, the aeration structure of the Bulb unit tubular pump that the utility model provides, it comprises flow channel, bulb housing, and described bulb housing is also provided with ventilation duct, and ventilation duct is in communication with the outside through flow channel.

Described ventilation duct is positioned at the medium position place of bulb housing.

The upper end-hole of described ventilation duct is provided with dust proof plate, and dust proof plate is arranged on the top of upper end-hole through pillar.

After adopting above structure, the utility model compared with prior art, has the following advantages:

First be that special vent passages is set, optimize the circulation of air in bulb housing, be beneficial to bulb housing inside to keep dry, reduce the corrosion and damage of internal unit parts, thus improve the working life of equipment, also the maintenance cost of equipment can be reduced, secondly, be provided with a lot of equipment in bulb housing, the position of ventilation will adjust according to the concrete condition of the mounting arrangements of internal unit, in most cases, good aeration-drying can be realized at the middle part of bulb.

Fig. 2 is the structural representation of ventilation duct upper end-hole in the aeration structure of the utility model Bulb unit tubular pump;

Fig. 3 is the structural representation of upper cover plate in the aeration structure of the utility model Bulb unit tubular pump.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

With reference to shown in Fig. 1, Fig. 2, Fig. 3, the aeration structure of the utility model Bulb unit tubular pump, it comprises flow channel 1, bulb housing 2, in bulb housing 2, be provided with a lot of parts, equipment, such as motor, rotating shaft and radiation fan etc.

Feature of the present utility model is also provided with ventilation duct 3 at bulb housing 2, and this ventilation duct 3 is in communication with the outside through flow channel 1, and bulb housing 2 inside is in communication with the outside.

Preferably, ventilation duct 3 is positioned at the medium position place of bulb housing 2, can realize ideal ventilation effect to greatest extent.

For preventing extraneous dust or other foreign material from falling in bulb housing 2 from ventilation duct, be provided with dust proof plate 4 in the upper end-hole 6 of ventilation duct 3, dust proof plate 4 works as by bolt the top that pillar 5 is arranged on upper end-hole 6.
