Abstract
The utility model discloses a kind of cooling structures of Roots vaccum pump, including the pump housing, the pump housing is equipped with pump chamber and grease chamber, pump chamber two sides are grease chamber, midfeather is equipped between the pump chamber and grease chamber, the midfeather lower sides are equipped with water inlet, and midfeather upper portion side wall is equipped with water outlet, is equipped with interlayer cooling chamber inside the midfeather.The utility model compared with prior art the advantages of be: the cooling structure of the utility model can substantially reduce the heating of vacuum pump, thus block pump chamber generate heat enter grease chamber.
Description
Technical field
The utility model relates to vacuum pump more particularly to a kind of cooling structures of Roots vaccum pump.
Background technique
The type of cooling of existing Roots vaccum pump is cooled down in grease chamber by cooling coil, and cooling is insufficient, can not be hindered
The heat that disconnected pump chamber generates enters grease chamber.Therefore, research and develop it is a kind of can be effectively reduced vacuum pump heating Roots vaccum pump it is cold
But structure becomes those skilled in the art's urgent problem to be solved.
Summary of the invention
The utility model is to provide a kind of cooling structure of Roots vaccum pump to solve above-mentioned deficiency.
The above-mentioned purpose of the utility model is realized by technical solution below: a kind of cooling knot of Roots vaccum pump
Structure, including the pump housing, the pump housing are equipped with pump chamber and grease chamber, and pump chamber two sides are grease chamber, are equipped between the pump chamber and grease chamber
Partition, the midfeather lower sides are equipped with water inlet, and midfeather upper portion side wall is equipped with water outlet, is equipped with inside the midfeather
Interlayer cooling chamber.
Further, the interlayer cooling chamber include be interconnected and be connected to water inlet, water outlet left side water flow passage,
Midfeather upper runner, right side water flow passage and midfeather lower flow channel.
When work, cooling water is entered by water inlet, is separately flowed by left side water flow passage, midfeather upper runner, right side water
Runner and midfeather lower flow channel are finally flowed out from water outlet.Its working principle is that Roots vaccum pump is at runtime, interior generate is pumped
The heat of compression directly pass through the interlayer cooling chamber in midfeather and blocked, the conduction of heat directly in reduction pump chamber.
The utility model compared with prior art the advantages of be: the cooling structure of the utility model can substantially reduce vacuum pump
Heating, thus block pump chamber generate heat enter grease chamber.
Detailed description of the invention
Fig. 1 is the exterior lateral sides structural schematic diagram of the utility model.
Fig. 2 is the schematic diagram of internal structure of the utility model midfeather.
Specific embodiment
The utility model is described in further detail below with reference to embodiment.
As shown in Figure 1 and Figure 2, a kind of cooling structure of Roots vaccum pump, including the pump housing, the pump housing are equipped with pump chamber and oil
Room, pump chamber two sides are grease chamber, and midfeather 4 is equipped between the pump chamber and grease chamber, and 4 lower sides of midfeather are equipped with water inlet
Mouth 1, midfeather upper portion side wall are equipped with water outlet 2, are equipped with interlayer cooling chamber 3 inside the midfeather.
Further, the interlayer cooling chamber 3 includes the left side water flow for being interconnected and being connected to water inlet 1, water outlet 2
Road 3-1, midfeather upper runner 3-2, right side water flow passage 3-3 and midfeather lower flow channel 3-4.
When work, cooling water is entered by water inlet 1, separately flow by left side water flow passage 3-1, midfeather upper runner 3-2,
Right side water flow passage 3-3 and midfeather lower flow channel 3-4 is finally flowed out from water outlet 2.Its working principle is that Roots vaccum pump is being transported
When row, the heat of compression for pumping interior generation directly passes through the interlayer cooling chamber 3 in midfeather and is blocked, directly heat in reduction pump chamber
Conduction.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model specification and embodiment content, directly or indirectly use
In other related technical areas, it is also included in the patent protection scope of the utility model.
