Description

A kind of switch type cooling unit of water pump bearing lubricant oil

Technical field

The utility model relates to water pump, particularly the switch type cooling unit of water pump bearing lubricant oil.

Background technique

During pump operation, bearing easily generates heat, and existing bearing oil switch type cooling structure is: Bearing and lubrication oil is in a cavity; Larger cavity of outer wrap, logical one continues cooling water of flowing between two cavitys, with the lubricant oil heat-shift to reduce bearing temperature.

When this cooling unit was used in MODEL VERTICAL MULTISTAGE PUMP, radial dimension can excessive, bearing cooling effect deficiency, easily damage.

Therefore, the cooling unit of the better bearing oil of a kind of cooling effect is badly in need of in pump technology field, particularly MODEL VERTICAL MULTISTAGE PUMP field.

Summary of the invention

The utility model provides a kind of switch type cooling unit of water pump bearing lubricant oil of better effects if for the defective that switch type cooling unit radial dimension is excessive, cooling effect is not enough of existing water pump bearing lubricant oil.The technological scheme that the utility model adopts is as follows:

A kind of switch type cooling unit of water pump bearing lubricant oil comprises bearing support, bearing cap, axle, bearing, it is characterized in that,

Be fixedly connected with support on this bearing support;

This bearing coils cooling tube outward;

This cooling tube outside connection ring-type cooling fin;

This cooling tube and this cooling fin are placed on this support;

Have two through holes on this bearing support, feed-water end and the waterexit end of this cooling tube is set respectively.

The switch type cooling unit of a kind of water pump bearing lubricant oil as above wherein, inserts a temperature measuring element in this bearing.

The utility model radial dimension is little, compact structure, economical with materials; Cooling even, rate of cooling is fast; The cavity casting is more simple, convenient.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is the structural representation of the switch type cooling unit of the utility model water pump bearing lubricant oil.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Fig. 1 shows structure of the present utility model.Bearing support 1 forms a cavity with bearing cap 2, and the outer socked shaft of axle 7 of water pump holds 8, is located in this cavity.Be lubricant oil in cavity.

In cavity, be fixedly connected with a support 6 on bearing support 1, be fixedly connected with and be welding, screw-nut connection etc.

The outer coiling cooling tube 4 of bearing 8, cooling tube 4 outside welding ring-type cooling fins 5.Cooling tube 4 and cooling fin 5 are placed on support 6, have two through holes on bearing support 1, and feed-water end and the waterexit end of cooling tube 4 is set respectively.

So cooling tube 4 and cooling fin 5 are outer is lubricant oil.

In the pump operation process, bearing 8 produces heat, relies on the cooling tube 4 of coiling, and the outer cooling fin 5 of cooling tube 4, has sufficient exchange heat between lubricant oil and cooling water, guarantees lower bearing temperature.

In one of them embodiment of the present utility model, temperature measuring element 3 inserts bearing 8, measures in real time the temperature of bearing 8.

Compared with prior art, this bearing oil switch type cooling structure has following advantage:

1, this bearing oil switch type cooling structure is compared the cooling requirement that existing switch type cooling structure better meets bearing, and cooling even, rate of cooling is fast.

2, compare existing switch type cooling structure, this switch type cooling structure has been cancelled a cooling chamber, and its radial dimension reduces, and saves material.

3, the casting of the cavity of this switch type cooling structure is more simple, convenient.

Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
