Abstract
The utility model discloses a suspension style tangent fire pump. The suspension style tangent fire pump includes a pump body, an impeller, a pump cover and a mechanical seal, wherein the impeller is installed inside the pump body, the pump cover is arranged on the port of one end of the pump body, and the mechanical seal is arranged between the pump cover and the pump body. The suspension style tangent fire pump is characterized in that a suspension component is connected with the pump body. The damage to the pipeline from the overhigh pressure in the case of the water pump being started suddenly is avoided due to the fact that the characteristic performance curve of the water pump operation is a smooth curve of which the lift changes little when the flow increases so the pressure is uniform. The suspension style tangent fire pump is capable of meeting the performance requirement of water pump to the utmost and work reliably in the situation of sudden disaster.
Description
Technical field
The utility model relates to the water pump field, specifically, specially refers to a kind of tangent fire pumps that adopts the suspension-type design.
Background technique
Fire water pump as its name suggests, the pump of using in the fire-fighting, hermetically sealed with it, without leak, corrosion-resistant characteristics, the departments such as environmental protection, water treatment, fire-fighting that are widely used in are used for pumping each class I liquid I, being to create to use with the pump type of fire-fighting system all much the samely with pump without the ideal of leakages, pollution-free civilized workshop, civilized factory, is that lift has different with flow.The selection ground of fire water pump should be according to technological process, the plumbing requirement.
At present fire water pump generally adopts the straight connection type Ordinary Centrifugal Pumps to satisfy the fire-fighting requirement, easily causes the easy overlond running of water pump when higher to performance requirement, and using scope is limited.
The model utility content
The purpose of this utility model is to provide the suspension-type tangent fire pumps, replaces traditional straight connection type structure by the structural design that adopts suspension-type, has overcome the deficiency in the conventional art, thereby realizes the purpose of this utility model.
The technical problem that the utility model solves can realize by the following technical solutions:
The suspension-type tangent fire pumps comprises the pump housing, impeller, pump cover and mechanical seal, and the inside of the described pump housing is equipped with impeller, the port of the pump housing one end is provided with pump cover, be provided with mechanical seal between described pump cover and the pump housing, it is characterized in that, the described pump housing is connected with sprung parts.
In an embodiment of the present utility model, the neutral position of described sprung parts is provided with mounting hole, and the pump housing stretches into mounting hole by attachment post and sprung parts installs and fixes.
In an embodiment of the present utility model, the both sides of described sprung parts are connected with the pump housing by the bolt attaching nut.
The beneficial effects of the utility model are: the performance curve of water pump operation is one and increases lift with flow and change little smoothed curve, pressure is even, avoid because of the too high destruction that pipeline is caused of the unexpected breakout pressure of water pump, during in the face of sudden the condition of a disaster, can satisfy to greatest extent the performance requirement to water pump, and reliable operation.
Description of drawings
Fig. 1 is the structural representation of suspension-type tangent fire pumps described in the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, suspension-type tangent fire pumps described in the utility model, comprise the pump housing 100, impeller 110, pump cover 120 and mechanical seal 111, the inside of the described pump housing is equipped with impeller, the port of the pump housing one end is provided with pump cover, be provided with mechanical seal between described pump cover and the pump housing, the described pump housing is connected with sprung parts 200.
In an embodiment of the present utility model, the neutral position of described sprung parts is provided with mounting hole, and the pump housing stretches into mounting hole by attachment post and sprung parts installs and fixes.
In an embodiment of the present utility model, the both sides of described sprung parts are connected with the pump housing by the bolt attaching nut.
The suspension-type tangent fire pumps adopts suspension frame structure, forms the self-contained pump head part of unit, thereby so that water pump can adopt according to different performances the selection of Motor of different configurations, also satisfies the requirement of tangent fire pumps.The performance curve of tangent fire pumps is one and increases lift with flow and change little smoothed curve that therefore, the suspension-type tangent fire pumps can further enlarge the application area of water pump according to the option and installment power of motor.
The beneficial effects of the utility model are: pressure is even, avoids because of the too high destruction that pipeline is caused of the unexpected breakout pressure of water pump, during in the face of sudden the condition of a disaster, can satisfy to greatest extent the performance requirement to water pump, and reliable operation.
More than show and described basic principle of the present utility model and 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 the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, 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.
