Description

Self-priming pump drainage system of diesel engine

Technical Field

The utility model relates to a diesel engine self priming pump technical field, concretely relates to diesel engine self priming pump drainage system.

Background

A drainage system in water conservancy engineering is an engineering which is built for controlling and allocating surface water and underground water in nature to achieve the purposes of removing harm and benefiting. The water flow can be controlled by building a drainage system, flood disasters are prevented, and water quantity is regulated and distributed to meet the requirements of people on water resources in life and production. In actual operation, need design drainage waterlogging system according to open sea tide level, drainage waterlogging water level condition, guarantee a plurality of pump stations and move in coordination, guarantee drainage waterlogging safety. Among the prior art, diesel engine pump unit need install the bottom valve additional in inlet line suction pool department when the condition of absorbing water from the low, before the pump starts, closes the bottom valve, toward filling water in the pump, just can start after the air drains cleanly, consequently is loaded down with trivial details to the operation control of a plurality of pump stations.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an easy operation's diesel engine self priming pump drainage system.

The technical scheme of the utility model is that: the utility model provides a diesel engine self priming pump drainage system, includes the pump station that is used for placing diesel engine self priming pump that a plurality of groups set up side by side, draws the water pipe way including the inlet tube of connecting inlet channel or groundwater and diesel engine self priming pump, connecting the drain pipe of diesel engine self priming pump and river, and the inlet tube passes through the hose connection with the water inlet department of diesel engine self priming pump, and the drain pipe communicates to the river behind the dykes and dams.

According to the further technical scheme, the drain pipe penetrates through the dam and is communicated to the river, and the drain pipe is located between pipelines in the dam and is connected through the hose.

Further technical scheme, the drain pipe passes through the overhead setting in the top of dykes and dams of support frame.

According to the further technical scheme, the diesel engine self-priming pump comprises a motor vehicle braking air compressor coaxially connected with a diesel engine, and a gear of the diesel engine is embedded into a groove of a shaft end disc of the air compressor.

The utility model has the advantages that:

the utility model discloses simple structure through pump station, the water-drawing pipeline that the multiunit set up side by side to improve holistic water-drawing effect, whole drainage system is suitable according to the local conditions, and water-drawing pipeline's drain pipe passes through the support frame and makes somebody a mere figurehead on dykes and dams or gets through behind the dykes and dams drainage pipe and passes therefrom, avoids producing the influence to the pedestrian. The air compressor machine of the diesel engine self priming pump that sets up in the pump station is through the diesel engine gear drive of linkage to overcome among the prior art toward pump in water, the air drain can the defect that just can start after clean.

Drawings

Fig. 1 is a schematic structural view of embodiment 1 of the present invention;

FIG. 2 is a schematic sectional view taken along line A-A of FIG. 1;

fig. 3 is a schematic structural view of embodiment 2 of the present invention;

fig. 4 is a schematic structural view of the self-priming pump of the middle diesel engine of the present invention.

The system comprises a pump station 1, a pump station 2, a water drawing pipeline 21, a water inlet pipe 22, a water outlet pipe 3, a hose 4, a dam 5, a water inlet channel 6, underground water 7, a river 8, a diesel self-priming pump 81, a diesel engine 82 and an air compressor.

Detailed Description

The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.

The utility model relates to a diesel engine self priming pump drainage waterlogging system, as shown in fig. 1-4, including pump station 1, the water drawing pipeline 2 that is used for placing diesel engine self priming pump that a plurality of groups set up side by side, diesel engine self priming pump 8 includes motor vehicle braking air compressor machine 82 with the coaxial hookup of diesel engine 81, in the recess of diesel engine 81's gear embedding air compressor machine 82 axle head disc. The air compressor 82 is driven by the gear of the diesel engine 81 in linkage, and the operation is simple, so that the defect that the pump can be started after water is filled into the pump and air is drained in the prior art is overcome.

The water drawing pipeline 2 comprises a water inlet pipe 21 connected with a water inlet channel 5 or underground water 6 and a diesel self-sucking pump 8, and a water discharge pipe 22 connected with the diesel self-sucking pump 8 and a river 7, wherein the water inlet pipe 21 is connected with the water inlet of the diesel self-sucking pump 8 through a hose 3, and the water discharge pipe 22 is communicated to the river 7 through a dam 4.

Example 1: as shown in fig. 1, a drainage pipe 22 is connected to the river 7 through the dike 4, and the drainage pipe 22 is connected between the pipes in the dike 4 through a hose 3, so that the sedimentation in the dike 4 is prevented, and the pressure in the pipes is prevented from being too high, thereby damaging a drainage line.

Example 2: as shown in fig. 2, the drain pipe 22 is arranged above the dam 4 via a support frame, so as to avoid affecting pedestrians and vehicles.

To sum up, the utility model discloses simple structure through pump station, the water-drawing pipeline that the multiunit set up side by side to improve holistic effect of drawing water.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
