Abstract

The utility model has the name of a self-diversion device for a diesel engine water pump, and relates to a self-diversion device for a diesel engine water pump, which injects water into the water pump before the water pump starts. The self-diversion device mainly solves the problems that the water needs to be injected into the water pump before the water pump starts; in the traditional method, a vacuum pump provided with a large high water level water tank is adopted; a power supply is additionally adopted to drive the vacuum pump; the operation needs two or more persons, the overhaul cost is high; the operation is inconvenient; and the utility model discloses an air emptier for an diesel water pump, which has a complicated structure and can not be operated until an operator is trained. In the self-diversion device, an air inlet of an air compressor on a diesel engine is connected with a water outlet of the water pump through a pipeline, and a gate valve and a ball float valve are in series connection with the pipeline. In the self-diversion deive, only the water outlet is drilled on a water outlet pipe of the water pump, so as to be connected with the air inlet of the air compressor on the diesel engine, no change needs to be performed on the diesel engine, no auxiliary equipment is additionally adopted, and no person needs to be added, therefore, the self-diversion device has a simple structure and is convenient for operation.

Description

Diesel pump is from water diversion apparatus

Technical field

The utility model relates to a kind of diesel pump from water diversion apparatus, and the diesel pump that relates to water filling in the starting mode of pump forward direction water pump specifically is from water diversion apparatus.

Background technique

Diesel pump is made up of diesel engine, clutch and water pump, usually in use need be before startup (before the start) water filling in water pump (being commonly called as water) or install head-tank additional water can be poured in the water pump voluntarily, diesel engine could start and makes pump working after the fills with water in water pump.It is long etc. to tend to occur water intaking is inconvenient, bottom valve leaks, water filling is young water injection time in water pump in this process of water filling, and does not know to have annotated how much water actually, and needs at least that two people are above could to operate, and often once can not start success.Particularly particularly evident on the diesel pump of movable type.In order to address this problem traditional method is to utilize vacuum pump, increase personnel and bucket water storage or carry big elevated tank, frequent maintenance bottom valve, increase gate valve at water filling hole and enlarge water filling hole etc.But shortcoming is to need the personnel of electric drive vacuum pump, needs many, cost of overhaul height, inconvenient operation etc.Patent is 200620082280.6, name is called diesel engine suction pump air exhaust, what propose is provided with a cored screw on the water pump water outlet tube wall, the other end of cored screw is connected on filter and the two-way valve by pipeline, and the other end of two-way valve is connected on the sewage draining exit on the diesel filter by pipeline.During use, earlier with exit of pump and diesel filter suction port good seal, take off the blowdown flap on the filter cleaner again, two-way valve is fixed to the upper, start diesel engine, its suction tude is extracted air out; Water reaches the pump housing, and arrives in the two-way valve by filter, and the hollow valve body come-up makes B end in contact two-way valve housing, with valve closing; Again pipeline on the filter cleaner sewage draining exit is taken off, start water pump,, can make drawdown in the valve, hollow valve body A end in contact valve casing, the refluence of anti-sealing if pump water inlet bottom valve seal is bad.But this structure is more complicated also, and the personnel of general process training are not difficult to finish this work.

Summary of the invention

The purpose of this utility model is at above-mentioned deficiency, and provide a kind of simple in structure, do not need to increase supplementary equipment and personnel, the diesel pump of water filling that can solve diesel pump effectively is from water diversion apparatus.

Technical solution of the present utility model is that diesel pump is from water diversion apparatus: the air compressor air intake mouth on the diesel engine is connected with the water outlet of water pump by pipeline, series connection one gate valve and float valve in pipeline.

The utility model only need seal pump outlet when using, utilize the intakeport of the air compressor of installing on the diesel engine, the air that siphons away in the water pump by connecting pipeline makes it produce vacuum, water is owing to the atmosphere negative pressure in the water pump enters into water pump, thereby make to be full of water in the water pump and to reach starting condition, simultaneously float valve being installed on the inlet pipeline of water pump promptly has demonstration after water is filled.The utility model is because only need be boring an air compressor air intake mouth (sourceof negative pressure) on the Kong Rangqi connection diesel engine on the rising pipe of water pump, so structure is simple especially; Simultaneously since the starting point be not need to change diesel engine, do not need to increase supplementary equipment and personnel, so it does not have very special requirement to the mode of operation of diesel pump itself; Because diesel pump all is the clutch between diesel engine and the water pump of closing again after the fills with water in determining water pump, can know easily by seeing float valve whether water is filled with, the gate valve of closing after the fills with water in the connecting pipeline gets final product, so realize the requirement of a water outlet success easily.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

As shown in Figure 1, the utility model comprises diesel engine, clutch, water pump, an air compressor air intake mouth 1 is arranged on the diesel engine, suction port 1 is connected with the water outlet of water pump 5 by pipeline 2, in pipeline 2, connected gate valve 3 and float valve 4, in use the bottom valve on the intake pipe on the water pump 56 is put into water, the water outlet of sealing water pump 5, open the gate valve 3 of series connection in the pipeline 2, after starting diesel engine, air compressor is started working, and air compressor air intake mouth 1 beginning on the diesel engine is air-breathing, produces vacuum in the water pump 5 gradually, water is owing to the effect of vacuum is progressively entered in the water pump 5 by the bottom valve on the intake pipe 6, until filling with whole water pump 5, water can be because the effect of air compressor flows to pipeline 2, by observing the position of float valve 4 in pipeline, can observe the position of water in the water pump 5, when water was filled with whole water pump 5, by the clutch that closes, water pump 5 can proper functioning.

Claims

1. a diesel pump is characterized in that from water diversion apparatus: the air compressor air intake mouth (1) on the diesel engine is connected with the water outlet of water pump (5) by pipeline (2), series connection one gate valve (3) and float valve (4) in pipeline (2).
