Description
Technical field
The utility model relates to sand winning machine tool field, particularly relate to a kind of when sand pump initialization the device for diversion.
Background technique
The pipeline of sand pump is substantially all adopt Large Diameter Pipeline large discharge, is generally unsuitable for installing bottom valve, damages because bottom valve can increase the pipe taking out sand tube road on the one hand, and be that the sand in water is comparatively large to its wearing and tearing on the other hand, water sealing effect is difficult to ensure, working life is of short duration.Because the feed-water end of sand pump is not provided with the non-return devices such as bottom valve, when sand pump is shut down, aqueous reflux in pipeline and be in emptying state, and when next time, start ran, it enters aspiration phases diversion must to be provided just can to guarantee to it.Normally install the negative pressure device such as Nash hytor or jet pump unit at the water outlet side of sand pump at present, make to become in sand pump negative pressure state in the diversion stage, thus reach diversion object.But, adopt Nash hytor or jet pump unit when the diversion stage provides negative pressure for sand pump, need ensure that the waterexit end of sand pump is in closed cut-off state, the valve preventing from leaking gas must be installed additional at water outlet, and sand pump at work, silt is equally comparatively serious to the wearing and tearing of this valve, makes its working life shorter, and leakage efficiency is difficult to maintain.
Model utility content
For overcoming above-mentioned technical problem, the utility model provides one in conjunction with design science, Appropriate application is taken out large junk and is carried high-pressure flush pump and sand pump self-characteristic, ingeniously realizes sand pump diversion, and without the need to installing the sand pump water diversion apparatus of valving at the feed-water end of sand pump and waterexit end.
For realizing above-mentioned technical purpose, the utility model adopts following technical proposals: a kind of sand pump water diversion apparatus, and it comprises high-pressure flush pump, sand pump, and high-pressure flush pump is connected with inlet pipeline and flushing pipe, inlet pipeline end is provided with bottom valve, and sand pump is connected with inhales sand tube road and sand discharge pipeline; The waterexit end of high-pressure flush pump separately communicates with a diversion pipeline; Diversion line end is connected with sand pump sand discharge end through a water pipe, and the line end of diversion is simultaneously connected with the feed-water end of water jet pump again; The suction end of water jet pump then communicates with the sand-absorbing end of sand pump through a negative pressure line; Flushing pipe is provided with bath gate valve, and diversion pipeline is provided with diversion switch valve, and water pipe is provided with the one-way valve only allowing water to flow to sand pump, and negative pressure line is provided with Vacuum ball valve.
Described diversion pipeline is communicated with the waterexit end of high-pressure flush pump through flushing pipe, and the tie point of itself and flushing pipe is positioned on front side of gate valve of washing by water.
Described water pipe is connected with the sand discharge end of sand pump through sand discharge pipeline, and the tie point of itself and sand discharge pipeline is higher than the sand discharge end of sand pump.
Described negative pressure line is connected with the sand-absorbing end of sand pump through inhaling sand tube road, and it is positioned at the tie point inhaling sand tube road and inhales upper end portion, sand tube road.
Working principle of the present utility model is, when taking out the non-operation of large junk, high-pressure flush pump, sand pump are in outage state, and high-pressure flush pump is provided with bottom valve due to inlet pipeline end, has diversion in its pipeline, and the pipeline of sand pump is then emptying state, during operation, gate valve of washing by water is closed, diversion switch valve is opened, Vacuum ball valve is opened, start high-pressure flush pump and sand pump, the water that high-pressure flush pump exports enters in sand pump as diversion through water pipe on the one hand, on the other hand then for water jet pump provides working flow, water jet pump draws the air in sand tube road through negative pressure line, because the diversion of sand pump its upper end under operating condition can not to sand-absorbing end reflux, and then play the effect of water seal, along with the air inhaled in sand tube road reduces, its internal liquid level rises gradually, in time rising near sand pump sand-absorbing end, sand pump can enter normal pump water state, subsequently Water gate valve is opened, diversion switch valve cuts out, Vacuum ball valve is closed, take out large junk and get final product manufacturing operation.
The utility model has following beneficial effect: it reasonably make use of takes out the self-characteristic that large junk carries high-pressure flush pump and sand pump, ingeniously realize sand pump diversion, and without the need to adding sealed valve on the sand discharge pipeline of sand pump, more bottom valve be need not install on suction sand tube road, the stability of sand pump work and the leakproofness of pipeline ensure that.Abandon wear part due to it simultaneously, avoided unnecessary cost and drop into, decrease plant maintenance, part exchanging etc. and operate the impact that manufacturing efficiency is brought.
