Abstract
The utility model discloses an intermediate station pumping system device of a long-distance pipeline coal transporting system. The intermediate station pumping system device consists of a coal slurry inlet, outlet main pipelines, one pressure transmitter, the other pressure transmitter, a valve and a main pump machine set. The inlet end of coal water slurry inlet main pipeline is connected with one pressure transmitter, the outlet end of the coal slurry outlet main pipeline is connected with the other pressure transmitter, the coal slurry inlet main pipeline and the coal slurry outlet main pipeline are sequentially and respectively in parallel connection with main pumps in head-to-end mode, and any one of the six main pumps serves as a standby pump. The intermediate station pumping system device is reasonable in structure, convenient to use, safe and reliable, ensures safe operation of pipelines, improves the pump station utilization efficiency and prolongs the service life of pump stations. When the intermediate station pumping system device runs normally, the six pumps undertake flows of five pumps, running load of each pump is reduced, and the service life of the pumps are prolonged. When the main pumps are required to be overhauled, the flows of the overhauled pump are reduced, and the flows of other pumps are increased. When the overhauled pump shuts down, other five pumps undertake transportation flows of the six pumps.
Description
Technical field
The utility model relates to COAL SLURRY PIPE TRANSPORT, is specifically related to the midship pumping system device of long-distance pipe coal handling system.
Background technique
China's solid material is from the place of production to user at present, and its product is preferably used railway basically, and highway is selected water transport in place with good conditionsi, and all there is certain defective in above-mentioned three kinds of means of transportation:
1), railway transport: because railway transport is subjected to the restriction of train number scheduling and transport capacity, can not in time the Coal Transport of Product transport to client place, especially thermal power plant often can not be satisfied the demands.
2), highway transport: because highway transport vehicle is too much, be prone to accident in the road, block up, harsh weather etc. have had a strong impact on conveying efficiency.
3), water route transportation: owing to being subjected to the impact of geographical environment, need to repeatedly have bad luck, increase haulage time, coal loss and the environmental pollution in the way.
4), above-mentioned several means of transportation also exist along with the price of the energy promotes, cost of transportation also will improve gradually.Simultaneously, a large amount of dischargings of vapour, diesel exhaust have destroyed environment in transportation process, and the loss of airborne dust and material is also larger in the way.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, and is easy to use, the midship pumping system device of safe and reliable long-distance pipe coal handling system.
In order to guarantee the safe operation of pipeline; reduce the pipeline outage rate; the technical solution of the utility model settling mode is: this device of midship pumping system device of a kind of long-distance pipe coal handling system is by coal slurry entrance main pipe; coal slurry outlet main pipe; one pressure transmitter; another pressure transmitter; valve; the main pump unit forms; special way of the present utility model is that the entry end of described coal slurry entrance main pipe connects a pressure transmitter; the outlet end of described coal slurry outlet main pipe connects another pressure transmitter; described coal slurry entrance main pipe; the first main pump successively is connected in parallel from beginning to end respectively between the coal slurry outlet main pipe; the second main pump; the 3rd main pump; the 4th main pump; the 5th main pump; the 6th main pump wherein selects arbitrarily 1 main pump as stand by pump in 6 main pumps.
Described main pump system head and the tail two ends all arrange pressure transmitter, the operation of the pressure control main pump by pressure transmitter.
Described each main pump inlet pipeline and outlet conduit all are connected with valve, and each pump inlet valve specification is identical, and each pump discharge valve specification is identical.
The utility model compared with prior art has rational in infrastructure, easy to use, safe and reliable characteristics, in order to guarantee the safe operation of pipeline, improve the utilization ratio of pumping plant, increase the working life of pump, when simple mode is taked the main pump normal operation exactly, each pump is in running state, when a certain main pump of operation need to overhaul, increases other its main pump flows, reduce the maintenance pump duty, main pump stops the most at last.Like this, the pump group is in running, and every pump is all being born operating flux, greatly reduces the operating load of every pump.And can adjust according to main pump inlet/outlet pressure condition the running state of main pump.
Description of drawings
Fig. 1 is many pumps of the utility model switching construction schematic diagram.
Embodiment
Accompanying drawing is embodiment of the present utility model.
