Summary of the invention
It is long that the purpose of the utility model is to solve existing pollution discharge pump coupling shaft; Very easily cause the axle bush wearing and tearing, cause the swing of impeller coupling shaft bigger, impeller directly contacts with impurity; The problem of blocking pipe very easily provides a kind of stable, pipeline not allow susceptible to plugging vacuum inverse inhalation type drainage.
For realizing above purpose, the technological scheme of the utility model is a kind of vacuum inverse inhalation type drainage, comprises motor and water pump; Motor is connected with water pump through coupling, and the import of water pump is connected with intake pipe, and the outlet of water pump is connected with outlet pipe; The intake pipe of described water pump is connected with water storage box; Described water storage box is connected with suction sleeve, and described suction sleeve one end is fixedly connected with water storage box, and the described suction sleeve the other end is connected with safety check.Before operation, earlier with filling in the water storage box, starting electrical machinery then; Motor rotates and drives the water pump rotation, and water pump absorbs water from water storage box, makes the negative pressure space that forms a similar vacuum in the water storage box; When negative pressure in the water storage box during greater than the pressure of sewage in the suction sleeve pipe; Sewage is inhaled into from suction sleeve in the underground sewage reservoir, gets rid of from horizontal circulating-pump outlet, accomplishes the purpose of whole blowdown; Removed the impeller coupling shaft, solved the problem that causes the pump housing to run well because of coupling shaft wearing and tearing axle bush, changed pollution discharge pump impeller and the mode that impurity directly contacts, solved pipeline and be prone to blockage problem.
As preferably, described motor is connected with floating-ball fluid level transmitter, and described floating-ball fluid level transmitter is arranged in the water.Floating-ball fluid level transmitter is controlled pollution discharge pump automatically and is opened and closed, and accumulates arrival certain altitude pollution discharge pump when liquid level and opens automatically, drains into certain low liquid level pollution discharge pump and closes automatically, need not special messenger's operation.
As preferably, described water storage box top also is provided with filler pipe, and described filler pipe and water storage box welding are fixing, are connected with valve on the described filler pipe.The filler pipe at water storage box top makes things convenient for the water of adding loss for water storage box, can also be used to getting rid of the gas in the water storage box, and the valve on the filler pipe seals.
As preferably, the intake pipe of described water pump and outlet pipe are equipped with one section rubber hose.The intake pipe of water pump and outlet pipe all are connected with rubber hose, in the water pump operation process, reduce the vibrations that pump operation causes.
As preferably, also be provided with butterfly valve on the intake pipe of described water pump and the outlet pipe.Also be connected with butterfly valve on the intake pipe of water pump and the outlet pipe, butterfly valve both can have been regulated the flow in the pipeline, can when the maintenance water pump, close butterfly valve again, played buffer action.
As preferably, described water pump is horizontal recycle pump.Horizontal recycle pump is water-tight, and magnetic drives does not have dynamic seal, has fundamentally eliminated seepy question; Noise is little, and the precision of vital part reaches 2/1000ths millimeters, guarantees quiet performance; Life-span is long, adopts mirror face ceramics and ceramic nano bearing to resistance to wear, and guarantees the long lifetime.
The utlity model has following beneficial effect: thoroughly changed the discharge opeing principle of pollution discharge pump, removed its complex component, guaranteed the steady running of pollution discharge pump, practiced thrift the buying and the maintenance cost of parts; Change pollution discharge pump impeller and the mode that impurity directly contacts, solved pipeline and be prone to blockage problem, practice thrift cost of equipment maintenance, reduced personnel's activity duration.
