Description
Technical field
This utility model belongs to sewage disposal system technical field, is specifically related to a kind of single pump sewage lifting pump station.
Background technology
Sewage lifting pump station is indispensable important component part in sewage disposal system, for the elevation of lifting sewage and be transported to sewage treatment plant and carry out water process.Traditional wastewater lifting device uses rustless steel or civil engineering hole body, pollutes natural environment, affects living environment, threaten personal safety, takes up room big, and civil engineering cost is high, and dredge pump and maintenance cost thereof are high.And existing container uses stainless steel welded or catch pit, and perishable, service life is short；The built-in installation of prior art pump, maintenance and repair difficulty, service life is short；Prior art tradition Floating Ball Liquid Level precision is low, and fault rate is high, the problem that service life is short；Complexity installed by existing equipment, easily blocks.
Summary of the invention
This utility model is intended at least to solve one of technical problem present in prior art.To this end, this utility model provides a kind of single pump sewage lifting pump station, it is therefore an objective to realize relatively being accurately controlled level accuracy by the change of air pressure.
To achieve these goals, the technical scheme that this utility model is taked is:
A kind of single pump sewage lifting pump station, including casing and the pump being located on casing, described casing is provided with water inlet, outlet and air vent, and described pumping plant also includes for controlling, by the air pressure change in casing, the air pressure sensing fluid level control device that water is discharged by pump from outlet.
Described air pressure sensing fluid level control device include controller and in detection case body the baroceptor of air pressure, described baroceptor and pump are all connected with controller.
Described casing also includes threaded cap and the screw thread mouth mated with threaded cap, and described threaded cap is provided with venthole, and described air pressure sensing fluid level control device is located at the outside of casing and is connected with venthole by trachea.
It is provided with the first sealing structure between described threaded cap and screw thread mouth, between trachea and venthole, is provided with the second sealing structure.
Described casing and threaded cap all use HDPE material to make.
Being connected with described outlet by water outlet joint, described pumping plant also includes the check valve being located between outlet and water outlet joint.
Described pump is detachably fixed with described casing by flange and is connected.
Described pump is that dry type installs pump.
Described pumping plant is integral type structure.
The beneficial effects of the utility model: this utility model uses air pressure sensing fluid level control device, level accuracy is high, and failure rate is low, service life is long；Use dry type that pump is installed, it is simple to maintenance and repair, lengthen pump service life；Whole Boosting pumping station is integral type structure, it is simple to transport, easy for installation；HDPE material one-shot forming water tank, no-welding-seam, macromolecular material, corrosion-resistant, lightweight, service life is long.Pump is connected by flange fixed installation on casing, it is simple to dismounting, is beneficial to safeguard.
Accompanying drawing explanation
This specification includes the following drawings, shown content respectively:
Fig. 1 is the structural representation of this utility model list pump sewage lifting pump station.
Figure is labeled as:
1, pump, 2, casing, 3, threaded cap, 4, water inlet, 5, air vent, 6, water outlet joint, 7, check valve, 8, flange.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, it is therefore an objective to help those skilled in the art that design of the present utility model, technical scheme are had more complete, accurate and deep understanding, and contribute to its enforcement.
As shown in Figure 1, this utility model is specifically related to a kind of single pump sewage lifting pump station, including casing and the pump 1 being located on casing, casing 2 is provided with water inlet 4, outlet and air vent 5, and this list pump sewage lifting pump station also includes for controlling, by the air pressure change in casing, the air pressure sensing fluid level control device that water is discharged by pump 1 from outlet.Being disposed to of air vent 5 forms confined space in avoiding casing, water is caused to come in, what certainly this air vent was preferably provided is the most smaller, make the opening and closing of air vent not affect detection and judgement that casing internal gas pressure is changed by air pressure sensing fluid level control device.Pump 1 is detachably fixed with casing 2 by flange 8 and is connected, and such as uses bolt and nut to fix connection etc., it is simple to dismounting, is beneficial to safeguard.Pump is that dry type installs pump, uses dry type to install pump, it is simple to maintenance and repair, lengthens pump service life.
Above-mentioned air pressure sensing fluid level control device include controller and in detection case body the baroceptor of air pressure, baroceptor and pump 1 be all connected with controller.Certainly, this baroceptor should use micro gas pressure sensor so that it is the sensitivity of detection reaches requirement.Specific works process is: when the water entering casing from water inlet gradually increases, the casing gas pressure collected increases, i.e. by the signal of this gas pressure in micro gas pressure sensor vasculum body, and by this pressure signal transmission to controller, processed by controller, pressure signal value and controller value set in advance is made to compare, when pressure signal value exceedes this setting value, pump startup is controlled by controller, water in casing is discharged by outlet, after water is discharged, gas volume in casing becomes big, pressure signal value changes therewith, this signal value is passed to controller by micro gas pressure sensor, control pump by controller synthesis after being processed to quit work, so circulation, enable sewage lifting pump station stable normal operation always.
It is preferred that casing also includes threaded cap 3 and the screw thread mouth mated with threaded cap, threaded cap 3 is provided with venthole, and air pressure sensing fluid level control device is located at the outside of casing and is connected with venthole by trachea.Specifically, air pressure sensing fluid level control device can be located at the outside of casing to use the form of a switch board.The setting of this structure makes air pressure sensing fluid level control device it can be avoided that contact with the water in casing and cause corrosion, and avoids baroceptor contact steam to cause job failure etc..
In order to avoid gas leakage, affect the detection accuracy of baroceptor, between threaded cap 3 and screw thread mouth, be provided with the first sealing structure, between trachea and venthole, be provided with the second sealing structure.First seals structure and can be rubber gasket, fluid sealant etc.；Second sealing structure can be fluid sealant, sealing compound etc..
Casing 2 and threaded cap 3 all use HDPE material to make.HDPE material molding water tank, no-welding-seam, macromolecular material, corrosion-resistant, lightweight, service life is long.
Being connected with outlet by water outlet joint 6, its connection can also be attached fixing by flange, and single pump sewage lifting pump station also includes the check valve 7 being located between outlet and water outlet joint.The setting of check valve makes the water discharged from outlet can only flow to the direction of water outlet joint, it is to avoid row's effluent recycling.
It is preferred that single pump sewage lifting pump station is integral type structure.The transport of pumping plant is easy in this design, and easy for installation.
Above in association with accompanying drawing, this utility model is exemplarily described.Obviously, this utility model implements and is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that method of the present utility model design is carried out with technical scheme；Or the most improved, above-mentioned design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
