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 double pump sewage lifting pump station, including casing 3 and two pumps being located on casing, casing 3 is provided with water inlet, outlet and air vent 6, and double pump sewage lifting pump station is also included for alternately being controlled the air pressure sensing fluid level control device that water is discharged by two pumps from outlet by the air pressure change in casing.Being disposed to of air vent 6 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.
Preferably, two pumps are respectively the first pump 1 and the second pump 10, water inlet includes the first water inlet 5 and the second water inlet 7, outlet includes the first outlet and the second outlet, and air pressure sensing fluid level control device alternately controls the first pump and the second pump and discharges the most corresponding for water from the first outlet and the second outlet.First pump 1 and the second pump 10 are all detachably fixed with casing 3 by flange 12 and are connected, and such as use bolt and nut to fix connection etc., it is simple to dismounting, are beneficial to safeguard.First pump 1 and the second pump 10 are dry type and install pump, use dry type to install pump, it is simple to maintenance and repair, lengthen pump service life.First pump and the second pump are equipped with hanger 2 away from the one end being connected with casing.Air pressure sensing fluid level control device include controller and in detection case body the baroceptor of air pressure, baroceptor, the first pump 1 and the second pump 10 are all connected with controller.Certainly, this baroceptor should use micro gas pressure sensor so that it is the sensitivity of detection reaches requirement.nullSpecific works process is: when the water entered in casing from the first 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，Controlled the first pump 1 by controller to start，Water in casing is discharged by the first 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 the first pump by controller synthesis after being processed to quit work，Now close the first water inlet，By the second water inlet water inlet，With above-mentioned same operation principle，Controller controls the work of the second pump by the pressure signal in micro gas pressure sensor vasculum body，The second pump is made to be discharged by the second outlet by water，So alternate cycles，Enable the stable normal operation always of double pump sewage lifting pump station.Using double pump technology, two pumps are used alternatingly, and make pump have abundant time of having a rest, failure rate is low, and service life is long.
Casing also includes threaded cap 4 and the screw thread mouth mated with threaded cap 4, and threaded cap 4 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.Overhauling for convenience, casing can also include overhauling installing hole and for covering the lid of maintenance installing hole, this lid with overhaul the structure that installing hole can also be arranged like threaded cap and screw thread mouth matching thread is connected.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, be provided with the first sealing structure between the first threaded cap 4 and the first screw thread mouth, between trachea and venthole, be provided with the second sealing structure.First sealing structure can be rubber gasket, fluid sealant etc..Second sealing structure can be fluid sealant, sealing compound etc..
Casing 3 and threaded cap 4 all use HDPE material to make.HDPE material molding water tank, no-welding-seam, macromolecular material, corrosion-resistant, lightweight, service life is long.
Double pump sewage lifting pump station also includes the U-shaped threeway 9 being connected with the first outlet and the second outlet.The design of this structure is easy to discharge discharge water from an outlet.
It is connected by the water side of water outlet joint 8 with U-shaped threeway 9, between U-shaped threeway 9 and the first outlet and the second outlet, is equipped with check valve 11.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 double 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.
