Description
This belongs to the centrifugal pump class from the vertical sewage pump of double suction.
The sewage pump that prior art provided has two classes: a class is a submerged pump, pump and group of motors slip into sewage, it is easy to wear, working life is short, cost is high, need multiple supervision be set to mechanical seal, cable, lowest water level etc., complex structure also has a kind of Under Water Pumps, and pump is placed sewage, motor is placed on ground, pump is connected with major axis with motor shaft, and the dirty degree of depth of diving is subjected to the restriction of pump shaft, and efficient is low; Another kind of is horizontal pump, pump is connected with the motor shaft level, all place on the support on ground, the suction sleeve of this pump need have bottom valve, and bottom valve resistance, energy loss are arranged, need water before the operation, meet solid matter and block bottom valve, irritate discontented diversion, or produce water leakage phenomenon, pump can not normally be moved, deficiency such as floor space is big.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provide a kind of without bottom valve, efficient height, long service life, floor space little, use easy to maintenance from the vertical sewage pump of double suction.
This is implemented with following technical proposals from the vertical sewage pump of double suction, with water ring vaccum pump and centrifugal pump technological synthesis new technology together, promptly by being equipped with in the scroll casing shape pump housing 13 chambeies, the double shrouded wheel 15 of following suction port, on it, on following seam connects, following suction casing 18,12 constitute sewage pump, dress vacuum pump impeller 10 seams connect vacuum pump body 8 formation vacuum pumps in the circular port below the following suction casing 12, seam connects pump seat 4 again, last suction casing 18 top and link press spans 22, motor cabinet 25 seams connect, adorn motor 28 topmost, establish bearing box 23 buried bearings 24 above the link press span 22, establish water middle (center) bearing 6 in pump seat 4 circular holes and form, main feature is that impeller 15 and vacuum pump impeller 10 are connected on same the pump shaft 16.
Below in conjunction with accompanying drawing 1, the utility model is described further from the vertical sewage pump structural representation of double suction.From the vertical sewage pump structure of double suction as shown in Figure 1, it is equipped with at the middle part of pump shaft 16 key 14, the double shrouded wheel 15 of following suction port, the scroll casing shape pump housing 13 is arranged outward, on the pump housing, on following seam connects, following suction casing 18,12, strong 9 dress water ring vacuum pump vanes 10 in the round chamber below the following suction casing, and seam connects water ring vaccum pump body 8 seam connection pump seat 4 again, edge water centre bearer bush 3 in the pump seat hole, key 7 dress water middle (center) bearings 6, the anti-sandpipe 5 of oblique cutting in the annular chamber, bolt links water middle (center) bearing lid 1 in the circular hole of bottom surface, there is lengthening plug screw 2 its bottom surface, dress sealing 20 in the top circular hole of last suction casing 18, with sealing gland 21, bolt is pushed down, and seam connects link press span 22, bearing box 23 is housed in the circular hole above it, in bearing 24 is arranged, with bearing cap 26 bolton, pump shaft 16, the location is supported with bearing 24 in the upper end, the lower end is inserted in the water middle (center) bearing 6 and is covered with nose circle, screw, spline locks solid, pump shaft all has segmentation protective shaft sleeve 17 outward, connects motor cabinet 25 and motor 28 with seam above the link press span, and pump shaft head and motor shaft connect with coupling 27.The pump housing 13 upper and lower suction casing 18,12 vacuum pump body 8, pump seat 4, and link press span 22 stop portion each other all has low pad sealing, use bolton, last suction casing 18 is connected with pipeline with the suction chamber of vacuum pump body 8 and is constituted vacuum gas handling system 11, the pipeline of the discharge side of vacuum pump body 8 after with the water outlet flashboard valve plate of the logical pump housing 13 water outlets of pipeline, sealing 20 and bearing 24 places are equipped with grease cup 19 and form.
This is from the installation and operation of the vertical sewage pump of double suction: this pump is equipped with two kinds of situations: 1. directly be installed on the concrete foundation with stone bolt; 2. pump is installed on the flooring, and as the ships deck, the vibrations that damping device is avoided flooring or deck can be installed in building ground under pump seat, and vibration damper can be Rubber shock-absorbing pad, spring shock absorption pad, other type beam.This water pump suction pipe has three kinds of installation forms: 1. two suction sleeves directly feed pond (or cesspool), and according to field condition suction sleeve angle rotatable, two suction sleeves can be same direction, or are mutually 90 ° or 180 ° and can install 30 °, 60 ° positions; 2. two suction pipes feed the pond with the synthetic pipe of F shape; 3. two suction pipes feed the pond with the synthetic pipe of Y shape.Need fill the water in the vacuum pump when moving for the first time, operation later on then shouldn't.Could primer pump when going out Water gate valve and closing, borrow atmospheric action after taking out most suction inner air tube, liquid is transported to double-entry impeller along suction sleeve.Can be converted to the pressure energy of liquid to liquid machine through impeller centrifugal force, open out Water gate valve, liquid is exported along discharge tube.The water ring vacuum pump vane flow is in parallel with the centrifugal pump impeller flow and be transported in the pipeline behind the water outlet flashboard valve plate.Regularly turn round down and add the assorted dirt of stay bolt discharging.
This is from the advantage of the vertical sewage pump of double suction: compact structure, can self-priming, without water, do not have and leak, suck symmetry, axial force is little, operates steadily, and bearing, filler life-span are long, without bottom valve saves the bottom valve drag losses, thoroughly avoid solid matter to block bottom valve and irritate discontented diversion, leak the diversion phenomenon, floor space is little, pump efficiency is high, and is reliable.This series pump meets international standard IS02858, IS03555 requirement and inherits twentieth century China IS, series such as SH, S, holds these serial performance parameters down, and generalization has inheritance.Can replace submerged pump when vertical setting height(from bottom) is less than 5 meters, sewage pump, slurry pump adopt Y type motor; Energy self-priming, nothing are leaked and can be replaced a lot of oil pumps, chemical pump, Under Water Pumps; As series pump such as IS, DL, SH, S; Can carry solid, liquid, gas three-phase mixed solution to use in screw pump, reciprocating pump occasion, not have bottom valve and spring, passing capacity is better than screw pump and reciprocating pump.
This can carry clear water, sewage, rainwater, mud, oils from the vertical sewage pump of double suction, allows to carry to contain solid to a certain degree, the solid, liquid, gas three-phase mixed solution of gas, extensively is adapted to t≤60 ℃, the agricultural drainage and irrigation between the ph4--10; Municipal sewage treatment; Moisture, sand grains foreign material, rock gas, petroleum crude oil and similar oils, tall building, colliery, power plant, chemical plant, ships hold; Places such as chemical industry, food, medical treatment, commerce.
