SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the not enough of above-mentioned current device, provide a immersible pump stainless steel arm-tie fixed knot for well and construct, through the water inlet festival and the play water festival that the deep-well pump was connected to the arm-tie, improve the structural strength of deep-well pump, stability is strong and the installation is simple.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a immersible pump stainless steel arm-tie fixed knot constructs for well, is located between the water inlet section and the play water festival of multistage deep-well pump, including certain quantity circumference evenly distributed's arm-tie, arm-tie lower extreme inboard is fixed with the screw rod, is equipped with corresponding screw rod hole on the water inlet section, is equipped with the outer sleeve outside the play water festival, and the outer sleeve main part has certain clearance with a water festival, and establish to throat and play water festival offset the upper end, be equipped with on the outer sleeve with arm-tie quantity assorted opening, the arm-tie is equipped with the section of turning over on of inside buckling for the opening part position. The screw rod and the pulling plate can be fixed by welding, the thread section of the screw rod penetrates through the screw rod hole, the nut is screwed on to fix the lower end of the pulling plate, and the upper turning section at the upper end of the pulling plate is inserted into the opening to be limited and is of a bolt type structure.
Preferably, a notch is arranged at the contact position of the upper end of the water inlet joint and the pulling plate, and a lower bending section bent inwards is arranged at the position, corresponding to the notch, of the pulling plate. The notch is plane shape, and the design of lower inflection section lets the arm-tie inwards retract, avoids producing with the screen panel outside the water inlet festival and interferes.
Preferably, a flat limiting block is fixed on the inner wall of the pulling plate below the upper turning section, and the limiting block is positioned in the opening of the outer sleeve. The pull plate and the limiting block can be fixed through welding, the outline of the opening is larger than that of the limiting block, the bottom surface of the limiting block abuts against the lower inner wall of the opening after installation, and the pull plate is high in stability and pressure resistance and not prone to falling off.
Preferably, the pulling plate and the limiting block have certain radians and are matched with the profile of the deep-well pump cylinder.
Preferably, the number of the pulling plates is four, and the pulling plates are positioned at the quartering positions of the deep well pump cylinder.
The beneficial effects of the utility model reside in that: 1. the water inlet joint and the water outlet joint of the deep well pump are connected through the pulling plate, so that the structural strength of the deep well pump is improved, and the pump barrel is prevented from being broken under the condition of high pressure;
2. the lower extreme of arm-tie is threaded connection, and the upper end is the bolt formula connection, and the inside compression volume of volute has been guaranteed in the design of bolt connection structure, prevents the inside rotation of volute, and structural stability is strong, and the installation and dismantle are simple, and follow-up maintenance is more convenient, prolongs its life.
