Description
Technical field
The utility model relates to a kind of sealing device, is specifically related to a kind of cable sealing device of proof submersible sand discharging pump.
Background technology
The cable outlet sealing device of existing proof submersible sand discharging pump generally comprises cable outlet steel bushing, cable gum cover and cable friction top; One end of cable outlet steel bushing passes the pump housing and is connected with the pump housing; Its other end is connected with the cable friction top through bolt, is provided with the cable gum cover between cable outlet steel bushing and the cable friction top.After the immersible pump installation, cable is passed cable outlet steel bushing, cable gum cover and cable friction top successively, adjust that swivel bolt compresses behind the position, fixing.
The weak point of this submersible pump cable outlet sealing device is:
1, the installation of submersible pump cable, dismounting and maintenance are very inconvenient, and for guaranteeing the better seal effect, the space between the internal diameter of the outside diameter of cable and steel cable outlet steel bushing and cable friction top is less; And the outside diameter of cable is because rubber finished product outside dimension is wayward; Often the outlet outside diameter of cable makes that more greatly perforation is difficult, the cable surface wear problems, when the outside diameter of cable is excessive, can't pass sealing device especially; And when pump maintenance maintains; Must cable all be pulled out in cable outlet steel bushing and cable friction top, operation is very inconvenient, and it is time-consuming to require great effort.
2, sealing effectiveness is bad, and is less because of cable joint-box and seal rubber sleeve contact area, can't reach desirable sealing effectiveness, the seepage phenomenon can occur.
The utility model content
The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of cable sealing device of proof submersible sand discharging pump is provided, and good airproof performance and convenient disassembly can reduce the wearing and tearing of cable, reduces the maintenance cost of cable.
The utility model is the deficiency that solves the problems of the technologies described above; The technical scheme that is adopted is: a kind of cable sealing device of proof submersible sand discharging pump; Comprise cylindrical shell, flange plate, cable sealing box, rubber seal piece and fastening bolt; The edge of said flange plate is provided with opening, and the bottom of cable sealing box and a sidewall are provided with opening, and the bottom opening of cable sealing box be located in the opening part of flange plate downwards; And the sidewall opening of cable sealing box is provided with outwardly; Be welded to connect between cable sealing box and the flange plate, the rubber seal piece is arranged in the cable sealing box, leaves the space between the rubber seal piece sidewall relative with the cable sealing box sidewall opening; Said rubber seal piece is made up of sealing block on the rubber that cooperatively interacts and rubber lower seal piece; Be respectively equipped with groove on the face that sealing block and rubber lower seal piece fit on the rubber, the groove amalgamation forms a plurality of cable passages, and said rubber lower seal piece is provided with the slope shape rubber blanket in the extension of the two ends of cable passage axis direction; The extreme higher position of slope shape rubber blanket is lower than the position of cable passage, and it is fastening with it that said fastening bolt passes the top board of circumferential flange, rubber seal piece and cable sealing box of cylindrical shell successively.
The beneficial effect of the utility model is: good airproof performance, convenient disassembly; Can change different rubber seal pieces according to the cable of different model, versatility is good, and at cable extending port place the slope shape rubber blanket is set; Can effectively reduce the wearing and tearing between cable and the cylindrical shell, reduce the maintenance cost of cable.
