The weak point of this cable fixed form is: at first, in the course of work behind pump startup, because flowing of water, can produce irregular disturbance to the combination of cable and steel wire rope, long-time running is gone down, may cause the insulating barrier wearing and tearing of cable, and cable occur and leak, cause the damage of motor.In addition, because control cable is thinner, this phenomenon is more much bigger than power cable to the harm of control cable, might cause control cable to be broken, and influences the transmission of control and protection signal, causes the inefficacy of protection and warning function.Secondly, the fixing final step operation of cable is to tighten up the tackle open auger to buckle in this cable fixed form, this mode of operation is higher to operator's specification requirement, if tackle open auger deduct is got too tight, in fact is equivalent to pump has been applied a pulling force that makes progress.This situation appears, pump when normal operation, be do not have dysgenic; but when emergency shutdown, since flow backwards, the impeller counter-rotating; form hydraulic turbine operating mode, water pump body will be subjected to a thrust that makes progress, and adds pull of steel wire; if making a concerted effort of these two power greater than the deadweight of pump; will make pump produce drift (lifting the machine phenomenon) upwards, break away from anti-reverse mechanism, when serious; can twist the outage cable even, and this obviously to be us do not wish to see.Once more, submersible axial flow pump for low lift, pumping plant adopts the quick flow-breaking device usually, after cutting off the electricity supply, may occur that: in outlet passage, because current flow backwards, make outlet passage top produce the parital vacuum state, and the glassware for drinking water of bottom have 1 atmospheric absolute pressure in the runner, there is pressure reduction the runner upper and lower, the pressure height of bottom; Thereby produce thrust upwards, also can make pump produce drift upwards.This situation obviously also need be avoided.
Summary of the invention
Purpose of the present invention is exactly will solve the deficiency of above-mentioned cable fixed form and the cable of a kind of immersible pump of proposing is fixed and guard method, and this method can limit the drift of immersible pump.
For achieving the above object; the cable that the present invention proposes a kind of immersible pump is fixed and guard method; this method is the cable outer setting sleeve pipe at immersible pump; sleeve pipe top is connected with the pit shaft lid by sleeve pipe stopping means and bobbin seal device; sleeve pipe bottom and motor for submerged pump are tightly connected; fix and protect the cable of immersible pump, limit the drift of immersible pump simultaneously.
Usually described sleeve pipe stopping means comprises tube connector, the depression bar that is connected with sleeve pipe, be fixedly connected on the fixed head that welds with the pit shaft lid by bearing pin and split pin, the axial force transmission that makes progress that will cause the immersible pump drift is to the basis, limiting boot moves up, to avoid upwards drift of water pump.
Described bobbin seal device adopts stuffing box structure, and by bolt, nut gland, pressing plate, stuffing box, filler that sleeve pipe is outer and be welded on stuffing box base plate fixed seal connection on the fixed head, gland is made the subdivision structure, is convenient to install.
Sleeve pipe of the present invention bottom is tightly connected by protective cover and motor for submerged pump terminal box.
Usually of the present invention being tightly connected all adopted O " type circle sealing, also can adopt other encapsulating method well known to those skilled in the art simultaneously.
The present invention constitutes a cavity that separates with current by said structure, and cable passes through in this cavity, and no matter how rapid the current outside are, as long as sealing place does not produce leakage, current can not exert an influence to cable, and cable can not rock, and have fundamentally stopped the wearing and tearing of cable.Simultaneously because structure of the present invention has also limited the drift of immersible pump.
The present invention compared with prior art, novel structure, easy to use, cable does not contact with water in rigid casing, can not produce because of the impact of current and rock, and has fundamentally solved the cable wear problems, can also play simultaneously the effect of restriction electric pump drift.
