Description
Technical field
The utility model belongs to water pump hydraulic technical field, it particularly relates to be that water pump is anti-reverse and anti-lift
Machine device.
Background technology
Water pump in the process of running, because pumped (conveying) medium is flowing in pit shaft, can be produced to the cable in pit shaft and do not advised
The disturbance of rule, such as cable are without reliably fixed and protection, then the sealing of cable and insulating properties will be destroyed, to motor
Safe operation brings very big potential safety hazard.
If the 1, cable is fixed in pit shaft with steel wire rope and geometrical clamp, too small to the tightening force of steel wire rope, the guarantor of cable
Shield effect is not obvious;Tightening force is excessive, a upward pulling force will be produced to water pump, alleviates pump weight, also reduce water pump bottom
The frictional resistance moment of seat and seat ring, once water pump vane is inverted, easily occurs the phenomenon for twisting power-off cable.
2nd, when water pump stops, the pumped (conveying) medium in pipeline will be flowed back due to deadweight, and impeller is by withdrawing fluid
Effect, there is impeller reversion, form hydraulic turbine condition, water pump body by by one upward thrust of liquid in runner, plus
The pulling force effect of upper steel wire rope, if water pump deadweight is less than making a concerted effort for two upward power, water pump will produce upward drift
Simultaneously, reversal development can also occur for lift machine phenomenon.
3rd, water pump is in normal operation, and the pumped (conveying) medium such as powered off suddenly etc. in phenomenon, outlet passage flows back, in runner
End produce parital vacuum phenomenon, and in the front end of open type runner, because the effect of atmospheric pressure forms pressure differential so that
Water pump one upward thrust of formation, so as to while lift machine phenomenon is produced, also generate reversal development.
The content of the invention
The technical problems to be solved in the utility model is to provide that a kind of water pump is anti-reverse and lifting-proof machine device, can effectively prevent
Water pump inverts the device with lifting-proof machine.
In order to solve the above technical problems, the technical solution adopted in the utility model is:Water pump is anti-reverse and lifting-proof machine device,
Including water pump, cylinder and cable, described cable one end connects water pump, and the other end connects the power supply of peripheral hardware, and the cylinder is socketed in
On the outside of water pump, protective cover body is additionally provided with, the cable is arranged in rigid protective cover body, and the exit of cable passes through electricity
Cable geometrical clamp is fixed on the top of body, and the exit is the one end for the power supply for connecting peripheral hardware.To prevent cable in conveying liquid
Rocking in body medium, in the utility model need to whole cable to be protected be installed in rigid protective cover body, prevent
Working fluid impacts cable;Body top is fixed in the middle of body with fastening clip for cable by end cable is drawn, and prevents cable and pipe
Wall friction.
As an improvement, the pump housing of the water pump is provided with a pair of torsional stops with anti-rotation groove, the cylinder inboard wall of the water pump
A pair of anti-rotation channel-section steels of upper setting;Anti-rotation channel-section steel corresponds with anti-rotation groove card and sets and be connected by way of clamping.For
The destruction for preventing water pump reversion from being caused to equipment, increases on a pair of torsional stops with anti-rotation groove, torsional stop on pump body
Anti-rotation groove is stuck on the anti-rotation channel-section steel being fixed on cylinder inboard wall, so as to effectively prevent the generation of water pump Reversion, thus is protected
Having demonstrate,proved cable will not be destroyed because of reversion.
As an improvement, being additionally provided with taper protective cover, taper protective cover is located between water pump outlet box and protective cover body, institute
The lower end for stating taper protective cover is pressed in the top of water pump outlet box;The protective cover body upper end is additionally provided with compressing member, compressing member
Including holddown plate and stretching screw, holddown plate is overlayed at the top of protective cover body, and stretching screw number is more than a pair,
The even surrounding for being distributed in holddown plate, one end connection holddown plate of stretching screw, the other end connects the upper end of the pump housing.So set
Meter, can effectively prevent water pump from lifting machine,
As an improvement, being additionally provided with cushion pad between the holddown plate and protective cover body.The setting of cushion pad can be effective
Absorbing, it is to avoid influence of the rigid support to water pump axial force balance.
The beneficial effects of the utility model are:1st, simple and practical, reliably protecting cable is not impacted by working fluid,
Nothing is substantially rocked in rigid casing, it is to avoid the friction destruction of cable and rigid casing;2nd, anti-reverse-rotation structure is reliable, is prevented effectively from
The influence that water pump reversion is run to equipment;3rd, lifting-proof machine structure is novel reliable, effectively prevent in water pump operation and shut down
Influence of the machine phenomenon to equipment safety stable operation is lifted in journey.
