Description
Technical field
The present invention relates to immersible pump field, specifically a kind of solar energy well immersible pump.
Background technique
Agricultural irrigation is often to obtain from well with water or the life water of remote districts, needs to use well water pump, water
Pump setting on the ground, needs when pump startup to pour water, trouble is shown slightly, so generally immersible pump form.
Existing well water pump is to use conventional general immersible pump, and much need remote power transmission under use environment,
Laying-out trouble, and the installation of immersible pump is inconvenient, if direct steel cable hanging is gone down, shakes in the process of running aobvious
It writes, trouble is then installed if the components such as shaft bottom setting mounting base, and mounting height can not be adjusted.
Immersible pump passes through some liquid in use, the motor as caused by water level decreasing, motor are exposed burns out and also happens occasionally
Bit switch etc. is also required to the complicated control cabinet of setting if determining working water level, warning line.
Well water, which is conveyed toward farther place, needs higher lift, by the regulative mode adjustable range for changing motor speed
It is smaller, it is applicable in scene and is also just restricted.
Summary of the invention
The purpose of the present invention is to provide a kind of solar energy well immersible pumps, to solve the problems of the prior art.
To achieve the above object, the invention provides the following technical scheme:
A kind of solar energy well immersible pump, including pump head, motor and outlet pipe, motor are mounted on pump head one end driving pump head
Acting, outlet pipe connect at pump head and extraneous water, and immersible pump further includes solar panels, and solar panels are arranged on the ground, too
Positive energy plate is connected to motor by cable；Pump head top is fixed with leading truck, and immersible pump further includes guide post component, guide post group
Side wall is arranged in well in part, and leading truck is along guide post component vertical sliding.
Solar panels are motor power supply, so that the well water under many agricultural scenes irrigates the puzzlement for getting rid of remote power transmission,
Pump head is installed in the well by guide post component, has both prevented the shaking of its operational process, can also facilitate the external world along guide post group
Part is mounted and taken out pump head, also facilitates operation when needing to change pump head mounting height.Solar panels should be in local sun maximum
The sun is directed at so as to energy efficiency power generation.
Further, immersible pump is inverted in well: pump head is in upper, motor under.Such set-up mode can adequately protect
Motor, because being immersible pump, motor is submersible motor, without the fan of air-cooled motor, cannot directly be used in air,
The present invention in use, during water pumping water level decreasing, arrive first at pump head, continue pump well water, water level decreasing, water inlet
Anhydrous entrance, water level stop decline, and motor is still in water, so can be fully cooled by surrounding water, if electric at this time
Machine is upper, then motor can be burnt out quickly when below water level decreasing to motor.
Further, pump head includes the pump housing, impeller, pump shaft and a cap assemblies, an effluent seat for several identical quantity；
Impeller is set on pump shaft and is sequentially connected with pump shaft, and impeller and pump shaft are respectively positioned in the pump housing, pump shaft axis and pump
Body center line is overlapped, and pump shaft includes square toes and positioning section, and square toes and positioning section are located at the both ends of pump shaft, the positioning section axis of centres
Square inner bore is externally provided with to court；The pump housing, impeller, pump shaft are sequentially overlapped in the axial direction, are locked between the pump housing by fastener,
Gasket or sealing ring are set on the contact surface between the pump housing, grafting is carried out between pump shaft and pump shaft, square toes are inserted into square inner bore,
The shaft shoulder of the end face of positioning section against another pump shaft in square toes end carries out axially position；Square toes and square inner bore undertake axis
Torque transmitting between axis, the power exported at motor from below are successively up transferred to each pump shaft, and pump shaft is again with movable vane
Wheel rotation, to pump water body, since the torque of every level-one pump shaft is different, the pump shaft torsion moment of bottom is maximum, the top
Torque is minimum, thus in structure design can slightly overstriking bottom end pump shaft, or to be on the safe side, all pump shafts all manufacture
Ground is more slightly so that there are more safe clearance, by water level-one grade pressurization pumps impeller downwards, when needing the lift of increasing pump,
It is increased by the series of pump, the present invention uses modularized design, and the pump housing, impeller, pump shaft at grade, can individually add up in layers,
As long as pumping, intensity is enough, and power of motor is enough, can use in very big range of lift, this also facilitates well water stream herein
Toward a farther distant place.
Impeller is centrifugal impeller, and impeller intake is upward；
Cap assemblies are located at the top of pump head, and cap assemblies include pump cover, lid axis, bearing, and pump cover and the pump housing are locked by fastener
It fastens, gasket or sealing ring is set on the contact surface of pump cover and the pump housing, several inlet openings, bearing setting is arranged in pump cover side
The table upper end in pump cover, lid axis upper end are arranged in bearing, and lid axis lower end also is provided with square toes or square inner bore is used for and pump shaft axis
To positioning and be sequentially connected；Because this immersible pump is modularized design, pump cover needs are easy to disassemble, and need for end
Pump shaft provides axially position, and radial support, otherwise entire immersible pump axis is unstable, and the present invention carries out radial support using bearing,
And the pump shaft and lid axis of end are also plug-in type design, install and facilitate in the extreme.The inlet opening of pump cover side undertakes
Filtering function prevents large-scale sundries or fiber from entering in pump, one layer of filter screen can also be arranged again outside by pump cover again, reach dual mistake
Filter purpose.
Effluent seat is located at the bottom of pump head, and effluent seat is locked by fastener with the pump housing and is arranged on the contact surface close
Water outlet is arranged in packing or sealing ring, effluent seat side, and water outlet is connect with outlet pipe, and effluent seat bottom end connects motor, motor
Output shaft pass through effluent seat after with pump shaft be sequentially connected.Effluent seat plays the role of connecting the pump housing and motor, effluent seat will be last
The water body that grade impeller is sent is transported in outlet pipe.
As optimization, cap assemblies further include bearing seal cover, sealing ring and axle envelope, and bearing seal cover is to be inverted hat, axis
It holds sealing cover to be mounted on from the bottom up in pump cover internal end surface, is arranged on bearing seal cover and pump cover inner face contact surface and seals
Circle, the position setting axle envelope that bearing seal is covered, passed through by lid axis.Pump cover as intake chamber, inside be filled with water, and axis
The performance for being easy to influence bearing with water if directly contacting is held, the sediment content in water is essentially consisted in, if very low, axis
Hold that it doesn't matter, if containing a small amount of silt, bearing cannot be in contact with water, otherwise be easy to damage, so
Setting bearing seal cover, sealing ring and axle envelope are for keeping apart in region at bearing and inhalant region in pump cover, middle cover axis
It is one quiet one dynamic sealing surface at the position of bearing seal cover, so needing dynamic sealing, is suitble to use axle envelope, also referred to as
Lip envelope.
As optimization, guide post component includes mobile jib, end to end bar and mounting base, and mobile jib is vertically arranged, and mobile jib both ends pass through
