Brief description of the drawings
Fig. 1: the structural representation of the high height above sea level lift of the utility model pressure piping long distance water transfer device.
Description of reference numerals:
Detailed description of the invention
Below in conjunction with Fig. 1, the utility model is described further:
As shown in Figure 1, a kind of high height above sea level lift pressure piping long distance water transfer device, comprise that parallel connection is provided with two aqueducts 12, aqueduct 12 is fetched water from pond 17, taking water flow as direction, on aqueduct 12, be provided with successively 18, self priming pump 1, strainer 2, outlet valve 3, inlet pressure transmitter 4, inlet valve 5, inlet voltage-stabilizing device 6, electric reciprocating pump 7, outlet stable-pressure device 8, outlet pressure transmitter 9, flap valve 10 and outlet valve 11.
Aqueduct 12 between outlet valve 3 and inlet pressure transmitter 4 is provided with the first bypass duct, and the first bypass duct is provided with pressure retaining valve 13.Aqueduct 12 between outlet pressure transmitter 9 and flap valve 10 is provided with the second bypass duct, is provided with successively seal valve 14 and wearing and tearing valve 15 on described the second bypass duct, and seal valve 14 is between wearing and tearing valve 15 and aqueduct 12.Many aqueduct 12 outputs point in parallel shares a plug 16.
The high height above sea level lift of the utility model pressure piping long distance water transfer device operating principle is as follows:
1,, while starting the operation of single pump/double pump, open pump operated mode identical.When double pump operation, first open a wherein electric reciprocating pump 7 of pump, after last electric reciprocating pump 7 shows operation pressure stabilization, restart another.
2, start the front Power supply of confirming, confirm that each valve state is normal, effective.
3, electric reciprocating pump 7 is carried out to hand turning three to five circles, for guaranteeing jiggering staff's safety, during jiggering, forbid the electric equipment in system to make any operational motion.
Hand turning three to five circles are the preparation that starts electric reciprocating pump 7, are to ensure electric reciprocating pump safety, the normal prerequisite starting.Because the running status of electric reciprocating pump 7 is high pressure kinetic energies, before starting, jiggering is whether motion between the moving component that whether is stuck, cooperatively interacts of the operation parts in order to check in electric reciprocating pumping system smooth, avoid starting in the jammed situation of operation parts of electric reciprocating pump in its system and cause electric reciprocating pump and system attachment impaired or injure staff around electric reciprocating pump.Electric reciprocating pump startup shroud car in the utility model is must obligato operation sequence.
4, confirm that whether each instrument valve duty and position be correct, seal valve 14 and wearing and tearing valve 15 should be in open modes.
5, start self priming pump 1, after inlet pressure transmitter 4 shows pressure stability, open pressure retaining valve 13, show pressure stability if open the rear inlet pressure transmitter 4 of pressure retaining valve 13, can start the auxiliary equipment of electric reciprocating pump 7.Startup electric reciprocating pump 7 is front must ensure that inlet pressure transmitter 4 shows that under pressure retaining valve 13 open modes force value arrives rated value and pressure stability, must ensure that auxiliary equipment is in normal operating condition.
6, start electric reciprocating pump 7.Whether normally now observe the pressure data that outlet pressure transmitter 9 shows, the pressure data that shows as outlet pressure transmitter 9 is abnormal and fluctuation is larger, should stop electric reciprocating pump 7, and ascertain the reason.
7, after electric reciprocating pump 7 starts, first close wearing and tearing valve 15, then close seal valve 14.Discharge and pressure that now electric reciprocating pump provides enter aqueduct main part.
8, when termination of pumping, should first open seal valve 14, then open wearing and tearing valve 15 and carry out pressure release, first stop main pump motor, stop successively auxiliary equipment and self priming pump.
The pipeline that seal valve 14 and wearing and tearing valve 15 are set has two effects:
1, start adjusting before operation and pipeline pressure release time out of service for aqueduct 12.Due to the existence of flap valve 10, when water pump is stopped, hydraulic pipeline forms the pressure differential of about 21MPa left and right in flap valve 10 both sides.In the time starting electric reciprocating pump water delivery, if there is no the setting of the pipeline of seal valve 14 and wearing and tearing valve 15, the water that electric reciprocating pump 7 is carried will directly enter aqueduct 12, require electric reciprocating pump motor hydraulic pressure in the pipeline that starts instantaneous institute work and must overcome 21MPa, cause equipment to start under the very large state of momentum.There are three shortcoming: a, may cause electric reciprocating pump motor normally not start in above situation; B, cause high-pressure hydraulic pump component or system attachment short application life.C, the permanent high-pressure hydraulic pump of startup in a manner described easily cause high-pressure hydraulic pump safe operation coefficient to reduce.
2, electric reciprocating pump and system attachment thereof are completed after maintenance, start electric reciprocating pump 7, make electric reciprocating pump 7 be provided with seal valve 14 and conduit running---the low pressure underrun of the valve 15 that weares and teares in its water delivery current process, to check the equipment performance after maintenance.
(1) the high height above sea level lift of the utility model pressure piping long distance water transfer device has solved high height above sea level under the severe physical geographic environment in Dongchuan region, high-lift, pressure piping water delivery problem, water delivery pipeline system uses primary pump to overcome the height above sea level discrepancy in elevation of 2070 meters, the highest operating pressure 21.3Mpa, minimum operating pressure 25.1Mpa, aqueduct total length 10.7km, 1,000,000 cubes/year of conveying capacitys, after being constructed and put into operation, for selecting the oepration at full load of factory, stuffed bun house Dongchuan mining company provides safeguard, other productions and life that the part water yield can be supplied stuffed bun house area are used, efficiently solve high hypo, water resources shortage regional industry water and people's livelihood problem of water consumption.
(2) the utility model arranges the parallel pipeline of many covers, except for increasing conveying capacity, meeting terminal water supply volume, can also do Emergency use, comprises a circuits for subsequent use; Start two circuits to improve the flow velocity of current in pipeline simultaneously, thereby play the effect of protection against cold and freezing conditions.
By reference to the accompanying drawings the utility model is carried out to exemplary description above; obvious realization of the present utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all in protection domain of the present utility model.
