Description
Technical field
The invention belongs to Hydraulic Power System technical field, relate to a kind of hydraulic equilibrium adjustment method of pipe system.
Background technology
Pressure Drop refers to two differences with the force value of pressure face, reflects the situation of change of pressure at one section of pipeline.That is, Pressure Drop refers to pressure reduction, refers generally to the pressure that fluid loses through certain container or equipment etc.Such as, equal upstream pressure through the Pressure Drop of an equalizing valve and deduct downstream pressure.
The flow regulation of an equalizing valve during with equalizing valve adjust flux, creates change at valve and ducted Pressure Drop, changes the Pressure Drop at other equalizing valve two ends, so can change the flow in modulated valve.Existing way is repeatedly regulated by equalizing valve.
Its publication number of Chinese patent CN100363169C provides one " device for the flow and/or pressure that regulate fluid ", its first valve is furnished with the control device on the pipeline being arranged on connection two reservoirs, the Laval nozzle being arranged on the downstream of described first valve is furnished with an electric Pressure Drop sensor, second valve being furnished with a control device is connected between the downstream part of described Laval nozzle and a vent orifice element, selective laser sintering system is designed to receive numerical value that Pressure Drop sensor reads and can drives two control device of two valves, this just makes it possible to the flow and/or the pressure that regulate the fluid carried to the second reservoir from the first reservoir.
Although above-mentioned documents regulates flow and pressure, it is carry out regulating for an independent valve.Multiple valves in parallel in system are needed to carry out test one by one regulate, also exist equally and regulate loaded down with trivial details problem.
Summary of the invention
The object of the invention is the problems referred to above existed for prior art, provide a kind of and debug hydraulic equilibrium adjustment method that the is quick and pipe system that applicability is high.
Object of the present invention realizes by following technical proposal: a kind of hydraulic equilibrium adjustment method of pipe system, described pipe system comprises water inlet pipe and return pipe, some user sides are parallel with between described water inlet pipe and return pipe, described each user side place all has the equalizing valve that can regulate its bypass flow, described water inlet pipe place also has the cooperation valve that can regulate whole water inlet pipe flow, it is characterized in that, this adjustment method comprises the following steps:
A, debugging prepare: common pressure reduction tester, as with reference to valve, is connected to reference to valve place by the equalizing valve choosing least significant end user side place in pipe system simultaneously;
B, measure with reference to valve pressure reduction: with reference to the flow regulation of valve place terminal temperature difference end to its design load, measured reference valve by common pressure reduction tester, this result gives the pressure reduction △ pR of METHOD FOR CONTINUOUS DETERMINATION, then fixes on this position with reference to the block of valve;
C, compensating differential pressure: open the equalizing valve with terminal temperature difference end neighboring user end place, measured with reference to valve by common pressure reduction tester, when regulating the flow with terminal temperature difference end neighboring user end, if with reference to valve place pressure reduction and △ pR variant, open cooperation valve until the pressure reduction with reference to valve place remains on △ pR, then the equalizing valve at the third party end place adjacent with terminal temperature difference end is opened, by that analogy.
Choose the equalizing valve at terminal temperature difference end place as with reference to valve, utilize common pressure reduction tester to adopt common method of testing to obtain the Pressure Drop △ pR at reference valve place, the aperture then with reference to valve keeps locking.Open in pipe system the penultimate user side place equalizing valve being close to terminal temperature difference end, again measured with reference to valve by above-mentioned pressure reduction tester, obtain the pressure reduction with reference to valve place.If pressure reduction and the △ pR of measurement are variant, then open cooperation valve thus change the pressure reduction with reference to valve place, making its pressure reduction remain on △ pR.
Then open the equalizing valve at third from the bottom user side place, again measured with reference to valve by above-mentioned pressure reduction tester, obtain the pressure reduction with reference to valve place.If pressure reduction and the △ pR of measurement are variant, then open cooperation valve thus change the pressure reduction with reference to valve place, making its pressure reduction meet reference point scope.Then open the equalizing valve at a fourth from the last user side place, value to all equalizing valves all regulate complete.In last whole system, the equalizing valve pressure reduction at all user side places is substantially identical.
In the hydraulic equilibrium adjustment method of above-mentioned pipe system, the described pressure reduction with reference to valve is 3KPA.
In the hydraulic equilibrium adjustment method of above-mentioned pipe system, if in described step B with reference to valve standard-sized sheet time and pressure reduction is greater than 3KPA, using with reference to valve standard-sized sheet time pressure reduction as reference point.
In the hydraulic equilibrium adjustment method of above-mentioned pipe system, the equalizing valve debugged in described step C is held open state.Such energy ensures that the equalizing valve at each user side place its pressure reduction after debugging is consistent substantially.
In the hydraulic equilibrium adjustment method of above-mentioned pipe system, in described step C, commissioning staff A carries out adjustment to cooperation valve and makes to remain on △ pR with reference to pressure reduction before and after valve, commissioning staff B intercom informs commissioning staff A with reference to the numerical information of valve place current differential pressure, and commissioning staff C opens each user side place equalizing valve and makes the flow of each user side reach its design load.Because user side each in pipe system is distant, the pressure reduction of other commissioning staff with reference to valve place can easily be informed by intercom.
Compared with prior art, the hydraulic equilibrium adjustment method of this pipe system does not need equalizing valves all in Analytical system one by one, avoids carrying out for a long time preliminary " scanning ", and each equalizing valve only need adjustment once, which reduce the time needed for system balancing pressure reduction, debug fast and convenient.
Meanwhile, it can reduce the energy consumption of water pump by the Pressure Drop reducing equalizing valve, Ordination of pump is excessive can be compensated on main equalizing valve, so can replace with less water pump, reduces pipe system cost.
In addition, balance pressure reduction can carry out stage by stage along with erection schedule, without the need to readjusting the system in whole building after completion of works, has higher practical value.
