Abstract
The invention provides a method for judging idle running of a positive-pressure dense-phase bin pump. The method is characterized by comprising the following steps: 1, opening a feeding valve and a pressurizing valve, inflating a pump body by using an air storage tank, and starting a timer T when the pressure of the pump body reaches P1, wherein the P1 is the maximum value of fluidized pressure of the pump body to materials; and 2, opening a discharging valve, ending timing when the pressure of the pump body is less than P2, judging whether the timing time obtained by the timer T is less than the reset value K or not, and if so, judging idle running of the positive-pressure dense-phase bin pump, otherwise, resetting the timer T, wherein the P2 is the pressure value of the pump body after all the materials in the pump are conveyed and the set value K is the time of reducing the pressure of the pump body from the P1 to the P2 during load running of the positive-pressure dense-phase bin pump. The method can judge whether idle running or not of the positive-pressure dense-phase bin pump by time and is effective and accurate, so the service life of equipment is prolonged and the operating cost of the bin pump is greatly reduced.
Description
Technical field
The present invention relates to a kind of whether method of no-load run of pressurized seal storehouse pump of judging.
Background technology
The storehouse pump is a kind of reliable close phase dynamic pressure Pneumatic conveyer of (about 700kPa following) conveying powder material under high pressure.Because admittance or the cloudy fork level-sensing devices of adopting, result of use is not very desirable, causes knowing the inner material level information of storehouse pump, whether just can't accurately grasp the storehouse pump at run with load yet more.The storehouse pump works long hours at light condition, not only can increase equipment attrition, reduces service life, also can waste mass energy.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively judge the whether method of no-load run of pressurized seal storehouse pump.
In order to achieve the above object, technical scheme of the present invention has provided the decision method of a kind of pressurized seal storehouse pump no-load run, this pressurized seal storehouse pump comprises the pump housing, the pump housing connects ash bucket by inlet valve and blow off valve, discharging behind the pump housing connection bleeder valve, the pump housing also connects storage tank by pressurizing valve, it is characterized in that step is:
The present invention judges whether no-load run of pressurized seal storehouse pump by the time, effectively and accurately, has not only prolonged service life of equipment, and has greatly reduced the operating cost of storehouse pump.
Description of drawings
Fig. 1 is the storehouse pump configuration scheme drawing among the present invention;
Pressure time curve when Fig. 2 is the storehouse pump operation;
Fig. 3 is the diagram of circuit of the decision method of a kind of pressurized seal provided by the invention storehouse pump no-load run;
The specific embodiment
For the present invention is become apparent, hereby with a preferred embodiment, and cooperate accompanying drawing to be described in detail below.
As shown in Figure 1, the decision method of a kind of pressurized seal provided by the invention storehouse pump no-load run, pressurized seal storehouse pump wherein comprises the pump housing 5, the pump housing 5 connects ash bucket 6 by inlet valve 3 and blow off valve 4, the pump housing 5 connects bleeder valve 2 rear dischargings, and the pump housing 5 also connects storage tank 7 by pressurizing valve 1.
Its working process is: when storehouse pump material advances to expire, close inlet valve 3 and the blow off valve 4 of this storehouse pump, and unlatching pressurizing valve 1, to this storehouse pump inflation, make goods fluid pressurization wherein, when pressure reaches setting value P1, open the bleeder valve 2 of storehouse pump, material begins to carry in the pump of storehouse, until the storehouse internal pressure is down to P2, mass transport is complete in the storehouse.
As shown in Figure 2, T (0,0)-T (1,1), T (2,0)-T (2,1) and T (3,0)-T (3,1) be the pressurization link of storehouse pump, in this stage, open pressurizing valve 1, to the inflation of storehouse pump, make goods fluid pressurization wherein, make pressure reach setting value P1.
T (1,1)-T (1,2), T (2,1)-T (2,2) and T (3,1)-T (3,2) is the discharging link of storehouse pump, when pressure reaches setting value P1, open the bleeder valve 2 of storehouse pump, material begins to carry in the pump of storehouse, until the storehouse internal pressure is down to P2, mass transport is complete in the storehouse.
T (1,2)-T (2,0) and T (2,2)-T (3,0) is the charging link of storehouse pump, in this stage, opens inlet valve 3 and the blow off valve 4 of this storehouse pump, when storehouse pump material advances to expire, closes inlet valve 3 and the blow off valve 4 of this storehouse pump.
In Fig. 2, T (1,1)-T (1,2) be the discharging link of storehouse pump no-load run, T (2,1)-T (2,2) and T (3,1)-T (3,2) be the time of the discharging link of storehouse pump run with load, apparent, T (1,1)-T (1,2) discharging time is less than T (2,1)-T (2,2) or T (3,1)-T (3,2) discharging time based on this, the invention provides such as the whether method of no-load run of pressurized seal storehouse pump that judges, in conjunction with Fig. 3, the steps include:
Claims (1)
1. the decision method of a pressurized seal storehouse pump no-load run, this pressurized seal storehouse pump comprises the pump housing (5), the pump housing (5) connects ash bucket (6) by inlet valve (3) and blow off valve (4), the pump housing (5) connects the rear discharging of bleeder valve (2), the pump housing (5) also connects storage tank (7) by pressurizing valve (1), it is characterized in that step is:
