Description
Technical field
The utility model relates to the optimize and improve of a kind of machine envelope flushing scheme PLAN53A, peripheral hardware pressurization space material storage tank provides clean liquid to annular seal space, circulation is completed by inside transfusion ring, the pressure of space material storage tank is greater than by sealing technology fluid pressure, reach the object of odd-job skill discharge, belong to chemical machinery field.
Background technology
In Chemical Manufacture, mechanical seal is the most frequently used seal form of chemical pump, but in use due to mechanical seal, to damage the leakage of the pump caused very common.Therefore, how correctly to install and use, Rational Maintenance mechanical seal to reduce leakage, preventing pollution, increasing economic efficiency, is an important process of chemical enterprise.
In order to need of production, some pump of the prior art have employed the seal form of two-shipper envelope band space material, and it is generally used for carrying and does not allow the poisonous, volatile of leakage, the medium that inflammable and explosive or value ratio is higher.Flushing scheme adopts PLAN53A scheme, supplement space material to be supplied by the external world, through air bag accumulator (after eliminating its fluctuation of pressure, seal inner transfusion ring by machine and complete its circulation, and the heat in circulation is removed by water cooling H Exch, finally be transported to machine sealing position to reduce seal face temperature, on guarantee seal face, fluid film is stable, stops solid impurities and oil coke to deposit medium in annular seal space.Also have the low warning device of pressure (PSL) in this blast cleaner envelope scheme, just can know the pressure state of fluid reservoir at control cabin, and also can observe its temperature and pressure at the scene when patrolling and examining, and then ensure that the Effec-tive Function of pump.
Existing machine envelope flushing scheme PLAN53A not only needs the flushing spacer fluid (being sent by petrol station) sent outside, also needs the devices such as air bag accumulator and pressure alarm.This not only adds input and operation cost, also operation and maintenance personnel are had higher requirement.
Utility model content
The purpose of this utility model is to provide a kind of fluid reservoir for the flushing of machine envelope to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of fluid reservoir rinsed for machine envelope, comprise tank body, wherein, the top of described tank body is provided with supplementary space material and adds entrance, cooling water outlet, nitrogen pressurization interface and TI heat indicator, site pressure table is provided with above the side of tank body, be provided with LSL liquid level low-side switch below the side of tank body, the bottom of tank body is provided with cooling water inlet, discharge side, space material entrance and space material outlet.Eliminate air bag accumulator, adding can TI heat indicator, the LSL liquid level low-side switch of remote transfer signal, LSL liquid level low-side switch and TI heat indicator can teletransmission to DCS, judge the running condition of machine envelope ancillary system thus: as explanation space material will be used up when its low liquid level warning, producers are reminded to supplement space material, but when supplementing very frequent, whether interior leakage can be sealed by inspection machine; As illustrated when temperature alarming, machine envelope is leaked, and leaks in tank, now answers maintenance down.
Preferably, described nitrogen pressurization interface is connected with pressure source, described pressure source comprises source of the gas two part, and one end of described source of the gas two part is connected with nitrogen pressurization interface by tracheae, and the other end of source of the gas two part is connected with a nitrogen header pipe by tracheae.Connect a road tracheae to fluid reservoir top place by nitrogen header pipe, decompression is carried out except water filtration (pressure can regulate as required) by source of the gas two part in centre
Preferably, manual replenisher is also provided with below the side of described tank body.Can also can manually mend when space material is not enough.
Preferably, liquid level sight glass is provided with above the side of described tank body.
Machine envelope flushing scheme PLAN53A after improvement, does not need the space material sent outside to rinse, does not need air bag accumulator to carry out voltage stabilizing yet, but utilize on-the-spot nitrogen to carry out voltage stabilizing.Also without pressure warning unit (not needing to receive middle control), but in order to easy manipulation and practical, adding can the heat indicator of remote transfer signal and liquid level switch low alarm system, and then the smooth operation sealing ancillary system for machine provides guarantee.
The beneficial effects of the utility model are mainly reflected in:
Scheme after being optimized by contrast more economically, operability also increases than before simultaneously: not only eliminate the transmission pump of outer liquor charging, pipeline, valve etc. (reduce leak source, reduce costs), but also eliminate air bag accumulator (needing periodic inspection, inflation) and pressure warning unit; Single pump ratio, merely add can the heat indicator of remote transfer signal and low liquid level switch, manual fluid infusion (oil) apparatus, and its cost is 1/3rd in former scheme through calculating; Operability is the sealing liquid pressure adjustable of nitrogen, and space material every platform pump is all isolated being independent of each other, and can manual fluid infusion (being equivalent to spare tank the same).
