SU6225A1 - Pumping device with filtration and heated fluid injection - Google Patents

Description

The proposed pumping device TBO with filtration and heating of the liquid fluid is intended to hydrate, for example, the chemical industry, on sieges {(n cannon-carbon dust during the cutting machines operation using sprayed bauds, to burn all kinds of liquid fuel under the boilers and furnaces, feeding boilers) , for mechanical: spraying of liquid fuel on steam locomotives and steamers, etc.

FIG. 1 and 2 of the drawing shows a longitudinal and transverse sections of the proposed pumping device with filtration and heating of the injected fluid.

The device consists of a pumping unit (steam, centrifugal and gear pumps) installed on a cast-iron or iron hollow foundation, which sucks the liquid intended for spraying or flow from pipeline 2, and feeds through pressure through the discharge pipe 3 and outlet 7 into the hollow foundation. A vessel consisting of two side chambers L and B with settling tanks and air caps 16 and a middle chamber C enclosing the tubes 11 is connected to the pumping cylinder through the discharge pipe 3. The latter are reported through filters 5 of camera A and B. The liquid enters pipeline 8 for use ie i.e. spraying or feeding boilers. The fluid on its way through pipes 11 is heated by waste steam from the steam pump through a three-way valve 17 to pipe 12, where heat is supplied to pipes P. The middle chamber C is equipped with drain pipes 13 and is connected to pipelines 12-to bring in some steam from the steam pump cylinder 1. The liquid condenses and leaves through the waste pipes 13.

If necessary, preheating the liquid during the stop

a steam pump or a fifacoca electric pump with a three-way water valve 17, respectively, rotates and, through a valve 18, receives hot water or steam for heating, which is directed by pipe 12, around the pipes 11, gives off heat and leaves used through pipes 13. For mitigate pump jolts and for uniform pressure of the entire system, there are two air buffers (pillows) in caps 16 and 16. Mechanical impurities in the pumped liquid (and with oils and water) remain in the bottom of Trap sumps 9 and 9; From there, they are lowered by cranes 10 and 10 as needed. There is a pressure gauge 14 for measuring pressure and a thermometer 15 for measuring temperature. The pump unit works automatically, and the pressure can be regulated by means of an M4ecKoro valve 4, which increases as the pressure rises above the allowable limit. opens and passes the liquid into the suction pipe 2 through the pump 1 and the pipe 3 back into the automatic valve or into the pipeline 8 completely, if the pressure in it decreases. Thanks to the automatic valve, the consumer receives a fluid of the same pressure; B, in case of complete closure of the pipe: level 3 or 8, the pump unit works normally without an increase in pressure and without damage to the installation and pipes. To clean the pipe side 11 and filters 5 and 5 from scale and dirt, two covers 6 and 6.

Patent Subject

Pump device With filtration and heating of the injected fluid, characterized by the use of an injection pipe connected to the pump cylinder of a 3-vessel, consisting of two side chambers A and M with settling tanks 9 and air caps 16 and the middle chamber - C, tube 11, coo6i4afcf through filters 5 above & decal chambers A and B, energy supply with drain pipes fS and 12 with pipelines for supplying it with steam from the steam pump cylinder T, or for supplying fresh steam or air vod1, -at off When the pump is driven, or when it is ps driven by an electric motor or an e-fast drive, the 1 ka cylinder is fed with the fluid to be pumped through pipe 2, which is connected to the pressure pipe 3 above via the overflow valve, spring valve 4, to maintain constant The pressure in the pressure pipes and in the vessel itself, for which, a manometer 14 and a thermometer 15 are installed on the vessel to measure the pressure and temperature of the injected fluid.
