Abstract
The utility model relates to a water returning pump which is used for a high pressure steam boiler. A hot steam water pump which is adopted is composed of a piston pump and a unidirectional valve. The hot steam water pump can be used for pumping water and pumping steam so that the steam boiler can reach closed circuit circulation. The temperature of returning water and the pressure of a pipeline are fully utilized. The existing water returning pool and the existing treating water device are reduced. So investment and the water used for circulation can be not only saved, but also heat efficiency can be improved by 10% to 15%. The pump can continuously work under high temperature and high pressure for a long time.
Description
The xeothermic circulatory system of hot high pressure carbonated drink pump is particularly useful for the waterback pump of high pressure steam boiler.
The thermal cycle of conventional steam boiler is that backwater is recovered in the back pool, water is pumped into to continue the use of heating heating network in the boiler after cooling again.Like this, because existing waterback pump can not pump into boiler simultaneously with hot vapour, water, the temperature of backwater has been slatterned in vain.
The purpose of the invention is to make a kind of hot high pressure carbonated drink pump, and the backwater of boiler, vapour are lowered the temperature without back pool, can directly backwater be pumped into boiler, reduces thermal loss, strengthens the thermal efficiency, realizes the closed-circuit of steam boiler.
The structural principle of the invention is to adopt a kind of reciprocating pump to make the waterback pump of steam boiler, and settled the one-way valve (reverse stop valve) of two pipelines in this pump rear and front end, the conducting direction of two valves of every side is consistent, by the piston motion in the reciprocating pump, in the pump housing, produce different pressure, and then the conducting that impels valve with close, realize not losing under the prerequisite of temperature and pressure of backwater, vapour with this and carry out enforceable closed-circuit.
The advantage of the invention is:
1, this pump is compared with other pump and is had heat-resisting advantage, can work under high temperature vapour, water condition, has greatly saved the energy, and operating temperature range can be more than 100 degree.
2, this pump can work long hours under High Temperature High Pressure continuously.
3, this pump can overcome other pump can only pump water can not mercury vapour or the shortcoming of vapour, water mixture, vapour, the water mixture of steam boiler backwater directly can be pumped into boiler, realize the closed-circuit of steam boiler then.
4, adopt this pump can make the heat circulating system of steam boiler reduce back pool and water treatment procedure, also saved a large amount of waters simultaneously, and can improve thermal efficiency 10-15%.
The embodiment of the invention is as follows:
Be described in detail the invention structure and working procedure in conjunction with the accompanying drawings.At the middle part of figure is reciprocating pump 5, its left and right sides is equipped with four one-way cocks 1,2,3,4, valve 1,2 joins in the left side of reciprocating pump and the terminal water return pipeline 9 in the heat supply network, the direction of two valves, 1,2 conductings is consistent, valve 3,4 communicates with boiler water pipe 10 on the right side of reciprocating pump, and two valves, 3,4 conducting directions are consistent.Have piston 6 to reciprocatingly slide in pump in this reciprocating pump 5, be embedded with at least one piston ring 7 at the edge of piston 6, piston 6 is to be moved by reciprocal pull bar 8 drives of reciprocating pump, and reciprocating pump 5 has four import and export to be connected with one-way cock 1,2,3,4 respectively.Its working procedure is to drive reciprocal pull bar 8 by exterior mechanical to move reciprocatingly, thereby drive piston 6 motions, when piston moves to position B by position A, the top volume of reciprocating pump 5 is drawn together greatly, pressure reduces, make one-way valve 1 conducting of terminal water return pipeline one side, the vapour in the water return pipeline 9, water mixture enter in the reciprocating pump, and this moment, one-way valve 2 was in non-return state.And the bottom volume of pump dwindles, pressure increases, and make one-way valve 4 conductings, and one-way valve 3 is in non-return state, at this moment original vapour, water mixture pressurized in reciprocating pump 5 enters connecting pipe 10 by one-way valve 4 and is pressed into boiler, and this moment, a stroke of reciprocating pump 5 was finished.Reciprocating pump 5 next strokes are to move to position A by position B, the first half volume of pump reduces like this, pressure increases, the Lower Half volume of pump is drawn together greatly, pressure reduces to cause one-way valve 2,3 conductings, one-way valve 1,4 is in non-return state, and the vapour in the water return pipeline 9, water mixture enter reciprocating pump 5 inside by one-way valve 2 like this, and vapour, the water mixture on reciprocating pump 5 tops was pressed into boiler owing to pressurized enters connecting pipe 10 by one-way valve 3 originally.Motion and so forth realizes the circulation of the closed type of steam boiler.
