Abstract
Očelom zariadenia na kontrolu chladenia je zamedziť možnému havarijnému stavu pri náhlom přerušení prietoku chladiacej vody. Uvedeného účelu sa dosiahne indikátorom prietoku chladiacej vody pozostávajúceho z teflónovej rúrky opatrenej na oboch koncoch kovovými medzikružiami, ktoré sú vodivo spojené s vyhodnocovacím zariadením. Zariadenie pre kontrolu chladenia vodou móže nájsť široké priemyselné využitie u všetkých zariadení chladených vodou s otvoreným okruhom.The purpose of the cooling control device is to prevent a possible emergency situation in the event of a sudden interruption of the cooling water flow. The stated purpose is achieved by a cooling water flow indicator consisting of a Teflon tube equipped at both ends with metal rings, which are conductively connected to the evaluation device. The water cooling control device can find wide industrial use in all open-circuit water-cooled devices.
Description
Vynález sa týká zariadenia na kontrolu chladenia vodou u prístrojov a zariadení s otvo- reným okruhom, v ktorých nie je možné priamo merať ich teplotu, príp. vyhodnotenie tejto teploty je pomalé.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for controlling water cooling in open circuit devices and apparatus in which it is not possible to directly measure their temperature or temperature. evaluation of this temperature is slow.
Doteraz sa ochrana zariadení chladených prietokov vody rieši meraním teploty chladenej časti zariadenia. Takýto spósob ochrany nie je dostatočne rýchly pri náhlom přerušení prietoku chladiacej vody.So far, the protection of cooling water flow devices has been solved by measuring the temperature of the cooled part of the equipment. Such a method of protection is not fast enough when the cooling water flow is abruptly interrupted.
Uvedenú nevýhodu v podstatnej miere odstraňuje zariadenie na kontrolu chladenia vodou podlá vynálezu, ktorého podstata spočívá v tom, že vo výtoku chladiacej vody je pevne uložená rúrka so záporným adhéznym napatím, výhodné z teflonu, opatřená na oboch koncoch kovovými medzikružiami. Kovové medzikružia sú vodivo spojené s vyhodnocovacím a zabezpečovacím obvodom. Výhodou zariadenia na kontrolu chladenia vodou je, že umožňuje okamžité vypnutie chráněného zariadenia z elektrickej siete pri náhlom přerušení dodávky chladiacej vody. V súčinnosti s teplomerom vybaveným indikáciou uvedenej teploty umiestnenej v ponornej nádržke umožňuje rýchlu a spolahlivú ochranu chladeného zariadenia pri přerušení dodávky chladiacej vody, resp. pri zoslabení prietoku.This disadvantage is substantially eliminated by the water-cooling control device according to the invention, wherein a negative-adhesion pipe, preferably of Teflon, is provided in the cooling-water outlet provided with metal annulus at both ends. The metal rings are conductively connected to the evaluation and safety circuit. The advantage of the water cooling system is that it allows the protected equipment to be shut down immediately from the mains when the cooling water supply is abruptly interrupted. In conjunction with a thermometer equipped with an indication of the indicated temperature located in the immersion tank, it allows quick and reliable protection of the refrigerated equipment when the cooling water supply is interrupted. flow reduction.
Na pripojenom výkrese je schématicky znázorněné zariadenie na kontrolu chladenia vodou.In the accompanying drawing, there is shown schematically a device for controlling water cooling.
Zariadenie pozostáva z výtokovej hadice 10, ktorá je připojená na výtok chladeného zariadenia K Vo výtokovej hadici 10 je uložená ponorná nádržka 2 s teplomerom 2 umožňujúcim merať a indikovat přednastavená hodnotu. Na konci výtokovej hadice 10 je vložená rúrka £ so záporným adhéznym napatím, výhodné teflonová, opatřená na oboch koncoch kovovými medzikružiami 4 a 5. Kovové medzikružia 4 a 5 sú vodivo spojené s tranzistorovým vyhodnocovacím obvodom 9.The device consists of an outlet hose 10 which is connected to the outlet of the cooled device 10. In the outlet hose 10 a submersible reservoir 2 is placed with a thermometer 2 allowing to measure and indicate a preset value. At the end of the outlet hose 10, the negative-adhesion pipe 8 is preferably inserted, preferably Teflon, provided at both ends with metal rings 4 and 5. The metal rings 4 and 5 are conductively connected to the transistor evaluation circuit 9.
Chladiaca voda vytéká z chladeného zariadenia 2· V ponornej nádržke 2_ sa meria teplota vody teplomerom 3, u ktorého je možné indikovat prednastavenú hodnotu skratovanim bázového prúdu tranzistora ]_ a následným přerušením zabezpečovacieho kontaktu 2· Teflonová rúrka 2, opatrerná na oboch koncoch kovovými medzikružiami 4 a 5 tvoří snímač indikátora prietoku. Kovové medzikružia 2 a A S1^ vodivo spojené s vyhodnocovacím tranzistorom 7_ a pri prietoku chladiacej vody vytvárajú obvod jeho bázového prúdu. Pri náhlom přerušení prietoku chladiacej vody spósobí indikátor prietoku okamžité prerušenie bázového prúdu tranzistora 7_ s následným přerušením zabezpečovacieho kontaktu 2«The cooling water flows out of the cooled device 2. In the immersion tank 2, the water temperature is measured by a thermometer 3, where a preset value can be indicated by shorting the base current of the transistor 1 and then interrupting the safety contact 2. and 5 forms a flow indicator sensor. The metal rings 2 and A ' s conductingly connected to the evaluation transistor 7 and the flow of cooling water form a circuit of its base current. When the cooling water flow is suddenly interrupted, the flow indicator causes the instantaneous interruption of the base current of the transistor 7, followed by the interruption of the safety contact 2 «.
Vynález móže nájsť široké priemyselné využitie u všetkých zariadení chladených vodou s otvoreným okruhom.The invention can find wide industrial applications in all open-circuit water cooled plants.
