Description

Самопишущие паромеры дл  автоматического указани  расхода пара при измерении его дроссельными приборами не обеспечивают автоматической поправки на давление, а многие самопишущие паромеры, искажа  действительный контроль за расходом пара на предпри ти х и дава  лишь приближенные результаты его расхода, регистрируют расход пара только при одном определенном давлении. В эксплоатацпонных же услови х давление пара колеблетс  иногда в весьма широких пределах. Таким образом, при пользовании паромерами такого типа необходимо отдельно фиксировать давление пара и затем производить последующие пересчеты, что требует непроизводительной траты времени. Между тем в эксплоатационных услови х весьма важен систематический и точный учет расхода параПредлагаемое устройство механического определени  расхода пара стран ет указанный недостаток.Recording steam meters to automatically indicate steam consumption when measured with throttle instruments do not provide automatic pressure correction, and many recording steam meters distort actual control over steam consumption at plants and give only approximate results of its consumption, record steam consumption only at one specific pressure. . In exploitation conditions, however, the vapor pressure sometimes fluctuates within very wide limits. Thus, when using steam generators of this type, it is necessary to separately record the vapor pressure and then carry out subsequent recalculations, which requires waste of time. Meanwhile, systematically and accurately taking into account steam consumption is very important under operational conditions. The proposed device for mechanical determination of steam consumption suffers from this drawback.

В предлагаемом устройстве св зь кинематической системы с датчиками давлени  и регул торами перепада дл  замера расхода насыщенного пара основана на уравнении расхода пара:In the proposed device, the communication of the kinematic system with pressure sensors and differential regulators for measuring the flow rate of saturated steam is based on the steam flow equation:

В устройстве, механически воспроизвод щем эту схему, движение указательной стрелки, сообщаемое ей перемещением рейки, должно быть пропорционально произведению квадратных корней из перепада давлени  и удельного веса измер емого пара, причем необходимо производить поправку на давление.

This is accomplished by a rocker, which is driven in a forward (preferably vertical) motion by a cam, which is controlled by pressure at the entrance to the throttle body, and a rotary motion around an axis moving from this pressure, by a cam, which is controlled by a differential pressure.
