- Capability Introduction
A. The LDR series Electrical Heating Steam Feeding Device is made up of the next main equipments:
The container is made of high quality seamless steel tube and armor plate for pressure vessel.
The electrical heating pipe is made of stainless steel tube. Once destroyed, you can replace it singly.
Water-feeding pump is able to endure high temperature.
We use a pressure controller on the device, in order to control the pressure of the steam.
We also use a liquid level controller, in order to control the level of the water.
B. So by using the equipments hereinbefore, the boiler can operating automaticlly. Such as:
Water feeding automatically: When the device is working, the level of the water in the container goes down continuously with steam’s outputting. Until it goes down to the middle level, the water-feeding pump turns on automatically, fills water into the container, till the normal working level (high level) is reached. Then the water-feeding pump will turn off. So the device can provide high-pressure steam by doing this case circularly.
Pressure control automatically: The device can cut off the heating power automatically when the pressure of the steam in the container rise to the high value that the pressure controller has been set. And it can also switch on the heating power automatically when the pressure goes down to the low value. So the device can output steam in an almost constant pressure.
Safety pressure control automatically: When the device has an error and can’t cut off the heating power automatically when the pressure of the steam in the container rise to the high value that the pressure controller has been set. The safety pressure control can cut off the heating power automatically in order to assure the operators and device’s safety.
Protect itself without water feeding: When the water level in the container goes down to the low level on account of causation unexpected, the device can cut off the heating power, in order to prevent the electrical heating pipe groupware from being destroyed because of lacking water.
Protect itself when pressure beyond range: In order to assure the operators and device’s safety, the safety valve will open up, when the pressure of the steam in the container rise to the value that the safety valve has been set on account of causation unexpected.
