Abstract
The utility model belongs to the technical field of boilers and relates to a vacuum-pumping system for a vacuum hot water boiler. The vacuum-pumping system aims at solving the problems that after a vacuum of an existing vacuum hot water boiler is damaged, a new vacuum can not be formed by vacuum-pumping until the vacuum hot water boiler is waited to be cooled, so that using of the vacuum hot water boiler by users is affected. The vacuum-pumping system comprises a vacuum pumper communicated with the vacuum hot water boiler, and further comprises a condenser communicated with a pipeline of the vacuum hot water boiler. The condenser is communicated with the pipeline of the vacuum pumper. By adopting the technical scheme, the technical problem can be effectively solved.
Description
Technical field
The utility model belongs to the boiler technology field, relates to a kind of vacuum hot water boiler pumped vacuum systems.
Background technology
Vacuum hot water boiler is subject to market and uses widely with efficient energy-saving, the safe advantage of use.Keeping vacuum in the stove during vacuum hot water boiler operation, is the leakage of trace immediately, all can have a strong impact on the operation of vacuum hot water boiler, and must again form vacuum could normal operation.Vacuum hot water boiler on the domestic market mode that again forms vacuum in service is to adopt vavuum pump directly to bleed, the specific works mode is: force to stop using during the vacuum hot water boiler operation, wait for that drop in temperature is after the permission operating temperature of vavuum pump in the stove, opening vavuum pump bleeds, close vavuum pump after qualified, restart boiler operatiopn.The shortcoming of this mode is, is high-temperature water vapor in the boiler, needs could open vavuum pump behind the temperature lowering water steam-condensation, need to wait as long for the boiler cooling, can not vacuumize continuously, and equipment can not use during this period of time, has a strong impact on user's use.
The utility model content
Technical problem to be solved in the utility model is that existing vacuum hot water boiler is after vacuum breaking, the necessary grade after cooling, just can vacuumize to form new vacuum, affect the problem that the user uses, and provide a kind of vacuum hot water boiler pumped vacuum systems for this problem.
The utility model solves the problems of the technologies described above by the following technical programs:
A kind of vacuum hot water boiler pumped vacuum systems comprises the vavuum pump that is communicated with vacuum hot water boiler, it is characterized in that this system also comprises and the condenser of vacuum hot water boiler pipeline communication, and described condenser is communicated with vacuum-pump line.
The general employing of the formation of new vacuum vacuumizes, the utility model has been set up the condenser with the vacuum hot water boiler pipeline communication, guarantee that vavuum pump only extracts the gas that has passed through cooling processing, ensured the normal operation of vavuum pump, like this, the technical staff waits for that with regard to not needing drop in temperature vacuumizes vacuum hot water boiler again in the vacuum hot water boiler after zone of reasonableness, even if there is the leakage of trace in vacuum hot water boiler, also can guarantee the normal operation of vacuum hot water boiler.
In addition, this system also comprises the pipe electromagnetic valve on the pipeline that is arranged on pressure inductor, the pressure signal switch that is connected with pressure inductor, the condenser magnetic valve in the vacuum hot water boiler and is arranged on connection condenser and vacuum hot water boiler, and described pipe electromagnetic valve and condenser magnetic valve all are connected in series with the pressure signal switch;
Condenser outlet one end is communicated with vacuum hot water boiler by return duct, and return duct is communicated with a side with the condenser outlet and takes the shape of the letter U.
The gas of processing through condenser mainly is divided into the liquid water vapour of condensable one-tenth (following with the water replacement) and can't condenses into liquid incoagulable gas, incoagulable gas is discharged by vavuum pump, and the water vapour after condensing can return to vacuum hot water boiler, in condenser working, pressure in the condenser can change, serious will cause aqueous reflux, condenser outlet one end by return duct with after vacuum hot water boiler is communicated with, return duct can be arranged to U-shaped with the shape that the condenser outlet is communicated with a side, thereby the pressure reduction of condenser internal pressure and return duct hydraulic pressure can be communicated with the condenser outlet by return duct that water column balances in the U-shaped pipe of a side.
Further, the utility model also makes the operation automation of vacuum hot water boiler pumped vacuum systems, pressure inductor is set in vacuum hot water boiler, the pressure signal switch is connected with pressure inductor, pipe electromagnetic valve and condenser magnetic valve all are connected in series with the pressure signal switch, after pressure in the vacuum hot water boiler is elevated to a certain degree, pressure inductor makes the pressure signal switch opens, thereby condenser magnetic valve and pipe electromagnetic valve are all opened, after vavuum pump is also opened, whole vacuum hot water boiler pumped vacuum systems comes into operation, certainly, vavuum pump can be opened by pressure signal switch control, also can after condenser magnetic valve and pipe electromagnetic valve are opened, open again.
