Abstract
The utility model discloses a heating medium pressure device, which comprises high-temperature control valve, a disconnecting valve and a heating medium oil tube. A booster pump is arranged in front of the high-temperature control valve. A variable-frequency controller is arranged on the booster pump. A pressure sensor is arranged on the glycol steam outlet of an evaporator. The transducing signal of a pressure transducer is connected with the variable-frequency controller. The variable-frequency controller controls the rotation rate of the booster pump, thus controlling the flow of the heating medium. The heating medium pressure device is controlled automatically in a variable-frequency way, which is operated and installed conveniently.
Description
Technical field
The utility model relates to a kind of intermittently heating agent supercharging device of the daily production of polycondensation of polyester vacuum system that is applicable to.
Background technique
Intermittence, polyester production device vacuum system ethylene glycol steam generator was because the heat supply fluctuation is bigger at present, the people causes the ethylene glycol vapor pressure low as can't guarantee the normal heat supply of vaporizer when heating agent pressure is low, and fluctuations of vacuum is bigger, do not reach manufacturing technique requirent, influence quality of product.
Summary of the invention
The purpose of this utility model is to provide a kind of stable for the deficiency that solves above-mentioned technology, and it is little to fluctuate; Frequency conversion is controlled automatically, operation, heating agent supercharging device easy for installation.
In order to achieve the above object, a kind of heating agent supercharging device that the utility model is designed, comprise high temperature modulating valve, stop valve and heating agent oil pipe, it is characterized in that before the high temperature modulating valve, being provided with suction booster, be used for strengthening when heating agent pressure hangs down and enter vaporizer heating agent flow, on suction booster, be provided with frequency-variable controller, on the ethylene glycol steam outlet of vaporizer, be provided with pressure transducer, the transducing signal of pressure transducer is connected with frequency-variable controller, by the rotating speed of frequency-variable controller control suction booster, thus the flow of control heating agent.
During work, ethylene glycol steam delivery pressure control frequency-variable controller and control valve opening by vaporizer, the ethylene glycol vapor pressure, low big high temperature modulating valve and the raising suction booster rotating speed opened, ethylene glycol vapor pressure height, turn the high temperature modulating valve down and reduce revolution speed, thereby it is fixed to guarantee that stablizing of vaporizer heat supply reaches ethylene glycol vapor pressure weighing apparatus.
The resulting a kind of heating agent supercharging device of the utility model, stable, it is little to fluctuate; Frequency conversion is controlled automatically, operation, easy for installation.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Wherein: frequency variator 1, suction booster 2, high temperature modulating valve 3, stop valve 4, pressure transducer 5, heating agent oil pipe 6, ethylene glycol steam outlet 7, vaporizer 8.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, a kind of heating agent supercharging device that present embodiment is described, comprise high temperature modulating valve 3, stop valve 4, heating agent oil pipe 6 and vaporizer 8, it is characterized in that before high temperature modulating valve 3, being provided with suction booster 2, be used for strengthening when heating agent pressure hangs down and enter vaporizer heating agent flow, be connected with frequency-variable controller 1 being provided with the transducing signal that is provided with pressure transducer 5, pressure transducer 5 on frequency-variable controller 1, the ethylene glycol steam outlet 7 on the suction booster 2 at vaporizer 8, by the rotating speed of frequency-variable controller 1 control suction booster 2, thus the flow of control heating agent.
During work, ethylene glycol steam delivery pressure control frequency-variable controller 1 and control valve opening by vaporizer 8, the ethylene glycol vapor pressure, low big high temperature modulating valve 3 and raising suction booster 2 rotating speeds opened, ethylene glycol vapor pressure height, turn high temperature modulating valve 3 down and reduce revolution speed, thereby stable, the ethylene glycol vapor pressure weighing apparatus that guarantee vaporizer 8 heat supplies are decided.
