Abstract

The invention relates to the technical field of flash drum pump units, in particular to an efficient combined type flash drum pump unit. The efficient combined type flash drum pump unit comprises a flash drum and a cylinder body of a low-pressure circulation cylinder. The flash drum is connected with a liquid supply pipe through an electric pilot valve. A filter is mounted at the end, away from the electric pilot valve, of the liquid supply pipe. The filter is connected with a liquid level valve and a solenoid valve through a pipeline. The solenoid valve is connected with a throttle valve through the pipeline. The throttle valve communicates with the interior of the cylinder body through the pipeline. The liquid level valve communicates with the interior of the cylinder body through the pipeline. A liquid supply throttle pilot valve is connected to the liquid level valve and is connected with a floating ball valve through the pipeline. The efficient combined type flash drum pump unit is convenient to use, and a liquid refrigerant can be made to enter the low-pressure circulation cylinder when a failure happens, so that the work delay brought by maintenance is reduced, the time consumption can be reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a flash barrel pump unit, in particular to a high-efficiency composite flash barrel pump unit. Background technique [0002] The compound flash barrel pump unit can be used to remove the flash gas generated by the liquid refrigerant after passing through the throttling device. After the liquid refrigerant enters the flash barrel and is separated, it enters the low-pressure circulation barrel through the pipeline. However, in the prior art, there is only one passage for the liquid refrigerant to enter the low-pressure circulation barrel, so that when the pipeline fails, the liquid refrigerant cannot enter the low-pressure circulation barrel, which not only leads to work delays, but also wastes time. Contents of the invention [0003] The purpose of the present invention is to solve the problem in the prior art that the pipeline between the low-pressure circulation barrel and the flash evaporation barrel ...
