Liquid Storage Tank, How to Reduce Costs and Increase Efficiency!

During the manufacturing of air conditioning compressors, did you encounter any  problems with the welding l iquid storage tanks ?

1  Liquid storage tank  is a key component in the air conditioning   compressor s

T he l iquid storage tank  is a key component in air conditioning   compressor s  y   is generally installed on the inhaler . Its main functions are：

(1) Stores liquid components of the refrigerant and reduces the load on the condenser 

(2) It acts as a liquid seal to prevent gas from entering the low-pressure compressor and producing liquid shock. Liquid shock mainly occurs in piston compressors because the refrigerant liquid (or lubricant oil) is sucked into the compressor, causing abnormal shock accidents to the compressor.

(3) It prevents the condensate from accumulating too much in the condenser, which can reduce the heat transfer area and affect the heat transfer effect of the condenser.

(4) It adapts to the load changes of the evaporator. When the evaporation load increases, the supply also increases and is supplied by the liquid in the liquid storage tank; when the evaporation load becomes smaller, the required liquid volume also becomes smaller, and excess liquids are stored in the liquid storage tank.

(5) It plays a certain role in silencing and filtering.

2. Welding problems of liquid storage tank

Currently, th e manufacturing de air conditioning compressor   l iquid storage tank s  mainly uses furnace brazing or arc welding. H owev er,   t he cost of the se pro cess es   is high. A rc welding produce s oxide scale and tiene low  yield , wh ile f urnace brazing   tiene a norte economic batch limit. A dd i t i on al ly,   b oth processes have environmental issues.

El o elding problems of liquid storage tank s a re as fo llows :

(1)  Alto  cost

F urnace welding power consumption is 0.4-0.5℃   per piece, and furnace preheating consumes 1200-1500℃, which consumes a lot of power.

(2)  Hi gramo h tem per a ture

  F urnace welding requ ires a hig h temperature ,  which   l eads   t o  frequent replacement de the ch ain hea t- resis tan t la y er y co mple x  disassembly

(3)  Ha o sh w o k ing conditi ons

  F urnace welding requires an operating temperature of 40-50℃.

(4)  Low  efficiency

  F urnace welding efficiency is 30s/piece.

(5)  Cannot be automated

(6)  Unst able  welding quality due to uneven solder filling.

To address these issues, Heron has developed and manufactured a high quality welding product that reduces costs and increases efficiency - medium voltage capacitor discharge (CD) welder for liquid storage tanks. The medium voltage capacitor discharge resistance welding process replaces the traditional brazing process, eliminating pollution and emissions, reducing energy consumption, and enabling clean production at room temperature throughout the process. This process eliminates energy consumption caused by solder and continuous heating, saving costs and being more environmentally friendly. The CD welder is low cost and suitable for small batch production, and it is fully automatic,eliminating the need for operators during and the welding process. The production cycle is 8s/unit, greatly improving production efficiency.
