Problems solved by technology

[0006] The portable circulating water cooling system uses circulating water to cool external equipment. It has the advantages of small size (usually its internal water storage tank volume is less than 30L) and does not need an external water source. It is an energy-saving product, but because it is generally used in a relatively Poor construction sites are likely to cause circulating water pollution. At present, there are still the following disadvantages:
[0007] 1. There is only one circulating cooling circuit, and there is no emergency measure when the equipment fails;
[0008] 2. There is only one water storage tank, and the maintenance work must be operated in a shutdown state, which affects the efficiency of equipment use;
[0009] 3. The circulating water pump is the most easily damaged part in the whole device. There is no filter at the water inlet end, which is easy to damage the equipment, and there is only one circulating water pump, and the system equipment needs to be shut down for regular maintenance, so it cannot be used continuously for a long time

Embodiment 1

[0038] Such as Figure 5 As shown, the portable circulating water cooling device 2 of the present invention has two water circulation loops, including a first circulating water pump M1 and a second circulating water pump M2. After the first circulating water pump M1 and the second circulating water pump M2 are connected in parallel, the water circulation pipeline It is connected in series with the argon arc welding machine, the cooling device 24 and the water storage tank to form a circuit.

Embodiment 2

[0040] Such as Figure 6 As shown, the portable circulating water cooling device 2 of the present invention has two water circulation loops, the circulating water pump includes a first circulating water pump M1 and a second circulating water pump M2, and the water storage tank includes a first water storage tank and a second water storage tank. The first circulating water pump M1, the argon arc welding machine, the cooling device 24, and the first water storage tank are connected in series through the water circulation pipeline to form a loop; the second circulating water pump M2, the argon arc welding machine, the cooling device 24, and the second water storage tank pass through The water circulation pipelines are connected in series to form a loop.

Embodiment 3

[0042] The only difference from Embodiment 1 and Embodiment 2 is that the portable dual-pump circulating water cooling system of the present invention further includes a central controller connected to the first circulating water pump M1 and the second circulating water pump M2 respectively.

Abstract

The invention discloses a portable double-pump circulating water cooling system and a cooling method. The portable double-pump circulating water cooling system comprises water storage tanks, circulating water pumps, radiators and water-circulating pipelines, wherein the circulating water pumps are a first circulating water pump and a second circulating water pump, and thereby two water-circulating loops are formed. The invention has the following advantages: the double circulating water cooling loops can ensure that when one of the water pumps goes wrong or is overhauled, equipment can uninterruptedly operate; with flow sensors and a central controller, the portable double-pump circulating water cooling system can detect flow to judge the abnormal state of one of the water pumps and automatically switch the water-circulating loops; with an alarm and a display, the portable double-pump circulating water cooling system can display the current circulating loop and the current flow and give the alarm when flow is abnormal; and with filters, the portable double-pump circulating water cooling system can effectively control the quality of water entering the water pumps, so that the fault rate of the water pumps can be decreased.

Description

[0001] technical field [0002] The invention relates to a portable circulating water cooling system for providing a cooling water source for a welding machine, in particular to a portable double-pump circulating water cooling system. The present invention also relates to a double-pump circulating water cooling method based on the above system. Background technique [0003] Portable circulating water cooling device (commonly known as cooling water tank) is an advanced cooling equipment using circulating water, which can provide a good source of cooling water for plasma welding machines, argon arc welding machines and other welding machines that require water cooling It is suitable for supporting systems of other electrical appliances and mechanical equipment that need circulating water cooling. [0004] Such as Figure 1 to Figure 3 As shown, the structure of the portable circulating water cooling device 1 generally includes: a casing 11, a water storage tank 12, a circ...
