Brief introduction of the multi-tube type
oil cooler
The tandem double cooler consists of two oil coolers and three - way valve units in the same area
The cooling load of the system, with the tube plate fixed at one end and floating at the other end, detachable tube bundle and water chamber box cover, facilitates cleaning, inspection and maintenance during operation.
Cooler material, according to the use of place, water system conditions can have a variety of choices. Material has all stainless steel, stainless steel carbon steel combination, carbon steel and copper combination.
Column and tube type cooler characteristics
1. The multi-tube cooler adopts the naked tube (with unrolled fin on the surface) type heat transfer tube, with high heat transfer coefficient of the outer film of the tube and strong anti-pollution ability.
2. The cooling pipe of the in-line tube oil cooler adopts high-quality copper pipe and is processed into finned radiator. The product has small volume and large heat exchange area.
3. The spiral flow baffle of the tubular cooler makes the cooled liquid spiral into a continuous and uniform rolling flow, overcoming the cold and heat generated by the folded flow baffle
Exchange efficiency.
4. The liner type cooler adopts the expansion type seal, which overcomes the undesirable change of material after high-temperature welding.
5. The in-line tubular cooler has good structural performance, stable sealing performance, high heat transfer efficiency, compact structure and small ground occupation.
Column and tube type cooler application
The series tube oil cooler is widely used in the thin oil lubrication system and in metallurgy, mining, cement, electric power, light industry, food, chemical industry, paper making and other industrial sectors
Hydraulic system used in the cooling system of lubricating oil, hydraulic oil and other industries.
Cleaning of the scale of the tube cooler
1. Physical cleaning method: if the pipe plate type is fixed, it can be rinsed with pump brush. If it is core-pulling type, it can be floating-head type
Pull the tube bundle out to flush; 2. Chemical cleaning: when scale accumulation changes from loose to dense and hard, mechanical cleaning method cannot achieve scale cleaning
The method of pickling should be adopted at this time. Hydrochloric acid dissolves calcium carbonate and magnesium carbonate scale easily without preheating
Acid solution. Although pickling can restore loose scale and normal state of the cooler surface well, hydrochloric acid can corrode the cooling copper pipe. In order to protect
The wall of the protecting cooler is not eroded by hydrochloric acid, and additives must be added in the acid wash solution, that is, substances that strongly delay the metal dissolution process. We chose to use
The additive was benzotriazole, namely bc-801 water stabilizer, with a concentration of about 3%. According to experience, if able to do mechanical cleaning on time, acid
Wash can 2a--3a once; On the contrary, it needs to be pickling once a year.
installation
The installation of cooler is divided into vertical cooler and horizontal cooler. The vertical cooler has the features of small required area and easy installation. Horizontal oil cooler is characterized by small pressure drop and strong water impact resistance. Therefore, vertical or horizontal oil cooler is selected correctly according to the requirements of different site, space height and service performance, which can better meet the needs of generating sets and other equipment.
(1) the cooler can only be put into use after the pressure test is qualified, and the front row can be used to store water inside.
(2) check whether the poured and empty valves are flexible, convenient and switch position, and whether the pressure gauges and thermometers are all installed.
(3) check whether the foundation and support are firm, and whether the bolts of each part are fully fastened and tightened.
(4) when it is put into use, cool flow is first thrown, followed by heat flow.
(5) when using cold medium or hot medium, first ensure the secondary line is unblocked, and then slowly open the outlet valve. After checking no problems, open the inlet valve slowly to prevent the pressure. Attention should be paid to the change of equipment during operation. After the cooler is put into use, leakage may occur as the temperature pressure changes, so it should be checked in time.
