Capillary refers to a tube with a very small inner diameter. In an industrial chiller system, a capillary refers to a copper tube within 1-2 mm. What is the role of the capillary in the chiller?

The metal capillary tube is one of the throttling devices of the chiller. The role of the capillary in the chiller is to throttle. The principle is simple, in order to increase the "flow resistance of the liquid flowing through the capillary". The ultimate goal is to control the amount of liquid supplied. However, while increasing the resistance to liquid flow and controlling the amount of liquid supplied, the capillary also has a depressurizing effect. When the high pressure refrigerant flows through the capillary, it changes from a high pressure liquid to a low-pressure high-temperature gas.

Specifically, the inner diameter and total length of the chiller throttling capillary and the nominal pressure difference between the inlet and outlet are all factors influencing the chiller throttling capillary. However, specific calculations require integrated cooling temperatures as well as evaporation temperatures, evaporation pressures, and the like. The evaporation pressure should be the same as the capillary outlet pressure.

By obtaining the pressure difference between the inlet and outlet, it is possible to obtain the values of the inner diameter and the length of the capillary, and then select the corresponding capillary. In most cases, this calculation does not have a fixed value, and the experimental values obtained by each chiller manufacturer may be different and complicated.

The capillary can adjust the amount of liquid supplied as well as throttling and depressurization. However, before the chiller leaves the factory, the length and inner diameter of the capillary should be determined and configured, rather than the customer's own calculation and installation, so the customer does not have to worry. However, when the first actual use and trial operation of the machine, it can also be slightly adjusted to meet the actual needs.

In addition, the stainless steel capillary tube is mainly used in a small chiller system with a small cooling capacity. The selected capillary has a small inner diameter and a long length, and the flow rate of the refrigerant flowing through the capillary is naturally small and the pressure is lower. The opposite is true. The value of the capillary inner diameter (diameter) and the length are determined according to the actual needs of the chiller.

Most of the chillers with large cooling capacity use expansion valves as throttling devices, and the expansion valves are installed between the refrigerant tank and the evaporator to throttle and reduce the pressure. The expansion valve allows the refrigerant that has been returned to the chiller system and has a relatively high temperature and relatively high pressure to become a low-temperature low-pressure refrigerant vapor through the expansion valve, and then enters the evaporator to absorb heat to achieve a cooling effect.

Stainless steel round tube is a hollow strip of round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial conveying pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Stainless steel round tube is also commonly used to produce a variety of conventional weapons, barrels, shells and so on.

Classification

Such steel tubes can be divided into two categories: stainless steel seamless steel tubes and stainless steel welded steel tubes (with seam tubes).According to the manufacturing process, there are several basic types of hot rolling, extrusion, cold drawing and cold rolling. According to the shape of the section, it can be divided into a circular tube and a special-shaped tube. A circular steel pipe is widely used, but there are also some square, rectangular, semi-circular, hexagonal, equilateral triangle, octagonal and other shaped stainless steel pipe.

For steel tubes subjected to fluid pressure, hydraulic tests are carried out to verify their pressure resistance and quality. No leakage, wetting or expansion is allowed to pass under the specified pressure. Some steel tubes are also subjected to crimping test, flare test and flattening test according to the standard or the requirements of the purchaser.

Seamless stainless steel round tube, also called stainless steel seamless tube, is made of steel ingot or solid tube blank through perforation, and then made by hot rolling, cold rolling or cold drawing. The specifications of the seamless steel pipe are expressed by the outer diameter by the wall thickness in millimeters.

The 304 stainless steel round tube is called SUS304 stainless steel tube, and the SUS304 stainless steel round tube is a stainless steel tube of American grade material. The domestic grade is equivalent to 0Cr19Ni9 stainless steel tube, usually replaced by 0Cr18Ni9. The mechanism of stainless steel rust prevention is that the alloying elements form a dense oxide film, which is insulated from oxygen and prevents further oxidation. Therefore, stainless steel is not "stainless".

Use of stainless steel tube

It is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures.

How do we properly operate the steel bar straightening and cutting machine in daily life?

First of all: When operating the wire straightening theory and cutting machine, select the appropriate straightening die according to the diameter of the wire to be straightened, the diameter of the straightening die should be 2~3mm bigger than the diameter of the wire to be straightened. The head and the tail straightening dies must be placed on the centerline of the straightening cylinder, the middle three can be off the centerline. Generally, we let the wire has a displacement of 3 ram. After the straightening test, if the wire still can be observed with a slow bending phenomenon, it will be corrected by gradually adjusting the offset until the wire can be straightened out.

Second point: In order to ensure the safety and quality of the reinforcing bar straightening operation, the rebar straightening and cutting machine  should be installed on a solid concrete foundation, and the machine shed should be set up in the outdoor work. There should be enough space for piling up materials and semi-finished products next to the machine shed site. The third point: the bearing frame groove should be installed straight, and its center should be aligned with the center line of the guiding cylinder, the straightening cylinder and the lower cutting hole. The wire turntable mounting should be installed at a distance of 5 to 8 m from the straightening machine.

Fourth point: Before the official start of operation, the wire straightening and cutting machine should run idle motion for 2 hours, then check the temperature of the bearing and whether the hammer head, cutter or cutting gear is working properly. After confirming that there is no abnormal condition, the machine an be fed and tested for straightening and cutting ability.

Fifth point: The newly installed wire straightening and cutting machine should be checked whether the electrical system and components are damaged, whether the connection and joints of each components are firm and reliable, whether the rotating parts are flexible, and whether the performance of the transmission and control system meets the requirements. We can only run the test operation after all the above aspects are ensured to meet the requirements.

Sixth point: The fixed cutter should be adjusted appropriately according to the position of the movable cutter. The gap between the upper and lower cutters should be no more than 1mm wire. Some preparatory work should be done to ensure the side gap be no more than 0.10~0.15mm before the cut and bend steel machine is processed.

Because of the bad working environment, hull to corrosion by seawater chemical corrosion, electrochemical corrosion and marine organisms and microorganisms; hull under high wave and alternating load; the ship shape processing method of complex factors such as, so the steel hull structure strict requirements. First of all, good toughness is the most critical requirement. Besides, it requires high strength, good corrosion resistance, welding performance, processing performance and surface quality. In order to ensure quality and ensure enough toughness, the chemical composition of Mn/C is above 2.5, and the carbon equivalent is also strictly required, and it is produced by a steel factory approved by the ship inspection department. The strength grade of the structural steel used in the hull is divided into the general strength structural steel and the high strength structural steel according to the minimum yield point. Hull structural steel is divided into two kinds: general strength and high strength steel. The general strength steel is divided into four grades according to the quality: A, B, D and E. The high-strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36 and EH36.

The standard strength steel of China Classification Society is divided into four quality grades: A, B, C and D, namely, CCSA, CCSB, CCSC and CCSD. The high strength structural steel regulated by China Classification Society is three strength grade and four quality grade.
