Application and Maintenance of DK800-6 Rotameter Meter in Hyperbaric Oxygen Chamber

Abstract: The application and maintenance information of DK800-6 rotor flowmeter in hyperbaric oxygen chamber is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. In hyperbaric oxygen therapy, placing the body in a high-pressure environment in a hyperbaric oxygen chamber, allowing the patient to breathe pure oxygen at the same pressure as the environment, are two important aspects of hyperbaric oxygen therapy in an air pressurized chamber. Whether the patient can effectively absorb oxygen in a hyperbaric environment is hyperbaric oxygen therapy. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the application and maintenance article details of DK800-6 rotor flowmeter in hyperbaric oxygen chamber. In hyperbaric oxygen therapy, placing the body in a high-pressure environment in a hyperbaric oxygen chamber, allowing the patient to breathe pure oxygen at the same pressure as the environment, are two important aspects of hyperbaric oxygen therapy in an air pressurized chamber. Whether patients can effectively absorb oxygen in a hyperbaric environment is the core link of hyperbaric oxygen therapy. The application of the DK800-6 rotameter objectively guarantees the intuitive observation of whether the patient is taking oxygen effectively. Aiming at the two different oxygen supply methods of pulmonary oxygen supply (on-demand oxygen supply) and continuous oxygen supply, the DK800-6 rotor flowmeter plays a qualitative and quantitative indication role respectively. Ground repairs are also worth exploring. 1 Clinical application of DK800-6 rotameter With the continuous expansion of the application field of hyperbaric oxygen therapy and the transformation and innovation of oxygen inhalation terminals, the oxygen supply method has also developed from the original single lung oxygen supply to lung oxygen supply and continuous oxygen supply. Two kinds of oxygen. Therefore, the application of DK800-6 rotameter in clinical also has a new usage. One is the conventional usage, that is, the DK800-6 rotameter is used in pulmonary oxygen supply. This usage can be used for convenient and intuitive qualitative observation on the flowmeter, mainly to observe the effective oxygen inhalation and the instantaneous flow rate of each oxygen inhalation of the patient. Where there is air leakage in the contact part with the mask, the operator uses this observation to guide the patients in the cabin to correct the bad condition in time to ensure effective oxygen inhalation. The second is to expand the usage, that is, the DK800-6 rotor flowmeter is used in continuous oxygen supply. The flowmeter is used as both a switch and a flow regulator, which can quantitatively adjust the flow rate. The operator can adjust the oxygen supply flow rate by observing the size of the oxygen inhalation terminal balloon in the cabin. This usage of the flowmeter can ensure effective suction. Oxygen, but still must pay close attention to the air tightness of the patient's oxygen inhalation terminal to avoid high oxygen concentration in the cabin caused by oxygen leakage. These two uses of the DK800-6 rotor flowmeter solve the oxygen inhalation needs and effective oxygen inhalation problems of various patients, benefiting more patients. 2 Common faults and maintenance of DK800-6 rotor flowmeter The DK800-6 rotor flowmeter has almost no faults in conventional usage, because this usage does not operate the flowmeter and is in static use; while in the extended usage of the flowmeter, it is A kind of dynamic use. During the treatment process, the flowmeter must be operated every time the patient starts and stops oxygen inhalation (rest) and adjusts the oxygen supply flow. In this dynamic use, the flowmeter is easy to come out. Faults, the common faults and maintenance are summarized as follows: 2.1 The DK800-6 rotor flowmeter is not closed tightly. At float, there is a small flow indication visible to the naked eye. The root cause of this failure is that the conical adjusting screw of the flowmeter and the running-in surface of the adjusting seat interface with a sealing ring on the back and a small cylinder with a neck in the center of the front are poorly engaged. Because the joint surface is rigid joint, improper force when switching the knob will easily damage the joint surface of the grinding mouth and cause it to close loosely. During maintenance, zero-size sandpaper can be used on the conical joint surface of the adjusting screw and the neck of the adjusting seat respectively. The circular hole joint surface of the cylinder is polished by the method of rotation. Generally, 30 to 50 turns of rotation can make the joint surface joint well and repair the fault. This method can be repaired about 3 to 4 times. Once the small cylinder of the neck on the adjusting seat is ground flat, the method of grinding with sandpaper can no longer be repaired. In practice, we have used the method of rigid-flexible combination for re-repair and the effect is good. The specific method is: take the rubber tube of the sphygmomanometer cuff (outer diameter 8mm, inner diameter 4mm), cut a section of 5mm, this section of rubber tube can be very Appropriately placed in the rigid fixed sleeve between the adjustment seat and the adjustment screw, this sleeve just has an inner sill of about 3mm, which can make the rubber tube tightly fit on the inner sill, and the protruding part of the rubber tube is about 2mm. When the cap is tightened, it is tightly connected with the adjustment seat. This rubber tube not only acts as a rubber gasket seal, but also changes the original rigid connection between the adjustment seat and the adjustment screw into a rigid-flexible connection, so that the closing is not tight. This innovative maintenance can also improve the switching performance of the flowmeter, the switch is light, and the failure of the flowmeter not closing tightly will not occur for a long time, until the rubber tube is aged and deformed and then replaced.

In the past few decades, vortex flow meter manufacturer production has increased because of the use of mass flow meter.

Deeper connections between Beijing Sincerity Automatic Equipment Co., Ltd and customers can be made when we're thinking out of the box and meeting outside of manufacturing work.

Beijing Sincerity Automatic Equipment Co., Ltd have significantly changed the way customers approach manufacturing. mass flow meter can still compete if we are willing to change the ways in producing.

Making a few technical tweaks to the way you structure and distribute mass flow meter could be the difference between an engaging, thought-provoking product and a perfunctory one.
