• On-site leakage treatment steps of gas holder

  The gas holder is one of the very large gas storage tanks. It is welded from steel and widely used for the storage of chemical gas and city gas. It is divided into dry gas holdersCompared with the wet gas holder, the dry gas holder is used to stabilize and adjust the output pressure by the lifting and lowering of the internal large area piston. The installation accuracy and component processing accuracy are relatively high, and the construction difficulty is greater than that of the wet gas holder, but the floor area is relatively small, the storage pressure is high, the stability ratio is good, the service life is long, and the steel is relatively less polluting the environment.The gas holder is the most vulnerable to leakage crisis in long-term operation, and the repair is also very troublesome. Let's take an example first:30000 m for an enterprise ³ The gas holder stores the converter gas, and the sealing form is rubber membrane; Nominal volume: 30000 m ³； Working pressure: ...

• Briefly describe several advantages of double-membrane gas holder

  The double-film gas holder is made of polyester material, which has excellent performance and is widely used. It belongs to excellent engineering and construction plastics. Double-membrane gas fixers are mostly built in open areas. Although the new dual-membrane gas holder is now gas-tight, for the sake of avoiding gas leakage near residents. The gases stored inside include biogas, oxygen, carbon dioxide and other gases. High performance, strong sealing, the outer layer of civil insulating flame retardant materials has strong fire resistance, and also has a certain anti-corrosion ability. Double-membrane gas storage tank has these advantages. Why don't you choose it?1. Higher coefficient Xi'an gas holder priceThe gas storage tank is reliable, with a service life of more than 5 years and low geographical restrictions. It can be used in the weather. The double-layer membrane gas holder is equipped with an overpressure valve and a methane leakage alarm. At the same time, the gas s...

• Necessity of timely maintenance of gas tank (II)

  The key part of the dry gas holder is the piston sealing device. Because the gas is flammable, explosive and toxic, the reliable operation of the thin oil sealing system is related to the safe handling of the gas in the gas holder, the safety of operators, and the environmental pollution caused by the deteriorated sealing oil.(1) The piston oil groove sealing device is subject to standardized construction by professional technical personnel, especially the sealing treatment of sliding plate and column, corner sliding plate, to ensure the construction quality.(2) Adjust and update the sealing mechanism elements. After stopping production for maintenance, it was found that more than 200 of the more than 500 compression springs on some sliding plates were stuck and the spring sleeve did not move; Some bolts originally welded on the sliding plate and piston to fix the spring were broken, and more than 20 springs fell off, resulting in an increase in the clearance between the sliding plate ...

• Necessity of timely maintenance of gas tank (I)

  The maintenance of equipment is divided into preventive maintenance and predictive maintenance: preventive maintenance refers to scheduled and regular equipment maintenance and parts replacement, usually including maintenance, regular use inspection, regular function testing, regular disassembly and repair, regular replacement and other types; Predictive maintenance is to collect data and signals, analyze and judge the deterioration trend, fault location and cause of equipment, predict the change and development, propose preventive measures, and prevent and control the occurrence of possible faults by using various means and human feelings.The sealing of the gas holder is carried out by using the balance of the air pressure and the flow under the sealing oil is controlled by the sliding plate. The oil level of piston oil groove and bottom oil groove is maintained through the circulation of seal oil, so that the gas tank can operate stably.Problems and causes of gas holder sealing:(1) T...

• Daily maintenance of thin oil sealed dry gas holder must be done

  Maintenance of sealing mechanismThe sealing mechanism is an important component in the safe and reliable operation of the thin oil sealed dry gas holder, and its operation condition directly affects the operation of the gas holder.The main aspects of daily maintenance are as follows:(1) Compression springThe sliding plate is closely connected with the side plate of the gas holder through the spring. As the gas holder piston moves up and down, the compression spring is always in the state of expansion and compression, and its elasticity decreases over time. In addition, affected by the surrounding environment of the gas holder, the dust in the air will enter the gas holder and attach to the side plate, and some of it will be scraped into the piston oil groove, and deposited in the canvas pocket to form oil dirt, In serious cases, the oil dirt will enter the spring sleeve and block the spring action, resulting in the failure of the sealing mechanism and a large amount of leakage of the s...

• Maintenance problems of thin oil dry seal gas holder

  As an important facility for storing gas, the thin oil sealed dry gas holder was widely used in oil refining enterprises in the 1990s. Its working principle is to maintain the oil level of the gas holder piston and seal the gas in the tank by relying on the intermittent start and stop of the circulating oil pump. Because of its simple operation, flexibility, stable pressure (adjustable 3.00~10.00 KPa), it has played a huge role in the gas balance process of Sinopec refining and chemical enterprises. In recent years, due to the increase of the sulfur content in the gas, the corrosion problem of the equipment has become increasingly prominent. Some problems have generally occurred in the gas tank put into use in the above period, such as corrosion and perforation of the oil groove at the bottom of the tank, the bottom plate of the oil-water separator, the perforation of the diaphragm, and the failure of the piston sealing slider, which seriously threaten the safe production of the gas ta...
