Description

Technical Field

[0001] The utility model relates to the technical field of blower compressors, in particular to a Roots blower compressor for a gas gathering station. Background Art

[0002] With the rapid development of the global economy and the continuous growth of the population, the demand for energy continues to rise. Natural gas, as a clean, efficient, and environmentally friendly energy source, is gaining favor in an increasing number of countries and regions. For example, in the industrial sector, natural gas can be used for power generation and chemical production; in the civilian sector, it is an important source of gas for residential use. This increasing demand for natural gas has driven the development of related industries such as natural gas extraction and transportation, and has also provided a broad market for the application of Roots blowers and compressors in gas gathering stations.

[0003] In the existing technology, the traditional Roots blower compressor of the gas gathering station will produce high vibration due to the influence of intake and exhaust pulsation and backflow impact. Long-term high vibration will lead to aggravated rotor imbalance, severe local wear of the rotor blades, and even excessive accumulation of coke and oil. This not only affects the normal operation of the rotor, but may also cause serious faults such as rotor cracking, which in turn causes the entire blower to fail to work normally. The vibration will generate additional load and impact on the bearings, accelerate bearing wear, and shorten their service life. Once the bearings are damaged, the operating stability of the blower will be greatly affected, and in severe cases, the blower may be caused to shut down. High vibration will cause uneven pressure and friction on the seals, which may easily cause the seals to deform, age or be damaged, resulting in gas leakage, affecting the production efficiency and safety of the gas gathering station. Faults such as cracking of the blower casing, cover plate and rotor are often caused by excessive vibration. Damage to these structural parts will not only increase maintenance costs, but also affect the normal operation of the blower. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a Roots blower compressor for a gas gathering station.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a Roots blower compressor for a gas gathering station, comprising a support platform and a base plate, a blower platform is fixed on the upper end of the support platform, a power box is fixed on the upper end of the support platform, a ventilation plate is fixed inside the support platform, a through hole is opened inside the ventilation plate, a connecting spring is fixed inside the ventilation plate, a sealing ball is fixed at the bottom of the connecting spring, a movable base is fixed on the surface of the ventilation plate, a piston base is slidably connected to the inside of the movable base, a damping lifting and retraction rod is fixed on the surface of the piston base, the upper end of the damping lifting and retraction rod is fixed to the surface of the movable base, a support spring is fixed on the surface of the piston base, and the upper end of the support spring is fixed to the bottom of the movable base.

[0006] Preferably, a connecting pipe is fixed to the top of the blower platform, a sealing nut is threadedly connected to the inside of the connecting pipe, and an air pipe is rotatably connected to the inside of the sealing nut. A sealing spring is sleeved on the surface of the air pipe, and sealing plugs are fixed to both ends of the sealing spring. A fixing nut is rotatably connected to the bottom of the air pipe, and a gas pipe is threadedly connected to the surface of the fixing nut. The bottom of the gas pipe is connected to the blower platform. In the prior art, the air pipe of the Roots blower compressor in a traditional gas gathering station cannot be rotated to adjust the direction. In the actual operation of the gas gathering station, different production conditions may have different gas flow direction and flow rate requirements. If the air pipe cannot be rotated to adjust the direction, it cannot be flexibly adjusted when the gas flow direction needs to be changed to adapt to different operating conditions, resulting in obstructed gas flow, reduced gas transmission efficiency, and unnecessary bends, turns, or turbulence in the air flow within the pipe, thereby increasing pressure loss in the pipe. This not only consumes more energy to overcome this additional resistance, but also reduces the efficiency of the entire compression system. It may cause significant inconvenience when maintaining and repairing the Roots blower compressor or other related equipment. For example, when replacing certain parts or conducting internal inspections, it may be necessary to adjust the position of the air pipe to obtain a better operating space, but if the air pipe cannot be rotated, the difficulty and time of the operation will increase. In addition, for some large gas gathering station equipment, if the direction of the air pipe cannot be flexibly adjusted, it may also affect the transportation and installation of the equipment, and increase the difficulty and cost of project implementation. To address such problems, the utility model uses a new type of pipeline device. When the staff needs to change the direction of the fan pipeline, the user rotates the air pipe of the fan. Because the bottom of the air pipe and the ventilation pipe can rotate with each other, the sealing spring pushes the sealing plug at one end to make the sealing plug close to one end of the connecting pipe. At the same time, the other end is sealed to the other end of the connecting pipe due to the elastic force of the sealing spring, further reducing the escape of gas, thereby increasing the air pipe rotation ability of the Roots blower compressor, improving its applicability, and the convenience of maintaining the facilities.

[0007] Preferably, a fan base is fixed to the bottom of the fan platform, a bolt is threadedly connected to the surface of the support platform, an elastic sheet is slidably connected to the surface of the bolt, and a connecting nut is threadedly connected to the upper end of the bolt. During the operation of the fan, vibration will be generated. If the bolt is directly connected to the support platform, without the buffering effect of the elastic sheet, the vibration will be directly transmitted to the connection between the bolt and the nut, which may cause the connecting nut to loosen or even fall off. The addition of the elastic sheet can absorb some of the vibration energy and reduce the impact of vibration on the connection part, thereby making the equipment more stable as a whole and reducing the risk of nut falling off due to vibration.

[0008] Preferably, a degassing groove is provided on the surface of the movable base, thereby further increasing the gas release speed of the shock-absorbing structure, thereby increasing its compression speed, and further increasing its energy conversion speed.

[0009] Preferably, the support spring is a double-strand spring, which has excellent energy storage and release capabilities. The double-helix structure allows the use of a larger number of coils, which means a higher energy storage capacity, ensuring the smooth operation of the system and reducing the risk of mechanical failure.

[0010] Preferably, an air gasket is fixed to the surface of the sealing plug. This gasket exhibits good elasticity and can better adapt to changes in the shape and size of the sealing surface. In complex operating environments such as gas gathering stations, pipes and equipment may experience slight deformation or displacement due to factors such as temperature and pressure. The air gasket can fill these gaps through its own elastic deformation, thereby maintaining sealing performance and preventing gas leakage. The combination of the air gasket and the sealing plug increases the contact area of ​​the seal, making the seal more reliable. Compared with sealing structures without air gaskets, air gaskets can provide more uniform sealing pressure and reduce the possibility of leakage.

[0011] Preferably, an angle iron is fixed to the upper end of the fan base. The angle iron can increase the rigidity and stability of the base and prevent the fan from vibrating or displacing during operation. The angle iron can disperse and bear the weight of the fan, thereby improving the bearing capacity of the entire structure.

[0012] Beneficial effects

[0013] 1. In the existing technology, the Roots blower compressor of the traditional gas gathering station will produce high vibration due to the influence of intake and exhaust pulsation and backflow impact. Long-term high vibration will lead to aggravated rotor imbalance, severe local wear of the rotor blades, and even excessive accumulation of coke and oil. This not only affects the normal operation of the rotor, but may also cause serious faults such as rotor cracking, which will lead to the whole blower not being able to work properly. The vibration will generate additional load and impact on the bearings, accelerate the wear of the bearings, and shorten their service life. Once the bearings are damaged, the operational stability of the blower will be greatly affected, and in severe cases it may cause the blower to shut down. High vibration will cause uneven pressure and friction on the seals, which may easily lead to deformation, aging or damage of the seals, resulting in gas leakage, affecting the production efficiency and safety of the gas gathering station. Faults such as cracking of the blower casing, cover plate and rotor are also common. It is caused by excessive vibration. The damage of these structural parts will not only increase the maintenance cost, but also affect the normal operation of the fan. To solve this problem, the utility model uses a new shock-absorbing device. When the device vibrates, the impact force generated squeezes the movable base to move downward, thereby causing the piston base to squeeze the internal gas to move upward. After the gas inside the movable base is squeezed through the sealing ball, it is discharged with the help of the grooves on the surface of the vent plate. At the same time, part of the kinetic energy generated by the impact is converted into potential energy of the supporting spring and the internal energy inside the damping telescopic rod through the support spring for storage and consumption. During rebound, the connecting spring squeezes the sealing ball downward to reduce the airflow backflow rate and reduce the speed of mechanical movement rebound, thereby reducing the damage of the Roots blower compressor to vibration, thereby improving its seismic performance and ensuring that it can work stably and reliably in various environments.

[0014] 2. In the existing technology, the air pipe of the Roots blower compressor in the traditional gas gathering station cannot be rotated to adjust the direction. In the actual operation of the gas gathering station, different production conditions may have different requirements for the flow direction and flow rate of the gas. If the air pipe cannot be rotated to adjust the direction, then when the gas flow direction needs to be changed to adapt to different working conditions, it cannot be flexibly adjusted, resulting in obstruction of gas flow, reducing the gas transmission efficiency, and causing unnecessary bends, turns or turbulence in the air flow in the pipeline, thereby increasing the pressure loss of the pipeline. This will not only consume more energy to overcome these additional resistances, but also reduce the efficiency of the entire compression system, which may cause great inconvenience to the operation when maintaining and repairing the Roots blower compressor or other related equipment. For example, when replacing certain parts or conducting internal inspections, it may be necessary to adjust the position of the air pipe to obtain a better operating space, but if the air pipe cannot be rotated, the difficulty and time of the operation will increase. In addition, for some large gas gathering station equipment, if the direction of the air pipe cannot be flexibly adjusted, it may also affect the transportation and installation of the equipment, and increase the difficulty and cost of project implementation. To address such problems, the utility model uses a new type of pipeline device. When the staff needs to change the direction of the fan pipeline, the user rotates the air pipe of the fan. Because the bottom of the air pipe and the ventilation pipe can rotate with each other, the sealing spring pushes the sealing plug at one end to make the sealing plug close to one end of the connecting pipe. At the same time, the other end is sealed to the other end of the connecting pipe due to the elastic force of the sealing spring, further reducing the escape of gas, thereby increasing the air pipe rotation ability of the Roots blower compressor, improving its applicability, and the convenience of maintaining the facilities.

In the prior art, the traditional Roots blower compressor of the gas gathering station will produce high vibration due to the influence of the intake and exhaust pulsation and the backflow impact.

Once the bearings are damaged, The operational stability of the fan will be greatly affected, and in severe cases it may cause the fan to shut down. High vibrations will subject the seals to uneven pressure and friction, which can easily lead to deformation, aging or damage of the seals, resulting in gas leakage, affecting the production efficiency and safety of the gas gathering station.

At the same time, part of the kinetic energy generated by the impact is converted into potential energy of the supporting spring 206 and the internal energy inside the damping telescopic rod for storage and consumption. Later, when rebounding, the connecting spring 201 squeezes the sealing ball 202 downward to reduce the air flow backflow rate and the speed of mechanical movement rebound, thereby reducing the damage of vibration to the Roots blower compressor, thereby improving its seismic performance and ensuring that it can work stably and reliably in various environments.
