Description

Technical Field

[0001] The invention belongs to the technical field of booster pump equipment, and in particular relates to a pneumatic liquid-adding automatic proportioning pump and a use method thereof. Background Art

[0002] In many fields such as tunnels, mining, lanes, and machining, it is often necessary to use a hydraulic system as a power source to drive the equipment to operate. However, in actual use, the current hydraulic system often uses an electric motor to drive a booster pump and related circuit equipment to assist in driving to pressurize the hydraulic oil and then drive the equipment to operate. Although it can meet the needs of use, on the one hand, the structure of the motor-driven booster pump system is relatively complex and large in size, so the flexibility, convenience, and site adaptability of use are relatively poor. On the other hand, the motor and the motor-assisted circuit system are prone to produce electric sparks, static electricity, leakage, etc. during operation. Therefore, the current motor-driven hydraulic system has poor safety when operating in a flammable and explosive environment and cannot effectively meet the needs of use, further limiting the flexibility, convenience, and safety of the current hydraulic system. To address this problem, a pneumatic pump driven by high-pressure gas has also been developed. Although it can also meet the needs of boosting the hydraulic fluid, the pneumatic pump is large in size, has high operating noise and vibration, and on the other hand, during the boosting operation, the boosting efficiency and pressure control accuracy are poor, making it difficult to effectively meet the needs of efficient boosting operations.

[0003] In addition, currently, whether it is a booster pump driven by an electric motor or a booster pump driven by high-pressure gas, it is impossible to achieve an accurate ratio of two different liquid materials during the process of pressurizing the hydraulic oil, resulting in the inability to effectively and flexibly mix the hydraulic fluid with auxiliary materials such as modifiers during use. As a result, the hydraulic fluid is prone to deterioration during use, and there is serious wear between the hydraulic fluid and the pipeline, which seriously affects the stability and reliability of the hydraulic system operation. At the same time, it also causes the service life of the hydraulic fluid to be relatively short.

[0004] Therefore, in view of this situation, it is necessary to develop a new booster pump and a method of use to meet the needs of actual use. Summary of the invention
