Ventilation booster pump

Abstract

The invention belongs to the technology of a booster pump, and relates to a ventilation booster pump. The ventilation booster pump consists of two groups of air cylinders, two-position valves and rigid piston assemblies, wherein the rigid piston assemblies are arranged inside the two groups of air cylinders, and two ends of each air cylinder are respectively provided with a left two-position valve and a right two-position valve, which are used for the reversing control. Each group of air cylinders consists of a right small air cylinder, a right large air cylinder, a left small air cylinder and a left large air cylinder, wherein the left small air cylinder is connected with the left large air cylinder, the left large air cylinder is connected with the right large air cylinder, an air cylinder sealing pad is arranged between the left large air cylinder and the right large air cylinder, and the right large air cylinder is connected with the right small air cylinder. Through the combination design of four air cylinders, the continuous supercharging air supply can be realized and the supercharging efficiency can be increased; and moreover, the tail gas can be adequately utilized, so that higher air-pressure flow can be obtained. In addition, by changing the proportional size of the air cylinder, the appropriate high-pressure airflow can be supplied for a high-pressure air consumption device, so that wider application range can be realized.

Description

technical field [0001] The invention belongs to booster pump technology and relates to a ventilation booster pump. technical background [0002] The working principle of the existing domestic traditional booster pump is to release energy through fuel combustion, convert it into the required mechanical energy, and generate high-pressure airflow. [0003] The traditional pressure pump mainly has the following problems during use: [0004] 1) Gas utilization problem [0005] The high-pressure flow generated by the traditional booster pump is generated by using the energy provided by the combustion of fuel to drive the low-pressure gas at the piston end with a large area. This process does not make full use of the exhaust gas after fuel combustion, and the energy conversion efficiency is low. Therefore, in order to meet the requirements of higher high-voltage equipment, more energy needs to be consumed, so the energy consumption of the whole process is very large. [0006] 2...

AI Technical Summary

Problems solved by technology

[0007] The high-pressure gas generated by the traditional booster pump sometimes cannot fully meet the needs of high-pressure equipment. Simply put, the fuel tank of the booster pump has a certain amount of fuel, so after a certain amount of fuel is burned, the high-pressure gas generated There are also certain restrictions. When the demand for high-pressure equipment cannot be met, more fuel oil needs to be burned to provide a higher gas flow. In this way, for some gas-consuming equipment that requires more compressed air flow, the traditional booster The range of application of the pressure pump is limited
