Embodiment Construction

[0046] The present invention will be further described below in conjunction with accompanying drawing.

[0047] The invention discloses a double-acting piston-type pneumatic pump using a low-pressure air source as an energy source, such as figure 1 and figure 2 As shown, the double-acting piston pneumatic pump is mainly composed of a cylinder assembly 10, a reversing device 20, a lower cylinder assembly 30 and an upper cylinder assembly 40.

[0048] Such as image 3 As shown, the cylinder assembly 10, the lower cylinder assembly 30 and the upper cylinder assembly 40 are located on the same axis, and the upper cylinder 40 assembly and the lower cylinder 30 assembly are symmetrical and constitute exactly the same.

[0049] The cylinder assembly 10 includes:

[0050] Cylinder 15;

[0051] The top cover 11 that is arranged on the top of the cylinder is provided with a top cover vent B on the top cover 11 of the cylinder, and the top cover vent B communicates with the reversin...

Abstract

The invention relates to a double-acting piston pneumatic pump, comprising a cylinder assembly, a hydraulic cylinder assembly and a steering device. The cylinder assembly comprises a cylinder, a top cover, a bottom cover, a double-acting piston and a ventilation component; the steering device comprises a steering valve casing, a plunger rod, a plunger, a steering valve seat, a ventilation plate and a square plunger cover; a plunger cover vent hole on the square plunger cover is connected to a side wall vent hole on a copper bush of a steering valve rod to form an airflow path (i); a spool chamber vent hole on the steering valve casing is connected to a bottom vent hole of the copper bush of the steering valve rod to form an airflow path (j); and the steering of the airflow path which pushes the double-acting piston to move upwards and downwards is achieved by controlling the switching between a communicated state and an isolated state of the airflow path (i) and the airflow path (j) so that the conversion from a pressure energy to a hydraulic energy is achieved. The double-acting piston pneumatic pump has the advantages of simple structure, high volume efficiency and fine environment adaptability.

Description

technical field [0001] The invention relates to a pneumatic pump, in particular to a double-acting piston-type pneumatic pump, which is mainly used in working conditions that require intermittent oil supply or require severe changes in flow and pressure and have high requirements for flow and prohibit the use of electricity. occasions. Background technique [0002] A pneumatic pump is a machine that uses a low-pressure air source as an energy source to transport liquids or pressurize liquids. A pump in a broad sense is a machine that transports fluid or pressurizes it, and also includes some machines that transport gas. The pump transfers the mechanical energy of the prime mover or the energy of other energy sources to the liquid to increase the energy of the liquid. [0003] Pneumatic pumps are widely used in various industries, and various types of pneumatic pumps continue to come out. In the petrochemical industry, due to the wide use of high-pressure and ultra-high-pr...
