A double plunger supercharger

Abstract

The invention discloses a double-plunger supercharger, which comprises a machine body, a mounting hole is arranged in the body, a P port and a T port communicated with the mounting hole are arranged on the side of the body; the left side of the body is installed There is a left end cover, and a right end cover is installed on the right side; the left end cover includes a left body, the left body is provided with a left post, and the right end of the left post is provided with a left two post; the right end cover includes a right body, a right The body is provided with a right convex column, and the left end of the right convex column is provided with a right two convex column; a cylinder liner is slidably connected in the installation hole; a power piston is slidably connected in the cylinder liner; A left piston chamber is formed between the left end of the power piston and the two left convex posts, and a right piston chamber is formed between the right end of the power piston and the two right convex posts; Pump assembly; the double plunger supercharger is not only highly integrated in overall design, saving space and parts, but also reduces oil passages, simple control, and no need for electric control.

Description

technical field [0001] The invention belongs to the technical field of superchargers, and in particular relates to a four-piston supercharger. Background technique [0002] The superchargers currently used in the market are mainly traditional single-plunger superchargers and double-plunger reciprocating superchargers. The single-plunger supercharger cannot guarantee the continuity of the pressure output, and cannot meet many high-pressure work requirements. Although the double-plunger reciprocating supercharger can achieve continuous pressure output, the output pressure is zero at the moment of reversing, making the output The high pressure produces pulsation, which cannot be used in some occasions that require constant pressure; although there are dual-cylinder four-piston superchargers on the market, such as a four-piston hydraulic supercharger with application number 201810417249.0, it is used to control The first pressurized cylinder and the second pressurized cylinder ...

The single-plunger supercharger cannot guarantee the continuity of the pressure output, and cannot meet many high-pressure work requirements. Although the double-plunger reciprocating supercharger can achieve continuous pressure output, the output pressure is zero at the moment of reversing, making the output The high pressure produces pulsation, which cannot be used in some occasions that require constant pressure; although there are dual-cylinder four-piston superchargers on the market, such as a four-piston hydraulic supercharger with application number 201810417249.0, it is used to control The first pressurized cylinder and the second pressurized cylinder operate continuously, using the way that two pistons control the direction of each other’s oil passages. The oil passages involved are complicated, the control is complicated, the structure is complicated, the volume is large, and the cost is high; and because of its The control is complicated and the oil circuit is complicated. When a fault occurs, it is not only difficult to troubleshoot the problem, but also inconvenient to maintain
