Description

The present invention relates to a structure that integrates a split piston of a linear motion type plunger pump, and attaches a flywheel cover to a flywheel attached to a camshaft to increase permanent rotation, thereby stabilizing the piston reciprocation of the plunger pump at high speed.

Conventionally, the plunger pump has a piston reciprocating motion with a crank rotation structure, large torque fluctuation, low speed rotation, high noise / vibration, and low efficiency.
Japanese Patent Application No. 2007-292572 (assessed on September 2, 2008) filed by the present applicant for solving this problem is an existing technology.

In order to solve the above problem, the piston and the piston rod that drive the reciprocating stroke at high speed are integrated, and a flywheel with a cover is provided to increase the output.

In order to solve the above problems, the present invention divides the piston reciprocating in the pump cylinder into two parts, combines and integrates a plurality of divided seal rings and slide rings, and attaches and stabilizes a flywheel cover that rotates following the flywheel. The reciprocating motion is carried out with the rotated rotation.

The present invention is a linear motion plunger pump, which reduces energy used for generating compressed air and contributes to environmental and resource protection.

Claims (2)

The piston of the linear motion type plunger pump is divided into two parts, and one of the divided pistons is connected to the end of the piston rod, the divided type bottom piston and others are divided into divided type top pistons. A plurality of slide rings and seal rings with different shapes are built in between, and these combinations are much more slidable and confidential when compressed by air at room temperature than conventional slide rings and seal rings. With improved lubrication, no lubrication, improved durability and reciprocation, weight reduction, and a structure that pushes this piston unit into the cylinder to improve continuous high-speed reciprocation. In order to efficiently move the linear motion plunger pump back and forth stably and at high speed, the flywheel provided on the cam drive shaft reduces the cam rotation unevenness and increases the silent continuous rotation torque. A plurality of flywheel covers are attached, and flywheel cover bearings are provided on the camshaft while following the rotation of the flywheel. Each flywheel cover is set on the outer periphery of the cover bearing and is individually rotated with a thrust washer. A structure that increases the rotational torque by reducing the air resistance inside the cover wheel by rotating the flywheel with a cover that rotates and revolves without interference.
