Hydraulic Jack Essay

DESIGN, DEVELOPMENT AND TESTING OF NOVEL REMOTE CONTROLLED ELECTRICALLY OPERATED HYDRAULIC JACK

ABSTRACT

Now a days, people have a penchant for luxury, comfort and safety in each and every aspect of their lives provided money and technology available with the mankind. This project aims towards reducing the physical effort by humans to lift an automobile by automating the Hydraulic Jack through coupling it with a wiper motor and a radio frequency (RF) module. It works on the mechanism of conversion of rotatory motion of the wiper motor into the reciprocating motion of the hydraulic jack?s plunger. The functioning of the motor being controlled by the RF module and a remote, through simple push of a button one could lift a heavy vehicle thereby reducing the physical effort considerably. A prototype illustrating the aforementioned mechanism was designed and fabricated. Also, it was tested and its functioning can be successfully illustrated.

INTRODUCTION

In

The crank of the four bar link is connected to the motor and the rocker acts as the hydraulic jack plunger. When the crank is being rotated by the motor, the rocker or the jack plunger reciprocates. The plunger is first drawn back, which opens the suction valve ball within the hydraulic jack and draws oil into the pump chamber. As the plunger is pushed forward, the oil moves through an external discharge check valve into the cylinder chamber, and the suction valve closes, which results in pressure building within the cylinder. However, because one cylinder has larger area compared to other, the force produced by the larger cylinder is higher, although the pressure in the two cylinders remains the same allowing the jack to lift hefty
