High Pressure Hand Manual Operated Pressure Oil Pump
hand manual pressure pump
As a simple and convenient hydraulic power source, ultra-high pressure hand operated oil pump is widely used in many fields, such as ship industry, coal mine machinery, petrochemical, metallurgy, electric power and heavy machinery. It is small in volume and light in weight. Easy to carry, strong security and other advantages are accepted by the majority of users.
The function of a manual hydraulic pump is to convert the mechanical energy of a power engine (such as a motor and an internal combustion engine) into the pressure energy of a liquid.
Working principle: The cam is rotated by the motor. When the cam pushes the plunger upward, the seal volume formed by the plunger and cylinder block decreases, and the oil is extruded from the seal volume. When the cam rotates to the descending part of the curve, the spring forces the plunger down to form a certain vacuum. The oil in the tank enters the sealing volume under the action of atmospheric pressure. The cam causes the plunger to rise and fall continuously, the seal volume decreases and increases periodically, and the pump continuously absorbs and drains oil.
