The main difference between a hydraulic lubrication pump and a lubrication pump

What is a hydraulic lubrication pump?

Hydraulic lubrication pump is a piston lubrication pump using hydraulic power, using double cylinder double plunger symmetrical structure, equipped with explosion-proof electromagnetic directional valve, can realize a drive oil pipe access, electromagnetic directional valve reversing drive double cylinder motion pumping grease. Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic pumps or hydropower pumps. The hydraulic pump is a mechanical power source, which converts mechanical power into hydraulic energy. The flow it produces has enough power to overcome the pressure caused by the load at the pump outlet. When the hydraulic pump works, it creates a vacuum at the inlet of the pump, forcing the liquid from the reservoir into the inlet line of the pump, and transporting these liquids to the outlet of the pump by mechanical action, forcing it into the hydraulic system. The hydrostatic pump is a positive displacement pump, while the hydraulic pump can be a fixed displacement pump, the displacement cannot be adjusted, or it can be a variable displacement pump, its structure is more complex, and the displacement can be adjusted.

The main differences between hydraulic pumps and lubrication pumps:

1. Different in nature. The hydraulic pump is the power component of the hydraulic system, which is driven by the engine or electric motor, sucks oil from the hydraulic tank, forms a pressure oil discharge, and sends it to the actuator. A lubrication pump is a kind of lubrication equipment that supplies lubricant to the lubricated part.

2. The function is different. The hydraulic pump converts the mechanical energy of the power pump into the pressure energy of the liquid. The lubrication pump is to supply lubricant to the lubrication part, reduce equipment failure and extend the service life of the machine.

3. Different characteristics. The hydraulic pump is made of aluminum alloy, high strength, corrosion resistance, light weight, suitable for various environments. The lubrication pump is fuel-efficient, pollution-free and maintenance-free.

How does a hydraulic lubrication pump work?

The cam is driven by an electric motor to rotate. When the cam pushes the plunger upward, the sealing volume formed by the plunger and the cylinder block is reduced, and the oil is squeezed out of the sealing volume and discharged to the place where it is needed through the check valve. When the cam rotates to the descending part of the curve, the spring forces the plunger downward, forming a certain vacuum degree, and the oil in the tank enters the sealing volume under the action of atmospheric pressure. The cam makes the plunger continuously rise and fall, the sealing volume periodically decreases and increases, and the pump continuously absorbs and drains oil.
