An oil-air lubrication system with pulsed oil injection

technical field

The utility model relates to a lubricating system, in particular to an oil-air lubricating system for pulsed oil injection.

Background technique

Oil-air lubrication is a new type of lubrication technology, which is suitable for the latest development of machinery and industrial equipment, especially suitable for high temperature, heavy load, high speed and harsh working conditions with cooling water and dirt intruding into the lubricating point.

The oil-air lubrication system mainly includes an oil supply part, an air supply part and an oil-air mixing part. Among them, the main station of the oil supply part is generally supplied by the motor to drive the oil pump. This oil supply main station is large in size, complex in structure (requires 220V power supply), and the oil supply flow rate cannot be adjusted, so it is not suitable for construction machinery occasions.

The technical scheme adopted in the utility model is as follows:

An oil-air lubrication system for pulse oil injection, including a lubricating oil tank, which is connected to an oil-air mixing valve through a pulse-type oil injection valve and a pipeline. One end of the oil-air mixing valve is provided with a compressed air inlet, and the other end is connected to the equipment to be lubricated through a pipeline. , The pulse type oil injection valve is provided with an electromagnetic reversing valve with a controller, and the pipelines on both sides of the pulse type oil injection valve are provided with check valves.

The pulse type oil filling valve is directly connected to the hydraulic line of the equipment to be lubricated.

The pulse type oil injection valve includes a valve body, and the oil supply plunger and the electromagnetic reversing valve are respectively inserted in the valve body, and the oil supply plunger is respectively connected to the hydraulic oil inlet and the hydraulic oil inlet arranged on the valve body. Oil outlet, the valve body is provided with a lubricating oil suction port connected to the lubricating oil tank and a lubricating oil outlet connected to the equipment to be lubricated. The use of cartridge valves makes the overall structure compact, and the simple structure greatly improves the reliability of performance.

The beneficial effects brought by the technical solution provided by the utility model are:

The utility model directly uses the hydraulic system of the engineering machinery as power, and uses the electromagnetic reversing valve and the original controller on the engineering machinery to adjust the oil supply flow rate. The utility model has a simple structure and is suitable for various engineering machinery.

The traditional motor-driven oil pump oil supply method requires 220V power supply, the oil supply volume is not variable and the structure is relatively complicated, so it is not suitable for field operations of construction machinery. The utility model can well solve the above problems, and is an oil-air lubrication system suitable for engineering machinery, especially suitable for lubricating down-the-hole impactors or hydraulic rock drills on rock drilling rigs.
