Pressure lubrication refers to the addition of an oil pump to the engine, using the pressure of the oil pump to force the oilto supply various components. Pressure lubrication is a forced lubrication that mainly relies on the pressure generatedby the oil pump to deliver the lubricating oil. Pressure lubrication isused for the lubrication of friction surfaces witrlarge loads such as main bearings, connecting rod bearings, cam bearings, etc. The function of pressure lubrication is tochange the performance of the product, and the improvement of lubrication can reduce the temperature between parts.which is conducive to improving the toughness of the product.
Pressure lubrication is the process by which an oil pump precisely distributes oil to critical areas of the pump. Typicallythe oil is fed into the pump through an oil filter, where it is then recovered and reused; The use of replaceable oil filterscan further improve the life of the oil. Oil is delivered to critical areas through the use of oil pumps.
Advantages of pressure lubrication system:
1. lmprove lubrication effect, Pressure lubrication makes the softeningpowder coating effect good, reduces mold wear, reduces the impact of mold replacement on operation efficiency, andimproves output: Reduce frictional heat generation and avoid lubrication failure due to high temperature.
2. lmproveproduct performance. lmproved lubrication can reduce the temperature of the steel wire, which is conducive to improvingthe toughness of the product. Due to the reduction of friction and the different stress states during deformation, the yieldstrength of the product can be slightly improved.
3. Can improve the pulling speed. If the cooling capacity, lubricatingmaterials and mold potential of the wire drawing equipment have been fully utilized, and the motor capacity is stilsurplus, good lubrication can reduce the load of the equipment cooling system, better ensure the surface quality, andpressure lubrication can continue to improve the wire drawing speed. lt is especially obvious for pickling-freephosphating technology, and the pulling speed of pickling-free phosphating treatment is very low in the absence of gooolubrication technology.
For the pressure lubrication system with shaft end pump, it is necessary to automatically control the start and stop of themain motor driving the reducer through the pressure switch, which can effectively protect the speed reducer fromdamage due to insufficient lubrication when the oil pressure is low.
The working principle of the pressure lubrication system: For the pressure lubrication system with shaft end pump, it isnecessary to automatically control the start and stop of the main motor driving the reducer through the pressure switchwhich can efectively protect the reducer from damage due to insuficient lubrication when the oil pressure is low. At themoment of starting the main motor, because there is no oil pressure in the oil circuit of the pressure lubrication systemso that the pressure switch contact does not operate, the main motor cannot be started. Therefore, it is necessary toconnect a delay relay in the control loop, and the delay is set for about 20 seconds, so that the main motor can bedirectly powered on within 2 seconds of the initial start, and the pressure switch does not play a control role.
