In recent years, the kerosene gas phase drying equipment industry has strengthened external and intra industry exchanges. Both the comparison of the whole industry with the same industry abroad and the comparison within the industry have exposed our existing problems and gaps. I think these problems are common and must be taken seriously in the future.

Since China's entry into WTO, the vacuum equipment industry has faced more and more problems. The market competitiveness can not meet the needs of the rapid development of the national economy, and its own situation can not adapt to the complex market competition situation. Although we have solved the immediate problem of eating in recent years, where is our market in the long run? How can we improve our technology and face the market? Do we have any advantages to fight with foreign companies? These realities that have been put in front of us can not but arouse our thinking in the vacuum equipment industry. While thinking about these problems, we must find ourselves and understand ourselves. Only in the face of existing problems can we analyze and solve them. The oil filling pump is the main component of the oiler. Each oil injection pump is fixed on the box with screws, and the rotation of the camshaft pushes the lever to swing around the support pin. When the eccentricity of the cam decreases gradually, the plunger moves downward under the action of the spring, forming a vacuum in the plunger sleeve of the pump body. Due to the action of atmospheric pressure, the lubricating oil is sucked from the oil suction pipe, and the sucked lubricating oil enters the drip pipe through the oil inlet pipe in the pump body. At this time, the oil in the sight glass is also in a vacuum state, so that the vacuum sucks the oil out of the drip pipe, and the sucked oil enters the pump body again through the small hole in the sight glass, so that the inside of the sight glass becomes a closed path. When the eccentricity increases gradually, the plunger moves upward to discharge the lubricating oil through the oil filling valve and send it to each lubricating point. The required number of oil filling pumps can be arranged on the box according to the number of lubrication points of the user.
