Dry vacuum pump has been widely used

来源: 作者: 发布时间:2019-02-22 463次浏览

During the operation of dry vacuum pump, driven by the motor, the piston in the cylinder moves to and fro through the effect of crank-connecting rod mechanism (rotating motion into linear motion). When the piston moves from the left end to the right end of the cylinder, because the volume of the left chamber of the cylinder is increasing and the pressure of the left chamber space is decreasing constantly, when the pressure in the left chamber space is lower than that in the pumped container, according to the principle of gas pressure balance, the gas in the pumped container is continuously pumped into the left chamber through the suction valve, which is in the process of suction at the moment.

When the piston reaches its rightmost position, the left chamber of the cylinder is filled with gas. Then the piston moves from the right to the left, and the suction valve closes actively at this moment. The gas is gradually tightened as the piston moves from right to left. When the gas in the cylinder reaches the exhaust pressure, the exhaust valve is opened and the gas is discharged, thus completing an operation cycle. When the piston moves from the left end to the right end, repeat the cycle until the pumped container reaches a certain equilibrium pressure.

Dry vacuum pump is a new type of equipment. There are many precautions when using it. Now many people are not very familiar with the use of this equipment, nor are they very familiar with the product knowledge of this product. The following article mainly explains how to adjust the oil quantity of dry vacuum pump. We can understand it.

The fuel injection requirement can be reduced satisfactorily by proper backward start point and early end point, so it can control the whole incineration process, whether at low or high load, near the stop point. This method is suitable for marine diesel engines with high turbocharging and varying speed and load.

When the dry vacuum pump operates, the starting time of oil supply is unchanged, while the end time of oil supply is changed because of the change of the position of the return hole of the plunger sleeve caused by the inclined side of the plunger. The useful stroke of the plunger varies with the viewpoint of the plunger rolling, so the fuel supply changes accordingly.
