Why do I need to calibrate the school oil pump?

Why do I need to calibrate the school oil pump? When the school pump to the cylinder spray must be a stable time, called the injection timing. If your pump fuel injection at the wrong time, it will cause the cylinder combustion is not normal, a great harm to the engine, and poor combustion will result in increased fuel consumption. First, cleaning. After the long-term use of the oil pump, the oil pump components will wear due to the large amount of dirt deposited inside the oil bunker and the diesel bunker. Second, replace the couple. Long-term use of plungers and discharge valves can cause wear and tear, resulting in a drop in oil supply pressure. Caused by smoking, oil, lack of motivation and other symptoms, need to be replaced on a regular basis. In addition, long-term use of the oil seal will be aging, resulting in oil spills, need to be replaced. Third, the school oil pump to adjust the oil, long-term use of the pump oil will change, you need to adjust according to the data. So go to the regular school pump to school pumps, such as pump service station, because only they can have the pump data.

Hot Pipette Tips

The commonly used Pipette kits are mainly composed of a pipette and a pipette tip. The pipette tip is a single empty
Cavity reservoir; the pipette uses the principle of air displacement and controls the maximum displacement of the piston by rotating a screw with an ultra-fine thread
displacement, and then control the amount of liquid suction. There are the following problems when using the above kit for suction: 1. The suction volume is controlled by the pipette
After the pipette is sterilized or used for a period of time, it is easy to cause "hidden" failures, which cause the operator to be difficult to detect.
The actual suction volume is inaccurate, and it needs to be adjusted frequently, and the operation is cumbersome and time-consuming; 2. To improve the pipetting accuracy, the operator's
The operation requirements are high, and it is easily affected by factors such as the suction speed, the depth of the tip below the liquid level, and the inclination angle of the pipette.
The actual suction volume will be heard; 3. The actual suction volume will be affected because the suction head cover is not tight and leaking, and it will not be easily detected; 4.
When performing experiments that require high accuracy, such as analysis, in the operation of equal volume aspiration of liquids with different densities, the actual
The actual suction volume will be affected by the density itself; 5. In order to improve the accuracy, this type of pipette needs to carry out high
Cost-optimized design results in extremely high pipette costs.
