Asphalt pump is a popular and widely used positive displacement pump. It is specially used to transport asphalt. People are habitually called asphalt pump. At present, there are several types of pumps in the market that can be used to transport asphalt. Hebei Shenghui Pump Industry Co., Ltd. will analyze it for everyone.

After the YCB arc gear oil pump is used for a period of time, the gear will gradually wear out during the continuous rotation process, resulting in a decrease in flow rate and a decrease in delivery pressure. In order to achieve the initial conditions of use, it is necessary to replace a new oil pump or The oil pump is being repaired. The technicians of Hebei Shenghui Pump Industry are here to talk about several key points of the repair.

The double screw pump is a positive displacement pump with active screw meshing. There are many structural forms. Today, let's talk about the characteristics of the oilfield two screw pump.

Internal gear pumps are also called high-viscosity pumps or high-viscosity gear pumps. They are different from ordinary external gear pump gears. The internal gear pump consists of an outer rotor, which is separated and fixed by a crescent plate and a pin. The rotor, the inner and outer rotors run in the same direction, and they are relatively stable after running, with low noise and no pulsation. Especially suitable for conveying highly viscous materials.

The hot cooking oil pump should be considered from five aspects according to the process flow and the oil supply and discharge requirements, including liquid delivery volume, device head, liquid properties, piping layout, and operating conditions.

There are mainly the following two factors that cause abnormal noise and abnormal vibration of the centrifugal pump.
​​​​​​​In terms of medium:
1. It is possible that the centrifugal pump sucks debris into its internal structure, causing blockage or damage to the impeller. At this time, shut down immediately and take quick cleaning at the same time;
2. The flow rate of the centrifugal pump has relatively large fluctuations, which leads to pressure changes, and then produces abnormal noise and abnormal vibration.
3. The suction stroke is too large, causing serious cavitation at the entrance of the impeller, that is, the water flowing on the impeller produces certain bubbles in the low-pressure zone, and these bubbles are destroyed in the high-pressure zone, which will produce Certain impacts, such impacts are more serious, and vibrations will find abnormalities. If this happens, the installation height of the centrifugal pump should be lowered.
