High temperature oil pump is mainly composed of shell, rotor, bearing, seal and other parts. It adopts packing sealing structure and adds temperature resistant oil seal to play the role of auxiliary sealing. The pump and motor are connected by three claw elastic coupling. The traditional hot oil pump structure is changed from the design, and the cooling mode of natural heat dissipation is adopted, which reduces the volume of the pump, makes the structure simple, saves the operation cost, safe and reliable.

What I want to share with you today is the reasons for the low efficiency of high temperature oil pump:

1. The efficiency of the product itself is a fundamental impact. Under the same operating conditions, the efficiency of the pump may vary by more than 15%.

2. Before start-up, employees do not pay attention to the preparations before start-up, and the basic operating procedures such as warm-up pump, disc pump and filling pump are not fully implemented, which often leads to pump cavitation, pump noise, vibration and low pump efficiency.

3. The efficiency of the motor remains basically unchanged during operation. Therefore, it is very important to choose a high-efficiency motor.

4. The operating condition is lower than the rated condition of the pump, with low pump efficiency and high energy consumption.

5. The influence of mechanical seal efficiency is mainly related to design and manufacturing quality. After selecting this product, the impact of later management is very small.

6. Volume loss, also known as leakage loss, includes three leakage losses: impeller seal ring, interstage and axial force balance mechanism. The level of volumetric efficiency is not only related to design and manufacturing, but also related to later management. After the pump runs continuously for a period of time, due to the friction between components, the gap increases and the volumetric efficiency decreases.

7. Oil pump loss includes oil pump friction and local resistance loss. After the pump runs for a certain time, it will inevitably cause the surface wear of impeller and guide vane, increase the loss of oil pump and reduce the efficiency of oil pump.

8. The product is evacuated and idled due to the blockage of filter cartridge, water inflow of pipeline and other reasons.
