The difference between choosing the right heat transfer oil pump and centrifugal screw oil pump

July 03, 2023

1. The heat transfer oil pump is a pump that transports oil with a higher temperature. Generally, it does not need to be centrifugal, so it is easy to vaporize the hot oil, and generate a gas chamber to damage the impeller of the pump. Generally, the screw type and the gear type are used.

2. If the pump is constructed, the screw pump can be divided into a single screw pump, a twin screw pump and a three screw pump. Gear pumps can also be divided into internal gear pumps and external gear pumps, which are generally used to transport oils with low viscosity. The centrifugal oil pump is composed of a pump casing and an impeller. All kinds of pumps are of this type and their applications are quite extensive.

3, centrifugal, screw, gear oil pump type difference is as follows: First of all, from the principle of the pump can be divided into positive displacement pump and rotary pump. They each have advantages and disadvantages and are suitable for conveying different quality liquids.

(1) Positive displacement pumps are used to transport liquids due to changes in the volume of the pump: such as screw pumps and gear pumps;

(2) The rotary pump is driven by the rotation of the pump wheel to drive the liquid: for example, the centrifugal pump, which requires less stringent liquid quality.

4. The types of heat transfer oil pumps currently available on the market can be described as a wide variety. Therefore, the characteristics, functions and practicability of the heat transfer oil pump should be noted.
