There are many ways to adjust the flow of the gear oil pumps. Today we introduce three common flow adjustment methods.
The flow rate of the gear oil pump is the amount of medium required to be pumped in the production of the process unit. The flow unit is generally expressed in m³/h or L/min.
The first is speed regulation, which is the most common. Both the gear pump and the centrifugal pump are suitable for this method. The main principle is to adjust the flow rate by adjusting the speed of the pump shaft. The power loss of this method is small, but it is necessary to increase the speed governing mechanism or select a speed regulating motor to change the speed. Of course, variable frequency adjustment can also be used to change the speed of the motor. The gear oil pump, high viscosity pump, internal tooth pump and other series produced by our company use this method to adjust the speed.
Another way is bypass regulation, which uses bypass shunt to regulate flow, which is commonly used in reciprocating pumps. It can solve the problem that the pump runs continuously under a small flow rate, but this way, the power loss is large, and more pipelines need to be installed.
The third way is the outlet valve adjustment. This method is suitable for centrifugal pumps. A regulating valve is installed on the outlet line, and the flow rate is adjusted by the opening degree of the valve. This method is simple to operate, but the power loss is large and uneconomical. The flow regulation of the reciprocating pump is not suitable for this method.
