Do you really understand the high temperature oil pump? - - - - - -

select heat pump and understand its main parameters are inseparable, these parameters including the pump capacity, rated flow, the theory of traffic, nominal revolution, etc. , among them:

1. Displacement ( 毫升/ r) : every turn a circle pump can discharge the liquid quantity;

2。 Theory of traffic ( L/min) : under the rated revolution, through the calculation method of maximum flow per unit time pump can discharge;

3。 The rated pressure ( Mpa) : can ensure that the pump can run for long hours under normal working conditions of high pressure;

4。 The rated flow, L/min) : under normal working conditions long-term runtime can output the maximum flow.

5。 The rated RPM ( r/min) : can ensure the normal operation of long time under pressure rated one of the biggest revolutions;

6。 Maximum revolutions ( r/min) : under the rated pressure, allowed to pump in a short period of time more than the maximum speed of the rated speed;

7。 Drive power ( 千瓦) : under normal working conditions can drive hydraulic pump mechanical power.

usually, should undertake choosing according to the actual working conditions of system. In order to improve the system reliability and prolong the service life of heat pump, can be between 70% and 80% of the rated pressure of the pump selection of fixed equipment in the normal work of the hydraulic system pressure. The work of the hydraulic system pressure the rated pressure of the pump selection between 50% to 60%.

select heat pump is the second most important factors of pump flow or displacement. Pump flow related to the working conditions. The selected pump flow hydraulic system must be greater than the maximum flow of operation.

pump efficiency values reflect the quality of the pump. In general, the host of the commonly used operation parameters should be high efficiency of the pump efficiency curve area.

in addition, should not be used at the same time the high temperature oil pump of the maximum pressure and maximum speed, in order to prolong the service life of pump.

speed selection should be in strict accordance with the specifications specified data in the table, and shall not exceed the maximum speed. As for the lowest speed, under the condition of normal use without restrictions.
