2, is to check the direction of rotation of the pump pump plate should be consistent with the direction indicated, shall not be reversed.
3, is to check whether the hydraulic system laxative loop, can cause full load start and stop, and even reduce the service life of the pump, and the motor overload.
4, is to check whether the safety valve in the system is set on the permit pressure.
5, is the first test drive before the pump, the oil drain should be filled with oil, so that the pump oil, so as not to pump damage due to friction damage components, while the safety valve open.
6, the pump should be carried out in the work of not less than 10min empty load operation, check the pump running sound is normal and the flow direction is correct
1, is to manually rotate the coupling, should feel light, force evenly to identify the pump installed properly.
