Diesel pump will usher in golden development period

When the diesel engine water pump suddenly flows into the water during its use, it will be difficult to reinstall it. Open the outlet pressure gauge and the inlet vacuum pump, and then slowly open the gate valve as it shows the appropriate pressure, while checking the load of the pump group.
To control the flow and head of the diesel pump as far as possible, it is necessary to use it within the range indicated on the sign to ensure that the diesel pump runs at the efficiency point so as to achieve energy-saving effect. During the operation of the pump, we should pay attention to the change of flow and head at all times. The installation of diesel engine pump is also very particular, in the dust cover side of the same to the impeller side to install, the installation of grease filling, must not forget. After 24 hours of running, the diesel pump should inject lubricating grease into the bearing with a grease gun.
It is not allowed to adjust the flow rate by entering the valve on the pump of diesel engine, so as to avoid cavitation. The pump should not operate continuously under rated flow rate. If the pump must operate under this condition, a water injector should be added separately, and the flow rate can reach above the above minimum. Check the loose ground condition of the diesel pump frequently, whether the pump shell temperature and the inlet temperature are consistent, check the vibration of the pump regularly. In the process of using the diesel pump, there will be leakage. There are many specific reasons. Can be divided into two different situations to distinguish, a large number of leaks can not occur, and a small number of leaks can be discharged through the leak pipe to receive. It is not surprising that a small amount of leakage is normal at the beginning of the operation.
When the conveying medium transfers heat to the pump cover and bearing of the diesel pump, the heat is dissipated by the surface of the pump cover and bearing seat, so that the temperature of the bearing seat coincides with the temperature of the shaft density. Therefore, when selecting the installation position of the diesel pump, do not have any heat storage phenomenon. When designing the flow rate of diesel pump, it is necessary to consider the specific operating environment, regardless of whether the flow rate is designed to be large or small.  Both can not be separated from the design of diesel pump body and impeller structure, as far as the design of a single pump body, there are many different forms.
The diesel pump is flat, expansive, spiral and so on. The impeller of diesel pump has clearance of different distances, which can be divided into single-stage and multi-stage, closed and open type. The larger the clearance, the faster the flow through, of course, its premise is that the configuration of the engine horsepower to match the impeller selection. The use of diesel pump is very extensive, used in many places where water needs to be pumped, especially in the field where sewage needs to be removed.
