Some customers can't load new gear pumps, they rush to call for reasons. Some customers are anxious to say that the quality of our gear pumps is not good. In fact, some of them are not the reasons for the gear pump itself. Below we Here are a few reasons why you can't feed on this issue:
1. First, check if the dust bag on both sides of the gear pump is broken. Some customers do not know this problem. Please pay attention to this issue. Because our oil pump is tested beforehand at the factory, which is what we often call the test pump, this will ensure that the customer has no problem when using it, and then import and export a dust-proof thing to prevent some dirty things. inside.
2, the direction of rotation of the gear pump is not correct, look at the starting direction before starting is the same as the label we posted, we must get the direction of the gear pump.
3, Check if the valve of the suction valve or the discharge valve is open, and if it is closed, it will start running, so that it can not be loaded.
4, Look at whether the imported material can enter the pump, and then see if the pressure is too low, which causes the gear pump to not feed.
5, The medium to be pumped is not within the range of the selected pump. For example, the viscosity of some medium is too high, and the number of revolutions of the selected gear pump is too fast to enter the pump and thus does not feed.
6, check whether the pipeline is not well sealed, there is a leak in the place can not be normally loaded.
