Technical Field
The invention relates to the technical field of drilling, in particular to an automatic stop alarm for a drilling mud pump under low oil pressure.
Background
In general drilling operation, an oil pump of a drilling mud pump operates independently and is not interlocked with a main body working mechanism of the pump.
At present, the prior art has the following problems: once the oil pump fails and stops working, the slurry pump can still run as usual until the pump is damaged and dies. Or, a great deal of material cost is wasted, the operation progress is influenced, the construction is unsafe, and even safety accidents can happen.
