Description
Technical field:
the invention belongs to the technical field of water-spraying type plunger slurry pumps, and particularly relates to an intelligent water-spraying system of a water-spraying type plunger slurry pump.
The background technology is as follows:
when the water-spraying type plunger slurry pump works, high-pressure clean water is required to be conveyed to the plunger combination position of the slurry pump through the flushing pump to clean the plunger, so that the purposes of prolonging the service lives of the plunger and the filler are achieved. And meanwhile, a great amount of clean water resources are wasted by cleaning the plunger. In the prior art, the flushing pump simply keeps the pressure difference water supply flushing slurry pump plunger, but in practice, the operation mode of the water spraying type plunger slurry pump causes that the three-phase plunger cannot realize synchronous operation, and in the same time, when one plunger discharges slurry (a high-pressure area), a large amount of high-pressure clean water resources overflow into the slurry along with the other plunger (a low-pressure area) sucking the slurry, so that the plunger (the high-pressure area) discharging the slurry cannot be flushed effectively all the time, and the suction plunger is flushed excessively. This phenomenon results in a great amount of high-pressure clean water loss in the low-pressure area when the plunger sucks in the slurry, and the plunger has a small flushing water amount when the plunger discharges the slurry (in the high-pressure area), so that the abrasion of vulnerable parts is increased, and clean water resources are wasted.
The invention comprises the following steps:
the invention aims to design an intelligent water spraying system of a water spraying type plunger slurry pump, which solves the problem that when a three-phase plunger of the slurry pump is in reciprocal reciprocating motion, the water spraying system washes clean water supply and demand for the plunger, so as to ensure that the clean water resource for washing the plunger reaches three-phase supply and demand balance no matter when the plunger discharges slurry (a high-pressure area) or sucks slurry (a low-pressure area).
The technical solution of the invention is as follows: the utility model provides a water spray type plunger slurry pump intelligence water spray system, includes water spray type plunger slurry pump spray system, characterized by: the water spraying type plunger slurry pump spraying system is connected with a clear water flushing pipeline I and a clear water flushing pipeline II in parallel, the clear water flushing pipeline I and the clear water flushing pipeline II are connected with a high-pressure clear water pipeline in parallel through an electromagnetic valve I and an electromagnetic valve II respectively, and the clear water flushing pipeline I and the clear water flushing pipeline II are connected with a low-pressure clear water pipeline in parallel through an electromagnetic valve III and an electromagnetic valve IV respectively; the tail end of the plunger of the water-spraying plunger slurry pump is provided with a signal emitter, a signal receiver I and a signal receiver II are arranged on a pump shell of the water-spraying plunger slurry pump side by side, the signal receiver I corresponds to the signal emitter up and down when the plunger is about to enter a high-pressure area for discharging slurry, and the signal receiver II corresponds to the signal emitter up and down when the plunger is about to end for discharging slurry; the signal transmitter, the signal receiver I and the signal receiver II are respectively connected with the signal input end of the PLC control system, the control signal output end of the PLC control system is respectively connected with the control ends of the electromagnetic valve I, the electromagnetic valve II, the electromagnetic valve III and the electromagnetic valve IV, and the PLC control system is used for respectively controlling the electromagnetic valve I and the electromagnetic valve II to be communicated with a high-pressure clean water pipeline to flush a plunger located in a high-pressure area; and respectively controlling the electromagnetic valve III and the electromagnetic valve IV to be communicated with a low-pressure clean water pipeline to flush the plunger positioned in the low-pressure area.
The signal transmitter is an infrared signal transmitter, and the signal receiver I and the signal
The receivers II are all infrared signal receivers.
The high-pressure clean water pipeline and the low-pressure clean water pipeline are arranged above the pump shell of the water spraying type plunger mud pump through supporting plates.
According to the invention, by introducing two paths of flushing clear water with different high and low pressures and detecting and controlling the intelligent control system, when the plunger is used for discharging the slurry at a high pressure area, the high-pressure flushing water valve is opened, and when the plunger is used for sucking the slurry at a low pressure area, the low-pressure flushing water valve is opened, so that the water supply separation of the flushing clear water at the high pressure area and the flushing clear water at the low pressure area in the reciprocating motion of the plunger is realized, the plunger is used for sucking the slurry at the low pressure area and flushing the low pressure clear water, and when the plunger is used for discharging the slurry, the high pressure area is flushed by the high pressure clear water. The plunger is guaranteed to be effectively flushed in a high-pressure area and a low-pressure area all the time, the service life of sealing bodies such as filler is prolonged, clean water leakage caused by flushing the low-pressure area by high-pressure water is reduced, and clean water resources are saved.

fig. 2 is a control schematic of the present invention.
The specific embodiment is as follows:

1. The signal transmitter 11 is an infrared signal transmitter, and the signal receiver I12 and the signal receiver II 13 are both infrared signal receivers. The PLC control system is integrated in an electric cabinet of the water-spraying type plunger slurry pump. The high-pressure clean water pipeline 8 and the low-pressure clean water pipeline 9 are arranged above the pump shell of the water spraying type plunger slurry pump through the supporting plate 14.
When the invention is used, the high-pressure clean water pipeline 8 is connected with high-pressure flushing clean water, and the low-pressure clean water pipeline 9 is connected with low-pressure flushing clean water. According to the invention, by detecting the reciprocating track of the plunger, when the plunger is about to enter a state of discharging the slurry high-pressure area, the signal receiver I13 corresponds to the signal emitter 11 up and down, the signal receiver I13 receives signals, the signals are sent into the PLC control system, the PLC system is processed, the electromagnetic valve I4 and the electromagnetic valve II 5 are opened, and the plunger in the high-pressure area is sufficiently cleaned by high-pressure flushing clear water; when the plunger discharges slurry to be finished, the plunger enters a state of sucking the slurry into a low-pressure area, the signal receiver II 12 corresponds to the signal emitter 11 up and down, the signal receiver II 12 receives signals, the signals are sent into a PLC control system, the PLC system is processed, the electromagnetic valve III 6 and the electromagnetic valve IV 7 are opened, and the plunger in the low-pressure area is sufficiently cleaned by low-pressure flushing clear water.
