Diaphragm pump with automatic protection function and automatic protection method of diaphragm pump

Abstract

The invention provides a diaphragm pump with an automatic protection function and an automatic protection method of the diaphragm pump. Parameters of the diaphragm pump such as diaphragm oil pressure, slurry pressure, piston strokes and the like can be monitored in real time by arranging a first pressure sensor for monitoring oil pressure in a diaphragm oil cavity in the diaphragm pump, a second pressure sensor for monitoring the slurry pressure in a pumping outlet pipeline in the diaphragm pump, a third pressure sensor for monitoring the slurry pressure in a pumping inlet pipeline in the diaphragm pump and a strokes detection sensor for monitoring piston strokes in the diaphragm pump, whether wearable parts such as a valve chamber, the diaphragm, a check valve, a piston cylinder and the like of the diaphragm pump is abnormal or not is automatically judged according to the variation of parameters, so that the automatic protection function of the diaphragm pump can be realized, the maximum service life of each wearable part of the diaphragm pump can be prolonged, the repairing cost of the diaphragm pump can be reduced, and the working efficiency of the diaphragm pump can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of diaphragm pumps, in particular to a diaphragm pump with automatic protection function and an automatic protection method thereof. Background technique [0002] Diaphragm pumps evolved from reciprocating piston pumps in the 1970s by adding a diaphragm chamber, which realized the isolation of the conveying medium from the piston, thereby creating a new advanced conveying technology and equipment. It has many new advantages and features such as long life of wearing parts, easy maintenance, high continuous operation efficiency, low operation cost, high efficiency, energy saving and environmental protection. Diaphragm pumps are the ideal replacement products for traditional piston pumps, slurry pumps, centrifugal pumps, and oil separation pumps. They belong to the core of petrochemical, coal chemical, alumina production, and long-distance pipeline transportation of high-concentration, high-abrasion solid-liqui...

AI Technical Summary

Problems solved by technology

However, the diaphragm pump is a high-value-added and high-tech product. At present, only a few countries such as the Netherlands can manufacture and produce it, making it relatively expensive. Once damaged during use, not only the maintenance cost is high, but the maintenance cycle It is long and will seriously affect the production efficiency of the entire slurry pipeline delivery system. Therefore, it is necessary to protect its vulnerable parts from damage during the operation of the diaphragm pump and maximize the service life of the diaphragm pump. How to realize the diaphragm pump The self-protection function and improving its service life have always been technical problems in this technical field.
