Problems solved by technology

[0002] The high-pressure plunger pump forms repeated pumping and pushing of water through the reciprocating movement of the plunger. Since the water inevitably contains impurities, these impurities will adhere to the plunger during the reciprocating movement of the plunger, causing the plunger to contact the stuffing box. Friction is formed between them, causing damage to the plunger surface, and when the impurities on the plunger surface rub against the water seal in the stuffing box, it may cause the loss of the water seal and affect the sealing effect of the stuffing box

Abstract

The invention provides a 100KW-level high-pressure plunger pump with a self-cleaning function, and belongs to the technical field of high-pressure plunger pumps. The 100KW-level high-pressure plungerpump comprises a pump head and a crankcase. A stuffing box is arranged between the pump head and the crankcase, a crank is arranged in the crankcase, the crank is connected with a plunger through a cross head, the plunger is inserted into the stuffing box, a main water seal and an auxiliary water seal are arranged in the stuffing box, a baffle ring is further arranged in the stuffing box, the baffle ring is located at the end, away from the auxiliary water seal, of the main water seal and is in seal connection with the stuffing box, the baffle ring is in clearance fit with the plunger, a cleanwater one-way valve is arranged on the stuffing box, a clean water passageway penetrating through the side wall of the baffle ring is arranged on the baffle ring, and the clean water one-way valve communicates with the clean water passageway. In the plunger water drawing process, clean water can be introduced, the surface of the plunger is flushed, the cleanliness of the surface of the plunger iskept, the service life of the plunger is prolonged, and the pump can work under the working condition that impurities exist.
