Plunger water pump integrated application system

Abstract

The invention discloses a plunger water pump integrated application system. The plunger water pump integrated application system is characterized by comprising a motor, a first coupler, a transfer case, a plurality of plunger water pumps, a water suction pipeline, a water pressing pipeline and a lubricating oil system, wherein the power of the motor is transmitted to an input shaft of the transfercase through the first coupler, the power is transmitted to a plurality of output shafts of the transfer case through an intermediate shaft, each plunger water pump is fixed on one side of the transfer case and is connected with the corresponding output shaft of the transfer case through a second coupler, the water suction pipeline is correspondingly connected with water suction openings of all the plunger water pumps, the water pressing pipeline is correspondingly connected with water pressing openings of all the plunger water pumps, and the lubricating oil system provides lubricating oil for each plunger water pump. According to the plunger water pump integrated application system, a perfect lubricating system and a concise water suction and water pressing pipeline system are adopted astechnical support, so that the high-pressure plunger pumps can run reliably for a long time, and the problems of low efficiency of a centrifugal pump under a high lift and small displacement of a single plunger water pump are well solved.

Description

technical field [0001] The invention relates to the technical field of plunger water pumps, in particular to an integrated operation system of plunger water pumps. Background technique [0002] In high-lift applications, the efficiency of centrifugal pumps is low, and it is difficult to meet the qualified indicators of energy-saving operation. However, the high efficiency of plunger pumps is more and more popular with people, and even has a tendency to completely replace centrifugal pumps. However, compared with the advantages of large displacement and high speed operation of the centrifugal pump, the displacement of the plunger water pump is small and the operating speed is low, which cannot meet the water supply demand of large flow. If the displacement and speed are increased too much, it is necessary to increase the cylinder The diameter of the sleeve and the plunger increases the pulse movement of the plunger, which intensifies the vibration of the pump body, thereby ac...

Problems solved by technology

[0002] In high-lift applications, the efficiency of centrifugal pumps is low, and it is difficult to meet the qualified indicators of energy-saving operation. However, the high efficiency of plunger pumps is more and more popular with people, and there is even a tendency to completely replace centrifugal pumps.

However, compared with the advantages of large displacement and high speed operation of the centrifugal pump, the displacement of the plunger water pump is small and the operating speed is low, which cannot meet the water supply demand of large flow. If the displacement and speed are increased too much, it is necessary to increase the cylinder The diameter of the sleeve and the plunger increases the pulse movement of the plunger, which intensifies the vibration of the pump body, thereby accelerating the failure of the vulnerable parts of the pump body, reducing the service life of the plunger water pump, increasing maintenance costs, and reducing production efficiency.
