Description

Technical Field

[0001] This utility model relates to the field of pump station system technology, and in particular to a pump station system module. Background Technology

[0002] A hydraulic pump is a pump that uses liquid as a medium and generates high pressure through electrical or mechanical energy. Its working principle involves a motor driving the pump's rotor or piston to rotate, enabling the pump to transport liquid from a low-pressure area to a high-pressure area, thus producing a high-pressure output. During factory performance testing, hydraulic pumps must undergo testing according to standards and operating conditions, simulating the pump's operating environment to ensure that the closed-loop test requirements at the rated head are met. This involves measuring performance parameters such as flow rate, pressure, and energy consumption.

[0003] An oil pump is a device that mechanically delivers lubricating oil to friction points. Its working principle involves the rotational motion of gears, blades, and other components within the pump body, drawing lubricating oil into the pump chamber. A pressure regulating valve then increases the pressure within the pump chamber, finally pumping the oil out to the parts requiring lubrication. During factory performance testing, oil pumps undergo simulated operating environments to meet the requirements of cyclic testing at rated head, and performance parameters such as flow rate, pressure, speed, and power are accurately measured.

[0004] Hydraulic pumps and lubricating oil pumps have different properties, functions, and structural characteristics, and therefore operate in different environments. Conventional pump station testing systems have limited functionality and can only simulate the operating environment of hydraulic pumps or lubricating oil pumps. Moreover, they can only test one pump at a time, resulting in poor applicability.

[0005] Therefore, this utility model proposes a pump station system module to solve the above problems. Utility Model Content
