Hydraulic detection system and method for secondary water supply device

Abstract

The invention belongs to the technical field of secondary water supply, and particularly relates to a hydraulic detection system and method for a secondary water supply device. The hydraulic detectionsystem comprises a water tank, a water inlet hose and a water outlet hose, wherein the water inlet hose and the water outlet hose are connected with a to-be-detected device, the to-be-detected deviceis connected with a to-be-detected frequency-conversion cabinet, the upper end of the water tank is connected with a water return pipe, and the side portion of the lower end of the water tank is provided with a water outlet pipe. The water outlet pipe is connected with a first pressure pipe and a second pressure pipe in parallel, and the first pressure pipe and the second pressure pipe are converged into a booster pump water outlet pipe until the booster pump water outlet pipe is communicated with the water inlet hose. By means of the hydraulic detection system, combined operation check of various types of secondary water supply devices and control cabinets of various specifications can be achieved. The secondary water supply devices have various forms, such as pressure-stabilization typepressure superposition, water tank type pressure superposition, frequency-conversion constant pressure, compensation type pressure superposition and a mobile pump station, and all the secondary watersupply devices can be detected on the platform.

Description

technical field

[0001] The invention belongs to the technical field of secondary water supply, and in particular relates to a hydraulic detection system and detection method of secondary water supply equipment. Background technique

[0002] For urban secondary pressurized water supply equipment, the equipment and the control cabinet cannot be inspected jointly before leaving the factory, and only simple inspections can be carried out separately. The airtightness test of the mechanical part of the equipment, that is, the equipment is considered qualified if it does not leak water. The frequency conversion control cabinet is only inspected for appearance and wiring firmness.

[0003] The equipment cannot operate, equipment noise, vibration, operation stability, various data detection, function detection, etc. cannot be carried out, the control parameters of equipment operation cannot be calibrated, and the quality of the whole equipment cannot be guaranteed.
