Problems solved by technology

With the rapid development of the economy, hydraulic technology has been applied to industrial production and life due to its advantages of light weight, small size, small motion inertia, fast response, and convenient manipulation and control. In order to facilitate the development of the economy, it has injected new vitality into the development of the economy. However, hydraulic motors have extremely precise requirements for accessories, and it is difficult to find faults, which brings challenges to the repair of hydraulic motors. Due to the different sizes and powers of hydraulic motors, the test The requirements are different, and a maintenance test method for different hydraulic parts is needed

Embodiment Construction

[0024] A hydraulic motor maintenance test method, using a hydraulic maintenance operation platform, the selected test items for maintenance are: displacement verification test, efficiency test, impact test, variable characteristic test, pressure vibration inspection, self-priming test, high temperature test, overspeed test , Overload test, full load test, external leakage inspection test;

[0025] Among them, the displacement verification test is divided into the following steps:

[0026] 1. Make the hydraulic motor unloaded, even if the load of the hydraulic motor is zero, or the output pressure of the hydraulic motor does not exceed 5% of the rated pressure or does not exceed 0.5MPa;

[0027] 2. Set a uniform 5-speed speed within the range from the minimum allowable speed to the rated speed of the hydraulic motor, and measure the motor flow under the condition of each speed n; n is the actual speed r / min; N is the number of speed measurement gears; q is the effective output...

Abstract

The invention discloses a hydraulic motor overhaul testing method. A hydraulic overhaul operation table is utilized, and overhaul selected test items comprise a displacement validation test, an efficiency test, an impact test, a variable property test, a pressure oscillation examination, a self-sucking test, a high temperature test, an overspeed test, an overload test, a full-load test and an outward leakage examination test. By selecting the test items, a hydraulic axial plunger pump, a plunger motor, a hydraulic gear pump and a hydraulic blade pump can be overhauled on the hydraulic motor overhaul operation table through the method, compatibility of overhaul equipment is achieved, the operation method is simple, test performance is stable, and overhaul quality and maintenance efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a method for maintaining a hydraulic motor, in particular to a method for maintaining and testing a hydraulic motor. Background technique [0002] The hydraulic motor is an actuator of the hydraulic system, which converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. With the rapid development of the economy, hydraulic technology has been applied to industrial production and life due to its advantages of light weight, small size, small motion inertia, fast response, and convenient manipulation and control. In order to facilitate the development of the economy, it has injected new vitality into the development of the economy. However, hydraulic motors have extremely precise requirements for accessories, and it is difficult to find faults, which brings challenges to the repair of hydraulic motors. Due to the different sizes and powers of hydraulic m...
