1、 Overview
GB / T 2615-2010 High pressure cleaning machine The standard specifies the parameters, technical requirements and test methods of the basic high-pressure cleaning machine. This standard is applicable to the device with rated pressure of 10mpa-300mpa, rated power of 15-500kw, transmission medium of clean water at room temperature, driven by electric motor or other devices.
According to the standard, the conventional high-pressure cleaning machine mainly includes high-pressure water generating equipment (pump), control system, execution system and auxiliary system.

2、 Basic parameters
According to the standard, the rated pressure, theoretical flow rate and motor power of the cleaning machine should meet the requirements in the table; the pressure level can also be determined by the manufacturer according to the needs, and the flow parameters should be adjusted accordingly.
3、 General technical requirements specified in the standard
1. The high pressure cleaning machine shall be manufactured according to the technical drawings and documents
2. The cleaning machine should be equipped with the corresponding filtering system according to the pressure level, and if necessary, the mode of pressurized water inflow should be adopted
3. When the main engine of high-pressure cleaning equipment operates in rated environment, the temperature of lubricating oil shall not exceed 75 ℃, and its temperature rise shall not exceed 45 ℃.
4. The noise of high pressure cleaning equipment in operation should be within the specified range.
The initial flow rate of the overflow valve should not be greater than 10% of the rated flow rate and the static pressure of the pump should not be greater than 10% of the initial flow rate.
6. Cast iron parts of high pressure cleaning equipment shall comply with GB / t9439, cast steel parts shall comply with GB / t11352, and pressure pipe fittings shall comply with GB / t14976.
7. The spray gun valve, pressure regulating overflow valve, foot control valve and spray gun valve shall take off sensitively and operate randomly and reliably during the operation of the cleaning machine.
8. The recoil force of the hand-held gun rod shall not be greater than 1 / 3 of the operator's weight. When the recoil force of the gun rod is greater than 200N, a mechanism shall be set to fix the gun rod.
4、 Detection method
1. The cleaning machine can be put into operation test only after the manufacturing accuracy inspection, assembly accuracy inspection, main parts inspection and pressure test are qualified.
2. Before leaving the factory, the pressure, flow rate, pump speed and motive power of the high-pressure cleaning equipment shall be tested through performance, test run, consistent operation, continuous operation, safety valve, noise, injection and other tests.
5、 Packaging
1. The name plate of the product shall be fixed on the obvious position of each factory cleaning equipment, including the name and model of the equipment, pressure, flow rate, pump speed, power, date of manufacture, number, etc.
