Debugging instructions
The commissioning of the hydraulic system should be carried out in the order of pump station commissioning, system commissioning (including pressure and flow, ie actuator speed commissioning and commissioning of the action sequence). A variety of debugging projects, all from the part of the system as a whole item by item, that is, parts, stand-alone, regional linkage, unit linkage, according to the specific circumstances of debugging methods are also different.
(1) Check before commissioning
① before the test machine on the appearance of the hydraulic components and piping, etc. and then a scrub, scrub with a sponge and disable the veil;
② rails, the port and other sliding as required to add enough oil;
③ check the hydraulic pump rotation, hydraulic cylinders, hydraulic motors and hydraulic pump inlet and outlet tubing is wrong;
④ check the hydraulic components, pipelines and other connections are correct and reliable, if the installation error to be corrected immediately;
⑤ Check the position of each handle, confirm "stop", "back", "unloading" and other positions, so that the stroke block fastened in place. In addition, the relief valve of the relief valve is basically full loose, the flow valve handle close to the whole (slow speed), the proportional valve control pressure flow current setting should be less than the small current value;
⑥ Loose the relief valve handle, properly tighten the safety valve handle, so that the relief valve to the minimum working pressure. Flow valve to a minimum;
⑦ Check whether the motor power is consistent with the provisions of the plate, solenoid valve on the form of current (AC or DC) and the voltage on the electrical components with or without special provisions, etc., fully clear and then close the power.
(2) debugging phase
① jog: the first point of the pump, observe the hydraulic pump steering is correct, the power is not only anti-oil output, and sometimes may be an accident, so avoid the beginning of the operation can only "jog". Until the pump sound normal and continuous output of oil and no other abnormal phenomenon occurs before they can be put into continuous operation and no-load debugging;
② no-load debugging: first 10 ~ 20min low-speed operation, and sometimes need to remove the hydraulic cylinder or hydraulic motor and load connection. Especially in the cold season, this low-speed operation without load (warm-up operation) is particularly important, some imported equipment often have strict requirements, and some with a heater to the tank oil temperature. On the low-speed low-voltage operation can be run first test run;
③ gradually uniform pressure to accelerate, the specific method of operation is repeated tightening and immediately choose loose relief valve, flow valve and other pressure or flow control handle several times, and to observe the pressure gauge movements of the changes in the situation and the implementation of the speed of the device changes , The heat pump vibration, vibration and noise and other conditions, found that the problem of targeted analysis to solve;
④ in accordance with the action cycle table combined with electrical machinery to debug a single action, and then transferred to the cycle of action debugging, check the action is coordinated. Debugging process generally out of some problems, such as crawling, shock and non-change and other failures, especially for complex domestic and imported equipment if there is no big problem, we can consult, if necessary, resort to hydraulic equipment production factory;
⑤ Finally into the full load debugging, that is, according to the hydraulic equipment technical performance of the maximum working pressure and maximum (small) working speed test, check the power, heat, noise, high-speed shock, low-speed crawling and other aspects of the inspection of various parts of the oil Situation, often no airborne parts of the pressure increased when the oil spill, found the problem in time to exclude, and this written record
Such as normal work, you can try to test pieces. After the test is completed, the machine is usually restored after parking and the detailed commissioning record is done. Some imported equipment commission records can be used as a basis for claims;
⑥ by the above method of debugging a good hydraulic equipment of the handle, generally do not move, the packaging of the factory should be the equipment should be released all the hand wheel, long-term equipment, the pressure valve hand to release the spring to prevent the spring Resulting in permanent deformation and thus affect the mechanical equipment is enabled when a variety of fault conditions, and ultimately lead to the use of performance.
