Abstract: On Truck-mounted Concrete Pump care instructions
1, hydraulic oil: hydraulic oil is a highly clean working media requirements, and thus the hydraulic oil tank can not be easily opened lid to prevent contamination of the hydraulic fluid. The first 300 hours of work should replace the hydraulic oil after every 600 hours of work to replace a hydraulic oil, hydraulic oil discovered during work emulsification and deterioration of hydraulic oil should be replaced immediately.
2, the oil level gauge: how much oil tank for observation. When work requires its oil level must be at the location specified above scale, such as the lack of hydraulic oil should be added immediately (required special refueling tanker from the port to join the hydraulic oil).
3, the thermometer: Under normal circumstances, the thermometer shows the oil temperature, hydraulic fluid at normal operating temperature 30 ℃ -60 ℃, the maximum oil temperature does not exceed 70 ℃.
4, the drain valve: When the tank for cleaning polluted open exclude oil, usually closed. After 24 hours a week down the drain valve should be open again, excluding precipitation in the water tank at the bottom.
5, the high-pressure filter (main system and boom system each): When the oil filter on the prism pointer finger in green logo, indicating that work, the filter is not clogged; when the pointer to the yellow color logo mark, indicating there are clogging the filter, but can continue to work; when the pointer is pointing to a red logo, indicating severe filter blockage can not continue to work, you must replace the filter immediately, each replacement should also replace the hydraulic oil filter.
6, the air filter (hydraulic tank on): to prevent external debris mixed with air filtration, replaced once every six months.
7, manual grease pump: pumping before each turn and ended after washing the vehicle, inspect and maintain within a manual grease pump storage tank after filling grease, grease pump handle is pulled, observe stir bearing, S the size of the head tube axis at both oil spill clean immediately after. Work, every one hour flipping manual grease pump handle 10 times. Lubrication system should be kept clean to prevent dust and other impurities into, do not contact with acid substances, every 500 hours of work on the system cleaned once.
8, lubricating oil cup: two swing seat valve cylinders, each with a lubricating cup. Before pumping begins, you must fill up the grease into the oil cup and cap grease lubrication. Work, capping lubrication once every four hours, so that the spherical surface friction lubrication in good condition.
9, concrete Pistons: When the delivery cylinder coating (0.2-0.25mm) has not worn off and the rear piston concrete tank that appears concrete or sand slurry, indicating the piston has been grinding for immediate replacement of the concrete seal, guide ring, dust ring . Since the piston can retreat to the tank pumping system on the control panel, simple operation, usually to allow the piston to exit checks regularly, in addition, after the Pistons retreated to the tank, and a guide to the concrete seal on the piston ring cleaning, apply lithium grease lubrication, which can effectively extend the life of the piston.
10, boom, legs and table maintenance: the hinge point at pump boom sections, the four legs of the connecting shaft and bearing turntable designed and butter mouth (mouth butter specific location see concrete pump car manual), requires 60 hours of work for each lubrication points (grease fittings) were oiled. Grease lubricated applications completely, until the oil spill so far.
11, rotating reducer: every 500 working hours for rotation to replace the gear reducer oil once; regular three-month reduction mechanism to rotate all the gear surface smear grease lubrication, the inspection found that the gear surface dirt should be immediately clear, to prevent damage to the gear, resulting in the loss of downtime and maintenance costs; weekly by refueling refueling nozzle seat slewing bearings with grease gun to fill grease lubrication; when once found tightening nuts and bolts loosening, should be replaced immediately, not allowed to continue construction, to prevent accidents.
12, transfer case: ⑴, truck every day before use, should check the transfer case oil lubricating oil should stick button above. That is, when the oil by hand button for 3 seconds, should oil overflowed from the button at. Otherwise, it is necessary from the transfer case of filler refuel. ⑵, every six months or 500 hours of work on the transfer case oil replacement, transfer case for cleaning. Remove dirt and harmful impurities, in order to ensure reliable operation of the transfer case. ⑶, a week on the transfer case coupled transfer case bolts and hanger bolts checks to prevent the bolts loosening due to vibration, shock and even greater damage to the transfer case. ⑷, splitter box lubricating oil level must not exceed the oil level plug, the oil level when the splitter box exceeds the requirements, easy to heat when the transfer case work, so easy to produce lubricant deterioration, affecting Iso gear box and bearing lubrication, serious, due to poor lubrication of bearings and tooth surfaces and burn, resulting in a loss to stop the project maintenance.
13, fastening elements: Daily before starting the check for loose fasteners, such as loose should be tightened only after further work.
14, electrical components: Daily checks before starting the electrical components and wiring is abnormal loose.
15, cylinder seals: 1000 hours per work, replace the cylinder seals once.
16, put the ball valve cylinder head and the upper and lower spherical bearings: Every 500 hours, check the swing valve cylinder head and the upper and lower spherical ball bearings once badly worn that replacement.
17, chassis maintenance: according to the relevant chassis manufacturer's maintenance requirements.
In order to protect and extend the truck-mounted concrete pump life. |
