As the current concrete construction machinery welcomed by the construction machinery and equipment, pump truck with the use of time prone to a variety of losses and failures, so the maintenance is very important on weekdays, especially the core components, the key parts Maintenance is particularly important now Xiaobian to introduce the pump daily maintenance and repair methods. Pump daily maintenance and repair methods Pump several key parts should pay particular attention to, such as manual grease pump, oil cup lubrication, concrete pistons, boom, legs and other weekday to be more maintenance. Now for these key parts of the maintenance work, one by one to introduce. Manual grease pump Before each boot and after the pump is finished, wash the entire vehicle, and then check and maintain manual grease pump filled with oil filled tank, pull the handle of the grease pump to observe the mixing bearings, S tube The size of the head, if there is a clean oil spill can be. In the course of their work, the hand pump handle should be pulled 10 times every 1 hour. At the same time keep the lubrication system clean, prevent dust and other impurities from entering, do not come into contact with acids and bases, and clean the system once every 500 hours of work. Lubricate the oil cup two swing valve cylinder seat, each with a cup of lubricant. Before pumping starts, grease must be filled into the cup and screwed on to lubricate the cap. During the working process, the cap should be lubricated once every 4 hours so that the spherical friction surface is in a good lubrication state. Concrete Pistons, when the transport cylinder coating (0.2-0.25 mm) is not worn away and the rear of the concrete piston tank that appears concrete slurry or sand, it indicates that the piston has worn immediately replace the concrete seal body, guide ring, dust ring . Since the piston can be withdrawn to the pumping system tank through simple operation on the control panel, the piston should always be checked out regularly. In addition, after the piston is retracted to the tank, the concrete sealing body and the guide ring on the piston should be cleaned, meanwhile Apply lithium grease lubrication, this can effectively extend the piston life. Boom, outrigger and turntable maintenance Pumping joints in the various sections of the arm at the hinge point, the four legs and support the connection shaft and turntable these locations specifically designed butter nozzle, usually requires 60 working hours Lubricate the grease point (grease nipple). Normally lubricate with grease until oil spills. Replace the gear oil once every 500 working hours for the rotary reducer with the rotary reducer. Lubricate all the gear surfaces of the rotary reducer regularly every 3 months. If there is any dirt on the gear surface during the inspection, it should be removed immediately , To prevent damage to the gear, resulting in downtime and maintenance costs. It should be pointed out that, weekly through the refueling seat on the nozzle with a grease gun to the slewing bearing grease; once the fastening nut and bolt loosening phenomenon should be immediately replaced, not allowed to continue the construction to prevent accidents Accident happened.
