(1) pumping part of the pump maintenance such as pumps work every 8 hours to check the oil quality and oil level of the hydraulic oil, if necessary, supplement and replace, the new hydraulic oil must be added and the oil tank in the oil grade is the same, the pump pump truck factory filling hydraulic oil for Esso H46.
General pumping 20000 cubic metres of concrete or use half a year should be a thorough replacement of oil, oil change must be cleaned oil tank, and the parts of the cylinder for oil treatment.
(2) Check the oil level of the lubricant every 8 hours when the pump is working. It is recommended to use 00# non-extreme pressure type semi-fluid lithium grease for the maintenance of the pumping part of the pump, and there should be lubricant overflow in the concrete cylinder connecting with the water tank, the S-pipe size bearing seat and the mixing end seat when the pump is pumping.
(3) After pumping 3,000 square metres, the pump should adjust the gap between the spectacle plate and the cutting ring, and replace it immediately if it is seriously worn. Check the concrete live should be well sealed, no mortar seepage into the tank.
(4) pump truck after 500 hours of use should check the S tube and S tube bearing position wear condition pump truck pumping part of the maintenance if necessary to replace the bushing and taper sleeve.
(5) check the suction filter of the pump truck vacuum gauge indication such as the position of the vacuum gauge pointer reaches the red zone (i.e., more than 0.04Mpa) must replace the filter element.
(6) in the boot must be checked on each system to see whether the system pressure is normal, check whether the hydraulic system leakage.
(1)The gear oil in the rotary reducer of the rotary table must be replaced after 100 hours of the first use of the pump truck, and then each oil change should be carried out at an interval of 1000 hours (or half a year), and the recommended grade for the maintenance of the pump truck arm is South China Sea 85W-90 heavy-duty gear oil, with a filling volume of 8 litres.
(2) The lubrication at each articulation of the boom and outrigger, the bearing of the slewing large gear ring and the oil nipple at the end of the shaft of the slewing reduction gear should be inspected and oiled every 60 working hours, and the lubricating grease used should be 3# calcium-based grease.
(3) Pump truck boom mounted maintenance in order to reduce the danger of pumping concrete and failure must be used to pump the correct diameter and thickness of the delivery pipe, the correct pipe clamps and safety locks.
(4)Pump truck boom top-loading maintenance In order to make the wear and tear uniform, so that the life of the delivery pipe longer can be regularly rotated delivery pipe: every pouring about 5000 square, straight pipe clockwise turn 120 degrees, bend pipe turn 180 degrees.
(5) pump truck after working for a period of time should be slewing table, boom and outriggers at all places of the weld for careful inspection such as weld cracking phenomenon, should immediately contact with our company for proper treatment.
(6) Pumping concrete work should be completed after the entire pump truck for cleaning is strictly prohibited conveying pipe residual concrete.
(7) Pump truck boom mounted maintenance to ensure the safety of the equipment pump truck is only allowed to connect the front end of the 4-metre hose, not allowed to connect any other pipeline.
(1) concrete pump truck chassis maintenance such as the first use of 50 hours after the oil should be replaced at the same time to replace the oil filter and diesel oil filter, and clean the diesel oil filter and air filter. After every 250 hours replacement.
(2) concrete pump truck chassis maintenance, such as the usual oil level is insufficient to add must be used to meet the requirements of the same grade and type of oil.
(3) Concrete pump truck chassis maintenance, every 10 hours or once a day to check the oil level, such as the amount of oil should be injected in a timely manner.
(4) Concrete pump truck chassis maintenance pickup gear oil should be replaced after 200 hours of use, and each subsequent oil change should be carried out at intervals of 1,000 hours (or half a year), and the grease in the pickup gearbox bearings should be refilled at intervals of 1,000 hours.
