With these parts well maintained, every year it's like buying a new pump truck

  As the most popular mechanical equipment in the field of concrete construction, the concrete pump truck has high construction efficiency and is indispensable in the construction site. However, due to long-term, high-intensity construction work, the concrete pump truck is prone to various losses and failures, daily maintenance is very important, especially the core components, important components of the maintenance is particularly important now, for some important parts of the maintenance work, one by one to the pump friends to introduce the maintenance tips, so that the concrete pump truck for a long time.

  1. Grease pump

  Clean the whole vehicle before connecting the power supply and after pumping, check the oil storage tank of the grease pump is full of grease, observe the size of the stirring bearing, S-tube shaft, clean grease overflow. When working, keep the lubrication system clean, prevent dust and other impurities into, not with acid and alkali material contact, and every 500 hours to clean the system.

  2. Swing valve oil cylinder

  Double swing valve oil cylinder seat, each has an oil nozzle lubrication, concrete pump truck in the use of actual conditions, in 5-10 days with a butter nozzle injection, to ensure the normal operation of the vehicle. Grease must be injected into the grease dispenser from the designated grease dispenser (butter dispenser) . Regular, clean, pollution-free EP 1(1 #) extreme pressure lithium grease is recommended as the pumping agent, thinner“000” or“00” grease is easier to maintain in the lubricating parts, not easy to squeeze out or loss.

  3. Voltage regulators

  The system pressure regulator (with barometer) factory set pressure of 6 bar, according to the actual situation can be adjusted pressure, from the point of view of protecting the life of related components, generally do not allow re-pressurization. If something goes wrong with the system, first check that the barometer is at 6 bar, then pull the trachea out to check for any Compressed air coming out of the trachea (along with the exhaust sound) .

  4. Maintenance of boom, outrigger and turntable

  The grease nozzle is specially designed at the hinge point of each arm frame, the connecting shaft of the four legs and the support, and the turntable of the concrete pump truck, and usually needs to be oiled every 10 -15 days. Oil should be thoroughly lubricated until there is an oil spill.

  5. Rotate the reducer

  The Gear Oil of rotary reducer is changed every 500 hours, at the same time, butter is smeared on the surface of the gear every 3 months. If dirt is found on the surface of the gear, it should be removed immediately, prevent damage to gears, causing downtime and maintenance costs. It should be noted that the grease gun is lubricated once a week to the rotating bearing through the refueling nozzles on the base of the refueling machine, and should be replaced as soon as the fastening nut and bolt are found to be loose, and construction is not allowed to continue, to prevent accidents from happening.
