Small concrete pump truck FAQ
Now, in construction on the pump is an irreplaceable role in the. Here is truck driver in the operation often encounter a variety of problems, here HAOMEI Machinery equipment Co., Ltd. Star-ming will provide you with answers to frequently asked questions:
1, pump arm fast how slow the point?
You can adjust the parity above multi-way valve orifice screw, thereby regulating the flow sheet valve, to regulate the speed of the purpose of the boom. Manufacturers do not recommend you to adjust the relevant buttons.
2. Pump Truck shaking too much how to deal with?
Inside the cabinet to turn off the boom cushioning effect but little more, or adjust the boom position and then put a small displacement or more, as the legs firmly support some, the problem itself steel boom.
3, how to lift GPS lock boom pump?
If you do not pay the car models are recommended on schedule or not lifted, manufacturers know very troublesome. If you have already paid the car models it can only be modified electronic control of the whole, not computer controlled.
4, concrete pump truck pumped back why not?
Concrete pump can not be pumped to the car, although the turntable can take 365-degree rotation of the boom can be turned back, but the center of gravity in the truck behind the car, back after pumping more rearward center of gravity mobile, the risk of rollover-prone, it is not pumped back! This situation can be put down to drive around a little on it.
5, the general construction of concrete pump require much space?
Almost to a diameter of 12 meters of space to be conducive to the smooth terrain it additional pump, next have to have a space for a U-turn mixer. But in general depends on the width of the front legs and rear legs, pumping the length of the pump is not the same. Secondly Also note that there is no space above obstacles such as wires, finally, to ensure the normal and depart into the concrete mixer, preferably have two venues car the car will meet the above requirements on it.

The reason of small concrete pump truck oil temperature too high
We use a small concrete pump to work when sometimes encounter the oil temperature rise quickly, very high, and it was found unable to pump commutation failure to solve this problem we must first analyze its reasons, experienced drivers master should be aware that this situation is mostly caused by the hydraulic system leak. Well, we are going to talk about it on the specific troubleshooting methods:
We can check the hydraulic pressure of the oil outlet for this failure, if pressure is normal on the import and export and then measuring the accumulator pressure, if the pressure is low, then the accumulator air bag has been broken, replace the accumulator If the test machine fault still exists, you can check the oil between the pump and the accumulator, since between the pump and the accumulator is not compromised,Therefore only possible within the one-way valve between the pump and the accumulator vent lead to temperature rise, reversing weakness. Just down within a period of time, be able to hear the pressure oil unloading "hissing" sound, you can open a one-way valve, you will find the sealing surface of the valve is badly worn, and the hydraulic oil cloudy, with a slight emulsification. You can now replace the check valve and hydraulic oil after the test machine, you can find Tuobeng return to normal.
The current small pump products, most with a 1-2 or hydraulic oil table, a whole oil, a branch table. Then with the oil temperature table, when found in the mailbox of the hydraulic oil increases, often need to determine the cause of the failure to use the above exclusion, despite the exclusion of time required is also not a lot. But at the construction site, as early as one minute if you can solve the problem, the construction unit, is to reduce the losses and increase the benefits.

How to Maintenance the key parts of small concrete pump truck
Small concrete pump as the primary machinery of its construction machinery and equipment efficiently popular market, in the size of the project site can be seen in its presence. But for the construction work of high intensity, small truck with the increased use of time prone to various losses and failures, so weekdays maintenance is critical, especially the core components, critical parts of the maintenance is particularly important!
Small concrete pump truck as the current much welcomes the concrete construction machinery and equipment, which several key parts of the pump accessories should particularly pay attention to, such as manual grease pumps, lubricating oil cup, concrete pistons, arm, leg and so on weekdays to pay more maintenance. Now for several key parts of the maintenance work, each row of concrete were introduced:
Manual grease pump
After pumping before the end of each boot and you want to clean the vehicle, and then check and maintain grease filled manual grease pump storage tanks inside, pulling the grease pump handle, observe stirred bearing, S tube size spindle head place, if you can have a clean, grease overflows. In the course of their work should be pulled manually every hour on the grease pump handle 10 times. While maintaining a clean lubrication system to prevent dust and other contaminants from entering, do not contact with acid substances while working 500 hours each time cleaning the system.
cups oil lubrication
Two swing seat valve cylinders, each with a lubricating cup. Before pumping begins, it must fill up the grease into the oil cup and capping grease lubrication. Operation, should cap Lubricate every four hours, so that the spherical friction surface in good lubrication condition.
arm, leg and table maintenance
At the hinge point of the concrete pump truck boom sections, the four legs of the connecting shaft and bearing and turntable designed several positions butter mouth, usually required every 60 working hours to lubrication points (grease fittings) oil . It should normally be fully lubricated with grease until oil overflows.

How to dismantl of small concrete pump boom system
After any mechanical device used for some time, there will be some natural wear and tear, or inexplicable failures. This time if the following situations, you may need dismantling of small concrete pump truck boom system.
1, small truck boom maintenance is not good, the pin and the copper liner wear serious, we need to replace the pin or jib boring;
2, connecting rod or pin transformation;
3, the replacement of a new boom.
The first step: a small concrete pump can not work unless it is, on the contrary are otherwise removed from the beginning of the last boom, when installed in order. The final forearm flat on the ground, and with good wood pad, penultimate section arm and arm into the required angle of 5-10 degrees, in order to avoid arm cylinder in extended or retracted extreme position.
1.a small pump this last boom cylinder on the compression balancing valve is opened to relieve pressure. Because it is high-pressure oil, so the relief time to pay attention:
Loosen the balancing valve pressure regulator, the attention to the original position be marked, or write down Loosen laps. If you need to remove the balancing valve shall be installed with a cloth face balancing valve and the cylinder block, to prevent high pressure oil discharged wounding.Use a hammer to the boom cylinder and linkage pin knocked out, hanging under the fuel tank. If the pressure relief valve has been removed, be careful not to spill.
2.the arm and the link pin to knock them out, slightly lift the penultimate section of the boom, the last section of the boom for demolition is completed.
3.Remove the copper sleeve, copper sleeve and the pin to be checked, if you need to replace worn.
4.Install boom and cylinders, pay attention to the pin direction.
5.If you previously removed a balancing valve, now need to install and adjust the dynamic balance valve pressure balance valve on the fuel tank, the pressure to return to the previous setting.
6.Start and begin operating the boom, boom see whether the firm or have no oil spill situation. Note: When operating the boom, the smallest possible margin, no person shall close the boom range of motion.
