Pay attention to the pressure when the pump truck is in use

Purpose: To guide the pressure adjustment of the pumping, reversing, stirring, and washing hydraulic systems of the sky pump. Adjustment steps: Loosen all the adjustment screws of the main relief valve on the main valve block and all the relief valves on the auxiliary valve block.

How to solve the pumping distance of the pump truck

The section end boom is crimped and at the end of the extended section boom the concrete is pumped out of the attached discharge hose using the pipe switch. This solution can effectively reduce the height and length of the boom during pumping, so as to achieve the purpose of saving. However, the pipe switching device and unloading hose added to the curled part of the end boom have a great influence

How to pump when the head of the pump truck is not high?

When the concrete pump is carrying out short-distance pumping construction with low head and short distance, it only needs to erect the first boom hinged with the boom turret, and then unfold the fourth and fifth booms at the end. The jib combination for short-distance pumping is composed of the first, fourth, and fifth-section booms to meet the needs of short-distance pumping construction. At this time, the second and third section booms lean against the head boom.

The working principle of the pump truck when pumping concrete

Working principle of concrete pump Concrete pump (support pump) is composed of hopper, pump body, hydraulic cylinder for driving slide valve, slide valve, conveying cylinder, main hydraulic cylinder and pilot valve. When the main hydraulic pump drives the concrete piston to retract, under the push of the mixing blade, the concrete poured into the hopper is sucked into the delivery cylinder through the suction port of the slide valve. When the main hydraulic cylinder moves forward,

Relevant safe operation of pump truck outriggers

The outriggers of the sky pump play a very important role in the whole car. If the chassis is not stable enough, it will fall easily. Therefore, the stability of a car has a crucial relationship with the outriggers. Whether the outriggers can be stably attached to the ground is also a very important link in the safety inspection of sky pumps.

What is the approximate cost of concrete pump maintenance

1. Pump pipe: a set of good quality wear-resistant pipe, the service life is generally about 30,000 cubic meters of concrete, that is to say, it must be replaced after 30,000 cubic meters of concrete is hit. Therefore, according to the annual pumping of 100,000 cubic meters of concrete machinery, at least 3 sets of pump pipes must be replaced a year.

The importance of hydraulic cylinders to truck mounted concrete pump

The number of hydraulic cylinders used in the concrete industry is very high, and different numbers of cylinders are used according to the number of different arms. A balance valve is used on each cylinder, which shows the importance of the balance valve, so today we will analyze it and possible problems.

Pay attention to the use of related parts of pump trucks

Anyone who has used a pump truck knows that the pump truck is particularly expensive for lithium-based grease, commonly known as butter, because of the special structure of the hopper. In order to ensure that the shaft is not intruded and worn by concrete, the butter is continuously overflowed from the sealed cavity, and the concrete Push it outwards to protect the inner shaft and bearings by consuming grease.

What are the common pump truck piston problems

Since the piston of the concrete pump truck is a very important part, it needs to be in direct contact with the concrete, so the requirements for it are also very high, and there are very strict requirements for sealing and wear resistance, so sometimes if Something happened, and we should also think about whether it is a problem with the piston.

Pump truck be careful when extending the boom

. Before moving the boom and extending the outriggers, check whether there are obstacles around. Prevent the jib or outriggers from touching buildings or other obstacles. When the operator cannot observe the entire work area or cannot accurately determine the distance between the outstretched part of the pump truck and adjacent objects, a guide should be assigned to command.

The seal of the gate valve is limited by the structure, and attention should be paid to the construction of the concrete pump truck

The sealing of the gate valve is limited by the structure, and the sealing pressure is low. It is inevitable to use a Y-shaped pipe to connect the double cylinder of the concrete pump and the delivery pipe during construction, and the Y-shaped pipe will cause a large pressure loss. In addition, when the gate valve is used for conveying, it is also required to install a horizontal conveying pipe section in front of the vertical conveying pipeline,

How to maintain the pump truck to prolong its service life

As a popular pumping equipment at present, concrete pump truck can greatly improve construction efficiency and is very popular with construction parties. However, in order to prolong the service life of the concrete pump, it is necessary to carry out the necessary maintenance, which can be carried out from the following aspects.
