Note: Because the boom cylinder is extended and retracted in place before oil is discharged, only one chamber of all boom cylinders is filled with oil; the other chamber is filled with oil due to the expansion and contraction of the oil cylinder, so the volume of oil contained in the other chamber is very small and can be ignored. . For example: the boom cylinder is extended in place before oil discharge,

The 32-meter pump truck boom, especially the plates of the first few arms connected to the turntable, generally use high-strength steel plates. When high-strength steel plates ensure yield strength, some indicators such as plasticity, ductility, and weldability are reduced, especially during welding. The thermal stress affected zone formed during the welding process causes the strength of the weld and surrounding areas to decrease.

In the hydraulic system of a concrete pump truck, the outrigger and arm system have certain particularities. For safety reasons, each vertical outrigger cylinder and each boom cylinder are equipped with a balance valve (commonly known as "hydraulic lock"). Only when the reversing valve is opened will the balance valve connect to the oil circuit. Otherwise, the balance valve remains closed, isolating the hydraulic oil inside and outside the cylinder.

Concrete pumps will inevitably suffer losses and malfunctions during use. If we want to reduce the loss to a minimum, then we need to know more about the common problems of concrete pumps, so that we can solve the problems in time at the initial stage of failure. Analysis and solutions to common problems of concrete pumps.

The correct selection of concrete materials is especially important during the wet concrete spraying process of the wet concrete spraying trolley!

What are the uses of concrete pump trucks? Besides pumping concrete, what else can it be used for? In fact, it cannot be used.

Pay attention to these points during the operation of the concrete pump truck. Only by doing so will the use of the concrete pump truck be safe. Share these points with everyone

The market for concrete pump trucks is now very mature and is widely used on construction sites. If you need to use a small concrete pump truck recently, you need to pay attention to the following points when choosing:

What are the solutions to the problem of short-distance pumping by concrete pump trucks? We have been working hard on the road to becoming bigger and stronger, hoping to meet more like-minded partners to jointly develop small pump trucks. According to the structural characteristics of the boom, shortening the boom expansion length requires a concept that can be folded and realize short-distance pumping. The improvements and solutions we have made for this include the following:

Before stopping work, the hydraulic concrete placing boom machine equipment should be maintained for a season, conduct a freezing point test on the antifreeze used, and replace the antifreeze suitable for the climate conditions of the region. Fuel, lubricating oil, and hydraulic oil must use the brands specified in winter, and preheating and heat preservation devices must be installed.

The main personnel involved in installation and disassembly must be familiar with the performance structure and characteristics of the hydraulic concrete placing boom, be technically proficient, and have the ability to troubleshoot.

Qingdao Saintyol DAWIN machinery Co., Ltd. is an enterprise that develops large-scale construction engineering machinery and equipment integrating scientific research, production, sales and after-sales service. The company's main products include (D) and other various concrete conveying equipment.

1. When extending and folding the hydraulic concrete placing boom, each action should be performed independently, and actions cannot be combined to avoid accidents.

Maintenance before work

1. For electrical equipment, check whether the wet concrete spraying machine shotcrete instruments, buttons, air pressure switches, ball valves, and motor temperatures are normal.

1. The hydraulic hydraulic placing boom arm is out of control

1. Hydraulic concrete placing boom hydraulic system
Check the oil level of the hydraulic device and add enough hydraulic oil if necessary.
Before starting the machine, open the oil drain port of the hydraulic device to drain the condensed water.

(1) The performance parameters of the hydraulic concrete placing boom should be reasonably matched with the performance parameters of the concrete pump.

How to deal with problems when using the concrete mixing pump, The concrete mixer pump is a commonly used concrete pumping equipment in construction projects and one of the indispensable tools in modern construction projects. However, no matter how good the product is, it may wear out or malfunction. If the problem is not serious, there is no need to go to the after-sales service. We can repair it ourselves.

The role of cement in the pumping process The pumping pressure of concrete is transmitted by the liquid phase in it. The liquid phase carries the solid phase to move together to complete the pumping. Cement has two functions. One is the cementing effect, which makes the concrete maintain the state of solid phase surrounded by liquid phase during pumping
