Description

Concrete drag pump test device

technical field

The utility model relates to the field of test device equipment, in particular to a concrete drag pump test device.

Background technique

With the rise of modern industry, the construction method with concrete as the main material has become one of the main structures in the construction industry, accounting for a large proportion of various engineering constructions. Concrete drag pump, referred to as drag pump, is one of various concrete machinery, used for conveying and pouring in concrete construction.

After the concrete towed pump is assembled, it is necessary to conduct a system pressure test to ensure the stability of the system pressure and meet the product technical conditions before it can become a qualified product; at present, the towed pump test device is to install a large number of delivery pipes on a large bench, and the test When using water as the medium, the water is pumped into the delivery pipe through a towed pump, and a pressure gauge is used at the pump outlet. If the pump works continuously for more than 10 hours and the pressure is stable, the pump meets the requirements for stable pressure, otherwise it does not. However, the current device has the following disadvantages: it must be in a fixed site, the structure is huge, and it takes up a lot of space; the system pressure is controlled by the number of delivery pipes in the test device. After the installation is completed, the pressure cannot be adjusted, and each device can only measure one Pressure value; there are many pipe joints, easy to leak; material and processing costs are high, resulting in low test efficiency and high cost.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a concrete drag pump test device of the present invention includes a frame body 1, a gate valve 2, and a first pipeline 3. One end of the gate valve 2 is connected to the outlet pipeline of the concrete drag pump, and the other end is connected to the outlet pipeline of the concrete drag pump. The first pipe 3 is connected.

Specifically, a pressure gauge is installed on the concrete drag pump, and the internal pressure of the pump can be measured through the pressure gauge. The test device uses water as the medium to control the size of the outlet of the gate valve 2, thereby controlling and adjusting the internal pressure of the concrete drag pump. , when the outlet of gate valve 2 becomes smaller, the internal pressure of the pump becomes larger; when the outlet of gate valve 2 becomes larger, the internal pressure of the pump becomes smaller. During the implementation process, the water bucket 10 is filled with water, and the pumping work starts. By observing the value of the pressure gauge, the size of the outlet of the gate valve 2 is adjusted, and the internal pressure of the concrete drag pump is controlled to reach the pressure that needs to be tested. Under this pressure If the pump works continuously and stably for more than 10 hours, then under this pressure, the pump meets the requirements of the product. Then change the outlet size of the gate valve to test whether the pump can work stably under other pressures.

Specifically, the gate valve 2 is a high-pressure gate valve. The utility model is a pressure testing device used for testing concrete drag pumps. The pressure used by concrete drag pumps is relatively high, and ordinary gate valves cannot meet the requirements. High-pressure gate valves need to be selected.

Specifically, it also includes a second pipeline 4 and a third pipeline 5, the second pipeline 4 is connected to the first pipeline 3 through the first pipe clamp 6, and the third pipeline 5 is connected to the first pipeline 3 through the second pipe clamp 7 The second pipeline 4 is connected, and the outlet of the third pipeline 5 is arranged on the bucket 10 . This setting can make the test water recycle, without causing waste and saving water.
