Detailed ways

The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

The utility model proposes a servo blasting test bench, including a blasting test bench body 1, a blasting chamber 2 is arranged on the blasting test bench body 1, a hydraulic pipe can realize blasting detection work in the blasting chamber 2, two corresponding side walls of the blasting chamber 2 are designed to be open, an output end of the hydraulic device of the blasting test bench body 1 is fixedly connected with a hollow plate 3, a chamber is processed inside the hollow plate 3, so that the hydraulic device can work to transport hydraulic oil to the inside of the hollow plate 3, the hollow plate 3 is fixedly arranged on one side of the blasting test bench body 1, and is used to close the open end of the blasting chamber 2, and the blasting chamber 2 and the hollow plate 3 is provided with a sealing door 12 at the corresponding open end. The design purpose is to seal the hydraulic pipe after it is installed in the blasting chamber 2 to achieve safety detection and prevent oil from splashing outside the blasting test bench body 1. The hollow plate 3 is located on one side of the blasting chamber 2 and is fixedly connected with a plurality of connecting ends 4. The outer wall of the connecting end 4 is processed with threads to facilitate connection with the matching hydraulic pipe. The plurality of connecting ends 4 are arranged in sequence with different calibers. The plurality of connecting ends 4 can realize blasting pressure detection for hydraulic pipes of different diameters. The outer walls of the plurality of connecting ends 4 are all provided with electric valves. When the When testing a hydraulic pipe of a certain diameter, it is connected to the corresponding connecting end 4, the electric valve is opened, and the other electric valves are closed, thereby realizing the closure of the through holes of the other connecting ends 4. Several connecting ends 4 are equipped with threaded caps adapted to the hydraulic pipe to be tested. The threaded cap can be screwed on one end of the hydraulic pipe to completely close the internal passage, thereby realizing the pressurization inside the hydraulic pipe. A pressure sensor 5 is installed on the passage connecting the hollow plate 3 and the hydraulic device. The detection end of the pressure sensor 5 is placed in the passage. When the hydraulic device is pressurized, the data detected by the pressure sensor 5 can be obtained by The controller displays that a water supply chamber 6 is provided on one side of the inner part of the base of the blasting test bench, and the water supply chamber 6 is used to store water mixed with detergent. A spray device 7 is provided above the blasting test bench, and a pump body of the spray device 7 is provided in the water supply chamber 6. The pump body can absorb the cleaning liquid to realize transportation. The connecting pipe of the spray device 7 passes through the base and extends into the blasting chamber 2, and the nozzle of the spray device 7 is provided in the blasting chamber 2. The pump body can transport the cleaning liquid to several nozzles through the connecting pipe, and the nozzle can atomize the cleaning liquid and spray it onto the inner wall of the blasting chamber 2, thereby realizing the cleaning of the inner wall of the blasting chamber 2.

It should be noted that the blasting test bench body 1 is located at the top of the blasting chamber 2 and is designed to be arc-shaped, so that when the cleaning liquid is sprayed on its surface, the cleaning liquid can slide down along the arc-shaped wall surface and take away more hydraulic oil.

Specifically, the base of the blasting test bench is located below the blasting chamber 2 and is provided with a collecting chamber 8. The collecting chamber 8 is located directly below the blasting chamber 2. The cleaning liquid can directly slide into the collecting chamber 8 after cleaning the hydraulic oil. A collecting push-pull groove 9 is slidably inserted on one side of the opening of the collecting chamber 8. By adding the collecting push-pull groove 9, the subsequent cleaning work of the staff can be facilitated.

It should be noted that the side wall above the inner cavity of the collecting push-pull groove 9 is thinner than the side wall below and is formed in a stepped shape to facilitate the placement of the filter screen plate and its removal.

Specifically, a filter screen 10 is placed on the top of the collecting push-pull trough 9. When incomplete pipe segments appear after the hydraulic pipe bursts, the pipe segments can fall on the filter screen 10 on the top of the collecting push-pull trough 9, thereby achieving solid-liquid separation.

Specifically, a water injection pipe 11 is fixedly connected to the top of the water supply chamber 6. The water injection pipe 11 is designed to be easy to connect to an external water pipe to facilitate water injection into the interior.

Working principle: First, inject a proper amount of hydraulic oil into the oil storage tank of the hydraulic device, then thread the hydraulic pipe to be tested and its matching connection end 4, and then screw the threaded cap on one end of the hydraulic pipe to be tested to achieve sealing. At this time, close the sealing door 12 and start the booster pump of the hydraulic device to increase the pressure by delivering oil into the hydraulic pipe. When the hydraulic pipe bursts, the data measured by the pressure sensor 5 reaches a peak value, which is the maximum pressure value of the hydraulic pipe, and the oil after the hydraulic pipe bursts will splash into the blasting chamber 2. At this time Water mixed with detergent is injected into the water supply chamber 6 through the water injection pipe 11 and the spray device 7 is started. The pump body of the spray device 7 can absorb the cleaning liquid and transport it to the connecting pipe. The connecting pipe can atomize the cleaning liquid through the nozzle in the blasting chamber 2 and spray it to the inner wall of the blasting chamber 2. When the cleaning liquid slides down the wall, it can clean the oil and fall into the collection push-pull groove 9. When incomplete pipe segments appear after the hydraulic pipe is blasted, the pipe segments can fall on the filter screen plate 10 at the top of the collection push-pull groove 9, thereby realizing solid-liquid separation for subsequent cleaning.
