The detection chamber is communicated with the first hydraulic pipe 105 and is located at one end of the first hydraulic pipe 105. The second hydraulic pipe 117 is communicated with the detection chamber and is located at one end of the detection chamber. The second connecting pipe 119 is communicated with the second hydraulic pipe 117 and is located at one end of the second hydraulic pipe 117. The pressure detector 118 is embedded inside the detection chamber. The installation chamber 103 installs and fixes the hydraulic pump 101 and the electrical signal receiving end 102. At the same time, the electrical signal receiving end 102 controls the hydraulic pump 101, so that the output end of the hydraulic pump 101 pumps hydraulic oil into the first connecting pipe 104. The hydraulic oil is pumped out from the output end of the hydraulic pump 101, and the hydraulic oil is successively pumped into the first connecting pipe 104, the first hydraulic pipe 105, the detection chamber, the second hydraulic pipe 117 and the second connecting pipe 119, and finally is pumped into the corresponding equipment through the second connecting pipe 119. The detection chamber installs and fixes the pressure detector 118, and the pressure detector 118 is used to detect the oil pressure passing through the detection chamber in real time. The oil pressure signal can be used as a control signal. The pressure detector 118 converts the oil pressure into an electrical signal, and then the electronic control system controls the hydraulic system.

[0019] Among them, the detection chamber includes a chamber body 106, a flange cover plate, a pressure assembly, a plurality of oil seal rings 113, and a detection sleeve 114. The number of the oil seal rings 113 is multiple groups. Each group of the oil seal rings 113 is respectively embedded inside the chamber body 106. The detection sleeve 114 is embedded inside the chamber body 106 and is placed inside the multiple groups of the oil seal rings 113. The pressure assembly is arranged at the upper end of the detection sleeve 114. The flange cover plate is arranged at the upper end of the pressure assembly, and the flange cover plate is detachably connected to the chamber body 106 by bolts. The pressure detector 118 is embedded into the detection sleeve 114. After the detection sleeve 114 and the pressure detector 118 are placed inside the chamber body 106, the detection sleeve 114 and the chamber body 106 are sealed by the oil seal rings 113 to prevent hydraulic oil from leaking out. Then the pressure assembly is placed at the upper end of the detection sleeve 114. Finally, the flange cover plate is fixed to the upper end of the chamber body 106 by bolts, and the flange cover plate realizes the sealing.

[0020] Secondly, the detection sleeve 114 has multiple groups of convex rings 115. The multiple groups of the convex rings 115 are evenly arranged inside the detection sleeve 114, and the multiple groups of the convex rings 115 are mutually adapted to the outer surface wall of the pressure detector 118. The detection sleeve 114 also has multiple groups of embedded grooves 116. The multiple groups of the embedded grooves 116 are evenly arranged at the upper end of the detection sleeve 114. By embedding the multiple groups of the convex rings 115 into the outer surface wall of the pressure detector 118, the sealing performance between the detection sleeve 114 and the pressure detector 118 is improved.

The resisting spring 111 is located between the pressure bottom plate 110 and the flange cover plate. By the mutual adaptation and clamping of the embedded rings 112 and the embedded grooves 116, the sealing performance between the pressure bottom plate 110 and the detection sleeve 114 is improved. By the resisting spring 111, the extrusion strength between the pressure bottom plate 110 and the detection sleeve 114 can be improved to prevent loosening during the sealing process, and further improve the sealing strength between the detection sleeve 114 and the pressure bottom plate 110.

[0022] In addition, the flange cover plate includes a cover body 107, a positioning block 108 and a rubber ring 109.

The detection bin mounts and fixes the pressure detector 118, and the pressure detector 118 is used to detect the oil pressure passing through the detection bin in real time. The oil pressure signal can be used as a control signal. The pressure detector 118 converts the oil pressure into an electrical signal, and then the electronic control system controls the hydraulic system. The pressure detector 118 is embedded in the detection housing 114. Then, the detection housing 114 and the pressure detector 118 are placed in the housing 106. The detection housing 114 and the housing 106 are sealed by the oil seal ring 113 to prevent the leakage of hydraulic oil. The pressure assembly is placed on the upper end of the detection housing 114. Finally, the flange cover plate is fixed to the upper end of the housing 106 by bolts, and the flange cover plate realizes the seal. Through multiple groups of the convex rings 115 being embedded into the outer wall of the pressure detector 118, the sealing performance between the detection housing 114 and the pressure detector 118 is improved. Through the engagement of the embedding ring 112 and the embedding groove 116, the sealing performance between the pressure bottom plate 110 and the detection housing 114 is improved. Through the abutting spring 111, the extrusion strength between the pressure bottom plate 110 and the detection housing 114 can be increased, avoiding loosening during the sealing process, and further improving the sealing strength between the detection housing 114 and the pressure bottom plate 110. The positioning block 108 holds the end of the abutting spring 111 away from the pressure bottom plate 110 to prevent the abutting spring 111 from being displaced. The rubber ring 109 realizes the seal between the cover body 107 and the housing 106. By installing and fixing the cover body 107 with bolts, while ensuring the sealing strength, it is convenient to quickly disassemble and assemble the cover body 107.
