Abstract:
본 발명에 따른 워터젯 로봇 및 이를 이용한 콘크리트 또는 건설구조물 제거 방법은 파쇄대상 구조물의 표면 높이에 따라 분사노즐의 높이를 자동으로 조절함으로써 콘크리트 제거 작업의 효율성과 품질을 높일 수 있고, 센서의 파손을 방지할 수 있다는 장점을 갖는다.
Abstract:
A nebulizer having a transformation prevention bump according to the present invention comprises: a body having a receiving space which receives a medicinal fluid therein, an atomization space which is connected to the receiving space and atomizes the medicinal fluid, and a spraying port which is connected with the atomization space and sprays atomized medicinal fluid; a gas flow unit which is included in the body and has a gas flow path which moves compressed gas to the atomization space side by being connected to a compressed air generation device; and a medicinal fluid flow unit which is formed to surround the circumference of the gas flow path and has a medicinal fluid flow path which is connected to the receiving space and moves the medicinal fluid to the atomization space through pressure difference by the compressed gas moved to the gas flow path. The medicinal fluid flow unit comprises a plurality of transformation preventing pumps which is protruding to the gas flow unit side along the circumference of the medicinal fluid flow path.
Abstract:
The present invention relates to a drill bit including an internal fluid path and, more specifically, a drill bit improving a drilling rate according to reduction of a pressure loss of a discharged fluid by controlling design factors of a fluid path in order to effectively discharge stone dust. According to an embodiment of the present invention, the drill bit reduces the pressure loss of the fluid flowing in the internal fluid path and effectively discharges the stone dust by using the minimum of a fluid rate.
Abstract:
본발명의제1~3 실시예에따른유량제어장치는전기유압시스템의작동초기에두 개의유압펌프가모두작동유를공급함으로써액츄에이터의구동속도를높일수 있고, 작동초기가경과되면하나의유압펌프만작동유를공급하도록한다는특징을갖는다. 그리고, 본발명의제4 실시예에따른유량제어장치는전기유압시스템의작동초기에리니어액츄에이터를이용하여사판각을증가시켜작동유공급을증가시킴으로써액츄에이터의구동속도를높이고, 작동초기가경과되면사판각을감소시켜작동유공급을감소시킨다는특징을갖는다.
