Squeeze type pump

스퀴즈 펌프는 원통형 드럼의 입구와 출구 사이에 배치되고 상기 드럼의 내주변 면을 따라 연장되는 탄성 튜브를 가진다. The squeeze pump has an elastic tube disposed between the inlet and the outlet of the cylindrical drum and extending along the inner peripheral surface of the drum. 180도 간격으로 떨어져 있는 한 쌍의 압박 롤러가 상기 튜브를 압박하기 위해 배치된다. A pair of pressing rollers spaced 180 degrees apart are arranged to press the tube. 상기 튜브는 튜브 내의 시멘트를 이송하기 위한 두 개의 굴곡부를 갖는 편평형으로 변형된다. The tube is deformed into a flat shape with two bends for transporting cement in the tube. 상기 튜브는 입구에서의 대경과 출구에서의 소경을 갖는다. 각 압박 롤러는 중앙에 형성된 대경과 양 끝에 형성된 소경을 갖는다. The tube has a large diameter at the inlet and a small diameter at the outlet. Each pressing roller has a large diameter formed at the center and a small diameter formed at both ends. 상기 튜브가 상기 압박 롤러에 의해 압박될 때 리브는 튜브의 상기 굴곡부의 적어도 하나를 지지하기 위해 드럼의 상기 내주변 면을 따라 연장된다. When the tube is pressed by the pushing roller, the rib extends along the inner circumferential surface of the drum to support at least one of the bends of the tube.

The hose pump which hose guide bar is had

본 발명은 호스 가이드바가 구비된 호스펌프에 관한 것으로서, 보다 상세하게는 아래와 같다. The present invention relates to a hose pump provided with a hose guide bar, in more detail as follows. 첫째, 압축슈가 호스를 정확하게 압축할 수 있도록 압축직전에 압축슈의 중심부로 호스를 유도하여 정확한 압축을 할 수 있도록 한다. First, the compression shoe is capable of accurate compression by inducing the hose to the center of the compression shoe just before compression so that the compression of the hose can be precisely compressed. 둘째, 압축슈가 호스를 압축하면서 지나간 직후 최대한 원래의 모양이 될 수 있도록 호스의 모양복원을 유도한다. Second, induce the restoration of the shape of the hose so that the compression shoe can be as original as possible immediately after passing the hose. 셋째, 펌프가 고압 및 고진공상태에서 펌핑시 호스의 요동에 의한 호스 및 펌프의 손상을 최소화한다. Third, when the pump is pumped under high pressure and high vacuum, damage to the hose and pump due to the fluctuation of the hose is minimized. 넷째, 펌프커버를 열고 호스를 교체해도 호스가 케이싱에서 이탈하지 않는다.

Flexible vane pump

A pump has a rotor with two or more flexible vanes forming one or more compartments between adjacent vanes. The rotor is mounted offset relative to a rotor sleeve such that the volume of the compartments varies as the rotor rotates in the sleeve. Incoming fluid is supplied to the compartments along a plane perpendicular to the plane of rotation of the vanes. Fluid is discharged from the compartments through discharge slots in the sleeve leading into a discharge outlet which is tangential relative to the plane of rotation of the vanes. Each flexible vane is formed from at least two thin leaf springs separated by a layer of laminate and joined to a shoe which engages the inner surface of the sleeve as the rotor rotates. The pump in accordance with the present invention is energy efficient and uses significantly less power than comparable known devices.
