摘要： PURPOSE: To reduce weight and to posse excellent characteristics, such as wear resistance and corrosion resistance, by forming an Al-Cu alloy padding layer by TIG welding on the base material of an aluminum alloy cast. CONSTITUTION: A plurality of padding layers 2 of an Al-Cu alloy are formed on a base material 1 of an Al alloy cast to constitute a liquid contact member 3. Further, after the base material 1 of an aluminum alloy cast is molten, the base material 1 of the Al alloy cast is preheated and the Al-Cu alloy padding layers 2 are formed on the base material 1 by TIG welding. This way prevents the occurrence of breakage during welding of the Al-Cu alloy padding layers 2 and improves quality of the liquid contact member 3. Thus, the weight of a pump casing in a complicated shape to which breakage is apt to occur, namely, a pump casing in a complicated shape having diffuse vane formed of a base material of an aluminum alloy cast is reduced and excellent characteristics, such as wear resistance and corrosion resistance, are possessed.

摘要： PURPOSE:To change over the state of operation of a pump easily and positively in a short time. CONSTITUTION:A siphon path 5 is connected to a pumping path 4 communicating with the discharge opening 33 of a pump 3. An air flow path 9 with an on-off valve 10 communicates with the siphon path 5. When the on-off valve 10 is opened, actual head is increased and discharge is reduced because a siphon is not formed. When the on-off valve 10 is closed, the siphon is formed, actual head is minimized, and discharge is augmented.

摘要： PURPOSE: To realize a drainage pump vehicle loaded with a drainage pump, excellent in traveling and stability of an off-road or under water and moreover adaptable to drainage work of a low water level. CONSTITUTION: In this drainage pump vehicle, a boat form body 3 is connected to a pair of right and left rubber-made crawlers 2, and a drainage pump 4 is vertically rotatably fitted to the protruded end part 3b of the body 3. Plural track rollers 9 to be engaged with the crawlers 2 are oil-impregnated waterproof type resin rollers. The body 3 has an rectangular box type upper buoyancy body 3a above the crawlers 2 and a box type lower buoyancy body 3c protruded in the middle between a pair of the crawlers 2 from the bottom plate of the upper buoyancy body 3a. The drainage pump 4 is vertically rotated by a hydraulic cylinder 5 with a fulcrum P, provided on the box type end part 3b of the upper buoyancy body 3a, as a center. The center of gravity of the drainage pump 4 is at the inner position of a vehicle than the fulcrum P at the upper limit position of the drainage pump 4, and a suction port is made downward in a lower position than the crawlers 2 at a lower limit position.

摘要： PURPOSE:To achieve energy saving by discharging water in large capacity by a high lift, and reducing pump outputs. CONSTITUTION:A low lift upper-stage pump 4 and a high lift lower-stage pump 9, which are driven via a common rotary shaft 16, are communicated with respective independent pumping passages 8, 13 and respective independent inflow passages 6, 11. An air pipe 14 having a switching valve 15 is connected to the impeller room of the low lift upper-stage pump 4. At high water levels both of the pumps are operated to perform pumping operation at large capacity or the impeller room of the low lift upper-stage pump 4 is communicated to atmosphere by the air pump 4 and the low lift upper-stage pump 4 is put in gas-water mixed awaiting operation and water is pumped by the high lift lower- stage pump 9.
