Abstract
The utility model discloses a novel water-feeding pump tensioning device, which comprises an oil pump, a pipeline, a hydraulic oil cylinder and a movable block. The hydraulic oil cylinder is provided with an annular cavity, a hydraulic oil seal and a piston. The movable block is threadedly connected with a screw. The screw is simultaneously and threadedly connected with a pump body. The screw is also provided with a nut. Due to the adoption of the tensioning device, the fastening of all tensioning bolts is relatively uniform. Meanwhile, the tensioning work strength of a water-feeding pump is reduced and the working efficiency is improved.
Description
Technical field
The utility model relates to water pump and loads and unloads used auxiliary equipment field, and device is used in especially a kind of novel feed pump tension.
Background technology
At present, the connection of the inlet segment of feed pump, stage casing, water exit end all uses the turnbuckle nut of screwing on fastening, during concrete operations, all is to lean on that artificial to use big spanner to add upper bush fastening.Working strength of workers is big, and each turnbuckle is fastening inhomogeneous, be prone to produce the stress of pump, phenomenon such as cause vibration, leak.
The utility model content
The utility model technical assignment is to above-mentioned technical deficiency, provides a kind of novel feed pump tension to use device.
The technical scheme that the utility model technical solution problem is adopted is: device is used in novel feed pump tension; Comprise oil pump, pipeline, hydraulic jack and movable block; Said hydraulic jack place is provided with toroidal cavity, hydraulic seal and piston; The said movable block screw rod that has been threaded, this screw rod is threaded with the pump housing simultaneously, also is provided with nut on the said screw rod.
The beneficial effect that the utility model can bring is:
1, each turnbuckle is fastening even relatively, and has reduced working strength, has improved operating efficiency.
Description of drawings
Fig. 1, the utility model overall structure sketch map.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done following detailed description:
Shown in accompanying drawing 1; Device is used in the novel feed pump tension that the utility model is announced; Comprise oil pump 1, pipeline 2, hydraulic jack 3 and movable block 6, said hydraulic jack 3 places are provided with toroidal cavity 9, hydraulic seal 4 and piston 5, said movable block 6 screw rod 7 that has been threaded; This screw rod 7 is threaded with the pump housing simultaneously, also is provided with nut 8 on the said screw rod 7.
During concrete the use, oil pump 1 is transported to hydraulic jack 3, toroidal cavity 9 with oil, and piston 5 promotes movable block 6 and moves right.Simultaneously, owing to movable block 6 and screw rod 7 are threaded, and screw rod 7 is threaded with the pump housing, so screw rod 7 also moves right accordingly, the position that is connected with screw rod 7 in the pump housing also is tightened up accordingly.
The utility model can make the fastening even relatively of each turnbuckle, and has reduced the working strength of feed pump tension, has improved operating efficiency.
