[0002] "Cranking" means turning the pump shaft by manpower or a pump cranking tool before starting the pump unit. This is to determine whether the load driven by the motor (i.e. the mechanical or transmission part) is stuck and the resistance is increased, to prevent internal jamming and scratching of the pump, and to avoid damage to the motor (i.e. burning out) due to increased load when the motor starts.

[0003] The pump shaft of the pump used in the chlor-alkali production industry is generally large, and the labor intensity of the operator is high when manually operated, and the work efficiency is low.

However, due to the space limitation in the pump body, the long force application handle leads to the limited degree of movement of the pump turning tool on the pump shaft, which in turn makes it inconvenient for the operator to turn the pump shaft, and cannot be well adapted to the turning of the pump body used in the chlor-alkali production.

[0020] Among them, 1-clamping component one, 2-clamping component two, 3-connecting bolts, 4-force column, 5-assisting rod, 6-rubber pad. DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention, but the present invention is not limited to the implementation methods described below.

[0022] Example

[0023] See also Figure 1The present embodiment provides a disc pump tool, including a clamping component 1 and a clamping component 2 2. The clamping component 1 1 and the clamping component 2 2 are semicircular structures with the same structure. The clamping component 1 1 and the clamping component 2 2 are engaged on the pump shaft. The clamping component 1 1 is connected to the clamping component 2 2 by a connecting bolt 3.

[0024] The inner walls of the clamping components 1 and 2 are both provided with rubber pads 6, which increase the fitting force between the clamping components 1 and 2 and the pump shaft, so that the clamping components 1 and 2 and the pump shaft are tightly held to prevent relative displacement between the pump turning tool and the pump shaft during turning, causing friction and damage to the pump shaft.

[0025] Both the clamping assembly 1 and the clamping assembly 2 are provided with force columns 4 along the outer wall, and the force columns 4 include a first force column and a second force column. The first force column is provided on the clamping assembly 1, and the first force column and the clamping assembly 1 are welded or integrally cast, and the second force column is provided on the clamping assembly 2, and the second force column and the clamping assembly 2 are welded or integrally cast. One or more first force columns are provided along the outer wall of the clamping assembly 1, and when multiple first force columns are provided, multiple first force columns are evenly spaced on the clamping assembly 1. Similarly, one or more second force columns are provided along the outer wall of the clamping assembly 2, and when multiple second force columns are provided, multiple second force columns are evenly spaced on the clamping assembly 2.

[0026] Preferably, in this embodiment, three first force-applying columns are provided on the clamping component 1, and the three first force-applying columns are respectively located at three equal parts of the outer arc of the clamping component 1; similarly, three second force-applying columns are provided on the clamping component 2, and the three second force-applying columns are respectively located at three equal parts of the outer arc of the clamping component 2, so that the position of the second force-applying column provided on the clamping component 2 corresponds to the position of the first force-applying column on the clamping component 1.

[0027] The length of the force column 4 is 0.2 to 1 m, which can better adapt to the space limitation in the pump body. For a small pump body, by rotating the force column 4, the operation of the disc pump can be made more convenient and labor-saving. For large pump bodies used in the chlor-alkali production industry, in order to increase the torque of the force column 4 and make the disc pump more labor-saving, a booster rod 5 is provided on the force column 4, and the force column 4 and the booster rod 5 are detachably connected, so that the booster rod 5 can be removed from the force column 4 after the pump shaft is rotated to a certain angle, and reconnected to the force column 4 at a suitable angle, so that the user can rotate the pump shaft easily, saving labor and not being limited by the space in the pump body.

[0028] Specifically, a countersunk hole is set at one end of the booster rod 5, and the booster rod 5 is sleeved on the end of the force column 4 through the countersunk hole; further, in order to reduce the weight of the force column 4 and the booster rod 5, the force column 4 and the booster rod 5 are both set as hollow structures. Further, the length of the booster rod 5 is preferably 0.5 to 1m; further, in order to save more effort when using the booster rod disc pump, the length of the booster rod 5 is set to be greater than the length of the force column 4.

[0029] The working principle of the pump turning tool of this embodiment is: clamp the clamping assembly 1 and the clamping assembly 2 2 to the pump shaft, connect the clamping assembly 1 and the clamping assembly 2 2 through the connecting bolt 3, and for a small pump body, rotate the force column 4 to rotate the pump shaft. Generally, the turning wheel needs to be rotated no less than one and a half circles. When it rotates to a certain angle, the force column 4 is replaced in sequence to apply force, which is convenient for the operator to operate and is more labor-saving than direct pump turning by manpower.

[0030] For large pumps in chemical industries such as chlor-alkali, a booster rod 5 is installed on the force column 4. When the booster rod 5 is rotated to the point where the force angle is limited by the space in the pump body, the booster rod 5 is removed from the current force column 4 and re-installed on the force column 4 with a suitable force angle to apply force. This solves the problem that the booster rod of the existing pump tool is too long and is limited by the space in the pump body, resulting in a limited force angle. After turning the wheel to check that there is no abnormality in the pump shaft, the pump is started to ensure the working condition of the pump body.
