Description

Technical Field

[0001] The utility model relates to the technical field related to a water pump base, in particular to a large-displacement water pump base. Background Art

[0002] The large displacement water pump base is used to support and fix the bottom part of the large displacement water pump. It is usually used to install large water pump equipment to ensure that the water pump is firmly installed on the ground or other supporting structures. The design of the base usually takes into account the weight of the water pump and the working environment to ensure that the water pump can operate safely and stably.

[0003] The large displacement water pump base of the prior art has the following disadvantages during use:

[0004] On the one hand, the base is only fixed in the designated installation position by bolts, and it is not easy to move. Even if it can be moved, it is achieved by four universal wheels, and the brake structure set on the universal wheel needs to be operated manually separately, and it is impossible to achieve synchronous braking positioning of the four universal wheels at the same time, which makes it inconvenient to use;

[0005] Secondly, the height of the water pump is also set at a fixed height and cannot be easily adjusted. Even if the height needs to be adjusted, it is pre-raised by adding pads, which makes it very inconvenient to adjust the height. For this reason, we have designed a large-displacement water pump base to solve the above problems. Utility Model Content
