Description

Technical Field

[0001] The utility model relates to a test bench, in particular to a quick installation test bench for both horizontal and vertical pumps, belonging to the field of water pump test equipment. Background Art

[0002] There are many types of pump inlet and outlet directions: flat inlet and upward outlet type, flat inlet and flat outlet type, upward inlet and upward outlet type, etc. At the same time, the center heights of the pump inlets and outlets are different; different lengths and forms of connecting pipes need to be configured for different inlet and outlet directions, which is time-consuming and laborious.

[0003] After the pump is assembled, it is necessary to conduct factory performance tests on the pump to test whether the performance of the assembled pump is qualified; the traditional factory test equipment has the following disadvantages: low automation level and long pump test installation time.

[0004] For pumps with different inlet and outlet directions, different test benches need to be configured, increasing costs and the floor area of the factory building, and cannot meet the existing test requirements.

[0005] In a Chinese patent with a publication date of February 26, 2021 and a publication number of CN112555167A, a utility model patent named "Automated Test Bench for Conventional Vertical Pumps and Its Test Method" is disclosed. This patent meets the function of rapid clamping and testing of vertical centrifugal pumps in the flat inlet and flat outlet direction through a frame, a water passing hydraulic cylinder, a three-way elevator, a tightening hydraulic cylinder, etc. Although this patent provides a rapid automatic clamping and testing device that can meet various types of vertical centrifugal pumps (flat inlet and flat outlet type), it cannot solve the rapid clamping and testing of horizontal pumps with flat inlet and upward outlet for the inlet and outlet.

[0006] Therefore, it is particularly necessary to propose a test bench that is applicable to both horizontal and vertical pumps and has a high degree of automation, for the factory tests of vertical pumps (flat inlet and flat outlet for the inlet and outlet) and horizontal pumps (flat inlet and upward outlet for the inlet and outlet), which can save labor and time costs and improve production efficiency.

The translation and lifting platform is installed in the middle of the base, and the water collection tank is installed on the base. Its characteristics are as follows: It further includes a pipeline horizontal telescopic mechanism, a pipeline vertical telescopic mechanism, a pipeline rotating mechanism, and a hollow hydraulic cylinder.

The pipeline rotating mechanism for the water outlet of the horizontal pump and the water inlet pipe of the water pump are installed on the first vertical frame, and the hollow hydraulic cylinder for the water outlet of a vertical pump is installed on the second vertical frame.

[0009] As an optimization, the present utility model further includes a first flange clamping mechanism and a second flange clamping mechanism. The first flange clamping mechanism is arranged at the lower end of the pipeline vertical telescopic mechanism, and the second flange clamping mechanism is installed at the first end of the pipeline horizontal telescopic mechanism and the water inlet pipe of the water pump.

[0010] As an optimization, the present utility model further includes multiple clamping hydraulic cylinders. Multiple clamping hydraulic cylinders are evenly arranged around the butting flange of the second flange clamping mechanism.

[0011] As an optimization, there are four clamping hydraulic cylinders in the present utility model.

[0012] As an optimization, the water collection tank in the present utility model is arranged on both sides of the translation and lifting platform.
