Marine water pump test device

Abstract

The invention discloses a marine water pump test device. The marine water pump test device includes a motor, a torque meter, a transmission box, a first mounting seat, a sliding seat and a rigid waterinlet pipe; the first mounting seat is detachably connected with a mounting plate, and a first mounting hole corresponding to a water pump to be tested is formed in the mounting plate; the motor, thetorque meter and the transmission box are connected in a transmission mode in sequence, and an output gear of the transmission box is connected to a transmission gear of the water pump to be tested in a transmission mode; and the rigid water inlet pipe slides axially along a center hole of the sliding seat, and a first flange corresponding to a water inlet of the water pump to be tested and a second flange connected with a soft water inlet pipe are separately fixed to two ends of the rigid water inlet pipe. The marine water pump test device has good versatility, is suitable for the test of different types of marine pumps, is convenient to operate, improves test efficiency and reduces the cost.

Description

technical field [0001] The invention relates to the detection of marine water pumps, in particular to a test device for marine water pumps. Background technique [0002] Marine diesel engine cooling water pumps have complex structures, large volumes, heavy weights, large flow rates, and high performance requirements for parameters. It consists of motor, motor coupling, torque meter left coupling, torque meter, torque meter right coupling, pump installation angle iron, pump test coupling, pump inlet pipe, pump outlet pipe, base and other components. The motor, the motor coupling, the left coupling of the torque meter, the torque meter, and the right coupling of the torque meter belong to the common parts of the test bench and are fixed on the base. On the base, the specific installation position needs to be adjusted according to the corresponding length of the pump test coupling protruding from the pump seam surface, so that the pump test coupling is compatible with the righ...

AI Technical Summary

Problems solved by technology

During the test, due to the inevitable axial series movement of the superimposed pump shaft, the torque meter needs to bear the action of dynamic and irregular loads, which is easily damaged, and the failure rate of the torque meter is high

[0005] 3. For the same batch of test products, every time a cooling water pump is replaced, it is necessary to completely disassemble and remove the cooling water pump inlet pipe to remove the tested cooling water pump. A large amount of liquid dripping, polluting the workshop environment

[0006] 4. Before the cooling water pump is tested on the bench, it is necessary to install the pump test coupling at the position where the transmission gear of the cooling water pump to be tested is installed. The pump test coupling is connected with the torque meter coupling as a tooling. Disassemble the pump test coupling on site, which will affect the environment. After the pump test coupling is removed, the pump must be transported back to the assembly room to assemble the transmission gear. The whole process is cumbersome, and there are additional logistics, management and Operating costs;
