L28/32 diesel engine parts L28/32A-rotor valve

The valve rotator is an important part of marine diesel engine accessories. When the diesel engine is working, the valve rotator causes the intake and exhaust valves to rotate slowly to prevent the combustion of the diesel engine at low load or overload operation. Stuck or burnt to death, therefore, the quality of the valve switch is related to the service life of the valve. For the inspection of the rotary valve, if there is no special inspection tool, only the appearance size can be inspected, but the performance cannot be inspected. For the user to inspect the performance of the rotary valve in the factory, the cost of purchasing the inspection tool The current inspection method is to test the performance of the valve switch on the diesel engine. Mark the valve stem. The diesel engine will be preheated to meet the requirements, and then run for a certain period of time, and wait until the diesel engine cools down. It takes a long time to measure the rotation angle marked on the valve stem, and requires many people to cooperate, which is time-consuming and labor-intensive.

In order to overcome the above-mentioned technical problems existing in the prior art field, a marine diesel engine valve switch detector is provided, which has high detection accuracy, convenient use and high detection efficiency.

The valve detector for marine diesel engines includes a base, a test bench, a reduction motor, a drive shaft, a cam, a guide cylinder, a guide bracket, a tappet, an oil pipe and a gas valve. The geared motor is installed on the base. The output end of the geared motor is connected to the drive shaft, and the drive shaft is connected to the cam. A guide bracket is set above the cam. The guide cylinder is connected to the tappet. The upper part of the guide cylinder and the lower part of the tappet are located in the guide bracket. A rocker arm seat, a spring and a nameplate are installed on the testing platform. A rocker arm is installed on the rocker arm seat. One end of the rocker arm is connected to a tappet, and the other end is connected to a valve. The spring is located below the valve. The nameplate is marked with a scale. The work can be completed by only one person, and there is no need to complete the inspection on the compact and small-space diesel engine, so the inspection is easy and accurate. The geared motor is used as the power source, and the energy consumption is low.
