I believe everyone is familiar with the valve worm gear box, but how does the valve worm gear box achieve long life and stable performance?
 It is recommended that the worm gear box needs to be tested for performance. The worm gear box is a transmission mechanism with a worm gear and worm structure inside, which is widely used in the construction machinery industry.The advantages of the worm gear box are compact structure, stable operation, low noise, and reverse self-locking.The performance of the worm gear box needs to be tested before it is put into use.What performance tests are required for worm gearboxes?
1 The meshing performance test tests the overall rotation, requiring no jamming, flexibility, and proper meshing clearance.
2 Insulation resistance test: Under normal temperature and relative humidity less than 80%, the insulation resistance of the energized part is required to be greater than 20MΩ.
3 No-load test conditions: at rated speed, forward and reverse operation should be no less than 1h;
Testing requirements:
1) Smooth operation, no impact, no abnormal vibration and noise;
2) There is no leakage at the seal and joints;
3) No jamming, unsmooth movement, etc.;
4) Whether the transmission part is normal, whether the connecting parts and fasteners are loose;
5) There is no abnormal noise, the temperature will not rise too high, and there is no oil leakage. The test noise should be less than 70 decibels.At 1h;
4 Load performance test Test time: 2h and above after oil temperature balance;
The test requirements are the same as the no-load test.
How to make use of the valve worm gear box operation should pay attention to the opening and closing direction of the operation should be closed clockwise, the opening and closing operation end of the tongue and groove and tenon size should be standardized, facing the ground, so that people can directly operate from the ground.The opening tightness of the valve gearbox can be displayed by the indicator needle. When selecting the material of the indicator needle, if the working condition is good, choose stainless steel plate, otherwise choose painted steel plate instead of aluminum; it should be eye-catching. , Stable and firm.Improve the use efficiency and time of the control valve.
How to give full play to the efficiency of the worm gear box, according to the closing pressure of the valve, calculate the unbalanced force and determine the structural size of the valve and pneumatic actuator to ensure sufficient output power.At the same time, determine the flow rate for sealing.In the use of valve worm gear box mechanical products, we must pay attention to how to operate correctly, and improve the efficiency of the product on this basis. This is the benefit we hope to achieve when using any mechanical product.
Secondly, based on the characteristics of the sealing points of the valve drive gearbox, rubber seals and hydraulic rubber seals in contact seals are generally used.
