Frequently Asked Questions for Reciprocating Institutions 1: What are the components of this reciprocating mechanism? The reciprocating mechanism includes a geared motor, an adjustable speed power supply, and a reciprocating mechanism. The equipment is installed and shipped, and you can go back and plug in the 220v household electricity to run. 2: Reciprocating mechanism stroke 3cm~15cm (can be adjusted freely) 3: The number of times of reciprocating expansion and contraction per minute The option marked in the option is the maximum speed of the motor with no load. For example: 24v90rpm, which means: the fastest can be stretched 90 times per minute under this voltage. (Through the speed control power supply, you can arbitrarily adjust the speed you need within the maximum speed) 4: How big is this push and pull? The push-pull force is mainly powered by the motor. The smaller the stroke, the greater the thrust. For details, please refer to the test data below. 24v stroke 4cm, thrust about 10kg 24v stroke 6 cm, thrust about 7 kg 24v stroke 8 cm, thrust about 5 kg 24v stroke 10cm, thrust about 4kg 24v stroke 12cm, thrust about 3kg 24v stroke 15cm, thrust about 2kg (The above parameters are tested in a flat state, there may be a little error in different use environments, please be aware!)
