1. Bit Breakers The Bit Breakers are suitable to make up or break out the drilling bit during the oil well drilling and repairing operations. The Users should be chosen the bit breaker according to the size and model of the drilling bit. Feature:Improve support and retention Advantage:Manage the magnitude cutter loading and bit torque Benefit:Improved bit durability and directional responsiveness Advantage:Higher nozzle counts and/or fixed ports to best serve cleaning,cooling and cuttings evacuation requirements with available hydraulic flows.Allow for higher flow rates with minimal increase in pump pressure. 2. Detailed introduction to Bit breaker 1) Bit breaker is mainly used to screw on or off a rock bit to the bottom of drill string. 2) It can also prevent the rock bit from dropping into well hole. 3) The price of it is cheap and the use of it is safety and reliable. 4) It is easy to operate. First, the bit breaker is placed on well hole and then put the rock bit onto it. Turn it to screw on or off the bit by turnplate.
Automatic circuit breaker tester UPA-3 is designed for testing and ampere-second characterization of automatic AC current circuit breakers. The device allows registering the value of the supplied current and timing the automatic circuit breaker switching interval. Circuit breaker tester UPA-3 is a mobile device, which could be easily transported to a required testing location. Circuit breaker tester UPA-3 operates on the principle of varying the power in the primary circuit of the matching power transformer and, respectively, varying the output current, flowing through the automatic circuit breaker under the test. Power regulation could be done either through an external regulator (RNO or VR) or through a built-in thyristor controller.
