What are the requirements for the selection of Rotary Drilling Rig Hydraulic Motor in China
Rotary Drilling Rig Hydraulic Motor in china has higher efficiency in medium and high pressure areas.
(1) Rotary Drilling Rig Hydraulic Motor in china has higher efficiency in medium and high pressure areas. When configuring the working pressure of the motor, taking into account its working life and power utilization rate, the motor of the rotary drilling rig should be operated near the medium pressure as much as possible.
(2) Rotary Drilling Rig Hydraulic Motor in china has higher working efficiency at medium speed.
(3) Decrease the motor displacement, and its efficiency will decrease, especially at low displacement and low speed, the efficiency is lower, and the working capacity is very weak. The motor can only guarantee high-speed operation when it has a large displacement. When controlling the displacement of the motor, the working condition should be: when the load increases, the motor has a large displacement and low speed, and when the load decreases, the motor has a small displacement and high speed. Try to avoid making the motor work at small displacement and low speed, and avoid the minimum displacement ratio of the motor below 0.3.
(4) In the actual design process, the motor and the pump have a matching relationship in terms of displacement. Generally, the displacement of the motor should be 1.2 to 1.6 times the displacement of the pump. Otherwise, the system pressure will be too high, the speed fluctuation will be too large, The motor speed is too high, the engine stalls and the operating efficiency is low. Generally speaking, the larger the motor displacement, the better, but a larger motor displacement will make the manufacturing cost prohibitive.
