SHOCK ABSORBER
SHOCK ABSORBER
Type SJ
Shock Absorber Type SJ should be connected with the drilling string close to the bit. It can reduce or absorb both longitudinal and circumferential vibration of the drilling string in drilling operations. It can achieve the optimum combination of drill pressure and drill speed, reduce the drilling cost and promote the drilling efficiency.
Hydraulic Shock Absorber Type YJ
Hydraulic Shock Absorber Type YJ should be connected with the drilling string close to the bit. It can absorb or reduce axial vibration and thrust load of the drilling string, and have a good result for prolonging the service life of the bit and protecting the drilling tools as well as surface equipment.
Mechanical-Hydraulic Shocker Absorber Type DHJ
Mechanical-Hydraulic Shocker Absorber Type DHJ is a new type double-acting shock absorber. It absorbs the pulsation and shock from drill tools by compressing spring and silicon oil to store the energy. This shock absorber has advantages of good maintainability, bearing high load and long service life.
