150 secure the reliability of hydraulic drilling rig


Validation study with two parts. In the test mainly for indoor hydraulic system functions, torque and speed, propulsion and speed, power and back up the speed dial, cooling and electrical parameters of the load testing and other projects running studies to investigate whether to optimize the design requirements parameter index and running requirements. Verify that the primary application of a comprehensive drilling capacity and speed, long-term work in the state of parts reliability and durability, the whole job stability and directional drilling and other research. 4.1 Laboratory studies ZYG a laboratory test rig 150 is a coal research engineer 1998 6 COALEiEnNo61998 rig in Chongqing branch of laboratory safety, experimental 8m/rain; hydraulic system is the cooling function test rig in system, the hydraulic system pressure range 3MPa to system pressure 7.5MPa (according to test rig in the pit is 10.5, MPa (design system rated working pressure), often running from 3MPa system pressure is basically no more than this value),[Linkleri görebilmek için üye olmalısınız.

Test results: When the system pressure 10.5MPa, drilling conditions, the measurement of water flow through the cooler, torque testing machine in the whole of 679.59N. 1171, the output speed 104r / no oil leakage in the phenomenon. rain, the actual motor input power 14.23kW, propulsion laboratory test data: one for the new ZYG 52.67kN, aside from the force of 42.66kN, the normal speed of 150 rig to promote the optimal design of indicators, degree than is 1.39m/min,[Linkleri görebilmek için üye olmalısınız. Üye olmak için tıklayınız...], back to normal speed 1.72m/rain, fast and some 150 rigs and better performance. Two kinds of speed drilling advance speed 12.1m/min, fast backward speed 14. Test data in Table 1. . The main technical indicators are relatively bad a project to build working pressure drilling torque transfer speed dial from the drilling thrust force sent to build the largest orchid Zhu Tese f% 1 (NmJ (r / rain) (threat) (n) (kN) () ( r, m) of water (u Ⅱ blood) equilibrium Q () The One Note ① efficiency refers to the power output of the first rotation with the motor power for cutting part of the output power ratio; share of power for drilling is not, thus a feast occasion rig efficiency This value is high; ② f .1 for the lower to increase 4.2-proven research - in the second mine Songzao Bureau of Mines for three months to get through the ZYC, a 150-type test rig applications (practical and effective application of time-day) The total drilling 78, 6km footage and more, the average single-class footage 55.5m, the highest class footage of about 130m, an average of 13 footage 166.4m, up 13 footage 365.1m, 2 holes of the drain hole depth greater than 65m measured small deviation of the final hole was 0.5m,[Linkleri görebilmek için üye olmalısınız.

(2) Hydraulic system: significantly reduce transmission losses, transmission efficiency, nearly 10%; the cooling effect of increased water consumption by 23%, the cooling speed, good sealing performance, fuel consumption by about s7%; system is reliable, no component damage (3) drill: drill pipe strength, stiffness and wear resistance greatly improved, comprehensive loss decreased 96.92%; drill cutting to improve,[Linkleri görebilmek için üye olmalısınız.
