一、改装理由及效果;1979年以来,原地质部水文地质工程地质局设计并发放了一批测井车给各省水文队,极大地促进了水文测井工作的发展。该车是我国首次为水文测井专门设计的测井车,有不少优点,但也有一个比较重大的缺点,就是绞车采用液压驱动。由于液压元件不过关,绞车常出故障,液压元件的修理技术要求较高,野外队的修配车间和一般工厂都难以胜任,而原厂又远在千里之外。因此修理工作成了一件费时、费力,费钱的麻烦事。据我们的实践,在使
I. Reasons and Effects of Modifications Since 1979, a series of well logging trucks have been designed and distributed by the former Department of Hydrogeology and Engineering Geology to various provincial hydrological teams, which has greatly promoted the development of hydrological logging. The car is the first logging logging vehicle specially designed for hydrological logging in our country, and has many advantages. However, there is also a rather serious disadvantage that the winch is hydraulically driven. As the hydraulic components off, winch often fails, hydraulic components of the higher technical requirements for repair, field team repair shop and the general factory are not competent, and the original factory and thousands of miles away. Therefore, repair work has become a time-consuming, laborious, expensive trouble. According to our practice, in making
