Hydraulic pump oil nozzle heating and throttling device

The utility model relates to a hydraulic pump oil nozzle heating and throttling device, which belongs to oil field drilling equipment and comprises a heating furnace, a combustor, a control center anda coil pipe, the coil pipe is divided into an upstream coil pipe and a downstream coil pipe which are connected through an oil nozzle, and the coil pipe and the oil nozzle are heated by the heating furnace through automation of the control center. According to the technical scheme, on one hand, the problems that due to throttling of the oil nozzle, the temperature of fluid is reduced, and hydrates are formed are solved; on the other hand, the combustion effect of the crude oil is improved by reducing the viscosity of the crude oil, and the ground power liquid heating requirement of oil fieldhydraulic pump oil testing and liquid discharging engineering winter construction is met. 本实用新型涉及一种水力泵油嘴加热节流装置，属于油田钻探设备，包括加热炉、燃烧器、控制中心和盘管，其中盘管分为上下游盘管由油嘴连接，通过控制中心的自动化制，由加热炉对盘管及油嘴加热。本实用新型的技术方案一方面解决了由于油嘴节流导致的流体温度下降，造成水化物形成的问题；另一方
