Circulating cooling water device applied to petroleum driller braking system and application method

Abstract

The invention relates to a circulating cooling water device applied to a petroleum driller braking system and an application method. The system comprises a water storing tank, a flow guide plate, a water supplementing loop, a water draining loop and a water returning loop, wherein a heat insulation board is arranged on the inner wall of the water storing tank, and the flow guide plate is arranged in the water storing tank; in case of pouring water into the water storing tank, a water source pipeline can be connected, and a seventh valve can be opened; if a pump A is used for supplying water, a third valve and a fourth valve are opened; if a pump B is used for supplying water, a fifth valve and a sixth valve are opened, a water source valve is opened, and the rest valves are closed; after a water pump is subjected to air exhausting, the pump A or the pump B is started, and a twelfth valve is gradually opened; when the water pouring is finished, the twelfth valve is closed, then the pump A or the pump B is stopped, and the rest opened valves are closed. The circulating cooling water device is low in manufacturing cost; a water storing part is manufactured from common steel and heat insulation material; the circulating water storing tank is free of extra heating in winter, so that the energy consumption can be saved; the water pump and a cooler are reasonably assembled and used, so that the cooling efficiency of the circulating cooling water can be greatly improved.

Description

technical field [0001] The present invention relates to an oil rig drawworks operation auxiliary device and its use method, in particular to a device and its use method for providing circulating cooling water for the brake system of an oil rig in a field operation environment with a large temperature difference between day and night or between seasons. Background technique [0002] The heat load generated by the braking system of the oil drilling rig needs to be exchanged and taken away by the low-temperature circulating water to ensure the normal operation of the braking system of the oil drilling rig. It is generally equipped with a device that provides cooling circulating water for the brake system, and the device has the function of cooling circulating water. In order to provide circulating cooling water in winter, summer or in an operating environment with a large temperature difference between day and night, and to prevent freezing and damage to the water supply storag...

AI Technical Summary

Problems solved by technology

[0007] 1. The coil needs a certain amount of thermal steam, external heat source, and laying pipelines. Not only will there be problems of heat loss and increased engineering quantity, but if the coil is used for a long time, it will be severely corroded or even leaked.

[0008] 2. Electric heaters also have hidden dangers of corrosion and leakage, and long-term use will consume a lot of power

[0009] 3. The cost of circulating fluid with water + ethylene glycol as the medium is high, and if there is leakage, there will be pollution and safety problems
