CE Approved Water Well Drilling Rig Mud Pump
Brief Introduction
BW160/BW200/BW250 Drilling Rig Mud Pump are mainly used for irrigation agricultural machinery.the main characteristic is the high pressure,lift much,less engergy consumption,easy operation,high quality and duarable,easy to move,especially for mountain terraces of irrigation.
They are also the main equipment of the geological survey,the main role in the process of core drilling boreholes is to supply fluid(mud or water),making it circulate during drilling and carry rock waste back to the ground,in order to achieve and maintain the bottom hole clean and lubricate drill bits and drilling tools with cooling.
BW-250 Drilling Rig Mud Pump is equipped with drilling rigs to drill holes with mud. During drilling mud pump pumps slurry to the hole to provide coat to the wall, to lubricate the drilling tools and to carry the rock debris up to the ground. It is applied to geological core drilling and prospecting drilling with depth less than 1500 meter.

What is the reason for the high oil temperature in the drill
The high temperature in the drilling rig is generally divided into the high temperature of the gearbox, the high temperature of the hydraulic oil, and some are the high temperature of the engine cooling liquid. In fact, the reason for the high temperature of the gearbox is very simple. The main reason is that the size and shape of the bearing or gear and housing are not standard or the oil is unqualified. Now let's give you a detailed analysis.
Hydraulic oil temperature is too high:
First of all, the temperature of hydraulic oil is too high. According to hydraulic theory and maintenance experience in recent years, the main reason for the high temperature of hydraulic oil is too fast heat generation and too slow heat dissipation. The oil inlet pipeline and hydraulic oil tank of the hydraulic pump are not sealed tightly, the oil inlet filter element is blocked, the hydraulic system pipeline is not unblocked, and the internal leakage of the hydraulic pump will cause a large amount of heat to be generated in the hydraulic oil, so that the temperature of the hydraulic oil will rise rapidly due to excessive heat generation.
The internal channel of the hydraulic oil radiator is blocked, the external dust of the radiator is too large, the wind force is not enough, and the hydraulic oil does not pass through the hydraulic oil radiator, which can lead to the high temperature of the hydraulic oil due to the slow heat dissipation
