Downhole tools for oil rigs include: stabilizers, scrapers, centralizers, etc.
The replaceable sleeve stabilizer are available with
two-piece and three-piece construction. The three-piece construction stabilizer
is made of a body and a centralizing body(refer to sleeve replaceable). The
advantage is that the sleeve can be changed quickly and easily after sleeve
hardfacing is worn-out. This kind of stabilizer is especially suitable for
working in directional well .
The working principle and usage instructions of the ice water machine
Author: Beijing Hengxing and Technology Co., Ltd. Source: http: //
Ice water machines are commonly known as chillers, freezers, chillers, chillers, chillers, water coolers, etc. Because of the different functions of applications in various fields, the name is also different. However, it has exerted tremendous power in the refrigeration industry (refrigeration equipment). The ice water machine, chiller, freezer, chiller, chiller, chiller, water cooler, etc. are all water cooling equipment, which can provide constant temperature, constant current and constant pressure cooling water equipment. The working principle is to first inject a certain amount of water into the water tank of the machine, and then cool the water through the refrigeration system, and then the low-temperature cooling water is sent to the equipment to be cooled by the water Pump, and the chilled water takes the heat away and then the temperature rises and then flows back to the water tank. , to achieve the effect of cooling. The cooling water temperature can be adjusted automatically according to the requirements. The long-term use can save water, which is the necessary equipment to ensure the normal operation of the user equipment.
Ice water machines are widely used in plastic Processing Machinery to mold cooling. Function: It can greatly improve the surface finish of plastic products, reduce the surface marks and internal stress of plastic products, so that the products do not shrink or deform, facilitate the demoulding of plastic products, accelerate the product stereotype, and greatly improve the production efficiency of plastic molding machines; At the same time, it is also widely used in CNC machine tools, coordinate boring machines, grinding machines, machining centers, combined machine tools and various types of precision machine tool spindle lubrication and hydraulic system transmission medium cooling. Function: It can accurately control the oil temperature, effectively reduce the thermal deformation of the machine tool and improve the machining accuracy of the machine tool.
Ice water machine installation instructions:
(1) Be sure to ground the ground of the machine to avoid electric shock accidents;
(2), do not press on the fuselage or place heavy objects;
(3) Whether the cooling water pipe is tightly locked and whether the cooling water is circulating;
(4) Whether the ice water pipeline connection is unblocked.
Instructions for use of ice water machine:
1. Before the ice water machine is turned on:
First check the water supply, cooling equipment (cooling fan or cooling tower), voltage, wiring method (the bottom line and the zero line must not be reversed), high and low voltage values ​​(mainly to see if there is any leakage of refrigerant).
2, ice water machine boot:
Power on line for 3-12 hours (the system will automatically preheat the compressor, especially in the north), start the unit (starting sequence: refrigerating pump - cooling pump "fan or water tower" - compressor), check the motor current is generally 1HP =1.2-1.6A, check whether the motor is running normally "mainly to see if there is any water leakage and noise."
3. The chiller is shut down:
Do not directly turn off the power supply. "The integrated control of the board is controlled by the stop button (key); the manual switch is used to turn off the compressor." The sequence of shutdown is the compressor-cooling equipment (fan, water pump, water tower,) - the freezing pump.
4. The ice water machine will not be used for a long time. Please pay attention to the following items:
(1) The evaporator, water tank, condenser, and pipeline water should be drained as much as possible.
(2) Close the valves of each pipeline.
(3), cut off the power supply (air switch, central control box, etc.).
(4) Do a good job of rust and dust prevention.
The above is the knowledge about the ice water machine shared by Beijing Hengxing and Technology Co., Ltd. We can only use it to the best of its knowledge if we understand this knowledge. I hope that this knowledge will help you in your future use.
