Eight methods of high pressure regular cleaning of petroleum machinery

1. The high pressure of petroleum machinery should keep the appearance beautiful and tidy. It needs to be wiped and waxed frequently to remove water vapor in time to prevent rust. For the cold north, before the severe winter comes, the internal parts of the high pressure of the petroleum machinery should be disassembled and washed, and protected with protective sleeves to prevent the internal parts of the high pressure of the petroleum machinery from freezing and cracking due to accumulated water. 2. The high-pressure internal filter screen of petroleum machinery should be cleaned regularly and damaged and replaced. The net sleeve should be washed with gasoline and the dirt in the oil inlet of the oil pump should be removed. 3, the oil tank should be cleaned regularly to keep the oil clean. 4. The return valve adjustment screw on the pump is used to adjust the pressure of the pump, and then adjust the oil machine

What are the reasons for the high pressure corruption of petroleum machinery?

1. High pressure corrosion of petroleum machinery caused by polysulfide in petroleum Most of the oil in our country contains more polysulfides, in the process of oil exploitation, petroleum machinery and equipment are easy to be corroded by the polysulfides in the oil when they come into contact with the oil, and then produce a variety of polysulfides on the surface of the high pressure of petroleum machinery. In the process of high pressure operation of petroleum machinery, these polysulfides will bring a lot of unstable factors to petroleum machinery. In addition, mechanical equipment exposed to the air for a long time, the carbon dioxide and moisture in the air will react with the corrosion part of the mechanical equipment, and ultimately lead to the corrosion of the entire petroleum machinery and equipment.

Selection skills of high pressure profile control pump for petroleum machinery

In the high pressure of petroleum machinery, the use of high pressure profile control pump is very extensive. This is a kind of general-purpose mechanical equipment with a large number of wide range. It is not only used in the petroleum industry, but also used in other industries such as chemical industry, electric power metallurgy, mining, shipbuilding, agriculture, national defense and so on. However, in many industries, including the oil industry, the selection of high-pressure profile control pumps is often inappropriate, resulting in its operation in an unreasonable state, mainly manifested in low operating efficiency and waste of energy. Even because the selection is unreasonable, it can not be used, or it increases a lot of maintenance costs when it is used. It can be seen that the high-pressure profile control pump is selected when in use.

Main Causes of Failure of High Pressure Mud Pump in Petroleum Machinery?

There are three main reasons for the failure of the seal of the high-pressure mud pump of petroleum machinery: 1. When the sealing surface is opened to repair the high-pressure seal of petroleum machinery, 85% of the seal failure is not caused by wear, but has leaked before wear. When the sealing surface of the mud pump fittings is opened, the solid particles in the medium enter the sealing surface under the action of liquid pressure. After the sealing surface is closed, these solid particles are embedded in the surface of the soft ring, which actually becomes a "grinding wheel" and will damage the surface of the hard ring. Since the moving ring or rubber ring is fastened to the shaft, when the shaft moves in tandem, the moving ring cannot fit in time, so that the sealing surface is opened, and the sealing surface is closed with hysteresis.

Discussion on the Structure of High Pressure Mud Pump of Petroleum Machinery

Petroleum machinery high-pressure mud pump mainly consists of the following parts: (a) power end 1, pump casing and pump cover are made of steel plate welding. The bearing seat of the driving shaft and the crankshaft is an integral cast steel part, which is welded with the pump casing after processing, and annealed after welding to eliminate residual stress. 2. Driving shaft The size of the extended parts at both ends of the mud pump driving shaft is completely symmetrical. Large belt pulley or sprocket can be installed at either end. The supporting bearings at both ends adopt single-row centripetal short column roller bearings. 3. The crankshaft adopts forged straight shaft and eccentric wheel structure, and does not adopt the traditional integral casting crankshaft structure of three-cylinder pump at home and abroad. The castings are forgings and the whole is integrated.

What is the principle of supercritical water oxidation technology?

Supercritical water oxidation is an emerging skill in organic waste and wastewater treatment. 1, the simple process of supercritical water oxidation is the first, the sewage pump is used to press the sewage into the preheater for preheating, which is directly mixed with the usual circulating reactants to enter the reactor after the heating temperature is improved, and then the compressor is used to pressurize the air or oxygen into the reactor. Harmful organic matter and oxygen in supercritical water agile reaction to the complete oxidation of organic matter, such as organic matter concentration to meet, the heat released by oxidation is enough to heat all the materials in the reactor to supercritical condition, in homogeneous conditions to make organic matter reaction. The material separated from the reactor enters after cooling.
