LC Roots pump range of applications: for conveying temperature not higher than 140 ℃ of crude oil, sugar, starch, yeast light alkaline liquid. For high viscosity, high concentration, high consistency of suspended solids or impurities in the media. LC Roots pump structural features: This series Roots pump consists of pump body, pump cover, shaft, gear, rotor, packing, gland and other components, the Roots pump with belt drive and gear reducer drive in two forms, Can be reversed, the shaft ends with a skeleton oil seal, the middle with a return device to prevent air intake or oil spills. Roots pump defects Introduction: 1, the oil pump insufficient or no oil pressure phenomenon: the working device to enhance slow, when lifting trembling or can not be improved; tank or tubing bubbles; lift hydraulic system issued a "jack, jack" Sound; tractor just start working device can be improved, work for a period of time after the oil temperature rises, the slow increase or can not be promoted; light load can be improved, heavy load can not improve the telescopic stage. Fault causes: (1) hydraulic fuel tank The surface is too low; (2) did not use the hydraulic oil according to the season; (3) the inlet pipe was seriously blocked by dirt; (4) the oil pump gear seal damage, the air into the hydraulic system. 2, pump internal parts wear pump internal parts wear will cause internal leakage. Among them, the leakage area between the floating bushing and the gear end face is large, which is the main part of the internal leakage. This part of leakage accounted for 50% of the total internal leakage of about 70%. The wear and tear of the lost circulation gear pump volumetric efficiency decreased, pump output power is much lower than the input power. The loss of all the heat into the heat, it will cause the pump overheating. If the combination of flat compression, due to work floating sleeve will be a small amount of exercise caused by wear and tear, resulting in slow or can not enhance the farm tools, such a floating sleeve must be replaced or repaired. A rotary Roots oil pump, an oil pump housing, a back cover, a gear box body, a bearing cover, a bearing gland, a driving shaft, a driven shaft, a rotor, a transmission gear, a driving shaft and a driven shaft sealing device, The box body 3 is an annular body with a closed body as a whole. The driving shaft and the driven shaft are respectively and rotatably connected to the left and right ends of the gear box through a bearing, a bearing gland, a seal, a bearing cover, and two intermeshing The transmission gear are respectively mounted on the right end of the drive shaft and the driven shaft in the gear box body, a side end plate is arranged on the right end side of the pump housing, an outer ring connecting sleeve is integrally arranged on the right end plate of the pump housing 1, A shaft sleeve matched with the driving shaft and the driven shaft, a right end of the pump casing is fixedly connected with a left-end butting bolt of the gear box body through a connecting sleeve, two cooperating rotors are respectively fixed with a driving shaft and a driven shaft The shaft end and the back cover are fixedly connected with the left end of the pump casing through a bolt, respectively, a driving shaft and a driven shaft sealing device are respectively arranged in the shaft sleeve on the right end of the pump casing, and on the right driving shaft and the driven shaft of the sealing device Fixed with a rejection Rings, the coupling sleeve is formed a lumen in the inner structure of the right end of the pump housing, between the inner cavity and the pump body is provided with an oil inlet communicating with the catheter. Roots pump is always in working condition, the relief valve is adjusted to a certain pressure, when the pump inlet pressure exceeds the regulation pressure, the relief valve overflow, the inlet pressure decreases; when the inlet pressure is too low, the pump to the pressure tank oiling , So that the import pressure rose to regulate the pressure. The role of two accumulators is to avoid the import and export pump pressure fluctuations, to ensure that the import and export pump pressure to meet operating conditions. When the Roots pump to do the stroke movement, the electromagnetic switch is open, the gas through the one-way valve into the pump, when the polished rod contacts the upper limit switch, the electromagnetic switch is closed, the gas barrier, when the pump down stroke. Since the establishment of the company, with the strong support from all walks of life colleagues and customers continue to grow and develop, with multiple high, refined, sharp equipment and the realization of CAD-aided design and information management. Company well-equipped, advanced design, production and testing means complete, strong technical force, with strong research and development capabilities. All members of the company determined to science and technology as the guide, in good faith for the purpose, as the fundamental quality, customer-God, excellence, the pursuit of eternal. When the polished rod touches the down stroke switch again, the electromagnetic switch is opened and the gas path is opened, and the gas is supplied to the oil pump again. The single-phase flow test device is mainly composed of a power cylinder, a plexiglass pump cylinder, a plunger and a hydraulic control system. It is the core part of the pump simulation test device. Its most prominent feature lies in that the plunger is driven up and down by the hydraulic control system It has the characteristics of stable travel, rapid reversing of bitumen heat pump and complete simulation of underground working conditions. It can simulate various working conditions in underground wells and the flow of liquid in a pump.
