  1. There are two types of high-pressure pumps commonly used in oilfield water injection pumps, namely centrifugal pumps and plunger pumps. In terms of pressure, a single-stage centrifugal pump cannot meet the requirements of this design, but it can be realized by multi-stage combination. The plunger pump can meet this requirement, but in terms of flow, the plunger pump can only meet the design requirements through multi-cylinder combination, while the centrifugal pump can use the flow of a single impeller. From the structural analysis, even if the centrifugal pump adopts multi-stage combination, it has the advantages of small size and light weight. The plunger pump (in the case of multiple cylinders) has a large volume and a high weight. In terms of performance, the centrifugal pump can use the more popular mechanical seals, so its leakage is small and the efficiency is high. The plunger pump has serious leakage, especially under high pressure, and its transmission mechanism is not stable under high pressure. From the analysis of the medium, if the transported medium is clean water, it is more suitable for both pumps, but its leakage is larger than the plunger pump. Of course, if the medium (such as mud) with high viscosity or more impurities is transported, the mud plunger pump is still used in the oil field.

    Assembly of axial piston pump

    Installation of axial piston pump (1) Before installation, all parts or components to be installed shall be checked again and recorded. (2) Deburring all parts, especially the sharp corner. (3) All parts should be carefully cleaned before installation to prevent impurities, dust, dirt, etc. from mixing into the outer surface of each cooperation room in the pump, so as to avoid scratching the smooth appearance of each cooperation part. (4) When installing, the force ring should be struck. If it is necessary to strike, the hammer should not be used to hit the parts directly. Instead, it should be padded by the central object (such as copper rod). (5) During installation, the steel ball of centering tension spring should be prevented from falling off. The steel ball can be coated with cleaning grease to make the steel ball stick to the inner sleeve of tension spring or return plate before installation. Otherwise, if the steel ball falls into the pump during installation, other parts in the pump will be damaged during the operation, so that the pump can not be repaired again. Pay attention to this. Part of the pump port surface figure (6) there is a pin on the connecting surface between the pump body and the port plate, which should not be pulled out under normal circumstances. If the end face of the valve plate is pulled out due to grinding, attention should be paid to the accurate orientation of the locating pin to the pin hole on the pump body during re installation. If it is installed incorrectly, it will not be able to absorb oil normally. As shown in figure x, if the hydraulic pump works normally (according to direction a), it is necessary to install the positioning pin in hole 1; if the hydraulic pump works in reverse direction (according to direction B), it is necessary to install the locating pin in hole 2; if the hydraulic pump is required to be used as a hydraulic motor, the locating pin is necessary to be installed in hole 3 regardless of forward rotation or rotation. (7) After the variable head is installed, it should be adjusted within 0 ° to 21 ° and the final setting angle of variable head should be 20 ° 30 ′ and a layer of clean machine oil should be coated on the surface whose surface roughness meets the requirements. (8) When tightening the screw, the screw should be inserted symmetrically and evenly under force, and the pump shaft should be rolled by hand at the same time to ensure that the rolling is sensitive and stable, and there is no difference between the weight and weight.

    Micro air pump

    Micro air pump The essence of vacuum adsorption of micro vacuum pump: after the micro vacuum pump is powered on, the pressure difference between the negative pressure generated at the suction port and the external atmospheric pressure is used to firmly absorb the object through the contact elements such as suction cup, so as to play the role of hanging, fixing and moving objects. The next process of vacuum adsorption is the release of the object after being absorbed. When it is necessary to release the absorbed object, the pump must be shut down first, and do not continue to vacuum. After the pump is shut down, the object may not fall off immediately, because the pump has a certain pressure holding capacity, and the vacuum will continue to maintain for a certain period of time (the length of time depends on the air leakage of the system). However, the actual situation is that the current dual-purpose micro air pump, micro vacuum pump and so on, including domestic micro air pump, micro vacuum pump and most of foreign micro air pump and micro vacuum pump, because of the internal process principle and other reasons, only allow gas to flow from the air inlet to the exhaust port in one direction, and vice versa. It is not simple to reverse the motor can change the direction of the air flow, to meet the requirements of the release object. CL Sereis Cone Liquid Ring Vacuum Pump Roots Blowers Roots Vacuum Pump
