Centrifugal pump hydraulic loss impact loss, eddy loss and along the friction loss. First, the impact of loss Each pump has its own design flow, when consumed in the design flow conditions, the flow of the inlet is along the leaves into the impeller, so the impact does not occur with the leaves, the same outlet flow does not occur and The impact of the pump shell, then more efficient. However, when the flow deviates from the design condition, the flow direction of the flow should deviate from...
(1) Attention should be paid to the anomalous sound, vibration or abnormal signal of the monitoring system at any time. There must be a reason for this. If an abnormal phenomenon is found, the circuit diagram is immediately found and the diagram is taken. Careful observation is made as to whether the abnormal phenomenon is a temporary error . Assessment need not need parking treatment. All pressure, load, temperature, time, start, stop when it includes the possible causes of abnormal phenomena....
High pressure piston pump maintenance _ High pressure piston pump often appear in use a variety of problems, to bring a lot of trouble to life. Then how do we discover and eliminate these faults in time? High-pressure piston pump repair - can not start First of all, check the power supply situation: whether the connection is solid or not; whether the switch is in close contact; whether the fuse is blown; whether the three-phase power supply is equal or not.

Hydraulic pump work there are two kinds of power loss, a power loss is the volume loss, the other is a mechanical loss. 1, the cause of mechanical loss ① hydraulic pump work, the relative motion pieces, such as bearings and shafts, shaft and seal between the blade and the pump body wall between the mechanical friction, resulting in frictional resistance loss. This loss and the hydraulic pump output pressure, the higher the output pressure, the greater the frictional resistance loss. ②. Fluid...

On April 21, researchers at the Shengli Oilfield Oil Recovery Institute injected water into the ST3-8X567 injection well at Tuojiao Injection Station 28 to carry out the negative pressure relief plugging technology of the hydraulic jet pump . After the implementation, the formation liquid production volume was 25 cubic meters and the polymer 5 cubic meters M, played an immediate effect. Polymer injection wells in the old area because polymer macrophages flow in the reservoir hole difficult to...
Engines for commercial vehicles in on- and off-highway applications have to comply with increasingly stricter emission limits. Specifically in emerging markets such as China, Middle East and Africa, this requires the change from mechanical to electronically controlled injection systems. China-Lutong has developed a solution that not only permits new engines to be equipped with the Common Rail System. It also allows existing engines, which were originally designed for distributor or mechanical...
Car booster pump problems, through a comprehensive visual inspection found that no leakage of hydraulic piping, pump body and the direction of the phenomenon, the hydraulic fluid in the tank between the upper and lower limits, the drive belt tight and moderate, but the hydraulic oil was black There is a deterioration of the phenomenon. In the observation of oil surface, in addition to the hydraulic oil was found to be too dirty, it is also found in the flow of hydraulic fluid bubbles from time...
1. Install the pump first check the pump inlet and outlet flange seals and do any pipe deformation (best to replace the new), and should clean the inner wall of the oil pipe dirt, check the oil pipeline connections The sealing performance. 2. Check the motor shaft and bearing deformation and wear, such as the shaft swing phenomenon should confirm whether the shaft deformation or bearing wear and tear, prevent the motor due to affect the life of the pump. 3. Check the coupling for wear and tear....
Screw pump hydraulic anti-reversing technology is to prevent the conventional screw pump wells in the shutdown or card pump column reversal, resulting in off the rod, polished rod rejection bending, ground equipment damage and other issues of technology. Screw rod pump often shut down after the pole reversal phenomenon occurs, the pole of the internal storage of torsional potential energy and the oil pressure differential may lead to pole reversal. Sudden release of the sucker rod torque, by...
1. The axis of the pump and the axis of the motor to maintain a certain degree of concentricity. For gear pumps , the coupling between the pump's rotating shaft and the motor's output shaft must be non-coaxial. 1mm, the sleeve shaft coupling with different axial degrees shall not be greater than 0.05mm; for the vane pump, the general requirements of different axes shall not be greater than 0.1mm, and the flexible connection between the motor should be used; the same for the oblique...
Common failures in the hydraulic system can be grouped into four types: empty load can not be improved; heavy load can not be improved; slow speed and jitter accompanied by lifting phenomenon; when the joystick is placed in a neutral position, the implement drops rapidly. In the hydraulic system failure analysis, can be divided into two sections: the fuel tank, the pump for the first section, responsible for the oil supply and the low-pressure oil into high-pressure oil, the hydraulic system is...
1, is to manually rotate the coupling, should feel light, force evenly to identify the pump installed properly. 2, is to check the direction of rotation of the pump pump plate should be consistent with the direction indicated, shall not be reversed. 3, is to check whether the hydraulic system laxative loop, can cause full load start and stop, and even reduce the service life of the pump, and the motor overload. 4, is to check whether the safety valve in the system is set on the permit pressure....
Injection molding machine hydraulic vane pump common cause of failure and exclusion: Fault Cause / Troubleshooting A. No oil discharge 1. Rotary position fallacy (positive, counterclockwise) immediately stop, more positive motor rotation position. 2. Pump non-rotating motor power is returned, to confirm the coupling or key is corrupted. 3 pump shaft rupture, the rotation of the rotor does not rotate the trim pump to confirm the motor speed is too high, the core is aligned core 4. Suction tube...
1. Observe the relevant part of the "safe operating procedures motor". 2. Before starting the application of hand to promote continuous section, check the pump and motor installation is correct, with or without clogging. 3. Before starting should do the following: 1) Fix the outlet pipe, stop standing or placing objects in front of the outlet. 2) The pump body should be filled with water, no water idling. 3) Close the outlet pipe valve and pressure gauge cock. 4.

Gear pump hydraulic circuit function analysis 1, priority flow control Regardless of gear pump speed, working pressure or branch flow size required, the value of a flow control valve can always ensure the required flow of equipment work. In this circuit, the pump output flow must be greater than or equal to the required flow of the oil circuit, secondary flow can be used for it or back to the tank. Setting a flow valve (proportional valve) will be a combination of control and hydraulic pump,...
