Double gear pump manufacturer

Double gear pumpIt means connecting two gear pumps in parallel, which can supply oil separately or together. Generally, twin pumps use vane pumps, one is a small flow high-pressure pump, and the other is a large flow low-pressure pump, which can be connected in parallel to meet the different needs of the system.

Dual gear pump=two oil outlets

The function of a dual pump is the same as that of a single pump. Its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, referring to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps, and plunger pumps.

Gear pumps are of relatively good quality and have a certain special application range among all gear pumps. However, stainless steel pumps may also experience unexpected malfunctions during operation, such as shutdown. It is necessary for us to analyze the main reasons for the shutdown of the gear pump, so as to avoid unnecessary damage to the gear pump in the future.

1. The parking of the gear pump should be carried out according to the technical specifications of the equipment. After parking, the gear pump should be turned half a circle every 20-30 minutes until the temperature of the gear pump body drops to 50 ℃.

2. Pumps that transport media that are prone to crystallization, solidification, and precipitation should be prevented from clogging after the gear pump is stopped, and the pump and pipeline should be promptly flushed with clean water or other media.

3. After the gear pump stops running, the inlet valve of the pump should be closed, and the valves of the auxiliary system should be closed in sequence after the gear pump cools down. Drain the accumulated liquid in the pump to prevent rust and frost cracking.

4. When the gear pump is stopped, if there are no special requirements, the pump should be filled with liquid regularly; The suction valve and discharge valve should be kept in a normally open state; For low-temperature pumps using double end mechanical seals, the liquid level controller and the sealing liquid in the pump sealing chamber should maintain the grouting pressure of the pump.

During the operation of the dual gear pump, if it is found that the clearance between the pump shafts is too small, it is necessary to effectively adjust the straight spacing of the shafts to ensure a safer and more effective operation. In addition, during the operation of the rolling needle, if it is not very flexible, it is necessary to replace the rolling needle inside the bearing. After all, it is particularly normal for components to wear out after long-term operation, and everyone can pay special attention to it.

During the operation of a dual gear pump, if the coupling between the pump body and the motor is not concentric enough, the best solution should be to adjust the concentricity in a timely manner to reduce the occurrence of errors.

After running for a period of time, any device product will encounter a series of problems. At this point, as a user, the most scientific and reasonable way should be adopted to solve the problem, which is the key to ensuring normal use. During operation, if the double gear pump is used improperly, it is also prone to related problems. Using appropriate methods to adjust it is still a trustworthy foundation.

Not only that, if the pressure valve malfunctions during operation, it is necessary to check whether the spring inside the valve is lacking elasticity and whether there are any related pollution blockages. This is the key to ensuring the quality of use and achieving upgrades.
