Hydraulic Gear Pump Fault Analysis and Solutions

Posted on

During the working process of hydraulic gear pump, there are often small flow, no oil absorption, low pressure, big noise, oil leakage, overheating, abnormal operation of oil pump or bite as these faults may be Hydraulic gear pump efficiency greatly affected, then the hydraulic gear pump failure analysis and the corresponding solutions are introduced. Hydraulic gear pump failure analysis and solutions 1, gear pump does not absorb oil or traffic Glitch analysis: (1) oil absorption position is too high or oil level is not enough. (2) gear pump top circle and the pump body bore radial clearance is too large, gear side and front and rear cover end clearance too large. (3) gear pump lax. The solution: (1) fill the oil tank to reduce the suction position. (2) replace the pump body. (3) Replace the sealing element and fasten the connecting piece. 2, the lack of pressure Failure Analysis: (1) gear pump radial clearance and axial clearance is too large, of which the impact of the gap greater. (2) Teeth crack, or a leak. (3) oil viscosity is too high or oil temperature is too high. Solution: (1) replace the pump body. (2) If the leakage is in the pump body and the pump cover plus pad, fastening the connector, if the pump is cracked, you should replace the pump. (3) 20 oil is suitable for 10 degrees -50 degrees temperature work, 3, vibration noise is too large Fault analysis: (1) gear error or two gears axis is not parallel. (2) gear pump inlet pipe diameter is too small. (3) clogged filter, or high speed. The solution: (1) replace the main precision gear to ensure that the two gear axis parallel. (2) replace the larger diameter of the inlet pipe. (3) Clean the oil filter or reduce the speed. The use of hydraulic gear pump can not be smooth, even if the price is high, even the best quality hydraulic gear pump may have a fault occurs, the failure will affect the hydraulic gear pump effect, which is inevitable . Hydraulic gear pump after years of development, the probability of failure has been gradually reduced, but the failure of the situation still exists to find a suitable solution requires more work experience and accumulation.

Building waterproofing application polyurea coating system

Polyurea Waterproof Coating is not a new technology. In fact, it has been in existence for nearly 30 years. Polyaspartic Waterproof Coating are used as waterproof and durability protection materials in many infrastructure projects due to their excellent performance characteristics. . Polyurea coatings are the most advanced material systems for waterproofing and protective coatings, but the technology is based on the reaction of isocyanate components with amine mixtures. The isocyanate can be an aromatic or ester family composition. The reaction is very fast and is completed in a few seconds. Therefore, specialized mixing and application equipment and professionals are required, and the cost is very expensive. This advanced material system is difficult to spread to various fields.


Based on this status quo, UMS has developed a set of simple, efficient and durable UMS-AUPT brushed polyurea waterproof protective material system based on polyurea coating for nearly five years, and has obtained many building waterproof projects at home and abroad. Actual inspection and application. The company from the resin to the coating, all independent technology development, and independent production.


The advantages of UMS-AUPT brushed polyurea waterproof protective material system

1. Can be brushed by hand, rolled, and airless if necessary. Construction is fast and flexible. It can be painted on any curved surface, inclined surface and vertical surface without sag.

2. No solvent, no VOC emission, environmental protection and energy saving; humidity and temperature have little effect on the construction process.

3. Advantageous physical and chemical properties, such as tensile strength, elongation, flexibility, wear resistance, aging resistance, corrosion resistance, etc.

4. High-strength coating, high elasticity and no seam are top-grade waterproof materials with excellent performance.

5. High adhesion and durability to various substrates such as steel, wood, glass, ceramics and concrete. Does not crack and does not fall off.

 

UMS-AUPT polyurea elastomer waterproof coating system is mainly in the following construction fields, with absolute technical advantages and comprehensive cost advantages.

1. Waterproof for Roof  / bridge deck.

2. Waterproof For Pool  /water park is sealed

3. Reservoir / Pond Waterproof Coating
