Price List of Single Stage Gear Pump

When assembling the sealing components of gear pumps, in hydraulic systems, manufacturers generally consider that the impact of temperature rise on stainless steel gear pumps can easily cause the gear pump to lock and the shaft to be held. When assembling the sealing components of gear pumps, stainless steel gear pumps generally transport more acidic and alkaline media. gear pump

In fact, this material combination is completely suitable for conveying lubricating media. Whether the sealing components are poorly stored or naturally aged and deteriorated, due to the high thermal expansion coefficient of 304 stainless steel material, manufacturers generally consider that the impact of temperature rise on the assembly of stainless steel gear pumps can easily cause the gear pump to lock and the shaft to be trapped. Lubricating oil with a temperature below 300 ℃, the gear pump has a simple and compact structure. Stainless steel gear pumps are mainly used in lubrication systems of various mechanical equipment to transport lubricating oil. The main reason for choosing stainless steel gear pumps is due to insufficient understanding of the medium conveyed by the pump. Conventional stainless steel gear pumps generally use 304 stainless steel material for the pump body. Stainless steel gear pumps mainly consist of gears, shafts, pump bodies, safety valves, and shaft end seals. Due to the high thermal expansion coefficient of 304 stainless steel material, it should be confirmed whether the sealing ring is purchased from non-standard manufacturers. The running parts inside the pump are lubricated with the medium they transport, suitable for conveying media with viscosity ranging from 510-6 to 1.510-3m2/s (5-1500cSt), especially when conveying media with no lubrication or poor lubrication.

When disassembling and reassembling the gear pump transmission device, first ensure that the teeth of the movable claw coupling and the fixed claw coupling are in full meshing position. Then, with the two fixed bolts on the positioning plate loosened but not unscrewed, insert the positioning pin on the engagement lever assembly into the rear of the positioning plateGear Oil PumpIn the hole on one side. If the long slot on the positioning plate has been turned to the limit and the positioning pin still cannot be inserted into the hole, the engagement lever assembly needs to be reinstalled, the spline fitting position needs to be changed, and after adjustment, the two positioning plate fixing bolts and the engagement lever assembly fixing bolts need to be tightened. Finally, the engagement lever assembly should be repeatedly pulled several times, and the movable claw coupling should slide freely. From the inspection hole, the teeth of the two couplings should be fully engaged at the engagement position, and fully disengaged at the separation position.

Overheating of the motor is a common problem that occurs during the operation of gear pumps. The specific analysis and testing are as follows:

1. Scope of use (flow rate, head) exceeds the design requirements of the gear oil pump: select the appropriate motor according to the series spectrum

2. Medium density exceeds gear oil pump configuration motor: Install a suitable gear oil pump motor

3. If the packing gland is pressed too tightly or the mechanical seal spring is adjusted too tightly: readjust the compression amount of the gland or mechanical seal spring

4. Poor assembly quality of the pump, with friction or motor not concentric with the pump shaft: Check the assembly quality and eliminate assembly faults.
