Hydraulic gear pump is suitable for conveying containing no solid particles and fibers, high temperature non-corrosive liquids, hydraulic gear pump medium temperature is 250 ℃, the viscosity of 5 to 1500 CST.When the gear rotates, the melt into the suction chamber two gear tooth, with gear running, the melt from either side into the discharge chamber, the gear meshing, again make tooth melt out of the discharge chamber and pressure to the export pipeline.As long as the pump shaft turns, the gear presses the melt toward the outlet side.Colui hydraulic gear pump placement mode and requirements are as follows:
I. requirements for hydraulic gear pump layout
1. For pumps arranged in the open air or semi-open air, the pump is generally perpendicular to the axis of the prime motor and the axis of the pipe gallery.
2. For indoor pumps, when the conveying liquid temperature is higher than the natural point or the conveying liquid is liquid hydrocarbon, they should be arranged in separate rooms with other pumps and separated by firewalls.
When the pump is arranged indoors, the requirement of motor vehicle maintenance is generally not considered.
The net distance between pump end or pump side and wall should not be less than 1.2 ~ 1.5m, and the net distance between two rows of pumps should not be less than 2m.Steam reciprocating hydraulic gear pump power side and pump side should be left with the position of extraction piston and rod.
When vertical pump is arranged under the pipe gallery or under the frame, the space required for installation and maintenance of pump body should be set aside at the top.
Space required for maintenance and inspection of various centrifugal pumps.When piping is arranged, at least one side of both sides of hydraulic gear pump should be set aside for maintenance.Other types of hydraulic gear pump maintenance inspection space required.
Ii. Hydraulic gear pump arrangement
1. Generally, the pump is centrally arranged in the lower part or side of the pipe gallery in the open air, or in the vicinity of miscellaneous suction equipment. The main advantages are good ventilation, convenient operation and maintenance.If the pump is arranged under the miscellaneous pipe gallery, the center line of pump outlet should be aligned, 0.6m away from the center line of pipe column.
2. The pumps arranged in semi-open air and semi-open air are suitable for rainy areas. Generally, the pumps are arranged under the pipe gallery and the ceiling is set on the upper part of the pipe.Or the pump is arranged on the lower floor of the frame, with the frame platform as the ceiling.According to the arrangement requirements of the subjapan hydraulic gear pump, the pump is arranged in single row, double row or multiple row.
3. The pumps arranged indoors are suitable for cold or windy sand areas, as well as special requirements of the process.
