Asphalt axis arc pump: a new design, advanced structure and reasonable. It is through the pump body to form a closed seal oil chamber volume changes to achieve the media delivery, sealing oil body and pump wear and tear, long service life. The pump body is provided with a jacket to ensure the flowability of the asphalt by means of heat transfer oil. The dynamic seal of the shaft is made of high temperature wear resistant packing, and the sealing effect is good. The pump is ideal for high viscosity media such as asphalt, conveying and storing equipment.

1. Structural features and uses
Asphalt shaft arc pump in the spindle rotation process, by the spring of the spring so that the seal ring and the pump shell line contact, to achieve the oil chamber volume from small to large, the oil chamber volume from small to small, to achieve the purpose of transmission media, Smooth, low noise.
In order to improve the efficiency of the pump, the tight seal around the rotary dynamic seal with special filler, high temperature wear resistance, good sealing effect, the lower part of the pump and the end of the set of thermal oil storage and flow space, the shaft arc pump heating, Pump normal operation, easy to transport media.
Asphalt shaft arc pump structure with cycloid reducer through the coupling directly with the active pump shaft connection. Pump shaft support at the use of oil-free bearings, installation, easy disassembly, without regular filling.
Asphalt shaft arc pump used in asphalt mixture mixing equipment in the liquid asphalt transport work, but also asphalt plant (station) asphalt transport, canning, discharge, spraying the ideal equipment, but also for other high viscosity media.

4. Installation and use
The base is placed on the base surface or on the surface of other components with 4-M16 × 220 anchor bolts. M27 × 2 thread on the upper surface of the pump cover is connected with the hot oil outlet, the M27 × 2 thread on the lower surface is connected with the hot oil inlet, and the M27 × 2 thread on both sides of the pump body is connected to the inlet and outlet piping of the hot oil.
This axis of the pump for the two-way pump, import and export lines can be arbitrarily connected, the motor wiring should pay attention to the pump shaft steering and import and export lines consistent.
In order to prevent high-temperature heat transfer oil for a long time through the shaft arc pump, so that the air chamber, can not work. When installing the arc pump, please contact the conductor in parallel.
Before the pump starts, open the shut-off valve, close the shut-off valve B, so that the heat transfer oil through the shaft arc pump sandwich, asphalt melting, and then start the motor, then close the valve, open the valve B, so that the heat transfer from the slip road.
Adjust the tightness of the dynamic seal of the pump shaft gland so that it is flexible and does not leak.
5. maintenance
5.1 regularly check the operation of the pump, with particular attention to the dynamic seal is hot and oil leakage, in order to timely adjust the sealing gland pressing degree.
5.2 often clean the pump's appearance and around, so that the normal operation.
