Matters needing attention in the specific use of the residual oil pump

In order to ensure the good value and contribution of the residual oil pump in use, the following requirements should be noted in the specific use of the residual oil pump:

1. Disassemble the residual oil pump and pay attention to the clean working surface. The oil should be well filtered during operation.
2. The slag pump is equipped with the locating pin of the oil distribution plate and the stator. The blade, rotor and oil distribution plate are not reversed. The suction part of the inner surface of the stator is most likely to be worn. If necessary, it can be flipped over to make the original suction zone change. Continue to use for the discharge area.
3. The management points of the residual oil pump need to be protected from dry run and overload, anti-intake air and excessive suction vacuum.
4. When the shift of the residual oil pump is changed, the suction and discharge direction also changes the vane pump to have a specified steering, and the reverse is not allowed. Because the rotor groove is inclined, the blade is chamfered, the bottom of the blade is connected to the oil discharge chamber, and the throttle groove and the suction and discharge ports on the oil distribution plate are designed according to the predetermined steering. Reversible vane pumps must be specially designed. The residual oil pump pays attention to a certain steering function in the specific use, and performs good control in the actual steering, and the direction is not reversed.
5. If the gap of the residual oil pump blade in the groove is too large, the leakage will increase. If it is too small, the blade will not be able to expand and contract freely, which may result in malfunction.
6. The temperature and viscosity of the residual oil pump oil should generally not exceed 55 ° C, and the viscosity should be between 17 and 37 mm 2 / s. If the viscosity is too large, oil absorption is difficult; if the viscosity is too small, leakage is serious. The residual oil pump is based on the LC type pump. In order to solve the problem of conveying asphalt and condensed oil, the outer surface of the pump casing or the end cover is insulated, and the working chamber of the pump is insulated by steam or heat transfer oil. Continuous work and intermittent work provide convenience and good condition.
