1. Choose a reasonable solution (1) The shorter the distance between the outlet of the vacuum system and the inlet of the pump, the better; (2) The less the curve turns, the better; (3) The inlet pipe should be higher than the inlet centerline of the pump, Taibang export pipe should prevent factors that cause greater resistance, such as climbing on the export pipe, cornering at right angles, etc.;
Precautions when installing heavy oil pump
1. Choose a reasonable solution (1) The shorter the distance between the outlet of the vacuum system and the inlet of the pump, the better;
(2) The less the curve turns, the better;
(3) The inlet pipeline should be higher than the inlet centerline of the pump. The Botaibang outlet pipe should prevent factors that cause greater resistance, such as climbing on the outlet pipe, cornering at right angles, etc.
(4) The diameter of the matching inlet and outlet pipe should be the same as the diameter of the inlet and outlet of the product. If the vacuum system is small, the diameter of the inlet and outlet fitting pipe can be small, but not less than 70% of the diameter of the product inlet and outlet, and the diameter of the outlet should be Greater than or equal to the diameter of the inlet pipe;
(5) The bend of the pipeline should be smooth transition;
(6) The oil supply pipeline of the heavy oil transfer pump should be equipped with a valve to adjust the amount of oil input. The amount of oil input has an effect on the degree of vacuum. When adjusting the oil intake, the valve is controlled by observing the pointer of the vacuum gauge. The ultimate vacuum of SK-0.8 can reach -0.087. Under the working condition, because the pipeline is not completely sealed, the vacuum can meet the working demand at around -0.06. Botou Taibang Pump & Valve Manufacturing Co., Ltd. 2. When installing or repairing pipelines, avoid falling into foreign objects.
3, the joints of the pipeline should be sealed, there should be no leakage or oil leakage.
4. Install a vacuum gauge at the suction port of the vacuum device to control the change of vacuum.
5. When the vacuum reaches the limit, it will emit a lot of noise, called cavitation sound, and adjust the vacuum degree through the valve. When the vacuum is high, test the blasting detector, open the valve and let off the excess gas, and the cavitation sound immediately. It disappears and the valve is closed when the vacuum drops.
6. One of the important functions of circulating oil is to cool the heat generated when the heavy oil pump is working. When the oil temperature of the circulating oil exceeds 40 degrees, the degree of vacuum will decrease, and the cold oil will be replenished or replaced in time to reduce the circulating oil. Heat, the heavy oil pump on the fencing equipment uses iron drums to hold the circulating oil, and the oil in the drums is more.
