During the use of the plate vulcanizing machine, it is found that the gear pump is not supplied with oil and can be inspected from the following two points: 1. Check if the direction of rotation of the gear pump is correct. The gear pump has left and right rotations. If the direction of rotation is incorrect, the pressure oil formed by the volume difference generated by the internal gear meshing will cause the oil seal to be damaged and leak oil. 2. Check if the oil filter on the inlet side of the gear pump is blocked, which will cause difficulty in sucking oil or oil, and the phenomenon that the oil suction hose is sucked. Gear pump rotation is not correct. When the rotation of the pump is not correct, high-pressure oil will directly lead to the oil seal. As the general low-pressure skeleton oil seal can only withstand the pressure of 0.5 MPa, the oil seal will be washed out. Gear pump bearings withstand axial forces. The axial force generated is often related to the tight fit of the shaft end of the gear pump shaft and the shaft sleeve. When the plate vulcanizing machine is installed, the pump is hammered or hard-drawn through the mounting screw to subject the pump shaft to a backward axial force. When the pump shaft rotates, this backward axial force will force the pump to wear out. Because the inner surface of the gear pump is sealed by the gear end face and the end face of the sleeve, when the axial seal face wears badly, the internal axial seal of the pump will produce a certain gap, resulting in the communication of the high and low pressure oil chambers to make the oil seal flush out. . The plate vulcanizer system is overloaded, mainly due to excessive pressure or rotational speed. The poor cleanliness of the oil and the increased internal wear make the volumetric efficiency drop, and the oil leaks from the internal gap to throttle and generate heat. The outlet pipe is too thin and the oil flow rate is too high. Generally, the oil flow rate is 3 to 8 m/s.
