China Surface Pumps Manufacturers

The chemical pump oil seal is a self-tightening lip seal with simple structure, small size, low cost, convenient maintenance, and low resistance torque. It can prevent the leakage of the medium and the intrusion of external dust and other harmful substances. It has a certain ability to compensate for wear, but it is not resistant to high pressure, so it is generally used on chemical pumps in low pressure occasions.

Chemical pumps rely on centrifugal principles to extract liquid materials. Chemical pumps made of special materials are suitable for pumping corrosive liquids from bottles, barrels, cylinders, pools or other containers. Due to the existence of dangers such as corrosion, volatilization, and explosion of the medium pumped by chemical pumps, the sealing performance requirements of the pump body are much higher than other types of pumps.

The oil seal of the chemical pump should be installed on the shaft with a manufacturing accuracy of h8～h9, a surface roughness of 1.6～0.8μm and a surface hardening treatment. The sealing medium should not contain solid particles and impurities, otherwise it will cause rapid wear of the oil seal and shaft and cause the seal to fail.

(3) The oil seals used on machinery should be inspected, maintained and maintained frequently when the working conditions of the oil seals are bad, the environmental temperature difference is large, the dust is too much, and the machine vibration frequently causes the mechanical force status to change constantly.

(4) If the shaft China Surface Pumps Manufacturers and bearing wear is serious; the oil seal rubber is aging or the spring fails, etc., repair and replace the corresponding parts in time.
