In the slurry pump bearing assembly, lubrication method of the bearing is roughly divided into grease lubrication and oil lubrication, and the choice of the way is related to the type, size and operating conditions of the bearing. In grease lubrication and oil lubrication, grease lubrication is the most used, about 80% of rolling bearings are using grease lubrication.
I The Characteristics of Grease Lubrication
A: The lubrication device is simple. If sealed bearings or non-sealed bearings that do not require grease are used, no additional lubrication is required (in contrast, oil lubrication systems require oil pumps, tubing, fuel tanks, etc.).
B: Grease is not easy to leak, bearing seal structure is relatively simple,
C: Easy maintenance of bearings.
D: The grease has a sealing effect to prevent external dust, moisture and other impurities from invading the bearing.
E: Easy to improve the cleanliness of the mechanical device.
II The Characteristics of Oil Lubrication
A: suitable for high-speed rotation
B: good high temperature stability, suitable for use at high temperatures.
C: can take away the internal friction heat of the bearing, good heat dissipation. When the ambient temperature of the bearing is high, oil lubrication can play a cooling role.
D: easy to remove the wear particles and dust inside the bearing.
E: can be used with gear and other bearing parts around the same lubricant, achieving common lubrication.

Company Introduction:
Shijiazhuang Hongchang Pump Co., Ltd. Was founded in 2003 and is a professional manufacturer integrating the design and manufacture of slurry pumps, dredging pumps and high chromium wear-resistant castings.
Our company is located in the Tianshan Manufacturing Base of Shijiazhuang Economic and Technological Development Zone covering an area of 4 hectares and a building area of 25, 000 square meters.
In recent years, our company has actively fulfilled its social responsibility. Continuously investing in environmental protection, reducing emissions and becoming the only casting enterprise in Shijiazhuang pump industry whose performance evaluation is Grade A.
Our company′s products are widely used in mining, electric power, coal, metallurgy, chemical, building materials and other industries, mainly exported to South Africa, Australia, the USA, Canada, Russia, Chile and other countries and regions, as Hebei Province′s key export positive list enterprises and high-tech enterprises.
Hongchang Pump Co has more than 120 employees, with models, casting, heat treatment, machining, assembly and other workshops. With an annual output of 5000 tons of high chromium alloy. We also can produce 2000 sets of pumps. Along with the whole process production capacity from models to finished products.
The casting workshop uses an advanced continuous sand mixer. Castings are made using resin sand moulding. Medium frequency electric furnaces are used in the smelting process. There are 5 (five) 3T, 1 (one) 5T and 1 (one) 10T medium frequency electric furnace, and the maximum casting weight of a single piece can reach 30T. Direct-reading spectrometer are used for pre-furnace component inspection to strictly ensure that the composition ratio of castings meets the technical requirements.
Our company has 3 resistance-type heat treatment furnaces. The temperature of the heat treatment process is strictly controlled by the computer automatically according to the set heat treatment temperature curve, avoiding the influence of manual operation. The furnaces can be used for softening, hardening, stress relief annealing and other heat treatment of castings.
Strict material ratios combined with advanced wear-resistant alloy smelting technology, casting process and heat treatment process ensure the company′s excellent casting surface, internal microstructure and reliable qualities are maintained.
Shijiazhuang Hongchang Pump Co., Ltd. Has the domestic industry advanced processing equipment and technology. The machine shop has over 40 CNC metal cutting machine tools and machining centers. The maximum rotating diameter of the vertical lathe is 6300 mm. CNC vertical lathe, boring and milling machining center and CNC wire-cutting machine tools can process parts with complex shapes with very high precision requirements.
Wear-resistant castings are machined using advanced ceramic tooling and sophisticated cutting technologies to solve the machining problem of high hardness wear-resisting materials, and greatly improves the machining efficiency of wear-resisting castings.
For impellers with hardness above 60HRC, the impeller threads are machined in the hardened state to avoid thread deformation during heat treatment.
The assembly workshop of the company is mainly engaged in the assembly of bearing assemblies and pumps. Bearing assemblies are assembled in a constant temperature controlled clean rooms, which ensures accurate and clean assembly.
The finished products warehouse undertakes the warehousing, packaging and shipping of finished products.
Quality is the foundation of our enterprise. We take great care with the development of our enterprise, with our customers as the center, and constantly improving our management and technical levels. We have won the title of "High-Tech Enterprise of Hebei Province".
