Weichai Power is one of the major manufacturers of high-power high-speed diesel engines in China. It mainly supplies products to domestic truck and construction machinery manufacturers. Diesel engines are mainly used for supporting end products such as heavy-duty vehicles, engineering machinery, ships, large passenger cars and generator sets. The supporting market will be expanded from single heavy-duty vehicles to construction machinery, large passenger cars, ships, generator sets and other fields.
Weichai Power recently announced its 2009 pre-additions announcement: It is expected that the company's 2009 performance will increase by a significant 50 to 100% year-on-year. The net profit attributable to shareholders of the parent company was approximately RMB 3.1 billion to RMB 3.7 billion. The performance is basically in line with expectations. The major reason for the significant increase in performance is due to the increase in sales volume and improvement in gross profit margin. In the second half of 2009, the company’s heavy truck engine sales increased significantly. It is expected that sales of Weichai power engines will be expected to reach around 320,000 units throughout the year. Fast Transmission will set a record high, exceeding 700,000 units throughout the year.
It is the company’s market diversification strategy that is compatible with the company’s active expansion of engine product coverage. The company is currently making great strides in the passenger car and marine engine market, and is progressing well. Hengtai Securities predicts that the company's sales of marine engines in 2009 will be around 4,000 units, a year-on-year increase of more than 100%. It should be noted that the ratio of passenger cars and marine engines to the total sales of the company's engines is still only about 3%, which has little impact on the company's performance.
The Plunger Pump is used in the closed circuit of hydrostatic transmission. The flow rate is proportional to the driving speed and displacement, and can be infinitely varied. Various variable control methods can be selected, such as manual, hydraulic control and electric ratio control. Multiple hydraulic control valves can be integrated to avoid overload. Different control methods can be configured according to customer needs. The degree of automation is high. Can realize remote control operation. The through shaft is designed to meet the various needs of hydraulic systems. It can replace imported Rexroth A4VG series axial piston pump.
Axial plunger variable pump with swash plate structure for closed-circuit hydrostatic transmission
Flow rate is proportional to driving speed and displacement, and can be adjusted steplessly
Swashplate swing angle increases output flow from zero to maximum
Various highly compatible control devices, providing various control and adjustment functions
Each high-pressure side is equipped with two safety valves to prevent overloading of hydrostatic transmissions (pumps and motors)
The overflow valve also has a charge valve function, and the built-in pressure cut-off valve is standard
The built-in charge pump is used as a fuel supply and control pump. The maximum charge pressure is limited by the built-in charge relief valve.
