Blince High Pressure Oil Sealed VQ Rotary Vane Oil Pump for Excavator Hydraulic System

High performance composition vane pumps for walking machinery

Shape and introduction 

The series high pressure resistant composition vane pumps with highperformance are developed for engineering machinery application, especially for walking machinery. The main features are as follows:

1. Adopt the structure of hydraulic balanceing composition vanes, making the resistant pressure higher to maximum 21 Mpa.

2. Adopt the structure of floating side plate supporting with its function of automatic tolerance compensation, which helps to get pressure balance and high performance under high rotation speed and high pressure.

3. Adopt bimetal flexible material for side plates, which dramatically improves the engagement performance of the gears and thus makes the pumps working better and longer.

Operation parameters:

Operation and Maintenance

Hydraulic oil 

It is recomanded to adopt anti-wear hydraulic fluids with viscosity of 32cst-68cst under the temperature of 40℃, or automobile crancase oil with alphabetic marks of SC, SD,SE or SF. The recommanded viscosity under rotation speed and rated pressure should range from 13cst to 54cst with the temperature range of 49℃ to 65℃.

Cold start

In case of adopting SAE 10W type hydraulic oil with viscosity between 860cst and 54cst, the operating rotation speed and pressure shall be limited within 50% of rated rotation speed and rated pressure respectively, until the system warms up. Particular attention should be paid to make sure that the whole system including the cylinder and motor on the far away side shall be warmed up, when the pump starts up with the hydraulic oil viscosity exceeding 860cst.

High temperature operation

While working under high temperature, the viscosity shall not be less than 13cst, and the temperature shall not exceed 99℃. Otherwise, the service lifetime of pump core components and sealing parts will be reduced.
