Hydraulic pumps are capable of pushing large amounts of oil through hydraulic cylinders or hydraulic motors. In this fashion, the pump converts the mechanical energy of the drive (i.e. torque, speed) into hydrostatic energy (i.e. flow, pressure).

What is the working principle of hydraulic pump?
A hydraulic pump is a device of power that converts mechanical power into hydrostatic energy. It is used to generate flow or pressure and has enough power to overcome pressure induced by the load. Working Principle of a Hydraulic Pump: The purpose of a pump in a hydraulic system is to provide flow or pressure.

What is the function of a hydraulic pump?
A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet.

What are 3 types of hydraulic pumps?
Three different types of hydraulic pumps exist: gear pumps, piston pumps and vane pumps.

Where are hydraulic pumps used?
Hydraulic pumps are used on excavators, cranes, loaders, tractors, vacuum trucks, forestry equipment, graders, dump trucks, mining machinery, etc. Mobile applications use hydraulic pumps more prolifically than do industrial machines, because electric actuators are generally not used for mobile machinery.

What are the parts of a hydraulic pump parts?
Well, a hydraulic pump include below main components:

Valve block (Cylinder Barrel)
Valve Plate
ball guide
set plate
push rod
shoe plate
hanger (swash plate)
drive shaft
piston

Can a hydraulic pump be rebuilt?
Rebuilding of a hydraulic pump or motor can also be done with all relevant new components or parts. Therefore, just because the unit was rebuilt does not necessarily means that it is a “repaired” unit. Eventually, a rebuilt unit must go through the dynamic testing process.

How do I know if my hydraulic pump is bad?
Pump trouble is usually characterized by increased noise, increased heat, erratic operation of cylinders, difficulty or inability to develop full output, decreased speed of cylinders or hydraulic motors, or failure of the system to work at all.

Guangzhou Sonka Engineering Machinery Co., Ltd.

Location: Guangzhou, China

Business scope:excavator spare parts

Fit for machine model brand: Komatsu, Hitachi, Kobelco, Kato, Cat, Daewoo, Sumitomo, Hyundai, Volvo

Start

Sonka Company grew out of Global Engineering Machinery.

Time back in 2009, a spare parts shop named GLOBAL ENGINEERING MACHINERY established in Guangzhou City. Soon but stably, it sold its spare parts to more than 30 cities in domestic China in the same year, with the fame spreading far and wide, for the good product quality and service.

At that time the shop mainly sold mainly in seal and seal kits lines: excavator seal kits, loader seal kits, bulldozer seal kits, breaker seal kits and other construction machinery-related seals.

Growing

To meet customer’s growing needs on seal kits, in 2013, a new company named Guangzhou Huanqiu Seal Technology Co. LTD was set up to handling the seal factory. Factory manufactures all kinds of seals for construction machinery.

It then lay solid foundations for oncoming development.

HQPA stands for High Quality Product Assurance!

Expand

With rich experience and established technique, customers are satisfied with our seal kits for high quality and good performance.

And we would like to share these seal kits with the world outside China. In the year of 2014, we creates the Guangzhou Sonka Engineering Machinery Co. Ltd, a branch trading company, to deal with all the oversea business.

Prospect

In the year 2020, Sonka Company will upgrade our brand. We will set up Management Service Center in the oversea market to promote our uniform brand all over the world.
