(2) Hydraulic Test Stand
Transmission hydraulic test rig, its efficiency and speed of transmission, and better able to meet the general fuel pump various debugging requirements. Since the 1960s domestic product, is a mechanical test bed replacement products. At present, the fuel pump maintenance industry has a bigger market.

Because the product is driven hydraulic pump hydraulic motor speed to make the CV, and the machining precision hydraulic components higher, the relatively complex structure, enabling manufacturers more difficult, in the use of maintenance more difficult operation is not very convenient, big noise. Therefore, the strain in the test bed manufacturers pump oil Tsui has been basically eliminated.

(3) Slip-Test Bench
Slip-Test-bed domestic production in the late 1970s started products manufacturer in the pump Tsui and maintenance industries have larger holdings of. - Slip clutch is normally provided by the manufacturer on its own test-bed design and production, and ordinary three-phase asynchronous motor with matching, as well as some manufacturers are using direct professional motor manufacturers slip in speed motor assembly test rig.

Test-bed main characteristics of such structure is simple, easy to maintain, convenient to use, high reliability, its performance can meet Tsui pump oil production debugging and maintenance industry needs. But there are also speed control circuit performance instability, making it easy for defects such as speed control, the failures to the equipment maintenance and operation of a certain officers of the dangers of this, individual manufacturers products in the installation of the speed of the Monitor - Purchase protection, so as to effectively ensure the safety of operation of the equipment.
