Application in hydraulic cylinder tightness

The hydraulic cylinder is an important part of the manual hydraulic forklift, and its performance determines the working performance of the forklift. The hydraulic cylinder needs to work repeatedly at high pressure to ensure that its production quality is qualified for work safety and work efficiency. The tightness test of the hydraulic cylinder is an important link in the product test. During the test, the GripSeal quick connector is needed to temporarily connect the nozzle to facilitate the test and improve the overall test efficiency.

Manual hydraulic forklift is a dual-purpose vehicle for high-lift loading, unloading and short-distance transportation. Since it does not generate sparks and electromagnetic fields, it is especially suitable for factory loading & unloading and flammable & flammable vehicles in workshops, warehouses, docks, stations, freight yards, etc., loading and unloading of explosive and fire-prohibited items. The product has the characteristics of balanced lifting, flexible rotation and convenient operation.,work safely and reliably. It is an ideal tool for reducing labor intensity, improving production efficiency, and realizing complete loading and unloading. The core component of a manual hydraulic forklift is the hydraulic cylinder.

A hydraulic cylinder is a hydraulic device that converts the hydraulic energy of linear reciprocating or oscillating motion into mechanical energy. It has a relatively simple structure and stable motion during reciprocating operation. Hydraulic cylinders are widely used in various industries such as engineering machinery, ships, machine tools, and even national defense equipment.

Hydraulic cylinders are used in high-torque fields, engineering machinery, and vehicles. Based on the direction of oil intake, the blades drive the rotor to reciprocate. When one oil port takes in pressure oil and the other oil port returns oil, the blades swing in one direction under pressure and drive the shaft to deflect at a certain angle. When the oil inlet and outlet ports are swapped, the motor reverses.

hydraulic cylinders ensure no oil leakage is by having good sealing performance and the ability to withstand high pressure inside the cylinder. The components of hydraulic cylinders require high precision during welding and machining, and various types of sealing rings are used as well.

The hydraulic cylinder allows oil leak within a controllable range. The piston rod is in a state of dry friction during reciprocating motion, which will increase the abrasion of the parts and reduce the service life. Therefore, a certain amount of oil leak is allowed for lubrication and friction reduction, but we require no oil leak when the piston rod is in a static state.

Product performance test: We do oil test and ensure excellent sealing performance before we send out the goods. Test condition: Apply oil under a positive pressure of 28Mpa and detect oil leak of the product. Common threads M14, M16, M20, M22, M27, 1/4G, and 3/8G are equipped with female thread and male thread. The test medium is hydraulic oil. Manual operation.

GripSeal quick connector G80/G85 series provide user-friendly expericence for customers during the whole test. The main advantanges are as below:

• 1. High-temperature resistance
• 2. Liquid medium
• 3. Excellent sealing performance (Many products has sink hole. We use customized double-sided sealing ring for excellent sealing performance).
• 4. Safe and reliable
• 5. High-efficient and cost-effective (We can test as much as 3000pcs products for the client per day, which greatly improving customer’s working efficiency and reducing production cost).
