Jinzhong Haopu Hydraulic Equipment Co., Ltd. was established in 2005, located at No. 3 Road, Yuci Industrial Park, Jinzhong City, Shanxi Province. The company specializes in the production of coking system hydraulic equipment, various standard and non-standard hydraulic stations, cylinders, cylinders and other woodworking presses, wooden door presses, solar presses.
The ultra-high pressure supercharger produced by the company is a reciprocating supercharger with a high-voltage output of 140MPA. It adopts a novel control principle to control the reciprocating motion. It has flexible starting and no jamming. It can replace the traditional large supercharger and ultra-high pressure pump for diamond. The press is pressurized, the volume is small, and the cost is low. The product has been put into mass production. It is divided into 60 series and 80 series single row, double row and three row forms. The double row and three row superchargers have small pressure fluctuations, which is more suitable for the production of large grain diamond.
The company has newly obtained two utility model patent certificates issued by the State Intellectual Property Office. details as follows:
Double-cylinder ultra-high pressure automatic reciprocating supercharger : a two-cylinder ultra-high pressure automatic reciprocating supercharger, comprising a two-way supercharging cylinder and a matching reversing valve, wherein the left and right piston chambers of the supercharging cylinder are respectively opened with oil ports The oil outlet of the reversing valve is connected to the oil port of the left and right piston chambers of the boosting cylinder, and the left and right piston chambers respectively open the control ports, and the two-way boosting cylinders are two, respectively, the first supercharging a cylinder and a second booster cylinder, the first booster cylinder is matched with the first reversing valve, and the second booster cylinder is matched with the second reversing valve, and the control ports of the left and right piston cavities of the first booster cylinder are respectively The two pilot ports are connected to the two pilot ports, and the control ports of the left and right piston chambers of the second booster cylinder are respectively connected with the two pilot ports of the first reversing valve. The utility model uses multi-cylinder supercharging, and the continuous control of the hydraulically controlled reversing valve between the multi-cylinders greatly enhances the stability of the supercharging, and does not require electronic control, and has wide applicability.
A hydraulically controlled reversing device and an ultrahigh pressure supercharger therefor : a hydraulically controlled reversing device, comprising a first hydraulically controlled check valve, a second hydraulically controlled check valve, a first one-way valve, a second The one-way valve, the pilot port of the liquid-controlled reversing valve is connected to the first one-way valve A port and the first hydraulic control one-way valve A port, and the hydraulic control one-way valve pilot port is connected to the second one-way valve A port and the second liquid Control the check valve A port, the pilot port of the first hydraulic control check valve is connected with the B port of the first check valve, and the pilot port of the second hydraulic control check valve is connected with the B port of the second check valve, A hydraulic control check valve and a second hydraulic control check valve are connected to the drain port of the B port. In the commutation of the utility model, the reversing one end pilot port is connected to the pressure oil in the pilot oil passage through the one-way valve, and the hydraulic control one-way valve connected at the other end pilot port is connected with the reversing end oil passage due to the pilot port thereof. The control check valve is opened, so that the other end pilot port is connected with the drain pipe to achieve the purpose of rapid pressure relief, thereby making the entire commutation process smoother.
